The last thing most of us want to think  of in this economy is an unexpected tax bill. However, as Sandra Block  of USA Today explains, financial hardships can often result in a tax  bill instead of a refund. Block explained a few situations that can  lead to owing taxes in this new article. You can find a few of her examples  below.
Taxes on unemployment benefits. Millions  of Americans who have been out of work for months are relying on unemployment  benefits to put food on the table. In November, Congress extended benefits  by up to 20 weeks for workers in states with high jobless rates.
 
But what many people may not realize  is that some of those benefits are taxable. The economic stimulus package  enacted last year excluded the first $2,400 of unemployment benefits  from 2009 gross income. For unemployed married couples, each spouse  is eligible to exclude up to $2,400 in benefits.
Taxpayers who receive unemployment benefits  should receive Form 1099-G, which shows the amount of benefits you received  for the year. You should report unemployment compensation that exceeds  $2,400 on line 19 of Form 1040, line 13 of Form 1040A, or line 3 of  Form 1040EZ.
