Do not respond in any way that might be construed as a confirmation or a rejection of the validity of the taxpayer's response. The purpose of asking the questions is to obtain information for consideration, not to provide information to the taxpayer. Indications of confirmation or rejection would constitute providing information to the taxpayer.

On the TIN-Related Problem Research Sheet record the answers you receive.

We can make a determination without the questionnaire and documents in our file, but if an ownership determination is not made, the taxpayer will not receive their refund unless they have met all the conditions of IRM 21.6.2.4.3.3, Determining if the Scrambled SSN Indicator (SCI) Should be Removed.

A True Scrambled SSN Case requires the actual documents, completed by the taxpayer, for the file going to SSA. If you believe the number is a True Scrambled, tell the taxpayer to send the documents requested in the Letter 5064C and the questionnaire as soon as possible.

After all the questions have been asked and the answers recorded, state the following to the taxpayer:"Thank you for the information you have provided. When we have completed our gathering and reviewing of information, we will notify you by mail of our determination. The expected time frame for the process of review and notification is generally 6 to 8 weeks. If possible, we will issue our determination more quickly than the expected time frame." "Please keep in mind the information we provided earlier in the conversation: The IRS does not issue Social Security Numbers, and the IRS does not determine who the true owner of the Social Security Number is for the purposes of Social Security benefits. The Social Security Administration is a separate government agency and is the final authority on determining the ownership of the Social Security Number. We recommend strongly that you contact your local Social Security Administration office to ensure that your Social Security records are correct. The questions we have asked today, consequently, pertain only to the filing of your federal income tax return."
