Many small businesses start out as sole proprietorships. This structure is simple and inexpensive to establish and maintain — and it gives the owner direct access to profits without having to take formal distributions. But it also makes your taxes more complicated than when you were a W-2 employee. Here are some federal tax issues to consider if your business operates as a sole proprietorship.

Reporting income and expenses

You’ll report income and expenses from your business activities on Schedule C of your personal return (Form 1040). The net income will be taxable to you regardless of whether you withdraw cash from the business. Your business expenses are deductible against gross income, not as itemized deductions. If you have losses, they’ll generally be deductible against your other income, subject to special rules related to hobby losses, “excess” business losses incurred by noncorporate taxpayers, passive activity losses and losses from activities in which you weren’t “at risk.”

Sole proprietors may be eligible for certain deductions that generally aren’t available to other individual taxpayers. For instance, you may qualify for an above-the-line self-employed health insurance deduction for premiums paid for medical, dental and qualifying long-term care coverage, subject to certain limitations. This means your deduction for medical insurance won’t be subject to the rule that limits itemized deductions for medical expenses.

In addition, you may be entitled to deduct home office expenses if:

A home office is your principal place of business (including when you perform management or administrative tasks there and have no other fixed place to perform them),
You use your home as a place to meet or deal with customers, clients or patients in the normal course of business, or
You store inventory or product samples at home.

In general, to qualify, the area must be used regularly and exclusively for business purposes.

The home office deduction may include an allocable part of mortgage interest or rent, insurance, utilities, repairs, maintenance and, if you own the home, depreciation. Alternatively, you can use a simplified method based on the square footage of the qualifying space. You may also be able to deduct travel expenses from your home office to another work location.

Be sure to keep complete records of your income and expenses. Proper documentation is needed to claim all the tax breaks to which you’re entitled. Certain expenses, such as automobile, travel, meals, and home office expenses, require extra attention because they’re subject to special recordkeeping rules or deductibility limits.

Claiming the QBI deduction

Another special tax break that you might qualify for as a sole proprietor is the Section 199A qualified business income (QBI) deduction. It generally equals 20% of QBI, not to exceed 20% of taxable income. QBI generally is defined as the net amount of qualified items of income, gain, deduction and loss that are effectively connected with the conduct of a U.S. business. QBI doesn’t include certain investment items or reasonable compensation paid to an owner for services rendered to the business.

This deduction is taken “below the line,” meaning it reduces taxable income, rather than being taken “above the line” against your gross income. However, you can take the QBI deduction even if you don’t itemize deductions and instead claim the standard deduction.

One word of caution: The QBI deduction is subject to additional limits at higher income levels. For 2026, these limitations generally begin to apply when taxable income (calculated before any QBI deduction) exceeds $201,750 ($403,500 for married couples filing jointly). For 2026, these limitations are fully phased in once taxable income exceeds $276,750 ($553,500 for joint filers). Contact us to learn more about the limitations that apply to your situation.

The One Big Beautiful Bill Act (OBBBA) made the QBI deduction permanent. Starting in 2026, the OBBBA also expands the income ranges over which the limitations phase in, potentially allowing larger deductions for some taxpayers. And it provides a new minimum deduction of $400 for taxpayers who materially participate in an active trade or business if they have at least $1,000 of QBI from it. The minimum deduction will be annually adjusted for inflation after 2026.

Paying self-employment taxes

One downside of owning your own business is that you must pay self-employment taxes. These taxes are the equivalent of federal payroll taxes for employees, but self-employed people must pay both the employer’s and employee’s share of them. They’re imposed in addition to income tax, but you can deduct half of your self-employment tax as an adjustment to income.

For 2026, you must pay self-employment tax (Social Security and Medicare) at a 15.3% rate on your net earnings from self-employment up to $184,500, and Medicare tax only at a 2.9% rate on the excess. An additional 0.9% Medicare tax is imposed on self-employment income in excess of $250,000 for joint filers, $125,000 for married taxpayers filing separate returns and $200,000 in all other cases. The additional Medicare tax threshold isn’t adjusted for inflation.

Establishing a tax-advantaged retirement plan

You might also want to consider setting up a qualified retirement plan. The advantages are that amounts contributed to it are deductible at the time of the contributions and aren’t subject to income tax until they’re withdrawn.

One option is a Simplified Employee Pension (SEP) plan, which requires minimal paperwork. You generally can set up a SEP and make deductible contributions for the tax year as late as the due date of your income tax return for the year, including extensions. The contribution amounts are discretionary, and the annual limits are high. But, if you have employees, they generally must be included in the plan, provided they work enough hours and meet other qualification requirements.

If you don’t establish a qualified retirement plan, you may still be able to contribute to a traditional IRA. But your annual contribution limit will generally be significantly lower.

Making quarterly estimated payments

The U.S. tax system is considered “pay as you go.” So, you’ll probably have to make estimated tax payments each quarter. Estimates should include both federal income tax and self-employment taxes. Estimated payments are generally calculated using Form 1040-ES.

Quarterly payments are generally due on April 15, June 15 and September 15 of the current year and January 15 of the following year. If a due date falls on a weekend or legal holiday, the deadline generally moves to the next business day. Paying enough by each deadline is critical; if you fall behind, you’ll likely owe interest and penalties.

Applying for an EIN

Sole proprietors don’t automatically need an employer identification number (EIN). You can generally use your Social Security number for federal tax purposes — unless you hire employees. You might also need an EIN if your business:

Owes employment or excise taxes,
Withholds certain taxes on payments to a nonresident alien,
Establishes certain retirement plans, or
Changes its legal structure, such as incorporating or forming a partnership.

Additionally, you might consider obtaining an EIN voluntarily for banking or administrative purposes. An EIN is available at no cost through the IRS website. To apply, you’ll need to provide identifying information, including a valid Social Security number or other taxpayer identification number, and details about the business. Eligible U.S. applicants generally receive the EIN immediately after completing the online application. You can also submit Form SS-4 by fax or mail.

Businesses in economically distressed communities often have difficulty obtaining capital for expansion, equipment, facilities and other investments. The New Markets Tax Credit (NMTC) encourages private investment in these underserved areas by offering federal income tax credits to qualifying investors.

This credit was previously scheduled to expire on December 31, 2025. However, the One Big Beautiful Bill Act made it permanent. Let’s take a closer look at how this tax break could benefit your small business.

Potential tax and financing benefits

The NMTC is generally available to individuals and businesses that make qualified equity investments in community development entities (CDEs). A CDE is generally a domestic corporation or partnership whose primary mission is to serve low-income communities or provide investment capital to them. To participate in the program, a CDE must be certified by the U.S. Department of the Treasury’s Community Development Financial Institutions Fund.

The CDE then raises funds from investors to use for qualifying loans, equity investments or other approved activities in low-income communities. Your benefits depend on your role in the transaction. If your business invests in a CDE, you may be able to claim the tax credit. If your business receives financing from a CDE, you may benefit indirectly by gaining access to capital or financing terms that might not otherwise be available. For many small business owners, these financing opportunities may be the more relevant aspect of the NMTC program.

Credit amount and filing requirements for investors

The NMTC equals 39% of the investor’s qualified equity investment in the CDE. The credit is claimed over seven years as follows:

5% of the investment in each of the first three years, and
6% in each of the next four years.

So, a qualifying $1 million investment could generate $390,000 in federal tax credits over seven years, subject to applicable limitations.

To claim the credit, you must make a cash investment that the CDE designates as a qualified equity investment. The CDE must use “substantially all” of the funds for qualified low-income community investments (QLICIs). In general, a CDE satisfies this threshold if it invests at least 85% of its aggregate gross assets in QLICIs (reduced to 75% in the seventh year).

The credit is calculated using Form 8874, “New Markets Credit,” and reported as part of the general business credit on Form 3800.

Claiming the NMTC reduces your tax basis in the investment, which may affect the tax consequences of a later sale. In addition, previously claimed credits may be recaptured (with interest) if the CDE fails to meet program requirements or redeems your investment during the seven-year credit period.

Financing benefits for qualifying businesses

By encouraging investment in CDEs, the NMTC may expand access to financing for qualifying businesses and nonprofit organizations in low-income communities. Examples of businesses and projects that may receive NMTC-supported financing are:

Real estate developments,
Manufacturers,
Retailers,
Health care providers,
Child care centers and schools,
Hotels, and
Community centers.

For example, suppose you own a grocery store in a qualifying community and need funds to renovate the building. A CDE could use capital raised from investors to provide your business with a loan or equity financing for this project. In this scenario, qualified investors would receive the federal tax credit, and your business would benefit from access to financing that might otherwise be difficult to obtain through conventional sources.

Simply operating in a low-income area doesn’t automatically qualify a business or project for NMTC-supported financing. The CDE must determine whether the business, location and planned use of the financing satisfy the program’s requirements.

Exploring NMTC opportunities

The now-permanent NMTC may offer a valuable tax break for qualified investors and provide an important source of financing for qualifying businesses and community development projects. However, the rules are complex. Contact us to learn more. We can help you estimate the potential tax or financing benefits and address the applicable compliance requirements.

Your employees use Form W-4, “Employee’s Withholding Certificate,” to tell you how much federal income tax to withhold from their pay. Most forms are routine, but an altered certificate, unusual accompanying statement or IRS lock-in letter may require special handling. Knowing how to respond can help your business meet its withholding obligations without becoming involved in an employee’s personal tax dispute.

Recognizing an invalid form

An employee is responsible for the information provided on Form W-4 and signs the form under penalties of perjury. Businesses generally aren’t required to verify whether the employee’s filing status, credits, deductions or other adjustments are accurate.

However, a Form W-4 may be invalid if the employee:

Alters the official form,
Deletes or crosses out the penalties-of-perjury declaration, or
Indicates that information on the form is false.

You must also reject any substitute form created by an employee. An electronic or substitute form developed by your business may be acceptable if it meets IRS requirements.

If an employee submits an invalid Form W-4, you should explain that you can’t accept it and should request a valid replacement. You can generally continue using any valid Form W-4 already in effect until you receive the replacement. If you don’t have a valid form already on file, withhold as if the employee selected “single or married filing separately” and made no entries in Steps 2, 3 or 4.

Similarly, a claim of exemption from withholding isn’t automatically invalid. Beginning with the 2026 Form W-4, employees claiming exemption from withholding use the exemption checkbox on the form. For 2026, an employee generally may claim exemption only if the employee had no federal income tax liability in 2025 and expects to have none in 2026. The employee — not the employer — is responsible for determining whether those requirements are met.

Responding to IRS instructions

Businesses aren’t required to routinely send Forms W-4 to the IRS. You generally must submit these forms only when directed to do so in a written IRS notice or in specific published guidance.

The IRS uses information reported on Forms W-2 and other records to identify employees who may have inadequate withholding. If the IRS determines that an employee’s withholding needs to be increased, it may send you a “lock-in letter” specifying the filing status and adjustments that must be used. Before these instructions take effect, the employee receives a separate notice and an opportunity to dispute the determination with the IRS.

Once the lock-in instructions take effect, you generally must disregard a Form W-4 that would reduce withholding below the IRS-mandated amount. However, you must honor a new form that results in more withholding. If your business accepts Forms W-4 electronically, its system must prevent an employee subject to a lock-in letter from reducing withholding below the locked-in amount.

An employee who disagrees with a lock-in determination must work directly with the IRS. The employee may submit a new Form W-4 and supporting information to the address provided in the IRS notice. Don’t reduce withholding unless the IRS authorizes the change. Businesses that fail to follow lock-in instructions may be liable for the additional tax that should have been withheld.

Establishing consistent procedures

Your payroll procedures should explain how Forms W-4 are submitted, reviewed and retained. Train payroll personnel to recognize altered or unauthorized forms, but don’t ask them to evaluate whether an employee has calculated the proper amount of withholding. That determination generally belongs to the employee and, when necessary, the IRS.

For questions about completing Form W-4, direct employees to the IRS Tax Withholding Estimator or suggest consulting their personal tax advisors. Avoid giving individualized tax advice unless your business is qualified and authorized to provide it.

Know when to seek assistance

Unusual Forms W-4 and IRS lock-in letters can create compliance risks if they aren’t handled correctly. We can guide you through the withholding rules to help reduce the risk of costly errors.

Offering a broad menu of employee benefits can help your business attract and retain skilled workers. One benefit that’s popular among employees with families is employer-provided child care. Although this option hasn’t been financially feasible for many small businesses, recent tax law changes may give you a reason to reconsider opening (or upgrading) a child care facility, contracting with a child care provider or participating in a jointly operated arrangement. Here’s an overview of the credit and how it’s been enhanced starting in 2026.

Recent changes

Under Section 45F of the tax code, employers may claim a tax credit for eligible expenses paid or incurred to provide child care to employees. For 2026, the credit has increased from 25% to 40% of an employer’s qualified child care facility expenditures, plus 10% of its qualified child care resource and referral expenditures paid or incurred during the tax year. It’s limited to a total of $500,000 per tax year (up from $150,000 for 2025). Beginning in 2027, the $500,000 limit will be adjusted annually for inflation.

The credit has been further enhanced for certain small businesses. If you meet the eligibility requirements, you can claim a credit equal to 50% of qualified child care facility expenses, plus 10% of qualified resource and referral expenditures, up to a maximum of $600,000 for 2026 (annually inflation-adjusted going forward).

Eligible small businesses are generally those that had average annual gross receipts for the previous five tax years below an inflation-adjusted threshold. For 2026, the threshold is $32 million.

Also, eligible small businesses can now pool their resources to provide child care for their employees and to use third-party intermediaries to facilitate child care services. These options may make the credit more accessible to businesses that can’t justify operating their own facilities.

Qualified expenditures

Qualified child care facility expenditures are amounts paid or incurred to:

Acquire, construct, rehabilitate or expand property that’s 1) to be used as part of your qualified child care facility, 2) depreciable or amortizable, and 3) not part of your principal residence or an employee’s home,
Operate your qualified child care facility, including the costs to train and compensate its employees and provide scholarship programs, or
Contract with a qualified child care facility to provide eligible services to your employees.

It’s important to note that qualified child care expenses exclude amounts that exceed the fair market value of providing such care.

A qualified child care facility is one that meets all state and local regulatory requirements. In addition, the facility 1) must be used principally to provide child care (unless it’s also the personal residence of the person who operates it), 2) must be open to all employees during the tax year, and 3) can’t discriminate in favor of highly compensated employees. And, if the facility is your principal trade or business, at least 30% of enrollees must be your employees’ dependents.

Additional rules

To avoid doubling your tax benefits from the same expenditures, your tax basis in any qualified child care facility is reduced by the amount of the credit attributable to facility-related expenditures. You also can’t claim other deductions or credits based on the same expenses.

In addition, if your child care facility ceases to operate as such or undergoes a change in ownership before the tenth tax year after the tax year in which it’s placed in service, you may have to recapture (pay back) some or all of the credit. The percentage of the credit that must be recaptured decreases gradually over the 10-year period.

The Sec. 45F credit is part of the general business credit, which is composed of more than 30 separate tax credits that are subject to combined limits based on your tax liability. So the amount you can use in the current year may be limited. However, any unused credit can generally be carried back one year and carried forward for 20 years. The credit is calculated and claimed on Form 8882, “Credit for Employer-Provided Childcare Facilities and Services.”

Look before you leap

Providing child care for your employees can be a major long-term investment. Although the recent enhancements to the employer-provided child care credit help make this benefit option more feasible, it isn’t right for every employer. You should also consider workforce demographics, operational costs, available providers, and the associated risks and responsibilities. Even when outsourcing, you’ll have to exercise due diligence to select a reputable provider, monitor service quality and make changes as necessary.
