HONG Kong people who migrate to the United States could be caught out by taxation changes before the House of Representatives.
Accounting firm Price Waterhouse said the first of the two proposed changes, contained in the Tax Compliance Act of 1995, only affected immigrants who later decided to relinquish their US citizenship.
In the past, individuals were able to give up citizenship with minimal tax consequences. But, under the new amendment, people leaving the US tax system will face a toll on their assets worldwide.
Jane Barbeau, senior taxation manager at Price Waterhouse, said the charge would be calculated on the current market value of the individual's assets.
If, after routine deductions, the final figure exceeded US$600,000 (HK$4.6 million) they would be required to pay income tax.
Ms Barbeau said this change could cause enormous complications and would force people to pay tax on assets in which they may have invested long before migrating to the US.
