The self-employed tax checklist: receipts and records to gather

If you work for yourself, you report your business income and expenses on Schedule C and pay self-employment tax on Schedule SE. Getting ready is mostly about gathering the right records. Use this checklist to pull together everything you or your tax preparer will need.

First, the basics

You generally have to file a return if your net earnings from self-employment were $400 or more. Self-employment tax covers Social Security and Medicare, the same taxes an employer would withhold from a paycheck. Your business profit or loss goes on Schedule C, and self-employment tax is figured on Schedule SE, both filed with your Form 1040.

Income records

Gather everything that shows what you earned:

Forms 1099-NEC from clients who paid you
Forms 1099-K from payment apps and online marketplaces. For 2025 and 2026, these are issued when payments exceed $20,000 across more than 200 transactions.
Your own records of income that didn’t come with a form: invoices, deposit slips and payment-app histories

Expense receipts

Collect receipts and invoices for everything you’re deducting, grouped by type. Your documents should show the amount paid and that it was for your business. A bank statement alone isn’t enough.

Supplies, materials and inventory
Software, subscriptions and equipment
Advertising and marketing
Professional fees
Business insurance
Travel, and business meals (usually 50% deductible)
Phone and internet (the business share)

Vehicle and home office records

If you drive for business, you need a mileage log showing the date, destination, business purpose and miles of each trip. With the standard mileage rate, keep receipts for business parking and tolls, which are deductible separately. With actual expenses, keep receipts for gas, repairs, insurance and registration too.

For a home office, note the square footage of the space you use regularly and exclusively for business, and keep your rent or mortgage interest, utilities and insurance records if you use the regular method.

Estimated tax payments

Without an employer withholding tax, you generally have to make estimated tax payments if you expect to owe $1,000 or more when you file. The year is split into four payment periods, each with its own due date, and you can be charged a penalty for paying too little even if you end up due a refund. Gather records of every estimated payment you made, since you’ll report them on your return.

Make it a monthly habit

The easiest tax season is the one you prepare for all year. Once a month, spend ten minutes making sure every receipt is captured and filed, check that your income records match your deposits, and note any big purchases. By April, the checklist is mostly done.
