Callers from Canada or Mexico can use 859-320-3581, which is not toll-free. Have your EIN, return, reporting period, vehicle information, and payment details ready.
For broader business tax matters, the IRS lists 800-829-4933. For an in-person appointment at a Taxpayer Assistance Center, call 844-545-5640.
IRS representatives can help with account issues, but your filing provider is usually the better first contact for rejected submissions, software errors, or a missing downloadable Schedule 1.
