United States Australia Tax Service is a boutique international tax firm, focused on assisting individuals, expatriates, and businesses with US, AU, and NZ tax planning, consulting, and return preparation where there is a connection with either the United States, Australia, and/or New Zealand. While the IRS does not have offices in Australia, we serve clients all over Australia, Asia  and the United States from offices in Sydney, Bangkok and San Francisco California

What if you haven’t done your U.S taxes for many years.

Many U.S. Expatriates and Green Card holders are unaware that they have a requirement to file a U.S. income tax return. As a result they have a large number of unfiled returns. We are experts in correctly completing past due returns for U.S. Citizens and Green Card holders with this problem. There are now several IRS programs that  will allow individuals residing  overseas to come into full compliance with the IRS waiving all penalties. If you find yourself in this difficult situation, rest assured we are able to bring you up to full compliance in the eyes of the Internal Revenue Service with minimal stress. Contact us today for a consultation on how we can help you.”
