Informational estimate, not an official OAG calculation, legal advice, or a court order. Uses Texas OAG monthly calculator chart parameters (2026 tax year), including the single-filer standard deduction. The self-employment entry is treated as net business profit after ordinary business expenses; other recurring income is treated as federally taxable without payroll tax. The form does not collect every possible net-resource deduction, including qualifying child health or dental insurance costs and union dues; other case-specific facts can also change the court's amount. Possession type does not trigger an automatic reduction.
When net resources are below $1,000 per month, Texas uses the separate low-resource guideline table. Amounts above the $11,700 cap may receive additional case-specific consideration under Texas Family Code §154.126; this estimate applies guidelines only up to that cap.

How Texas calculates child support
Texas uses a net resources method under Family Code §154. The OAG's current calculator uses 2026 tax-chart parameters. This estimate subtracts estimated federal income, Social Security, and Medicare taxes, applies the $11,700/month cap, then applies the guideline percentage. These percentages apply when net resources are at least $1,000 per month:
1 child — 20%
2 children — 25%
3 children — 30%
4 children — 35%
5+ children — 40%
For net resources below $1,000 per month, the OAG calculator uses a special reduced guideline table. If the obligor has other children, the multiple-family adjustment under §154.129 changes the percentage. This form counts “6 or more” children before the court as 6 and “5 or more” other children as 5 for that estimate. It does not include all possible deductions, such as qualifying child health or dental insurance costs and union dues. See the Texas Family Code, Chapter 154 and the Texas OAG monthly calculator.
