$120K in Austin vs. $120K in Miami: Why Two 'No Income Tax' Cities Have Wildly Different Total Tax Bills
$120K in Austin vs. $120K in Miami: Why Two 'No Income Tax' Cities Have Wildly Different Total Tax Bills
You got a job offer in Austin. Or maybe you're eyeing Miami. Both states advertise zero income tax like it's the headline feature of a luxury apartment listing. You're thinking: same salary, $0 in state income tax, this is a no-brainer compared to wherever you're coming from.
But here's what that comparison actually looks like when you run the full model: Austin will cost you roughly $5,600 more in annual taxes than Miami — and yet Miami's total housing cost still ends up $4,500 higher per year than Austin's. Two cities with identical income tax bills, radically different financial outcomes.
This is exactly the kind of counterintuitive math that breaks relocation decisions when people only look at the headline number. Let's build the full picture.
The "No Income Tax" Promise: What You're Actually Getting
Texas and Florida are the two most popular relocation destinations in the country, and both sell the same pitch: no state income tax. On a $120K salary, that's a real number. Coming from California (13.3% top marginal rate), New York (10.9% + NYC city tax), or Illinois (4.95% flat), eliminating state income tax saves you anywhere from $5,900 to $15,900 per year in take-home pay.
On a $120K gross salary, federal taxes (single filer, standard deduction) consume roughly $18,500. After federal, your take-home is approximately $101,500. With zero state income tax, that number holds in both Austin and Miami. So far, the comparison is completely flat.
The divergence starts the moment you talk about buying a home — or even renting near one.
The Property Tax Trap in Austin
Texas doesn't have an income tax. It funds its government a different way: through some of the highest property tax rates in the country. The effective rate in Travis County (Austin) runs approximately 2.02% of assessed value annually. That number compounds fast.
A recent Realtor.com investigation traced an Austin family's inheritance of an East Austin property — a home that had been in the family for decades. After the city's dramatic appreciation cycle, the new assessed value triggered a $48,000 annual property tax bill. That's not a special assessment. That's the base rate applied to what the market decided the property was worth.
Even at the median, the math is aggressive. Austin's median home price in 2024 sits around $525,000. Apply the 2.02% effective rate:
$525,000 × 2.02% = $10,605/year in property tax
That's $884 per month leaving your account before you've paid for utilities, groceries, or the mortgage itself. Texas does offer a homestead exemption (~$100,000 off assessed value for primary residences), which reduces this to roughly $8,575/year — but only if you file promptly and occupy the home as your primary residence. Inherited or investment properties often don't qualify immediately.
For context: that $8,575 in property tax alone is more than the state income tax bill you'd pay in Illinois on the same salary.
Florida's Property Tax Situation: Lower Rates, But Watch the Trajectory
Florida's effective property tax rate runs around 0.86% — less than half of Texas's. On a Miami-area median home (approximately $620,000), that's:
$620,000 × 0.86% = $5,332/year in property tax
And Florida has the Save Our Homes cap — a constitutional provision that limits annual assessment increases to 3% or inflation (whichever is lower) for homesteaded properties. That's a meaningful protection Texas doesn't offer.
Governor DeSantis has floated going further, proposing the elimination of homestead property taxes entirely. The backstory, reported by Realtor.com: Florida's property tax revenue has exploded from $31 billion to $55 billion in five years — a 77% increase driven almost entirely by appreciation. DeSantis calls this a "gusher" and argues eliminating homestead property taxes is now financially "doable."
Whether that proposal survives politically is another question. But directionally, Florida's property tax trajectory is downward by policy intent, while Texas's is upward by structural design (no income tax to lean on).
This is the kind of tax policy analysis worth building into your 5-year model, not just your first-year budget. You can run that timeline at Vontari without building it from scratch.
The Insurance Wildcard That Completely Changes Miami's Math
Here's where Miami's lower property tax rate stops feeling like an advantage.
South Florida sits in a Category 5 hurricane corridor. The state's insurance market has spent three years shedding carriers, and the ones remaining — including the state-backed Citizens Insurance — have raised rates dramatically. A standard homeowner's policy in Miami-Dade on a $620,000 home now runs $5,000 to $8,000 per year, depending on construction type, elevation certificate, and flood zone designation.
Austin's insurance profile is very different. Texas has its own storm risks (hail, tornadoes), but the average homeowner's premium in the Austin metro runs approximately $2,400 to $3,000 per year.
That $2,600 to $5,000 insurance gap nearly erases Miami's property tax advantage.
The Full Model: $120K in Austin vs. $120K in Miami
Here's the annual housing cost breakdown for a $120K earner buying at the local median, with 20% down at a 6.5% fixed rate:
| Cost Category | Austin (TX) | Miami (FL) |
|---|---|---|
| Home Price (Median) | $525,000 | $620,000 |
| Down Payment (20%) | $105,000 | $124,000 |
| Loan Amount | $420,000 | $496,000 |
| Annual Mortgage P&I | $31,860 | $37,620 |
| Annual Property Tax (homestead) | $8,575 | $5,330 |
| Annual Homeowner's Insurance | $2,700 | $6,500 (mid-range) |
| Total Annual Housing Cost | $43,135 | $49,450 |
| As % of $120K Gross | 35.9% | 41.2% |
State income tax: $0 in both cities.
Total annual property + sales tax burden:
| Tax Category | Austin (TX) | Miami (FL) |
|---|---|---|
| State Income Tax | $0 | $0 |
| Property Tax (homestead) | $8,575 | $5,330 |
| Sales Tax Rate | 8.25% | 7.0% |
| Est. Sales Tax on $30K Spending | $2,475 | $2,100 |
| Total Non-Federal Tax Burden | $11,050 | $7,430 |
| Austin Premium | +$3,620/year | — |
Austin costs more in taxes. Miami costs more in total housing. The "no income tax" promise is real in both cities — but it's not the number that determines your financial outcome.
This is exactly the kind of multi-variable comparison that Vontari was built to model — because the table above changes materially based on your purchase price, loan terms, and whether you're buying vs. renting.
What the Coastal Homeownership Data Confirms
Realtor.com's recent analysis of homeownership costs found that in several coastal metros, housing alone consumes nearly 100% of typical wages — a statistic that sounds absurd until you do the arithmetic above on Miami at $620K. At the median Miami income (not $120K, but closer to $65K-70K), the housing cost table above represents more than 70% of gross pay before a single dollar goes to food, transportation, or healthcare.
This is why the "no income tax" comparison between Florida and Texas can be misleading for people at lower income levels. The tax savings on $70K from no state income tax is roughly $2,100 in a median-rate state. The insurance cost difference between Austin and Miami can be three times that amount.
For similar analysis between other Sunbelt markets, we modeled the Raleigh vs. Tampa comparison in depth — including how NC's property tax reforms and Florida's no-income-tax edge interact at a $95K salary.
The Renter's Version of This Comparison
If you're not buying — which is increasingly common in both markets — the property tax comparison shifts to a landlord-pass-through model. In Austin, the same 2.02% property tax rate that hammers owners gets embedded in rent pricing. A landlord with a $525K property is passing $8,575+ in annual taxes into your monthly rent whether you see it on a line item or not.
Miami's rental market has its own dysfunction. As Realtor.com reported, New York City's rent-stabilized market data shows what happens when rent control intersects with rising operating costs: owners absorb the pain in the short run, then exit the market or reduce maintenance in the long run. Miami has no rent stabilization, so landlord cost increases flow through to renters faster — but the transparency is at least cleaner.
For renters, the practical upshot is: Austin rents embed high property taxes; Miami rents embed high insurance and land costs. The per-square-foot spread narrows significantly when you're renting rather than owning.
The Bottom Line for a $120K Earner Choosing Between These Two Cities
Neither city is universally cheaper. Here's the honest matrix:
Austin wins if:
- You're renting, not buying (avoids the property tax exposure directly)
- You're buying under $400K (property tax burden is more manageable, insurance is lower)
- You don't need coastal proximity and can live further from downtown
- Texas property tax reform becomes a political priority (possible but not guaranteed)
Miami wins if:
- You're buying a homesteaded property and plan to stay 10+ years (Save Our Homes cap compounds in your favor)
- DeSantis's property tax elimination proposal moves forward
- You qualify for Florida's homestead exemption and can document residency quickly
- Your income is above $150K+ (the insurance cost becomes a smaller percentage of your overall picture)
The number most people miss: The gap between Austin and Miami isn't in income taxes — it's in the combination of property tax rates, insurance premiums, and median home prices. Those three numbers interact differently at every price point, every income level, and every purchase timeline.
Before you sign a lease or make an offer, run your actual numbers — your salary, your target home price, your insurance quotes, your expected tenure. The spreadsheet that actually answers this question isn't the one with the headline "no income tax." It's the one that adds up everything else.
Vontari models the full picture — income tax savings, property tax burden, insurance cost ranges, and total housing cost as a percentage of your take-home pay — so you know whether the city you're moving to is actually a financial upgrade for your specific situation.
