Record retention is treated as a filing question and it is really an asset question, which is why the usual rules of thumb get people into trouble.
Most records can be discarded after a period tied to how long a return can be examined. A smaller set cannot, because it establishes what you paid for something you still own, and that position is only settled when the asset is eventually sold.
This covers the general periods, what the guidance actually says, the records that should be treated as permanent, how investment cost records work, whether digital copies are acceptable, and what can safely go.
Why Record Retention Matters
The IRS can audit your return within a defined window. If audited, you need documentation to support every item on your return. Without records, you lose deductions even if you actually incurred them.
Anything that establishes what you paid for something you still own is not subject to a retention period at all. The cost of a property, the improvements since, the purchase price of shares: those decide a position that will only be settled when the asset is sold, which may be decades away.

IRS Guidance Explained
3-Year Minimum
The standard IRS audit window is 3 years from your filing date or return due date, whichever is later. Keeping records for 3 years is the bare minimum.
6-Year Extended Window
If you underreported income by more than 25%, the IRS has 6 years. Keeping records for 7 years covers this window with a buffer.
No Limit: Fraud or Unfiled Returns
If you never filed a return for a year, or filed a fraudulent return, there is no statute of limitations. The IRS can assess tax at any time. If you have years with unfiled returns, consult a tax professional.
Property Records: A Special Case
Keep records of:
- Original purchase price (closing disclosure / HUD-1)
- All capital improvements (new roof, addition, renovation with receipts)
- Casualty losses taken as deductions
- Depreciation taken if the property was used in a business
These records affect your cost basis when you sell, which determines your taxable gain. Keep them until 3 years after the year of sale.
Investment Records: Cost Basis
For every investment you own, keep:
- Trade confirmation or brokerage statement showing purchase date and price
- Records of stock splits and dividends reinvested
- Records of spin-offs or mergers that affected your cost basis
Brokerage firms are required to report cost basis to the IRS for covered securities (generally purchased after 2011). For older holdings, your personal records may be the only evidence of cost basis.
Foreign Assets and FBAR Records
If you have foreign bank accounts or assets, keep records for at least 6 years (matching the FBAR civil assessment window). This includes account statements, foreign tax returns, and transfer records.
Digital Storage: Is It Acceptable?
Yes. The IRS accepts digital copies of records if they are:
- Legible and accessible
- Reproducible on paper if requested
- Stored in a secure and backed-up location
Best practice: scan receipts and documents immediately. Physical paper deteriorates. Store digital copies in cloud storage (Google Drive, Dropbox, OneDrive) and a local backup.
What You Can Safely Discard After 7 Years
- Utility bills not used as deductions
- Bank statements (if not supporting a deduction)
- Credit card statements for personal expenses
- Old pay stubs (after reconciling with your W-2)
- Routine business receipts not tied to a specific deduction

Frequently Asked Questions
Do I need to keep the original paper return?
No. A digital scan or copy is acceptable. The IRS accepts electronic records. Keep both federal and state returns.
My tax software stores my returns. Is that enough?
It is a good start, but do not rely solely on third-party software. Download a PDF copy of every return and store it yourself. Software companies can change their policies or go out of business.
What if I made a major renovation but lost the receipts?
Reconstruction is possible using contractor invoices, credit card statements, or permits filed with the municipality. Start reconstructing the record as soon as you realize it is missing.
How long should a business keep payroll records?
Employment tax records (payroll registers, I-9 forms, withholding records) must be kept for 4 years from the later of the tax due date or the date the tax was paid. Many practitioners recommend 7 years for uniformity.
Which records should never be thrown away on a schedule?
Anything that establishes what you paid for something you still own. The cost of a property, the improvements made to it, the purchase price of shares and the paperwork behind an inheritance or a gift all determine a position that will only be settled when the asset is sold, which may be decades away. Treat those as permanent records rather than as ordinary ones subject to a retention period.
