When and How Was Greenback Founded?

Greenback Expat Tax Services was founded in 2009 by American expats Carrie and David McKeegan. While living and working in the UK, they discovered that filing US taxes from abroad was confusing, time-consuming, and expensive. Determined to make life easier for fellow expats, they built a firm that combines world-class expertise with a customer-first mindset.

Our mission—then and now: Make US expat tax preparation easy, accurate, and stress-free.
