One way to help you avoid math errors is to file electronically so the calculations are done for you. Bye-bye, No. 2 pencil! So long, calculator!
3. You Didn’t Account for All Your Income
Did you have a side hustle early last year? A freelance design gig for a friend’s business? If so, you’re going to need to account for it, regardless of whether you received a W-2 or 1099 from whomever paid you. That’s because, while there’s an IRS threshold for filing these documents by employers, there’s no similar threshold for claiming the income. Income is income is income. If you made money and don’t report it — and the IRS catches it — it’s going to cost you penalties and interest at best, and open you to a possible audit at worst.
4. You Forgot Deductions or Tax Credit
It's easy to forget these things when you're in a hurry, but they can end up saving you some serious money and are well worth the extra time to figure out if you qualify. So if you're just claiming the standard deductions because you're under the gun, you might want to take a deep breath and check out TurboTax's list of 10 commonly overlooked tax deductions that can keep you from overpaying the tax man.
5. You Filed for an Extension but Didn’t Understand the Rules
Filing for an extension is a great idea if you’re down to the wire and don’t really understand your tax situation. But remember that an extension gives you an extra six months to file your paperwork, but not an extra six months to pay any taxes due. So, if you’re confused, tax pros recommend doing a quick calculation of your taxes, filing for your extension and making any required payment of taxes you think you owe. This will help you avoid penalties and interest once you get your final calculations together.
6. You Didn’t Bother to Request an Extension
You gave up. You shoved, slammed and jammed your return through and now it’s full of mistakes that are going to cost you money by way of penalties or because you’ve left money on the table. It’s a much better idea to file the extension, then get the help you need from a tax professional to ensure you’re not overpaying your taxes.
Whatever you do, make sure you file your taxes. Unpaid taxes can have serious consequences on your personal finances, including your credit scores if they go unpaid long enough.
