Rule one: already in service
If the vehicle was in use at the start of the tax period on 1 July, the return is due by 31 August. That is the deadline most carriers mean when they say "the 2290 deadline", and it covers the whole roster of vehicles that were already running.
Rule two: first used later in the period
If a vehicle is first used part-way through the period, the return for it is due by the last day of the month following the month of first use. A truck first used in November is due by 31 December; one first used in March is due by 30 April.
The tax is prorated for that vehicle across the remaining months of the period, so a vehicle added late does not pay a full year.
| Month first used | Return due by |
|---|---|
| July (or already in service) | 31 August |
| August | 30 September |
| September | 31 October |
| October | 30 November |
| November | 31 December |
| December | 31 January |
| January | 28/29 February |
| February | 31 March |
| March | 30 April |
| April | 31 May |
| May | 30 June |
| June | 31 July |
A weekend or holiday moves the date
When a due date falls on a Saturday, Sunday or legal holiday, the deadline moves to the next business day. This shifts by year, so it is worth checking rather than assuming 31 August.
Filing late
Penalties and interest for late filing and late payment are set by the IRS and accrue from the due date. Filing on time and paying late are treated as separate failures, which is why the way you pay the tax matters: choosing to pay by EFTPS or card rather than authorising a bank debit means the tax is unpaid until you actually do it.
A return that is rejected and then corrected is not automatically late, but the clock does not stop while it sits uncorrected. Rejections close to a deadline are the ones worth acting on the same day.
