Colorado’s child support law was rewritten by HB 25-1159, taking effect March 1, 2026, and consolidated into a single unified worksheet under C.R.S. § 14-10-115. Rather than the older step-based parenting-time adjustments, the new formula applies a continuous credit that scales smoothly with overnights, and it uses a four-tier system for low-income cases. The schedule behind this calculator runs to $40,000 in combined monthly income and was extracted directly from the enrolled bill.
