State of Montana does not tax my unemployment but federal does. Do I need to file amended tax return to receive benefit?

There is no need to file an amended return (Form 1040-X) to figure the amount of unemployment compensation to exclude. The IRS will refigure your taxes using the excluded unemployment compensation amount and adjust your account accordingly. The IRS will send any refund amount directly to you.
