Tax preparation involves numerous forms and regulations, and people often make mistakes when tackling the process. With the help of an accountant and by knowing some of the most common errors to avoid, here's how you can file your taxes without issues. 

The Most Common Mistakes in Tax Preparation

1. Math Errors

Whether it's an addition error or a complex calculation of the year's expenses, math mistakes are among the most common. The IRS automatically fixes simple errors, but complex ones or too many of them could flag your return for an audit. Double-check all the math with a calculator or tax preparation software, which handles the calculations automatically. 

2. Incorrect Bank Account Information

Those who want their refund quickly can sign up for direct deposit rather than having a check mailed. However, an incorrect digit in the account or routing number will cause delays. Check your bank account information more than once. 

3. Forgetting to Sign

A return is not valid unless signed. If you forget to sign and date the form, it will be sent back to you, which may result in a late filing. If you're married filing jointly, both spouses need to sign and date the return. 

4. Sending the Return to the Wrong Office

Different IRS offices serve varying functions. You can avoid sending your return to the wrong place by filing online. If you must file a paper return, you can find the appropriate office on the IRS website

5. Incorrectly Listing Dependents

Taxpayers who claim dependents must list all names and taxpayer identification numbers. If using a Social Security number, the name must be listed on the return exactly how it is shown on the person's card.
