Frequently Asked Questions

Who needs an EIN?

If you’re a small business owner, chances are you don’t know what an employer identification number (EIN) is. But it could make sense to start collecting one now.

The IRS requires every business entity — whether it’s a corporation, limited liability company, or whatever — to have an EIN. In fact, it’s mandatory. If you don’t already have one, you’ll need to apply for one within 30 days of starting your business. You’ll pay $100 to file your application.

But there are some exceptions. For example, you don’t need an EIN if your business doesn’t have employees. And if you’re a sole proprietorship or single member LLC, you don’t need one either. So who needs an EIN?

The answer is simple for partnerships, corporations, and multi-member LLCs: Everyone.

That includes sole proprietorships and those single-member LLCs that don’t have employees. Why? Because having an EIN helps prevent tax fraud.

In addition to helping identify potential tax cheats, an EIN can also help protect small business owners against identity theft. When someone steals your personal information, such as your Social Security number, credit card number, etc., they can open fraudulent accounts in your name. An EIN makes sure that no one else uses your SSN.

Is an EIN the same as a tax ID number?

In New Mexico, there are three different types of business registration numbers: the Employer Identification Number (EIN), the Sales and Use Tax Report Number (TAN), and the Combined Reporting System Number (CRN).

The most important difference between the EIN and TAN/CRN is that the CRN is required to report the Gross Receipts Tax, while the EIN is not. However, you still must obtain both numbers to file your annual reports. You must apply for one if you do not receive a TAN/CRN.
