Records the IRS expects from a sole proprietor
A freelancer in the US is usually a sole proprietor. IRS Publication 334 says a sole proprietor owns an unincorporated business by themselves, and that Schedule C (Form 1040) is used to figure net profit or loss from the business. Net profit depends on knowing your income and your expenses, which is where your records come in.
The IRS publication on recordkeeping, Publication 583, says everyone in business must keep records. It says the law generally does not require a specific type of records and that you can use any system that clearly shows your income and expenses.
This is general information, not tax, legal or financial advice. What you can deduct depends on your situation. Read the linked IRS publications and ask a qualified tax professional if unsure.
Supporting documents and what a statement can show
Publication 583 describes your books as a summary of transactions, usually in journals and ledgers, backed by supporting documents such as sales slips, paid bills, invoices, receipts, deposit slips and canceled checks.
It also says that if you do not have a canceled check, you may be able to prove payment with certain financial account statements prepared by financial institutions. But it adds that proof of payment of an amount, by itself, does not establish that you are entitled to a tax deduction. You also need documents, such as invoices, that show the cost was incurred.
So a bank statement is one piece of the records. It shows a payment happened; the invoice or receipt shows what it was for.
Turning statements into an expense sheet
Convert each month's statement PDF to a spreadsheet so every transaction is a row, then add columns for Category and Business use (Yes/No). The categories can follow whatever headings your tax professional or software uses. A synthetic example:
Date Description Amount Category Business?
02/02/2026 Example Software Sub -29.00 Software Yes
02/05/2026 Client A invoice 1041 1,500.00 Income Yes
02/11/2026 Example Coffee Shop -6.40 Personal No
02/14/2026 Example Office Supply -42.15 Office supplies YesFilter the Business column to Yes, then sum by category. Mixed-use payments, such as a phone bill, are the ones to look at manually, and the personal rows are easy to exclude when they have their own flag.
Our checking of the IRS publications did not turn up a statement that lets us tell you which categories to use for a given deduction, so we do not list "deductible" categories here. Use the IRS guidance for that.
Separating business and personal money
Publication 583 says one of the first things to do when you start a business is open a business checking account, and to keep it separate from your personal checking account. It also recommends reconciling the account monthly, and noting the source of each deposit.
A separate account makes the statement itself the starting point of your ledger, because fewer rows need sorting out. If you must use a personal account, a Business? column like the one above does part of the same job.
Keep original statements and receipts alongside the spreadsheet; the spreadsheet is an index to them, not a replacement, and we are not saying it meets any IRS requirement. PDFtoRow can convert statement PDFs into Excel or CSV to start the sheet.
