What Records a Small Business Should Keep for Taxes
Updated October 21, 2026
Why records matter more than most people think
Your tax return is only as good as the records behind it. If you cannot show where a number came from, you cannot be sure it is right, and you cannot easily defend it if you are asked. Good records also save money, because you find deductions you would otherwise forget.
The goal is not perfection. It is being able to answer the question: where did this number come from?
Income records
Start with money coming in. Keep these in one place:
- Invoices you sent and records of when they were paid.
- Bank deposit records that match your invoices.
- Any 1099 forms, payment platform reports and sales summaries.
- Cash sales logs, if you take cash.
Match them up regularly. Differences between what clients say they paid and what you recorded are worth catching early.

Expense records
For each expense, you want to be able to show what it was, how much, when, and why it relates to the business. A receipt or an invoice is the best proof. A bank statement alone shows you paid someone, but not what for.
Write a short note on anything unclear. A meal, for example, is easier to explain with a note about who you met and why. Keep personal and business spending apart, which the next guide in this series covers in detail.
Vehicle, home office and other special records
Some deductions need extra backup. If you use a vehicle for work, keep a mileage log with dates, destinations and purposes. If you work from home, keep records that support the space you use and the costs you claim. If you buy equipment, keep the purchase records. The home office guide and the mileage guide go deeper.
Payroll, contractor and tax filing records
If you pay employees or contractors, keep records of what you paid, to whom, and the forms you filed. Keep copies of every tax return you file, with the supporting papers. Save notices from tax agencies and your replies. If you are not sure how long to keep something, ask a qualified professional, because the answer can depend on the type of record.
How to store everything so you can find it
Pick one system and stick with it. A simple folder structure by year, with subfolders for income, expenses, payroll and tax filings, works well. Scan paper receipts on the day you get them and store the scans where they are backed up. Faded thermal receipts are easy to lose, so photos help.
Do a short monthly review rather than a yearly scramble. If you want help keeping the books, see our bookkeeping service, or start your intake to get a free quote for your return.
A year-end records checklist
Before you send anything to a preparer, run through this list so nothing is missing:
- All income forms and a total of any income without a form.
- Twelve months of business bank and card statements.
- Receipts or invoices for every large purchase.
- Your mileage log, if you drive for work.
- Payroll and contractor payment summaries.
- Last year's filed return.
- Any notices you received from a tax agency.
Missing something is common. Tell your preparer what is missing and why, so they can work around it or help you rebuild it from other records. Handing over a complete, labeled folder usually shortens the work and keeps the cost predictable.
FAQ
Do I need paper receipts, or are photos enough?
Clear photos or scans are commonly used. Make sure they are readable and stored somewhere safe and backed up.
How long should I keep my records?
It depends on the type of record and your situation. Ask a qualified professional, and keep records at least as long as you may need them to support a return.
Is a bank statement enough to prove an expense?
Usually not on its own. It shows a payment but not what it was for. Keep the receipt or invoice, and add a note if the purpose is not obvious.
What if I lost a receipt?
Reconstruct what you can from bank records, emails and invoices, and write down what the expense was. Going forward, scan receipts as soon as you get them.
Should I keep records if I use an accountant or preparer?
Yes. Your preparer works from what you give them, and you remain the person who needs to be able to support the return. Keep your own copy of everything you send, organized by year, so you can answer questions quickly and avoid paying for the same document twice.
