The Montana Department of Revenue has a reminder for anyone who lived in Montana for any time in 2020 and worked at their jobs remotely, including those who temporarily relocated due to the COVID-19 pandemic:
You must pay Montana state income tax on any wages received for work performed while in Montana, even if your job is normally based in another state.
Please contact your tax professional for further details.
Learn more about Montana Residency or see The Montana Individual Income Tax Return Instructions for more information.
