Moving States to Save on 401(k) RMDs? A $2.1 Million Case Study Reveals the Hidden Federal Cost

Quick Read Moving from California to Nevada eliminates the 9.3% state income tax on RMDs, saving six figures over 20 years on a $2.1 million IRA.

Nevada residency doesn't fix federal exposure: IRMAA surcharges kick in above $109,000 MAGI, and up to 85% of Social Security stays federally taxable. A Qualified Charitable Distribution of up to $111,000 in 2026 can satisfy the entire first RMD and keep it out of AGI completely. Two retirees, same $1 million, same 4% rule, buy one finished with $1.

4 million, the other hit $0 in 12 years. Our free reader guide explains the flaw that separated them, and the income-first method built to avoid it. A recent post on r/personalfinance describes exactly this move: a father who rolled a large 401(k) into a traditional IRA at 72, then relocated from California to Nevada for what the poster called "a 9.

3% instant savings once RMD hits." The specifics fit a common profile: a $2.1 million balance, a first required minimum distribution one year away, and a California tax bill that grows every year the account does.

The math on why the U-Haul is worth it, and the federal trap the move does not solve, is more interesting than the headline. Prostock-studio / Shutterstock.com The RMD Number That Starts the Cascade Under the IRS Uniform Lifetime Table, the divisor at age 73 is 26.

5. On a $2.1 million balance, that produces a first-year required distribution of roughly $79,245.

Every dollar counts as ordinary income, and the number climbs annually as the divisor shrinks. By the late 70s, an untouched portfolio compounding at market rates will push mandatory withdrawals well past $100,000. California treats that income as wages.

A single filer pulling $79,245 in RMDs runs through the state's graduated brackets and lands roughly $3,800 in state tax the first year, with the marginal dollar taxed at 9.3%. California's top marginal rate reaches 13.

3%, and the Tax Foundation ranks the state 49th out of 50 on individual income tax competitiveness. Nevada ranks 7th and imposes 0% personal income tax. The 4% Rule is Broken, Built On A World That No Longer Exists Every retiree knows about the 4% rule, but it frames retirement as a slow liquidation and still causes retirees with seven-figure accounts to agonize over a dinner out.

There's a different way to run the math that makes more sense today. Build an income floor — dividends, interest, and Social Security that cover your essential bills every month — and you never have to sell shares into a down market just to pay them. Our free reader guide, The 4% Rule Is Broken, walks through it in about 15 minutes.

A retiree drawing between $80,000 and $140,000 annually from age 73 to 93 keeps six figures more in California under a Nevada domicile, without changing a single investment decision. The cost-of-living side amplifies it: BEA data pegs California's regional price parity at 110.72 versus Nevada's 99.

979, a spread of roughly 10.7 points on housing, services, and goods. The same $79,245 RMD simply buys more in Reno than in Roseville.

High-net-worth Californians are already making this move. Auto-finance billionaire Don Hankey traded his Malibu estate for a $21 million penthouse in Las Vegas, and luxury real estate agents reported California buyers dominating the Nevada market as the state's proposed billionaire tax advanced. The Federal Trap That Follows You Across the State Line The move does not fix the federal side.

IRMAA, the Medicare premium surcharge, is federal and uses a two-year income lookback. For 2026, the first surcharge tier kicks in at modified adjusted gross income above $109,000 for single filers or $218,000 joint. The standard Part B premium is $202.

90 per month; crossing the first threshold adds roughly $1,148 per person annually, and higher tiers stack quickly. A single retiree combining a $79,000 RMD with $40,000 of Social Security lands squarely in surcharge territory. Nevada residency does nothing to blunt that.

Neither does it prevent up to 85% of Social Security becoming taxable at the federal level. The California Franchise Tax Board also does not accept the move on faith. The FTB completed 520 residency audits in 2023, more than double 2019, and applies a "close connection" test covering driver's license, club memberships, family location, and even the origination points of phone calls.

Keeping a Malibu house while claiming a Henderson address is a documented audit trigger. What Actually Needs to Happen Before the First RMD Establish clean Nevada domicile well before the RMD year. Register to vote, transfer the driver's license, retitle vehicles, change primary physician, and, ideally, sell or lease out the California primary residence.
