This checklist was built with Scott Leitner, PHR, CPP, MBA, our Senior Manager of Payroll Operations. Scott is a Certified Payroll Professional (CPP), which is the gold standard credential in the payroll field, and he's spent 18 years helping small and midsize businesses get payroll right, including hundreds of employer transitions at ADP before joining Homebase.

The insights here reflect what we see across 100,000+ small businesses running payroll through Homebase. Specifically, the documentation gaps that cause hourly-team owners to miss deductions they're legally owed. We know where the money gets left on the table, because we see it happen.

One important note: this is not tax advice. For your specific situation, work with a CPA.

A tax deduction reduces your taxable income, which lowers the amount you owe in taxes. Tax deductions for small business are expenses the IRS allows you to subtract from your revenue before calculating what you owe.

Expenses must be both "ordinary and necessary":

A salon can deduct scissors and styling products. A plumber can deduct pipe wrenches and service vehicle costs.

Here's how it works:

If you earn $100,000 and deduct $20,000 in qualified expenses, you're only taxed on $80,000. At a 22% tax rate, that saves you $4,400.

Knowing what can be deducted from taxes starts with the IRS's ordinary-and-necessary standard, laid out in Publication 535 (Business Expenses). When in doubt, check there or talk to your accountant.

This business tax deductions list covers all 21 categories the IRS recognizes for small businesses, from startup costs to retirement contributions. Whether you call them small business write offs or deductions, they all reduce the same thing: your taxable income. 

Think of it as your master tax write offs list and tax deductible expenses list in one, with examples of tax write offs across every category a small business owner encounters. Track what you spend throughout the year, not just at filing time.

You can deduct up to $5,000 in startup expenses in your first year of business. Qualifying costs include legal fees, permits, market research, website development, and initial advertising: anything an established business would normally deduct, incurred before you officially opened.

Some small businesses can deduct up to 20% of their qualified business income from their taxes. This deduction applies to pass-through entities like sole proprietorships, partnerships, S corporations, and LLCs, which is why the QBI deduction tops nearly every LLC tax deductions list. Your QBI is essentially your net profit, excluding capital gains, dividends, and interest income.

This is one of the most valuable deductions you can claim. Income limits apply, so confirm eligibility with your tax professional.

If you use a vehicle solely for business, you can deduct 100% of operating costs , fuel, maintenance, registration, insurance, lease payments, and depreciation.

If you use your personal vehicle for business, you have two options:

Standard mileage rate: Multiply your business miles by the IRS mileage rate (72.5 cents per mile January–June 2026; 76 cents per mile July–December 2026, following a mid-year adjustment). Actual expense method: Track real costs like gas, oil, repairs, and insurance, then deduct your business-use percentage. You can't switch between methods for the same vehicle.

Rent, security deposits, and lease cancellation fees for office or retail space are fully deductible:

Cash or in-kind donations to 501(c)(3) organizations are tax deductible. The IRS sets limits based on your adjusted gross income. Sole proprietors, partners, and LLC owners must claim charitable donations on their personal return, not their business return.

Pens, paper, printer ink, staplers, business software subscriptions, computers, phones, and office furniture all qualify.

Key distinction:

Cloud software subscriptions like project management tools, accounting software, and communication platforms count as office supplies and are fully deductible in the year you pay for them.

Depreciation lets you spread the cost of expensive assets over several years:

For 2026, you can deduct up to $2,560,000 in depreciation for qualifying assets under Section 179. Bonus depreciation at 100% is also available for new equipment acquired after January 19, 2025. Work with your accountant on this one, because depreciation rules get complicated fast.

Fees for attorneys, accountants, bookkeepers, tax preparers, and business consultants are fully deductible as long as the services relate to your business. If you paid a lawyer to handle a personal matter, that's not deductible.

Your website, social media ads, print flyers, local event sponsorships, business cards, SEO services, email marketing tools, and promotional materials are all deductible. You can write off 100% of advertising and marketing expenses up to $5,000 in the tax year.

Salaries, hourly wages, bonuses, commissions, sick time, vacation pay, and health insurance for employees are all deductible. This applies to businesses that employ people other than the owner , sole proprietors can't deduct their own salary, but they can deduct what they pay employees.

Also deductible:

Homebase Payroll automatically tracks wages, overtime, PTO accruals, and tips , making this deduction category simple to document and export come tax time.

When a customer owes you money and there's no realistic way to collect, that debt becomes "worthless" and you can write it off. The debt must have been included in your gross income first. If you use cash-basis accounting and never received payment, it was never counted as income and can't be deducted.

Webinars, certifications, industry books, conferences, trade shows, and professional association memberships are deductible if they maintain or improve skills for your current business. They can't qualify you for a new trade entirely.

Workers' compensation, general liability, professional liability, business property insurance, unemployment insurance, and health insurance for employees are all deductible. If you're self-employed, you may also deduct health insurance premiums for yourself and your family on your personal return.

You can deduct interest paid on business loans, business credit cards, and lines of credit. Only the interest portion qualifies, not the principal. Credit card processing fees (like Square or Stripe fees) are also deductible, though they fall under merchant services.

Client meetings over lunch, team celebrations, and meals while traveling for business are generally 50% deductible. Meals provided to employees for the employer's convenience (like working lunches during mandatory meetings or overtime dinners) were 50% deductible through 2025.

Important 2026 change: Starting January 1, 2026, on-site employer-provided meals (breakroom coffee, cafeteria meals, on-site dining) are no longer deductible. Business meals with clients and meals during travel remain 50% deductible. Entertainment expenses are not deductible.

Business phone plans, mobile devices, and internet service are deductible. For personal devices used partly for business, deduct only the business-use percentage. Track a typical month to calculate a reasonable figure.

For product-based businesses, inventory costs are deductible as part of your cost of goods sold (COGS).

What counts as inventory costs:

Value your inventory at the start and end of each tax year to calculate COGS accurately.

Monthly account maintenance fees, overdraft charges, wire transfer fees, and check printing costs for your business bank account are all deductible.

Also deductible:

You can't deduct bank fees if you're using your personal bank account for business transactions. This is another reason to open a dedicated business account.

Money paid to freelancers, gig workers, and agencies is deductible as long as the contractor isn't actually an employee and the services are for your business. Send Form 1099-NEC to any contractor you pay more than $600 during the tax year.

Contributions to traditional IRAs, Roth IRAs, Solo 401(k)s, SEP-IRAs, SIMPLE IRAs, and Keogh plans are deductible. The amount depends on the plan type and your income level. For self-employed owners, contributions on your own behalf are deductible too.

Flights, train tickets, hotel stays, car rentals, rideshare services, and even dry cleaning while on business trips are deductible.

Requirements for travel deductions:

Keep detailed records of dates, destinations, business purpose, and receipts.

Payroll is typically a small business's largest expense, which makes payroll deductions for small business the most important category to document correctly. But the missed deductions don't stop at wages. Here's the full list of what hourly-team owners leave on the table.

Most owners correctly deduct wages but forget the employer's share of FICA: 6.2% Social Security and 1.45% Medicare on every employee's wages. These costs are fully deductible.

Key 2026 figures to track:

What this adds up to in practice: A restaurant with 10 employees averaging $40,000 in wages owes roughly $30,600 in employer FICA alone. That's a meaningful deductible expense many owners fold into "payroll" without tracking separately, which creates documentation gaps at audit time.

See 2026 payroll tax rates and IRS employment tax guidance for the full picture.

If you employ tipped workers (servers, bartenders, salon team members, hotel workers), you may be eligible for the FICA Tip Credit under IRS Form 8846.

This is a dollar-for-dollar tax credit, not just a deduction, for FICA taxes you paid on tips above the $7.25 per hour federal minimum wage threshold (the rate in effect on July 24, 2009, which is the figure frozen in statute for this credit). It can be worth up to 7.65% of qualifying tips per employee, adding up to thousands in direct tax liability reduction for a restaurant with several full-time tipped team members. It's one of the most underused credits in food service.

Starting with 2026 W-2s (issued January 2027), employers must report qualifying tips in Box 12 (code TP), qualifying overtime premium in Box 12 (code TT), and the Treasury Tipped Occupation Code in Box 14b. Homebase automatically generates the TP and TT entries. See the full W-2 reporting requirements for details.

The no tax on overtime 2026 provision, part of the OBBBA, introduced a personal income tax deduction for employees on qualifying overtime premium, specifically the half-time portion of overtime pay. It's retroactive to January 2025 and applies through 2028.

The basics:

Why your 2025 records matter: For the 2025 tax year, employers weren't required to separately report qualifying overtime. More than 29 million taxpayers still claimed the deduction, averaging $3,100 (Treasury, July 2026), many calculating amounts manually from pay stubs. If your tracking was imprecise, some team members may have underclaimed. Keep those records accessible.

Payroll processing fees, tool subscriptions, and accounting integrations are ordinary business expenses, fully deductible in the year you pay them.

For hourly-team businesses, the tool that processes your payroll also generates the audit-ready records that substantiate every deduction above. Without clean records, documentation gaps create real risk.

Primo Stropoli at Tetta's Market, a fourth-generation retail and food service business in Olive, New York, ran payroll entirely on paper and sticky notes before switching to Homebase. What used to take hours of data entry now takes five minutes a week, with tax forms auto-populated for his accountant. "It's hard to put a number on it, but I'm saving hundreds of hours," Primo says. Read Primo's full story.

Homebase Payroll starts at $39/month plus $6 per active employee, and the subscription itself is a deductible business expense. It auto-tracks wages, overtime, PTO, tips, and employer taxes, and generates the new W-2 Box 12 TP and TT entries your team members need to claim their personal deductions.

If you pay any portion of health insurance premiums for your team members, your employer contribution is fully deductible. This is one that slips through when owners add benefits partway through the year and don't track the premiums they paid before their accounting caught up.

Also deductible: contributions to employee HSAs, FSAs, and group dental and vision plans.

State business income taxes, franchise taxes, local business license fees, health department inspection fees, and sales taxes paid on business purchases are all deductible under IRS Publication 535. These get missed because they're paid at irregular intervals through the year and aren't tied to a regular vendor bill.

Real-world examples: an annual restaurant license, a food handler permit, a retail business registration, a county health inspection , all deductible operating costs. Keep a separate folder or line item in your accounting for tax and license payments so none slip through.

The Work Opportunity Tax Credit was a federal tax credit worth up to $2,400 per eligible new hire from target groups: veterans, long-term unemployed workers, SNAP and SSI recipients, ex-felons, and others. WOTC expired on December 31, 2025, and has not been reauthorized by Congress as of the date of this post. Wages paid to employees who began work on or after January 1, 2026, are not currently eligible.

That said, WOTC has lapsed and been retroactively renewed multiple times since its creation in 1996. Many tax advisors recommend continuing to file IRS Form 8850 with your state labor agency within 28 days of each new hire's start date during the hiatus. If Congress reinstates WOTC retroactively (which has happened in the past), having the paperwork filed protects your ability to claim it.

Monitor updates from the Department of Labor's WOTC program and the IRS for reauthorization news.

Knowing what you can deduct is only half the battle. The other half is claiming those deductions correctly, and that starts with letting go of a fear that costs more than it protects.

Many small business owners are more afraid of deductions than they should be. Tax professionals consistently observe that owners are far more likely to overpay by under-claiming than to attract IRS scrutiny from legitimate deductions. A 30-year CPA in a widely-cited r/tax community discussion noted his clients overpay versus underpay at roughly a 2:1 ratio.

What actually draws attention isn't a well-documented home office or a payroll app subscription. It's implausible patterns:

Document everything you're entitled to. Here's exactly what that looks like:

Every time you spend money on your business, save proof. A phone photo, a QuickBooks scan, a cloud folder: any system works as long as you actually use it.

Don't wait until April to figure out what you spent all year. Assign every expense to a category from this checklist as it happens. If you're using Homebase for payroll, wages, overtime, PTO, and tips are already tracked. Just export the reports.

Small businesses can write off operating costs like rent, employee wages, advertising, inventory, office supplies, insurance, legal fees, and equipment.

The IRS allows deductions for expenses that are "ordinary and necessary," meaning they're common in your industry and helpful for running your business. Check the 21-category checklist above for the complete list.

The best tax deductions small businesses overlook include the QBI deduction (up to 20% of qualified business income), Section 179 depreciation, bad debt write-offs, bank fees, and membership dues.

Many small businesses also forget to track legitimate travel expenses, marketing costs, and home office deductions. These add up to thousands in missed savings.

The $75 rule means the IRS doesn't require physical receipts for business expenses under $75. However, you still must record the amount spent, date, location, and business purpose.

One important exception: lodging always requires a receipt regardless of amount, even for a $60 hotel stay.

As a small business, you can claim expenses like payroll, rent, utilities, legal and accounting fees, insurance premiums, advertising, business software, and equipment purchases. To qualify as deductible, each expense must be ordinary (common in your industry), necessary (helpful for your business), and directly tied to your business operations.

The best tax write-offs for small businesses with hourly employees are wages and employer payroll taxes (including the employer share of FICA), health insurance premiums, workers' compensation, and payroll processing fees. If you operate in food service or hospitality, the FICA Tip Credit (Form 8846) reduces your tax bill dollar-for-dollar, not just your taxable income.

A tax deduction reduces your taxable income, so a $10,000 deduction saves you $2,200 in the 22% bracket. A tax credit reduces your actual tax bill dollar-for-dollar, so a $2,400 credit saves you exactly $2,400 regardless of your rate.

Credits deliver the same savings at every income level. For hourly teams in food service, the most impactful active credit right now is the FICA Tip Credit (Form 8846). WOTC, historically worth up to $2,400 per hire, expired December 31, 2025, and is pending Congressional renewal.

Claiming every small business tax deduction you're entitled to is not risky. Tax professionals consistently find that owners are far more likely to overpay by under-claiming than to draw scrutiny from legitimate deductions.

What draws IRS attention is implausible patterns: round-dollar expenses stacked across categories, persistent losses with no real business activity, or personal expenses not separated from business accounts. Document everything you can defend.
