Keep bank statements for at least three years after you file your tax return
The IRS generally looks back three years when it audits your tax return. That means you need to keep any bank statement, cancelled check, deposit receipt, or transfer record that supports a number on your return for three years from the date you file. If you filed on April 15, keep statements through April 15 three years later. If you filed an extension and submitted on October 15, the clock starts from October 15.
The three-year window is the standard, but it stretches in specific situations. If you underreported income by more than 25 percent, the IRS can go back six years. If you did not file a return at all, there is no time limit — they can audit any year. If you claim a loss from a worthless security, keep records for seven years. The safest approach is to keep statements for at least six years, since the difference between three and six years costs almost nothing in storage.
Bank statements themselves are not the only records that matter. The IRS wants to see the source of every deposit and the purpose of every withdrawal that relates to income, deductions, or credits you claimed. A statement showing a $5,000 deposit proves money came in, but not where it came from. You also need the invoice, contract, or other document that explains what that deposit was for.
Key Takeaways
- Keep bank statements for at least three years after you file your tax return, because the IRS typically audits returns from that period.
- If you underreported income by more than 25 percent or did not file at all, the IRS can go back six years or longer, so keeping statements for six years protects you.
- Bank statements alone are not enough — you also need receipts, invoices, contracts, or other documents that explain what each deposit or withdrawal was for.
- Digital copies stored in the cloud or on an external drive count as valid records, so you do not need to keep paper statements taking up physical space.
What the IRS actually needs to see during an audit
If the IRS audits you, they will ask for statements that show deposits matching the income you reported. If you claimed $50,000 in self-employment income, they want to see bank deposits that add up to roughly that amount. They will also ask for statements showing withdrawals that match deductions you claimed — business expenses, charitable donations, medical costs, or mortgage interest payments.
For each category of deduction, the IRS wants a paper trail. If you deducted $3,000 in office supplies, you need receipts or invoices showing those purchases, plus bank statements or credit card statements proving you paid for them. If you deducted $5,000 in charitable donations, you need written acknowledgment from each charity plus proof you transferred the money. A bank statement alone showing a $5,000 transfer to a nonprofit is not enough — you need the charity's letter confirming they received it and that it was a donation, not a loan or purchase.
The IRS does not require you to keep original paper statements. Digital copies, screenshots, or PDF downloads from your bank's website are acceptable. Many banks keep statements online for seven to ten years, so you can download and save them yourself. If your bank deletes old statements from their website, download them before that happens.
Different rules for different types of income and deductions
Self-employment income requires the most detailed record-keeping. If you run a business, keep bank statements showing all deposits (income) and withdrawals (expenses) for at least six years. The IRS scrutinizes self-employment returns more closely than W-2 income, so the extra three years of protection is worth the storage space.
Investment income — dividends, capital gains, interest — requires statements from your brokerage or investment account, not just your bank. Keep those for six years. If you sold a stock or mutual fund, the IRS wants to know the purchase price, sale price, and date of sale. Your brokerage statement shows this, but so does your bank statement if you received the proceeds as a deposit. Keep both.
Rental property income and expenses require statements for six years. If you own a rental and deduct mortgage interest, property tax, repairs, or management fees, keep the bank statements showing those payments plus the original invoices or receipts from contractors and vendors.
Charitable donations require bank statements or credit card statements showing the transfer, plus a written acknowledgment from the charity. The IRS is strict about this — a cancelled check or bank transfer alone does not prove the money went to a may have access to charity. Keep both the statement and the charity's letter for six years.
How to organize and store statements so you can find them
The simplest system is to download statements from your bank's website each month and save them in a folder labeled by year and account type. For example: "2024 Checking Statements" or "2024 Savings Statements." If you have multiple accounts, create a separate folder for each. Use your bank's native PDF format — do not convert to other formats, which can cause readability issues if you need to show them to the IRS.
Back up digital copies in at least two places. Save them on your computer, then copy the folder to an external hard drive or cloud storage (Google Drive, Dropbox, OneDrive). If your computer fails or your cloud account is compromised, you still have a copy. Many people also print statements for accounts with significant activity and store them in a filing cabinet, though this is optional if you have reliable digital backups.
Label each file with the account name and month-year: "Chase Checking 01-2024.pdf" or "Wells Fargo Savings 12-2024.pdf." This makes it easy to find a specific statement if the IRS asks for it. Do not rename files to abbreviations or codes — use names that are immediately clear.
Keep supporting documents (invoices, receipts, contracts, charity letters) in the same folder structure. If you deducted office supplies in March 2024, save the receipt in a subfolder labeled "2024 Deductions" or "2024 Business Expenses." When tax time comes or if you are audited, you can pull the entire year's folder and have everything the IRS might ask for.
When you can safely delete old statements
After six years have passed since you filed a return, you can delete the statements from that year. If you filed your 2018 return on April 15, 2019, you can delete 2018 statements after April 15, 2025. Mark your calendar or set a phone reminder so you do not accidentally keep statements longer than necessary.
There are a few exceptions. If you are involved in ongoing litigation, an IRS dispute, or a business audit that spans multiple years, keep all statements related to that case until the matter is resolved. If you claim a loss on a worthless security, keep statements for seven years instead of six. If you own rental property or a business, some accountants recommend keeping statements for ten years, though the IRS standard is six.
Before you delete anything, check with your tax preparer or accountant. They may have specific retention requirements based on your situation. Some people keep statements indefinitely because the storage cost is negligible and the peace of mind is worth it.
What happens if you do not have a statement when the IRS asks for it
If the IRS audits you and you cannot produce a bank statement, you can ask your bank for a copy. Most banks will provide statements going back seven to ten years for a small fee (usually $5 to $25 per statement). Call your bank's customer service line and ask for "statement copies" or "historical statements." Provide the account number and the month and year you need.
If your bank no longer has the statement on file, you can reconstruct the information using your bank's online portal. Many banks allow you to download transaction history in bulk, which shows every deposit and withdrawal for a given period. Export this as a CSV or PDF file and provide it to the IRS. It is not as clean as an official statement, but it shows the same information.
If you cannot produce any record of a transaction, the IRS may disallow the deduction or add the income back to your return. This can result in additional tax owed, plus penalties and interest. This is why keeping statements from the start is much easier than trying to reconstruct them later.
Frequently Asked Questions
Do I need to keep credit card statements too, or just bank statements?
Keep both. Bank statements show money leaving your account, but credit card statements show what you actually purchased. If you deducted $2,000 in office supplies, your bank statement shows a $2,000 payment to Staples, but the credit card statement shows the individual items you bought. The IRS may ask for both to verify the deduction is legitimate.
What if I use a payment app like Venmo or PayPal instead of my bank?
Download and keep statements from those apps the same way you would for a bank. Venmo and PayPal keep transaction history online, usually for several years. Download your transaction history as a PDF or CSV file and save it with your other financial records. These apps are increasingly scrutinized by the IRS, so documentation is especially important.
Can I throw away statements after three years if I am not self-employed?
You can, but six years is safer. The three-year rule is the standard, but the IRS can go back six years if they suspect underreported income. Since storing digital files costs almost nothing, most people keep statements for six years to avoid any risk.
Do I need to keep statements if I did not claim any deductions?
Yes. Even if you took the standard deduction, the IRS may audit your income sources. Bank statements prove where your income came from. Keep them for at least three years, or six years if you want to be safe.
What if my bank goes out of business?
Download all your statements before that happens. If your bank fails, the FDIC insures deposits up to $250,000, but they do not preserve statement history. Once you download statements to your own computer or cloud storage, you own them and can keep them indefinitely, regardless of what happens to the bank.
