Frequently asked questions
Do I need an EIN for my Arizona LLC?
If your LLC has more than one member, employees, or you want to open a business bank account, yes. Single-member LLCs without employees can use an SSN — but most Arizona founders still get an EIN to keep personal and business finances separate.
Can non-US residents get an EIN?
Yes. The process is slower and requires fax filing rather than the online portal. We handle the full process for foreign founders forming Arizona entities.
