Some small business owners overlook Roth IRAs because they assume their income is too high for them to qualify to make Roth contributions. Others may think their current tax rate is higher than it will be in retirement, making current tax deductions more valuable than future tax-free distributions. However, if you don’t at least consider contributing to a Roth IRA, you may be missing a potentially valuable tax-saving opportunity.

Rules and restrictions

Roth IRA contributions aren’t deductible, but they’re beneficial because you reap tax savings on the back end. (More on that later.) For 2026, the annual contribution limit is $7,500 (up from $7,000 for 2025). If you’ll be 50 or older by the end of the tax year, you can make an additional $1,100 catch-up contribution. The same limits apply to traditional IRAs, and your Roth IRA limit is reduced by any traditional IRA contributions you make for the year.

But your ability to make Roth IRA contributions is phased out if your modified adjusted gross income (MAGI) exceeds certain levels. For 2026, the phaseout ranges are:

$153,000 to $168,000 for single individuals and heads of households, and
$242,000 to $252,000 for married couples filing jointly.

If your MAGI falls within the range, your contribution limit is reduced. If it equals or exceeds the top of the range, your ability to contribute is eliminated.

Married individuals who file separately and live apart for the full year are treated as single individuals for the income limitations. However, separate filers who live together at any time during the year are subject to a phaseout range of $0 to $10,000.

Is your income too high to qualify?

At first glance, these figures may cause you to assume you’re ineligible for Roth contributions. But take another look.

When calculating MAGI for Roth IRA eligibility purposes, self-employed individuals may be able to significantly reduce their taxable income through deductions for:

Certain business expenses, such as rent, home office expenses and computer costs,
Contributions to a tax-deferred retirement plan, such as a solo 401(k), SEP IRA or SIMPLE,
Health insurance premiums, and
Self-employment tax.

These deductions, along with others, are subtracted when calculating MAGI. Therefore, a self-employed person can have relatively high gross income from his or her business while having a much lower MAGI.

The choice between contributing to a Roth IRA or a tax-deferred account isn’t an all-or-nothing proposition. Depending on your situation, you may decide to contribute to both types of accounts, subject to applicable limits. Contributing to a tax-deferred retirement plan provides immediate tax savings. And, because these contributions lower your MAGI, they may put your taxable income below the phaseout limits for Roth IRA contributions.

Additional benefits

The main upside of contributing to a Roth IRA is that qualified withdrawals won’t be taxed. This can be advantageous if you expect to be in a higher tax bracket in retirement or if tax rates increase. Moreover, withdrawals from Roth accounts aren’t counted when calculating the taxable portion of your Social Security benefits.

Another Roth IRA advantage is that you don’t have to take withdrawals at any age, meaning the account can continue to grow tax-free. With a traditional IRA (and other tax-deferred retirement accounts), at age 73, you generally must begin to take required minimum distributions or face a penalty equal to 25% of the amount you should have withdrawn but didn’t. In addition, if your Roth IRA is passed on to your heirs, it can continue to grow tax-free, and their withdrawals generally will be tax-free. However, most nonspouse beneficiaries will be required to deplete the account within 10 years of inheriting it.

Bottom line

A Roth IRA offers many potential benefits, and self-employed individuals may be more likely to qualify to make Roth IRA contributions than other taxpayers with similar gross incomes. But they aren’t right for every situation. We can help evaluate your eligibility and develop a long-term retirement strategy that aligns with your personal and financial goals.

If you run your business as a C corporation, you may be eligible for a potentially significant tax break for qualified small business (QSB) stock. This opportunity has existed for years, but recent tax law changes have enhanced it.

What’s a QSB corporation?

QSB corporations are a special type of C corporation. At the entity level, QSB corporations are generally treated as regular C corporations for legal and federal income tax purposes. So, most of the standard advantages and disadvantages of C corporation status apply equally to QSB corporations, including the 21% flat federal income tax rate on corporate income. However, QSB shareholders can potentially enjoy a significant tax advantage: A special gain exclusion rule can allow them to avoid the federal income tax hit on up to 100% of the gain from selling QSB stock.

C corporations that own QSB stock aren’t eligible for the gain exclusion. But sales of QSB stock held by pass-through business entities — such as S corporations, partnerships and, typically, limited liability companies — may be eligible. The break is effectively passed through to individual pass-through entity owners.

Which shares qualify as QSB stock?

To be eligible for the QSB stock gain exclusion, several requirements must be met, including the following:

You must acquire the shares upon original issuance by the corporation or by gift or inheritance.
The corporation must be a QSB corporation on the date the stock is issued and for substantially all the time you own the shares. Among other things, this means it must not have assets that exceed $75 million ($50 million if the stock was issued on or before July 4, 2025). The $75 million limit will be indexed for inflation after 2026.
The corporation must actively conduct a qualified business. Service businesses and certain other businesses don’t qualify. (Contact us for a complete list of nonqualified businesses.)

Timing is also critical. To take advantage of the 100% gain exclusion for sales of QSB stock, you must have acquired the shares after September 27, 2010, and held them for at least five years.

How did the OBBBA expand the exclusion?

In addition to raising the QSB asset ceiling, the One Big Beautiful Bill Act (OBBBA) enhanced the gain exclusion rules for QSB shares acquired after July 4, 2025. It allows a 50% gain exclusion for QSB stock held for at least three years and a 75% gain exclusion for QSB stock held for at least four years. The 100% gain exclusion still applies to QSB stock held for at least five years.

For QSB shares acquired after July 4, 2025, your excludable gain for any year is limited to the greater of:

10 times your aggregate tax basis in the QSB stock that was sold, or
$15 million ($7.5 million if you were married but filed separately), reduced by the amount of gain you excluded in prior tax years from sales of QSB stock issued by the same corporation.

When the $15 million (or $7.5 million) restriction applies, it’s effectively a lifetime limitation.

Next steps

The gain exclusion for QSB stock and the flat 21% corporate federal income tax rate are two powerful incentives to operate a business as a QSB corporation. You can potentially convert an existing unincorporated business into a QSB corporation by incorporating it. Contact us to learn more about this tax-saving strategy. We can help you navigate the complex rules and requirements.

If you used one or more vehicles in your business during 2025, you may be eligible for valuable tax deductions on your 2025 income tax return. Businesses can generally deduct expenses attributable to business use of a vehicle plus depreciation. However, the rules are complicated, and your deduction may be affected by factors such as the vehicle’s weight, business vs. personal use, and whether you use the actual expense method or the cents-per-mile rate.

Actual expenses plus depreciation

The year you place a vehicle in service, you can choose to deduct the actual expenses attributable to your business vehicle use or, if the vehicle is a car, SUV, van, pickup or panel truck, claim the cents-per-mile deduction (discussed later). Deductible expenses include gas, oil, tires, insurance, repairs, licenses and vehicle registration fees. You’ll need to track and substantiate these expenses.

If you use the actual expense method, you also can claim a depreciation deduction for the vehicle by making a separate depreciation calculation for each year until the vehicle is fully depreciated. According to the general rule, you calculate depreciation over a six-year span for a percentage of the purchase cost as follows:

Year 1 — 20%
Year 2 — 32%
Year 3 — 19.2%
Year 4 — 11.52%
Year 5 — 11.52%
Year 6 — 5.76%

If a vehicle is used 50% or less for business purposes, you must use the straight-line method (10% in Years 1 and 6 and 20% in Years 2 through 5) to calculate depreciation deductions instead of the percentages listed above.

Depending on the cost of a passenger auto, your deduction may be less than the percentage of cost above because “luxury auto” annual depreciation ceilings apply. These are indexed for inflation and may change annually. For a passenger auto placed in service in 2025, generally the ceilings are as follows:

Year 1 — $20,200 ($12,200 if you don’t claim first-year bonus depreciation)
Year 2 — $19,600
Year 3 — $11,800
Each remaining year until the vehicle is fully depreciated — $7,060

These ceilings are proportionately reduced for any nonbusiness use.

More favorable depreciation rules apply to heavier SUVs, pickups and vans. For example, 100% bonus depreciation or the normal Section 179 expensing limit ($2.5 million for 2025) generally is available for vehicles with a gross vehicle weight rating (GVWR) of more than 14,000 pounds. A reduced Sec. 179 limit of $31,300 applies to vehicles (typically SUVs) rated at more than 6,000 pounds but no more than 14,000 pounds. Again, this favorable tax treatment is available only if the vehicle is used more than 50% for business.

The cents-per-mile method

The 2025 cents-per-mile rate for the business use of a car, SUV, van, pickup or panel truck is 70 cents (increasing to 72.5 cents for 2026). This rate applies to gasoline- and diesel-powered vehicles as well as electric and hybrid-electric vehicles. A depreciation allowance is built into the rate, so you can’t claim both the depreciation deductions discussed earlier and the cents-per-mile rate for the same vehicle.

The rate is adjusted annually. It’s based on an annual study commissioned by the IRS about the fixed and variable costs of operating a vehicle, including gas, maintenance, repairs and depreciation. Occasionally, if there’s a substantial change in average gas prices, the IRS will change the cents-per-mile rate midyear.

The cents-per-mile rate is beneficial if you don’t want to keep track of actual vehicle-related expenses or worry about depreciation calculations. Although you don’t have to account for all your actual expenses, you still must record certain information, such as the mileage for each business trip, the date and the destination.

Choosing or changing your method

There’s much to consider before deciding whether to use the actual expense method or cents-per-mile method to deduct expenses for a vehicle your business placed in service in 2025. For a vehicle placed in service earlier, if you previously deducted actual expenses for the vehicle, you can’t use the cents-per-mile rate for 2025 (or any other future year). However, if you previously used the cents-per-mile rate, you can switch to the actual expense method in a later year — but you can claim only straight-line depreciation.

If you lease a business vehicle, there also are deduction opportunities but the rules are different. Contact us if you’d like more information. We can also answer questions about claiming 2025 business vehicle expenses on your 2025 return or planning for and tracking 2026 expenses.

Interest paid or accrued by a business is generally deductible for federal tax purposes. But limitations apply. Now some changes under the One Big Beautiful Bill Act (OBBBA) will result in larger deductions for affected taxpayers.

Limitation basics

The deduction for business interest expense for a particular tax year is generally limited to 30% of the taxpayer’s adjusted taxable income (ATI). That taxpayer could be you or your business entity, such as a partnership, limited liability company (LLC), or C or S corporation. Any business interest expense that’s disallowed by this limitation is carried forward to future tax years.

Business interest expense means interest on debt that’s allocable to a business. For partnerships, LLCs that are treated as partnerships for tax purposes, and S corporations, the limitation on the business interest expense deduction is applied first at the entity level and then at the owner level under complex rules.

The limitation on the business interest expense deduction is applied before applying the passive activity loss (PAL) limitation rules, the at-risk limitation rules and the excess business loss disallowance rules. For pass-through entities, those rules are applied at the owner level. But the limitation on the business interest expense deduction is generally applied after other federal income tax provisions that disallow, defer or capitalize interest expense.

The changes

The OBBBA liberalizes the definition of ATI and expands what constitutes floor plan financing. For taxable years beginning in 2025 and beyond, the OBBBA calls for ATI to be computed before any deductions for depreciation, amortization or depletion. This change more closely aligns the definition of ATI to the financial accounting concept of earnings before interest, taxes, depreciation and amortization (EBITDA) and increases ATI, thus increasing allowable deductions for business interest expense.

For taxable years beginning in 2025 and beyond, the OBBBA also expands the definition of floor plan financing to cover financing for trailers and campers that are designed to provide temporary living quarters for recreational, camping or seasonal use and that are designed to be towed by or affixed to a motor vehicle. For affected businesses, this change also increases allowable deductions for business interest expense.

Exceptions to the rules

There are several exceptions to the rules limiting the business interest expense deduction. First, there’s an exemption for businesses with average annual gross receipts for the three-tax-year period ending with the prior tax year that don’t exceed the inflation-adjusted threshold. For tax years beginning in 2025, the threshold is $31 million. For tax years beginning in 2026, the threshold is $32 million.

The following businesses are also exempt:

An electing real property business that agrees to depreciate certain real property assets over longer periods.
An electing farming business that agrees to depreciate certain farming property assets over longer periods.
Any business that furnishes the sale of electrical energy, water, sewage disposal services, gas or steam through a local distribution system, or transportation of gas or steam by pipeline, if the rates are established by a specified governing body.

If you operate a real property or farming business and are considering electing out of the business interest expense deduction limitation, you must evaluate the trade-off between currently deducting more business interest expense and slower depreciation deductions.

It’s complicated

The rules limiting the business interest expense deduction are complicated. If your business may be affected, contact us. We can help assess the impact.

If you’re considering guaranteeing, or are asked to guarantee, a loan to your closely held corporation, it’s important to understand the potential tax consequences. Acting as a guarantor, endorser or indemnitor means that if the corporation defaults, you could be responsible for repaying the loan. Without planning ahead, you may face unexpected tax implications.

A business bad debt

If you’re compelled to make good on the obligation, the payment of principal or interest in discharge of the obligation generally results in a bad debt deduction. This may be either a business or a nonbusiness bad debt deduction. If it’s a business bad debt, it’s deductible against ordinary income. A business bad debt can be either totally or partly worthless. If it’s a nonbusiness bad debt, it’s deductible as a short-term capital loss, which is subject to certain limitations. A nonbusiness bad debt is deductible only if it’s totally worthless.

To be treated as a business bad debt, the guarantee must be closely related to your trade or business. If the reason for guaranteeing the corporation loan is to protect your job, the guarantee is considered closely related to your trade or business as an employee. But employment must be the dominant motive. If your annual salary exceeds your investment in the corporation, this generally shows that the dominant motive for the guarantee is to protect your job. On the other hand, if your investment in the corporation substantially exceeds your annual salary, that’s evidence that the guarantee is primarily to protect your investment rather than your job.

Proving the relationship

Except in the case of job guarantees, it may be difficult to show the guarantee is closely related to your trade or business. You have to show that the guarantee is related to your business as a promoter, or that the guarantee is related to some other trade or business separately carried on by you.

If the reason for guaranteeing your corporation’s loan isn’t closely related to your trade or business and you’re required to pay off the loan, you can take a nonbusiness bad debt deduction if you show that your reason for the guarantee was to protect your investment, or you entered the guarantee transaction with a profit motive.

Note: The IRS and courts will scrutinize the dominant motive carefully. Reasonable compensation doesn’t always mean money. It can include protecting employment or business interests.

Additional requirements

In addition to satisfying the above requirements, a business or nonbusiness bad debt is deductible only if you meet these three conditions:

You have a legal duty to make the guaranty payment (although there’s no requirement that a legal action be brought against you).
The guaranty agreement is entered into before the debt becomes worthless.
You receive reasonable consideration (not necessarily cash or property) for entering into the guaranty agreement.

Any payment you make on a loan you guaranteed is deductible as a bad debt in the year you make it, unless the agreement (or local law) provides for a right of subrogation against the corporation. If you have this right, or some other right to demand payment from the corporation, you can’t take a bad debt deduction until the rights become partly or totally worthless.

These are only some of the possible tax consequences of guaranteeing a loan to your closely held corporation. Consult with us to learn all the implications and to help ensure the best tax results.

Do you and your spouse together operate a profitable unincorporated small business? If so, you face some challenging tax issues.

The partnership issue

An unincorporated business with your spouse is classified as a partnership for federal income tax purposes, unless you can avoid that treatment. Otherwise, you must file an annual partnership return using Form 1065. In addition, you and your spouse must be issued separate Schedules K-1, which allocate the partnership’s taxable income, deductions and credits between the two of you. This is only the beginning of the unwelcome tax compliance tasks.

The self-employment tax issue

Self-employment (SE) tax is how the government collects Social Security and Medicare taxes from self-employed individuals. For 2025, the SE tax consists of 12.4% Social Security tax on the first $176,100 of net SE income plus 2.9% Medicare tax. Once your 2025 net SE income surpasses the $176,100 ceiling, the Social Security tax component of the SE tax ends. But the 2.9% Medicare tax component continues before increasing to 3.8% — because of the 0.9% additional Medicare tax — if the combined net SE income of a married joint-filing couple exceeds $250,000. (This doesn’t include investment income.)

With your joint Form 1040, you must include a Schedule SE to calculate SE tax on your share of the net SE income passed through to you by your spousal partnership. The return must also include a Schedule SE for your spouse to calculate the tax on your spouse’s share of net SE income passed through to him or her. This can significantly increase your SE tax liability.

For example, let’s say you and your spouse each have net 2025 SE income of $150,000 ($300,000 total) from your profitable 50/50 partnership business. The SE tax on your joint tax return is a whopping $45,900 ($150,000 × 15.3% × 2). That’s on top of regular federal income tax. (However, you do get an income deduction for half of the SE tax.)

Here are three possible tax-saving solutions.

1. Use an IRS-approved method to minimize SE tax in a community property state

Under IRS guidance (Revenue Procedure 2002-69), there’s an exception to the general rule that spouse-run businesses are treated as partnerships. For federal tax purposes, you can treat an unincorporated spousal business in a community property state as a sole proprietorship operated by one of the spouses. By effectively allocating all the net SE income to the proprietor spouse, only the first $176,100 of net SE income is hit with the 12.4% Social Security tax. That can cut your SE tax bill.

2. Convert a spousal partnership into an S corporation and pay modest salaries

If you and your unincorporated spousal business aren’t in a community property state, consider converting the business to S corp status to reduce Social Security and Medicare taxes. That way, only the salaries paid to you and your spouse get hit with the Social Security and Medicare tax, collectively called FICA tax. You can then pay reasonable, but not excessive, salaries to you and your spouse as shareholder-employees while paying out most or all remaining corporate cash flow to yourselves as FICA-tax-free cash distributions. Keep in mind that S corps come with their own compliance obligations.

3. Disband your partnership and hire your spouse as an employee

You can disband the existing spousal partnership and start running the operation as a sole proprietorship operated by one spouse. Then hire the other spouse as an employee of the proprietorship. Pay that spouse a modest cash salary. You must withhold 7.65% from the salary to cover the employee-spouse’s share of the Social Security and Medicare taxes. The proprietorship must also pay 7.65% as the employer’s half of the taxes. However, because the employee-spouse’s salary is modest, the FICA tax will also be modest.

With this strategy, you file only one Schedule SE — for the spouse treated as the proprietor — with your joint tax return. That minimizes the SE tax because no more than $176,100 (for 2025) is exposed to the 12.4% Social Security portion of the SE tax.

Additional bonus: You may be able to provide certain employee benefits to your spouse, such as retirement contributions, which may provide more tax savings.

We can help

Having a profitable unincorporated business with your spouse that’s classified as a partnership for federal income tax purposes can lead to compliance headaches and high SE tax bills. Work with us to identify appropriate tax-saving strategies.

If you own an unincorporated small business, you may be frustrated with high self-employment (SE) tax bills. One way to lower your SE tax liability is to convert your business to an S corporation.

SE tax basics

Sole proprietorship income, as well as partnership income that flows through to partners (except certain limited partners), is subject to SE tax. These rules also apply to single-member LLCs that are treated as sole proprietorships for federal tax purposes and multi-member LLCs that are treated as partnerships for federal tax purposes.

In 2025, the maximum federal SE tax rate of 15.3% hits the first $176,100 of net SE income. That includes 12.4% for the Social Security tax and 2.9% for the Medicare tax. Together, we’ll refer to them as federal employment taxes.

The rate drops after SE income hits $176,100 because the Social Security component goes away above the Social Security tax ceiling of $176,100 for 2025. But the Medicare tax continues to accrue at a 2.9% rate, and then increases to 3.8% at higher income levels because of the 0.9% additional Medicare tax. This 0.9% tax applies when wages and SE income exceed $200,000 for singles and heads of households, $250,000 for married couples filing jointly and $125,000 for married couples filing separately.

Tax reduction strategy

To lower your SE tax bill, consider converting your unincorporated small business into an S corp and then paying yourself (and any other shareholder-employees) a modest salary. Distribute most (or all) of the remaining corporate cash flow to the shareholder-employee(s) as federal-employment-tax-free distributions.

S corp taxable income passed through to a shareholder-employee and S corp cash distributions paid to a shareholder-employee aren’t subject to federal employment taxes. Only wages paid to shareholder-employees are subject to them. This favorable tax treatment places S corps in a potentially more favorable position than businesses conducted as sole proprietorships, partnerships or LLCs.

The caveats

However, this strategy isn’t right for every business. Here are some considerations:

1. Operating as an S corp and paying yourself a modest salary saves SE tax, but the salary must be reasonable. Otherwise, you run the risk of the IRS auditing your business and imposing back employment taxes, interest and penalties.

You can minimize that risk if you gather objective market evidence to demonstrate that outsiders could be hired to perform the same work for salaries equal to what you’re paying.

2. A potentially unfavorable side effect of paying modest salaries to an S corp shareholder-employee is that it can reduce your ability to make deductible contributions to tax-favored retirement accounts. If the S corp maintains a SEP or traditional profit-sharing plan, the maximum annual deductible contribution for each shareholder-employee is limited to 25% of his or her salary.

So, the lower the salary, the lower the maximum contribution. However, if the S corp sets up a 401(k) plan, paying modest salaries won’t preclude generous contributions.

3. Operating as an S corp requires extra administrative hassle. For example, you must file a separate federal return (and possibly a state return).

In addition, you must scrutinize transactions between S corps and shareholders for potential tax consequences, including any transfers of assets from an existing sole proprietorship or partnership to the new S corp. State-law corporation requirements, such as conducting board meetings and keeping minutes, must be respected.

Mechanics of converting

To convert an existing sole proprietorship or partnership to an S corp, a corporation must be formed under applicable state law, and business assets must be contributed to the new corporation. Then, an S election must be made for the new corporation by a separate form with the IRS by no later than March 15 of the calendar year, if you want the business to be treated as an S corp for that year.

Suppose you currently operate your business as a domestic LLC. In that case, it generally isn’t necessary to go through the legal step of incorporation to convert the LLC into an entity that will be treated as an S corp for federal tax purposes. The reason is because the IRS allows a single-member LLC or multi-member LLC that otherwise meets the S corp qualification rules to simply elect S corporation status by filing a form with the IRS. However, if you want your LLC to be treated as an S corp for the calendar year, you also must complete this paperwork by no later than March 15 of the year.

Weighing the upsides and downsides

Converting an existing unincorporated business into an S corp to reduce federal employment taxes can be a wise tax move under the right circumstances. That said, consult with us so we can examine all implications before making the switch.

Are you starting a business with partners and deciding on the right entity? An S corporation might be the best choice for your new venture.

One benefit of an S corporation

One major advantage of an S corporation over a partnership is that shareholders aren’t personally liable for corporate debts. To ensure this protection, it’s crucial to:

Adequately finance the corporation,
Maintain the corporation as a separate entity, and
Follow state-required formalities (for example, by filing articles of incorporation, adopting bylaws, electing a board of directors and holding organizational meetings).

Handling losses

If you anticipate early losses, an S corporation is more favorable than a C corporation from a tax perspective. Shareholders in a C corporation generally don’t benefit from such losses. However, as an S corporation shareholder, you can deduct your share of losses on your personal tax return, up to your basis in the stock and any loans you made to the entity. Losses exceeding your basis can be carried forward and deducted in the future when there’s sufficient basis.

Profits and taxes

Once the S corporation starts earning profits, the income is taxed directly to you, whether or not it’s distributed. It will be reported on your individual tax return and combined with income from other sources. Your share of the S corporation’s income isn’t subject to self-employment tax, but your wages will be subject to Social Security taxes. If the income qualifies as qualified business income (QBI), you can take the 20% pass-through deduction, subject to various limitations.

Note: The QBI deduction is set to expire after 2025 unless extended by Congress. However, the deduction will likely be extended and maybe even made permanent under the Tax Cuts and Jobs Act extension being negotiated in Congress.

Fringe benefits

If you plan to offer fringe benefits like health and life insurance, be aware that the costs for a more than 2% shareholder are deductible by the entity but taxable to the recipient.

Protecting S status

Be cautious about transferring stock to ineligible shareholders (for example, another corporation, a partnership or a nonresident alien), as this could terminate the S election, making the corporation a taxable entity. To avoid this risk, have each shareholder sign an agreement not to make transfers that would jeopardize the S election. Also, be aware that an S corporation can’t have more than 100 shareholders.

Final steps

Before making your final decision on the entity type, consult with us. We can answer your questions and help you launch your new venture successfully.

Potential upcoming tax changes

These are only some of the tax limits and deductions that may affect your business, and additional rules may apply. But there’s more to keep in mind. With President Trump back in the White House and the Republicans controlling Congress, several tax policy changes have been proposed and could potentially be enacted in 2025. For example, Trump has proposed lowering the corporate tax rate (currently 21%) and eliminating taxes on overtime pay, tips, and Social Security benefits.

The nationwide price of gas is slightly higher than it was a year ago and the 2025 optional standard mileage rate used to calculate the deductible cost of operating an automobile for business has also gone up. The IRS recently announced that the 2025 cents-per-mile rate for the business use of a car, van, pickup or panel truck is 70 cents. In 2024, the business cents-per-mile rate was 67 cents per mile. This rate applies to gasoline and diesel-powered vehicles as well as electric and hybrid-electric vehicles.

The process of calculating rates

The 3-cent increase from the 2024 rate goes along with the recent price of gas. On January 17, 2025, the national average price of a gallon of regular gas was $3.11, compared with $3.08 a year earlier, according to AAA Fuel Prices. However, the standard mileage rate is calculated based on all the costs involved in driving a vehicle — not just the price of gas.

The business cents-per-mile rate is adjusted annually. It’s based on an annual study commissioned by the IRS about the fixed and variable costs of operating a vehicle, including gas, maintenance, repairs and depreciation. Occasionally, if there’s a substantial change in average gas prices, the IRS will change the cents-per-mile rate midyear.

Standard rate or real expenses

Businesses can generally deduct the actual expenses attributable to business use of a vehicle. These include gas, oil, tires, insurance, repairs, licenses and vehicle registration fees. In addition, you can claim a depreciation allowance for the vehicle. However, in many cases, certain limits apply to depreciation write-offs on vehicles that don’t apply to other types of business assets.

The cents-per-mile rate is beneficial if you don’t want to keep track of actual vehicle-related expenses. With this method, you don’t have to account for all your actual expenses. However, you still must record certain information, such as the mileage for each business trip, the date and the destination.

Using the cents-per-mile rate is also popular with businesses that reimburse employees for business use of their personal vehicles. These reimbursements can help attract and retain employees who drive their personal vehicles a great deal for business purposes. Why? Under current law, employees can’t deduct unreimbursed employee business expenses, such as business mileage, on their own income tax returns.

If you do use the cents-per-mile rate, keep in mind that you must comply with various rules. If you don’t comply, the reimbursements could be considered taxable wages to the employees.

When you can’t use the standard rate

There are some cases when you can’t use the cents-per-mile rate. It partly depends on how you’ve claimed deductions for the same vehicle in the past. In other situations, it depends on if the vehicle is new to your business this year or whether you want to take advantage of certain first-year depreciation tax breaks on it.

As you can see, there are many factors to consider in deciding whether to use the standard mileage rate to deduct vehicle expenses. We can help if you have questions about tracking and claiming such expenses in 2025 — or claiming 2024 expenses on your 2024 income tax return.
