Preparing your tax return, whether independently or with a professional, should start with organization. Collecting the proper documents before starting your taxes helps ensure accuracy, reduces stress, and may prevent missed deductions or credits.
Here’s a tax preparation checklist to help you get started.1
Prior-year tax return
Having your tax return from last year on hand will remind you of certain elections made, income reported, deductions taken, depreciation schedules, carryovers, etc. If you e-filed and didn’t print a copy, retrieve your identity protection PIN (IP PIN) to access the return.
Income and earnings records
- W-2 forms from all employers
- Equity compensation records, including 83(b) elections, cost basis, and holding periods
- 1099-INT, 1099-DIV, 1099-B, or consolidated brokerage statements showing investment interest, dividends, and capital gains

Following this checklist can help ensure you gather the essential tax filing documents. However, individual circumstances may require additional records. Tax laws and reporting requirements continue to evolve, making professional guidance increasingly valuable.
