Yes, the IRS accepts digital receipts — and has since 1997 under Revenue Procedure 97-22. As long as your scans are accurate, legible, and retrievable, they satisfy federal recordkeeping requirements. The confusion persists because most people never look up the actual rule, and the rule itself is almost 30 years old — so old that a lot of tax advice articles still treat digital records as some kind of risky innovation. They are not.
This guide walks through what the rule actually says, what "adequate records" means under the tax code, how long you actually need to keep receipts, and what situations still benefit from keeping paper.
One note before we start: we are the team behind a document scanner app, not tax professionals. This post is general information drawn from publicly available IRS publications and revenue procedures. It is not tax advice. For your specific situation, talk to a CPA.
The rule: Revenue Procedure 97-22
The legal authority for keeping tax records in electronic form in the United States is Revenue Procedure 97-22, issued by the Internal Revenue Service in 1997. It established that taxpayers may maintain records required under the Internal Revenue Code in an electronic storage system, provided certain conditions are met.
The key requirement: the electronic system must preserve records in a way that ensures they can be retrieved, reproduced, and are legible when reviewed. In the IRS's own words, the system must "ensure an accurate and complete transfer of the hardbooks and records to an electronic storage media" and the reproduced records must have "a high degree of legibility and readability."
In plain English: if the digital copy is accurate, legible, and can be produced on request, the IRS treats it the same as the paper original.
Rev. Proc. 97-22 also requires that the electronic storage system be tested and maintained, that you be able to reproduce hard copies when the IRS requests them, and that the system have reasonable controls to ensure integrity. For an individual filer using an iPhone scanner app like ScanLens, this mostly means: pick something reliable, keep your backups current, and make sure the files can still be opened in a few years.
The IRS has explicitly allowed electronic recordkeeping since 1997. Most of the confusion about whether scanned receipts "count" exists because people are answering a 1995 question with 2026 facts.
What counts as "adequate records" for deductions
Rev. Proc. 97-22 covers the format — electronic instead of paper. Separately, IRS Publication 463 (Travel, Gift, and Car Expenses) and the Internal Revenue Code cover the content — what you actually need to document. The two are independent. You can have a perfectly legal electronic storage system full of inadequate records.
For business expense deductions, the IRS expects you to substantiate each deduction with records showing:
- The amount — what was spent
- The time — the date the expense was incurred
- The place — where the expense happened (relevant for travel and meals)
- The business purpose — why it counts as a business expense
A scanned receipt typically shows the amount, date, and place automatically. The business purpose is the part people forget. For a $12 client lunch, a clean scan of the receipt is not enough on its own — you also need something that records who you met with and why. This could be a note in your expense tracker, a line in your calendar, or a comment added to the scan itself. In ScanLens, you can annotate each scan with a note right after capture, which is the easiest way to record the business purpose while you still remember it.
This is worth emphasizing because it is where audits actually go sideways. The IRS does not usually question whether your receipt is a scan or a photocopy. It questions whether you can document why the expense was deductible. The scan format is not the problem; the missing context is.
The $75 rule (and its limits)
A detail that often gets mentioned: under IRS Publication 463, you generally do not need a receipt for business expenses under $75, except for lodging. You still need to document the amount, time, place, and business purpose — you just do not need the physical receipt.
This is frequently misinterpreted as "you do not need to track small expenses." That is wrong. You still need contemporaneous records. You just do not necessarily need a receipt to back them up. An account log, calendar entry, or mileage log can satisfy the requirement for expenses under $75.
In practice, for anyone scanning receipts: scan everything anyway. Storage is cheap. The $75 rule is a floor for what the IRS requires, not an argument for doing less.
How long do you need to keep receipts?
The retention period depends on what kind of return you filed and what is on the receipt. The IRS publishes these periods in various publications; they have been consistent for many years.
Standard return
Keep records for 3 years from the date you filed the return or 2 years from the date you paid the tax, whichever is later. This is the standard audit window for most returns without issues.
If you understated income by more than 25%
Keep records for 6 years. The extended audit window applies when the IRS has reason to believe substantial income was omitted.
If you filed a fraudulent return or did not file
No statute of limitations. Keep records indefinitely. (If this applies to you, talk to a tax attorney, not a blog.)
Employment tax records
Keep for at least 4 years after the tax becomes due or is paid, whichever is later.
Records for property
Keep until the period of limitations expires for the year you disposed of the property. If you bought a house in 2010 and sold it in 2024, you keep records from 2010 at least until the statute of limitations for 2024 runs out.
The practical rule most accountants give: keep everything tax-related for 7 years. That covers the standard window, the extended window, and gives you a safety margin. Digital copies make this cheap. A thousand scanned PDFs takes less space than a single file folder.
What about state taxes?
State tax authorities in the US generally follow similar rules — they accept electronic records, and their retention windows are usually the same as or slightly longer than the federal window. A few states have longer retention requirements for specific types of records, and some state audits reach back further for state-specific issues. If you file state returns, 7 years of digital archive is still the conservative answer.
Outside the United States, other tax authorities have their own rules. HMRC in the UK accepts digital records in most cases under similar "accurate, accessible, legible" standards. The Canada Revenue Agency accepts scanned images if they are legible and readable. Most modern tax authorities have caught up to 1997 by now.
What scanning workflow actually satisfies the IRS
The minimum viable workflow for a self-employed filer or small business:
- Scan each receipt within a few days of getting it (while the ink is still legible — thermal-paper receipts fade)
- Capture the full receipt, including any fine print or reverse side if it has relevant information
- Store the scan in a way you can still access in 7 years (cloud sync or local backup)
- Add a note recording the business purpose if it is not obvious from the receipt itself
- Tag or file by tax category so you can produce them if asked
ScanLens is built for exactly this workflow — on-device scanning, auto-upload to your own cloud, searchable OCR so you can find a specific receipt across thousands, and tags to keep categories straight. The Receipt Scanner feature page covers the app-specific details.
But the workflow matters more than the specific tool. Any reliable scanner app plus any stable cloud storage is enough. The failure mode that causes problems is not "I used the wrong app." It is "I meant to scan things and then got busy and now the receipt is faded beyond recognition."
When paper originals still matter
Rev. Proc. 97-22 applies to records required under the Internal Revenue Code. Most receipts fall under this. A few things that commonly end up in "receipt piles" do not, and benefit from paper originals:
- Title documents for major property — vehicle titles, real estate deeds, stock certificates (rare but real)
- Certain government-issued documents with raised seals or watermarks — birth certificates, court orders
- Original wills and trust documents — though these are typically separate from receipt-keeping
- Any document explicitly required to be kept in original form by a specific statute
Our companion post on which documents to keep as paper originals covers this in more depth. For routine tax receipts — meals, travel, supplies, medical expenses, charitable donations — digital is not just acceptable, it is actually better because it is more durable than thermal paper.
The common misconception
The confusion we most often hear is from people who have heard "the IRS wants paper" from a friend or relative or an outdated article. This was not true when Rev. Proc. 97-22 came out in 1997, and it is even less true now. The IRS itself uses electronic records extensively for audits and correspondence. The form of the record has not mattered for nearly three decades.
The things that actually matter in an audit are the things that have always mattered: can you produce the record, is it legible, and does it show the required information (amount, date, place, purpose). Whether it is on paper, on your phone, or in a cloud folder is not the question the auditor is asking.
The IRS has explicitly allowed electronic storage of tax records since 1997 under Rev. Proc. 97-22. As long as your scans are accurate, legible, and retrievable, they satisfy the recordkeeping requirement. Keep them for at least 7 years, include enough context to document the business purpose, and use whatever scanning tool you actually stick with.
