How to categorize 1099 expenses from a bank statement
Download your business bank or card statement as CSV or Excel and choose it above. Each payment goes into an expense line of Schedule C (Form 1040), and each line is added up. You check every row, move any that landed on the wrong line, mark personal spending, and download the totals and rows as CSV for your return or tax preparer. Deposits are left out: take your gross receipts from your own records.
What are the Schedule C categories?
Schedule C (Form 1040) 2025 lists business expenses in Part II, lines 8 to 27b, totalled on line 28. The names below are copied from the form; goods bought for resale go in Part III, line 36.

Which 1099 expenses are deductible?
The IRS instructions speak of ordinary and necessary expenses of your business. For example, line 17 takes accountants' and attorneys' fees, including business tax preparation; line 18 office supplies and postage; line 25 utilities, but not the base rate of the first phone line into your home; line 9 actual car costs or the standard mileage rate, 70 cents per mile for 2025. For meals, the total shown on line 24b is what you spent: the deductible amount is a percentage, in most cases 50%, and entertainment is not included.
Keywords cannot know your business: a fuel payment may be partly personal, and some costs are depreciated rather than deducted. The tool does not split business and personal use and does not cover business use of your home on line 30. Check every figure with the IRS instructions for Schedule C or a tax preparer.
