Common follow-up questions
When do RMDs start in 2026?
RMDs start at age 75 for anyone born in 1960 or later (under SECURE 2.0). For those born 1951–1959, RMDs began at age 73. The penalty for missing an RMD is 25% of the amount that should have been withdrawn — reducible to 10% if corrected within two years.
Are Roth conversions worth it before RMDs?
Often yes — particularly the years between retirement and RMD age, when income is typically lowest and you can fill up the 12% and 22% brackets at controlled cost. The break-even point is usually 8–15 years depending on your future bracket and growth assumption. Run a side-by-side comparison before deciding.
How much of my Social Security gets taxed?
It depends on combined income. Below $32,000 MFJ ($25,000 single), 0% is taxable. Between $32,000 and $44,000, up to 50% is taxable. Above $44,000, up to 85% is taxable. The thresholds aren't indexed to inflation, so more retirees cross them every year.
Do retirees pay state income tax?
It depends on the state. Nine states have no state income tax at all (FL, TX, TN, NV, SD, WY, AK, NH, WA). Most states exempt some or all of Social Security. A handful (CA, NY, OR, NJ) tax 401(k) and IRA withdrawals fully as ordinary income — significant if you live there in retirement.
When this doesn't apply
These figures assume federal-only taxation, traditional 401(k)/IRA balances, and a married-filing-jointly status. State taxes, single filers, large taxable brokerage accounts, large pensions, or active business income materially change the math.
