Surprise Retirement Taxes in 2026: 3 New Tax Traps Every Retiree Must Plan for Now

If you’re planning for retirement in 2026, you may be heading toward unexpected tax increases — even if you believe you’ve done everything right.

Most retirees are familiar with basic retirement tax issues, such as required minimum distributions (RMDs) from traditional IRAs and 401(k)s. But new federal tax policy changes, combined with shifting state tax rules, could quietly raise your tax bill in ways many retirees aren’t prepared for.
