- Form your business entity first. Your Oklahoman LLC, corporation, or other entity must exist before applying for an EIN. Form an LLC in Oklahoma or form a corporation if needed.
- Pick your responsible party. The IRS requires one individual with substantial control over the entity (typically an owner with at least 25% interest) to be listed on Form SS-4.
- Apply online at irs.gov. US founders with a valid SSN or ITIN get the EIN immediately. The application is free and takes about 10 minutes.
