SS-4PR Fillable PDF – Apply for a Puerto Rico EIN

The SS-4PR is the IRS application used by businesses, trusts, estates, and other entities in Puerto Rico to request an Employer Identification Number (EIN). This number is required for tax reporting, opening bank accounts, and hiring employees.

What Is the SS-4PR Form?

Form SS-4PR is a Puerto Rico‑specific version of the standard SS‑4. It includes fields for the legal name, trade name, principal address in Puerto Rico, and the entity’s classification (corporation, LLC, partnership, etc.). The form is accepted by the IRS for all EIN requests originating in Puerto Rico.

• Legal name: Enter the exact legal name of the entity or individual requesting the EIN.
• Trade name (if different): Provide the DBA or “doing‑business‑as” name.
• Principal address: Must be a physical street address in Puerto Rico (no PO Boxes).
• Entity classification: Choose the correct box (Corporation, Partnership, LLC, etc.).
• Reason for applying: Select the appropriate reason (new business, banking, change of ownership, etc.).

Common Mistakes & Tips for a Smooth EIN Application

Avoid these pitfalls to prevent processing delays:

• Do not use a PO Box for the principal address.
• Make sure the name matches exactly with any existing state registrations.
• Provide a valid phone number and email – the IRS may need to contact you.
• Check the box for “Limited Liability Company” only if the entity is an LLC.
• Review the form for typos before submitting; even a small error can cause a rejection.
