Tax Documents Checklist for W-2 and 1099 Filers in 2026

Updated October 1, 2026

Most tax forms are due to you by early February, and broker forms by mid-February. Gather your ID, last year's return, every W-2 or 1099, and records for anything that changed this year. Wait for all your forms before you file, since a missing one can mean a corrected return later.

When the forms show up

Here is when payers must send your forms. The law sets the date, and when that date lands on a weekend or holiday, it moves to the next business day. The pattern repeats each year, but the exact day changes.

Form W-2 from your employer: January 31 by law. January 31, 2027 is a Sunday, so for the forms covering 2026 the IRS says the due date is February 1, 2027.
Forms 1099-NEC, most 1099-MISC, 1099-INT, 1099-DIV, 1099-K, and 1098: also January 31 by law. For the forms covering 2025, January 31, 2026 was a Saturday, so the IRS date was February 2, 2026. The same rule gives February 1, 2027 for the forms covering 2026.
Form 1099-B from a broker: February 15 by law. For the forms covering 2025, February 15, 2026 was a Sunday and the next day was Washington's Birthday, so the IRS date was February 17, 2026.

Expect a similar rhythm every year, with exact dates set by the IRS. Some forms come late, so do not file at the first sign of a form until you have checked the list below.

Be careful with due dates, because a due date is not an arrival date. Employers and payers can be late, and a form can be corrected after it is first sent. A brokerage statement that arrives early may be replaced by a corrected version later, so it is worth waiting for the final version.

Everyone needs these

Photo ID for you and your spouse.
Social Security numbers, or ITINs, for everyone on the return, with correct spellings and birth dates.
Last year's federal and state returns.
Bank routing and account numbers for direct deposit or payment.
Any IRS letters you received this year.

Keep a folder, on paper or on your computer, that you add to all year. Toss in each pay stub summary, receipt, and letter as it arrives. By January most of the work is already done, and the only step left is to add the new tax forms as they come in.

W-2 workers

Every W-2, including from short jobs and jobs you left.
Unemployment statements (Form 1099-G), if you collected benefits.
Records of tips or other pay not on a W-2.
Your final pay stub of the year, to double-check the W-2.

Compare each W-2 to your last stub. If the numbers do not match, ask your employer for a corrected form.

If you had two or more jobs in the year, list them all, even a job that lasted a week. It is common to forget a short job and later find a W-2 from it. It is also worth listing any states where you lived or worked.

Also gather any letter about a health plan, any retirement account statement, and any paper about a job change or unemployment. These are easy to forget because they arrive at odd times, but each one can change what goes on the return.

1099 and self-employed workers

Every Form 1099-NEC, 1099-K, and 1099-MISC.
Your own income records. Forms can miss income or double count it.
Expense receipts and statements, sorted by category.
A mileage log. See the self-employed checklist for more.
Estimated tax payments you made and their dates. The IRS says to plan on them if you expect to owe $1,000 or more.

If you drive for work, our rideshare mileage guide shows what to log.

Freelancers often get forms from some clients and none from others. Every dollar earned still counts. Make a list of everyone who paid you, the total from each, and whether a form came.

Homeowners, parents and students

Homeowners: Form 1098 for mortgage interest, property tax bills or statements, and closing papers if you bought or sold. If you rent out a property, bring rent totals and expense records.

Parents: Social Security numbers for each child, childcare provider name, address, and taxpayer ID, and total paid for care. Bring any health coverage forms from a marketplace plan, if you had one.

Students: tuition statements from the school (Form 1098-T), records of books and required supplies, and student loan interest statements. If someone else may claim you as a dependent, tell us.

A tip for families: put every school, childcare, and health-related paper in one envelope through the year. Those small papers are the easiest to lose and the ones that come up most at filing time.

Investors

Form 1099-B for every sale, plus 1099-INT and 1099-DIV.
Purchase records for any sale where the cost basis is missing.
Crypto transaction history. See the crypto tax guide.
Retirement account statements and any forms for withdrawals or contributions.

Brokers can send corrected statements after the first one, so check before you file.

If you sold a home this year, bring the closing statement and a record of what you paid for the home and any big improvements. That information helps figure any gain, so it is worth digging out before you file.

How to send it and what happens next

Upload your documents securely after you start. There is no need to sort perfectly. Send what you have and tell us what is missing. A simple W-2 return starts at $99, a family return starts at $299, and a self-employed return starts at $450. Each final fee is set in a written quote, plus e-file and processing fees. Check pricing for more. We work remotely from anywhere. We prepare returns only.

If you are a first-time filer, or if your situation changed this year, add a short note listing what changed. A new job, a move, a marriage, a new baby, or a new business all belong on it. Your preparer will use it to decide which questions to ask.

Finally, check your mail and your online accounts for corrections in the weeks after the main forms arrive. Filing with the final version of each form saves you from redoing the return later.

FAQ

When should I file if a form is still missing?

Wait until it arrives if you can. Filing without a form risks a mismatch that can lead to a corrected return or a notice later. If the form is very late, contact the sender first.

What if I lost my W-2?

Ask your employer for another copy. You can usually also see wage details through your online IRS account, and your preparer can help you sort out what to do.

Do I need documents if I have no 1099?

Yes. Income is reportable even if a form never arrives. Keep your own records of what you earned.

How long should I keep my tax records?

Keep your return and supporting papers for several years, and keep records for property or investments for as long as you own them. Your preparer can tell you how long applies to your papers.
