Can I write this off? WriteOff tells you, and tells you why.
Snap a receipt or type what you bought. You see:
• Yes, partly, or no, in plain words
• Your write-off: how much of what you paid counts, with the math shown
• Why, in a sentence or two
• Where it goes on your tax form (the Schedule C line, for Schedule C filers)
• What records to keep
• The IRS source behind the answer, one tap away
ONE QUICK QUESTION WHEN IT MATTERS
If the answer depends on a fact, like who was at the meal or how much you use the laptop for work, WriteOff asks one question at a time and remembers your answer for next time. It never guesses a fact that changes your write-off.
RULES DECIDE, AI READS
Answers come from a rules engine built on IRS publications, notices, and form instructions for each tax year, including the 2026 mileage rates and depreciation limits. AI only reads your receipt and words the explanation. It can't change the answer or the amount.
HONEST WHEN IT'S NOT A WRITE-OFF
If something isn't deductible, WriteOff says so plainly and shows what would change the answer. It will never help invent a business purpose.
EVERYTHING IN ONE PLACE
Every check is saved with its receipt, your answers, and its sources. Search your history, see this year's total, and export a CSV or PDF for your accountant.
COULD THIS COUNT MORE?
With Pro, WriteOff checks each expense for legitimate ways it could count more: a method or election your preparer can make, or a fact you were never asked. Each idea shows the potential deduction, what it takes, and the IRS source, and you can add it to your tax pack. It only shows ideas that fit your answers, and never suggests calling personal spending business.
TAXES TAB
See your next deadline, what's left to fix, and send everything to your tax preparer with one link.
BANK STATEMENTS
Upload a statement from your bank or card as a PDF, CSV, OFX or QFX file. WriteOff lists the purchases, leaves out payments and transfers, marks the charges that look like business, and asks one quick question about each of the rest. CSV, OFX and QFX files, and PDFs with text, are read on our server without AI. Your first statement is free.
MIXED RECEIPTS
When a receipt has both business and personal items, WriteOff lets you split them.
BUILT FOR SMALL BUSINESS OWNERS
Works for sole proprietors, LLCs, S corps and partnerships. Keep more than one business separate.
