Alaska vs Arizona
On $100,000 these two come out level once cost of living is counted — which the tax rates alone would never tell you.
Property tax is set by counties, not states. Inside Texas alone the rate varies six times over, so this is the single choice that changes the answer most.

Who worked this out, and what it is built on
I build and maintain every comparison on this site — 1275 state pairs so far, on the same engine that runs the tax calculators for all 50 states and 3,143 counties. This is not a template with two names swapped into it: Alaska and Arizona are run through the actual rules of each place, and if the numbers say the move is not worth it, that is what the page says.
Four sources, and one deliberate refusal. Federal figures from the IRS revenue procedure. State rates read one state at a time off each state’s own department of revenue. County property tax from the US Census Bureau. Cost of living from the Bureau of Economic Analysis Regional Price Parities, 2024 — and not from Numbeo or any other crowd-sourced index, because those are filled in by users, publish no methodology, and cannot be cited. That single choice is most of why the cost-of-living numbers here differ from everybody else’s.
When I get something wrong I publish the correction with the date and what it cost — including the two mistakes on these pages I found myself. Data last verified September 1, 2026.

- The nine states with no income tax— and what they charge instead
On $100,000, Alaska and Arizona come out level — and the rates are nothing like level
Two states that finish in a dead heat on a measure built out of five taxes and a price index is not a boring result; it means several large differences are cancelling. On $100,000 with a $400,000 home the purchasing power is $74,525 in Alaska and $74,502 in Arizona — $23 apart, which on this salary is noise.
The parts are not level at all. State income tax is $0 against $1,998, property tax $2,866 against $2,159, and the price index 102.4 against 100.7. Any one of those quoted alone would look like a decisive argument for one side. Together they come to nothing, which means for this pair the money is genuinely not the deciding factor and you can choose on everything else.
Where the two sit nationally: Alaska is the 14th most expensive place to live of the 51 — the 50 states and the District of Columbia — and Arizona is 17th. Housing, the component that moves most, is 93.8 against 106.8.
Grey columns are what a year of Alaska and a year of Arizona are worth in the same money. The bars between them are each thing that changes, in the order it changes: green adds, amber takes away.
Where the money actually goes, line by line
Five separate taxes. On this pair the state income tax genuinely is the largest difference — $1,998 — which is less common than the coverage of this subject suggests:
Federal income tax — $13,170 either way. Identical, because it is federal. Any comparison that shows a difference here is wrong.
FICA — $7,650 either way. Also federal, also identical.
State income tax — $0 in Alaska, $1,998 in Arizona. Alaska does not levy one at all, which is the fact that sells the move — and, as the next line shows, not the fact that decides it.
Property tax — $2,866 in Alaska, $2,159 in Arizona on a $400,000 home, at each state's median local rate. Smaller than the income tax gap here, which is not usually the case.
Local income tax — zero on both sides. Alaska has none at any level, state or local — and that holds for all nine states without a state income tax, none of which lets a county or city levy one either. The two go together.
Total: $23,686 in Alaska against $24,976 in Arizona — 23.7% and 25.0% of gross.
And Arizona housing costs 13.9% more
These two states cost almost the same to live in, which is why the tax difference survives into the answer. The index is the Bureau of Economic Analysis Regional Price Parity — official, published per state, 100 is the national average — and it is worth looking at the components even when the headline barely moves, because they can disagree with it.
Cheaper in Arizona than AlaskaDearer in Arizona than Alaska
Each bar is how far apart Alaska and Arizona are on that component, and which way. Housing almost always runs several times wider than everything else — which is why a single blended index tells you very little.
All items — 102.4 in Alaska, 100.7 in Arizona. A gap of 1.7 points.
Housing — 93.8 against 106.8. A gap of 13.0 points, 7.6× the headline gap. This is what people mean when they say somewhere is expensive.
Goods — 106.3 against 95.4, 10.9 points apart — wide for goods: across all 1,275 state pairs the median goods gap is 2.7 points against 24.9 for housing, so on this pair the shopping basket genuinely differs and not just the rent.
Utilities — 119 against 92.3. 26.7 points, the second widest component after housing on this pair, and large enough to matter to anyone heating or cooling a big house.
Which half of this reaches you depends on whether you buy. Renting, the real difference between Alaska and Arizona is $678 a year — property tax comes out of your side entirely, and what is left is the price level. Buying a $400,000 home it is $23. So renting is where the gap is widest here, by $655 — unusual, and it means buying erodes the advantage rather than compounding it.
The number to take into a salary negotiation: $100,034
This is the question people are actually asking and almost nobody answers: what would I need to earn in Arizona to live exactly as well as I do on $100,000 in Alaska?
$100,034. That is 0.0% more than you earn now. Anything less than $100,034 and the move costs you money however it is presented.
The dashed line is the salary you earn now. The solid line is what matches it in Arizona. If the relationship were a simple multiplier the two would be parallel — they are not, because brackets, the Social Security ceiling and a property tax that does not move with income all bend it.
The obvious shortcut fails here, and by a measurable amount. Scaling your salary by the ratio of price levels — $100,000 × 100.7/102.4 — gives $98,340. The answer is $100,034, so the shortcut is $1,694 too low: brackets, the Social Security ceiling and a property tax that ignores income all bend the line the shortcut assumes is straight.
The figure belongs to the two states and your income. On $40,000 the match in Arizona is $39,060, 2.4% below what you earn; on $250,000 it is $253,241, 1.3% above. The relationship bends by 3.6% across that range.
Over 10 years: $232
Ten years of a difference this small is still a small number: $232. Which is the point — on a horizon long enough for compounding to matter, this pair still does not separate on money.
At $23 a year of real difference, 10 years in Alaska instead of Arizona is worth $232 in today's purchasing power — before compounding anything you might invest it in.
The line starts below zero because moving costs about $15,000 and lands entirely in year one. It pays for itself inside the first year. That is the figure a per-year comparison hides.
And it is slower to arrive than the annual figure suggests. Reckoning $15,000 for removal, fees and the cost of selling — an assumption this page makes, not a figure from a source — at $23 a year it takes 646.4 years to recover — so the annual figure only becomes yours from year 648.
At three horizons: $70 over three years, $232 over 10, $696 over thirty — and the three-year figure does not clear the cost of getting there.
None of those figures contains the one variable that could overturn them: the same job rarely pays the same in Alaska and Arizona. That is what the $100,034 break-even above is for — it prices an offer instead of assuming the offer is identical.
Choosing the county matters more than choosing the state here
This comparison is worth $23 a year. Choosing where inside Alaska to live is worth $6,698 a year on the same $400,000 home — 288.6 times as much.
Alaska has 26 boroughs and census areas and the effective property tax rate runs from 0.08% in Copper River Census Area to 1.76% in Dillingham Census Area. Move to the wrong borough or census area in the better state and you have given back more than the move gained you, twice over.
Which reframes the question. Rather than "Alaska or Arizona", the decision that carries the money is which borough or census area inside Alaska — and the answer is not visible on any comparison that stops at the state line. Set both in the calculator above and every figure on this page recomputes on your actual rates rather than two medians.
The same logic applies to the losing side: Arizona has counties cheaper than the median used here too, and for a reader who is staying put, moving county at home may be the better version of this decision.
Where every number here comes from
Four sources, each read off the body that publishes it:
US Bureau of Economic Analysis — Regional Price Parities by State and Metro Area, 2024 (released 19 February 2026) — read 2026-09-08. https://www.bea.gov/data/prices-inflation/regional-price-parities-state-and-metro-area
IRS — Revenue Procedure for the tax year (federal brackets, standard deduction and FICA) — read 2026-09-02. https://www.irs.gov/
Each state's own department of revenue (state income tax rates and deductions), verified one state at a time — read 2026-09-02. https://estimatetax.net/sources/
US Census Bureau, American Community Survey (county effective property tax rates) — read 2026-08-31. https://data.census.gov/
The cost of living index is the part worth checking, because it is where comparison sites usually reach for something crowd-sourced. The Regional Price Parities are produced by the Bureau of Economic Analysis, cover every state and metro area, and are published with a methodology document. The figures here are the 2024 release and are not extrapolated forward.
And what this page does not model:
— The cost of living index is the BEA's Regional Price Parity for 2024, the most recent published. It is not extrapolated to the current year, and it is a state-wide average — inside a state, a metro area and a rural county differ by more than most state pairs do.
— Moving costs, state transfer taxes on buying a home, and the cost of selling the one you have are not included. On a short stay they can outweigh every annual difference on this page.
— Sales tax is not modelled. It is inside the BEA index — that is what a price parity measures — but it is not broken out separately here.
— The comparison assumes the same salary in both places unless you change it. In practice a job in a high-cost state usually pays more, which is exactly what the break-even figure is for.
— Health insurance, childcare and car insurance vary enormously by state and are only inside the index as averages. If any of the three is a large part of your budget, it deserves its own arithmetic.

Questions
- Is it cheaper to live in Alaska or Arizona?
- On $100,000 they come out level — $74,525 of purchasing power in Alaska against $74,502 in Arizona, a difference of $23 a year. That is unusual and worth knowing, because the headline rates are not level at all: state income tax is $0 against $1,998 and property tax $2,866 against $2,159. They cancel out.
- How much do I need to earn in Arizona to match $100,000 in Alaska?
- $100,034 — 0.0% more. That accounts for federal tax, FICA, state tax, property tax and the price level in each state.
- What are the taxes in Alaska vs Arizona?
- On $100,000: state income tax of $0 in Alaska against $1,998 in Arizona, and property tax of $2,866 against $2,159 on a $400,000 home at median county rates. Federal tax and FICA are identical in both — $13,170 and $7,650 — so any comparison showing a difference there is wrong.
- Does Arizona really have lower property tax?
- That depends entirely on the county, which is why a state-level answer is not much use. Arizona runs from 0.36% in Greenlee County to 0.84% in Apache County — 2.3 times, or $1,917 a year on a $400,000 home. The median is 0.54%.
- How much is the difference over 10 years?
- $232 in today's purchasing power, at $23 a year. That excludes moving and housing transaction costs, which land in year one and can outweigh everything else on a short stay.
- Where does your cost of living data come from?
- The Bureau of Economic Analysis Regional Price Parities for 2024, an official index covering every state and metro area with a published methodology. Not a crowd-sourced database — and it comes broken into housing, goods, utilities and services, which matters because housing moves several times more than anything else.
