Build a Tax-Record Retention Calendar With Your CPA

October 4, 2026 · Small Business guide · 2 min read

Record retention is not a single number that applies to every business document. The relevant period can depend on the tax issue, return, asset, legal obligation, and state rules. Build a schedule with your tax professional that explains the rule and the business reason for keeping each record.

Inventory records by purpose

Separate filed returns, supporting receipts, payroll, bank statements, contracts, asset basis, employment records, and sales-tax documentation. Identify the official source or adviser that determines the retention period for each category.

Tie each period to a trigger

Some periods start from filing, payment, sale, or another event. Record the trigger date and cite the rule or written professional advice. Flag exceptions such as amended returns, carryforwards, audits, property basis, or unresolved disputes.

Assign custody and access

Name the system of record, responsible role, backup process, access controls, and format. Preserve readability and retrieval ability; a folder full of scans is not useful if nobody can identify the transaction or reporting period.

Review the schedule annually

Ask the CPA to recheck categories when the business hires staff, buys or sells property, changes entity structure, operates in a new state, or faces a notice. Document destruction approvals and legal holds.

The IRS page explains federal tax recordkeeping and includes context-specific exceptions. State, employment, corporate, and litigation rules may require different treatment; confirm the schedule with qualified advisers.

For a starting point, browse the directory search, then verify details with the organization responsible for the record. See IRS recordkeeping guidance.
