Child support in Plano: how it is calculated
Child support in Plano is set by Texas's statewide guidelines — Collin County courts apply the same table as every other county. Here is the calculation, with the statute it comes from.
Where a Plano case goes
A Plano case is filed in the Texas court for Collin County, which applies the state guideline below. Local practice affects timing and paperwork, not the guideline amount. Plano has about 293,286 residents (Census Bureau, 2024 estimate).

Does Plano have its own rule?
No. Tex. Fam. Code §§ 154.125–154.129 applies across Texas, so a case from Plano is decided by the same numbers as one filed anywhere else in the state. What changes locally is the courthouse, the clerk's procedure and how long the docket takes — not the amount.
What the statute says
Tex. Fam. Code §§ 154.125–154.129 — Texas child support guidelines (percentage of net resources). Percentages apply to 'net resources' — income after taxes, Social Security, and the child's health-insurance cost. The cap on net resources rose to $11,700/month on September 1, 2025 (from $9,200). Percentages step down when the payer also supports children in other households (§ 154.129).
