2026 · Colorado · Flat 4.4% on federal taxable income
Colorado Paycheck Calculator
Colorado does not have its own tax base. It applies 4.4% to federal taxable income, which means the federal standard deduction of $16,100 is also Colorado's, and every pre-tax deduction — 401(k), HSA, health premium — cuts the state line as well as the federal one. It also means Colorado gives nothing of its own: no dependent exemption, no state standard deduction to look up, no phase-out to model. This calculator applies the 4.4% to the same base the IRS uses.
Your Colorado paycheck, period by period
A Colorado salary is quoted per year and paid in slices: $52,000 is $1,000 a week, $2,000 every two weeks, $2,166.67 twice a month or $4,333.33 once a month. The annual total does not move; the deposit and the withholding taken from it do.
Colorado contributes one line to the stub, and on $52,000 paid every two weeks it is $60.75 per check — against $156.15 of federal income tax, $124.00 of Social Security and $29.00 of Medicare. That state line is 4.4% of $35,900, and $35,900 is exactly the federal taxable income on the same salary, because Colorado uses the federal standard deduction rather than one of its own. Paid weekly the state line is $30.38 and paid monthly it is $131.63; the annual figure, $1,579.60, is the same in all three cases.
| Pay frequency | Gross per check | Net per check | Net per year |
|---|---|---|---|
| Weekly | $1,000.00 | $815.05 | $42,382 |
| Bi-weekly | $2,000.00 | $1,630.09 | $42,382 |
| Semi-monthly | $2,166.67 | $1,765.93 | $42,382 |
| Monthly | $4,333.33 | $3,531.87 | $42,382 |
What comes out of a Colorado paycheck in 2026
Four deductions come out of a Colorado paycheck: federal income tax, Social Security, Medicare and Colorado income tax. Colorado has no state disability insurance, no paid family leave premium and no county or city wage tax, so the state contributes one line.
Federal income tax
Federal tax is progressive: each slice of taxable income carries its own rate, so a raise never re-prices the dollars already earned. For a single filer in 2026 the bands are 10% to $12,400 of taxable income, 12% to $50,400, 22% to $105,700, 24% to $201,775, 32% to $256,225, 35% to $640,600 and 37% above that. A married couple filing jointly gets bands twice as wide up to the top bracket.
Federal taxable income is salary minus pre-tax deductions minus the standard deduction: $16,100 single, $32,200 joint, $16,100 married filing separately, $24,150 head of household. A single filer on $52,000 has $35,900 of federal taxable income and pays $4,060 across the year, about 7.8% of salary, even though the last dollar sits in the 12% band.
Social Security and Medicare
Social Security takes 6.2% of gross wages up to an annual wage base of $184,500 in 2026, so the largest employee contribution is $11,439; the employer matches it. Medicare takes 1.45% of every dollar with no ceiling, plus 0.9% on wages above $200,000 single or $250,000 joint that the employer does not match. On $52,000 the two lines come to $3,224 and $754.
Colorado income tax
Colorado's calculation is the shortest on this site: take federal taxable income, multiply by 4.4%. There is no Colorado standard deduction to subtract, because the federal one is already inside the number, and there is no Colorado personal or dependent exemption at all. On $52,000 the federal taxable income is $35,900 and the Colorado tax is $1,579.60 for the year, or $60.75 per bi-weekly check.
The useful consequence is that a pre-tax deduction works twice. A 6% 401(k) deferral on $52,000 removes $3,120 from the federal base, which saves $374.40 of federal tax, and removes the same $3,120 from the Colorado base, which saves another $137.28. An HSA contribution and a Section 125 health premium behave identically. On $52,000 a 6% deferral cuts the Colorado line from $1,579.60 to $1,442.32.
The unhelpful consequence is that Colorado inherits every federal decision about what counts as income. If the federal government changes the standard deduction, Colorado's tax base changes with it and the Legislature does not have to vote. That is why the Colorado line moves between years even when the 4.4% rate has not changed.
Why Colorado taxes the federal base, and what that costs
Seven states use federal taxable income as their own starting point, and Colorado is the largest of them. The appeal is administrative: there is one set of definitions, one set of forms behind it and no separate state deduction schedule to maintain. The cost is that the state has no lever over its own base. Every federal change to the standard deduction, to the treatment of retirement contributions or to what counts as adjusted gross income flows straight into Colorado's revenue without a vote in Denver.
The rate is 4.4% for 2026, down from 4.55% a few years earlier. Colorado's rate is unusual in one more way: it can be cut by a refund mechanism rather than by a rate bill. The state's TABOR amendment caps revenue growth and requires surpluses to be refunded, and in 2022 part of the surplus was delivered as a temporary reduction in the income tax rate rather than as a cheque. A Colorado withholding table can therefore change for a reason that has nothing to do with tax policy.
Because the base is the federal base, Colorado has no dependent allowance of any kind. A household with four children pays the same Colorado tax as a single person with the same federal taxable income — the children change the federal return through the Child Tax Credit and the filing status, and change the Colorado line only to the extent that they change federal taxable income. That is the opposite of Georgia, which subtracts $4,000 per child, and of Kansas, which subtracts $2,320.
The standard deduction inheritance is worth more than it sounds. At $16,100 it is the largest single allowance on this site, and it arrives automatically. Compare Mississippi, where a filer has to add a $2,300 deduction to a $6,000 exemption and then apply a $10,000 zero band to reach $18,300 of total allowance. Colorado's figure is $16,100 with no arithmetic, and it rises every year with the federal inflation adjustment rather than sitting fixed in statute as Georgia's does.
What Colorado does not have is a second payroll line or a local wage tax. The ten states that allow county or city wage taxes do not include Colorado, and there is no state disability or paid leave premium, so a Colorado stub carries one state line and it is 4.4% of a number the IRS has already computed.
The inheritance is not fixed, which is the part that surprises people. The federal standard deduction was $12,000 when the current structure took effect and is $16,100 for 2026 — a 34% increase that Colorado received without passing a bill. On a $52,000 salary that shift alone moved $4,100 out of the Colorado base, which at 4.4% is $180.40 of tax the state no longer collects on that salary. It is also why a Colorado withholding table can change in a year when nobody in Denver voted for a tax cut.
Colorado, Kansas and Nevada on the same salary
Colorado sits between a neighbour that runs two brackets on a smaller allowance and a neighbour that charges nothing at all. The comparison below puts it against Kansas, which runs 5.2% and 5.58% on a $12,765 allowance, and Nevada, which taxes no wages. The assumptions are a single filer, bi-weekly pay, no dependents and no pre-tax deductions.
| Salary | Colorado | Kansas | Nevada |
|---|---|---|---|
| $52,000 | $1,580 | $2,102 | $0 |
| $100,000 | $3,692 | $4,780 | $0 |
| $150,000 | $5,892 | $7,570 | $0 |
At $52,000 Colorado takes $1,579.60 against Kansas's $2,101.91, a difference of $522.31. Colorado wins on both counts at once — a lower rate and a larger allowance — and because both states apply a fixed subtraction the gap widens in a straight line: $1,088.71 at $100,000 and $1,678.71 at $150,000.
The allowance comparison is the more interesting half. Colorado's $16,100 comes from the federal standard deduction; Kansas's $12,765 is a $3,605 standard deduction plus a $9,160 personal exemption. Kansas's number is fixed in statute and not indexed, while Colorado's moves every year with the federal figure. On the same salary the two states are already $3,335 apart on the base before any rate is applied, and that distance grows annually.
Against Nevada there is no crossover at any salary, since Nevada taxes no wages at all. The difference is the whole Colorado line: $1,580 at $52,000 and $5,892 at $150,000. Colorado's counter-argument is not on a paycheck: the state relies on a local sales tax and a property tax, and neither appears on a stub. This page does not try to price them in.
Colorado take-home pay by salary
The table below fixes one set of assumptions — single filer, bi-weekly pay, no dependents, no pre-tax deductions — so the rows are comparable down the column. The last four rows convert an hourly rate at 40 hours a week into the annual salary it represents.
Colorado's state rate starts at 2.63% on $40,000, reaches 3.04% at $52,000 and 3.69% at $100,000, then approaches 4.16% at $300,000. The shortfall from 4.4% is the federal standard deduction, and because that deduction is indexed it grows every year — which means Colorado's state rate climbs toward 4.4% more slowly than the same curve would in a state with a fixed allowance. On $52,000 the Colorado line is $60.75 a check, which is smaller than the Social Security line of $124.00 and smaller than the federal income tax line of $156.15: of the four deductions on the stub, the state's is the smallest.
Read the net per year column as the amount that reaches a bank account across twelve months. If you are paid hourly, the calculator multiplies the rate you enter by the hours and by 52; overtime and unpaid weeks move the annual figure, and the annual figure is what both the federal brackets and Colorado's 4.4% are applied to.
| Annual pay | Gross per check | State tax per year | Net per check | Net per year | Total effective rate |
|---|---|---|---|---|---|
| $40,000 | $1,538.46 | $1,052 | $1,279.55 | $33,268 | 16.8% |
| $50,000 | $1,923.08 | $1,492 | $1,571.67 | $40,863 | 18.3% |
| $60,000 | $2,307.69 | $1,932 | $1,863.78 | $48,458 | 19.2% |
| $75,000 | $2,884.62 | $2,592 | $2,269.27 | $59,001 | 21.3% |

| $250,000 | $9,615.38 | $10,292 | $6,649.63 | $172,890 | 30.8% |
| $300,000 | $11,538.46 | $12,492 | $7,795.58 | $202,685 | 32.4% |
| $15/hr × 40h ($31,200/yr) | $1,200.00 | $664 | $1,022.49 | $26,585 | 14.8% |

| $25/hr × 40h ($52,000/yr) | $2,000.00 | $1,580 | $1,630.09 | $42,382 | 18.5% |
| $30/hr × 40h ($62,400/yr) | $2,400.00 | $2,037 | $1,933.89 | $50,281 | 19.4% |
Filing status and dependents in Colorado
Filing status changes Colorado's line only through the federal standard deduction, because that is the only subtraction in the calculation. A single filer on $52,000 pays $1,579.60. A married couple on the same salary pays $871.20, a difference of $708.40, which is 4.4% of the extra $16,100 of federal deduction the joint return gets.
Head of household gets $24,150 federally, so a single parent on $52,000 pays $1,225.40 — $354.20 less than a single filer with the same salary. That is a larger state-level benefit for a single parent than Georgia gives, even though Colorado has no dependent allowance at all, because the head of household standard deduction is doing the work.
Dependents themselves are worth nothing to Colorado directly. Each child raises the federal Child Tax Credit and may change the filing status, and both of those change federal taxable income, which Colorado then taxes at 4.4%. A single filer with two children on $52,000 still pays $1,579.60 to Colorado, exactly as a single filer with none. Married filing separately takes the $16,100 separate-return deduction and half the federal bracket width, which is usually the worst of the four statuses overall.
Assumptions and sources
Ruleset 2026.1, verified 2026-10-31. Federal brackets and the standard deduction come from IRS Rev. Proc. 2025-32 (§4.01 and §4.14). Social Security and Medicare rates, the $184,500 wage base and the 0.9% additional Medicare threshold come from IRS Publication 15 (2026), Circular E. The Child Tax Credit amounts are the 2026 figures published by the IRS.
Colorado's rate is 4.4% for 2026 and is applied to federal taxable income, so the standard deduction used here is the federal one: $16,100 single, $32,200 joint, $16,100 married filing separately and $24,150 head of household. Colorado allows no personal or dependent exemption, and no phase-out applies at any income level.
Not modelled: the Colorado earned income tax credit, the family affordability credit, the child care contribution credit, the alternative minimum tax, the credit for taxes paid to another state, wage garnishments, union dues, post-tax deductions, bonuses withheld at supplemental rates and mid-year pay changes.

Frequently asked questions
Does Colorado have a state income tax?
Yes, at a flat 4.4% for 2026, applied to federal taxable income rather than to a Colorado-specific base.
What is Colorado's standard deduction?
It is the federal standard deduction: $16,100 for a single filer, $32,200 joint, $16,100 married filing separately and $24,150 head of household. Colorado does not publish a separate figure.
Does Colorado give an exemption for dependents?
No. Colorado has no personal exemption and no dependent exemption. Children affect the Colorado line only through the federal return — the Child Tax Credit and the filing status change federal taxable income, and Colorado taxes 4.4% of that.
How much is taken out of a paycheck in Colorado?
On $52,000 paid bi-weekly, $369.90 comes out of a $2,000 check: $156.15 of federal income tax, $124.00 of Social Security, $29.00 of Medicare and $60.75 of Colorado income tax. That leaves $1,630.09, or 81.5 cents of every dollar.
How much is a $100,000 salary in Colorado after tax?
$2,903.40 per bi-weekly check, or $75,488.40 across the year, for a single filer with no dependents and no pre-tax deductions. Colorado takes $3,691.60 of that, which is 4.4% of $83,900.
Why does a 401(k) contribution save more in Colorado?
Because Colorado taxes federal taxable income, so a pre-tax contribution reduces both bases. A 6% deferral on $52,000 saves $374.40 federally and another $137.28 in Colorado, where a state with its own base might save nothing on the state side.
Does Colorado have local income taxes?
No. No county or city in Colorado levies an income tax or a payroll tax on wages, and the state has no disability insurance program and no paid family leave premium. A Colorado stub carries one state line.
Is Colorado cheaper than Kansas?
Yes, at every salary, for a single filer. The 4.4% rate and the federal $16,100 deduction beat Kansas's 5.2%/5.58% brackets and $12,765 allowance by $522.31 on $52,000 and $1,678.71 on $150,000.
Can the Colorado rate change during the year?
It can. Colorado's TABOR amendment caps revenue growth, and in 2022 part of the surplus was refunded through a temporary reduction in the income tax rate rather than a cheque. A change in the withholding table does not always mean the Legislature passed a rate bill.
Does Colorado tax retirement income?
Colorado starts from federal taxable income, so retirement income that is excluded federally is excluded in Colorado too. The state also allows a subtraction for certain pension and annuity income for filers over 55, which this calculator does not model.
