The company prepares U.S. federal and state returns for Americans living abroad, expats who have moved back to the U.S., and foreign nationals in the U.S. with international tax obligations.

Seventeen Years of Growth

“Growing a business over the past 17 years has required us to adapt to economic uncertainty, rapid technological change, and an evolving global landscape, so it’s a welcome honor to be recognized as one of the 5,000 fastest-growing private companies in America,” said Greenback CEO Mike Wallace. “We’re incredibly grateful to our clients for their trust and to our team for making this achievement possible.”

If you are one of those clients, thank you. You came back year after year, and some of you sent friends our way. That is the growth this ranking measures.
