What is the income shares model?

The income shares model calculates child support based on each parent's income share and the estimated cost of raising the children. Most states use variations of this model.

What counts as 'income' for child support?

Income typically includes wages, salary, bonuses, commissions, self-employment income, rental income, and investment income. Some states also count benefits.

How long does child support last?

Child support typically continues until the child turns 18 (or 19 if still in high school), unless the child is disabled or the parties agree otherwise.

Can child support be modified?

Yes. Significant changes in income or custody can justify modification. Either parent can petition the court.

Is child support deductible?

Child support is NOT tax-deductible for the payor, and NOT taxable income for the recipient (unlike alimony).
