Your tax refund may be delayed by several months next year because Congress waited until the last second to pass a bill temporarily shelving the Alternative Minimum Tax. The AMT was enacted to make sure the rich couldn't use deductions to avoid paying taxes entirely. However, it was never indexed for inflation, so it's starting to hit the middle class. The delay means no new families will have to pay the AMT this time around, but the IRS may not have the proper forms ready in time for February filing because it took so long to get done. A permanent fix could cost the government $800 million in tax revenue, forcing tax hikes elsewhere or massive spending cuts.
