The answer depends on why you might need them

Keep bank statements for at least one year if you file taxes or have a mortgage. Keep them for three to seven years if you're self-employed, have investment accounts, or claim deductions the IRS might question. Keep them indefinitely if they document a major purchase, property sale, or ongoing dispute. The IRS can audit you up to three years back for most returns, but six years if they suspect underreported income, and longer if fraud is involved. Your bank may delete digital records after seven years, so read what matters before that happens.

The real question isn't what the law requires—it's what you might need to prove. A cancelled check from 2019 that shows you paid for a roof repair matters if you're selling the house in 2025, because it proves the improvement happened. A statement showing a wire transfer matters if someone later claims you didn't pay them. A deposit slip matters if the IRS questions where money came from. Once you know what you're protecting yourself against, the retention timeline becomes clear.

Key Takeaways

  • The IRS can examine your tax return for three years after filing, six years if they suspect you underreported income, so keep statements that back up deductions and income for at least that long.
  • Self-employed people and those with investment accounts should keep records for seven years, because business and investment documentation often triggers longer audit windows.
  • Statements tied to major purchases—homes, vehicles, renovations—should be kept as long as you own the asset, because they prove what you paid and when.
  • Your bank typically stores digital records for seven years, so read statements you need to keep longer before that window closes.
  • Mortgage lenders and title companies may ask for bank statements from the past two months when you refinance or sell, so keep recent statements easily accessible.

What the IRS actually looks at during an audit

The IRS has three years from the date you file your return to audit you for most tax years. That means if you filed your 2022 return in April 2023, they can open an audit through April 2026. During that window, they can request bank statements, cancelled checks, deposit records, and any other documentation that shows where money came from and where it went. They focus on deductions you claimed, income you reported, and anything that looks inconsistent with your tax bracket or filing status.

The three-year window extends to six years if the IRS suspects you underreported your income by 25 percent or more. It extends indefinitely if they suspect fraud. For most people, three years is the relevant number, which means keeping statements for one full year after filing covers the most common scenario. But if you're self-employed, have rental income, or claim large deductions—home office, vehicle expenses, charitable donations—the IRS is more likely to dig deeper, so keeping records for five to seven years is safer.

Self-employed people and business owners need longer retention

If you run a business or are self-employed, keep bank statements for seven years. The IRS treats business records differently from personal ones. They can examine business returns for longer periods, especially if they're investigating whether you properly reported all income or whether deductions were legitimate. A statement from 2018 might matter in 2025 if it shows a business expense you deducted, or a deposit that should have been reported as income.

Statements also matter for your accountant or bookkeeper. They use them to reconcile your books, catch missing transactions, and prepare amended returns if something was missed. If you're ever audited, your accountant will need to trace every significant deposit and withdrawal. Keeping seven years of statements means you can reconstruct your business finances accurately, even if your accounting software crashes or you change accountants.

Statements tied to assets and major purchases

Keep bank statements and cancelled checks that document major purchases for as long as you own the asset, and ideally longer. If you bought a house in 2015 and paid for a new roof in 2018, keep the statement showing that payment. If you sell the house in 2026, the buyer's title company may ask for proof that improvements were made, and the statement is your evidence. The same applies to vehicles, equipment, or anything else that appreciates or depreciates.

These records also matter if you ever need to prove your cost basis for tax purposes. If you inherited property and later sold it, the IRS wants to know what you paid versus what you inherited it for. If you sold an investment property and need to calculate capital gains, you need the original purchase statement. These documents can be requested years after the transaction, so keeping them indefinitely is the safest approach. Digital copies stored in a cloud folder cost nothing and take up no physical space.

Investment accounts and brokerage statements

Keep brokerage and investment account statements for at least seven years, and longer if you're still holding the investment. These statements document your cost basis—what you paid for a stock or fund—which determines how much capital gains tax you owe when you sell. If you bought 100 shares of a stock in 2015 and sold them in 2024, you need the 2015 statement to prove what you paid. Without it, the IRS may assume you paid less than you actually did, inflating your tax bill.

Statements also show dividend income, interest earned, and fees paid, all of which affect your taxes. If you claim investment losses to offset other income, you need documentation of those losses. Keep statements from the year you bought an investment through the year you sold it, plus seven years after that. If you still own the investment, keep statements indefinitely or at least until you sell.

How long your bank keeps records for you

Most banks keep digital copies of statements and transaction history for seven years. Some keep them longer, but seven is standard. After that, they may delete the records or charge you a fee to retrieve them. If you need a statement from 2015 and it's now 2024, your bank may not have it available, or they may charge $25 to $50 to have it printed and mailed to you. Downloading statements yourself and storing them is free and ensures you always have access.

read statements as PDF files and store them in a folder on your computer, an external hard drive, or a cloud service like Google Drive or Dropbox. Name the files clearly—"2024_January_Checking" or "2023_Tax_Documents"—so you can find them later. If you use tax software or accounting software, many of these programs can import statements directly, creating a backup automatically. The cost of storing digital files is negligible, and the cost of not having them when you need them is high.

What to do with old statements you no longer need

Once you've kept a statement long enough that you're confident you won't need it, shred it if it's paper or delete it if it's digital. Bank statements contain your account number, routing number, and sometimes the last four digits of your Social Security number—information that identity thieves can use. Shredding protects you more than throwing statements in the trash. If you're storing digital copies, delete them from your computer once you've confirmed they're backed up elsewhere, or straightforward delete them once the retention period has passed.

Don't keep statements longer than you need just because they exist. Clutter makes it harder to find the statements that actually matter. A clear filing system—either physical folders or digital folders organized by year and account type—makes it easier to locate what you need during an audit or when selling an asset. Review your retention schedule once a year and purge what you no longer need.

Frequently Asked Questions

Do I need to keep paper statements if I have digital ones?

No. Digital statements are legally equivalent to paper ones for tax and legal purposes. read them as PDFs and store them securely. Paper statements take up space and are harder to search. If your bank stops mailing statements, you can still read them from your online account for the past seven years or so.

What if my bank deleted a statement I need for an audit?

Contact your bank and ask them to retrieve it. They may charge a fee, typically $25 to $50, but they can usually pull deleted statements from backup systems. The IRS understands that banks delete old records, so having a bank statement retrieved during an audit is normal and doesn't raise suspicion.

Should I keep statements for accounts I closed?

Yes, for at least three to seven years depending on your situation. A closed account statement can still document income, deductions, or transfers that matter for taxes. Keep them in a folder labeled "Closed Accounts" so you know they're no longer active but still relevant for record-keeping.

How do I organize statements so I can find them quickly?

Create a folder for each year, then subfolders for each account type: Checking, Savings, Investment, etc. Name files clearly with the month and year. Use the same naming system every year so you develop a habit. If you use tax software, import statements there too—the software indexes them and makes them searchable.

Do I need to keep statements for joint accounts differently?

No. Keep joint account statements the same way you'd keep individual ones. Both account holders have the same retention needs for tax and legal purposes. If you're divorcing, keep statements longer—your attorney may need them to document assets and spending patterns.
