Does My Single Member LLC Need Its Own EIN?

An LLC is an entity created by state statute. The IRS did not create a new tax classification for the LLC when it was created by the states; instead IRS uses the tax entity classifications it has always had for business taxpayers: corporation, partnership, or disregarded as an entity separate from its owner, referred to as a “disregarded entity” An LLC is always classified by the IRS as one of these types of taxable entities. If a “disregarded entity” is owned by an individual, it is treated as a sole proprietor. If the “disregarded entity” is owned any any other entity, it is treated as a branch or division of its owner.

Single Member LLCs with Employees

For wages paid on or after January 1, 2009, single member/single owner LLCs that have not elected to be treated as corporations may be required to change the way they report and pay federal employment taxes and wage payments and certain federal excise taxes. On Aug. 16, 2007, changes to Treasury Regulation Section 301.7701-2 were issued. The new regulations state that the LLC, not its single owner, will be responsible for filing and paying all employment taxes on wages paid on or after January 1, 2009. These regulations also state that for certain excise taxes, the LLC, not its single owner, will be responsible for liabilities imposed and actions first required or permitted in periods beginning on or after January 1, 2008.

If a single member LLC has been filing and paying employment taxes under the name and EIN of the owner, and no EIN was previously assigned to the LLC, a new EIN will be required for wages paid on or after January 1, 2009. If a single member LLC has been filing and paying excise taxes under the name and EIN of the owner and no EIN was previously assigned to the LLC, a new EIN will be required for certain excise tax liabilities imposed and actions first required or permitted in periods beginning on or after January 1, 2008. The following examples may assist in determining if a new EIN is required:

  • If the primary name on the account is John Doe, a new EIN will be required.
  • If the primary name on the account is John Doe and the second name line is Doe Plumbing (which was organized as an LLC under state law), a new EIN is required.
  • If the primary name on the account is Doe Plumbing LLC, a new EIN will not be required.

You will be required to obtain a new EIN if any of the following statements are true.

  • A new LLC with more than one owner (Multi-member LLC) is formed under state law.

  • A new LLC with one owner (Single Member LLC) is formed under state law, and has an excise tax filing requirement for tax periods beginning on or after January 1, 2008 or an employment tax filing requirement for wages paid on or after January 1, 2009.
