CD/DVD Information
CD/DVD Information
If you have 250 to 100,000 incorrect payee “B” records, your data will be on a CD. If you have over 100,000 payee “B” records then your data will be delivered on a DVD. Please make sure you have the correct type of reader. Many older readers only read CDs.
The enclosed CD/DVD is encrypted. You should be able to read it by putting it into a CD/DVD reader on your computer. If you have the “Auto-Run” feature turned on, the system should bring up a pop-up window asking you to: Please contact the IRS at 1-866-455-7438 to receive your encryption key. International callers may dial 304-263-8700. Have the following information available when calling: TIN, company name, primary or secondary contact and self assigned PIN number. This encryption key will be needed to unlock your CD/DVD.
If you do not have “Auto-Run” turned on, you won’t see the pop-up window. Contact the IRS at 1-866-455- 7438 to receive your encryption key. International callers may dial 304-263-8700. Please have the following information available when calling: TIN, company name, primary or secondary contact and self assigned PIN number. You should have filled out Form 10301 and returned it to the IRS. This form tells the IRS the self selected PIN that you would like to use.
When you view the CD/DVD there should be one file named “UDnnnn”**. This file will be an .exe file. When you double-click on the file a box will open asking for your encryption key. Put in your encryption key, click “OK” the next screen will ask you to browse the folder tree and select to where you want to extract the files. Click on “OK” and the files are extracted. Please make sure to keep tax data secure.
On the CD/DVD please find the files described below:
I40642.UAnnnn ** is the Payer A-Record file. 114 Characters.
I40642.UBnnnn ** is all the Incorrect Payee B-Records. Each 222 Characters.
I40642.UCnnnn ** is the Payer C-Record file. 37 Characters.
A Copy of Publication 1281. ** nnnn is the CD/DVD transmittal number.
Each file record layout is described below.
These files are .txt files; So if you read them with Note Pad, word processing software, etc. you will see the Pipe Codes “|” as separate characters between each field. If you open the file with Excel, you can read it as a delimited file set the delimiters as pipes “|”. You then will see the file laid out without the Pipe Codes “|”, just like Cartridges of past years. Be careful to set or convert fields to text so that leading zeros are not truncated or blanked out.
The IRS hopes this new delivery method meets most of your requests to move away from the tape cartridges.
