Keep tax returns and supporting documents for at least three years from the date you filed

The Internal Revenue Service (IRS) can audit your return up to three years after you file it. That is the baseline: three years is the minimum you should keep everything — your actual return, W-2s, 1099s, receipts, bank statements, and any other papers you used to fill it out. If you throw them away before three years have passed and the IRS comes looking, you will have no proof of what you claimed.

Three years is not a hard important date, though. The IRS can go back further in certain situations, and some records matter more than others. The safest approach is to keep returns and their supporting documents longer than three years — seven years is a common recommendation — and to understand which situations require you to hold on to things even longer.

Key Takeaways

  • Keep tax returns and all supporting documents for at least three years, since the IRS can audit returns filed within that window.
  • If you underreported income by 25 percent or more, the IRS can audit you for six years instead of three.
  • Keep records related to home purchases, investments, and retirement accounts indefinitely, because you may need them when you sell or withdraw.
  • Keep records of business losses and depreciation for seven years, since the IRS scrutinizes these claims more closely.
  • Digital copies stored securely are acceptable, but keep at least one backup in case your computer fails.

When three years is not enough

The three-year rule assumes you reported your income honestly and completely. If you did not — if you left off income, overstated deductions, or made a significant error — the window gets longer. The IRS can go back six years if you underreported your income by 25 percent or more. If you did not file a return at all, there is no time limit; the IRS can pursue you indefinitely.

You should also keep records longer than three years if you claimed a loss on a business or rental property. The IRS audits these claims at higher rates and may want to see documentation going back further. Seven years is a reasonable target for business-related records, depreciation schedules, and anything tied to a loss you carried forward to future years.

Records you should keep forever

Some documents matter long after the three-year window closes because you will need them for future tax returns or major financial decisions. Keep indefinitely any record related to the purchase or improvement of your home — the deed, closing statement, receipts for renovations, and proof of any capital improvements you made. When you sell the house, you will need these to calculate your basis and determine whether you owe tax on the gain.

The same applies to investments. Keep records of what you paid for stocks, bonds, mutual funds, and other securities, along with statements showing reinvested dividends and splits. When you sell, you will need to know your cost basis to figure out your capital gain or loss. Keep records of contributions to retirement accounts — IRAs, 401(k)s, and similar plans — because you may need them to prove you did not over-contribute or to calculate your taxable basis if you made non-deductible contributions.

If you received an inheritance, keep the paperwork showing the date of death and the value of the assets at that time. That value becomes your new basis, and you will need it if you later sell what you inherited. The same goes for any property you received as a gift — keep the documentation of the gift and its value.

What to keep for each type of return

Your federal return is not the only one that matters. Keep state and local tax returns for at least three years as well, since those agencies have their own audit windows. Some states look back longer than the IRS does, so check your state's rules if you live somewhere with a state income tax.

If you file a business return — a Schedule C for self-employment, a partnership return, or a corporate return — keep those records for seven years. Business records are audited more frequently and the IRS often wants to see supporting detail. Keep receipts, invoices, bank statements, and mileage logs if you claim a vehicle deduction. If you claim home office expenses, keep photos and measurements of the space you use.

If you received unemployment benefits, keep the 1099-G statement and any correspondence about the benefits for at least three years. The same applies to any 1099 form you receive — 1099-INT for interest, 1099-DIV for dividends, 1099-NEC for contractor income, and so on. These are the documents the IRS uses to cross-check your return, so you need them to defend yourself if there is a discrepancy.

How to store and organize your records

Paper copies are fine, but digital copies are acceptable to the IRS as long as they are clear and complete. Scan your returns and supporting documents and store them on an external hard drive or in cloud storage. Keep at least two copies — one on your computer or in the cloud, and one backup somewhere else. If your computer crashes or your cloud account is compromised, you still have a copy.

Organize your records by year and type. Create a folder for each tax year and put your return, all 1099s and W-2s, receipts, and any other supporting documents inside. Label them clearly so you can find what you need if the IRS asks. If you have a lot of receipts, group them by category — medical, charitable, business, and so on.

Do not throw away records just because you filed electronically. The fact that you e-filed does not mean you do not need to keep the papers. The IRS has your return, but you need your copies to prove what you claimed if you are audited.

What you can safely discard

After three years have passed, you can throw away some things. Bank statements that do not relate to a deduction or a business can go. Utility bills, grocery receipts, and other everyday spending records can be discarded unless they support a specific deduction you claimed. Paycheck stubs can go once you have verified that your W-2 matches the income shown on your paychecks.

Do not discard anything related to a home, investment, business loss, or retirement account, even after three years. Do not discard anything the IRS specifically asked you to keep. If you received a letter from the IRS about a particular item on your return, keep the records for that item for at least seven years.

What happens if you do not have the records

If the IRS audits you and you cannot find your supporting documents, you are not automatically in trouble — but you are at a disadvantage. The IRS will ask you to reconstruct what you claimed. You can use bank statements, credit card statements, and other documents to show what you spent. You can also use reasonable estimates if you kept contemporaneous notes, though the IRS may not accept them.

If you cannot reconstruct your deductions, the IRS will disallow them. You will owe tax on the income you claimed to have deducted, plus interest and possibly penalties. That is why keeping records is cheaper than trying to recreate them later.

Frequently Asked Questions

Can I throw away my tax return after I file it electronically?

No. Keep a copy of your filed return even though the IRS has one. If you are audited, you will need your copy to show what you claimed and to match it against your supporting documents. The IRS will have your return, but you need yours to defend yourself.

Do I need to keep receipts if I use tax software that stores them?

Keep your own copies as well. Tax software companies can go out of business, change their policies, or delete old data. Store your receipts in your own backup so you are not dependent on a third party to keep them safe.

What if I lost my records and the IRS is auditing me?

Tell the IRS when ready. You can use bank statements, credit card statements, and other documents to reconstruct what you spent. The IRS may accept reasonable estimates if you kept notes at the time. You will be at a disadvantage, but you are not automatically denied your deductions.

How long should I keep records of charitable donations?

Keep them for at least three years. For donations over $250, keep a written acknowledgment from the charity showing the amount and whether you received anything in return. For donations of property, keep the receipt and any appraisal for seven years.

Do I need to keep my W-2 after I file my return?

Keep it for at least three years. Once you have verified that the W-2 matches your paychecks and your return, you can discard the paychecks themselves, but keep the W-2 in case the IRS questions your income.
