The first 92,900 USD of EARNED income (e.g., wages) can be excluded from your US income tax return. Any additional income will be taxed at the rates which would have applied had no exclusion been granted. You will be taxed in Singapore only on income earned in Singapore. So you could end up with double taxation as there is no personal income tax treaty with Singapore.
SOME PEOPLE TRY TO TURN BACK THEIR ODOMETERS. NOT ME. I WANT PEOPLE TO KNOW WHY I LOOK THIS WAY. I'VE TRAVELED A LONG WAY, AND SOME OF THE ROADS WEREN'T PAVED. ~ Will Rogers
