§ How Vermont calculates support
Vermont uses the Income Shares model under 15 V.S.A. §§ 650–670, based on each parent's AVAILABLE income (gross income minus federal/state income taxes, FICA, preexisting child/spousal support, and the child's health insurance premium, using standardized Tax Conversion Tables). The Table of Intact Family Expenditures sets the base by combined available income and children. Sole custody is one parent with >75% overnights; shared custody tiers add a 50% increase — at 25%–<30% overnights a shared-costs table applies, and at 30%+ overnights the obligation is increased by 50% and allocated by income and time. A self-support reserve ($1,596/month as of Feb. 2026) protects low-income obligors. Support ends at 18 or high school graduation.

✦ How to open or modify a case in Vermont
- Apply for services through the Vermont DCF Office of Child Support (OCS); services are free. Use the OCS online calculator or contact OCS.
- Establish parentage if unmarried (voluntary acknowledgment or court-ordered genetic testing).
- Both parents complete an Affidavit of Income and Assets (Form 813) and disclose income; OCS or the court converts gross to available income using the Tax Conversion Tables.
- Use the correct worksheet (sole, split, or shared custody) with the Guideline Table to compute the base, adding health insurance and childcare.
- Obtain an order from Family Court; the guideline amount is a rebuttable presumption and any deviation requires written findings under § 659.
- Request a modification on a substantial change in circumstances (commonly a 10%+ difference in the recalculated guideline amount).
◈ Illustrative examples
Scenario: Parents' combined available monthly income is $5,000 with one child. The NCP earns $3,000 (60%) and the CP earns $2,000 (40%). The CP has primary custody (>75% overnights).
Walk-through: From the Guideline Table, combined available income of $5,000 with one child is $782/month. The NCP pays 60% of the base: 0.60 × $782 = $469/month, plus 60% of add-ons (health insurance and childcare are added and split proportionally).
Takeaway: Vermont splits the guideline base by each parent's percentage of combined available income.
Scenario: Same $5,000 combined available income and one child, but each parent has at least 30% of overnights (shared custody).
Walk-through: Because each parent has 30%+ overnights, the total obligation is increased by 50%: $782 × 1.5 = $1,173, then allocated between the parents based on both income and the amount of time each has the child. A 25%–<30% range instead uses the shared-costs table (also with the 50% increase).
Takeaway: Shared custody raises the total (two homes) by 50%, then allocates it by income and parenting time.
