Your 2026 Tax Deduction Checklist: 25 Write-Offs for Families, Freelancers, and Small Businesses

Tax deductions can reduce your taxable income and may help you keep more of your hard-earned money. But a deduction is only helpful when it is legal, properly calculated, and supported by good records.

This tax deduction checklist is designed for the 2026 filing season and covers common deductions and tax-related expenses for families, freelancers, gig workers, and small-business owners.

Tax rules and limits can change. If you are filing a return in 2026 for income earned during 2025, use the forms and instructions for that tax year. If you are planning for income earned during 2026, confirm the rules that apply when you file in 2027.

The basic rules for claiming deductions

Before claiming any write-off, ask:

• Was the expense legally deductible?
• Was it related to earning income or a qualifying personal deduction?
• Was it ordinary and necessary for the business?
• Do you have a receipt, statement, log, or other documentation?
• Did you separate business expenses from personal expenses?

The IRS explains that business records should clearly support your income and expenses. You can review the IRS guidance on recordkeeping and business expense resources.

Not every deduction applies to every taxpayer. Some personal deductions require itemizing instead of taking the standard deduction. Business deductions may be reported differently depending on whether you operate as a sole proprietor, partnership, corporation, or another entity.

Family and individual deduction checklist

These expenses may apply to working individuals and families. Some are deductions, while others may support a tax credit or another tax benefit.

1. Mortgage interest

If you own a qualifying home and itemize deductions, mortgage interest may be deductible within applicable limits. Keep your mortgage interest statement, usually Form 1098, along with records for points or other qualifying interest.

2. State and local taxes

State and local income taxes, sales taxes, real estate taxes, and certain personal property taxes may be deductible if you itemize. Limits and eligibility rules apply, so keep payment confirmations and tax statements.

3. Charitable contributions

Cash and property donations to qualifying organizations may be deductible when you itemize. Keep receipts or written acknowledgments from the organization. For valuable property, additional documentation or an appraisal may be required.

4. Medical and dental expenses

Some unreimbursed medical and dental expenses may qualify as itemized deductions after meeting applicable thresholds. Save receipts for medical care, prescriptions, insurance premiums, mileage, and other eligible costs.

5. Student loan interest

Eligible taxpayers may be able to deduct qualifying student loan interest without itemizing. Keep your annual loan interest statement and check the current income and loan requirements.

6. Educator expenses

Eligible teachers and other qualifying educators may be able to deduct certain unreimbursed classroom expenses. Keep receipts for supplies, books, and other qualifying purchases.

7. Childcare and dependent-care costs

Childcare expenses generally support a tax credit rather than a deduction, but they still belong on your tax preparation checklist. Keep the provider’s name, address, taxpayer identification number, dates of care, and amounts paid.

8. Education and adoption records

Tuition statements, required course materials, adoption fees, and related expenses may support credits or other tax benefits. Keep Forms 1098-T, adoption paperwork, invoices, and proof of payment.

Freelancer and self-employed tax deduction checklist

Freelancers, contractors, and gig workers commonly report business income and expenses on Schedule C when operating as a sole proprietor. The IRS self-employed individuals tax center includes information about filing, estimated taxes, Schedule C, and business obligations.

9. Home office expenses

A home office may qualify when a specific area is used regularly and exclusively for business, subject to IRS requirements. You may use an actual-expense method or, when eligible, the simplified method. Under current IRS guidance, the simplified method generally uses a prescribed rate per square foot with a maximum area limit.

Keep the square footage of your office and home, rent or mortgage records, utilities, insurance, repairs, and other supporting documents.

10. Office supplies

Paper, shipping materials, ink, notebooks, and other ordinary business supplies may be deductible when purchased for business use. Keep itemized receipts and avoid mixing personal purchases into the business category.

11. Computers, equipment, and software

Computers, cameras, tools, furniture, software, and other equipment may be deductible through current expensing, depreciation, or another applicable rule. Keep purchase dates, invoices, business-use percentages, and records showing when the item was placed in service.

12. Phone and internet

You may be able to deduct the business portion of phone and internet costs. A separate business line or clearly documented business-use percentage can make recordkeeping easier.

13. Business mileage and vehicle expenses

If you use a vehicle for business, you may generally choose between an applicable mileage method and actual expenses. Keep a mileage log showing the date, destination, business purpose, and miles driven. Do not include commuting or personal trips.

14. Travel

Business transportation, lodging, and other qualifying travel costs may be deductible when properly documented. Keep receipts, itineraries, and notes describing the business purpose of each trip.

15. Business meals

Qualifying business meals may be partially deductible, but special rules and exceptions apply. Record the date, location, amount, business purpose, and the people involved. Personal meals are not business deductions.

16. Advertising and marketing

Website costs, online ads, printed materials, promotional items, and other marketing expenses may qualify when they promote your business. Keep invoices and identify the business purpose.

17. Professional services

Fees paid for tax preparation, bookkeeping, legal services, accounting, consulting, and other professional help may be deductible when connected to your business.

18. Business insurance

Certain premiums for professional liability, general liability, commercial property, and other business coverage may qualify. Keep policy statements and payment records.

19. Retirement contributions

Eligible self-employed taxpayers may be able to deduct contributions to plans such as a SEP IRA, SIMPLE IRA, or solo 401(k). Contribution limits and deadlines vary, so include retirement planning in your annual tax review.

20. Self-employed health insurance

If you meet the requirements, health insurance premiums for yourself and certain family members may qualify for a self-employed health insurance deduction. Keep premium statements and verify eligibility based on your income and coverage.

Small-business deduction checklist

Good small business tax preparation starts with organized books. A business expense generally must be ordinary and necessary for your trade or business. “Ordinary” means common and accepted in your industry. “Necessary” means helpful and appropriate, not necessarily required.

21. Rent, utilities, and business space

Rent for an office, storefront, studio, warehouse, or equipment may be deductible when used for business. Business electricity, water, internet, and other utilities may also qualify. Keep leases, bills, and proof of payment.

22. Employee wages and benefits

Wages, payroll taxes, health benefits, retirement benefits, and other employee compensation may qualify as business expenses. Maintain payroll records, employment tax filings, and payment confirmations.

23. Contractor and subcontractor payments

Payments to freelancers, agencies, and independent contractors may be deductible when they provide services for your business. Keep contracts, invoices, payment records, and required information returns.

24. Inventory and cost of goods sold

Businesses that sell products generally need to track inventory and calculate cost of goods sold. Keep purchase invoices, shipping costs, inventory counts, and records of beginning and ending inventory.

25. Business interest, repairs, and depreciation

Interest on qualifying business loans and credit accounts may be deductible. Repairs that keep business property in working condition may also qualify, while improvements may need to be capitalized and depreciated. Keep loan statements, repair invoices, asset records, and depreciation schedules.

Recordkeeping tips that can protect your deductions

Use a system that makes it easy to match each expense to a receipt and business purpose.

• Keep a separate business bank account and credit card when possible.
• Photograph or scan receipts as soon as you receive them.
• Reconcile your books with bank and credit-card statements.
• Track mileage throughout the year instead of reconstructing it later.
• Save invoices, canceled checks, payment confirmations, and contracts.
• Keep records for as long as needed to support the income or deduction reported on your return.
• Review expenses monthly so missing information can be corrected while details are fresh.

How to work toward a maximum tax refund

A larger refund is not created by claiming questionable expenses. The best maximum tax refund tips are simple:

1. Report all income, including cash, app-based, freelance, and gig income.
2. Claim every legal deduction and credit you qualify for.
3. Keep business and personal expenses separate.
4. Check whether itemizing or taking the standard deduction is better.
5. Review your filing status and dependent information carefully.
6. Use accurate mileage and home-office records.
7. Plan ahead for estimated taxes if you are self-employed.
8. Have a professional review unusual expenses, large purchases, and business changes.
