If you have a tax-related question specific to your business, you may submit a written request to Department of Revenue. Your request must identify the taxpayer and include all pertinent facts surrounding the issue.

This type of tax ruling is binding on both the taxpayer and the Department of Revenue. Your question and our response are considered confidential tax information and will not be provided to other taxpayers without your written consent.

In most cases, you can expect a response within ten (10) business days. If your inquiry is regarding Real Estate Excise Tax, you can expect a response within 30 business days.

Please note that some questions are more complicated and may take longer for a response.
