ITIN reasons and qualification
You have to meet the return filing reason , or one of the exception-to-return-filing reasons. One cannot just arbitrarily apply for an ITIN as you must include documentation proving that you need one and that your reason aligns with IRS qualification requirements to receive one. The IRS sets out a finite prescribed list of qualification requirements – all split into two groups – IRS-return-filers OR exceptions. One reason that can be used for many applicants when they can’t qualify under other reasons, is owning many but not all types of USA bank accounts (so long as the US bank provides you with the required ITIN letter).
Individuals who are partners of a U.S. or foreign partnership that invests in the United States and that owns assets that generate income subject to IRS information reporting and federal tax withholding requirements
