Colorado vs Oklahoma
A tax calculator says the difference is $1,240 a year. Once you count what a dollar actually buys in each, Oklahoma is $11,086 ahead — $110,858 over 10 years.
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.

A pay cut of up to $14,781 (14.8%) still leaves you level.
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: Colorado and Oklahoma 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
A tax calculator says Colorado. The right answer is Oklahoma, by $11,086 a year
This is one of the 324 state pairs out of 1,275 where the two answers point at different states, and it is worth understanding why before trusting any comparison of these two. On $100,000 with a $400,000 home, Colorado leaves you $1,240 more in take-home. That figure is correct. It is also the wrong basis for the decision.
Because Colorado is the more expensive place to spend it. On the Bureau of Economic Analysis price index Colorado is 103.1 and Oklahoma is 87.8, national average 100. Deflate each take-home by where it gets spent and the ranking inverts: $71,722 in Colorado against $82,808 in Oklahoma. Oklahoma wins by $11,086 a year — the opposite state to the one the tax figure names, and $110,858 over 10 years.
Where the two sit nationally: Colorado is the 13th most expensive place to live of the 51 — the 50 states and the District of Columbia — and Oklahoma is 49th. Housing, the component that moves most, is 127.4 against 62.8.
Grey columns are what a year of Colorado and a year of Oklahoma 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.
Why the two answers disagree, and which one to use
It is worth being precise about what is happening here, because "the cost of living is higher" is the kind of phrase that gets used to wave away an inconvenient number, and this is not that.
Both figures are correct measurements of different things. Take-home answers: how many dollars land in your account? Colorado wins that, by $1,240. Purchasing power answers: how much can those dollars buy where you will be spending them? Oklahoma wins that, by $11,086. The second question is the one you are actually asking when you ask where to live.
The mechanism is arithmetic rather than opinion. Divide the Colorado take-home by its price level and you get $71,722; do the same in Oklahoma and you get $82,808. The whole reversal comes from a price index of 103.1 against 87.8, published by the Bureau of Economic Analysis for exactly this purpose.
Where the nominal figure is the right one to use: if you are working in one state and spending in another — a border commute, a remote job you will leave, a posting you will not settle in — then your costs do not follow the state you are paid in, and take-home is what matters. That is a real case and it is why both numbers appear on this page rather than only the one that supports the conclusion.
Where the money actually goes, line by line
Before the layers, the conclusion they lead to: on this pair the tax code is a side issue. The price level moves the answer 12.6 times more than the largest single tax difference between Colorado and Oklahoma. The five layers still deserve walking, because they are what people arrive believing decides it:
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 — $3,692 in Colorado, $3,955 in Oklahoma. A difference of $263.
Property tax — $1,543 in Colorado, $2,520 in Oklahoma on a $400,000 home, at each state's median local rate. This is bigger than the income tax difference, and it runs the other way — which is the whole reason the headline number disappoints.
Local income tax — zero on both sides. Both Colorado and Oklahoma keep income tax at the state level only, so the figures above are complete rather than approximations.
Total: $26,055 in Colorado against $27,295 in Oklahoma — 26.1% and 27.3% of gross.
And Colorado housing costs 102.9% more
The cost of living gap between Colorado and Oklahoma is almost entirely a housing gap, and that is only visible because the Bureau of Economic Analysis Regional Price Parity publishes its components separately rather than as one blended number. 100 is the national average.
Cheaper in Oklahoma than ColoradoDearer in Oklahoma than Colorado
Each bar is how far apart Colorado and Oklahoma 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 — 103.1 in Colorado, 87.8 in Oklahoma. A gap of 15.3 points.
Housing — 127.4 against 62.8. A gap of 64.6 points, 4.2× the headline gap. This is what people mean when they say somewhere is expensive.
Goods — 98.7 against 93.8, 4.9 points apart — 13.2 times narrower than the housing gap — and typical: across all 1,275 pairs the median is 2.7 points for goods against 24.9 for housing. Blended into one figure, what you are reading is mostly housing wearing a general label.
Utilities — 85 against 73.9. 11.1 points apart, close enough not to change a decision.
Which half of this reaches you depends on whether you buy. Renting, the real difference between Colorado and Oklahoma is $12,460 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 $11,086. So renting is where the gap is widest here, by $1,374 — unusual, and it means buying erodes the advantage rather than compounding it.
The number to take into a salary negotiation: $85,219
This is the question people are actually asking and almost nobody answers: what would I need to earn in Oklahoma to live exactly as well as I do on $100,000 in Colorado?
$85,219. That is 14.8% less than you earn now. You could take a pay cut of $14,781 moving to Oklahoma and be no worse off — which is a very different conversation to have with a recruiter than "Oklahoma has lower taxes".
The dashed line is the salary you earn now. The solid line is what matches it in Oklahoma. 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 shortcut happens to land here: scaling by the ratio of price levels gives $85,160 against a true $85,219, $59 apart. A coincidence of these two price levels at this salary rather than a rule — on most of the other 1,274 pairs the same shortcut is out by thousands.
The figure belongs to the two states and your income. On $40,000 the match in Oklahoma is $35,349, 11.6% below what you earn; on $250,000 it is $211,522, 15.4% below. The relationship bends by 3.8% across that range.
"Colorado" and "Oklahoma" are not places you can compare
Every figure above uses each state's median local property tax rate — its counties in Colorado, its counties in Oklahoma — and that is a simplification the page should own rather than hide.
Oklahoma has 77 counties, and the effective property tax rate runs from 0.4% in McCurtain County to 1.03% in Cleveland County — 2.6 times. On a $400,000 home that is a spread of $2,506 a year, without leaving the state.
64 counties. Each dot is one. The spread is 3.0 times from end to end, which is why a state average is not a number you can plan with.
Colorado has 64 counties, and the effective property tax rate runs from 0.21% in Jackson County to 0.62% in Broomfield County — 3.0 times. On a $400,000 home that is a spread of $1,642 a year, without leaving the state.
So the honest version of this question is not "Colorado or Oklahoma" but which county. Picking the cheapest county in Oklahoma against the dearest county in Colorado swings the property tax line by $860 a year; the reverse choice swings it $3,287 the other way. Against a headline difference of $11,086, the county is not a detail — it is most of the decision.
Neither Colorado nor Oklahoma lets its counties levy their own income tax, so that layer is genuinely zero here rather than unmodelled — one of the 1,225 pairs out of 1,275 where it does not apply. It is the reason Colorado and Oklahoma are easier to compare honestly than most neighbours are.
Over 10 years: $110,858
Nobody moves for one year, and almost no comparison prices the decision over the horizon on which it is actually made.
At $11,086 a year of real difference, 10 years in Oklahoma instead of Colorado is worth $110,858 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 takes until year 2 for the move to pay for itself. That is the figure a per-year comparison hides.
The first slice of it is not yours, though. Reckoning $15,000 for removal, fees and selling costs — this page's assumption, not a sourced figure — at $11,086 a year it takes 1.4 years to earn back, so a stay shorter than that loses money on a move the annual figure calls a win.
At three horizons: $33,257 over three years, $110,858 over 10, $332,574 over thirty.
None of those figures contains the one variable that could overturn them: the same job rarely pays the same in Colorado and Oklahoma. That is what the $85,219 break-even above is for — it prices an offer instead of assuming the offer is identical.
You could take a $14,781 pay cut to move to Oklahoma and be no worse off
That is the version of this comparison worth taking into a negotiation, and it is not a figure any tax calculator produces.
Matching your $100,000 standard of living in Colorado takes $85,219 in Oklahoma — 14.8% less than you earn now. So an offer of $85,219 is not a downgrade, and an offer above it is a raise however it looks on paper.
The reverse framing is the one recruiters use, and it is worth being able to answer: a company in Colorado offering to match your current salary is offering you less than the Oklahoma job at $85,219. On 10 years the difference is $110,858.
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.
Where to go next
Questions
- Is it cheaper to live in Colorado or Oklahoma?
- Oklahoma, by $11,086 a year in real purchasing power on $100,000 with a $400,000 home. The take-home difference is only $1,240; the rest comes from the cost of living, where Colorado indexes at 103.1 and Oklahoma at 87.8 against a national average of 100.
- How much do I need to earn in Oklahoma to match $100,000 in Colorado?
- $85,219 — 14.8% less than you earn now, so a pay cut of up to $14,781 still leaves you level. That accounts for federal tax, FICA, state tax, property tax and the price level in each state.
- What are the taxes in Colorado vs Oklahoma?
- On $100,000: state income tax of $3,692 in Colorado against $3,955 in Oklahoma, and property tax of $1,543 against $2,520 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 Oklahoma really have lower property tax?
- That depends entirely on the county, which is why a state-level answer is not much use. Oklahoma runs from 0.4% in McCurtain County to 1.03% in Cleveland County — 2.6 times, or $2,506 a year on a $400,000 home. The median is 0.63%.
- How much is the difference over 10 years?
- $110,858 in today's purchasing power, at $11,086 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.
