For a US business, the federal baseline is set by the Internal Revenue Service (IRS): keep every record that supports an item of income, deduction, or credit on a filed tax return until the period of limitations for that return expires — generally 3 years after filing, at least 4 years for employment tax records, 6 years if more than 25% of gross income was omitted, 7 years for bad-debt or worthless-securities claims, and indefinitely if no return was filed or a return was fraudulent. That applies to sole proprietors, partnerships, limited liability companies (LLCs), and corporations alike. The biggest limitation: federal periods are a floor, not a ceiling — states, employee-benefit law, lenders, and insurers can require you to keep records longer.

Quick answer

US businesses should keep tax-supporting records (receipts, invoices, bank statements, ledgers) for at least 3 years after filing the related return, employment tax records for at least 4 years after the tax is due or paid, and property records until the period of limitations expires for the year the property is sold or disposed of. Payroll records add separate Department of Labor (DOL) periods: 3 years for payroll records under the Fair Labor Standards Act (FLSA) and 2 years for time cards and other wage-computation records. Digital copies are acceptable to the IRS if your storage system can index, store, preserve, retrieve, and reproduce them legibly.

What records does the IRS expect a US business to keep?

Federal tax law does not force one specific filing system on you. The IRS recordkeeping guidance lets you choose any system that clearly shows your income and expenses — but the responsibility for proof stays with you:

“The responsibility to substantiate entries, deductions, and statements made on your tax returns is known as the burden of proof.” — Internal Revenue Service

Your system needs two layers: a summary of transactions (your books — journals, ledgers, or accounting software) and the supporting documents behind each entry. The IRS page on what kinds of records to keep lists the categories:

Gross receipts — cash register tapes, deposit records, receipt books, invoices, Forms 1099-MISC.
Purchases — canceled checks or other proof of payment, cash register tape receipts, credit card receipts and statements, invoices identifying payee, amount, date, and item.
Expenses — the same document types, showing what was bought and that it was for business.
Travel, gift, and transportation expenses — these carry extra substantiation elements under IRS Publication 463.
Assets — acquisition date and method, purchase price, improvements, section 179 and depreciation deductions taken, use, disposal date, and selling price.
Employment taxes — the specific records covered below.

Keep copies of your filed tax returns indefinitely; the IRS notes they help prepare future and amended returns. One framing note: these retention periods are legal minimums under tax and labor law — not accounting standards. Your US Generally Accepted Accounting Principles (GAAP) statements and management reports draw on the same documents, but the retention clock comes from the IRS and DOL, not from GAAP.

How long must you keep each type of record?

The IRS period-of-limitations rules are the anchor. The periods below are the federal baselines published by the IRS, DOL, and related agencies as of July 2026 (accessed July 27–28, 2026).

Table 1: Federal record-retention periods by record type (US federal baseline).

Record type	Minimum retention period	Source
Records supporting income, deductions, or credits on a filed return	3 years after the return was filed (if no special situation below applies)	IRS
Records supporting a claim for credit or refund filed after the return	3 years from filing or 2 years from the date tax was paid, whichever is later	IRS
Records for a year where unreported income exceeds 25% of gross income shown	6 years	IRS
Records supporting a bad-debt deduction or worthless-securities loss claim	7 years	IRS
Any records for a year with no return filed, or a fraudulent return	Indefinitely	IRS
Employment tax records (Forms 941/940 support, W-4s, deposit records)	At least 4 years after the tax becomes due or is paid, whichever is later	IRS
Property and asset records (basis, improvements, depreciation)	Until the period of limitations expires for the year you dispose of the property	IRS
FLSA payroll records, collective bargaining agreements, sales and purchase records	At least 3 years	DOL Fact Sheet 21
Time cards, piece-work tickets, wage rate tables, work schedules, wage addition/deduction records	2 years	DOL Fact Sheet 21
Family and Medical Leave Act (FMLA) leave records	No less than 3 years	29 CFR 825.500
Personnel and employment records under Equal Employment Opportunity Commission (EEOC) rules	1 year (1 year from termination if involuntary); until final disposition once a charge is filed	EEOC
Employee benefit plan records under the Employee Retirement Income Security Act (ERISA)	At least 6 years after the filing date	29 USC 1027

Interpretation: the practical rule of thumb is 4 years for anything payroll-related and 3 years for everything else supporting a filed return — with property records parked until the disposal year’s window closes, and nothing destroyed while an audit, charge, or dispute is open. When two periods overlap, the longest one wins.

Payroll sits under two agencies at once. DOL’s FLSA recordkeeping fact sheet instructs:

“Each employer shall preserve for at least three years payroll records, collective bargaining agreements, sales and purchase records.” — U.S. Department of Labor, Fact Sheet 21

The IRS 4-year employment-tax rule runs longer, so payroll files default to the IRS period.

When does the retention clock actually start?

The start date is the part most owners get wrong: the clock does not run from the transaction date or from December 31. The IRS period-of-limitations guidance states that the years “refer to the period after the return was filed,” and that returns filed before the due date are treated as filed on the due date. Employment tax records run from when the tax became due or was paid, whichever is later, and property records run to the end of the limitations period for the disposal year’s return.

Worked example (hypothetical illustration with made-up inputs). A fictional calendar-year sole proprietor, “Jordan,” files the 2025 Form 1040 with Schedule C on March 10, 2026 — five weeks before the April 15, 2026 due date.

Inputs: tax year 2025; return filed March 10, 2026; due date April 15, 2026; no special situations.
Method: a return filed before its due date is treated as filed on the due date, so the clock starts April 15, 2026. Add each limitations period to that start date.
Output: the 3-year baseline expires April 15, 2029 (April 15, 2026 + 3 years). If more than 25% of gross income had been omitted, the window would run to April 15, 2032 (+ 6 years); a bad-debt claim would extend support to April 15, 2033 (+ 7 years).
Property variant: Jordan bought a machine for $18,000 in 2022 and sells it in 2026. The purchase invoice and improvement receipts must stay until the limitations period expires for the 2026 return — filed on time April 15, 2027, so April 15, 2030 (April 15, 2027 + 3 years) — eight years after the purchase.
Payroll variant: employment tax records for first-quarter 2025 wages (Form 941 due April 30, 2025) must be kept at least until April 30, 2029 — 4 years after the due-or-paid date, whichever is later.

Interpretation: filing early does not start the clock early, and buying an asset starts a clock that only stops after you sell. Keying your schedule to “return filed date + period” per tax year is the only reliable way to compute destruction dates; a flat “3 years from year-end” rule destroys some records too early.

Can you go paperless? Digital-copy controls that satisfy the IRS

Yes — the IRS accepts electronic records, but the substitution is conditional. IRS Publication 583, Starting a Business and Keeping Records, is explicit:

“All requirements that apply to hard copy books and records also apply to electronic storage systems that maintain tax books and records.” — IRS Publication 583

The same publication requires an electronic storage system to “index, store, preserve, retrieve, and reproduce the electronically stored books and records in legible format,” maintained for as long as the records are material to the administration of tax law. Turned into controls, a defensible paperless setup needs:

Legibility and completeness — scans or native files capture the whole document at readable quality.
Indexing and retrieval — any specific record can be located on request by date, vendor, account, or tax year.
Preservation and backup — records survive device failure and software changes; export data before a system overwrites it. California’s sales tax Regulation 1698 makes exactly this point for point-of-sale systems that overwrite data inside the retention window.
Producibility — you can deliver readable copies to the IRS or a state agency on request.
Integrity — access controls and audit trails limit who can alter or delete stored records.

Shredding paper originals is reasonable only after the digital system demonstrably meets these tests.

When do states or other rules require you to keep records longer?

The federal table is a floor. Three extensions matter most:

State tax agencies. States set their own retention periods for sales, payroll, and income tax records, and they do not all match the IRS 3-year baseline. California, for example, requires sales and use tax records to be preserved for “a period of not less than four years” unless the agency authorizes earlier destruction in writing, under Regulation 1698 (Business Taxes Law Guide, Revision 2026; accessed July 28, 2026). The Small Business Administration (SBA) hiring guide likewise tells employers to learn which records must stay on file and for how long, and to check state tax agency rules. Check every state where you file.
Benefit plans and employment charges. ERISA-covered plan records run 6 years from filing (29 USC 1027), and once an EEOC charge is filed, related personnel records must be kept until final disposition — whatever the normal 1-year period says.
Contracts, lenders, and insurers. The IRS itself warns: “your insurance company or creditors may require you to keep them longer than the IRS does.” Loan covenants, bonding, and grant terms can add years.

And one universal override: never destroy records that relate to an open audit, charge, dispute, or refund claim, regardless of what the schedule says.

How do you turn this into a document retention policy?

A written policy converts the tables above into destruction dates you can defend. Six steps:

Inventory your record types — bank statements, invoices, receipts, payroll registers, time records, tax returns, asset documents, contracts, benefit-plan filings.
Assign each type its longest applicable period — Table 1 plus your states’ periods; where periods conflict, the longest wins.
Tag property records to the disposal year — the retention end date is computed from the return for the year you sell or retire the asset, not the purchase year.
Set the digital controls — indexing, legibility, backup, overwrite exports, producibility.
Log destructions — record what was destroyed, the tax years covered, and the date, so a missing file is explainable rather than suspicious.
Review annually and freeze when needed — re-check the schedule each year and suspend all destruction during any audit, agency charge, or dispute.

Retention is also the foundation that makes audit response possible: this page covers how long to keep the evidence, while our audit-readiness checklist for small businesses walks the preparation workflow, and the separate guide to red flags that can trigger an IRS audit covers what draws scrutiny.

FAQs

Does the 3-year rule mean I can shred everything after three years?

No. Three years is only the default: 6 years applies if you omitted more than 25% of gross income, 7 years for bad-debt or worthless-securities claims, 4 years minimum for employment tax records, and property records run until the disposal year’s window closes. State or contract rules can extend any of these, and nothing should be destroyed while an audit, charge, or dispute is open.

Are scanned receipts acceptable to the IRS?

Yes, if your electronic system meets the same requirements as paper — it must index, store, preserve, retrieve, and reproduce records legibly, maintained as long as the records are material to the tax law, per IRS Publication 583. A shoebox of unlabeled phone photos does not meet that standard; an organized, backed-up document system does.

How long should I keep payroll records?

Use 4 years as the working federal rule: the IRS requires employment tax records for at least 4 years after the tax becomes due or is paid (whichever is later), the FLSA requires 3 years for payroll records and 2 years for time cards and wage-computation records, and FMLA leave records run 3 years. State agencies may require longer.

What happens if I cannot produce records during an audit?

The burden of proof sits with you, not the IRS. Deductions you cannot substantiate can be disallowed, which increases tax — and potentially interest and penalties — for the year under examination. That is why the retention schedule matters more than the storage format.

Do I still need records after I close or sell the business?

Yes. The limitations periods run on the returns you already filed, not on whether the business still operates. Keep records until each relevant window closes — including property records, which run until the disposal year’s period expires — and confirm any buyer or successor obligations in the sale agreement with your advisors.

The bottom line

Compute destruction dates as “return filed date (or due date, if earlier-filed) plus the longest applicable period,” default to 4 years for payroll and 3 years for everything else, park property records until the disposal year’s window closes, and hold digital records to the same legibility, indexing, and retrieval standard as paper. If your receipts, payroll files, and bank records are scattered across inboxes and apps, the first step is getting them organized with clear retention tags — our remote bookkeeping services help US businesses set up exactly that kind of organized finance-record system.
