Colorado Child Support for 1 Kid: Exact 2026 Calculation

By Alex Kumar · January 6, 2026

Why This Question Matters More Than Ever Right Now

If you’re asking how much is child support for 1 kid in Colorado, you’re likely standing at a pivotal, emotionally charged moment — whether you’re preparing for a divorce filing, negotiating a parenting plan, or recalculating after a job change or custody adjustment. Colorado’s child support system isn’t based on gut feeling or courtroom discretion alone; it’s governed by precise statutory guidelines (C.R.S. § 14-10-115) that prioritize the child’s consistent standard of living — not parental blame. Yet nearly 68% of self-represented litigants in Colorado family courts overestimate or underestimate their obligation by 30% or more (2023 Colorado Judicial Branch Self-Represented Litigant Survey), often because they miss critical deductions or misapply the income-sharing model. Getting this right isn’t just about compliance — it’s about stability for your child, fairness between parents, and avoiding costly enforcement actions down the line.

How Colorado Calculates Child Support: It’s Not Just ‘X% of Pay’

Unlike states that use flat percentages (e.g., “20% of gross income”), Colorado uses an income shares model — meaning both parents’ combined adjusted gross incomes determine the total child support obligation, which is then divided proportionally based on each parent’s share of that combined income. For one child, the baseline economic table sets the total monthly amount needed — but that number shifts dramatically based on actual circumstances.

Here’s the real-world flow:

Step 1: Determine Adjusted Gross Income (AGI) — Not take-home pay. Colorado includes wages, bonuses, commissions, rental income, self-employment net profit, disability benefits, and even certain retirement distributions. But it also allows specific, court-approved deductions: mandatory union dues, required retirement contributions (e.g., PERA), and prior court-ordered child support for other children.
Step 2: Combine Both Parents’ AGIs — Even if only one parent has physical custody, both incomes are factored in. This is where many people get tripped up: the non-custodial parent doesn’t pay a fixed % — they pay their proportional share of the total need.
Step 3: Find the Base Obligation Using the State’s Economic Table — Updated annually (2024 table effective Jan 1, 2024), this table shows the total monthly support needed for 1 child across combined monthly incomes from $0–$30,000+. For example, at a combined AGI of $6,000/month, the table says the total child support need is $1,072/month for one child.
Step 4: Apply Adjustments — This is where precision matters. You subtract costs *already paid* by either parent: health insurance premiums for the child, work-related childcare, and extraordinary medical expenses (with documentation). Then, if parenting time exceeds 92 overnights per year for the non-custodial parent, the base amount is reduced using a sliding scale — not a flat discount.

Let’s ground this with a case study: Maria ($4,200/mo AGI) and James ($3,800/mo AGI) have one 8-year-old daughter. They share parenting time 120 overnights/year. Maria pays $185/mo for her daughter’s health insurance; James pays $320/mo for after-school care. Their combined AGI = $8,000/mo. Per the 2024 table, the base obligation for 1 child is $1,298/mo. Maria’s income share is 52.5% ($4,200 ÷ $8,000); James’s is 47.5%. But before splitting, subtract the verified expenses: $185 + $320 = $505. So adjusted base = $1,298 − $505 = $793. Then apply the parenting time adjustment: 120 overnights = ~17% reduction (per CJD 19-01 guidelines), so $793 × 0.17 = $135 reduction → $658. James (47.5% share) owes $313/mo — not the $617 he’d owe under a simple 47.5% of $1,298. That’s a $304 difference — significant for budgeting.

What Counts as “Income” — And What Doesn’t (With Real Examples)

Colorado law defines income broadly — but also carves out important exclusions. According to Judge Lisa D. Haight, Chief Judge of Colorado’s Fourth Judicial District and co-author of the Colorado Family Law Practice Manual, “Courts routinely reject arguments that ‘side hustle’ cash payments or cryptocurrency gains are ‘not real income’ — if it’s recurring and accessible, it’s likely includable.” Here’s what’s consistently treated as income:

Wages, salaries, commissions, overtime, tips, and bonuses (including annual bonuses prorated monthly)
Rental income (net of documented mortgage interest, property taxes, insurance, and maintenance)
Self-employment income (gross receipts minus ordinary/necessary business expenses — verified via tax returns and P&L statements)
Unemployment benefits, workers’ comp, Social Security Disability (SSDI), and VA disability (but not SSI)
Trust distributions and annuity payments

And here’s what’s typically excluded — unless used to reduce personal living expenses:

Public assistance (TANF, SNAP, housing vouchers)
Child support received for other children
Inheritances or one-time gifts (unless regularly deposited into joint accounts and used for household expenses)
Imputed income from assets (e.g., a $500k investment portfolio generating minimal dividends) — only if a parent is voluntarily unemployed/underemployed

A key nuance: If a parent quits a $90,000/year job to start a risky business earning $2,500/month, Colorado courts will likely “impute” income at $7,500/month (the prior salary) — especially if no credible business plan or early traction exists. As noted in the 2022 Colorado Court of Appeals decision In re: Marriage of Smith, “Voluntary underemployment cannot shield a parent from their financial duty to the child.”

The Shared Custody Effect: Why 92+ Overnights Changes Everything

Many assume “joint custody” automatically cuts support in half. Not true in Colorado. The law uses a strict overnight threshold: if the non-custodial parent exercises 92 or more overnights per year (≈25% of the year), the base child support amount is reduced using the Shared Physical Custody Adjustment Formula. But it’s not linear — it’s progressive:

Annual Overnights with Non-Custodial Parent	Reduction Factor Applied to Base Obligation	Example: Base Obligation = $1,200/mo
92–129 overnights	10%	$1,080/mo
130–159 overnights	15%	$1,020/mo
160–189 overnights	20%	$960/mo
190–219 overnights	25%	$900/mo
220+ overnights (≈60%+ time)	30% (plus additional adjustments for direct expense sharing)	$840/mo + split of insurance/childcare

Note: This reduction applies before allocating the adjusted amount by income share. Also, judges may require detailed logs (text confirmations, school sign-in sheets, travel receipts) to verify overnights — anecdotal claims rarely suffice. In Jefferson County, 73% of contested custody cases in 2023 involved disputes over overnight counts, underscoring the need for meticulous recordkeeping.

Real impact: When David (AGI $5,200) and Lena (AGI $4,800) shifted from 70 to 142 overnights for their son, his monthly payment dropped from $542 to $368 — a $174 savings. But Lena’s attorney successfully argued that David’s new schedule meant he now covered 40% of extracurriculars and school lunches — turning the “savings” into a net neutral when accounting for direct expenses.

Health Insurance, Childcare & Extraordinary Expenses: Where Most People Underclaim

These aren’t optional add-ons — they’re mandatory deductions that lower the base obligation. Yet over 41% of pro se filers omit them entirely (Colorado Judicial Branch, 2023 Data Report). Here’s how to claim them correctly:

Health Insurance: Only the portion specifically for the child counts. If your employer plan covers spouse + 1 child for $320/mo, and the child-only rate is $145 (verified via HR letter or insurer statement), only $145 is deductible. You must provide proof — a redacted paystub or insurer invoice showing the child-specific cost.
Work-Related Childcare: Must be necessary for employment or job search (e.g., licensed daycare, after-school programs, summer camps during work hours). Babysitting by a relative? Only deductible if paid at fair market rate and documented via receipt/bank transfer — not cash “gifts.”
Extraordinary Medical Expenses: Defined as uninsured costs exceeding $250/year per child (e.g., orthodontia, therapy copays, specialized equipment). Requires itemized bills, insurance EOBs, and proof of payment. Cosmetic procedures (e.g., braces for aesthetics only) generally don’t qualify — but orthodontia prescribed for functional issues (bite correction) does, per American Association of Orthodontists guidelines cited in In re: Marriage of Chen (2021).

Bonus tip: If you pay these expenses directly, keep a running log with dates, providers, amounts, and purpose. Colorado courts accept digital logs (Google Sheets, Excel) — just export monthly PDFs and save them chronologically. One Denver father avoided a $2,800 arrears claim by producing 14 months of timestamped Venmo records for his daughter’s weekly speech therapy.

Frequently Asked Questions

Can child support be modified if my income drops significantly?

Yes — but “significantly” means a substantial and continuing change (typically ≥10% change in combined income or a material shift in parenting time). You must file a Motion to Modify with the court — informal agreements aren’t enforceable. Colorado requires updated financial affidavits and proof (e.g., layoff notice, 3+ months of reduced pay stubs). Note: Voluntary quits or demotions usually don’t qualify. As Family Law Attorney Sarah Kim notes, “Courts look at whether the change was within your control — and whether you’ve made diligent efforts to regain comparable income.”

Does Colorado consider college tuition in child support orders?

No — Colorado law explicitly excludes post-secondary education expenses from statutory child support. However, parents can voluntarily agree to contribute to college costs in a separation agreement or parenting plan. If included, those terms are legally binding — but they’re separate from the court-ordered support amount. The Colorado Supreme Court affirmed this in In re: Marriage of Ruckriegle (2007), stating higher education isn’t a “necessity” under the child support statute.

What happens if the other parent refuses to pay court-ordered support?

Colorado uses aggressive enforcement tools: wage garnishment (up to 50% of disposable earnings), tax refund intercepts, driver’s license suspension, passport denial, and contempt of court hearings (which can include jail time for willful nonpayment). The Colorado Child Support Enforcement Unit (CSEU) handles most cases — and in 2023, collected $327 million statewide. Pro tip: Document every missed payment (bank statements, certified mail returns) — CSEU requires a clear payment history to act.

Is child support taxable income for the recipient?

No — and it’s not tax-deductible for the payer. Since the 2019 Tax Cuts and Jobs Act, child support payments are treated as transfers of resources, not income or deductions. This simplifies tax filing but means recipients can’t claim it as income for loan applications or credit building — a common misconception among newly single parents.

Do bonuses or commissions get averaged for child support calculations?

Yes — Colorado courts require a 3-year average for variable income (bonuses, commissions, overtime) unless evidence shows a clear upward or downward trend. For example, if your bonus was $12,000, $15,000, and $18,000 over three years, the average $15,000 is divided by 12 = $1,250/month added to base salary. A sudden $50,000 bonus in Year 4? Courts may exclude it unless it’s part of a consistent pattern, per the Colorado Bar Association’s Family Law Section guidelines.

Common Myths

Myth #1: “The parent with higher income always pays support.”
False. Even if one parent earns significantly more, the income shares model means the lower-earning parent could owe support if they have substantially more parenting time and higher direct expenses. A 2022 Adams County case awarded support *to* a mother earning $38,000/year because the father (earning $112,000) had only 65 overnights and refused to pay for childcare — making her net cost of raising the child higher.

Myth #2: “Child support ends automatically when the child turns 19.”
Not quite. In Colorado, support terminates on the child’s 19th birthday unless the child is still in high school (then it continues until graduation or age 21, whichever comes first) or has a severe mental/physical disability preventing self-support (requires court finding). Always file a Motion to Terminate — don’t assume it stops automatically.
