23 Small Business Tax Deductions to Take Advantage of in 2026
Small business tax deductions reduce your taxable income by letting you write off ordinary and necessary business expenses. From home office costs to retirement contributions, knowing which deductions you qualify for, and keeping good records, can save you thousands at tax time.
Tax deductions are one of the best tools you have for keeping more money in your business. Every legitimate expense you write off lowers your taxable income, which means you pay less to the IRS and have more cash available for payroll, inventory, or growth.
But here's the thing: you can't just wing it at tax time. Maximizing small business tax deductions takes organization, decent recordkeeping, and actually knowing what you can claim. Whether you're a sole proprietor, LLC, or corporation, staying on top of expenses year-round means you won't miss out when it's time to file.
What Is a Small Business Tax Deduction?
A tax deduction is a business expense you subtract from your gross income to lower what you owe in small business taxes. To qualify, an expense needs to be ordinary (normal for your industry) and necessary (actually useful for running your business).
Deductions work differently than tax credits. Deductions reduce your taxable income — so if you're in the 24% tax bracket and deduct $10,000, you save $2,400. Credits reduce your actual tax bill dollar-for-dollar. Both are valuable, just in different ways.
The catch? You need documentation. Without receipts, invoices, or mileage logs, you could lose deductions in an audit or end up overpaying because you forgot what you spent.
Small Business Tax Deductions Checklist: Tried and True + Lesser-Known
Here's a rundown of the most common deductions, plus a few you might not know about.
1. Rent and Mortgage Interest
What it is: If you rent commercial space or own your business property, you can deduct rent payments or the interest portion of your mortgage.
Who qualifies: Any business paying for office, retail, warehouse, or other operational space.
What expenses are deductible:
- Monthly rent payments
- Mortgage interest on commercial property (not the principal)
- Property taxes on business real estate
How the deduction works: Deduct the full rent amount paid during the year. For mortgages, only the interest portion counts — your lender's year-end statement breaks this down.
What you need to document: Lease agreement, rent receipts or canceled checks, Form 1098 showing mortgage interest, property tax bills.
Common mistakes to avoid: Deducting mortgage principal or trying to claim personal residence costs without properly documenting a home office.
Pro tip: If you move from a home office to commercial space mid-year, track both separately so you don't leave money on the table.
2. Home Office Deduction
What it is: A write-off for using part of your home exclusively and regularly for business.
Who qualifies: Self-employed folks or business owners who use a dedicated area in their home as their main place of business.
What expenses are deductible:
Portion of rent or mortgage interest
Utilities
Homeowners or renters insurance
Repairs and maintenance in the office area
How the deduction works: You've got two options. The simplified method gives you $5 per square foot up to 300 square feet. The actual expense method calculates your deduction based on what percentage of your home is used for business.
What you need to document: Measurements or floor plan, photos of your workspace, utility bills, home-related receipts.
Common mistakes to avoid: Claiming a space you also use for personal stuff, like a guest bedroom or kitchen table.
Pro tip: Run the numbers both ways. The simplified method is easier, but depending on your expenses, the actual method might save you more.
3. Home Office Internet and Phone
What it is: Your internet and phone bills, as long as they're legitimately used for business.
Who qualifies: Business owners using these services for work, especially if you have a home office.
What expenses are deductible:
Business phone line or cell plan
Internet service
Business long-distance calls
How the deduction works: If it's 100% business use, deduct the full amount. If you share with family, calculate the business percentage.
What you need to document: Monthly bills, call logs for business use, notes on how you calculated your percentage.
Common mistakes to avoid: Claiming 100% of a family plan without documentation, or trying to write off your teenager's streaming habits.
Pro tip: A separate business line makes this clean and simple — no calculating percentages, just deduct the whole bill.
4. Office Repair and Maintenance
What it is: Costs to keep your business property and equipment in working order.
Who qualifies: Anyone who owns or leases space and needs to maintain it.
What expenses are deductible:
HVAC repairs
Plumbing and electrical fixes
Painting
Equipment tune-ups and service contracts
How the deduction works: Deduct repairs in full the year you pay for them. Major improvements that add value — like a new roof or renovation — get depreciated over time instead.
What you need to document: Contractor invoices, receipts, work orders describing what was done.
Common mistakes to avoid: Confusing repairs (deductible now) with improvements (depreciated over years). Fixing a broken sink is a repair. Remodeling the entire bathroom is an improvement.
Pro tip: Keep notes about what each expense was for so you don't have to figure it out months later at tax time.
5. Business Insurance Premiums
What it is: Insurance premiums that protect your business operations.
Who qualifies: Any business carrying commercial insurance.
What expenses are deductible:
General liability
Professional liability (errors and omissions)
Property and casualty
Business interruption
Workers' compensation
How the deduction works: Deduct premiums paid during the tax year for policies covering business risks.
What you need to document: Policy documents, premium receipts, proof the coverage is for business purposes.
Common mistakes to avoid: Trying to deduct personal life insurance or mixing up health insurance (which has its own rules).
Pro tip: Review your coverage annually. Overpaying for insurance you don't need costs you twice — once in premiums and again in wasted deductions.
6. Bank Fees and Business Interest
What it is: Fees and interest on business accounts and loans.
Who qualifies: Any business with a bank account, credit card, or financing.
What expenses are deductible:
Monthly account fees
Wire transfers and transaction fees
Interest on business loans, lines of credit, or credit cards
Credit card processing fees
How the deduction works: Deduct all fees and interest paid during the year on business financial accounts.
What you need to document: Bank statements, loan documents, credit card statements showing business purchases.
Common mistakes to avoid: Mixing personal and business accounts, or claiming interest on loans used for personal expenses.
Pro tip: There's a real tax advantage of business loans — interest payments reduce your taxable income, making financing less expensive than it looks on paper.
7. Startup Costs
What it is: Money spent getting your business off the ground before you officially opened.
Who qualifies: New businesses in their first year, or established businesses launching something new.
What expenses are deductible:
Market research
Pre-launch advertising
Employee training before opening
Legal and accounting fees for formation
Licenses and permits
How the deduction works: You can deduct up to $5,000 in startup costs your first year (this drops if you spent over $50,000 total). The rest gets spread over 15 years.
What you need to document: Receipts dated before you started operating, notes explaining how each expense relates to starting the business.
Common mistakes to avoid: Claiming personal expenses or costs from after you opened your doors.
Pro tip: Track everything from day one. Early research, planning meetings, and setup costs add up fast, and most people forget about them by tax time.
8. Retirement Contributions (IRA)
What it is: Money you put into retirement accounts as a self-employed person or business owner.
Who qualifies: Self-employed individuals, sole proprietors, and owners contributing to SEP-IRAs, SIMPLE IRAs, or solo 401(k)s.
What expenses are deductible:
SEP-IRA contributions (up to 25% of compensation)
SIMPLE IRA contributions
Solo 401(k) contributions (employee and employer portions)
How the deduction works: Contributions lower your taxable income. Contribution limits vary by plan type and get adjusted by the IRS each year.
What you need to document: Plan documents, contribution receipts, Form 5498 from your account custodian.
Common mistakes to avoid: Contributing more than the annual limit or missing the deadline (usually your tax filing date including extensions).
Pro tip: Max this out if you can — it cuts your current tax bill while building your retirement savings.
9. Auto and Vehicle Expenses
What it is: Costs for using your vehicle for business driving.
Who qualifies: Business owners who drive for work — client visits, deliveries, supply runs, job sites.
What expenses are deductible:
Or actual expenses: gas, maintenance, insurance, depreciation, lease payments
Parking and tolls for business trips
How the deduction works: Pick either standard mileage or actual expenses — you can't use both. Standard is simpler. Actual might be better if you drive an expensive vehicle.
What you need to document: Detailed mileage log with date, destination, purpose, and miles. For actual expenses, keep all receipts and calculate your business-use percentage.
Common mistakes to avoid: No mileage log (this kills the deduction in an audit), or claiming your regular commute to your main office.
Pro tip: Use a mileage app. Automatic tracking beats trying to recreate six months of driving from memory.
10. Business Travel
What it is: Travel expenses when you're away from home overnight for business.
Who qualifies: Business owners traveling for conferences, client meetings, site visits, or other work.
What expenses are deductible:
Flights, trains, buses
Hotels
Rental cars and local transportation
50% of meals while traveling
Baggage fees and tips
How the deduction works: Deduct 100% of travel and lodging, plus half your meal costs. The trip needs to be primarily for business — more than half your time should be work-related.
What you need to document: All receipts, itinerary showing business purpose, conference materials or meeting agendas.
Common mistakes to avoid: Claiming a vacation as business, or not properly splitting costs when you extend a work trip for personal time.
Pro tip: If you tack on vacation days, only deduct expenses for the business portion. Prorate shared costs like airfare based on business versus personal days.
11. Meals and Entertainment
What it is: Business meals with clients, partners, or employees.
Who qualifies: Any business owner having meals with a legitimate business purpose.
What expenses are deductible:
50% of meals during business meetings or travel
100% of employee meals you provide for your convenience (like working lunches)
Office snacks and coffee
How the deduction works: You typically get 50% of qualifying meal costs. Note that entertainment — sporting events, concerts — isn't deductible anymore under current tax law.
What you need to document: Itemized receipts, who attended, what you discussed, the business relationship.
Common mistakes to avoid: Trying to deduct entertainment (not allowed), or forgetting to note the business purpose.
Pro tip: Jot notes on receipts right away — who was there, what you talked about. Saves you from guessing later.
12. Charitable Contributions
What it is: Donations your business makes to qualified charities.
Who qualifies: C-corporations deduct contributions directly. If you're an LLC, S-corp, or sole proprietor, you usually take the deduction on your personal return.
What expenses are deductible:
Cash donations to 501(c)(3) organizations
Fair market value of donated inventory or equipment
Some sponsorships with charitable components
How the deduction works: C-corps can deduct up to 10% of taxable income. Pass-through entities flow donations to owners' personal returns with AGI-based limits.
What you need to document: Donation receipts, acknowledgment letters from charities, appraisals for large non-cash donations.
Common mistakes to avoid: Donating to non-qualified organizations, or skipping the required written acknowledgment for gifts over $250.
Pro tip: Local sponsorships can be good PR and potentially deductible — just make sure the organization qualifies.
13. Education and Professional Development
What it is: Training and courses that maintain or improve skills for your current business.
Who qualifies: Business owners pursuing education directly related to their existing work.
What expenses are deductible:
Industry conferences and seminars
Online courses and workshops
Professional certifications and renewals
Business books and trade publications
How the deduction works: Deduct the full cost if the education improves skills you're already using. Training to enter a completely new field generally doesn't qualify.
What you need to document: Registration receipts, course descriptions, proof it relates to your current business.
Common mistakes to avoid: Claiming general education (like getting an MBA) that qualifies you for a new career rather than improving current skills.
Pro tip: Conferences are great — you can deduct the sessions, travel, and business meals with people you meet there.
14. Accounting and Tax Preparation Fees
What it is: What you pay CPAs, bookkeepers, and tax pros for business services.
Who qualifies: Any business using professional help for accounting, taxes, or financial consulting.
What expenses are deductible:
Business tax return preparation
Bookkeeping and payroll services
Tax planning and consulting
Audit help and representation
How the deduction works: Deduct fees for business-related services. Personal tax prep isn't deductible (unless you're self-employed filing Schedule C).
What you need to document: Invoices showing what services were provided, breakdowns separating business from personal if needed.
Common mistakes to avoid: Claiming personal tax prep fees, or not separating business from personal when you pay for both.
Pro tip: Good accounting pays for itself — professionals catch deductions you'd miss and keep you out of trouble.
15. Marketing and Advertising
What it is: Money spent promoting your business.
Who qualifies: Any business doing marketing or advertising.
What expenses are deductible:
Online ads (Google, Facebook, LinkedIn, etc.)
Print advertising
Radio and TV spots
Website costs
Business cards, brochures, promotional materials
Social media management
How the deduction works: Deduct 100% of advertising expenses in the year you spend them.
What you need to document: Invoices from agencies or ad platforms, campaign reports, receipts for materials.
Common mistakes to avoid: Mixing up marketing expenses with capital improvements, or not tracking which campaigns actually work.
Pro tip: Track ROI on every channel. Deductible or not, you want to spend money on marketing that brings in customers.
16. Professional Services
What it is: Fees for consultants, contractors, and specialists you hire.
Who qualifies: Any business bringing in outside expertise.
What expenses are deductible:
Legal fees
Business consultants
IT support and cybersecurity
Graphic design and branding
Freelance writers and content creators
How the deduction works: Deduct fees paid for business services during the tax year.
What you need to document: Service contracts, detailed invoices, proof of payment, Form 1099-NEC if you paid someone $600 or more.
Common mistakes to avoid: Forgetting to issue 1099s (which can cost you penalties), or trying to deduct personal legal fees.
Pro tip: Collect W-9 forms from contractors upfront. Makes year-end 1099 filing way easier.
17. Health Insurance Premiums
What it is: Health insurance premiums for yourself and your family if you're self-employed.
Who qualifies: Self-employed people and S-corp owners with more than 2% ownership who aren't eligible for a spouse's employer plan.
What expenses are deductible:
Medical and dental insurance
Qualified long-term care insurance
Medicare premiums if you're self-employed
How the deduction works: Self-employed folks deduct premiums on Form 1040, which lowers your adjusted gross income (it's not a business expense on Schedule C).
What you need to document: Insurance documents, premium payment records, proof you were self-employed and couldn't get employer coverage elsewhere.
Common mistakes to avoid: Claiming this if you could have gotten on a spouse's plan, or putting it in the wrong spot on your return.
Pro tip: This is a big deduction if you qualify — it reduces both income tax and self-employment tax.
18. Licensing and Permit Fees
What it is: What you pay to stay legal and licensed.
Who qualifies: Any business that needs licenses, permits, or certifications to operate.
What expenses are deductible:
Business license fees
Professional license renewals
Industry permits (health department, building, liquor, etc.)
Regulatory compliance fees
How the deduction works: Deduct annual or recurring fees in full the year you pay them. Multi-year licenses might need to be spread out.
What you need to document: License certificates, payment receipts, renewal notices.
Common mistakes to avoid: Forgetting about annual renewals, or missing the deduction because you didn't track it.
Pro tip: Set reminders for renewals — staying licensed avoids fines and ensures you get the deduction.
19. Office Relocation and Moving Expenses
What it is: Costs to move your business to a new location.
Who qualifies: Businesses relocating their office, warehouse, or retail space.
What expenses are deductible:
Professional movers
Truck rental and fuel
Packing supplies
Short-term storage
Utility connection fees
How the deduction works: Deduct expenses directly related to moving business property and equipment. Personal moving costs aren't deductible under current rules.
What you need to document: Moving company invoices, rental agreements, storage receipts, proof of the new location.
Common mistakes to avoid: Mixing personal and business moves, or not keeping clear records of what was business-related.
Pro tip: Time your move strategically near year-end if possible to maximize the current-year deduction.
20. Office Supplies and Software
What it is: Everyday materials and tech you need to operate.
Who qualifies: Pretty much every business.
What expenses are deductible:
Office supplies (pens, paper, folders, etc.)
Printer ink and toner
Software subscriptions (accounting, CRM, project management)
Computer equipment under $2,500 (or depreciate larger purchases)
Postage and shipping materials
How the deduction works: Supplies get deducted in full when purchased. Software subscriptions are operating expenses. Expensive equipment might need to be depreciated.
What you need to document: Purchase receipts, subscription confirmations, proof of business use.
Common mistakes to avoid: Claiming personal supplies, or not separating equipment (which might need depreciation) from consumables.
Pro tip: Bulk-buying supplies before year-end can accelerate deductions if you've got cash flow to spare.
21. Payroll and Contractor Expenses
What it is: What you pay employees and contractors.
Who qualifies: Any business with workers.
What expenses are deductible:
Employee wages and salaries
Bonuses and commissions
Employer payroll taxes (your share of Social Security and Medicare)
Contractor payments
Employee benefits like health insurance and retirement contributions
How the deduction works: Deduct total compensation paid during the tax year. Remember to issue W-2s to employees and 1099-NECs to contractors paid $600+.
What you need to document: Payroll records, tax deposit receipts, W-2s, 1099s.
Common mistakes to avoid: Misclassifying employees as contractors (big IRS red flag), or forgetting 1099s.
Pro tip: Use payroll software. It handles calculations, filings, and compliance automatically.
22. Bad Debt
What it is: Money customers owe you that you'll never collect.
Who qualifies: Businesses using accrual accounting who already counted unpaid invoices as income.
What expenses are deductible:
Unpaid customer invoices you've tried to collect
Defaulted loans you made to other businesses
Bounced checks
How the deduction works: Write off the debt once you've made reasonable collection attempts and determined it's worthless. Cash-basis taxpayers usually can't claim this since they never reported it as income.
What you need to document: Original invoices, collection letters and calls, notes showing why it's uncollectible.
Common mistakes to avoid: Writing off debt too quickly, or trying to claim it when you're on cash-basis accounting.
Pro tip: Better to prevent bad debt than deduct it. Clear payment terms and follow-up save you headaches.
23. Depreciation on Equipment
What it is: Writing off big-ticket assets over their useful life.
Who qualifies: Businesses buying equipment, machinery, vehicles, or property that'll last more than a year.
What expenses are deductible:
Computers and electronics
Machinery and equipment
Furniture and fixtures
Business vehicles
Buildings and major improvements
How the deduction works: Spread the cost over the asset's useful life (usually 3-7 years for equipment). Or use Section 179 to deduct up to $1,220,000 immediately (check 2026 limits), or bonus depreciation.
What you need to document: Purchase receipts, date you started using it, business-use percentage for mixed-use items.
Common mistakes to avoid: Forgetting to claim depreciation, or not taking advantage of Section 179 when you need the deduction now.
Pro tip: Accelerated depreciation can slash your current-year taxes if you've bought equipment. Talk to your accountant about timing.
What You Cannot Deduct
Not everything counts as a business expense. Here's what the IRS won't let you write off:
Personal expenses — Your groceries, personal clothes, family vacations
Commuting — Driving from home to your regular office (though business travel between locations is fine)
Fines and penalties — Parking tickets, IRS penalties, regulatory violations
Political contributions — Donations to candidates or parties
Entertainment — Sporting events, concerts, theater (even for clients — this changed a few years ago)
Club dues — Country clubs, social clubs, gyms (unless directly business-related)
Personal life insurance — Premiums where you're the beneficiary
How to Maximize Your Small Business Tax Deductions
Getting the most from deductions takes some discipline:
Keep business and personal separate — Use dedicated business accounts and credit cards. Makes tracking way easier.
Track expenses all year — Don't wait until tax season. Use accounting software or at least keep organized records.
Work with a tax pro — CPAs know current rules and can spot deductions you'd never think of.
Plan big purchases — If you're buying equipment, time it right to maximize Section 179 or bonus depreciation.
File on time — Late filing triggers penalties and interest, and can get you in trouble with the IRS
Using Financing to Manage Tax Season
Tax season can squeeze your cash flow hard, especially when deductions don't wipe out your entire bill. Waiting on customer payments or locking up capital for quarterly estimates can slow you down when you need to move fast. Flexible working capital gives you room to breathe — whether you need to cover tax payments, invest in growth, or smooth out seasonal dips.
Fora Financial offers fast, flexible funding designed for small businesses that can't afford to wait.
