As noted by Sophos, please be careful of tax scams circulating currently:

QUOTE: In the US, To remind taxpayers to be on the lookout for scams ranging from identity theft to return-preparer fraud, the Internal Revenue Service (IRS) on Tuesday posted its Dirty Dozen list of tax scams for 2013. The IRS compiles the list every year. It notes that taxpayers can expect the scams any time of year, but many of the schemes peak now, during filing season.
