Client Record Retention Checklist for Small Businesses

What client records should a small business keep, and for how long?

A record retention checklist organizes your business documents by category, applies the correct retention period to each category, and gives you a repeatable reference for the next time you review what to keep and what to dispose of. The checklist below covers the five main categories most small businesses encounter, drawn from IRS rules, federal employment requirements, and CPA practice guidance.

For the full explanation of why each period is what it is, see the main article on how long to keep client records.

Retention checklist by category

Permanent retention (never discard)

These records should never be disposed of regardless of age:

• Actual filed tax returns including canceled checks from tax payments (Source: MBK CPA)
• Business formation documents (articles of incorporation, operating agreements, EIN letters)
• Year-end financial statements
• Property acquisition records for property you still own

Action: Move these into a clearly labeled “permanent” folder or archive and exclude them from any scheduled purge.

Tax-supporting records (3–7 years)

These documents back up the numbers on your tax returns. The period depends on the scenario:

Action: For each tax year, keep all supporting documents (invoices, receipts, bank statements, worksheets) until the longest applicable period has expired. When in doubt, use the seven-year period as a safe default for tax records.

Property records (until disposition + limitations period)

Property records include purchase documents, depreciation schedules, improvement records, and records of any sale or exchange.

• Keep records relating to property until the period of limitations expires for the year in which you dispose of the property (Source: IRS).
• Canceled leases and notes receivable can be kept for 10 years after cancellation (Source: MBK CPA).

Action: For each property asset, note the acquisition date, the expected or actual disposition date, and calculate the retention expiry from the disposition year.

Employment tax records (at least 4 years)

Employment tax records must be kept for at least 4 years after the date the tax becomes due or is paid, whichever is later (Source: IRS). This includes:

• Payroll records and W-2s
• W-4 forms and withholding records
• Tax deposit records
• Quarterly and annual employment tax filings

Action: For employers, maintain a separate employment-tax archive organized by tax year, and verify that the four-year minimum is counted from the later of the due date or actual payment date.

Exposure and industry-specific records (up to 30 years)

Documents relating to workers’ exposure to harmful agents must be kept for 30 years after employment ends (Source: CO- by US Chamber of Commerce). This applies to businesses in industries where occupational exposure monitoring is required.

Action: If your business involves chemicals, industrial materials, or other exposure risks, verify the OSHA requirements for your specific situation and maintain the applicable records for the full period.

A quick-reference summary

One step you can take today

Open your most recent filing system (physical or digital) and label each folder with its category from the table above. You do not need to sort individual documents yet — just tagging the top-level folders tells you which retention rule governs the contents and which folders to review first at the next annual purge.
