You'd need $97,100 in Arizona to hold what $100,000 holds in Illinois. Here's every line that moves, in dollars.
That's $2,900 less than what you earn now, after 2026 federal tax, state tax at both ends, and price levels of 100.0 in Illinois against 100.7 in Arizona, where 100 is the national average.
The tax line is the first thing people check and the last thing that should decide it. Price levels in Illinois and Arizona are 0.7 index points apart, so the household basket costs about the same in both.
So $100,000 in Illinois is matched by $97,100 in Arizona. You can take $2,900 less and be no worse off.
Five income levels, each one run through the whole calculation twice. Single filer, standard deduction, 2026 brackets, and each state's own price level applied to what survives.
| Illinois salary | Take-home there | Real value | Arizona salary to match | Difference |
|---|---|---|---|---|
| $60,000 | $47,565 | $47,565 | $58,500 | −$1,500 |
| $80,000 | $61,295 | $61,295 | $77,600 | −$2,400 |
| $100,000 | $74,375 | $74,375 | $97,100 | −$2,900 |
| $150,000 | $106,511 | $106,511 | $145,500 | −$4,500 |
| $200,000 | $139,172 | $139,172 | $194,500 | −$5,500 |
Real value is take-home pay divided by the state price level, which is BEA's own method for comparing incomes across places. It answers what a salary would buy in an average American state, so two very different places can be set side by side on the same terms.
| Salary | Illinois | Arizona | Difference |
|---|---|---|---|
| $60,000 | $2,8254.7% | $1,2912.2% | −$1,534 |
| $80,000 | $3,8154.8% | $1,7912.2% | −$2,024 |
| $100,000 | $4,8054.8% | $2,2912.3% | −$2,514 |
| $150,000 | $7,2804.9% | $3,5412.4% | −$3,739 |
| $200,000 | $9,7554.9% | $4,7912.4% | −$4,964 |
Illinois takes $4,805 of a $100,000 salary, an effective 4.8%. Arizona takes $2,291, or 2.3%. That's $2,500 a year less.
The gap grows with income: $1,534 at $60,000, $4,964 at $200,000. So if this move comes with a promotion attached, the tax side of it gets better rather than staying put.
Price parity is BEA's measure of what the same basket costs in different places, with 100 as the national average. Illinois scores 100.0 and Arizona scores 100.7, which is close enough that the index isn't deciding anything.
At $100,000 the price difference is worth about $2,000 a year, which is small enough to disappear inside the choice of neighbourhood. State averages hide a lot, and at this margin the metro you land in matters more than the state line.
One caveat that applies in both directions. A state figure is an average across every city, town and rural county in it, and the spread inside a big state is wider than the spread between most pairs of states. If you already know which metro you're moving to, the city-level pages are the more precise answer.
Hold the salary at $100,000 and move states. Federal tax and FICA don't change, so exactly two things do: what the state takes, and what things cost.
| Line | Illinois | Arizona |
|---|---|---|
| Gross salary | $100,000 | $100,000 |
| Federal income tax | −$13,170 | −$13,170 |
| Social Security and Medicare | −$7,650 | −$7,650 |
| State income tax | −$4,805 | −$2,291 |
| Take-home pay | $74,375 | $76,889 |
| Adjusted for state prices (100.0 against 100.7) | $74,375 | $76,354 |
Net of everything, the same $100,000 is worth $2,000 more a year in Arizona. Of that, $2,500 is the state tax line and $500 is the price level. Those two are the entire difference, because everything else about a US paycheck is federal.
A state figure averages over every city and county in it, and the spread inside Arizona is wider than the gap between most pairs of states. If you already know where you're landing, these are the city-level numbers on a $100,000 salary.
Your salary, your two cities, the same federal price data. Takes about fifteen seconds.
Compare my citiesOn the same $100,000 salary you end up about $2,000 a year better off in Arizona. That's inside the range that a single change of neighbourhood or commute would swamp.
Which means this move doesn't decide itself on money. The break-even is $97,100, close enough to $100,000 that the rest of the decision is about everything the numbers don't cover.
One thing this page can't tell you: it assumes you buy roughly what an average household buys, and housing dominates that basket. If you own outright, carry a fixed mortgage, or split rent several ways, the price adjustment overstates your case in both directions. Illinois and Arizona are averages, and averages hide neighbourhoods.

The breakdown, then about one email a year. No sales pitch, unsubscribe any time.About $97,100. That holds the same purchasing power once 2026 federal tax, Illinois and Arizona state tax, mandatory state payroll taxes, and each state's price level have all been applied. At $60,000 the match is $58,500, and at $200,000 it's $194,500.
On a $100,000 salary, Illinois takes $4,805 and Arizona takes $2,291, so you save about $2,514 a year. Both schedules are progressive, so the saving is a different number at a different income.
They're close. Illinois scores 100.0 and Arizona scores 100.7 on the Bureau of Economic Analysis price parity index, a difference of 0.7 index points. These are statewide averages, and the spread inside a large state is wider than the gap between most pairs of states, so a specific metro can run against the state figure.
No. Everything on this page is a recurring annual figure: tax, price levels and purchasing power on an ongoing salary. A move also carries one-off costs, and this page states none of them because we hold no data on them and won't invent it.
Price levels are Regional Price Parities from the US Bureau of Economic Analysis, 2024 vintage, which is the federal government's official measure of geographic price differences. Tax figures are 2026 federal brackets from IRS Rev. Proc. 2025-32 plus each state's 2026 schedule. States whose 2026 figures could not be confirmed against a primary source do not get a page at all.
