Compliance calendar

This page is a map of the kinds of dates a US company usually meets. It is a reminder guide, not a substitute for a CPA or tax attorney, and not a complete IRS or secretary-of-state database.

After you form, the dashboard builds a calendar from your filing date, state, and entity. Open it from Tax & compliance once you are signed in.

Federal income tax

• Partnership returns (Form 1065) are typically due March 15 for calendar-year filers.
• Corporate returns, including Form 5472 with a pro-forma 1120, are typically due April 15.
• Extensions exist. We date them as plan-ahead, not as a promise that the state will wait.

States we publish dates for

• Wyoming — annual report on the first day of the anniversary month of formation.
• Delaware LLC — $300 annual tax due June 1. Delaware C-Corp — franchise tax and annual report due March 1. The franchise amount is not computed here.
• Florida — annual report window January 1–May 1. We date May 1 as due.
• Texas — franchise tax and public information report due May 15 for calendar-year filers, with a first-report rule that depends on the formation date.
• New Mexico LLCs — no SOS annual report.

Sales tax and payroll

Sales-tax due days are estimated until nexus is confirmed. Payroll 941 / 940 reminders appear only as estimated chips until staff confirm you have employees. Delaware has no state sales tax.

What we do not put on a countdown

FinCEN’s August 2026 final rule removed BOI reporting for companies formed in the United States. The dashboard says no action required. Do not expect a BOI deadline for a domestic company.
