Submit Contractor Affidavit by Mail

Note: Before the Minnesota Department of Revenue certifies a Contractor Affidavit, we must have all Withholding Tax returns and payments on file for the entire contract period. Log in to our e-Services system to file returns and make payments. Allow up to 10 business days for us to process payments before resubmitting a Contractor Affidavit.

To file a Contractor Affidavit by mail, complete Form IC134, Contractor Affidavit.

You’ll also need:

• Your Minnesota Tax ID Number (if employees worked on the project) or Social Security Number
• The beginning and ending dates you worked on the project
• Project number
• Total contract amount and amount still due
• Project location
• Project owner
• Project owner's complete address
• The name and address of the company hiring you (if the project owner did not hire you)
• Copies of certified contractor affidavits from each subcontractor

If you are a single-member corporation, you are considered an employee of your own business. For more information, see Withholding Fact Sheet 6 – Corporate Officers.
