Notes

This estimator uses 2026 tax brackets and standard deductions. It does not account for state taxes, AMT, itemized deductions, or credits. Qualified dividends and LTCG share favorable rates but may be subject to the 3.8% Net Investment Income Tax (NIIT) above certain thresholds. Medicare Part B/D IRMAA surcharges apply based on MAGI from 2 years prior.
