How do I file a complaint against a tax preparer?

You can file a complaint against a tax preparer with the IRS by filing Form 14157-A (Tax Return Preparer Fraud or Misconduct Affidavit) and Form 14157 (Complaint: Tax Return Preparer). However, you can only file it if they did one of the following: 1) Filing an individual Form 1040 without your knowledge or consent; 2) Altering your tax return documents; 3) Using the wrong filing status to increase your refund; 4) Making up dependents or exemptions to increase your refund, 5) Creating or omitting income to increase your refund; 6) Making up false deductions, expenses, or credits to increase your refund; or 7) Misdirecting your refund. If your tax preparer did one of these things, mail the 2 forms with your supporting documentation to the IRS. You may also report the tax preparer to the state agency if they're licensed in your state. For instance, you could report a CPA to your state's Board of Accountancy.
