Every Calculator Here Asks You for the Same Number
Total business expenses. It is the input that moves all four answers, and it is the one almost nobody can produce accurately, because the receipts behind it are in a truck, a drawer, and three different card statements.
TaxTidy produces it for you. Photograph a receipt and it reads the vendor, the amount and the date in about three seconds, then files the expense on its Schedule C line with the image kept alongside it. Run any of these calculators again in six months and you will be typing in a real figure instead of an estimate.
Your Audit Readiness Score shows what is still open behind that figure — expenses with no receipt, charges nobody categorized — while there is still time to fix it.
TaxTidy provides expense organization tools based on the most current US tax law available to it. TaxTidy is not a CPA, Enrolled Agent, or licensed tax professional. All categorizations, deductions, and tax calculations are estimates. Please verify all data for accuracy and consult a certified tax professional before filing.
