The Part New Hampshire Does Not Do For You
New Hampshire skipping the income tax does not get you out of federal self-employment tax, and that lands on your net profit — what you earned minus what you can prove you spent. The proving is on you, and it is where most of the money leaks out.
TaxTidy is where the proof lives. 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. Nothing gets typed in twice, and nothing depends on you remembering a purchase from eight months ago.
Because New Hampshire wants its filings on its own schedule, the same organized record does double duty — one set of receipts, sorted once, ready for whichever deadline comes first. Your Audit Readiness Score shows you how solid that record is before anyone else asks.
