How Texas calculates support
The Percentage of Income applies a fixed percentage to the NON-CUSTODIAL parent's income, scaled by the number of children. The custodial parent's income generally does not change the base obligation, though courts can deviate.
| Children | Percent of income |
|---|---|
| 1 | 20% |
| 2 | 25% |
| 3 | 30% |
| 4 | 35% |
| 5 | 40% |
Percentage of non-custodial parent's net monthly resources (gross income minus federal/state income taxes, FICA, union dues, and the child's health insurance cost), capped at $11,700/mo net resources (raised from $9,200 effective Sept 1, 2025). Military BAH/BAS is included in gross income per state guidelines.
