The IRS employs fewer investigative agents than it did 50 years ago. As taxes grow more complex and fewer agents exist to investigate claims, the probability that you'll be investigated for tax fraud or tax evasion is low.
Though not likely, if you're in an income bracket that warrants further scrutiny of your returns, it could. If you're caught on the wrong side of the IRS, you could end up losing all your important assets and face serious jail time.
Do you wonder whether the IRS is investigating you for tax fraud? There are signals to look for. Read on to learn more about them.
