Connecticut’s current child support guidelines took effect July 1, 2015, under Regs. Conn. State Agencies § 46b-215a-2c, and run on combined net weekly income through a 396-row schedule. The regulation also carves out a low-income obligor area with its own treatment, plus percentage-based contribution rules for child care and unreimbursed medical costs. A revised edition of the guidelines is scheduled to take effect August 1, 2026, and this calculator will move to it once it’s live.

Update history
- — The Judicial Branch has published the official booklet for the revised guidelines (effective August 1, 2026). Every row of the calculator's schedule was re-verified against the booklet — all values match — and the booklet's explanatory preamble confirms the two low-income rules this calculator applies: no support obligation below $150 of net weekly income, and the low-income shaded area for one child ending at $470. The sources cited under the calculator now link to the new booklet.
- — Connecticut's revised Child Support and Arrearage Guidelines (effective August 1, 2026) are now built in. The calculator asks whether the order is entered before or on/after August 1 and applies the right edition: the new schedule runs from $150 to $6,000 of combined net weekly income (previously $50 to $4,000), the low-income shaded areas moved, and mandatory Paid Family & Medical Leave contributions are now deducted when the calculator estimates net income. Figures were transcribed and cross-checked from the officially adopted regulation (Secretary of the State file no. 6462).
- — Connecticut went live on the 2015 edition of the Child Support Guidelines, with the full combined-net-weekly-income schedule, the low-income obligor area, and the child-care/medical contribution percentages. A revised guideline edition takes effect 2026-08-01 — this calculator will be updated when it does.
