Montana is extending its tax filing deadline to May 17 to match the new federal deadline.
Gov. Greg Gianforte says the change will give Montanans extra time to file without worrying about interest or penalties. The new federal stimulus plan allows filers to exclude the first $10,200 of unemployment benefits from federal taxes if they made less than $150,000. Those who have already filed will not have to amend their returns. The Department of Revenue says it could take up to 90 days to process tax refunds due to security measures being taken against identity theft and fraud.
