How Long to Keep Receipts for Business: IRS Rules and Penalties

For most business receipts, the answer is three years from the date you filed the tax return the receipt supports, or the return’s due date if that falls later. That is the floor. How long to keep business receipts beyond that floor depends on what the receipt documents: payroll records run four years, bad debt write-offs run seven, records tied to business property have to survive until you sell the property and then some, and a handful of documents never get thrown away. Get the category wrong and you can lose a legitimate deduction simply because you shredded too soon.

Why Three Years Is the Starting Point

The IRS generally has three years from the date you file a return to assess additional tax on it.¹ Every receipt, invoice, canceled check, and bank statement that backs up a number on that return should still be reachable during that window. If an examiner questions a deduction and you can hand over the underlying paperwork, the deduction stands. If you can’t, it doesn’t.

Two things can stretch that three-year window. First, if you omit more than 25% of the gross income you should have reported, the assessment period doubles to six years.¹ The IRS describes the same rule less formally on its audit page: a “substantial error” can push the lookback out, typically as far as six years.² Second, there’s no time limit at all on a fraudulent return, a willful attempt to evade tax, or a return that was never filed. In practice that means the records tied to any problem year need to live indefinitely.

Records That Need to Stay Longer

Property, Equipment, and Vehicles

Anything you depreciate or claim basis in has to be kept for as long as you own it, plus the assessment period on the return that reports the sale or disposal. IRS Publication 583 states this plainly: hold property records until the limitation period expires for the year you dispose of the asset.³ Buy a piece of equipment in 2020, sell it in 2030, and you need the original invoice and every depreciation schedule available through at least 2033. For a building held two decades, you are keeping the purchase closing packet for 25 years or more.

Payroll and Employment Tax

Wage records, withholding, and FICA documentation carry a four-year hold measured from the date the tax was due or the date it was paid, whichever comes later.⁴ The four years covers all employment taxes, not just income tax withholding.⁵

Bad Debts and Worthless Securities

Here is the one that catches people. If your business writes off a bad debt or claims a loss on worthless securities, the period for filing a refund claim tied to that loss runs seven years from the return’s due date, not the usual three.⁶ Publication 583 confirms the seven-year hold in its retention table.³ Keep the loan documents, the collection attempts, and whatever evidence supported the worthlessness determination for the full seven years.

Employee Benefit Plans

If you sponsor a retirement plan, health plan, or other ERISA-covered benefit plan, the floor is six years after the filing date of the plan’s annual Form 5500, or the date it would have been filed.⁷ The statute wants enough underlying detail on hand — vouchers, worksheets, receipts, resolutions — to verify what was filed. Records used to compute benefits owed to current or former participants often need to survive well past six years, because they stay relevant as long as a claim could come in.

Form I-9

Every employee hired after November 6, 1986 needs a completed Form I-9 on file. Retention: three years after the date of hire, or one year after employment ends, whichever is later.⁸ For someone who worked under two years, use the three-year-from-hire measure. For anyone longer-tenured, use the one-year-after-termination measure.

Formation and Ownership Documents

Articles of incorporation, operating agreements, bylaws, meeting minutes, and the paperwork from buying or selling the business itself should be kept permanently. They establish the entity’s legal existence and its ownership, and none of that is tied to a single tax year.

What a Receipt Has to Show

A receipt that survives the retention period but omits key details won’t save the deduction. Supporting documents need to identify the payee, the amount, proof of payment, the date of the expense, and a description showing the item or service was a legitimate business expense.⁵ A faded credit card slip with just a merchant name and a dollar figure often falls short.

Travel, business gifts, and listed property (vehicles are the common example) face a stricter rule under Section 274. You have to document four elements: amount, time and place (or date and description for gifts), business purpose, and the business relationship of the person receiving the benefit.⁹ These notes need to be made at or near the time of the expense. A log rebuilt from memory months later carries much less weight in an audit than contemporaneous notes.

What that looks like in practice: on a business lunch receipt, jot the restaurant, date, amount, who attended, and what you discussed. For a vehicle, log the date, destination, business purpose, and miles for each trip. Build the habit into the moment of the expense and the recordkeeping mostly handles itself.

State Rules Can Push the Floor Higher

State tax agencies run their own assessment clocks, and they don’t uniformly match the federal three-year period. Many states use four years for income tax. Sales and use tax lookback windows across the states range from three to six years, most often three. States commonly extend those periods when there’s significant underreporting, and most drop the time limit entirely for fraud or non-filing.

If you operate or collect tax in more than one state, identify the longest applicable period across every jurisdiction and retain to that number. A business with a four-year sales tax window in one state and a three-year income tax window in another should default to four for overlapping records. State unemployment insurance recordkeeping typically runs four years too, though it varies from three to seven depending on the state.

What It Costs to Come Up Empty

If you can’t produce documentation for a claimed deduction, the deduction is disallowed and the resulting underpayment typically draws an accuracy-related penalty of 20%.¹⁰ That penalty applies where the IRS finds negligence or a substantial understatement of income tax. Substantial means an understatement greater than the larger of 10% of the correct tax or $5,000.¹¹ Persistent failures can produce a formal Notice of Inadequate Records, and willful failure to keep required records is a criminal offense under the tax code.¹² The civil math alone is punishing: a $50,000 deduction thrown out for missing receipts can add $10,000 or more in penalty on top of the extra tax, with interest running from the original due date.

One partial safety net exists. Under the Cohan rule, a longstanding court-created principle, taxpayers can rely on reasonable estimates when actual records are destroyed by fire, flood, or another event outside their control, provided there’s some factual basis for the estimate. A bank statement showing payment to a known supplier plus testimony about the purchase might get you a partial deduction without the original receipt. The critical limit: Cohan does not apply to travel, business gifts, or listed property. Those fall under Section 274’s strict substantiation rule, and no records means no deduction.⁹ Mileage logs and travel notes deserve extra backup for exactly this reason.

Digital Copies Are Fine, With Conditions

The IRS accepts scanned and electronic records in place of paper originals as long as the digital copies are accurate, complete, and clearly legible.¹³ You can shred paper after scanning, provided your storage system protects the integrity of the files, prevents unauthorized changes, and can produce readable copies on demand. Cloud storage and local servers both qualify.

The practical version: scan into a folder structure with consistent file names (date, vendor, amount), keep a backup in a second location, and check every so often that you can actually find and open what you saved. Ten thousand images dumped into one directory with no index will not help you when an examiner asks for the receipts behind a specific expense category.

Quick Reference

These are minimums. When in doubt, round up.

3 years — general business receipts, expense records, and income documentation, measured from the filing date or the return’s due date, whichever is later.³
4 years — employment tax records (wages, withholding, FICA) from the date the tax is due or paid, whichever is later.⁴
6 years — returns where income was underreported by more than 25%; ERISA benefit plan records from the Form 5500 filing date.⁷
7 years — records supporting bad debt deductions or losses from worthless securities.³
Life of asset plus 3 years — purchase records, improvement costs, and depreciation schedules for business property, held until the assessment period expires for the year of disposal.³
Indefinitely — corporate formation documents, ownership records, and anything tied to a return that was fraudulent or never filed.¹
