The Part Missouri Does Not Do For You
Whatever Missouri takes, it takes on your net profit — and net profit is just 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 Missouri wants its own return alongside the federal one, 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.
Frequently Asked Questions
Can I deduct federal taxes on my Missouri return?
Yes, partially. Missouri allows a deduction for federal income tax paid, capped at $5,000 (single) or $10,000 (married filing jointly).
Does Missouri require an annual LLC report?
No. Missouri does not require an annual report for LLCs, and there is no annual fee. This makes it one of the cheapest states for ongoing LLC maintenance.
When are Missouri estimated taxes due?
Quarterly on April 15, June 15, September 15, and January 15. Required if you expect to owe just $100 or more — one of the lowest thresholds in the country.
