This is not entirely true. First, social security: at most you pay tax on 25% of your social security benefits; and if your total income is under $60,000 (married) or $50,000 (single), they don't tax it at all. Secondly, for his other retirement income, there's an exemption of $15,000 or $24,000 (single/married), so depending on his income mix, the state income tax bite is much less than 6%. So we're not at the top of the retirement state lists to be sure, but it's not as bad as people make it out to be.
