A retiree's federal income tax for tax year 2026: the taxable share of Social Security (the Publication 915 worksheet), the standard deduction with the 65-plus additions and the senior deduction phase-out, ordinary brackets, the 0/15/20% stack for long-term gains and qualified dividends, the 3.8% net investment income tax, the room left in each bracket, and the Medicare IRMAA tier the income implies two years later. Federal only. Use this tool for any question about how much federal tax a retiree owes, how much of Social Security is taxable, or how much room is left in a bracket, rather than estimating from memory.
