How Long to Keep Business Tax Records: IRS Requirements and Practical Guidelines
The IRS requires businesses to keep records that support the income, deductions, and credits reported on the tax return. The retention period depends on the type of record and the applicable statute of limitations. The general rule is 3 years from the filing date (the standard audit statute), but certain situations extend the requirement to 6 or 7 years, and some records should be kept permanently.
Retention periods by record type:
Keep for 3 years (standard audit statute):
- Income records (bank deposits, invoices, 1099s received)
- Expense records (receipts, credit card statements, cancelled checks)
- Quarterly payroll reports (Form 941)
- Sales tax returns
- General ledger and journals
Keep for 6 years (25% understatement rule):
- All records for years where income may have been underreported by more than 25% of gross income (the IRS has 6 years to audit in this case)
- Practically: keep all income and expense records for 6 years for added safety
Keep for 7 years:
- Records supporting a bad debt deduction or worthless securities claim (the statute is 7 years for these deductions under IRC 6511(d))
Keep permanently:
- Tax returns (federal and state)
- Entity formation documents (articles of incorporation, operating agreements)
- Asset purchase records (cost, date, depreciation schedules) for as long as the asset is owned, plus 3 years after disposition
- Real estate records (purchase price, improvements, closing statements) for as long as the property is owned, plus 3 years after sale
- Retirement plan documents (plan adoption agreements, annual contribution records, Form 5500 if applicable)
- Employment tax records (W-2s, W-4s, payroll registers)
Why do asset records need to be kept so long?
Depreciation and basis records must be maintained for as long as the asset is owned, plus 3 years after the asset is sold or disposed of. If a business purchases equipment in 2020 and sells it in 2030, the business needs the 2020 purchase records to calculate the depreciation recapture in 2030. If the IRS audits the 2030 return, the business must prove the original cost and the depreciation taken over the 10-year holding period.
For real estate, the records can span decades. A rental property purchased in 2005 and sold in 2035 requires 30+ years of records: the original purchase closing statement, every improvement receipt, the annual depreciation calculations, and the sale closing statement.
What’s the best way to store records?
The IRS accepts digital records as long as they’re legible and accessible. Scanning paper receipts and storing them digitally (cloud storage, accounting software) is sufficient. The original paper receipt doesn’t need to be retained if a clear digital copy exists.
For small businesses, the practical approach:
- Use accounting software (QuickBooks, Xero) that stores transaction records digitally
- Scan or photograph receipts and attach them to transactions in the software
- Keep bank and credit card statements in digital form (most banks provide online access for 7+ years)
- Store tax returns (PDF) in a permanent digital archive (cloud backup)
- Keep a physical folder for entity documents, real estate closing statements, and retirement plan documents
The cost of over-retaining records (keeping them 7 years instead of 3) is minimal with digital storage. The cost of under-retaining (destroying records that are later needed for an audit) can be substantial.
How do I choose the right tax professional for my business?
Look for a CPA or enrolled agent (EA) with experience in your specific industry and business structure. CPAs are state-licensed and must meet continuing education requirements. EAs are federally licensed and specialize in tax representation before the IRS. Ask about their experience with businesses of your size and type, their availability during off-season for planning, and whether they handle IRS notices and audits. Avoid preparers who promise unusually large refunds or base their fee on a percentage of your refund. A good tax professional will proactively identify planning opportunities, not just prepare the return after the year ends.
What is the qualified business income deduction under Section 199A?
The Section 199A deduction allows eligible self-employed taxpayers and pass-through business owners to deduct up to 20% of their qualified business income from their taxable income. For taxable income below the threshold ($191,950 single, $383,900 married filing jointly in 2024), the deduction is simply 20% of QBI with no additional limitations. Above the threshold, specified service trades or businesses (SSTBs), including accounting, law, health, consulting, and financial services, face a phase-out that completely eliminates the deduction at $241,950/$483,900. Non-SSTB businesses above the threshold are limited by the greater of 50% of W-2 wages paid OR 25% of W-2 wages plus 2.5% of the unadjusted basis of qualified property. This deduction is scheduled to expire after December 31, 2025, unless Congress extends it.
