Accountants must keep an eye on the progress of the "fiscal cliff" talks as many key tax provisions are still undecided for 2013. The biggest concern is the alternative minimum tax because the Internal Revenue Service has written its programs assuming the AMT patch will happen. The uncertainty has also upended the typical year-end advice CPAs give clients, which is to delay income. "I think the big priority this year is to stay connected to the news and follow developments over the lame-duck session to try to make final decisions," says Edward Karl, CPA, vice president of taxation at the AICPA.
