Recordkeeping Rules: How Long to Keep Different Tax Documents

Quick answer

Most taxpayers should keep tax records for at least three years after the date they file the return or the due date, whichever is later. That three‑year rule is the baseline; several common exceptions require longer retention (for example, six years if you underreport income by 25% or more, or indefinitely if you filed fraudulently or never filed). These timelines and examples follow IRS guidance (see IRS Recordkeeping page and Publication 552) and reflect common practice in tax compliance.

Why retention rules matter

Good recordkeeping is not just busywork. Records prove the income, deductions, credits, and basis figures on which your tax return is built. In my work advising clients, cases where taxpayers kept tidy, searchable records lead to faster, more favorable audit outcomes than cases with missing or disorganized files. Proper retention also reduces the risk of identity theft and makes it easier to respond to lenders, insurers, or government agencies asking for proof of income or expenses.

How long to keep common documents (practical chart)

Below are commonly used retention periods that reflect IRS rules and good practice. Keep in mind these are minimums—if you have an ongoing matter, carry the records until it’s resolved plus the statutory period.

Special situations that change retention time

• Underreported income: If you understate gross income by more than 25%, the IRS can examine returns back six years (IRS Pub. 552).
• Fraud or failure to file: No statute of limitations—retain records indefinitely. In my practice, I advise clients with earlier irregularities to keep records until any IRS matters are fully closed.
• Loss, casualty, or bad debt claims: Keep records until the period of limitations for those claims ends, often three to six years depending on the claim.

(See IRS Publication 552 and the general Recordkeeping guidance for details.)

Digital copies: are scanned records acceptable?

Yes. The IRS accepts electronic records if they are accurate, readable, and retrievable for the required period. That means scans or digital photos must be legible and stored in an organized system so you can produce them quickly if needed (IRS Recordkeeping page). When converting paper to digital, keep the following in mind:

• Scan at a high enough resolution to read signatures, numbers, and dates.
• Save files with clear, consistent file names and folder structure.
• Keep an index or searchable system (for example, tags or a spreadsheet catalog).
• Back up your records using a second medium or a secure cloud provider that keeps version history.

In my experience, clients who use hardened cloud storage and a simple naming convention (YearTypePayer_Amount) find it much easier to gather documents for audits or loan applications.

How to organize records so you can find them fast

• Keep a single filing system (physical or digital) by tax year.
• Keep an audit file: copies of the filed return, schedules, worksheets, and supporting receipts grouped together.
• Keep payroll and employment files separate and label them by employee and year.
• Use tax software or a spreadsheet that references documents by file name and date.

What to do when the IRS contacts you

If you receive a notice or audit request:

1. Read the notice carefully and note the deadline.
2. Gather the documents requested from the relevant tax year(s). Your organized audit file will save you time.
3. Provide copies, not originals, unless the IRS specifically requests originals.
4. If you can’t find a document, explain why and provide substitute records if available (bank statements, canceled checks, credit card records).

If you’re uncertain about a response, consult a tax professional; they can prepare a response packet and represent you before the IRS.

Safe disposal and privacy protection

After the required retention period you can destroy sensitive tax documents—but do it securely. Shred paper records or use a secure document destruction service. For digital files, delete securely and overwrite or use tools that meet secure-deletion standards. Keep in mind that identity thieves can use old W-2s, social security numbers, and bank statements.

Real-world examples (brief)

• Individual filer: A taxpayer who kept receipts and bank records for charitable donations provided substantiation during an IRS correspondence audit and avoided disallowed deductions. Without documentation, similar taxpayers often face denied deductions and added tax.
• Small business: A client who kept organized invoices, mileage logs, and payroll documents was able to substantiate business expenses during a field audit, reducing exposure and closing the audit quickly.

Common mistakes to avoid

• Keeping everything forever—creates clutter and increases the risk of exposure if data is breached.
• Destroying records too soon—especially property basis or documents tied to ongoing disputes.
• Poor digital backups—don’t rely on a single device. Use encrypted cloud storage plus a local backup.

FAQs (short)

Q: Can I destroy my tax return after three years? A: You can destroy copies of the return after the statute for that year expires, but keep any documents that support items reported on later returns (like property basis) until those later years’ limitations expire.

Q: Are digital receipts acceptable for charitable gifts? A: Yes, digital receipts and donor letters are acceptable if they contain the required information. For larger noncash gifts, follow the substantiation rules in IRS guidance.

Q: Should I keep transaction-level banking records? A: Keep them long enough to substantiate items on your tax return—three years is usually enough unless a transaction affects basis or triggers the longer look-back periods.

Final practical checklist

• Keep tax returns and related records for at least 3 years.
• Keep employment-related tax records for at least 4 years.
• Keep records for 6 years if you underreported gross income by >25%.
• Keep records indefinitely for fraud or if you never filed.
• Convert paper to high-quality digital copies, back them up, and catalog them.
