What Documents Do You Need to File Taxes in 2027?

The single most useful thing you can do before a tax appointment is pull your paperwork together in one place. It sounds ordinary, but the difference between a smooth filing and a back-and-forth hunt for missing documents usually comes down to how ready you walk in. This guide walks through the categories most filers need to think through before they file.

Start with identification

Every person on a return has to be identified. Bring a government-issued photo ID for yourself (and your spouse, if you're filing jointly), plus Social Security cards or Individual Taxpayer Identification Numbers (ITINs) for you, your spouse, and any dependents. These details confirm who you are and line up with what the IRS has on file.

Income documents (W-2s and 1099s)

Income documents are the backbone of your return. If you were an employee, gather every Form W-2 you received for the tax year — including ones from jobs you left during the year. If you worked as a contractor, freelancer, or gig worker, round up your 1099-NEC and 1099-MISC forms. Other common 1099s cover interest and dividends (1099-INT, 1099-DIV) and retirement distributions (1099-R).

One thing that surprises people: income you earned without receiving a 1099 still counts. If a client paid you under the 1099 reporting threshold, you still report that income — so keep your own records and nothing slips through.

Self-employment and business income

If you're self-employed, bring a summary of business income and expenses, mileage logs, and a record of estimated tax payments you made during the year. The cleaner those records are, the more accurately your return can be prepared. See our self-employed tax filing guide for a closer look.

Dependent information

When you claim dependents, bring each one's full name, Social Security number or ITIN, date of birth, and the number of months they lived with you during the year. Dependent eligibility follows IRS rules around residency, support, and relationship — bring the details and we apply the rules that fit your household.

Deduction and credit documents

Depending on your situation, you may have documents that support deductions or credits: education expenses (Form 1098-T), student loan interest, mortgage interest (Form 1098), property tax records, childcare costs, and retirement contributions. Whether itemizing or taking the standard deduction makes more sense depends on your full picture — we help you weigh it.

Prior-year return and bank information

A copy of last year's return helps us carry forward carryovers, confirm prior details, and spot what changed. And if you're expecting a refund and want direct deposit, bring your bank's routing and account numbers — direct deposit is usually faster than a paper check.

A note on the tax year

The documents you need can shift from year to year as tax rules and forms are updated. The checklist above covers the common categories; the exact documents for you depend on your situation and the rules for the tax year being filed. Our full tax filing checklist covers these categories in more detail.
