Seven years is the safe default for most business financial records. The IRS generally has three years from the filing date to audit your return, but that extends to six years if they believe you underreported income by more than 25%. Keeping records for seven years covers both scenarios with a buffer.

Tax returns themselves should stay in your files permanently. You don’t need all the supporting documents forever, but the actual returns serve as proof of filing and provide reference points if questions arise years later. The same goes for annual financial statements, depreciation schedules, and any documents related to asset purchases since you may need to prove your cost basis when you sell.

Bank and credit card statements, receipts, invoices, and general ledger records fall into that seven-year category. These support the deductions and income you reported on your tax returns. If you claimed a deduction and get audited, you need the documentation to prove it was legitimate. Without records, the IRS can disallow deductions entirely.

Payroll records have their own requirements. The IRS requires you to keep payroll tax records for at least four years after the tax is due or paid, whichever is later. Massachusetts requires employers to keep payroll records for at least three years. But other employment laws extend this further. The EEOC recommends keeping employment records for at least one year after an employee leaves, and some wage and hour regulations suggest three years. Keeping payroll records for seven years covers all these overlapping requirements.

Contracts, leases, and legal documents should stay in your files for the duration of the agreement plus at least seven years after they end. Loan documents should be kept until the debt is fully paid off and then seven more years. If you ever face a dispute, having the original documents matters.

A small business bookkeeping service can help you establish a system for organizing and storing records so you’re not scrambling when you need to find something. The goal is having everything accessible but not drowning in paper you’ll never need again.

Digital storage makes retention easier. Scan paper receipts and invoices since thermal paper fades over time anyway. Cloud backups protect against fire, flood, or hard drive failure. Just make sure your digital files are organized with consistent naming and folder structures so you can actually find what you need. Ongoing bookkeeping naturally creates this documentation trail month by month rather than leaving you to reconstruct everything later.

The penalty for keeping records too long is just clutter. The penalty for discarding them too early can be denied deductions, unprovable claims, and penalties in an audit. When in doubt, keep it seven years.
