Tax season goes a lot more smoothly when your records are organized before you start. This guide walks through the documents that individuals, self-employed taxpayers, rental property owners, and small businesses usually need to gather before meeting with a CPA.
The goal is not just to file a return. It is to give your preparer complete, accurate information so your income, deductions, credits, estimated payments, and state tax items can all be reviewed properly.
How to Use This Checklist
Treat this as a starting point. Not every item applies to every taxpayer, and some people need documents that are not listed here. Keep copies of all your tax forms, records, statements, and notices in one secure place before your appointment.
For the 2025 and 2026 tax years, pay extra attention to new and revised federal deductions, updated reporting rules, and the ways California differs from federal law. Some new deductions require additional records, and California does not always follow the federal rules.
What Changed for 2025–2026
A few recent federal changes affect the documents you may need to keep:
- New federal deductions. If you plan to claim deductions tied to qualified tips, qualified overtime, the senior deduction, or interest on certain personal vehicle loans, keep your wage statements, employer statements, Forms 1099, loan records, and other supporting documents.
- Form 1099-K threshold. The reporting threshold for third-party payment platforms generally returned to more than $20,000 and more than 200 transactions. You may still receive a 1099-K below that level, and taxable income must be reported even if no form is issued.
- Payment card transactions. Card processors generally issue a 1099-K without the same threshold that applies to payment apps and marketplaces.
- Energy and vehicle credits. These have changed in recent years. If you think a credit may apply, keep purchase agreements, placed-in-service dates, invoices, manufacturer certifications, and vehicle identification details.
- California differences. Keep California-specific forms, payment confirmations, FTB notices, LLC vouchers, payroll records, and estimated tax confirmations.

Frequently Asked Questions
What documents do I need for tax preparation?
Most taxpayers need identification, income forms, deduction and credit records, estimated payment confirmations, and prior-year returns. Business owners also need organized income, expense, payroll, asset, and bookkeeping records.
What if I am missing a form?
Contact the issuer as soon as you can. If you cannot get the form before filing, other records may help your preparer decide whether the return can still be prepared accurately.
Do I need receipts for every deduction?
Requirements vary by deduction. Keep enough records to support the amount, date, business purpose, and tax treatment of anything you report.
How long should I keep tax records?
Many taxpayers keep records for at least three years, but some situations call for longer. Keep employment tax records for at least four years, keep records longer if you omitted substantial income, and keep them indefinitely if no return was filed or if fraud is involved.
