1. Making math errors

When you file taxes, you shouldn’t make any errors, and by errors, I’m referring to the times you accidently write a 3 instead of an 8. Don’t forget to write down every number. Of course, you can make mistakes, but make sure you read everything twice before sending it. Even if this was unintentional, you’ll be fined accordingly.

If your math skills are a little bit rusty, you can always check out Turbotax or Taxact, one of the two best software packages that will help you get through the tax season with no further headaches. And if those are not enough, don’t be shy about asking for help. Not everybody is an expert when it comes to calculations! Make sure you do everything to avoid fines or a spontaneous audit.
