EIN for Different Legal Entities
For sole proprietorships, you can only be issued one EIN number. For multi-member businesses such as a corporation or LLC, there is no limit to the number of EINs you can have.
Having Multiple EINs
Do you need multiple EIN numbers for different businesses? You need multiple EINs if you have multiple separate legal entities. For example, if you have 5 corporations, you can apply for 5 separate EINs. If you have unincorporated businesses that are not distinct legal entities, then you only get 1 EIN.
Managing Multiple EINs
What happens if you have two EIN numbers? If you have two EIN numbers, contact the IRS. They will likely tell you to use one number for your business dealings and disregard the other. Having two causes confusion and makes it difficult for the IRS to track your business.
Obtaining Multiple EINs
How do I get more EINs? To get more EINs, complete an online application for each one. You must request one EIN at a time on separate days.
Finding Your EIN
Where can I find my EIN? If you are unsure if you have an EIN, there are many ways to look it up – check filed tax returns, business credit reports, loan documents, bank statements, or contact the IRS directly.
Changing Business Name on EIN
Can I change my business name on my existing EIN? Yes, in some situations you can change the business name on your EIN by sending a request to the IRS. In other cases, a name change may require a new EIN.
EIN for Single-Member LLC
Should I get an EIN for my single-member LLC? Yes, an LLC requires an EIN for tax purposes, even if it has just one member.
Limit on EINs
Is there a limit on how many EINs I can have? There is no limit on EINs for partnerships, corporations, or multi-member LLCs. Sole proprietors can only have one EIN.
Using EIN Across Multiple Businesses
Can I use one EIN across multiple businesses? No, you cannot use the same EIN for different legal entity types or for unrelated businesses.
Applying for New EIN
Can I apply for a new EIN if I already have one? In summary, yes. As long as each EIN is for a separate business entity, you may apply for multiple EINs. Remember, you must request one EIN at a time and not on the same day.
