I sold stock in April of 2008. I was taxed on 100% of the gain in 2008, but received 10% of the proceeds from the sale in 2009. Should the 2009 receipt of funds be included as income in the support calculation for 2009 (even though it is clearly 2008 income and taxed in 2008)?

If you reported the full amount of the gain in '08, then this is not income in '09. But I don't understand why you didn't receive the full amount of proceeds back in April '08 - please clarify. Did you receive a 1099-B form in January that reported the full amount of money you received for the sale of this stock in tax year 2008?

It was stock in a private company. The entire company was sold, and the buyer was entitled to put a 10% holdback in escrow, the release of which was contingent on certain things happening (e.g. that the receivables would be collected). The stockholders elected that the entire amount be taxed in the year of the transaction (including the 10% holdback). The contingencies were met, and the entire holdback was released in 2009. Therefore, none of the amount received in 2009 is taxable. But the question is, does this receipt of cash factor into the computation of child support?
