If you are any of the following, you must file a return:
The term trade or business generally includes any activity carried on for the production of income from selling goods or performing services. It is not limited to integrated aggregates of assets, activities, and goodwill that comprise businesses for purposes of certain other provisions of the Internal Revenue Code. Activities of producing or distributing goods or performing services from which gross income is derived do not lose their identity as trades or businesses merely because they are carried on within a larger framework of other activities that may, or may not, be related to the organization's exempt purposes.
Please let me know if I can be of further assistance to you regarding this matter.
Thank you again for using JUST ANSWER.
That is excellent information. However learned that there is a Tax Treaty between the Netherlands and the U.S. dated in 1993.
Could it be that under this treaty I'm exempt from filing a tax return?
