Family support is combined child and spousal support. Child support is never taxable or deductible. Under current tax law, neither family nor spousal support are taxable to the recipient or deductible to the payor. Care must be taken in deciding yearly support amounts. Certain step-downs in yearly amounts will trigger the IRS to deny deductibility of older agreements. Financial analysis takes into account these tax issues. In addition, certain levels of family or spousal support may require quarterly estimated income taxes to be filed and paid. My spouse has equity incentives such as stock options, restricted stock benefits, and other employee plans.
