I got a late 1099-MISC form in the mail and already received my return for when I filed in early February 2009 with just my W2's. My question is, should I file for an extension if my amendment will be sent off after the April 15, 2009 deadline? I am trying to avoid the hefty failure-to-file by deadline penalities (.05% interest is much better than 5% interest if I owe the IRS money).
