California requirements and review scope

FL-150 Income and Expense Declaration; guideline calculation under § 4055. Use California Family Code §§ 4058–4059 to determine the amounts counted for each party.
Wages, dividends, interest, business earnings, and other countable income are added separately for each party. Enter each dollar once; do not repeat business profit as an owner distribution.
General asset balances, loan balances, and household spending are not collected in this support-calculation workflow. Enter countable earnings from assets. A separate court financial affidavit may require additional disclosures.
Business and rental deductions must be expenses allowed for support, which can differ from tax-return deductions. Do not deduct personal living expenses as business expenses.
This worksheet needs state-permitted tax and other deductions. Enter the guideline tax deduction, not take-home pay or every deduction shown on a pay stub. Automatic tax preparation is not provided.
California § 4059 governs net disposable income. Enter allowed tax liability, mandatory retirement/union deductions, permitted insurance and support deductions. The state formula also needs the higher earner’s parenting-time percentage.
Uses California Family Code § 4055 statewide uniform guideline formula operative September 1, 2024.
Inputs must be net monthly disposable income as determined under California Family Code § 4059; this module does not derive taxes, mandatory deductions or add-backs from gross wages.
The high earner parenting-time percentage is the approximate percentage of time the high earner has primary physical responsibility for the children.
If the obligor qualifies for the statutory low-income adjustment, this module reports the permitted range and leaves the final adjustment to the court/computer worksheet.
Health insurance, uninsured health care, child care, add-ons, hardship deductions, default-proceeding assumptions, differing time-share arrangements and deviations require the full California worksheet.

The available formula is a limited base calculation. Full parity with every line of the official worksheet, custody arrangement, tax computation, credit, and discretionary adjustment has not been verified. Review the stated limitations and the official sources.
