2026 compliance calendar
Every fixed deadline covered on this site, in date order for calendar-year businesses. Dates that fall on a weekend are shown on the next business day where the agency rolls them forward. Miss one and penalties start. See the penalty guide.
Deadlines that move with your company
- Wyoming annual report and license tax: the first day of your formation anniversary month, every year. See the anniversary guide.
- Nevada Annual List and business license: the last day of your anniversary month.
- California Statement of Information: within the six months ending with your anniversary month, every two years for LLCs, every year for corporations (SOI guide).
- New California entities: first $800 by the 15th day of the 4th month after formation; Statement of Information within 90 days.
- Payroll: Form 941 and California DE 9 each quarter (April 30, July 31, October 31, January 31); W-2s by January 31.
Two rules that apply to almost every row
Extensions move filing, not payment. Federal, California, New York, and Texas extensions all give more time to file the return but not to pay the tax; interest and late-payment penalties run from the original date. Treat Delaware's dates as fixed. When March 1 or June 1 falls on a weekend, pay by the Friday before rather than rely on a next-business-day rule.
Fiscal-year companies should translate each date using the same rule (“15th day of the 4th month after year-end”, and so on). For entity-specific dates, use the calculators or the filing packets, and sign up for deadline reminders on the home page.
