The Department of Revenue works hard to ensure we process everyone’s return as securely and quickly as possible.
Unfortunately, it can take up to 90 days to issue your refund and we may need to ask you to verify your return.
We encourage all Montanans to file early and electronically. This is the easiest and most secure way to file and get your refund as quickly as possible.
Remember, we are here to help. Please contact us if you need additional assistance.
