UCR deadlines: when registration opens, closes and is enforced

The annual calendar

For registration year 2026:

The pattern repeats: registration for any year opens on 1 October of the year before, is due by 31 December, and is enforceable from 1 January.

What happens if you miss it

Nothing closes. There is no window after which you can no longer register, and registering late is normal. What changes is exposure: from the enforcement date an unregistered carrier can be cited at a roadside inspection or during an audit, and several states assess penalties per occurrence.

Registering late stops the exposure going forward. It does not undo a citation already issued, which is the whole argument for doing it in the autumn rather than in February.

A common false comfort: "I paid last year, so I am on the system." UCR does not carry over. Each registration year is bought separately, and last year's receipt is evidence about last year only.

Does it renew automatically?

Not with us. We do not store your card and we do not file on your behalf without being asked, because an automatic renewal at last year's fleet size is worse than no renewal — it files a number that may now be wrong, and you would have no reason to look.

Some services do offer automatic renewal. If you use one, check which registration year each charge covers and what fleet size it was filed at.

Does my fee change year to year?

Yes, in two ways. The published government fees are reset for each registration year, and your own bracket can move if your fleet has. Our form starts from your current FMCSA record every time rather than reusing last year's answer — see how to count your vehicles.
