What records do I need to keep for my business?

The IRS expects you to maintain records that support everything on your tax return. But record-keeping goes beyond surviving an audit. Clean records make bookkeeping easier, help you understand your business, and save time when tax season arrives.

Financial records form the foundation. Keep all bank statements, credit card statements, and canceled checks. Your income documentation should include invoices you’ve sent, payment receipts, and any 1099 forms you receive. For expenses, save receipts for everything you plan to deduct. A credit card statement shows you spent $312 at Home Depot, but it doesn’t prove what you bought or that it was for business purposes. The receipt does.

Tax returns and all supporting documents need to stay on file. This includes prior year returns, W-2s and 1099s, depreciation schedules, and any correspondence with the IRS or state agencies. If you claimed a deduction, you should be able to trace it back to the documentation.

Employment and payroll records require special attention. Keep all W-4 forms, I-9s, timesheets, payroll reports, and records of wages paid. You’ll also need documentation for any benefits provided and employer tax deposits made. The IRS requires you to keep employment tax records for at least four years after the tax becomes due or is paid, whichever is later.

Legal and formation documents should be kept permanently. This includes your articles of incorporation or organization, operating agreements, business licenses, permits, contracts, and insurance policies. These don’t expire for record-keeping purposes.

Asset records matter for depreciation and eventual sale. When you buy equipment, vehicles, or property, keep the purchase documentation showing what you paid, when you bought it, and how it’s being used. You’ll need this information for years to calculate depreciation correctly and to determine gain or loss when you sell.

Retention periods vary by record type. The IRS generally has three years to audit a return, but that extends to six years if you underreport income by more than 25% and indefinitely if fraud is involved. Most accountants recommend keeping tax returns and supporting documents for seven years. Payroll records should be kept for at least four years. Legal documents and asset records stay forever or until well after the asset is disposed of.

A Nampa business tax preparation service can help you understand which records matter most for your specific situation. The goal is documentation that supports your tax positions and gives you the information needed to run your business. When records are organized and complete, everything else gets easier.
