If you only remember one point about how child support is calculated in Maine, remember this: Maine uses the Income shares and measures income as gross income. Maine’s guidelines use combined parental income to determine a basic support entitlement from statutory tables, then allocate by income share. Medical support and childcare are addressed in the support worksheets. Procedure, examples, and the opinions below hang off 19-A M.R.S. §§ 2001–2012. Support generally ends when Support generally ends at 18, or upon high-school graduation if later under statutory conditions. Modification: Substantial change in circumstances; guideline recalculation frames most motions.
Deviation from the guidelines
Deviation is permitted when the guideline amount is inequitable, including for extraordinary expenses or nonrecurring income.
When a court departs from the presumptive amount, Maine practice generally requires findings that explain why the guideline figure is unjust or inappropriate and what amount better serves the child's needs. Those findings matter on appeal and in later modification proceedings.
Walking through Maine facts
Use this walkthrough to see which Maine authority does the work at each step.
Two parents in Maine need a presumptive child-support figure and may have facts that justify a departure.
- Measure guideline income as gross income under 19-A M.R.S. §§ 2001–2012.
- Apply the Income shares: Maine’s guidelines use combined parental income to determine a basic support entitlement from statutory tables, then allocate by income share. Medical support and childcare are addressed in the support worksheets.
- Test deviation: Deviation is permitted when the guideline amount is inequitable, including for extraordinary expenses or nonrecurring income.
- If circumstances later change: Substantial change in circumstances; guideline recalculation frames most motions.
The enforceable number is the Maine guideline result under 19-A M.R.S. §§ 2001–2012, plus any deviation findings. Division of Support Enforcement and Recovery uses withholding, intercepts, and contempt.
Modification of child support
Substantial change in circumstances; guideline recalculation frames most motions.
A parent seeking a change typically must show that circumstances after the prior order make the existing award inequitable. Common triggers include job loss, substantial income changes, a new parenting-time schedule, emancipation of a child, or extraordinary medical needs. Retroactivity and temporary relief rules are statute-specific — check 19-A M.R.S. §§ 2001–2012 and local family-division procedures.
Enforcement in Maine
Division of Support Enforcement and Recovery uses withholding, intercepts, and contempt.
Interstate cases often implicate UIFSA. Income withholding, contempt, license suspension, and tax-refund intercept remain core tools nationwide, but the Maine child support agency and clerk of court procedures control day-to-day collection.
When child support ends
In Maine, Support generally ends at 18, or upon high-school graduation if later under statutory conditions. Orders may extend for disability, secondary education, or other statutory grounds where the statute allows. Always read the judgment language — agreed orders sometimes set a different end date or require a notice of emancipation.

Statutory framework and guideline model
Maine's child support system is built around 19-A M.R.S. §§ 2001–2012. Under the income shares, Maine’s guidelines use combined parental income to determine a basic support entitlement from statutory tables, then allocate by income share. Medical support and childcare are addressed in the support worksheets.
Federal law requires every state to maintain presumptive guidelines and to review them at least every four years (42 U.S.C. § 667). Confirm the latest Maine schedule or worksheet before relying on any online calculator.
How child support is calculated in Maine
- Identify each parent's guideline income using gross income as defined in 19-A M.R.S. §§ 2001–2012 and the accompanying worksheets or administrative rules.
- Apply the income shares — whether that means a combined-income schedule, an obligor percentage table, or a Melson-style self-support reserve plus primary obligation.
- Allocate add-ons such as health insurance premiums, unreimbursed medical expenses, and work-related child care according to Maine practice.
- Consider parenting time adjustments where the guidelines or case law authorize a credit or shared-custody formula.
- Test for deviation if a strict guideline result would be unjust or inappropriate on the record.
Online calculators can illustrate ranges, but only the controlling statute, guidelines, and court findings produce an enforceable order.
