August first use: what to know
An August first-use puts you in an odd spot: your deadline lands on September 30, a month after the famous August 31 date — yet many August buyers panic-file as if they were late. You aren't. You owe 11 of 12 months of tax, and your clock is your own.
The rule behind the date: Form 2290 is always due the last day of the month following the month of first highway use, rolling to the next business day on weekends and holidays. “First use” means the public highway — not the purchase date, not the registration date.
Dates shown are computed for the current tax period and adjust for weekends; IRS holiday shifts may apply. General information, not tax advice.
