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).
I'm moving to Montana from Washington. How much will my taxes increase?
Washington has no state income tax, so moving to Montana means you'll pay income tax (effective rates around 5.5%-6% for most earners). A $75,000 earner will pay approximately $4,125-$4,500 annually in Montana state income tax, while the same earner in Washington pays $0. However, Montana's lack of sales tax means you won't pay sales tax on purchases, which can offset income tax differences for big spenders. Factor in both income and spending patterns when evaluating the move.
