$120K Salary in New York City vs. Phoenix vs. Denver: Taxes, Housing Costs, and the $45K Annual Purchasing Power Gap
You made the call. After 2025 — when New York City shed another 12,000 residents according to Realtor.com, reversing the post-pandemic recovery — you're on the list. Your $120K salary sounds solid, but between the $3,900/month apartment, the NY state income tax bracket, and the NYC city surtax that quietly bites every paycheck, you're watching that number shrink faster than it should. Phoenix and Denver are on your shortlist. The Sunbelt pitch is clean: better weather, cheaper rent, lower taxes. But "no city income tax" is not the same as a free lunch. Let's build the actual spreadsheet.
Who's Leaving NYC — and Why the Numbers Matter for Middle-Income Earners
The Realtor.com population analysis is notable for one reason most headlines missed: this isn't just wealthy New Yorkers decamping to Florida. The 2025 decline spans renters, middle-income households, and families priced out of decent school districts. If you're earning $120K in the five boroughs, you're not rich in New York. You're working-class adjacent — paying top-tier cost of living while watching your savings move slowly, if at all.
That context matters because the financial case for leaving NYC looks very different at $120K than it does at $300K. The tax savings are proportionally smaller. The housing delta matters more. And the transition costs hit harder. So let's model all of it — before you sign a lease in Scottsdale or put in an offer near Capitol Hill.
The Tax Math: NYC vs. Phoenix vs. Denver
This is the first place the move pays off, and it pays off meaningfully. Here's what state and local income taxes actually cost a single filer earning $120K in each city:
New York City stacks two separate income taxes on top of federal:
- NY State income tax runs a graduated bracket from 4% at the low end to 6.85% on income above $80,650. On $120K, total NY state tax comes to approximately $7,437
- NYC city income tax adds a separate local layer, with rates topping at 3.876%, adding approximately $4,526
- Combined state + city hit: $11,963/year — over $1,000/month before you've paid rent
Arizona (Phoenix): Arizona moved to a flat 2.5% income tax in 2023. On $120K: $3,000/year. Phoenix imposes no additional city income tax.
Colorado (Denver): Colorado runs a flat 4.4% state income tax: $5,280/year. Denver charges a small occupational privilege tax of approximately $500/year, bringing the total to roughly $5,780/year. For a fuller breakdown of how Colorado's flat tax compares to a zero-income-tax Texas city, the Denver vs. Dallas income and property tax analysis models that pair in detail.
| Location | State Income Tax | City Income Tax | Total State/Local Tax |
|---|---|---|---|
| New York City | $7,437 | $4,526 | $11,963 |
| Phoenix, AZ | $3,000 | $0 | $3,000 |
| Denver, CO | $5,280 | ~$500 | $5,780 |
The immediate swing: Phoenix saves you $8,963/year in state and local income taxes compared to NYC. Denver saves you $6,183/year. Meaningful — but taxes alone don't determine where the money actually goes.
This is the kind of full-layer tax modeling Vontari runs automatically, because most people only check whether a state has income tax, not what their effective bill actually is on their specific income.
The Housing Equation: Where Sunbelt Math Gets Complicated
Taxes get the headlines. Housing is where the real story lives — and where the Sunbelt pitch gets its first stress test.
NYC rent (2025): A livable one-bedroom in Manhattan or inner Brooklyn runs $3,700–$4,200/month. Working median: ~$3,900/month, or $46,800/year.
Phoenix rent (2025): Phoenix absorbed a massive migration wave post-2020, and rents rose sharply — but have since stabilized. A comparable one-bedroom runs $1,450–$1,650/month. Working median: ~$1,550/month, or $18,600/year.
Denver rent (2025): Denver's post-pandemic rent plateau has settled into a $1,750–$2,000/month range for a comparable one-bedroom. Working median: ~$1,875/month, or $22,500/year.
| Location | Monthly Rent (1BR) | Annual Rent | Annual Savings vs. NYC |
|---|---|---|---|
| New York City | $3,900 | $46,800 | — |
| Phoenix, AZ | $1,550 | $18,600 | +$28,200 |
| Denver, CO | $1,875 | $22,500 | +$24,300 |
Stack the tax and rent savings together and the Sunbelt case looks overwhelming. It mostly is — but there's a structural shift underway in Phoenix that buyers specifically need to understand before committing.
The Phoenix Luxury Surge: A Warning for Anyone Planning to Buy
A Realtor.com market analysis found that Phoenix has overtaken Denver as the Mountain West's luxury real estate leader, with a $1.5 million entry point for the luxury tier — a threshold Denver hasn't yet crossed. That's not just a premium-market footnote. Luxury construction activity competes for the same labor, materials, and land as mid-tier development. When capital follows luxury returns, entry-level and mid-range inventory tightens.
Phoenix's median home price has climbed to approximately $415,000–$430,000 in 2025. Denver's median sits closer to $565,000–$580,000. So Phoenix still wins on median purchase price — but the gap has compressed significantly from five years ago, and Phoenix buyers at the $400K–$550K range are now competing with institutional purchasers and cash-flush coastal relocators.
Property tax comparison on a purchase scenario:
- Phoenix: Effective property tax rate of 0.6–0.8%. On a $430,000 home: $2,580–$3,440/year
- Denver: Effective rate of ~0.5–0.6%. On a $575,000 home: $2,875–$3,450/year
Phoenix's lower rate is real, but the math on a financed purchase at 6.5%+ mortgage rates compresses the advantage. A $430K Phoenix home at 20% down carries a monthly payment around $2,450–$2,600 — not dramatically lower than a comparable Denver payment when you account for the $150K price difference.

The Hidden Cost Pattern: What the Tax-Free Retirement Playbook Gets Wrong
A Realtor.com investigation into states that don't tax retirement income identified a consistent trap: states that advertise zero income taxes — think Florida, Tennessee, Nevada — often carry housing costs and property tax bills that quietly absorb most or all of the savings. The same dynamic is now playing out for working-age Sunbelt migrants.
Phoenix, for all its income tax efficiency, is no longer the cheap-housing story it was in 2018. The same migration pressure that made the tax math appealing also drove prices up. A relocator who moves for the $9K income tax savings but pays $80K more for a home than they would have four years ago hasn't won — they've traded a monthly cost for a capital cost, with the same underlying burden spread across 30 years of mortgage payments.
The lesson from retirement-state analysis applies directly here: income tax savings are only durable if housing costs don't absorb them. At current Phoenix entry prices, renters capture the full advantage. Buyers need to model the purchase carefully.
The Full Picture: BLS Purchasing Power on $120K
BLS Regional Price Parities (RPPs) measure what a dollar actually buys across metro areas, adjusting for goods, services, and housing separately. The 2023 BLS data shows:
- NYC metro RPP: ~122.7 (22.7% more expensive than the national average)
- Denver metro RPP: ~106.7
- Phoenix metro RPP: ~101.8
After taxes and rent, the leftover income has to cover groceries, healthcare, transportation, and everything else. In NYC, that remaining dollar buys roughly 18% less than the same dollar in Phoenix on non-housing goods and services.
Here's the full comparison — effective purchasing power after state/local taxes and rent:
| New York City | Phoenix | Denver | |
|---|---|---|---|
| Gross salary | $120,000 | $120,000 | $120,000 |
| State + city income tax | ($11,963) | ($3,000) | ($5,780) |
| Annual rent (1BR) | ($46,800) | ($18,600) | ($22,500) |
| After tax + rent | $61,237 | $98,400 | $91,720 |
| BLS non-housing cost adjustment | -18% vs. Phoenix | baseline | -4% vs. Phoenix |
| Adjusted purchasing power | ~$50,214 | $98,400 | ~$88,051 |
The gap: Phoenix delivers approximately $48,186/year more in real purchasing power than NYC on the same $120K salary. Denver delivers $37,837/year more. These aren't marginal differences — they're the gap between building a down payment and spinning your wheels.

Remote Work: The Salary Adjustment Risk Nobody Mentions
If you're a remote worker planning to keep your NYC salary after relocating, the purchasing power numbers above apply directly. But there's a catch that erases a significant portion of the advantage: employer geographic pay bands.
Many large employers in tech, finance, and consulting use location-based salary tiers. A $120K NYC-banded role can be adjusted downward to a Phoenix-band equivalent of $90,000–$105,000 if you update your home address in HR systems. A $15K–$30K income reduction from a geo-pay adjustment would eliminate roughly one-third to two-thirds of the Phoenix purchasing power gain modeled above.
Before finalizing your relocation, get explicit written confirmation of your employer's remote-work location policy. If they don't geo-adjust, you capture the full $48K annual gain. If they do, you need to rerun every number in this post with your actual post-move salary. For a detailed model of how this plays out across no-income-tax vs. income-tax city pairs, the Seattle vs. Kansas City geo-arbitrage breakdown runs through the math step by step.
The Transition Cost Reality Check
Moving out of New York is expensive. A professional one-way move from NYC to Phoenix typically runs $4,000–$8,000 depending on volume and distance. Add:
- Breaking a NYC lease early: $3,000–$8,000 (typically 1–2 months' rent as penalty)
- New Phoenix security deposit: $1,550–$3,100 (1–2 months' rent)
- Total first-year transition friction: $8,550–$19,100
At the Phoenix purchasing power advantage of ~$48K/year, you break even on transition costs in 2–5 months of living there. The move pays for itself quickly — but only if you model the complete picture, not just the income tax line.
The Verdict
New York City's population decline makes financial sense. On $120K, the numbers consistently favor leaving — and Phoenix leads Denver on purchasing power by roughly $10,000/year in the renting scenario. But the Sunbelt isn't a uniform win:
- Phoenix renters capture the full income tax and rent advantage — the strongest financial position of the three cities
- Phoenix buyers need to model the rising luxury market's effect on mid-tier supply, current mortgage rates, and their purchase-price break-even carefully
- Denver buyers face a higher sticker price but a more stable mid-range housing market with slightly lower luxury speculation pressure
- Remote workers must confirm their employer's geo-pay policy before counting any of these numbers as real
The income tax savings are real. The housing savings are real. But both are sensitive to whether you're renting or buying, what you pay for the home, and whether your employer lets you keep the salary that makes the math work.
