Investopedia and MSN both report that some states provide multiple tax breaks to retirees. However, the two sources differ slightly in their specific details. Investopedia mentions that several states do not tax Social Security benefits, 401(k)s, IRAs, and pensions, while MSN specifically notes nine states have no state taxes on any kind of income.
Investopedia highlights some states as giving retirees multiple tax breaks, but does not specify which ones. In contrast, MSN provides a list of these nine states that do not tax retirement income: Alaska, Florida, Nevada, New Hampshire, North Dakota, South Dakota, Texas, Washington, and Wyoming [1][2].
The sources agree on the existence of such states, with Investopedia stating some states give multiple tax breaks to retirees. However, they disagree on which specific states offer these benefits or have no state taxes on retirement income.
