Moving to Europe as an American: The
Tax Mistakes That Can Cost You Dearly.
For Americans moving abroad, the dream of a new life in Europe can quickly become complicated by US tax rules, foreign reporting requirements, estate planning mismatches, and costly investment mistakes.

How New York’s ‘extremely aggressive’
