Retirees: 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.

Plus, Idaho is sending a second round of tax rebates to eligible residents this year – payments began in September 2022 (the first-round payments went out in March 2022). Rebate payments will be processed through 2022 and into 2023 as residents file the required tax returns.
