Quick Summary
- An Employer Identification Number (EIN) is a unique nine-digit taxpayer identification number assigned by the IRS to identify entities operating in the United States
- Just like a social security number is for residents, an EIN is for businesses. It is mandatory for various actions, such as filing taxes, opening bank accounts, and hiring employees
- For those running businesses in both the United States and the UK, note that an EIN is equivalent to the VAT.
What Is an LLC EIN Number?

An LLC EIN is an Employer Identification Number assigned by the IRS to identify limited liability companies for tax and financial purposes.
The main EIN purpose is best seen when you may need to provide your EIN to banks when applying for a business loan for your LLC, vendors, and other businesses when opening a business account or transacting business.
If you are not sure whether you should apply for the EIN, check with the IRS.
Applying for a business license is also one of the reasons why you might need to get an EIN.
You can find out more about business licenses in your area by contacting your local chamber of commerce or visiting their website.
A limited liability company is under the obligation to file tax returns, no matter if it chooses to be taxed as a sole proprietorship, partnership, or corporation.
You will need to provide your business taxpayer identification number on the tax return, whether filing it yourself or hiring a tax preparer.
Even if you own a single-member LLC or a multi-member LLC with employees, you will need a federal tax ID.
The Internal Revenu Service website has an extensive list of categories requiring an EIN application.
Some of them include business entities that pay excise taxes, withhold taxes on income, or do business in real estate.
Visit the IRS website for a detailed list of business entities that need an EIN.
