Form 14157‑A (SP) is the IRS’s official affidavit used to report fraud, misconduct, or other serious issues involving a tax return preparer. The “(SP)” designation indicates the Spanish‑language version of the form, but the same filing requirements apply to all taxpayers.
This form must be submitted together with Form 14157 and any supporting documentation referenced in the instructions. It provides the IRS with detailed information about the alleged misconduct, allowing the agency to investigate and take corrective action.
Instead of downloading the PDF and opening it in a separate editor, you can fill it out directly on our site:

Only file the form when you have concrete evidence or a strong belief that a preparer engaged in fraud, misconduct, or willful non‑compliance. Unsubstantiated claims may delay investigations.
The IRS currently requires a printed, signed copy mailed to the appropriate address. However, you can use the fillable PDF to ensure accuracy before printing.
Attach any IRS notices, correspondence, receipts, or other evidence that supports your claim. Clearly label each attachment.
The content and required information are identical; only the language of the instructions and field labels changes.
Response times vary. The IRS typically acknowledges receipt within 30 days, but investigations can take several months depending on complexity.
Providing false information under penalty of perjury can result in criminal charges, fines, and possible imprisonment.
While not required, a tax professional can help ensure accuracy, especially if the case involves complex issues.
