#5 Least Tax Friendly State to Retire: Montana
Not that you’re very eager to retire to Montana without a good reason, but the state certainly doesn’t want to provide you with one.
While the state does not impose a general sales tax, it more than makes up for that in other areas. The state taxes most forms of retirement income and its top tax rate hits taxable income of more than $16,400. The state’s taxes aimed to tourists also hit residents, with accommodations, campgrounds, and rental vehicles (great for retirees out exploring) all taxed at a higher rate.
