To obtain an EIN, file Form SS-4.  The IRS sets up its records using basic information provided by Form SS-4 (business name, address, owner's name, etc.).  File Form SS-4 for your business if you have no EIN and:
  • have a Keogh retirement plan,
  • pay wages to employees, or
  • are required to withhold taxes, or
  • are required to file an excise, fiduciary, or
  • alcohol, tobacco, and firearms return.             

Also, certain types of taxpayers (trusts, corporations, partnerships, non-profit organizations, and estates) must have an EIN even if they have no employees.  If you buy or take over someone else's business, you do not use the EIN of the previous owner.  In any of the above situations, apply for a new one.  However, if you operate more than one sole proprietorship, you must use the same EIN for each.

Once you have received an EIN, you can use it from one year to the next.  If you change your business from a sole proprietorship to a corporation or partnership, apply for a new EIN.  If you have filed an SS-4 but have not received an EIN by the time your first return is due, write applied for and the date applied for in the EIN space.  Fill out the SS-4 with the information requested in each box.  Many businesses report income based on a calendar tax year.  Others report income based on a fiscal tax year.  A fiscal tax year is a 12-month period ending on the last day of any month orther than December.  Enter the last month of your tax year on line 11.  If you're not sure which tax year you will use, enter not established on line 11.  Because it takes several weeks to receive an EIN after the Form SS-4 is filed, apply for your EIN well before your tax returns are due.  File for SS-4 with the Internal Revenue Service (IRS).  You can obtain an EIN by telephone.  See the Instructions for Form SS-4 details.
