OVERVIEW
Arizona and New Jersey represent perhaps the most dramatic total tax contrast of any two US states. Arizona has the lowest flat income tax in the US (2.5%), while New Jersey has one of the highest progressive structures (up to 10.75%) plus the highest property tax rate in the US (2.47%). On $100,000 income, Arizona saves $7,242/year in income tax alone. Add property tax: a $400k home costs $9,880/year in NJ vs $2,480 in Arizona — a $7,400 difference. Combined: a $100k earning homeowner with a $400k home saves approximately $14,642/year in Arizona. Over 10 years: $146,420. This is why the NJ-to-AZ migration corridor has accelerated dramatically since 2020.

FAQ

Frequently Asked Questions

Is Arizona vs New Jersey really the biggest tax difference between US states?

For homeowners at middle-to-high incomes, yes — it's one of the most dramatic. The combination of NJ's 2.47% property tax (highest in US) and progressive income tax (up to 10.75%) vs AZ's 2.5% flat income tax and 0.62% property tax creates a gap that can reach $15,000-$25,000/year for a homeowning family earning $200k. States without income tax (FL, TX, NV) beat AZ on income tax alone, but their property taxes are often higher than AZ. The AZ vs NJ total burden differential may be the largest of any comparable state pairing.

How much do New Jersey families actually save moving to Arizona?

For a family earning $200k with a $600k home: NJ income tax ~$18,742 + property tax ~$14,820 = $33,562/year. AZ income tax $5,000 + property tax $3,720 = $8,720/year. Annual savings: $24,842. Over 10 years: $248,420 — before investment returns. Even after accounting for AZ's higher sales tax (spending $80k/year: AZ costs ~$1,420 more in sales tax), net savings remain approximately $23,400/year. This is why NJ → AZ is one of the fastest-growing migration flows in the US.

What drives New Jersey's extremely high property taxes?

New Jersey's 2.47% effective property tax rate (highest in the nation) is structural: (1) 565 independent municipalities each levy taxes locally; (2) NJ funds schools almost entirely through local property taxes rather than state revenue; (3) High public employee pension obligations at municipal level; (4) Dense urban services cost more per square mile. The result: a $500k NJ home typically carries $12,000-$15,000/year in property taxes, while the same $500k Arizona home pays ~$3,100.

Does moving from NJ to AZ affect federal taxes?

Yes, in multiple ways: (1) The SALT deduction cap ($10,000 federal limit) means most NJ homeowners already can't fully deduct their property taxes federally, making the after-tax NJ burden even worse; (2) Moving to AZ reduces total itemized deductions (lower state taxes to deduct), but the $10k SALT cap means this is already largely irrelevant for high earners; (3) AZ's lower income tax means lower AGI adjustments — but this has minimal federal impact. Net federal effect of moving NJ → AZ is minimal, while state-level savings are enormous.

Is Phoenix comparable to North Jersey suburbs for quality of life?

It depends on priorities. North Jersey wins for: NYC access (30-60 min commute), school quality (NJ #1-2 nationally), four seasons, cultural density, transit options, and coastal access (Jersey Shore). Phoenix/Scottsdale wins for: weather (299 sunny days vs NJ's 205), outdoor recreation, newer housing stock, lower cost of living, no traffic gridlock on NJ Turnpike scale, and massive tax savings. Families willing to embrace a Southwest lifestyle (and leave NYC proximity) typically find the $15,000-$25,000/year savings transformative.
