  • Trademark Registration: For unique brand protection nationwide, consider applying for a federal trademark.

An EIN, issued by the IRS, is a unique nine-digit number assigned to your business for tax purposes. Most businesses need an EIN, especially if they:

  • Hire employees

  • Operate as a corporation or partnership

  • File certain tax returns

Applying for an EIN is free and can be done online through the IRS website.

Depending on your location and business type, you may need to register for:

  • State income tax

Check with your state’s Department of Revenue or Taxation to understand your obligations.
