How Long Do I Need to Keep Business Tax Records?

The IRS, other taxing authorities, creditors, and investors all might demand to see a business's tax records. Without documentation, a company might have difficulty defending its deductions during a tax audit, applying for a loan, or obtaining new investors.

Knowing how long to keep tax returns and other records can help businesses respond to information requests. Additionally, owners can use this information to better understand their businesses.

Companies can safely discard most documents seven years after filing the related tax return—or seven years after the due date, if later. However, a few records require indefinite retention.

What are business tax records?

Business tax records include anything that directly or indirectly supports amounts claimed on the business's tax returns. Examples include:

• Invoices
• Cash register tapes
• Canceled checks
• Bank statements
• Receipts
• Credit card statements
• Real estate closing statements
• Bills of sale
• Tax forms
• Tax returns

Transactions usually generate these documents automatically. Businesses (or their accountants) then record the accounting effects of transactions and file the supporting records based on the type of transaction and when it occurred.

Digital file management systems offer many advantages, though companies must keep paper originals of some documents. Electronic files take up much less physical space, allow for easier access, and enable quick backup. As a result, many businesses manage their records almost entirely electronically.

These records allow companies to both prepare their tax returns and prove the return's accuracy during tax audits. The IRS and other tax authorities can deny deductions for unsubstantiated expenses, potentially leading to interest and penalties.

How long should businesses keep tax returns and other business tax records?

Fortunately, the IRS cannot assess additional tax once the statute of limitations has passed. The federal income tax statute of limitations is as follows:

• three years from the filing date—or the due date, if later—for most tax returns
• four years after the tax becomes due—or gets paid, if later—for employment tax returns
• six years from the filing date—or the due date, if later—for tax returns that underreport gross income by more than 25%
• seven years from the filing date—or the due date, if later—of the related tax returns for losses from worthless securities or bad debt
• Forever for unfiled or fraudulent tax returns

Some state taxing authorities follow IRS rules, while others use different periods. Creditors and investors may have their own requirements.

Creating different retention policies for each possible scenario may prove impractical. Retaining tax returns and other records for seven years—starting from the later of the filing date and due date of the related tax return—offers a convenient rule of thumb.

Many CPA firms and other tax practitioners retain tax records for seven years, though some keep them indefinitely in digital storage. Even businesses that entrust their records to a certified tax professional need to keep copies. The IRS and other taxing authorities can deny deductions that a company can't support, even if an outside professional lost the documentation. However, CPAs cannot deliberately withhold records, even for unpaid fees.

Business tax records to keep forever

Companies must keep certain tax records indefinitely. Assets usually have tax consequences upon sale, so you should keep records relating to the asset until the statute of limitation expires for the year in which the sale took place.

Company formation documents and ownership records such as stock ledgers, titles, deeds, property records, contracts, bylaws, and meeting minutes should be retained permanently.

Failure to maintain corporate records could cause the corporation's owners to lose liability protection.

Missing documentation can cause substantial liability and missed opportunities. Keeping tax returns and other records for the appropriate period allows your business to respond to information requests, including tax audits.
