2.4k views | Last modified 3/23/2023 6:56:14 AM EST | Added by TaxBandits Team

The Montana Department of Revenue requires the filing of W2 Forms even if there is no state tax withholding. TaxBandits supports the filing of Form W-2 with both the SSA and the State of Montana.

However, we do not support filing Reconciliation “Form MW-3” with the state, and the employer is responsible for filing the reconciliation form before the deadline.

What to be filed

Form W-2 Wage and Tax Statements
Form MW-3 Montana Annual W-2 1099 Withholding Tax Reconciliation.

Due Date

The filing due date for Form W2 with Montana is January 31.

Penalty

A penalty of $50 or $5 for each W2 not filed on time with the state of Montana.

Mailing Address

If you withheld taxes, mail your Form W2 along with MW-3 and W-3 to the following address:

Montana Department of Revenue,
PO Box 5835,
Helena, MT 59604-5835.
