When you e-file Form 2290 with ExpressTruckTax, the IRS will apply a digital watermark to your Schedule 1 once approved. This electronic stamped Schedule 1 is your official proof of HVUT payment, and all DMV locations are required to accept this document. If a state or local DMV will not accept your IRS 2290 Schedule 1 you will need to contact the IRS Excise Hotline at 1-866-699-4096 opt. 4 and provide the IRS with a brief description of the issue and the contact information of your local DMV. The IRS will be able to assist and ensure that your DMV accepts your electronic stamped Schedule 1.
