Sales, Use, and Withholding - Ask a Question
For account specific questions, you will need to include the business's identification number and address as well as your relationship to the business. Additionally, if responding to a notice we sent to you, include the Letter ID printed at the top of page one.
Online responses to questions cannot contain any sensitive information and may take up to five business days to be available. Account-specific responses will instead be mailed to the legal address on your account.
To retrieve our response to your question, you will need the Service Request number that was sent to you via email after submitting your question, as well as the email address and phone number that you used when you initially asked the question.
