When I sold my business 2 years ago a large part of the payment was put into an escrow account to cover environmental remediation. I don't have to pay income tax on that amount until I actually receive it when the remediation is done and the account is liquidated. However I do have to pay income tax on the account's income. (at least according to the accountant I used then; but he was an idiot, so he might not have been right.)
In 2007 the account made money and I paid income tax on it. I am told that when I receive money from the account I subtract the amount of income I recognized in 2007 from the final income when figuring capital gains tax. In 2008 it will lose money. Presumably the loss goes on my 2008 income tax return, and I add it back in when the account liquidates. Does that seem right?
