Frequently Asked Questions
Can Ineo manage tax filings for employees in multiple countries? 
Yes, Ineo manages tax filings for employees across multiple countries, offering a coordinated approach to ensure accuracy and compliance worldwide.
Am I considered a resident alien or non-resident alien with regard to U.S. tax filing requirements?
Tax resident status is NOT the same as immigration status.
Some statuses allow you to be exempt from being taxed as a resident alien. The Green Card and the substantial presence test will help determine your tax residency status.
It is important to note that there are general tax rules regarding this area of U.S. taxation, and of course, there are many exceptions. In fact, for foreign nationals entering the United States, there could be a few dozen ways to possibly file the U.S. Federal tax return depending on the specific facts and circumstances of the transferee. For this reason, it is highly recommended to obtain assistance from a tax preparation service provider that is well-versed in this area of individual taxation to take advantage of any tax planning available. Contact our tax team today for assistance in your tax return preparation.
Does tax status determine if you need to report worldwide income?
Yes, if you are a resident alien, you are required to report worldwide income. Whereas for a non-resident alien, the type of income and from where it is sourced can impact whether it is reportable/taxable in the United States or not.
If I sell my home in my host country, does the U.S. tax my profit?
Yes, it does if you file your taxes as a resident alien. It is also important to supply your tax preparation service provider with details about the relinquishment of the underlying mortgage of the home sold.
