Note: Form 2290 deadlines for the 2026–2027 tax period are shifted when the standard deadline falls on a Saturday, Sunday, or legal holiday. In those cases, the filing and HVUT payment deadline moves to the next business day. (Taxpayers affected by certain disasters may qualify for IRS relief that postpones applicable filing and payment deadlines.)
Important: An extension to file Form 2290 does not automatically give you additional time to pay the tax. The IRS treats the filing and payment extensions separately.
