Q1. What is a name control?

A1. A name control is a sequence of characters derived from a taxpayer’s name that is used by IRS in processing the tax return filed by the taxpayer.  It is important that the combination of name control and taxpayer identification number (TIN) provided on an electronically filed return match IRS’s record of name controls and TINs.

A name control is established by the IRS when the taxpayer requests an Employer Identification Number (EIN).  The IRS creates the name control from the legal name listed on the Form SS-4, Application for Employer Identification Number.

When a return or extension is filed, the IRS checks whether a name/TIN combination is correct by matching it against a file containing all employer identification numbers (EIN) issued by IRS.

The name control listed on the return/extension is then compared to the name control on the IRS file. If it matches the name control in our records, it is considered to be correct.

Q2. Why is the name control important?

A2. In e-file, a taxpayer's Employer Identification Number (EIN) and name control in the Return Header must match the data in the IRS e-file database. If the EIN and name control do not match, the e-filed return will reject and generate an Error Reject Code.

Q3. Can I verify my partnership’s name control prior to e-filing?

A3. Yes.  IRS recommends that partnerships that have any question about the name control they will use in their e-filed tax return verify it before filing.  Here are ways name controls can be verified:

  1. Review the rules in the Business Name Control matrix that is in FAQ 4 below.
  2. If you have an IRS representative on-site, you may contact them for assistance.
  3. Call the Business & Specialty Help Line at 800-829-4933 for assistance.  You must qualify in one of the following categories to receive assistance:
  • Be a Tax Matters Partner
  • You are designated as the Paid Preparer and the paid preparer checkbox on the return is checked for the last filed return (The designation expires one year after the due date of the return in question. There are no exceptions or extensions to the expiration date)
  • Have or provide a Form 8821 Tax Information Authorization authorizing you  to discuss the partnership’s entity information

Q4. How can I determine my partnership’s name control using the Business Name Control matrix?

A4. The name control consists of up to four alpha and/or numeric characters.  It can be determined from the information specified on the first name line.  Generally, the name control is derived from the first four characters of the partnership name. An ampersand (&) and hyphen (-) are the only special characters allowed in the name control. The name control can have less, but no more than four characters. Blanks may be present only at the end of the name control.

Note: Do not include ''dba'' as part of the name control. The initials stand for ''doing business as”.

Business Name Control Valid Characters:

  • Numeric (0- 9)
  • Alpha (A-Z)
  • Hyphen (-),
  • Ampersand (&)

Special Business Name Control Rule:

If an invalid character is used in the name line, drop the special character from the taxpayer's name. Example: should be “JOEC”. Another example is The name control should be “4UCO”.
