The agency’s timing guidance
These are status-availability estimates. First-time Montana filers receive a paper check; missing or mismatched information may delay processing.
Use the correct official service
Open the official state agency page below and follow its refund-status link. Keep the filed state return available for that service. Enter sensitive tax information only on the official agency website.
Keep federal and state processing separate
Your federal and state returns can be accepted and reviewed at different times. An IRS approval does not establish a state payment date. Follow the state tracker and any state notice for the next step.

Questions you might have
When will my Montana refund arrive?
Status may be available around 2 weeks after e-filing or 18 weeks after paper filing. These agency estimates or tracker instructions are not a guaranteed payment date.
Where do I check a Montana refund?
Use the official Montana agency page linked here. Enter personal details only in the official service; this site never asks for them.
Does my federal refund date predict my state refund?
No. Federal and state returns are processed by separate agencies. Their acceptance dates, reviews and payment dates can differ.
What if my state return needs review?
These are status-availability estimates. First-time Montana filers receive a paper check; missing or mismatched information may delay processing.
