Most parents dealing with a separation or dissolution of marriage proceedings quickly encounter a system built around one central question: what financial support does the child need, and who pays it? Under Colorado law, child support is not discretionary. Both parents are legally obligated to support their child in proportion to their respective incomes, regardless of marital status. Understanding how that obligation is calculated — and what happens when circumstances change — is where to start.
Colorado governs child support through C.R.S. § 14-10-115, which establishes the Income Shares Model as the mandatory calculation framework. This statute, along with the Colorado Child Support Guidelines periodically updated by the Colorado Child Support Commission, defines which income sources count, what adjustments are allowed, and when a court may depart from the standard formula. Significant updates to the guidelines took effect March 1, 2026, under House Bill 25-1159, and apply to all orders entered or modified on or after that date.
Colorado's Legal Framework for Child Support
The primary statute governing child support in Colorado is C.R.S. § 14-10-115. It establishes mandatory calculation worksheets, defines which income sources are included, identifies allowable adjustments, and sets out when courts may deviate from the guideline amount. Child support cases are handled in the district courts of each county and may arise in several contexts:
- As part of a dissolution of marriage proceeding
- As part of a legal separation
- Within an Allocation of Parental Responsibilities (APR) case
- As a standalone action through Colorado Child Support Services (CSS), an agency within the Colorado Department of Human Services
Before a support order can be entered against a legal father, legal paternity establishment is a prerequisite before child support can be ordered. The Drake Law Firm, PC handles paternity matters as part of its family law practice.
Statutory Definitions of Income
Colorado defines gross income broadly under C.R.S. § 14-10-115(5)(a). Includable income sources encompass wages, salaries, commissions, bonuses, dividends, severance pay, pensions, interest, trust income, Social Security benefits (including disability), workers’ compensation, unemployment insurance, and income from self-employment or operation of a business. Non-recurring or extraordinary income — such as a one-time capital gain — may be treated differently by the court depending on whether it reflects the parent’s ongoing financial capacity.
Income imputation rules apply when a parent is voluntarily unemployed or underemployed. In these situations, the court may attribute income based on the parent’s historical earnings, occupational qualifications, and the prevailing job market.
Certain items are excluded from the gross income calculation, including means-tested public assistance (such as TANF and SSI), child support received for children from other relationships, and income of the parent’s new spouse or partner.

How Child Support Is Calculated: The Income Shares Model
Colorado uses the Income Shares Model, which is based on the principle that a child should receive the same proportion of parental income as if the parents lived together. The calculation follows a structured worksheet process using the state’s official Child Support Schedule — a table of presumed combined support obligations based on combined adjusted gross income and number of children.
Step 1 — Determine Each Parent’s Gross Monthly Income
The court starts with each parent’s gross monthly income from all sources. For W-2 employees this is straightforward. For self-employed parents, net business income after ordinary and necessary business expenses (but before personal tax deductions) is used. For parents with variable income, courts often average the prior 12 to 36 months of earnings.
Step 2 — Calculate Combined Adjusted Gross Income
The two parents’ gross incomes are added together to arrive at the Combined Adjusted Gross Income (CAGI). Adjustments may include amounts paid for health insurance premiums for the child and child support obligations for children from prior relationships.
Step 3 — Look Up the Basic Child Support Obligation
The CAGI and the number of children are entered into the Colorado Child Support Schedule to determine the Basic Child Support Obligation (BCSO). This schedule is codified in C.R.S. § 14-10-115(7)(b) and reflects estimated expenditures on children at various income levels based on economic research. The 2026 updated schedule covers combined monthly adjusted gross incomes of up to $40,000 — increased from the prior $30,000 cap — and reflects current costs of raising a child based on the Betson-Rothbarth Study and 2023 Bureau of Labor Statistics data. For combined incomes above $40,000, courts retain discretion in determining the appropriate amount.
Step 4 — Add Work-Related Child Care and Health Insurance
Work-related child care costs and the cost of the child’s health insurance premium are added to the BCSO to produce the Total Child Support Obligation. The health insurance figure used is the cost of the child’s portion of the premium only — not the total family premium. Coverage through public programs such as Medicaid or CHP+ is also accounted for under this step. These are actual, documented costs — not estimates.
Step 5 — Apportion Between Parents
Each parent’s share of the Total Child Support Obligation is proportional to their contribution to the CAGI. For example, if Parent A earns 60% of the combined income, Parent A is responsible for 60% of the obligation. The residential parent is presumed to spend their share directly; the non-residential parent’s share is the payment amount.
Parenting Time and Child Support
For orders entered or modified on or after March 1, 2026, Colorado has eliminated the previous “93-overnight cliff” under the updated C.R.S. § 14-10-115(8). Prior law only recognized shared parenting time for child support purposes once a parent reached 93 or more overnights per year — meaning a parent with 90 overnights received the same credit as a parent with zero. That threshold no longer applies.
Under the 2026 framework, every overnight is formally recognized through a graduated Parenting Time Table. A parent receives incremental credit for parenting time expenses starting from the first overnight, scaled proportionally across the full range of parenting time. The prior dual-worksheet structure (Worksheet A for sole custody, Worksheet B for shared custody) has been replaced by a unified calculation: the basic support obligation is drawn from the standard schedule, allocated between parents in proportion to their adjusted gross incomes, and then each parent receives a parenting time credit based on their share of overnights as listed in the Parenting Time Table. The annual overnight count comes directly from the parenting schedule established in a parenting plan or custody order, making accurate documentation of that schedule essential.
At equal parenting time (182 or more overnights each), the parenting time credit is maximized, though a support obligation may still exist if there is a meaningful income disparity between the parents.
For very low-income parents, the Self-Support Reserve (SSR) and Low-Income Adjustment provisions may affect the final obligation. The SSR is calculated at 29 hours per week at the state minimum wage multiplied by 50 weeks and divided by 12 — a figure that adjusts as Colorado’s minimum wage changes. Parents whose income falls between $650 per month and the SSR are subject to a revised low-income schedule, and those whose income exceeds the SSR but remains near minimum wage have their total support obligation capped as a percentage of income.
Deviation from the Guidelines
Under C.R.S. § 14-10-115(3)(b), a court may deviate from the guideline amount if application of the formula would be inequitable, unjust, or inappropriate in a specific case. Grounds for deviation include:
- Extraordinary medical needs of the child
- Educational costs of the child
- Special needs of the child
- Financial resources of the child
- Travel expenses for parenting time
Any deviation must be supported by written findings stating the amount that would have been ordered under the guidelines and why deviation serves the child’s best interests.
Establishing a Child Support Order in Colorado
Through Divorce or Allocation of Parental Responsibilities
When parents divorce or legal separation involves minor children, the court will enter a child support order as part of the final decree. The parties must file a completed Child Support Worksheet along with sworn financial disclosures. Colorado Rule of Civil Procedure 16.2 requires both parties to exchange mandatory financial disclosures, including three years of tax returns, two months of pay stubs, and documentation of all assets and debts. Working with Colorado child support attorneys during this stage helps ensure disclosures are complete and the worksheet accurately reflects each parent’s financial circumstances.
Through Colorado Child Support Services
Colorado Child Support Services (CSS), administered at the county level through local Child Support Units, provides services to establish, collect, and enforce child support orders. Services are available to any parent regardless of income and are required for families receiving TANF benefits. CSS can establish paternity, locate the other parent, establish a support order through the courts or through an administrative process, and collect payments through the Colorado Family Support Registry (CFSR).
Temporary Orders
During a pending divorce or APR case, either party may request temporary child support via a motion and financial affidavit. Temporary orders remain in effect until the court enters a final order at the permanent hearing. The temporary amount is calculated using the same guideline formula.
Payment, Collection, and the Colorado Family Support Registry
All child support payments ordered by Colorado courts are made through the Colorado Family Support Registry (CFSR), administered by the Colorado Department of Human Services. Direct payments between parents are not recognized as satisfying a court-ordered support obligation unless the order specifically authorizes them — paying directly to the other parent risks having those payments treated as gifts in any subsequent enforcement action.
Income Withholding Orders (IWO) are issued automatically in most cases under C.R.S. § 14-14-111.5. The IWO directs the paying parent’s employer to deduct support from wages and remit directly to the CFSR. IWOs can also be served on unemployment benefits and some other income sources. Parents who are self-employed or have variable income may be required to make direct payments to the CFSR on a scheduled basis.
Enforcement of Child Support in Colorado
When a parent fails to pay court-ordered child support, Colorado law provides a broad array of enforcement tools. Enforcement actions can be initiated by the receiving parent, by their attorney, or by Colorado Child Support Services.
Administrative Enforcement Remedies
C.R.S. § 26-13-122 and related statutes authorize CSS to take the following administrative actions without a court hearing:
- License suspension: driver’s licenses, professional licenses, recreational licenses (hunting, fishing), and business licenses
- Tax intercept: federal and Colorado state income tax refunds
- Credit bureau reporting: delinquent support reported to consumer credit agencies once arrears exceed a threshold
- Bank account seizure (FIDM): CSS can freeze and seize funds in bank accounts through the Financial Institution Data Match program
- Lottery and gambling intercept: winnings above the statutory threshold are intercepted
- Passport denial: the federal Office of Child Support Enforcement (OCSE) denies or revokes passports when arrears exceed $2,500
Judicial Enforcement Remedies
A party or CSS may also seek judicial enforcement through a motion for contempt of court (C.R.C.P. 107). If the court finds a parent in contempt for willful non-payment, remedies include fines, a remedial or punitive jail sentence, and entry of a judgment for arrears. Judgments for unpaid child support bear interest at the statutory rate. In egregious cases, criminal prosecution under C.R.S. § 14-14-104 (criminal nonsupport) may apply.
Interstate Enforcement — UIFSA
Colorado has adopted the Uniform Interstate Family Support Act (UIFSA), codified at C.R.S. § 14-5-101 et seq. Under UIFSA, a Colorado order can be registered and enforced in any other state, and orders from other states can be registered in Colorado. The issuing state retains continuing exclusive jurisdiction over the support order as long as a party or the child remains in that state.
Modifying Child Support in Colorado
A child support order may be modified when there has been a substantial and continuing change of circumstances that results in at least a 10% change in the monthly support amount under C.R.S. § 14-10-122(1)(a). This 10% threshold is the operative standard — a court will not grant a modification unless the recalculated amount reflects that change. The passage of time alone is generally not sufficient grounds for a judicial modification without a corresponding shift in financial circumstances or parenting time.
For cases managed by Colorado Child Support Services, CSS conducts an administrative review every three years. However, even in those reviews, a modification will only be entered if the recalculation produces at least a 10% change in the obligation amount.
What Constitutes a Substantial Change
Examples of changes that may support a modification petition include:
- Significant increase or decrease in either parent’s income (including job loss, promotion, or career change)
- A change in the number of overnights the child spends with each parent
- The child gaining or losing health insurance coverage through a parent’s employer
- Substantial changes in work-related child care costs
- The child developing significant medical or educational needs not previously ordered • Emancipation of one child in a multi-child order, requiring recalculation for remaining children
The Modification Process
The requesting parent files a Motion to Modify Child Support along with an updated Child Support Worksheet and updated financial disclosures. If the parties agree on the new amount, a Stipulation and Proposed Order can be submitted for the court’s approval. If not, the matter proceeds to a hearing where both parties present current financial information.
The modification is effective from the date of filing of the motion — not the date of the hearing — so prompt filing is important. Until a court enters a modified order, the original obligation remains in full force. A parent experiencing sudden financial hardship, such as a layoff, should file the modification motion immediately rather than waiting to see if circumstances improve.
Duration and Termination of Child Support in Colorado
Under C.R.S. § 14-10-115(13), child support in Colorado terminates by operation of law when the last or only child covered by the order turns 19. No court motion is required for termination in that circumstance. However, if the order covers multiple children and only one reaches age 19, the obligation does not automatically reduce — the paying parent must file a motion to modify so the court can recalculate the amount for the remaining children.
Additional exceptions that may extend support beyond age 19 include:
- The child has not yet graduated from high school at age 19 — support continues until graduation or age 21, whichever occurs first
- The child is mentally or physically disabled — the court may order support beyond age 19 upon a showing of need
- The parties have agreed in writing to extend support for post-secondary education or other purposes — Colorado courts cannot order a parent to pay college expenses over their objection, but such provisions are enforceable as contract terms if voluntarily agreed upon and incorporated into the court order
Support also terminates upon the child’s emancipation before age 19, which may occur through marriage, military enlistment, or a court order.
Tax Considerations
Child support payments are tax-neutral under both federal and Colorado state law. The paying parent may not deduct child support payments, and the receiving parent does not report them as taxable income. For divorce decrees entered after December 31, 2018, Colorado spousal maintenance is also tax-neutral at both the federal and state level under the Tax Cuts and Jobs Act — the payer may not deduct it and the recipient does not report it as income. Both obligations are treated the same way for tax purposes under current law.
By default, the parent with the majority of overnights has the right to claim the child as a dependent for purposes of the Child Tax Credit and Earned Income Tax Credit. However, parents may agree — or the court may order — that the non-residential parent claim the child in alternating years or under other arrangements, formalized through IRS Form 8332.
Child Support and Paternity in Colorado
Before a child support order can be entered against a legal father, Colorado paternity law governs how legal fatherhood is determined. In Colorado, paternity is established in one of three ways:
- The parents are married at the time of birth (the marital presumption under C.R.S. § 19-4-105)
- Both parents sign a Voluntary Acknowledgment of Paternity (VAP) at the hospital or through the Colorado Vital Records office
- A court or administrative order following genetic testing adjudicates paternity
Once legal paternity determination is complete, either parent may seek a child support order. The Colorado Child Support Services program provides administrative paternity establishment services at no cost to the applicant.
Frequently Asked Questions About Child Support
Is child support taxable in Colorado?
No, child support is tax-neutral. The parent receiving the payments does not report them as taxable income, and the parent paying support cannot claim them as a tax deduction on their state or federal return.
Does child support count as income?
For tax purposes, child support does not count as income. However, lenders may consider it as income when you apply for a mortgage or car loan, and state agencies may count it when determining eligibility for certain public assistance programs.
How is child support calculated in Colorado?
Colorado uses the Income Shares Model, which estimates the amount parents would have spent on the child if they were still together. The court inputs both parents’ gross monthly incomes, the number of overnight visits, and expenses like health insurance and childcare into a statutory formula to determine the final amount.
How to apply for child support?
You can apply directly through the Colorado Child Support Services (CSS) website or your county’s Department of Human Services. Alternatively, if you are going through a divorce or custody case, a Colorado child support lawyer at The Drake Law Firm, PC can file the necessary motions with the court to establish an order as part of your case.
What happens if a parent doesn't pay child support in Colorado?
Colorado takes non-payment seriously, and enforcement measures can include wage garnishment, interception of tax refunds, and suspension of driver’s or professional licenses. In severe cases, a motion for contempt of court may result in fines or jail time for the non-paying parent.
