The One Big Beautiful Bill Act (OBBBA), signed into law July 4, 2025, extends or enhances many tax breaks for businesses. But the legislation terminates several business-related clean energy tax incentives earlier than scheduled. For example, the Qualified Commercial Clean Vehicle Credit (Section 45W) had been scheduled to expire after 2032. Under the OBBBA, it’s available only for vehicles that were acquired on or before September 30, 2025. For other clean energy breaks, businesses can still take advantage of them if they act soon.

Deduction for energy-efficient building improvements

The Section 179D deduction allows owners of new or existing commercial buildings to immediately deduct the cost of certain energy-efficient improvements rather than depreciate them over the 39-year period that typically applies. The OBBBA terminates the Sec. 179D deduction for property beginning construction after June 30, 2026.

Besides commercial building owners, eligible taxpayers include:

Tenants and real estate investment trusts (REITs) that make qualifying improvements, and
Certain designers — such as architects and engineers — of government-owned buildings and buildings owned by nonprofit organizations, religious organizations, tribal organizations, and nonprofit schools or universities.

The Sec. 179D deduction is available for new construction as well as additions to or renovations of commercial buildings of any size. (Multifamily residential rental buildings that are at least four stories above grade also qualify.) Eligible improvements include depreciable property installed as part of a building’s interior lighting system, HVAC and hot water systems, or the building envelope.

To be eligible, an improvement must be part of a plan designed to reduce annual energy and power costs by at least 25% relative to applicable industry standards, as certified by an independent contractor or licensed engineer. The base deduction is calculated using a sliding scale, ranging from 50 cents per square foot for improvements that achieve 25% energy savings to $1 per square foot for improvements that achieve 50% energy savings.

Projects that meet specific prevailing wage and apprenticeship requirements are eligible for bonus deductions. Such deductions range from $2.50 per square foot for improvements that achieve 25% energy savings to $5 per square foot for improvements that achieve 50% energy savings.

Other clean energy tax breaks for businesses

Here are some additional clean energy breaks affected by the OBBBA:

Alternative Fuel Vehicle Refueling Property Credit (Section 30C). The OBBBA eliminates the credit for property placed in service after June 30, 2026. (The credit had been scheduled to sunset after 2032.) Property that stores or dispenses clean-burning fuel or recharges electric vehicles is eligible. The credit is worth up to $100,000 per item (each charging port, fuel dispenser or storage property).

Clean Electricity Investment Credit (Section 48E) and Clean Electricity Production Credit (Section 45Y). The OBBBA eliminates these tax credits for wind and solar facilities placed in service after 2027, unless construction begins on or before July 4, 2026. Wind and solar projects begun after that date must be put in service by the end of 2027.

Advanced Manufacturing Production Credit (Section 45X). Under the OBBBA, wind energy components won’t qualify for the credit after 2027. The legislation also modifies the credit in other ways. For example, it adds “metallurgical coal” suitable for the production of steel to the list of critical minerals. And, for critical materials other than metallurgical coal, the credit will now phase out from 2031 through 2033. The credit for metallurgical coal expires after 2029.

Many of these clean energy breaks are disappearing years earlier than originally scheduled, leaving limited time for businesses to act.

If you have employees who travel for business, you know how frustrating it can be to manage reimbursements and the accompanying receipts for meals, hotels and incidentals. To make this process easier, consider using the “high-low” per diem method. Instead of tracking every receipt, your business can reimburse employees using daily rates that are predetermined by the IRS based on whether the destination is a high-cost or low-cost location. This saves time and reduces paperwork while still ensuring compliance. In Notice 2025-54, the IRS announced the high-low per diem rates that became effective October 1, 2025, and apply through September 30, 2026.

How the per diem method works

The per diem method provides fixed travel per diems rather than requiring employees to save every meal receipt or hotel bill. Employees simply need to document the time, place and business purpose of their trip. As long as reimbursements don’t exceed the applicable IRS per diem amounts, they aren’t treated as taxable income to the employee and don’t require income or payroll tax withholding.

Under the high-low method, the IRS establishes an annual flat rate for certain areas with higher costs. All locations within the continental United States that aren’t listed as “high-cost” are automatically considered “low-cost.” The high-low method may be used in lieu of the specific per diem rates for business destinations. Examples of high-cost areas include Boston and Los Angeles. But many locations are considered high-cost during only part of the year. Some of these partial-year locations are resort areas, while others are major cities where costs may be lower for, say, some of the colder months of the year, such as New York City and Chicago.

Under some circumstances — for example, if an employer provides lodging or pays the hotel directly — employees may receive a per diem reimbursement only for their meals and incidental expenses. There’s also a $5 incidental-expenses-only rate for employees who don’t pay or incur meal expenses for a calendar day (or partial day) of travel.

The new high-low per diems

For travel after September 30, 2025, the per diem rate for high-cost areas within the continental United States is $319. This consists of $233 for lodging and $86 for meals and incidental expenses. For all other areas within the continental United States, the per diem rate is $225 for travel after September 30, 2025 ($151 for lodging and $74 for meals and incidental expenses).

For travel during the last three months of 2025, employers must continue to use the same reimbursement method for an employee as they used during the first nine months of the calendar year. Also, note that per diem rates can’t be paid to individuals who own 10% or more of the business.

Revisit reimbursement methods

As the beginning of a new year approaches, it’s a good time to review how your business reimburses employees’ business travel expenses. Switching from an actual expense method to a per diem method in 2026 could save your business and your employees time and frustration. Contact us if you have questions about efficient and tax-compliant travel reimbursement methods.

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.

A major tax change is here for businesses with research and experimental (R&E) expenses. On July 4, 2025, the One Big Beautiful Bill Act (OBBBA) reinstated the immediate deduction for U.S.-based R&E expenses, reversing rules under the Tax Cuts and Jobs Act (TCJA) that required businesses to capitalize and amortize these costs over five years (15 years for research performed outside the United States).

Making the most of R&E tax-saving opportunities

The immediate domestic R&E expense deduction generally is available beginning with eligible 2025 expenses. It can substantially reduce your taxable income, but there are strategies you can employ to make the most of R&E tax-saving opportunities:

Apply the changes retroactively. If you qualify as a small business (average annual gross receipts of $31 million or less for the last three years), you can file amended returns for 2022, 2023 and/or 2024 to claim the immediate R&E expense deduction and potentially receive a tax refund for those years. The amended returns must be filed by July 4, 2026.

Accelerate remaining deductions. Whatever the size of your business, if you began to amortize and capitalize R&E expenses in 2022, 2023 and/or 2024, you can deduct the remaining amount either on your 2025 return or split between your 2025 and 2026 returns, rather than continuing to amortize and capitalize over what remains of the five-year period.

Relocate research activities. Consider relocating foreign research activities to the United States. Before the OBBBA, the five-year vs. 15-year amortization period made domestic R&E activities more attractive from a tax perspective. Now the difference between a current deduction and 15-year amortization makes domestic R&E activities even more advantageous tax-wise.

Take advantage of the research credit. A tax deduction reduces the amount of income that’s taxed, while a tax credit reduces the actual tax you owe dollar-for-dollar, providing much more tax savings than a deduction of an equal amount. So consider whether you may be eligible for the tax credit for “increasing research activities.” But keep in mind that the types of expenses that qualify for the credit are narrower than those that qualify for the deduction. And you can’t claim both the credit and the deduction for the same expense.

Divorce is stressful under any circumstances, but for business owners, the process can be even more complicated. Your business ownership interest is often one of your largest personal assets, and in many cases, part or all of it will be considered marital property. Understanding the tax rules that apply to asset division can help you avoid costly surprises.

Tax-free transfers

Most assets — including cash and business ownership interests — can be divided between spouses without triggering federal income or gift taxes. Under this tax-free transfer rule, the spouse receiving the asset assumes its existing tax basis (used to determine gain or loss) and holding period (short-term or long-term).

Example: If you give your spouse the marital home in exchange for keeping 100% of your company stock, the transfer is tax-free. Both the home and the stock retain their original tax basis and holding period for the new owner.

Tax-free treatment applies to transfers made:

Before the divorce is finalized,
At the time of divorce, and
After divorce, if they occur within one year of the marriage ending or within six years if required under the divorce agreement.

Future tax consequences

While transfers may be tax-free at the time, the recipient will owe taxes if he or she later sells an appreciated asset (where fair market value exceeds the tax basis).

For instance, if your ex-spouse receives 48% of your highly appreciated company stock, no tax is due at transfer. However, when he or she sells the stock, your ex will pay any capital gains tax based on your original basis and holding period.

Important: Appreciated assets come with built-in tax liabilities, which generally makes them less valuable than an equal amount of cash or non-appreciated property. Always account for taxes when negotiating a divorce settlement.

This rule also applies to ordinary-income assets — such as business receivables, inventory or nonqualified stock options. These can be transferred tax-free, but the recipient will report the income and pay taxes when the asset is sold, collected or exercised.

Valuation and adjustments for tax liabilities

A critical step in a divorce involving a business is determining its value. When valuing a business interest for this purpose, the valuator must understand what’s appropriate under applicable state law and legal precedent because the rules and guidance may vary across jurisdictions. The valuation process may be contentious, especially if one spouse is actively involved in the business and the other isn’t (or will no longer be involved after the divorce is settled). A professional valuation considers tangible assets (including equipment, inventory and property), intangible assets (including intellectual property) and other factors.

Potential tax liabilities are also considered during the valuation process. Examples include deferred taxes on appreciated assets, liabilities from unreported income or cash distributions, and implications from goodwill. These adjustments can significantly affect the business interest’s value and the fairness of the settlement agreement.

Nontax issues

There are a number of issues unrelated to taxes that a divorcing business owner should be prepared to address, including:

Cash flow and liquidity. Divorce settlements may require significant cash outlays — for example, to buy out a spouse’s share of the business or to meet alimony and child support obligations. This can strain the business’s liquidity, especially if the owner must take out loans or sell assets to meet these obligations. We can help assess the impact of these financial demands and develop strategies to maintain healthy cash flow, such as restructuring debt or revisiting budgets.
Privacy and confidentiality. Divorce proceedings may expose sensitive business information. Financial statements, client lists and proprietary data may become part of the public record. Business owners should work with legal and financial advisors to protect confidentiality, possibly through protective orders or sealed filings.

Plan ahead to minimize risk

Divorce can create unexpected tax and financial consequences, especially when dividing business interests and retirement accounts (such as 401(k) accounts and IRAs). The financial stakes are often higher for business owners, making careful planning essential.

We can help you navigate these rules and structure your settlement to minimize tax liabilities while complying with state community property laws. The earlier you address potential tax issues, the better your financial outcome after divorce.

One of the most critical decisions entrepreneurs make when starting or restructuring a business is choosing the right entity type. This choice directly impacts how the business is taxed, the level of administrative complexity and regulatory compliance obligations. While legal liability considerations also matter, we will focus on tax implications. For liability advice, consult a legal professional.

Whether launching a new venture or reassessing your current structure, understanding how each entity is taxed can help you make strategic and compliant decisions. Here’s a brief overview of five entities.

1. Sole proprietorship: Simple with full responsibility

A sole proprietorship is the easiest structure to set up. It’s owned and operated by one person and requires minimal administrative effort. Here are the main features:

Taxation. Income and losses are reported on the owner’s personal tax return on Schedule C of Form 1040. Income is subject to 15.3% federal self-employment tax, and the business itself isn’t taxed separately. The owner may also qualify for a Qualified Business Income (QBI) deduction, potentially reducing the effective tax rate.
Compliance. Aside from obtaining necessary licenses or a business name registration, there’s little required paperwork. However, the owner is personally liable for all business debts and legal obligations.

2. S Corporation: Pass-through entity with payroll considerations

An S corp is a tax designation offering pass-through taxation benefits while imposing stricter rules. Here are the highlights:

Taxation. S corps don’t pay income tax at the entity level. Instead, profits or losses are passed through to shareholders via Schedule K-1 and reported on individual returns. A key tax benefit is that shareholders who are employees receive a salary (subject to payroll tax), while additional profit distributions aren’t subject to self-employment tax. However, the salary must be reasonable. The business is eligible for QBI deductions.
Compliance. To qualify, S corps must have 100 or fewer shareholders, all U.S. citizens or residents, and only one class of stock. They must file Form 2553, issue annual Schedule K-1s and follow corporate formalities like shareholder meetings and recordkeeping. An informational return (Form 1120-S) is also required.

3. Partnership: Collaborative ownership with pass-through taxation

A partnership involves two or more individuals jointly operating a business. Common types include general partnerships, limited partnerships, and limited liability partnerships (LLPs). Here’s what makes it unique:

Taxation. Partnerships are pass-through entities. The business files Form 1065 (an informational return), and income or loss is distributed to partners on Schedule K-1. Partners report this on their personal returns. General partners must pay self-employment tax, while limited partners usually don’t. The business is eligible for QBI deductions.
Compliance. Partnerships require a detailed partnership agreement, coordinated recordkeeping and clear profit-sharing arrangements. While more complex than a sole proprietorship, partnerships offer flexibility for growing businesses.

4. Limited liability company: Flexible and customizable

An LLC merges elements of corporations and partnerships, offering owners — called members — both operational flexibility and liability protection.

Taxation. By default, a single-member LLC is taxed like a sole proprietorship, and a multimember LLC like a partnership. However, LLCs may elect to be taxed as a C or S corp by filing Form 8832 or Form 2553. This gives owners control over their tax strategies. LLCs that don’t elect C corp status are eligible for QBI deductions.
Compliance. LLCs require articles of organization and often must have an operating agreement. Though not as complex as corporations, they still generally face state-specific compliance requirements and annual filings.

5. C Corporation: Double taxation with scalability

A C corp is a distinct legal entity offering the most liability protection and growth potential through stock issuance. Here are its features:

Taxation. C corps face double taxation — the business pays taxes on earnings (currently at a 21% federal rate), and shareholders pay taxes again on dividends. However, C corps can offer deductible benefits (for example, health insurance, retirement plans) and retain earnings without immediately distributing profits. C corps aren’t eligible for QBI deductions.
Compliance: These entities require the most administrative upkeep, including bylaws, annual meetings, board minutes, and extensive state and federal reporting. C corps are ideal for companies seeking venture capital or IPOs.

After hiring employees

Regardless of entity type, adding employees increases compliance requirements. Businesses must obtain an Employer Identification Number (EIN) and withhold federal and state payroll taxes. Employers also take on added responsibilities related to benefits, tax deposits, and employment law compliance.

What’s right for you?

There’s no universal answer to which entity is best. The right choice depends on your growth goals, ownership structure and financial needs. Tax optimization is a critical factor. For example, an LLC electing S corp status may help minimize self-employment taxes if set up properly. Contact us. We can coordinate with your attorney to ensure your structure supports both your tax strategies and business goals.

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.
