What is an EIN?

An Employer Identification Number (EIN) is a unique nine-digit number assigned by the Internal Revenue Service (IRS) to business entities operating in the United States. It's essentially a Social Security number for your business, used to identify it for tax purposes. While sole proprietorships without employees may not always need an EIN, LLCs and corporations are generally required to obtain one.

How to Apply for an EIN

  1. Determine Your Eligibility: Ensure your mobile development business structure (LLC, corporation) requires an EIN. Sole proprietorships without employees might not need one, but it's often beneficial for liability protection and credibility.
  2. Choose Your Business Structure: Decide on the legal structure of your mobile development business (e.g., LLC, S-corp, C-corp). This decision impacts your tax obligations and liability. In DC, forming an LLC is a popular choice for its flexibility and liability protection.
  3. Prepare Form SS-4: Complete IRS Form SS-4, Application for Employer Identification Number. You can download this form from the IRS website. It requires information about your business, such as its name, address, and the reason for applying.
  4. Submit Your Application: You can apply for an EIN online through the IRS website, by fax, or by mail. The online application is the fastest method and generally results in immediate approval.
  5. Receive Your EIN: If you apply online, you'll receive your EIN immediately after submitting the application. If you apply by fax or mail, it may take several weeks to receive your EIN.
  6. Use Your EIN: Once you receive your EIN, use it to open a business bank account, file taxes, and hire employees or contractors. Ensure you include your EIN on all official business documents.
