Incorporate Your Business

Answer a few questions. We'll take care of the rest.


Plan to complete the entire application in a single sitting. If you remain inactive for more than 15 minutes, the online assistant will reset, and none of your information will be saved. Likewise, if your system happens to crash during the process, you will have to start over. As soon as you finish the application and submit it, you will receive your number. The IRS will mail a hard copy to you, but you should request an additional confirmation letter so that you have proof that you have applied for your federal tax ID number. The confirmation letter will arrive in a PDF format, so you will also need to install Adobe Acrobat Reader or another pdf reader, if you do not already have one.

If you would prefer not to apply for your federal tax ID number online, you can always pick up an SS-4form from your courthouse or the IRS. You can also download the form from the IRS website, print it, fill it out and mail it to the IRS. You can expect to receive your federal tax number within 10 to 14 business days.
