If You Were a Client of Castro & Company You Should Consult With A Qualified Tax Attorney

On May 24, 2024, John Castro, the managing partner of Castro & Company was convicted of 33 counts of assisting in the preparation of fraudulent tax returns. According to a United States Attorney’s Office Press Release, John Castro marketed himself to clients around the world and claimed to be an “international tax expert” and “federal practitioner.” Between 2017 and 2019, John Castro filed more than 1,900 tax returns on behalf of individuals from all over the world.

John Castro allegedly promised his clients a significantly higher refund than they would receive from other preparers. During trial, John Castro admitted that the positions he took on tax returns were extreme, outlandish, and not supported by the law.

In most cases when a tax professional is convicted of assisting in the preparation of fraudulent tax returns, many of the tax professionals’ former clients face audits by the Internal Revenue Service (“IRS”). An audit can subject the victim-client to assessments of significant additional income tax, penalties, and interest which can cause significant financial hardship.

If you received an opinion letter from Castro & Company and/or if Castro & Company prepared tax returns on your behalf, you should immediately consult with a qualified tax attorney. We have assisted former clients of Castro & Company.
