FAQ

Does an EIN cost money?

No. The IRS issues EINs free. Any website charging for this is a third-party service.

How long does it take?

Instant for online applications during IRS business hours.

Can I use my SSN instead?

Only single-member LLCs with no employees technically can. Not recommended — use a separate EIN for privacy and professionalism.
