Dates current as of mid-2026. Filing frequencies vary (some businesses file sales tax quarterly or annually), and your CPA may have entity-specific dates — treat this as the calendar skeleton and confirm the specifics for your business. Preparing for the spring deadlines? Start with the year-end tax prep checklist.
Deadlines are only stressful when the books behind them aren't ready. When you outsource bookkeeping with InsightTrack, the filings on this page stop being events — sales tax numbers are ready on the 20th, 1099s go out in January, and your CPA gets reconciled books well before March. We track the calendar so you don't have to. Schedule a free consultation.
