When will I be able to use my EIN?

This EIN is your permanent number and can be used immediately for most of your business needs, including:

  • Opening a bank account
  • Applying for business licenses
  • Filing a tax return by mail.
However, it will take up to two weeks before your EIN becomes part of the IRS's permanent records. You must wait until this occurs before you can:
  • File an electronic return
  • Make an electronic payment
  • Pass an IRS Taxpayer Identification Number matching program.
