$90k in Austin vs Miami: Same Taxes, Different Life

City War • 3 min read • Updated for tax year 2026 • Estimates, not tax advice

Quick answer: Texas and Florida both charge no state income tax, so a $90,000 salary nets about $72,145 a year (~$6,012 a month) in both Austin and Miami. The differences come from rent, homeowner insurance and car costs.

Identical tax math

Item	Amount
Gross salary	$90,000
Federal income tax	$10,970
State income tax	$0 (TX and FL)
FICA	$6,885
Annual take-home	$72,145
Monthly	~$6,012

Where the cities differ

Monthly	Austin	Miami
Take-home	~$6,012	~$6,012
1-bedroom rent (typical)	$1,400-$1,900	$2,200-$3,000
Car insurance	~$140	~$250+
Homeowner insurance (if buying)	~$200	$500-$800+
Total tax burden	No income tax, higher property tax	No income tax, high sales tax and insurance

Miami's advantage is no state income tax plus no winter. Its disadvantage is that insurance — auto and property — is among the most expensive in the country. Austin's advantage is relatively lower rent for a major tech market; its disadvantage is property taxes that often exceed 1.8%.

The rule for comparing them

Budget on take-home minus rent minus transport. At the midpoints above, Austin leaves roughly $3,900 a month after rent, Miami about $3,100 — before either city's car and insurance realities. If you plan to own a home in Florida, model insurance carefully: it can add $300-$500 a month versus Texas on a comparable house.

Cost details people forget

Florida sales tax plus county surtax runs 7-8%; Texas is 8.25% in most cities.
Both states require a car in most neighbourhoods, so add $400-$600 monthly for payment, fuel, insurance and maintenance.
Miami's hurricane season can mean special assessments and higher deductibles.
Austin's summer utilities run high; Miami's run year-round.

FAQ

Insurance is the hidden Florida line item

Florida homeowners insurance has become one of the largest cost differences between the two states. On a comparable $400,000 home, a Florida policy can run $4,500-$8,000 a year versus roughly $2,400-$3,600 in Texas. Add windstorm deductibles, and the monthly gap can exceed $300 — a bigger number than most people expect when comparing "no income tax" states.

Weather, utilities and quality of life

Austin summers push electricity bills to $180-$280 a month; Miami runs air conditioning year-round, so its bills stay high in every month. Both cities have no state income tax, so the decision usually comes down to housing stock, job market and whether you want seasons or ocean.

How to run your own numbers

At $90,000, each extra $1,000 of wages costs about $220 in federal tax (22% marginal bracket) plus roughly $76 in FICA — you keep about $704 of it. Enter any salary in the calculator to see your own split; the donut shows exactly which slice grows with each raise.

Federal effective rate at this income

On $90,000 single, federal tax is $10,970 — an effective federal rate of 12.2%. That is well below the 22% marginal rate, because lower slices of income are taxed at 10% and 12%. The rest of the gap between gross and take-home is FICA plus any state tax.
