What Receipts Should I Keep for Taxes? IRS Rules for Small Business
The IRS doesn't care that you have a bank statement. Bank statements prove you spent money — they don't prove what you spent it on, which is what a receipt does. If you're deducting an expense, the IRS can ask you to prove it, and a debit card charge alone often isn't enough.
This guide is the practical version of IRS Publication 583 ("Starting a Business and Keeping Records") and Publication 463 ("Travel, Gift, and Car Expenses"), written for small business owners in plain English.
The general rule
Keep receipts and supporting documents for any expense you deduct. The IRS's own guidance is that records must be sufficient to establish:
- The amount of the expense
- The date it was incurred
- The place (for travel/meals)
- The business purpose
A credit card statement gives you amount and date. It usually doesn't give you place or purpose. That's the gap a receipt fills.
What you must keep
| Category | Documents to keep | Notes |
|---|---|---|
| Sales and income | Invoices, sales slips, deposit slips, 1099s, cash register tapes | Match your gross receipts total |
| Purchases | Canceled checks, invoices, credit card receipts, cash register tapes | For cost of goods sold |
| Expenses | Receipts, canceled checks, credit card slips, invoices | The main "receipt" category |
| Travel & entertainment | Receipt + purpose written on it | Any T&E charge $75+ must have a receipt (Pub 463) |
| Vehicle expenses | Mileage log, gas receipts, maintenance receipts | Either actual expense or standard mileage — pick one method per year |
| Meals | Receipt showing amount, date, place, attendees, business purpose | 50% deductible in most cases |
| Payroll | W-2s, W-4s, W-9s, 941s, 940s, state filings | Keep 4 years minimum |
| Assets (fixed assets) | Purchase invoice, depreciation records | Keep for life of asset + 3 years |
| Home office | Bills for utilities, rent/mortgage, home insurance, repairs | Keep for as long as you claim the deduction + 3 years |
Which small receipts you don't strictly need
Under Pub 463, individual travel and entertainment charges under $75 don't require a physical receipt — but you still need a written record (date, amount, place, purpose). Lodging always requires a receipt regardless of amount.
Practical translation: keep everything anyway. Digital receipt capture costs you nothing, and the $75 exemption doesn't apply to non-T&E expenses.
How long to keep them
This is where most small businesses get it wrong. The IRS's record-retention rules depend on what the record is for.
| Situation | Keep records for |
|---|---|
| Standard: filed a correct return | 3 years from filing date |
| Claim for credit/refund after filing | Later of 3 years from filing or 2 years from tax paid |
| Understated income by 25%+ | 6 years |
| Claim a loss from worthless securities or bad debt | 7 years |
| Didn't file a return | Indefinitely |
| Filed a fraudulent return | Indefinitely |
| Employment tax records | At least 4 years after tax is due or paid, whichever is later |
| Fixed assets | Life of the asset + 3 years |
The safe default for small businesses: keep everything for 7 years. Storage is cheap; audit prep isn't.
Digital receipts count
The IRS accepts digital records under Revenue Procedure 97-22. Requirements:
- Records must be legible and accurate
- The system must produce readable hard copies on request
- Records must be organized and retrievable by year and category
- Original paper receipts can be destroyed once digitized (except for certain legal documents)
Translation: photographing a receipt in your accounting app is legally equivalent to keeping the paper.
How to organize receipts (that actually works)
The system doesn't have to be sophisticated. It has to be consistent and retrievable.
Minimum viable system:
- Capture receipts within 48 hours of the expense
- Attach each receipt to the corresponding transaction in your accounting software
- Include a one-line business purpose in the description
- Back up receipts monthly to a second location (cloud storage)
In Ledger Flow, this is a two-tap workflow: photograph the receipt, the AI extracts the merchant, amount, and date, matches it to a bank transaction, and stores it against the transaction record with the audit trail intact.
Special situations
Meals with clients
Post-2017 tax reform, entertainment is generally non-deductible; meals with a business purpose remain 50% deductible. Your receipt must show:
- Amount, date, and place
- Attendees (names and business relationship)
- Business purpose (why did this meal happen?)
A one-line note on the receipt is enough. "Q4 planning with Sarah (client, ABC Corp)" beats a plain receipt every time.
Vehicle expenses
If you use the standard mileage rate (65.5¢/mile for 2026 assumed rates — verify current), keep a contemporaneous mileage log. Reconstructed logs are the #1 thing the IRS disallows. Log the trip the day it happens.
If you deduct actual expenses, keep gas, insurance, maintenance, and depreciation records.
Home office
Keep utility bills, rent or mortgage statements, insurance premiums, and any home-improvement or repair receipts related to the office space. The simplified method ($5/sq ft up to 300 sq ft) doesn't require these — but locks you out of depreciation.
Red flags the IRS looks for
- Round-number expenses ($500, $1,000) without receipts
- Meal expenses > 50% of a category
- Large cash expenses without contemporaneous notes
- Vehicle logs written in the same handwriting/ink over months
None of these are prohibited. They just increase audit risk.

Frequently Asked Questions
Do I need a receipt for every business expense?
Under IRS Publication 463, travel and entertainment expenses under $75 don't require a physical receipt if you keep a written record with date, amount, place, and purpose — but lodging always requires one. For all other expenses, keeping a receipt is the safe standard.
Can I use digital receipts for the IRS?
Yes. Under Revenue Procedure 97-22, digital receipts are legally equivalent to paper if they're legible, accurate, retrievable, and organized. Most accounting platforms, including Ledger Flow, satisfy these requirements.
How long do I need to keep tax records?
The IRS baseline is three years from the filing date, but the safe default for small businesses is seven years. Fixed-asset records should be kept for the life of the asset plus three years, and employment records for at least four years.
Is a bank or credit card statement enough proof for the IRS?
Usually not. Statements prove the amount and date but not the business purpose or place — which the IRS requires for most deductions. A receipt plus a one-line business purpose is the durable standard.
What happens if I lose a receipt?
You can still deduct the expense if you can reconstruct sufficient evidence: bank/credit card statement plus a contemporaneous note explaining the purchase and business purpose. The IRS accepts reasonable reconstruction, but repeated missing receipts increase audit risk.
Do I need receipts for meals with clients?
Yes, and the receipt must include the amount, date, place, attendees, and business purpose. Client meals are generally 50% deductible in 2026, and the documentation requirement is stricter than for other expenses.
