How long should businesses keep invoices?
Short answerA business should keep invoices and other records that support its tax return until the period of limitations for that return runs out, which the IRS says is generally three years [1]. Records tied to employees' taxes should be kept at least four years [2]. Longer retention can help with disputes.
The explanation
The IRS ties retention to the purpose of the record rather than to a single number for everything [1]. Sales invoices, expense receipts, mileage logs and bank statements all support the return, so they follow the same clock [1].
Employment records have a different clock. The IRS says employment tax records should be kept for at least four years [2]. If you have crew on payroll, keep time records and payroll reports with those, not in the same short-term folder as receipts.
Beyond taxes, think about risk. Warranty work, insurance claims and customer disputes can stretch past three years. A simple rule is to keep invoices and job records for a longer period you set in writing, and to keep payroll and tax filings as long as your accountant advises. Check your state.
Steps
- List the record types you hold: sales, expenses, payroll, contracts.
- Set a retention period for each in a one-page note.
- Store digital copies with dates and customer names.
- Review the retention note again each January.
What to watch for
- One retention rule applied to every record type.
- Throwing out payroll files with the receipts.
