Colorado taxes wages at a flat 4.4% state rate in 2026 — the same rate whatever you earn — on top of federal income tax and FICA. Single filers get a standard deduction of $16,100. Use the calculators below to see your exact 2026 take-home pay in Colorado, check the sales tax on a purchase, and estimate a mortgage payment with Colorado property taxes factored in.
State Paycheck Calculator 2026
Estimate take-home pay after federal tax, FICA and your state’s income tax for the 2026 tax year.
How it works: the 2026 federal standard deduction ($16,100 single, $32,200 married filing jointly) comes off your salary first, then the 2026 federal brackets (10%–37%). FICA is applied properly: 6.2% Social Security on the first $184,500 of wages (2026 wage base), 1.45% Medicare on all wages, plus 0.9% additional Medicare on wages above $200,000 single / $250,000 married filing jointly. State tax applies each state’s own standard deduction/exemptions, then its brackets or flat rate. Local income taxes are not included — many cities and counties (e.g. New York City, Philadelphia, most of Ohio, Maryland counties, Indiana counties, Kentucky) levy their own payroll taxes on top of the state tax.

The statewide base sales tax rate in Colorado is 2.9% in 2026. Cities and counties can add their own local tax on top of the base rate — enter any local add-on below to see the full tax and total price.
Sales Tax Calculator 2026
Estimate the sales tax and total price using each state’s base rate (2026), plus any local add-on.
State base rates are the 2026 state-level rates (local add-ons excluded). Actual combined rates vary widely by city and county — many localities add 1–5%. Five states have no statewide sales tax (Alaska, Delaware, Montana, New Hampshire, Oregon), though some localities still levy local taxes.
Mortgage calculator for Colorado homes
The average effective property tax rate in Colorado is about 0.48% of a home’s value per year. When you use the mortgage calculator below, enter roughly that percentage of the home price in the yearly property tax field for a realistic Colorado monthly payment.
Mortgage Payment Calculator
Work out your monthly principal & interest payment, total interest and the true total cost of your loan.
How it works: your loan amount (price minus down payment) is repaid in equal monthly instalments using the standard amortisation formula, so early payments are mostly interest and later ones mostly principal. Property tax and insurance, if entered, are simply spread evenly across each month. Your actual rate and payment will depend on your lender, credit profile and the deal you choose.
2.90% is the lowest state sales tax rate in America that isn’t zero. Colorado also runs one of the simplest income taxes anywhere — a flat 4.40% that borrows the federal government’s homework instead of doing its own. And yet Denver shoppers routinely pay close to 8% at the register. Colorado’s low headline numbers are real. They’re just not the whole story.
Income tax in Colorado in 2026
Flat. 4.40%. One rate for everyone.
But here’s the mechanic that makes Colorado different: the state starts from your federal taxable income. Washington works out your income, subtracts the federal standard deduction, hands Colorado a number — and Colorado taxes that number at 4.40%. There’s no separate Colorado standard deduction to claim because the federal one is already baked into the starting point.
That has a practical upside. If federal law gives you a bigger deduction, your Colorado tax drops automatically, without Colorado changing a thing. And filing feels simpler, because the hardest calculation on your state return was already done on your federal one.
No brackets also means no bracket creep. Earn a bonus, cross no thresholds, pay the same 4.40% on it as on everything else. Compare that with Connecticut’s seven brackets and vanishing exemption, and Colorado’s system looks almost stubbornly straightforward.
Worked example: $75,000 salary, single filer
Step 1: Colorado starts from federal taxable income. $75,000 minus the federal standard deduction of $16,100 gives state taxable income of $58,900.
Step 2: Multiply by 4.40%. Colorado state tax is $2,591.60 — an effective rate of 3.46% of your gross salary, lower than the flat rate suggests because the federal deduction shrank the base first.
Step 3: Federal income tax on that same $58,900 of taxable income is $7,670.00.
Step 4: FICA comes to $5,737.50: Social Security $4,650.00 plus Medicare $1,087.50.
Step 5: $75,000 minus $2,591.60, $7,670.00 and $5,737.50 leaves take-home pay of $59,000.90 a year — about $2,269.27 every two weeks.
Sales tax in Colorado
The state base rate is just 2.90%, the lowest non-zero state rate in the US. State tax on a $1,000 purchase? $29.
The catch is… everything else. Cities, counties and special districts pile their own taxes on top, and they pile high. The average combined rate lands around 7.89%, so that $1,000 purchase typically costs closer to $79 in total tax depending on where you buy it. Colorado’s state government charges almost nothing and lets local government do the charging instead. Whether that’s better depends entirely on your ZIP code.
Property tax in Colorado
Homeowners get a quieter deal. Colorado’s average effective property tax rate is 0.48%, a statewide average, tying Arizona among the lower states nationally.
A $300,000 home runs about $1,440 a year in property tax. Residential assessment rates in Colorado are kept low relative to commercial property, which helps keep homeowner bills down even in pricey metro areas. Your county’s mill levies will set the exact figure, but the statewide picture is a friendly one.
Frequently asked questions
Why does Colorado start from federal taxable income?
Simplicity, by design. Colorado takes the taxable income figure from your federal return and applies its flat 4.40% rate. It means the federal $16,100 standard deduction automatically lowers your state tax too — no separate state deduction to claim.
Is 4.40% really what everyone pays?
On their taxable income, yes — there’s one flat rate and no brackets. Your effective rate on gross pay comes out lower, 3.46% on a $75,000 salary, because the tax only applies after the federal standard deduction.
If the state sales tax is 2.90%, why did I pay nearly 8%?
Local taxes. Cities, counties and special districts add their own sales taxes on top of the state’s 2.90%, and the average combined rate is about 7.89%. The state rate is the floor, not the total.
How does Colorado compare with its neighbors?
Its 4.40% flat income tax sits in the middle of the pack, its 0.48% average property tax is low, and its combined sales tax is where the real cost hides — the opposite pattern to a state like California, where the income tax does the damage.
