The U.S. Internal Revenue Service (IRS) has been authorized to issue a subpoena to MY Safra Bank to obtain customer information of its client, cryptocurrency broker SFOX, according to local U.S. court documents. The IRS wants MY Safra Bank to provide information on SFOX customers who may not have reported their cryptocurrency transactions on their tax returns. MY Safra Bank partnered with SFOX in 2019 to provide SFOX users access to cash deposit bank accounts, and the IRS has identified at least 10 SFOX users who failed to report their cryptocurrency transactions as required by law.
