With over 30 years experience, I have helped many US citizens meet their US income tax and information reporting requirements. In 1987 I prepared 10 years of delinquent tax returns for a US citizen working outside of the US. Like many of you, it came as a surprise that he needed to file a US tax return in addition to the return in the country where he worked.
I work directly with the taxpayer or with the taxpayer's attorney, banker or foreign country tax advisor to bring the US tax compliance up to date. I focus on US citizens living in Switzerland and other European countries and non-residents requiring American tax filings.
