Understanding CIS Company Constants

Use CIS Company Constants (P74U0101) program to enter this information about the contractor:

  • CIS tax reference number

  • Unique tax reference (UTR)

  • Tax office number

  • Account office reference (AORef)

The UTR consists of a check digit followed by 9 numeric digits. The system validates the first character of the UTR.

The AORef that you enter must be in this format:

  • Characters 1, 2, and 3 are numeric.

    Use leading zeros (0) to complete the 3 characters, if necessary.

  • Character 4 must be the letter p.

  • Character 5 must be alpha.

  • Characters 6–13 must be numeric.

    Use leading zeros (0) to complete these characters, if necessary.

The system validates the requirements for the characters entered for the AORef.

The system saves data about the CIS company constants to the CIS Company Constants (F74U0101) table and the CIS Company Constants 2007 Update (F74U0111) table.
