Brandon Keim

A Certified Tax Law Specialist, CPA, partner at Frazer Ryan Goldberg & Arnold LLP, and former Senior IRS Trial Attorney, Brandon Keim holds an LL.M. in Taxation from Georgetown University Law Center.

Brandon joined Frazer Ryan after serving six successful years as a senior trial attorney with the Internal Revenue Service. At the IRS, he received the Chief Counsel National Award for Superior Achievement in Outstanding Litigation, and he was frequently recognized for his service as a trial attorney (see Case Results).

In 2015, Brandon successfully litigated the first Section 831(b) captive insurance case before the U.S. Tax Court; he litigated a second captive insurance case in 2016. For over four years, he oversaw and advised IRS attorneys and revenue agents auditing captive insurance transactions nationwide. Brandon also acted as an advisor to IRS attorneys on partnership and estate and gift tax matters and was an instructor at a national course designed to train new IRS trial attorneys on all aspects of practice.

Brandon's clients benefit from his knowledge and experience in a broad scope of tax controversies. His services include:

  • defending clients in civil audits by the IRS and state taxing authorities
  • resolving unpaid taxes through collection alternatives, including offers in compromise
  • representing clients in litigation involving Section 831(b) captive insurance; Section 280E cannabis issues; complex corporate, partnership, collection, and estate and gift tax matters; employment tax; property tax; international tax matters, including FBAR penalties; abusive transactions; fraud; and worker classification
  • addressing offshore assets and foreign reporting requirements, including the IRS's voluntary disclosure programs
  • representing clients under criminal investigation, including allegations of tax evasion, failure to disclose foreign assets, and failure to pay employment and income taxes.
