The purpose of today’s article is to describe why you need an EIN for your business entity. The acronym EIN stands for “employee identification number”. The IRS is the agency that issues the EIN for small businesses.

Most business owners want to separate their business operations from their personal life. In other words, they want to make sure that any liabilities they have in their personal life do not affect their business. The reverse is also true. Owners of small businesses often want to make sure that any liabilities that arise in their business operations do not affect their personal life and assets. 

The way that this is accomplished is when you create a separate business entity such as an LLC or a corporation. When you create a business entity such as this the law considers this business entity to be a separate legal person. Because of this there has to be a way that you can identify who that business entity is. Individual people have a social security number that proves who they are. Likewise, the EIN for a business entity identifies who the business is. In other words, the EIN in many ways acts like a social security number for the business entity. There are many things that you use your EIN for in your small business operations. 

Bank Accounts

The first thing that you would use your EIN for would be to establish and create any financial or other bank accounts needed for your small business. Again, when you individually go to open a bank account, they require you to use your social security number. Likewise, when you open up any bank accounts for your small business, you are required to have the EIN so the bank can identify that that bank account is owned by your business entity. 

Having a separate bank account for your business entity is vitally important in maintaining the separation of your business assets and liabilities from your personal assets and liabilities. If you commingle your personal financial accounts with your business, then in most instances the law would say that you do not have a separate business entity. This means that the corporate shield, or the protection that separates you personally from your small business, no longer exist. 

To keep the corporate shield in place and avoid any problems we recommend that you open up a checking account and at least one savings account associated with your business entity through your business EIN. We did recommend that you keep your business finances identified through your EIN completely separated from your personal finances at all times. 

Tax Filings

Another reason why you need an EIN for your business operation is so that you can file the appropriate tax filings. On every federal and state tax filing you are required to provide the EIN as well as the business name for your business operation. Again, this number acts as an identifier for your business so that the IRS and the state tax agencies can verify any and all taxes that may be owed by your business entity to the agency. 

Some people are surprised to learn that even when you have an LLC as your business entity, and you set it up so that it is a pass-through entity, a tax filing is still required. In other words, even if your LLC is not required to pay any taxes, it is still required to file a federal and state tax return every year. These tax filing documents show the income that passes through the entity to the owners, and it also shows the amount of income that goes to each individual owner. The LLC is then required to provide certain tax documents to each owner so they can include them in their own personal tax filings. 

On every one of these documents the EIN for the business entity is required to be listed. Most of these documents also require the business name as well as the address for the business. Most of these documents also require a listing of who the managing member or manager is so that the tax agency can contact a live human being if there are any questions. 


Last but not least, the EIN is required any time you have any employees. As the acronym states it is an “employer” identification number. The EIN number is then used for wage and compensation purposes, as well as others. These other reasons would include things such as employee retirement plans, Workers Compensation Insurance accounts, unemployment insurance accounts, and so forth. 

As you can see, regardless of whether your business entity actually has any employees or not, you were still required to get an EIN for your business entity. We have helped numerous business entities obtain their own EIN from the IRS and then use that EIN throughout their business processes and procedures. If you have questions or concerns we are confident that we can help you too!
