How to categorize transactions for taxes
If you're self-employed or running a business, your transaction categories need to map to IRS expense types on Schedule C:
- Advertising — marketing, design, ads
- Car & Truck — gas, parking, Uber if for business (keep mileage log)
- Meals — 50% deductible for business meals with clients
- Office Expenses — supplies, software subscriptions, SaaS tools
- Rent — office rent (not home rent unless home office deduction)
- Utilities — partial deduction if home office
- Professional Fees — accountant, lawyer, consultant
- Insurance — business insurance premiums
Tip: Export your categorized transactions as CSV from mybankstatementanalysis, then filter by business categories in Excel. This gives you a clean expense report for your accountant — or for filling out Schedule C yourself.
