How do our values make Greenback so unique? Find Out

The answer is simple – we are the US expat tax preparation experts. Filing taxes can be simple and hassle-free when you are working with a company who understands the challenges of filing as an American living overseas.

Our founders, David and Carrie McKeegan, were expatriates themselves and were frustrated by how difficult (and expensive!) it was to file their US taxes. So they created Greenback Expat Tax Services—the kind of company they would want to work with themselves!

Some companies say they are customer-service focused, but Greenback truly cares about each and every client. We strive to exceed expectations every step along the way. In addition to being expat tax experts, Greenback accountants are committed to the highest level of customer service.

Expats are often hesitant to prepare their taxes entirely online—it isn’t easy to trust something so personal to someone you have never met! We understand—and we only hire accountants who have expertise and a strong commitment to providing the best possible experience for our clients. Each team member goes the extra mile to take care of our clients. Whether it is finding every possible deduction to reduce your tax liability or providing a timely answer to a question, all Greenback team members must go above and beyond the call of duty!

Easy to Work With

The process of filing US taxes with Greenback is fast and easy with our online system for sharing documents. But even more importantly, our accountants do all the heavy lifting when it comes to your tax return. We don’t make you do any of the financial calculations (as many firms do)—that’s our job! We also take great care to explain taxes in simple terms that you can understand. No one likes tax jargon and our accountants are excellent communicators who truly want you to understand what they are doing and why. Clients are always encouraged to ask questions at any time and they receive timely, accurate and understandable answers.


We use the highest security standards so your private information stays private as we completely understand the hesitancy to share personal information over the internet. When the company began in 2009, people generally weren’t as comfortable working virtually as they are today. But we have continued to evolve over time, constantly refining our security standards to match the latest technology available.

The client’s privacy and security is paramount which is why Greenback uses 256-bit data encryption. This is the same encryption that most banks use. We also provide each client with a personal, secure online folder to upload their secure files. This secure folder is password-protected and only their accountant has access to the files.
