$81,900 difference over 30 yearsFor an identical retiree (age 60, $2M, 60/40, $80K real spend), QuantCalc's Monte Carlo study found a median 30-year state-tax gap of $81,900 between Maryland and Florida — Florida is the cheaper state. That money stays invested, which is why Florida's median terminal balance is higher.

The income-tax difference, year by year
The simplest way to see the gap: on a steady $100,000 annual retirement withdrawal, Maryland collects about $6,500 in state income tax and Florida collects about $0 — a difference of roughly $6,500 every year. County income tax adds 2.25-3.30% on top of the state rate, plus a $5M estate and $1M inheritance tax. No state income tax, no estate tax, a primary FIRE destination.
Over a 30-year retirement, QuantCalc's Monte Carlo simulation (identical portfolio and spending in both states, only the tax code changes) puts the median lifetime state-tax difference at $81,900 — and because the saved tax stays invested and compounds, Florida's median ending balance is the higher of the two.
Beyond income tax
State income tax is only part of the retirement-cost picture. When comparing Maryland and Florida, also weigh:
- Property tax — a tax-free-income state can still have high property tax; factor your home value.
- Sales tax — affects every dollar you spend, not just income.
- Estate / inheritance tax — Maryland: has one; Florida: none. Matters for larger estates.
- Roth conversion cost — converting in the lower-income-tax state of the two cuts the state tax on each converted dollar. See conversion-tax scenarios.
