No one wants to get audited on their taxes. But making some mistakes can almost guarantee that your tax return will get extra attention from the IRS.

In the following video, Dan Caplinger, The Motley Fool's director of investment planning, talks about the one thing you need to be sure you do on your taxes: match up the figures on your return to those that get reported directly to the IRS. Dan notes that everything from wage income on W-2s to investment and other income on 1099s goes directly into IRS computers, and if your return fails to match up with those records, it can raise a red flag that could cost you money in interest and penalties. He also recommends checking tax withholding and other figures to ensure you don't slip up with math errors that could get you audited.
