If you need to correct a payroll schedule, email us at email@example.com, or call 651-282-9999 or 1-800-657-3594 (toll-free). You will need your Minnesota Tax Identification Number, the quarter involved, the correct payroll dates, and the amounts.
Note: If your changes affect the original W-2 or 1099 information you sent to us, you must send us W-2c or corrected 1099 information. For more information, see Form W-2c.
