Uncle Sam is usually a pretty unforgiving guy, but if you were unemployed in 2011 he might be willing to cut you some slack on your taxes this year. While Uncle Sam will of course want the full amount of taxes you owe at some point in time, you may be eligible to receive extra time to pay your 2011 tax bill without incurring additional failure-to-pay penalties (.5% to 1% of your unpaid taxes for each month up to 25 percent of your unpaid taxes). That could save you as much as $500 per month!
