Tax Reference

2026 numbers, in one place.

These are the exact federal figures planbend's calculators and retirement projections use — not separately researched, so they can't drift from what your plan actually models. Rules change most years; when the IRS or CMS publish new numbers, this page updates alongside the app.

Federal income tax brackets

Taxable income up to each ceiling is taxed at that bracket's rate. See Marginal Tax Rate.

IRMAA — Medicare surcharge tiers

Based on MAGI from two years prior. Surcharge is Part B + Part D combined, per person, per year, on top of the standard premium. See IRMAA or the IRMAA calculator.

Required minimum distribution (RMD) divisors

RMDs start at age 73. Divide your prior year-end balance by the divisor for your age to get the required withdrawal. See RMD or the RMD calculator.
