You only need the EIN, or equivalent number in whatever country you are in, if you are going to open a bank account for the trust. The EIN is “for banking purposes only” — not for filing tax returns. The EIN is required by the banks in the USA for opening accounts, as an identifier number only.
The EIN is very simple, easy, and quick to get, and it is free. It is done online on the IRS website and the trust writer can show you how to do it. It takes 15-20 minutes. Once the form is filled out, it just takes a few minutes or seconds for the system to generate it.
