A clear reference list of the forms, records, and numbers you should have on hand before starting your tax return — so nothing slows you down.
Why Preparation Matters Before You Start
Opening a tax return without your documents in front of you is one of the most common beginner mistakes. You may enter a wrong number, skip an income source you forgot about, or have to abandon a half-finished return and start over. None of that is enjoyable - and some errors can trigger IRS notices or delay your refund by weeks.
This checklist is designed to be your pre-flight check. Work through it before you open any tax software or fill in a single box. If you're filing for the very first time, you may also want to review our guide to common tax forms so you know what each document is reporting before you begin.
Not every item on this list will apply to you. Skim the categories, identify what's relevant to your situation, and gather only what you need. The goal is to sit down, open your return, and move through it without interruption.

What to Do If a Document Is Missing
Employers are required by law to send W-2 forms to employees by January 31 each year. Financial institutions typically send 1099 forms by mid-February. If a deadline has passed and you haven't received a form you expected, take these steps in order:
Check your email and online accounts. Many employers and brokerages deliver documents electronically through employee portals or account dashboards.
Contact the issuer directly. Your employer's payroll department or your bank's customer service line can reissue or resend a missing form.
Use IRS Form 4852 as a last resort. If a W-2 is truly unattainable, Form 4852 lets you substitute your own wage estimate based on your final pay stub. The IRS allows this, but it should be a last resort rather than a first move.
Don't Estimate Income You Have a Form For
If you received a W-2 or 1099 for income, the IRS already has a copy of that same document from the issuer. Entering a different number - even accidentally - can trigger an IRS notice or delay your refund. Always copy figures directly from your official forms rather than from memory or pay stubs.
