"When I was looking for a tax service I looked at several sites. Greenfield & Associate ’s site appeared to be very professionally done and I was pleased to find that they are very professional. Living overseas and retired, I needed someone who could help me to obtain the deductions to which I was entitled. Had I done the tax returns myself, I am sure I would have paid much more. The process is easy and they help you through it right up to paying your taxes. This is important if you don’t have a bank account in the USA. They are completely trustworthy and look after your best interest. I highly recommend Greenfield for assistance with your taxes.

I was a little late getting started on things, but they went the extra mile and turned everything around far more quickly than I expected. The whole process, from document transfer to review and filing was quick and easy – thanks very much!
