If the IRS ever questions a deduction, the burden is generally on you to show the expense was real and business-related. A credit card statement alone often is not enough, because it shows that you paid but not what you bought or why.
Good recordkeeping takes a few minutes a week and protects every deduction you claim. Here is what to keep and for how long.
What to keep
For most freelancers and gig workers, the core records are:
- Invoices, payment platform reports, and bank deposits that show income
- Receipts showing what was bought, when, from whom, and how much
- A mileage log with dates, destinations, business purpose, and miles
- Notes on who attended business meals and what was discussed
- Records for equipment purchases, including the date first used for business
- Copies of filed returns, 1099s, and estimated payment confirmations
Digital copies count
The IRS generally accepts electronic records, including scanned or photographed receipts, as long as they are legible and complete. Snapping a photo of a receipt the moment you get it and saving it to a dated folder or accounting app is one of the easiest habits you can build. Faded thermal-paper receipts are a common way records quietly disappear.
How long to keep records
The general rule is to keep records for at least three years from the date you filed the return, since that is the usual window for the IRS to assess additional tax. Some situations extend it:
- Six years if you underreported income by more than 25% of what you reported
- Seven years if you claimed a loss from worthless securities or bad debt
- For as long as you own an asset, plus three years after the return reporting its sale, for equipment and property records
- Indefinitely if a return was never filed or was fraudulent
Do not forget your state
Some states have longer review periods than the IRS. Check your state tax agency's guidance, and when in doubt, keep records for the longer period. Storage is cheap compared to losing a deduction.
A simple yearly routine
After you file, save a copy of the return and a single archive folder with every supporting document for that year. Note the date it becomes safe to discard. Combined with a separate business bank account, that routine means any question about your return can usually be answered in minutes rather than days.
