Keep most business receipts and invoices for at least three years from the date you file the related tax return, since that is the IRS standard period for assessing additional tax or for you to claim a refund. To be safe, many accountants recommend holding records for seven years, and certain documents (like property and employment records) should be kept even longer. When in doubt, keep it.
The short answer, by record type
The right retention period depends on what the document supports. Here is the schedule most U.S. small businesses can follow.
| Record type | Keep for | Why |
|---|---|---|
| General receipts & invoices | 3 years | Standard IRS limitations period |
| Records with income underreporting | 6 years | IRS extends the window if >25% of income is omitted |
| Employment tax records | 4 years | Required after tax is due or paid |
| Property & asset records | Life of asset + 7 years | Needed to calculate depreciation and gains |
| No return filed / fraudulent return | Indefinitely | No limitations period applies |
| Records for loans or investors | Life of loan + 3 years | Lenders and partners may request them |
Why three years is the baseline
The IRS calls this the "period of limitations." For most returns, you have three years to amend a return and claim a refund, and the IRS generally has three years to assess additional tax. After that window closes, your supporting receipts and invoices are far less likely to be requested.
That three-year rule assumes everything on your return is reasonably accurate. The moment a return gets more complicated, the clock runs longer.
When you need to keep records longer
- Six years if you fail to report income that is more than 25% of the gross income shown on your return.
- Seven years if you file a claim for a loss from worthless securities or a bad debt deduction.
- Four years for employment tax records, kept after the date the tax becomes due or is paid.
- Indefinitely if you do not file a return or file a fraudulent one. There is no limitations period in those cases.
How real is the audit risk?
Audit odds are low but not zero, and they are meaningfully higher for business owners and the self-employed than for typical wage earners. In fiscal year 2024 the IRS closed more than 505,000 audits and recommended over $29 billion in additional tax assessments.
Most of those exams are not the dramatic in-person visits people imagine. In 2024, 77.9% of audits were conducted by mail, where the IRS simply asks you to substantiate a deduction or line item. If you can produce the receipt or invoice quickly, a correspondence audit is often resolved with minimal friction. If you cannot, the IRS can disallow the deduction outright.
This is the core reason retention matters: your records are the evidence that protects the numbers you reported.
Receipts vs. invoices: keep both
People often treat these as interchangeable, but they prove different things.
- Invoices show what you billed or were billed. A sales invoice documents revenue; a vendor invoice documents an expense or deduction. Knowing what to include on an invoice makes each one a cleaner audit trail.
- Receipts prove payment actually changed hands. A receipt confirms a customer paid you, and a cash receipt is especially important for cash transactions that leave no bank trail.
For deductions, the IRS generally wants to see both the invoice (what the expense was for) and the receipt or bank record (that you paid it). Pairing them removes ambiguity.
Digital records are fully acceptable
You do not have to keep a shoebox of fading paper. The IRS accepts electronic records as long as they are legible, accurate, and accessible if requested. Scanned PDFs of receipts and invoices are valid, and digital storage solves the most common record-keeping failure: lost or damaged paper.
A few practices keep digital records audit-ready:
- Save documents in a consistent format like PDF, and back them up in two places.
- Name files clearly by date, vendor, and amount.
- Keep the original generated invoice, not just a screenshot, so the full detail is preserved.
Why good records pay off beyond taxes
Retention is not only about surviving an audit. Clean records make you faster at collecting what you are owed, and slow collections are a widespread problem. According to Intuit QuickBooks, 56% of U.S. small businesses report being owed money from unpaid invoices, averaging about $17,500 per business.
When you can instantly pull the original invoice and proof of delivery, chasing a late payment becomes a one-email task instead of a forensic project. Organized records also speed up loan applications, due diligence, and year-end bookkeeping.
A simple retention system that works
You do not need accounting software to stay compliant. A workable system has three parts:
- Generate clean documents. Use a consistent invoice and receipt format so every record is complete from the start.
- Store by tax year. Create one folder per year. Drop invoices and receipts in as you go, not in a March scramble.
- Purge on schedule. Once a tax year clears the seven-year mark, you can usually delete the routine records, keeping permanent items like asset and property documents.
The hardest year to reconstruct is always the current one, so capturing documents at the moment of the transaction is the single highest-return habit.
Frequently asked questions
How long should I keep business receipts for taxes?
Keep most business receipts for at least three years from the date you file the related tax return, matching the standard IRS limitations period. Hold them seven years if a receipt supports a bad-debt or worthless-securities claim, or if there is any chance of underreported income, which extends the IRS window to six years.
Can I throw away paper receipts if I scan them?
Yes. The IRS accepts legible, accurate electronic records, so a clear scan or PDF is valid proof. Once a digital copy is securely stored and backed up, you can safely discard the paper original. Make sure scanned receipts remain readable and accessible if the IRS requests them.
How long should I keep invoices for my own business?
Keep both the invoices you send and the invoices you receive for at least three years, and up to seven to be safe. Sales invoices document your income, while vendor invoices support your deductions. Both are primary evidence if a return is examined, and they also help you collect overdue payments.
What happens if I cannot find a receipt during an audit?
The IRS can disallow the deduction tied to a missing receipt, which may increase your tax, plus interest and possible penalties. In some cases auditors accept bank or credit-card statements as secondary proof, but a clear original receipt is far stronger. This is exactly why consistent retention matters.
The bottom line
Three years is the floor, seven years is the safe default, and a handful of records should be kept far longer or indefinitely. Audits are uncommon but consequential, and most are resolved by simply producing the right document. Build a habit of generating clean invoices and receipts and filing them by tax year, and record retention stops being a worry and becomes a quiet competitive advantage.
