Talk to an accountant, since I think you are very likely to be vastly overpaying your taxes.  See following for a list, and I have some personal recommendations if you need themConsulate General of the United States Hong Kong & MacauNow1) there is no double taxation.  Your HK tax can be set up as a foreign tax credit from your US tax.  (Note: this has to be done carefully, so you should have an accountant do it once for you.  There are a lot of subtle issues here like the fact that the HK tax year is different from the US tax year, the difference between accural and cash basis, and the fact that taxes that come from income that you are excluding cannot be used as a credit.)2) you have an income and housing exclusion.  The net result of this is that your first USD 150K is not subject to US taxIf you have been double paying taxes, get an accountant *NOW*.  You can file amended tax returns for three years.Bottom line is that filling out the tax forms is painful, but the tax rates aren't that bad.  Part of your money will go to the US.  Part of it will go to Hong Kong.  Figuring which is which will take you over 30 pages.  My first years tax return was over 100 pages.  The amount wasn't that bad, but it was trying to split the year between the time I was in Hong Kong, the time I was in the US, the different tax years, and doing this three times to see if I hit the AMT or capital gains limits.
