Wyoming business tax extension

Wyoming business tax returns
Wyoming business entities pay an Annual Report License Tax with their annual report to the Wyoming Secretary of State (not the Department of Revenue).
Wyoming's rules for each business return, as its own instructions and laws state them:
Annual report and license tax (Secretary of State)
- Return
- Annual Report, with the Annual Report License Tax, filed with the Wyoming Secretary of State
- Due date
- The first day of the entity's anniversary month (the month it formed or qualified in Wyoming) each year; statutory trusts file by January 2
When is the federal business extension due?
Corporations, S corporations, partnerships, multi-member LLCs, estates and trusts extend their federal return with Form 7004, filed by the return's original due date. The extension is automatic: no reason is needed and the IRS doesn't approve it. We e-file it for a flat $9.95. These are the 2027 dates for calendar-year 2026 returns:
| Return | Who files | File the extension by | Extended to |
|---|---|---|---|
| Form 1065 Partnerships & multi-member LLCs, Form 7004 | 6 months | ||
| Form 1120-S S corporations (and LLCs taxed as S corps), Form 7004 | 6 months | ||
| Form 1120 C corporations (and LLCs taxed as C corps), Form 7004 | 6 months | ||
| Form 1041 Estates & trusts, Form 7004 | 5½ months | ||
| Form 990, 990-EZ, 990-PF Tax-exempt organizations & private foundations, Form 8868 | May 15, 2027 is a Saturday | 6 months |
Federal dates follow the IRS rule: a deadline on a weekend or legal holiday moves to the next business day. A fiscal-year business counts from its own year-end; see the fiscal-year deadline guide.
Tax-exempt organizations extend the 990 series with Form 8868, not Form 7004. Each return needs its own extension, so extending a business return does not extend its owners' personal returns.
Does an extension give more time to pay?
No. A federal extension moves the filing deadline only: tax owed is due by the original due date, and the IRS charges interest and the late-payment penalty on anything paid after it. More in does an extension give you more time to pay?
Where are Wyoming's forms and instructions?
On the Wyoming Department of Revenue website, which has the current forms, instructions and online services. The rules on this page are summarized from the sources below. We e-file the federal extension; the Wyoming return and any Wyoming extension request go to the state.
