Tax return document checklist
Before your tax appointment, gather every income form (W-2s, 1099s and K-1s), your business profit and loss, records for deductions like mileage and your home office, proof of estimated payments, and last year's return. This checklist covers it all, so your return isn't held up waiting on one missing form.

How do I use this checklist?
Tick items as you find them. Your ticks stay in this browser only, and nothing is sent anywhere. If something doesn't apply to you, tick it anyway so the list shows what's left. Send everything to your accountant at once, rather than in pieces, so they can start on a complete file.
What if a form is missing?
Most 1099s and W-2s arrive by January 31, and K-1s can come as late as September 15. If one is late, ask the payer first. If it still doesn't come, your accountant can file an extension and work from your own records. Need help? Our personal tax return service starts from this list.

General information, not tax advice for your situation.
When should I start gathering documents?
In January, as forms arrive. Most W-2s and 1099s are due to you by January 31, and brokerage forms by mid-February.
Do I need receipts for every expense?
Keep records that show what you bought, when, and why it was for business. Bank and card statements help, but receipts back up the larger and less obvious items.
What if I don't have a profit and loss statement?
Your accountant can build one from your bank and card statements, though that takes longer. Monthly bookkeeping keeps it ready.
