Retirees: Most Tax-Friendly (Go to the Kiplinger Tax Map for Retirees)

At first blush, the Gem State might not look like a tax-friendly state. Idaho's current top income tax rate of 6% kicks in at a fairly low amount, making the tax hit feel more like that of a coastal state.

But, if you dig a little deeper, you'll see some good news on taxes. Starting in 2023, a new, lower flat income tax rate applies. And sales taxes aren't too bad, either. Plus, since groceries are taxable, the state offers a tax credit of $100 per person to offset the sales tax on them ($120 if you're over 65). The state's median property tax rate is well below average, too. And to top things off, Idaho doesn't have an estate tax or inheritance tax.
