Tax year

Everything below updates as you enter data. Nothing here is filed for you — this is the number, and the reasoning behind it, so you are not guessing.

Your profile

Every question here exists because some line of your return cannot be computed without it. You do not have to finish — six answers already produce a real estimate, and the bar below shows how much each remaining answer would sharpen it.

Income & expenses

Every dollar you record here lands on a specific Schedule C line, and every one carries the evidence you have for it. That pairing is the whole point: a total on its own is a number, a total with its evidence is a position you can defend.

Past years

If you kept no records, this is the part that matters most. You are not stuck — but what you can do depends on which deduction it is, and that distinction is worth understanding before you start.

Audit readiness

Not a prediction that you will be examined. This is what your exposure looks like if you are.

CPA handoff

Freeze this year into a package your accountant — or a state examiner — can open in any browser and print. Once created it never changes, even if you keep editing your records.
