The decision turns on two rates — yours now and yours at withdrawal — and for anyone who might move, the largest thing moving them is which state you retire in. This models both states rather than assuming you stay put.
What your state actually takes from a 401(k) withdrawal, a pension, and Social Security — in dollars, not a yes/no list.
2026 limits, employer match, the 60-63 super catch-up, and whether the Roth catch-up mandate applies to you.
Long-term index-fund growth after expense-ratio drag — and what your state takes from the gains at withdrawal.
A required minimum distribution is ordinary income, taxed at your top bracket and often pushing you into the next one. Here is the federal tax on RMDs from $20,000 to $75,000 at different income levels, why the default 10% withholding usually leaves a bill, how to avoid an underpayment penalty, and the three side effects that make the real rate higher than the bracket.
The required minimum distribution on every common balance at every age from 73 to 95, worked from the IRS table, plus what happens to the account over twenty years of withdrawals at 0%, 5% and 7% returns. The short version: the share you must take rises every year, and at good returns the dollar amount keeps rising with it.
What moving actually saves, on your own income mix rather than a headline rate — and how to establish domicile so the state you left cannot follow you.
Which account to draw first, priced. The three cliffs a withdrawal can cross without warning, the conversion window almost nobody uses, and why the order is the last big decision you can still change.
