Before You File S Corporation Form M8

Before You File, Complete Your Federal Return

Before you complete Form M8, complete federal Form 1120S and supporting schedules. You will need to reference them.

Minnesota Tax ID Number

Your Minnesota tax ID is the seven-digit number you’re assigned when you register with the department. Generally, this is the same as your sales and use tax or Minnesota employer’s withholding tax number.

It’s important to include your Minnesota tax ID on your return so that any payments you make are properly credited to your account.

If you don’t have a Minnesota tax ID, apply for one online at or call 651-282-5225 or 1-800-657-3605.
