The Internal Revenue Service (IRS) office serving India is located in Philadelphia, and provides U.S. Federal tax assistance to Americans in India.
The IRS Home Page, www.irs.gov, has a lot of information available to answer many questions. Go to ‘Individuals’ and then ‘Overseas Taxpayers’ you will find a section of FAQ, which will take you to IRS Publication 54. Many questions of overseas taxpayers can be answered from that source.
US citizens’ income tax liabilities are based on worldwide income, so you’re still responsible to pay the IRS on income earned in India or other countries. You do get an $80,000 dollar exemption on money you earn overseas, so the tax burden will be significantly lower. In some countries, you can get foreign tax credits, but that’s only useful if the country you’re in has a higher tax rate than the US.
