Montana is one of only five states with no sales tax. How does this affect my taxes?
Montana has no state sales tax (one of five states with no sales tax), which benefits big spenders. However, the state compensates with progressive income tax rates up to 6.75%. Many people moving to Montana for the 'no sales tax' benefit are surprised to find their income tax burden is actually higher than in some sales-tax states. A $75,000 earner pays an effective rate around 5.5%-6% (approximately $4,125-$4,500 annually), while the same earner in a flat-tax state like Pennsylvania would pay $2,300 (3.07% flat, though PA may have local EIT).
Montana exempts all retirement income from state tax. Does this apply to everyone?
Yes. Montana does not impose state income tax on Social Security benefits or retirement distributions (pensions, 401(k) withdrawals, IRA distributions) for all residents, regardless of age. Combined with the lack of sales tax and the progressive brackets with lower starting rates (1%), Montana is attractive for retirees, especially those who spend heavily on goods and services.
