The standard rule is to keep anything that supports what’s on your tax return for at least three years from the date you filed. That’s the IRS’s basic window to audit most returns. But several situations call for longer retention, so the safer approach is to keep most business records for seven years.

Keep your actual tax returns permanently, or at least indefinitely. They’re easy to store digitally and you may need them to prove prior year income for loans, refinancing, or business transactions years later. For the documents backing up those returns, the three-year rule applies in most cases. It extends to six years if you underreported income by more than 25 percent, and there’s no limit if you never filed.

Bank and credit card statements should be kept for at least three years, though seven is safer. These prove deposits, payments, and the flow of money through your business. If you’re ever questioned about a deduction, the statement showing you actually paid for something is your first line of defense.

Receipts matter because they show what you bought and that it was business-related. A credit card statement proves you spent $127 at Staples, but it doesn’t prove what you purchased. Save receipts digitally since paper fades, gets coffee-stained, and ends up in a shoebox you never open again.

Payroll records need to be kept for at least four years after the tax was due or paid, whichever is later. This includes timesheets, W-4s, records of wages and tips, and documentation of fringe benefits. Keep copies of every 1099 you issue along with the W-9s you collected from contractors for at least four years as well. These documents prove you met your filing obligations.

For equipment, vehicles, and other assets you depreciate, keep purchase records for as long as you own the asset plus seven years after you sell or dispose of it. You need to prove what you paid and when, especially if you claimed depreciation or took a Section 179 deduction.

Good records protect your deductions. If the IRS questions something on your return, you need documentation to support it. Without receipts or statements, you can lose deductions you legitimately earned. With organized records, an audit becomes a paperwork exercise.

Keep everything digital where possible. Scan paper receipts as they come in or use apps that capture them automatically. Store files in a consistent folder structure by year and category. Cloud storage with automatic backup means you won’t lose everything to a hard drive failure or a flooded basement.

When your books are kept properly throughout the year, record retention gets much simpler.
