This specification provides the definition of the Tax control message (TAXCON) to be used in Electronic Data Interchange (EDI) between trading partners involved in administration, commerce and transport.

A Tax control message is used to enable the transmission of summary and control data for tax purposes. It is used to summarise and control the taxes (e.g. VAT) or duty which applies to a batch or batches of related messages.

The Tax control message may be used for both national and international applications. It is based on universal practice related to administration, commerce and transport, and is not dependent on the type of business or industry.

The message meets control needs imposed by administrations and can be used by individual users for their own control purposes.

The summary and control information is sent by the sender of tax related messages so the recipient may:

1. verify the integrity of the transmission, i.e. of the tax related messages sent.
2. maintain an archive of summary and control data of the tax related messages for audit purposes.

See UNTDID, Part 4, Chapter 2.3 UN/ECE UNSM - General Introduction, Section 1.

See UNTDID, Part 4, Chapter 2.3 UN/ECE UNSM - General Introduction, Section 2.

This section should be read in conjunction with the segment table which indicates mandatory, conditional and repeating requirements.

This group is used to specify references that relate to the whole message.

0050 RFF, Reference

This segment identifies relevant references, such as the previous Tax control message between the trading partners.

0060 DTM, Date/time/period

This segment specifies the date and time of the reference in the preceding reference segment.

This segment group carries all the control values.

0120 RFF, Reference

A segment specifying the relevant reference numbers to identify the source file, i.e. the file that provides all data for the batch of related messages. This may be the file generation number and the file version number.

0130 DTM, Date/time/period

This segment may be used to give the date of preparation of the file identified in the preceding reference segment.

0140 Segment Group 4: DOC-MOA-CNT-SG5

This group identifies the type of tax related messages and specifies the control totals for each type.

0150 DOC, Document/message details
