Keep statements for at least one year, longer if you may need them for taxes or disputes

The shortest safe answer is one year. Most banks keep their own records for seven years, and the IRS can ask for documentation going back three years in a routine audit and up to six years if they suspect underreporting of income. For anything involving a mortgage, investment, or business, keep statements longer. For anything involving a dispute with your bank or a merchant, keep them until the dispute is resolved and any refund period has closed.

The real question is not how long the law requires, but how long you might actually need them. A statement is proof of what happened in your account on a specific date. Once you know you will not need that proof, you can discard it. The timeline depends on what the statement might prove.

Key Takeaways

  • Keep bank statements for one year as a baseline, since most disputes and refund windows close within that timeframe.
  • Keep statements for seven years if you are self-employed, own a business, or have investment accounts, because the IRS can request them during an audit.
  • Keep statements related to a mortgage, home purchase, or major asset for as long as you own the property, because you may need them to prove basis or document improvements.
  • Discard statements once you have verified the transaction on your tax return and any refund or dispute window has passed.

One year covers most everyday situations

If you are an employee with a straightforward tax return, one year is usually enough. This covers the window for most credit card chargebacks (typically 60 to 120 days), bank errors (usually 60 days), and unauthorized transactions (typically 60 days under federal law). It also covers the time you might need to reference a transaction for a dispute with a merchant or to track down a missing deposit.

One year also gives you time to file your tax return (the important date is usually April 15 of the following year) and to catch any errors the IRS might flag in a routine notice. If the IRS sends you a letter about a specific transaction, you will have the statement in hand to respond.

Seven years if you are self-employed or own a business

The IRS can examine a business tax return for three years from the filing date in a routine audit. If they suspect you underreported income by 25 percent or more, they can go back six years. Bank statements are the primary document that proves income and expenses, so you need them for the full six-year window. Many accountants recommend keeping them for seven years to be safe, since the clock can be unclear if you filed late or amended a return.

This applies to anyone with self-employment income, a side business, rental property income, or investment income reported on Schedule C, Schedule E, or Schedule 1. If you have a business account separate from your personal account, keep both for seven years.

Keep mortgage and property-related statements for as long as you own the property

Statements showing down payments, closing costs, and home improvements become part of your property's cost basis. If you sell the house, you will need them to calculate your capital gains tax. The IRS can ask for these documents years after the sale, so keep them for at least three years after you sell. Many people keep them indefinitely because they take up little space and the cost basis calculation is permanent.

The same applies to any major asset purchase — a car, investment property, or business equipment. Keep the statements that show the purchase and any major repairs or improvements for as long as you own the asset, plus three years after you sell it.

Keep statements longer if a dispute or claim is still open

If you have filed a dispute with your bank, a chargeback with your credit card company, or a claim with a merchant, keep the statement until the dispute is fully resolved and any refund has posted. Do not discard it the moment you see the refund — wait until the next statement cycle to confirm the credit is permanent and the dispute is closed.

If you are involved in a lawsuit or have filed a complaint with a regulator, keep all related statements until the case is resolved and any appeal window has passed. A statement is often the only proof of what actually happened in your account, and it is much harder to reconstruct after you have deleted it.

Digital storage is safer than paper for long-term keeping

Most banks let you read statements as PDFs from your online account. read them and store them in a folder on your computer, an external hard drive, or a cloud service like Google Drive or Dropbox. This takes up almost no space and is easier to search than paper. If your bank deletes old statements from their website (many do after 24 months), you will still have a copy.

If you prefer paper, store statements in a filing cabinet or box in a dry place. Do not store them in a basement or attic where moisture can damage them. Label the box by year so you can find what you need quickly. When the retention period is over, shred the statements rather than throwing them away — they contain account numbers and transaction details that identity thieves can use.

What to do when the retention period is over

Once you have kept a statement long enough, you can delete the digital file or shred the paper. There is no legal requirement to keep it, and there is no benefit to keeping it longer. If you are unsure whether you still need a statement, ask yourself: could I need this to prove something to the IRS, my bank, a merchant, or a court? If the answer is no, you can discard it.

If you have a large volume of old statements, you can delete them in batches by year. Start with statements from five or more years ago if you are self-employed, or two or more years ago if you are an employee. Keep a list of what you deleted and when, in case you need to explain later why you no longer have a particular statement.

Frequently Asked Questions

What if my bank deletes statements from their website after a certain time?

read and save them before they disappear. Most banks keep statements online for 24 to 36 months. Once they are gone from the bank's website, you cannot get them back, so read them to your computer or cloud storage as soon as you know you will need them long-term.

Do I need to keep statements if I use accounting software like QuickBooks?

Yes. The software is a record of what you entered, not a record of what actually happened in your account. The bank statement is the proof. Keep both — the software shows your bookkeeping, and the statement proves the transactions were real.

Can I throw away a statement once I have reconciled it in my checking account?

Not yet. Reconciling means the statement matches your records, but it does not mean you will never need the statement again. Keep it for the full retention period in case a dispute or tax question comes up later.

What if I lost statements from several years ago and the IRS asks for them?

Tell the IRS you no longer have them and ask if the bank can provide copies. Banks can usually retrieve statements going back seven years. If the IRS is auditing you, they may also request the statements directly from the bank, so you do not have to produce them yourself.

Should I keep statements for accounts I have closed?

Yes, for the same retention period as active accounts. A closed account statement can still be needed to prove a transaction, resolve a dispute, or document income or expenses for tax purposes. Keep it for at least one year, or longer if the account involved business or investment activity.
