Complaint filed against federal government for not refunding tax
Since 2007, a tax preparer will be liable for errors committed on any return. This is because the Internal Revenue Code (IRC) §6694 was modified–broadened, really–replacing “an income tax return preparer” with “a tax return preparer.”
If the appeals officer agrees with the IRS, you have the option of challenging the IRS in court. If you choose to pursue the issue in court, you can pay the amount of tax in dispute and file the appropriate documentation in a U.S. District Court or the Court of Federal Claims for a refund.
To report a tax return preparer for improper tax preparation practices, complete and send Form 14157, Complaint: Tax Return Preparer (PDF) with all supporting documentation to the IRS. The form and documentation can be faxed or mailed, but please do not do both.
Report abusive tax preparers to the IRS.
If you suspect a return preparer filed or changed the return without your consent, you should also file Form 14157-A, Return Preparer Fraud or Misconduct Affidavit. You can get these forms at IRS.gov or by calling 800-TAX-FORM (800-829-3676).
