Retirees Will Quietly Choose Arizona Over Florida and the Reason Will Be Health Care
The tax difference between Arizona and Florida barely moves the needle, but one Medicare decision made at 65 locks in costs that compound for thirty years and cannot be undone later.

For decades, Florida has been the default answer when people imagine where they will retire, but more couples now run the numbers on Arizona instead, and the deciding factor is usually health care. The tax gap between the two states gets the attention, but what determines the move is the cost of staying insured from age 65 to 95. The comparison covers the cost of the move. It also covers how that turns into a portfolio target, and the Medicare detail that makes the choice largely permanent.
What a Comfortable Retirement Costs in Each State
A useful starting point is the average American household, which spent $78,535 a year in the latest Consumer Expenditure Survey. That figure already covers housing, food, utilities, vehicles, home maintenance, gifts, and out-of-pocket health spending. It leaves out income taxes. Regional price levels move it from there, as Arizona’s price index sits at 100.677, close to the national benchmark of 100, while Florida’s is 103.414. Adjusted for those indexes, the same lifestyle runs about $79,000 a year in Arizona and about $81,200 in Florida.
Medicare is part of that budget in both states. The standard Part B premium is $202.90 a month per person, or about $4,900 a year for a couple. The Part B deductible is $283, and one hospital stay brings a Part A deductible of $1,736. Those costs keep rising. National health care spending reached $3,861.3 billion annually, up about 6.8% from a year earlier. Total consumer spending rose about 6.1% over the same period.
How Arizona’s Tax Bill Shifts the Portfolio Target
A married couple both drawing Social Security averages about $4,152 a month, or $49,824 a year. Arizona exempts Social Security from state tax but charges a flat 2.5% on most other income, which includes IRA withdrawals. Florida has no state income tax. After Social Security, the Arizona couple needs about $30,000 a year from savings, and that figure already includes the state tax. The Florida couple needs about $31,400. Federal tax on withdrawals this small is usually low for couples over 65, but it belongs in the reserves bucket.
At a 4% withdrawal rate, the targets come to about $750,000 for Arizona and $785,000 for Florida. A 3.5% rate, which fits a 30-year horizon better, raises them to about $857,000 and $897,000. Taking age changes the result more than the choice of state does. Delaying to 70 can raise the payout. Couples who do so can collect up to $10,362 a month combined at the maximum, and each year of delay reduces the gap the portfolio has to cover. Benefits also adjust each year, and the 2027 cost-of-living increase is tracking toward 3.3%.
Medigap Pricing Is Where Florida Loses Ground
The biggest long-term cost difference is how Medigap premiums change with age. Florida uses attained-age rating, where premiums rise as you get older. Arizona also uses attained-age rating. The difference is that Florida’s starting premiums are already higher, and the state’s regulatory environment has historically produced larger increases over time. A Florida household pays that extra premium every year, it compounds with age-based increases, and the Florida budget above does not include it.
Medigap timing is also rigid. Guaranteed issue applies only during the six-month window that opens at 65 with Part B enrollment. After that, insurance companies can reject applicants based on health. A Florida retiree with a Medicare Advantage plan may later want a supplement. Getting one may require passing medical underwriting, and a diagnosis at 72 can make that impossible. Premiums are priced by where the policyholder lives, so the state chosen at 65 effectively sets the supplement costs for the next three decades.
Early retirees face a second hurdle. The enhanced ACA premium subsidies expired, so a pre-Medicare bridge in either state depends on keeping taxable income low. Funding early years from cash, taxable brokerage accounts, or a Treasury ladder keeps marketplace premiums in check. Arizona’s state tax doesn’t affect Medicare’s income surcharges. Those surcharges start above $218,000 of joint income (IRMAA is one of several premium traps we mapped in a free Medicare guide).
What It Takes to Make the Arizona Move Work
A couple with average Social Security and an average American lifestyle needs about $750,000 to $860,000 invested to retire in Arizona. That assumes withdrawals of 3.5% to 4% and a balanced mix of index funds and bond ladders. The number drops quickly if you delay Social Security. For Florida, the target runs higher even before pricing the higher Medigap premium.
Arizona’s lower price level more than covers its 2.5% tax. Medigap is the deciding factor, though, because underwriting rules make the state chosen at 65 very hard to change later. Choosing the state before the first Medicare enrollment and buying the supplement during the guaranteed-issue window set the premium a household carries until 95.
