Tax season is underway and that means an uptick in tax-related scams. One particularly pernicious form of fraud is tax identity theft. Tax-related identity theft happens when someone uses sensitive personal information (like your Social Security number) and files a fraudulent tax return in your name to collect a refund. According to recent statistics, scammers filed over 5 million returns in 2013 using stolen information, costing the IRS $5.8 billion in fraudulent refunds.
