Does the New Mexico Secretary of State issue my EIN?

No, and this is a common mix-up: your EIN comes from the IRS, a federal agency, not the New Mexico Secretary of State, which handles your state entity registration. You need both, the New Mexico filing to create the entity and the federal EIN to bank and file taxes. We obtain the EIN and complete the New Mexico registration together so nothing is missing.

Do I need my New Mexico entity before I get an EIN?

Usually yes: you generally form the entity with the New Mexico Secretary of State first, then apply for the EIN in the entity's exact legal name, so the IRS record matches the New Mexico record. Applying out of order can create a name mismatch. We sequence the New Mexico filing and the EIN so they line up cleanly.

Can a non-US founder get an EIN for a New Mexico entity?

Yes: you do not need an SSN to obtain an EIN for a New Mexico LLC or corporation; the IRS has a process for foreign responsible parties, though it takes longer than the online route. It is a common step for international owners. We obtain the EIN for your New Mexico entity even without an SSN so you can bank and operate.

What do I use my EIN for after forming in New Mexico?

To open a business bank account, hire employees, file federal and often New Mexico taxes, and identify the business instead of your SSN. It is the entity's federal tax ID. We make sure your New Mexico entity has its EIN in hand so banking and payroll are not held up after formation. Link llc-bank-account? no hub. Link get-an-ein.

Does each New Mexico entity need its own EIN?

Generally yes: each separate LLC or corporation you register with New Mexico should have its own EIN, since sharing one across entities blurs the tax and liability lines. A single-member LLC with no employees can sometimes use the owner's SSN, but a distinct EIN is cleaner. We obtain an EIN per New Mexico entity so each stands on its own. Link holding-company.

Do I need a separate New Mexico state tax ID too?

Often, if you have employees or collect sales tax: the federal EIN is one number, and New Mexico issues its own state tax or employer account number when you register for payroll or sales tax. They are different IDs for different filings. We obtain the EIN and complete the New Mexico state tax registrations you actually need. Link sales-tax-registration.

Can File.Business get my EIN with my New Mexico formation?

Yes. We form or register your entity with the New Mexico Secretary of State and obtain the federal EIN in the same process, including for non-US founders without an SSN, so you leave with both the state registration and the federal tax ID rather than chasing the IRS separately.
