Colorado vs District of Columbia
A tax calculator says the difference is $2,604 a year. Once you count what a dollar actually buys in each, Colorado is $6,807 ahead — $68,074 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.

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 District of Columbia 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.

Colorado or District of Columbia is a housing decision: District of Columbia housing runs 21.7% dearer
The tax difference between Colorado and District of Columbia is real but it is not what decides this one. On $100,000 with a $400,000 home, take-home moves by $2,604 a year. Housing moves by far more: the housing component of the official price index is 127.4 in Colorado against 155 in District of Columbia, a gap of 27.6 points against just 6.8 on the index as a whole.
Which means a single blended cost-of-living number would hide the only variable that matters here. Put the housing gap into the arithmetic and Colorado comes out $6,807 a year ahead in what the money buys — $68,074 over 10 years. If you rent a small flat, most of that advantage never reaches you; if you buy a family house, it is understated.
Where the two sit nationally: District of Columbia is the 3rd most expensive place to live of the 51 — the 50 states and the District of Columbia — and Colorado is 13th. Housing, the component that moves most, is 127.4 against 155.
Grey columns are what a year of Colorado and a year of District of Columbia 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, and here they matter but they do not win: the price level shifts the answer by $4,281 against $1,840 for the biggest tax gap. Both are in play, which makes this one of the pairs where the layers are worth reading closely:
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, $5,532 in District of Columbia. A difference of $1,840.
Property tax — $1,543 in Colorado, $2,308 in District of Columbia 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. Both Colorado and District of Columbia keep income tax at the state level only, so the figures above are complete rather than approximations.
Total: $26,055 in Colorado against $28,659 in District of Columbia — 26.1% and 28.7% of gross.
And District of Columbia housing costs 21.7% more
The cost of living gap between Colorado and District of Columbia 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 District of Columbia than ColoradoDearer in District of Columbia than Colorado
Each bar is how far apart Colorado and District of Columbia 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, 109.9 in District of Columbia. A gap of 6.8 points.
Housing — 127.4 against 155. A gap of 27.6 points, 4.1× the headline gap. This is what people mean when they say somewhere is expensive.
Goods — 98.7 against 106.5, 7.8 points apart — 3.5 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 112.8. 27.8 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 Colorado and District of Columbia is $6,205 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 $6,807. So buying widens the gap by $603: the more house you own, the more this comparison is worth to you.
The number to take into a salary negotiation: $112,096
This is the question people are actually asking and almost nobody answers: what would I need to earn in District of Columbia to live exactly as well as I do on $100,000 in Colorado?
$112,096. That is 12.1% more than you earn now. Anything less than $112,096 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 District of Columbia. 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 × 109.9/103.1 — gives $106,596. The answer is $112,096, so the shortcut is $5,500 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 District of Columbia is $44,088, 10.2% above what you earn; on $250,000 it is $286,077, 14.4% above. The relationship bends by 4.2% across that range.
"Colorado" and "District of Columbia" are not places you can compare
Every figure above uses each state's median local property tax rate — its counties in Colorado, its districts in District of Columbia — and that is a simplification the page should own rather than hide.
District of Columbia is a single taxing jurisdiction: one rate, 0.58%, and no county to choose. That is unusual — 49 of the 51 have a spread — and it makes this side of the comparison exact rather than a median.
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 District of Columbia" but which county or district. Picking the cheapest district in District of Columbia against the dearest county in Colorado swings the property tax line by $155 a year; the reverse choice swings it $1,487 the other way. Against a headline difference of $6,807, the county is not a detail — it is most of the decision.
Neither Colorado nor District of Columbia lets its counties or districts 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 District of Columbia are easier to compare honestly than most neighbours are.
Over 10 years: $68,074
Nobody moves for one year, and almost no comparison prices the decision over the horizon on which it is actually made.
At $6,807 a year of real difference, 10 years in Colorado instead of District of Columbia is worth $68,074 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 3 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 $6,807 a year it takes 2.2 years to earn back, so a stay shorter than that loses money on a move the annual figure calls a win.
At three horizons: $20,422 over three years, $68,074 over 10, $204,223 over thirty.
None of those figures contains the one variable that could overturn them: the same job rarely pays the same in Colorado and District of Columbia. That is what the $112,096 break-even above is for — it prices an offer instead of assuming the offer is identical.
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 Colorado or District of Columbia?
- Colorado, by $6,807 a year in real purchasing power on $100,000 with a $400,000 home. The take-home difference is only $2,604; the rest comes from the cost of living, where Colorado indexes at 103.1 and District of Columbia at 109.9 against a national average of 100.
- How much do I need to earn in District of Columbia to match $100,000 in Colorado?
- $112,096 — 12.1% more. That accounts for federal tax, FICA, state tax, property tax and the price level in each state.
- What are the taxes in Colorado vs District of Columbia?
- On $100,000: state income tax of $3,692 in Colorado against $5,532 in District of Columbia, and property tax of $1,543 against $2,308 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 District of Columbia really have lower property tax?
- District of Columbia is a single taxing jurisdiction, so there is one answer rather than a range: 0.58%, or $2,308 a year on a $400,000 home. That is unusual — in Colorado and the other 49 the rate is set county by county, and the spread inside a state is routinely wider than the gap between two.
- How much is the difference over 10 years?
- $68,074 in today's purchasing power, at $6,807 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.
