C. For purposes of this section, "gross income" means all income from all sources, and shall include, but not be limited to, income from salaries, wages, commissions, royalties, bonuses, dividends, severance pay, pensions, interest, trust income, annuities, capital gains, social security benefits except as listed below, workers' compensation benefits, unemployment insurance benefits, disability insurance benefits, veterans' benefits, spousal support, rental income, gifts, prizes or awards.
If a parent's gross income includes disability insurance benefits, it shall also include any amounts paid to or for the child who is the subject of the order and derived by the child from the parent's entitlement to disability insurance benefits. To the extent that such derivative benefits are included in a parent's gross income, that parent shall be entitled to a credit against his or her ongoing basic child support obligation for any such amounts, and, if the amount of the credit exceeds the parent's basic child support obligations, the credit may be used to reduce arrearages.
Gross income shall be subject to deduction of reasonable business expenses for persons with income from self-employment, a partnership, or a closely held business. "Gross income" shall not include:
1. Benefits from public assistance and social services programs as defined in § 63.2-100;
2. Federal supplemental security income benefits;
3. Child support received; or
4. Income received by the payor from secondary employment income not previously included in "gross income," where the payor obtained the income to discharge a child support arrearage established by a court or administrative order and the payor is paying the arrearage pursuant to the order. "Secondary employment income" includes but is not limited to income from an additional job, from self-employment, or from overtime employment. The cessation of such secondary income upon the payment of the arrearage shall not be the basis for a material change in circumstances upon which a modification of child support may be based.
For purposes of this subsection: (i) spousal support received shall be included in gross income and spousal support paid shall be deducted from gross income when paid pursuant to an order or written agreement and (ii) one-half of any self-employment tax paid shall be deducted from gross income.
Where there is an existing court or administrative order or written agreement relating to the child or children of a party to the proceeding, who are not the child or children who are the subject of the present proceeding, then there is a presumption that there shall be deducted from the gross income of the party subject to such order or written agreement, the amount that the party is actually paying for the support of a child or children pursuant to such order or agreement.
Where a party to the proceeding has a natural or adopted child or children in the party's household or primary physical custody, and the child or children are not the subject of the present proceeding, there is a presumption that there shall be deducted from the gross income of that party the amount as shown on the Schedule of Monthly Basic Child Support Obligations contained in subsection B that represents that party's support obligation based solely on that party's income as being the total income available for the natural or adopted child or children in the party's household or primary physical custody, who are not the subject of the present proceeding. Provided, however, that the existence of a party's financial responsibility for such a child or children shall not of itself constitute a material change in circumstances for modifying a previous order of child support in any modification proceeding. Any adjustment to gross income under this subsection shall not create or reduce a support obligation to an amount which seriously impairs the custodial parent's ability to maintain minimal adequate housing and provide other basic necessities for the child, as determined by the court.
In cases in which retroactive liability for support is being determined, the court or administrative agency may use the gross monthly income of the parties averaged over the period of retroactivity.
