How we verify deadlines

Last updated: October 7, 2026 · General information, not legal advice

A reminder with the wrong date is worse than no reminder. This page says where the dates in the tracker come from, how you can check each one yourself in one click, and what the tracker does not know.

The rule we follow

A state goes into the tracker only when its rule is written on the state's own website, in its statutes or on one of its official forms, and can be turned into a date without guessing. Other websites, search results included, sometimes help us find the official page. They are never the evidence.

What you see next to each date

Under every date in the tracker there is a line like this:

Official source · checked Oct 7, 2026

Official source opens the state's own page, statute or form where the rule is written.
Checked is the day we last read the rule on that page ourselves. It is not the day the state last changed it.
For a few states the line says "Official site · not re-checked by us yet". That means the state's site would not load for us the last time we tried, so the date still rests on our earlier research. We show that instead of a date we could not stand behind. Those are the rows to confirm first.

The same source and date appear in the deadlines-by-state table and in the calendar file you can download from the tracker.

When the source leaves room, we show the earlier date

Some rules can be read two ways by a day or two. In those cases the tracker shows the date that is never late. Three examples: Alaska's statute says the report is due "before January 2", so the tracker shows January 1. Connecticut's says "before April first", so it shows March 31. Vermont gives three months after the fiscal year ends; for a year that ends on September 30 the tracker shows December 30, not December 31.

What the tracker does not know

Whether you have filed. It shows where the next date falls on the calendar. It cannot see your filings.
Your LLC's first year. Many states ask for the first report in the year after formation. The tracker has one date rule per state and does not model first-year exceptions, so a brand-new LLC may see a date that does not apply to it yet.
Anything outside the one filing we track. Fees, late penalties, filing windows, business licenses and taxes paid to another agency (California's $800 annual LLC tax is one) are not tracked unless the note under the date says so.
Entities that are not LLCs. The rules are the ones for limited liability companies. In several states corporations and partnerships have different dates.
States we left out on purpose. Some states set the date on the exact anniversary day, which the tracker does not ask for; one changes its rule in January 2027; for a few we could not read the rule on the state's own pages. The list, with the sources, is at the end of the deadlines-by-state guide.

How often we re-read the sources

We read a state's source before adding it, and again when we learn that its rule has changed. There is no automatic monitoring: a state can change a rule between two of our checks. That is why every date carries the day we last read it, and why you should confirm on the official page before you rely on a date. The link is there so that takes one click.

Found a date that looks wrong?

Email aifucina@gmail.com with the state and, if you have it, the official page. We will read the state's page again and correct the tracker if the date is wrong.
