Does My Business Need An EIN?

The business owners that are legally required to have an EIN are the ones that:
  • hire employees
  • operate as corporations to conduct business activities
  • withhold taxes on income paid to nonresident aliens
Having a corporation, multi-member LLC, or partnership requires you to apply for an EIN number.  If you have an EIN, you stay compliant with regulatory, legal, and financial matters.
Any time you change business structure, you must obtain a new Employer Identification Number. For example, changing from a partnership to a corporation.
Likewise, you will need an employer identification number if your business files for bankruptcy. 
#DidYouKnow You can only use an EIN for one business. If you open a second business, you must apply for a different employer identification number.
Sole proprietorships and single-member LLCs without employees can use their SSN instead of an EIN. Although, there are 3 benefits of having an Employer Identification Number that you should consider:
  • An EIN projects to others that you're a legitimate and professional business owner whether you apply for credit or conduct business with suppliers and vendors.
  • Another fundamental reason to have an EIN is privacy, regardless of which type of legal business structure you have. By keeping your SSN private, you reduce the chance of being a victim of identity theft.
  • Some business owners get an EIN to separate their personal and business taxes. This provides a better organization for business and personal finances.
If you have already applied for and received your Employer Identification Number, keep it safe. Rest assured, you can still verify EIN number if you ever lose the IRS card that includes the number.

When Should You Change Your EIN?

Ownership and business structure changes require a new EIN under these conditions.

Trust Owners

When a single person is a grantor for several trusts, the trust changes to an estate, a living trust changes to a testamentary trust, or a living trust ends. 

Can You Cancel An EIN?

Once the IRS issues an EIN, the only way to cancel it is to close your business.  Send a letter to the IRS that includes the business's legal name, the EIN, business address, and why you want to close the account.  Attach a copy of the original EIN assignment notice to speed up the process.
