Can you get an EIN before incorporating? You must incorporate your business before applying for an employer identification number with the IRS. Form SS-4, which is the EIN application, indicates that the name of the applicable business entity must be entered exactly how it appears on incorporating documents. Incorporating before the EIN application allows you to include your business's exact legal name. However, if you own a sole proprietorship or partnership and don't currently plan to incorporate, you can use your Social Security number for tax purposes and to register for an EIN. If this changes in the future, you can update the necessary authorities.

What Is an EIN?

The employer identification number, along with your business license, is one of the more important documents for your new business. While you must have articles of incorporation in hand when applying for your EIN, you do not necessarily need to have your business license. However, this depends on your jurisdiction. If you have a sole proprietorship, you can use your Social Security number to pay taxes for your business.

If you plan to incorporate or hire employees in the future, you'll need an EIN. If you have a sole proprietorship or partnership, and are using your Social Security number for taxation, you must notify tax authorities, banks, and creditors if you do register for an EIN down the road. This is especially important for your business to remain in compliance with federal, state, and local labor and wage requirements.

How Do You Apply For an EIN?

You can quickly and easily apply for an EIN online by filling out the digital version of Form SS-4. In some cases, the IRS may request a faxed version of the form along with your company's articles of incorporation for verification purposes. To be eligible, you must already have either a Social Security number or individual taxpayer identification number (ITIN), and your business must be located in the United States.

How Do You Apply For a Business License?

The rules for your business license are established by the county and city where your business is located. You may need a license associated with zoning, sales tax, or other purposes. In a few states, like Washington, business licenses are issued at the state level and are consistent for all municipalities.

In some municipalities, an EIN or tax identification number (TIN) will be required on your business license application. If you have not yet registered for an EIN, your Social Security number will suffice. You may also have to list the TIN or SSN of all the directors, officers, and owners of the business depending on the state and local laws.
