Two months later, after we'd shifted into off-season mode (i.e. after 4/15) she came back again, thoroughly pissed because Rhode Island, which had already cut her a refund check before the amendment showed up, was refusing to send her an additional refund based on the amendment. Basically, their attitude was they'd already paid her refund, and if she wanted more money, that was too fucking bad. Client was adamant that I must have screwed up the amendment somehow. Two other tax pros reviewed it and didn't see any errors. Office head called Rhode Island and got the same line: they'd already paid the refund, they weren't going to pay any more, and fuck your amendment. Come up here and sue us.
Client had, per my advice, bought Peace of Mind coverage because of all the state returns, and filed a claim to get her tax preparation fees -for the original return AND the amendment- back "because Kevin must have done something wrong." Last I heard, Corporate was leaning toward paying the claim despite the objections of both the tax pros who'd handled it in the off-season...but it's not my problem any more.
