Send 2026 Breakdown → ## How Roth Conversion Taxes Work in 2026 (IRC § 408A & Pro-Rata Rule Form 8606) When you convert pre-tax funds from a Traditional IRA, SEP-IRA, SIMPLE IRA, or pre-tax 401(k) into a Roth IRA under **IRC § 408A**, the converted amount is added directly to your ordinary taxable income on **IRS Form 1040 (and reported on Form 8606)** for the calendar year in which the conversion occurs. In exchange for paying tax at today’s known marginal bracket, all future compounding, qualified withdrawals, and post-death beneficiary distributions (for 10 full years under SECURE 2.0) are **100% exempt from federal and state income tax and exempt from lifetime Required Minimum Distributions (RMDs)**. ## The East Coast Domicile Arbitrage: Why Converting in NYC, NJ, or MA Costs 5% to 14.78% More Than FL, PA, or NH One of the single largest avoidable mistakes among Northeast pre-retirees is executing a large Roth conversion *before* changing state domicile: - **New York City & New York State:** NYS exempts only the first **$20,000** of periodic pension/IRA distributions at age 59½+; large Roth conversions above that threshold face up to **10.9% NYS + 3.876% NYC = 14.776% combined state/city tax**. - **Florida, Pennsylvania & New Hampshire (0% Conversion State Tax):** Florida and New Hampshire levy 0% tax on retirement conversions, and **Pennsylvania (72 P.S. § 7301(d)) exempts 100% of eligible retirement plan distributions and conversions after age 59½**. Waiting until January 1 after establishing bona fide FL, PA, or NH domicile saves **$21,000 to $29,500 in state tax per $200,000 converted**. ## The 2026 Medicare IRMAA Cliff Warning (2-Year MAGI Lookback) Because Roth conversions increase your Modified Adjusted Gross Income (MAGI), crossing a **Medicare Income-Related Monthly Adjustment Amount (IRMAA)** tier by even $1.00 triggers an immediate annual surcharge on Medicare Part B and Part D premiums two years later ($106,000 Single / $212,000 Married Filing Jointly for Tier 1). Always check your conversion size against the IRMAA cliff in the calculator above. ## Interactive 2026 Statutory Model & CPA Verification Checklist Use the interactive simulator embedded above—or open the standalone [**Roth Conversion Tax, 5-Year Ladder & Medicare IRMAA Cliff Guide (2026): Converting in NY/NJ/MA vs. Waiting for FL, PA or NH Relocation Simulator →**](https://eastcorpcapital.com/calculators/roth-conversion-tax-irmaa-ladder/)—to model your exact 2026 dollar figures, compare pre-loaded East Coast presets, and email or export a CSV/PDF worksheet for your CPA or real estate attorney.
