There is no single retention period for every small-business financial record. Three years is a common federal tax benchmark, but treating it as a universal disposal rule can cause trouble. The right period depends on what a record proves, the return and transaction involved, when the tax was paid, whether employees or business property are involved, and whether another legal or business requirement applies.
The following framework can help Kitsap County business owners build a retention schedule. It is general information, not individualized tax or legal advice.
Start with the tax return the record supports
The IRS says businesses generally should retain records supporting income, deductions, and credits until the period of limitations for the related return expires. That period is the time during which a taxpayer may amend a return to claim a credit or refund or the IRS may assess additional tax.
Under the IRS framework, the relevant periods include:
- Three years: The general period when none of the longer-period circumstances applies.
- Three years after filing or two years after paying the tax, whichever is later: When retaining records for a credit or refund claim made after filing the return.
- Seven years: For records supporting a claim involving worthless securities or a bad-debt deduction.
- Six years: If omitted income exceeds 25% of the gross income reported on the return.
- Indefinitely: If no return was filed or a fraudulent return was filed.
These are limitation periods, not a recommendation to discard every document as soon as a stated number of years passes. The IRS also advises keeping copies of filed returns because they can help with future filings and amended-return calculations. Review the agency’s current record-retention guidance before applying these periods.
Follow the transaction, not just the calendar
A useful retention decision starts with one question: What does this document establish? A receipt may support an expense. An invoice and payment record may establish revenue. A loan agreement may explain why money entered the bank account without being a sale.
Keep the full evidence chain when one document does not tell the whole story. For example, a bank statement may show that a deposit occurred but not whether it was sales revenue, owner funding, borrowed money, or a transfer between accounts. Our article about why a bank deposit needs a supporting record explains how to preserve that context.
Keep property records through ownership and disposal
Asset documentation often needs to stay in the file much longer than an ordinary receipt. The IRS says records related to property generally should be retained until the limitation period expires for the year in which the property is disposed of.
Those records may be needed to establish purchase cost, improvements, depreciation, amortization, depletion, and the gain or loss on a later sale. If property was received through a nontaxable exchange, records for both the old and replacement property may remain relevant until after the replacement property is disposed of.
In practice, avoid starting the retention clock for a long-lived asset on its purchase date alone. Start with the asset’s complete ownership history and the return reporting its eventual disposition.
Put employment tax files in a separate category
Employers should not place payroll and employment tax records into a general three-year disposal batch. The IRS requires employment tax records to be kept for at least four years after the tax becomes due or is paid, whichever is later.
Because “whichever is later” matters, record both the filing or due date and the payment date when assigning a destruction date. IRS Publication 583 provides additional federal recordkeeping guidance for businesses and describes records commonly generated by purchases, sales, payroll, and other transactions. The IRS currently lists Publication 583, Starting a Business and Keeping Records, as revised in December 2024.
Check non-tax reasons before deleting anything
Expiration of a federal tax period is only one checkpoint. The IRS specifically cautions businesses to determine whether records are still required for other purposes; creditors or insurers, for example, may require longer retention.
Also consider active contracts, ownership disputes, litigation holds, warranties, insurance claims, financing terms, and applicable federal, Washington, or local requirements. Unusual transactions, unresolved returns, asset exchanges, bad debts, missing filings, and pending disputes warrant professional advice before records are destroyed.
Build a record-by-record retention schedule
For each record category, document:
- What the record proves.
- Which return, asset, employee, contract, or transaction it supports.
- The filing, payment, disposal, or contract-end date that starts the retention period.
- The applicable tax period.
- Any longer non-tax requirement.
- A review date rather than an automatic deletion date when circumstances are uncertain.
Store supporting documents with enough context that another person can understand them. If records are moving between systems or professionals, a structured records handoff folder can reduce the chance that source documents, tax returns, or asset histories are left behind.
Next step: Compare your current retention schedule with the IRS guidance and Publication 583, then ask an appropriately qualified tax or legal professional to review categories involving unusual filing facts, employees, property, disputes, or other legal obligations. Reviewing public guidance is separate from professional-license verification; verify any claimed license or credential with its issuing authority before engaging a professional.
