State-by-State Small Business Tax Guide — 2026
State taxes can make or break your bottom line. Each guide covers your state's income tax rates, self-employment rules, estimated payment requirements, filing deadlines, and specific deductions — everything a freelancer or small business owner needs to stay compliant and keep more of what they earn.
One Set of Receipts, Two Sets of Deadlines
Whichever state you land on, the tax gets charged on net profit — what you earned minus what you can prove you spent. Your state and the IRS want that proof on different schedules, from the same shoebox.
TaxTidy keeps one clean record that answers both. 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. Nothing gets entered twice, and nothing waits on you remembering a purchase from eight months ago.
Your Audit Readiness Score shows how solid that record is before anyone — federal or state — asks to see 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.
