One of the most common rejects on electronically filed tax returns occurs when the Taxpayer's Identification Number ('TIN'), either the Social Security Number ('SSN') or the Employer Identification Number ('EIN') does not match the records of the IRS. The Internal Revenue Service has issued guidelines for the Taxpayer Identification Number matching process and the development of name controls on returns submitted electronically.
All electronically filed returns must include a correct name and TIN combination to allow for the matching of the information reported against the income included on the payee’s income tax return. A verification check is performed by the IRS to determine whether the name/TIN combination is correct by matching it against a file containing all SSNs issued by the Social Security Administration or in the case of entities against a file containing all EINs and other TINs issued by IRS. The name control (if provided) on an electronically filed information return is compared to the name control on file. If a name control is not provided or is provided incorrectly, one is developed from the name(s) provided on the first two name lines (up to 40 characters for each name line including spaces) of the information return. If a match can be made, it is considered correct. If a match is not found, the name/TIN combination is considered incorrect.
A name control usually consists of up to four characters. To help ensure that the name/ TIN combination for an account matches the name/ TIN combination on SSA or IRS files, the IRS uses the following criteria when matching the different types of e-filed returns:
Individuals (Forms 1040, 1040NR)
The name control for an individual is generally the first four characters of the last name on the information return and the IRS uses the following criteria to establish the name control.
- The name control consists of up to four alpha and/or numeric characters.
- The hyphen (-) or a blank space are the only special characters allowed in the name control. These characters cannot be in the first position of the name control.
- The name control can have less, but no more than four characters. Blanks may be present only as the last three positions of the name control.
- If an individual has a hyphenated last name, the name control is the first four characters from the first of the two last names.
- For joint returns, regardless of whether the payees use the same or different last names, the name control is the first four characters of the primary payee’s last name.
