Retiring in Florida: tax & Medicare timing checklist

Why Florida is a tax win for retirees

The headline benefit is simple: no state income tax. Compared to a high-tax state like California (up to 13.3%) or New York (up to 10.9%), a retiree drawing $80,000/yr from a 401(k) and Social Security can keep $5,000–$10,000 more per year just by changing address.

• No state income tax on wages, Social Security, pensions, or IRA/401(k) withdrawals.
• No estate tax or inheritance tax — your heirs keep more.
• Homestead exemption — $50,000 off your primary home's assessed value, plus the Save Our Homes 3% annual cap.
• Senior property tax exemptions available in many counties for residents 65+ under income thresholds.

Establishing Florida residency — the checklist

States you leave don't give up tax revenue easily. To win an audit you need a clear paper trail showing Florida is your true domicile, not just a vacation home.

• File a Declaration of Domicile with the county clerk where you live.
• Obtain a Florida driver's license and surrender your old one.
• Register to vote in Florida and actually vote there.
• Register all vehicles and boats in Florida.
• Update your address with the IRS, Social Security, banks, and brokerages.
• Spend more than 183 days per year in Florida and keep records (toll receipts, credit card statements, medical visits).
• If you keep a home in your old state, consider renting it out or making it clearly secondary.

Medicare timing — the 7-month window

The single most expensive mistake new retirees make is missing the Medicare enrolment deadline. The penalties are permanent.

Initial Enrollment Period (IEP)

Begins 3 months before the month you turn 65, includes your birthday month, and ends 3 months after. Sign up at ssa.gov/medicare — you don't need to be collecting Social Security yet.

If you're still working at 65

If you have creditable employer coverage from a company with 20+ employees, you can delay Part B without penalty. You then have an 8-month Special Enrollment Period after the coverage ends. Smaller employers don't qualify — sign up at 65 regardless.

Late enrolment penalties

• Part B: 10% added to your premium for every 12 months you delayed — for life.
• Part D (prescription drugs): 1% per month delayed, added to premiums for life.
• Part A is free if you have 40 quarters of work credits — sign up at 65 either way.

The year-by-year timing checklist

Age 50

• Start catch-up contributions to 401(k) (+$7,500/yr) and IRA (+$1,000/yr).
• Begin Florida scouting trips if relocating.

Age 55

• Rule of 55 — if you separate from your employer at 55+, you can withdraw from that employer's 401(k) penalty-free.
• Start a Roth conversion ladder in your lowest-income years (often the gap between retirement and Social Security/RMDs).

Age 59½

• The 10% early-withdrawal penalty disappears on all IRAs and 401(k)s.
• Roth conversions become especially powerful — pay tax now in a 0% state, lock in tax-free growth.

Age 62

• Earliest Social Security claim — but a permanent 30% reduction.
• Consider whether to claim or bridge with portfolio drawdown (see our Social Security claiming guide).

Age 65 — the big one

• Medicare IEP opens 3 months before your birthday month — enrol on time.
• Compare Original Medicare + Medigap vs Medicare Advantage — Florida has wide plan availability but networks vary by county.
• Sign up for Part D drug coverage.
• If still working with 20+ employee coverage, get a letter of creditable coverage for your file.

Age 67 (FRA for most)

• Full Social Security benefit available — no earnings test, no reduction.
• Stop deferring if you don't have other income to bridge to 70.

Age 70

• Maximum Social Security benefit — 24% more than FRA. Delaying past 70 adds nothing.

Age 73

• Required Minimum Distributions (RMDs) begin on traditional 401(k)s and IRAs. Plan Roth conversions in your 60s to soften the RMD bracket creep.

Hidden Florida costs to budget for

The tax savings are real, but Florida has cost pressures that catch new retirees off guard:

• Homeowners insurance — among the highest in the US. Coastal counties often $4,000–$10,000+/yr; some carriers have pulled out entirely.
• Flood insurance — often required and not included in standard policies.
• HOA and CDD fees in 55+ communities — typically $300–$800/month.
• Sales tax — 6% state + up to 1.5% county.
• Healthcare — Medicare Advantage networks are deep but specialist wait times in popular retiree counties (Lee, Sarasota, The Villages) can be long.
• Hurricane preparedness — shutters, generator, evacuation contingencies.

Pulling it together

Florida works best when you combine three moves: establish residency cleanly before any large taxable event (Roth conversion, big capital gain, pension lump sum), enrol in Medicare on time, and decide on Social Security timing based on health and other income — not on the state tax break alone.
