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. These and other potential changes could have wide-ranging impacts on businesses and individuals. It’s important to stay informed. Consult with us if you have questions about your situation.

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.

New and used “heavy” SUVs, pickups and vans placed in service in 2025 are potentially eligible for big first-year depreciation write-offs. One requirement is you must use the vehicle more than 50% for business. If your business usage is between 51% and 99%, you may be able to deduct that percentage of the cost in the first year. The write-off will reduce your federal income tax bill and your self-employment tax bill, if applicable. You might get a state tax income deduction too.

Setting up a business office in your home for this year can also help you collect tax savings. Here’s what you need to know about the benefits of combining these two tax breaks.

First, buy a suitably heavy vehicle

The generous first-year depreciation deal is only available for an SUV, pickup, or van with a manufacturer’s gross vehicle weight rating (GVWR) above 6,000 pounds that’s purchased (not leased). First-year depreciation deductions for lighter vehicles are subject to smaller depreciation limits of up to $20,400 in 2024. (The 2025 amount hasn’t come out yet.)

It’s not hard to find attractive vehicles with GVWRs above the 6,000-pound threshold. Examples include the Cadillac Escalade, Jeep Grand Cherokee, Chevy Tahoe, Ford Explorer, Lincoln Navigator, and many full-size pickups. You can usually find the GVWR on a label on the inside edge of the driver’s side door.

Take advantage of generous depreciation deductions

Favorable depreciation rules apply to heavy SUVs, pickups and vans that are used over 50% for business because they’re classified as transportation equipment for federal income tax purposes. Three factors to keep in mind:

First-year Section 179 deductions. Many businesses can write off most or all of the business-use portion of a heavy vehicle’s cost in year 1 under the Section 179 deduction privilege. The maximum Sec. 179 deduction for tax years beginning in 2024 is $1.25 million.
Limited Sec. 179 deductions for heavy SUVs. There’s a limit on Sec. 179 deductions for heavy SUVs with GVWRs between 6,001 and 14,000 pounds. For tax years beginning in 2025, the limit is $31,300.
First-year bonus depreciation. For heavy vehicles placed in service in 2025, the first-year bonus depreciation percentage is currently 40%, but future legislation may allow a bigger write-off. There are several limitations on Sec. 179 deductions but no limits on 40% bonus depreciation. So, bonus depreciation can help offset the impact of Sec. 179 limitations, if applicable.

Then, qualify for home office deductions

Again, the favorable first-year depreciation rules are only allowed if you use your heavy SUV, pickup, or van over 50% for business.

You’re much more likely to pass the over-50% test if you have an office in your home that qualifies as your principal place of business. Then, all the commuting mileage from your home office to temporary work locations, such as client sites, is considered business mileage. The same is true for mileage between your home office and any other regular place of business, such as another office you keep. This is also the case for mileage between your other regular place of business and temporary work locations.

Bottom line: When your home office qualifies as a principal place of business, you can easily rack up plenty of business miles. That makes passing the over-50%-business-use test for your heavy vehicle much easier.

How do you make your home office your principal place of business? The first way is to conduct most of your income-earning activities there. The second way is to conduct administrative and management chores there. But don’t make substantial use of any other fixed location (like another office) for these chores.

Key points: You must use the home office space regularly and exclusively for business throughout the year. Also, if you’re employed by your own corporation (as opposed to being self-employed), you can’t deduct home office expenses under the current federal income tax rules.

Double tax break

You can potentially claim generous first-year depreciation deductions for heavy business vehicles and also claim home office deductions. The combination can result in major tax savings. Contact us if you have questions or want more information about this strategy.

According to the U.S. Bureau of Labor Statistics, the unemployment rate continues to be historically low, ranging from 4.0% to 4.3% from May to November of 2024. With today’s hiring challenges, business owners should be aware that the Work Opportunity Tax Credit (WOTC) is available to employers that hire workers from targeted groups who face significant barriers to employment. The tax credit is generally worth as much as $2,400 for each eligible employee (higher for certain veterans and “long-term family assistance recipients”). It’s generally limited to eligible employees who begin working for the employer before January 1, 2026.

To satisfy a requirement of the WOTC, a pre-screening notice must be completed by the job applicant and the employer on or before the day a job offer is made. This is done by filing Form 8850, Pre-Screening Notice and Certification Request for the Work Opportunity Credit.

The targeted groups

An employer is eligible for the credit only for qualified wages paid to a member of a targeted group. These groups are:

Qualified IV-A recipients who are members of families receiving assistance under the Temporary Assistance for Needy Families (TANF) program,
Qualified veterans,
Qualified ex-felons,
Designated community residents,
Vocational rehabilitation referrals,
Qualified summer youth employees,
Qualified members of families in the Supplemental Nutritional Assistance Program (SNAP),
Qualified Supplemental Security Income recipients,
Long-term family assistance recipients, and
Qualified long-term unemployed individuals.

Details to qualify

To qualify for the credit, there are a number of requirements. For example, each employee must have completed at least 120 hours of service in their first year of service for the employer. Also, the credit isn’t available for certain employees who are related to or who previously worked for the employer.

There are different rules and credit amounts for certain employees. The maximum credit available for first-year wages is generally $2,400 for each employee, $4,000 for long-term family assistance recipients, and $4,800, $5,600 or $9,600 for certain veterans. Additionally, for long-term family assistance recipients, there’s a 50% credit for up to $10,000 of second-year wages, resulting in a total maximum credit over two years of $9,000.

For summer youth employees, the wages must be paid for services performed during any 90-day period between May 1 and September 15. The maximum credit available for summer youth employees is $1,200 per employee.

A win for you and your employees

In some cases, employers may elect not to claim the WOTC. In limited circumstances, the rules may prohibit the credit or require allocating it. However, the credit can be advantageous for most employers hiring from targeted groups — and it can result in jobs for those who need them. Contact us with questions or for more information about your situation.

Understanding how to deduct transportation costs could significantly reduce the tax burden on your small business. You and your employees likely incur various local transportation expenses each year, and they have tax implications.

Let’s start by defining “local transportation.” It refers to travel when you aren’t away from your tax home long enough to require sleep or rest. Your tax home is the city or general area in which your main place of business is located. Different rules apply if you’re away from your tax home for significantly more than an ordinary workday and you need sleep or rest to do your work.

Your work location

The most important feature of the local transportation rules is that your commuting costs aren’t deductible. In other words, the fare you pay or the miles you drive to get to work and home again are personal and not for business purposes. Therefore, no deduction is available. This is the case even if you work during the commute (for example, via a cell phone or laptop, performing business-related tasks on the subway).

An exception applies for commuting to a temporary work location outside of the metropolitan area where you live and normally work. “Temporary,” for this purpose, means a location where your work is realistically expected to last (and does, in fact, last) for no more than a year.

Work location to other sites

On the other hand, once you get to your work location, the cost of any local trips you take for business purposes is a deductible business expense. So, for example, the cost of travel from your office to visit a customer or pick up supplies is deductible. Similarly, if you have two business locations, the cost of traveling between them is deductible.

Recordkeeping

If your deductible trip is by taxi or public transportation, save a receipt or note the expense in a logbook. Record the date, amount spent, destination and business purpose. If you use your own car, note the miles driven instead of the amount spent. Also, note any tolls paid or parking fees, and keep receipts.

You must allocate your automobile expenses between business and personal use based on miles driven during the year. Proper recordkeeping is crucial in the event the IRS challenges you.

Your deduction can be computed using:

The standard mileage rate (for 2024, 67 cents per business mile) plus tolls and parking, or
Actual expenses (including depreciation, subject to limitations) for the portion of car use allocable to the business. For this method, you’ll need to keep track of all costs for gas, repairs and maintenance, insurance, interest on a car loan, and any other car-related costs.

Employees vs. self-employed

From 2018–2025, under the Tax Cuts and Jobs Act, employees can’t deduct unreimbursed local transportation costs. That’s because “miscellaneous itemized deductions” — including employee business expenses — are suspended (not allowed) for these years. (Self-employed taxpayers can deduct the expenses discussed in this article.) But beginning in 2026, business expenses (including unreimbursed employee auto expenses) of employees are scheduled to be deductible again, as long as the employee’s total miscellaneous itemized deductions exceed 2% of adjusted gross income. However, with Republican control in Washington, this unfavorable provision may be extended by Congress, and miscellaneous itemized deductions won’t be allowed.

As we approach 2025, changes are coming to the Social Security wage base. The Social Security Administration recently announced that the wage base for computing Social Security tax will increase to $176,100 for 2025 (up from $168,600 for 2024). Wages and self-employment income above this amount aren’t subject to Social Security tax.

If your business has employees, you may need to budget for additional payroll costs, especially if you have many high earners.

Social Security basics

The Federal Insurance Contributions Act (FICA) imposes two taxes on employers, employees and self-employed workers. One is for Old Age, Survivors and Disability Insurance, which is commonly known as the Social Security tax, and the other is for Hospital Insurance, which is commonly known as the Medicare tax.

A maximum amount of compensation is subject to the Social Security tax, but there’s no maximum for Medicare tax. For 2025, the FICA tax rate for employers will be 7.65% — 6.2% for Social Security and 1.45% for Medicare (the same as in 2024).

Updates for 2025

For 2025, an employee will pay:

6.2% Social Security tax on the first $176,100 of wages (6.2% × $176,100 makes the maximum tax $10,918.20), plus
1.45% Medicare tax on the first $200,000 of wages ($250,000 for joint returns, $125,000 for married taxpayers filing separate returns), plus
2.35% Medicare tax (regular 1.45% Medicare tax plus 0.9% additional Medicare tax) on all wages in excess of $200,000 ($250,000 for joint returns, $125,000 for married taxpayers filing separate returns).

For 2025, the self-employment tax imposed on self-employed people will be:

12.4% Social Security tax on the first $176,100 of self-employment income, for a maximum tax of $21,836.40 (12.4% × $176,100), plus
2.90% Medicare tax on the first $200,000 of self-employment income ($250,000 of combined self-employment income on a joint return, $125,000 on a return of a married individual filing separately), plus
3.8% (2.90% regular Medicare tax plus 0.9% additional Medicare tax) on all self-employment income in excess of $200,000 ($250,000 of combined self-employment income on a joint return, $125,000 for married taxpayers filing separate returns).

History of the wage base

When the government introduced the Social Security payroll tax in 1937, the wage base was $3,000. It remained that amount through 1950. As the U.S. economy grew and wages began to rise, the wage base needed to be adjusted to ensure that the Social Security system continued to collect sufficient revenue. By 1980, it had risen to $25,900. Twenty years later it had increased to $76,200 and by 2020, it was $137,700. Inflation and wage growth were key factors in these adjustments.

Employees with more than one employer

You may have questions about employees who work for your business and have second jobs. Those employees would have taxes withheld from two different employers. Can the employees ask you to stop withholding Social Security tax once they reach the wage base threshold? The answer is no. Each employer must withhold Social Security taxes from an employee’s wages, even if the combined withholding exceeds the maximum amount that can be imposed for the year. Fortunately, the employees will get a credit on their tax returns for any excess withheld.
