Accounting Record Retention: Set a Schedule by Record Type

Set retention by the record, the event it supports, and every applicable obligation. For income-tax records, the IRS period-of-limitations guidance generally starts at three years, with longer periods for specified exceptions. Contracts, state law, regulators, legal holds, and property-basis records can require a different period.

TL;DR:

Keep employment-tax records for at least four years after the tax becomes due or is paid, whichever is later. Set ledger retention in the firm’s written policy after checking applicable obligations.

Preserve asset invoices, improvement records, and depreciation schedules through the asset’s sale and the applicable limitation period; carryover basis requires records for both exchanged properties.

Financial statements and corporate records should be kept permanently, while contracts should be retained through their term plus the applicable state limitation period.

Digital records can replace paper only when they remain legible, complete, searchable, and tested for accurate reproduction, with intact metadata and a verified backup.

A written retention matrix should assign each category an owner and disposal trigger, pause destruction during legal holds, and be reviewed at least annually.

Quick Reference: Common Records and Recommended Retention Periods

Different records carry different risks, so a single blanket rule leaves gaps. Tax returns and the records supporting them generally need three years, but basis and asset records need to survive much longer because they still prove numbers on a future return.

Tax returns and supporting schedules: keep 3 years from filing, or longer if you claimed a loss or credit tied to a later year.
Payroll and employment tax records: keep at least 4 years after the tax becomes due or is paid.
Bank statements and canceled checks: keep 3 years, longer if they support a disputed deduction.
Accounts receivable and payable detail: keep 3 years after the related return's filing date.
General ledger and journals: choose a documented retention period after reviewing tax, audit, legal, contractual, and operational requirements. A seven-year firm policy is an example, not a universal statutory rule.
Financial statements: keep permanently, since they document company history and support lender or buyer due diligence.
Asset purchase invoices and depreciation schedules: keep until disposition plus the applicable limitation period, because they establish basis.
Contracts: keep for the contract term plus the statute of limitations in your state.
Corporate records (minutes, stock ledgers): keep permanently.
Insurance policies and loan documents: keep for the life of the policy or loan plus several years after payoff.

State law, industry regulators, lenders, and insurers can all require longer holds than the tax rules alone demand, so treat this table as a floor, not a ceiling.

How to Decide How Long to Keep a Record

The period-of-limitations framework answers most retention questions once you know which exception applies.

Use this process on any record that isn't already in your matrix:

Identify the taxable event the record supports, such as a sale, a deduction, or a credit claim.
Pick the limitation period that applies to that event, including any extended period.
Check non-tax drivers, contracts, pending litigation, lender covenants, that might require a longer hold, then set retention to the longest applicable period.

Pro Tip: When in doubt between two plausible retention periods, default to the longer one. Storage is cheap; recreating a missing basis record years later usually is not.

Special Cases: Employment Tax, Asset Basis, Audits, and SEC Retention

A handful of exceptions cause most retention confusion, and each one overrides the standard three-year rule.

Employment tax records: keep for at least 4 years after the tax is due or paid, covering wages, withholding, and employer contributions.
Asset and basis records: keep until disposition plus the limitation period, since Publication 583 ties basis to the year the property is ultimately sold. Preserve the original purchase invoice, any improvement records, and the full depreciation schedule as one linked file.
Replacement property: when basis carries forward from an exchange, keep records for both the old and new property.
Audit and review workpapers: SEC Rule 2-06 requires seven-year retention for covered audits and reviews of issuers and registered investment companies. Do not apply that scope automatically to every bookkeeping engagement; check the rules governing the service.

These exceptions mean a single retention date rarely works across an entire file. Classify by record type first, then apply the matching rule.

Electronic Records and the Controls That Make Them Defensible

Scanned or system-generated files can replace paper originals, but the IRS expects the electronic system to produce legible, complete, and retrievable records, tested for accurate reproduction before you rely on it. Revenue Procedure 97-22 sets the underlying standard for indexing and retainability.

Before destroying any original, confirm the following with guidance on how to prepare your business for tax season:

The digital file is indexed and searchable by transaction, date, and vendor or customer.
Metadata from the original document, including creation and capture dates, exports intact.
A tested backup exists and has been restored at least once to confirm it works.
A documented procedure exists for both reproducing a record on request and destroying originals once retention has run.

Pro Tip: Run a sample reproduction test on your electronic storage system before relying on it for anything tied to asset basis or an open audit period.

How to Build a Defensible Retention Policy and Schedule

A written policy turns the rules above into something your team can actually follow without rechecking the law every time.

Define purpose and scope: which entities, departments, and record types the policy covers.
Build a classification scheme that groups records by type: tax, payroll, assets, contracts, corporate.
Assign a retention period, an owner, and a disposition trigger to each category in a simple matrix: category, retention period, owner, trigger, disposal method.
Add a legal hold process that suspends disposal whenever litigation, an audit, or a regulatory inquiry is pending.
Set a review cadence, at least annually, and keep a record-of-destruction log as evidence for auditors.

Documenting exceptions matters as much as the schedule itself. Our An Audit Readiness Checklist for Finance Teams walks through what auditors typically expect to see as proof that a policy was actually followed, not just written.

Common mistakes and quick fixes

For example, disposing of an equipment purchase file three years after acquisition can leave the basis unsupported when the equipment is sold later. Keep the invoice, improvements, and depreciation schedule together through disposition and the applicable limitation period.

Two fixes you can apply today: build a one-page retention matrix for your most common record types, and export your current fixed-asset file with full metadata attached before your next close.

FAQ

What are the IRS rules for document retention?

The IRS period-of-limitations rule generally requires keeping records 3 years from filing.

How do you account for retention in accounting?

Retention in accounting means tying each record's storage period to the tax, legal, or contractual event it supports, then holding it until the longest applicable limitation period expires. A retention matrix mapping document category to retention period, owner, and disposal trigger keeps this consistent across a firm.

What records need to be kept for 7 years?

The IRS specifies seven years for records supporting a claim for a worthless-security loss or bad-debt deduction. Separately, SEC Rule 2-06 imposes seven-year retention for covered issuer and registered-investment-company audit and review records. Other services and records need their own applicable-rule review.

What are the federal guidelines for document retention?

Federal regulation under 26 CFR §1.6001 requires keeping permanent books and records sufficient to establish income, deductions, and credits shown on a return. The IRS applies this through its period-of-limitations guidance, which sets specific retention windows depending on the situation.
