Profile bio

About Stefan Thomas

Tax director with extensive experience with US federal corporate tax compliance, consulting, and ASC 740 across a wide range of industries and with companies ranging from middle market to large multinational organizations.The first ~10 years of my career were spent at Deloitte where I mainly focused on large, multinational corporate tax engagements out of the Chicago office. I worked extensively on corporate tax returns, ASC 740 consulting, tax provision preparation and audits, subchapter C issues (i.e. 382 considerations, reorganizations, cancellation of indebtedness, worthless stock deductions, etc.) and other miscellaneous consulting. For my last ~4 years, I was also a leader in the corporate tax group when it came to the development of the professionals in the group as I led efforts to organize, develop, and lead CPE and other learning sessions for professionals from interns to partners.More recently, I've been involved in the rapid expansion and development of the tax team at Filtration Group with a focus on the global tax provision process and domestic tax compliance. My first few years have been focused on completely revamping the year-end close process and creating from scratch a new quarterly provision process. I've also led efforts to bring more of the overall tax compliance process in-house from what was previously a fully outsourced model.

Listed skills include Auditing, Business Ethics, Expatriate Tax, Powerpoint, and 48 others.
