About this guide

Business Filing Calendar is an independent, free guide that puts annual report deadlines, fees and closing steps for the states listed in the footer in one place (more states are added as they are researched), with a link to the official source and a 'last verified' date on each fact.

What this is not

• Not legal or tax advice, and not a law firm, CPA, or registered agent service.
• Not a government site and not affiliated with any state agency, the IRS, or FinCEN.
• Not complete. It covers annual reports and closing steps for LLCs and corporations, plus the basics of NH business taxes. It does not cover every entity type, industry license, or local permit.
• Not guaranteed current. Fees and dates change. Check the official link.

How facts are checked

Facts are read from state agency or legislature pages (see Sources). Items marked 'search excerpt' were seen in a search result excerpt and need to be re-checked on the page. The due date finder computes dates from the state's published rule; where the state publishes a rule instead of a fixed date (for example, '2.5 months after fiscal year end') the tool says it is computed.

Corrections and removal requests

We work to keep every page accurate. If you spot an error, an outdated detail, or information about you that you want corrected or removed, email [email protected] with the page link and what needs fixing.

How we handle it:

• We review every correction or removal request within 7 days.
• If something is wrong, we fix it or remove it.
• When we correct a page, we add a note at the bottom with the date of the correction.
• If we decide no change is needed, we reply and explain why.
