Tax Number 

Definition

A number assigned by the tax authorities to every person and corporation. In Mexico, the tax number is known as the número de registro federal de contribuyentes (RFC).

Use

The tax number is used for reporting to the tax authorities.

You maintain your customers’ and vendors’ tax numbers in their master records, in the Tax code 1 field on the Control data tab (customers) or on the Control data screen (vendors) (see Creating a Customer Master Record Centrally and Creating a Vendor Master Record Centrally). You maintain your own tax numbers in Customizing for Financial Accounting, under Financial Accounting Global Settings ® Company Code ® Enter Global Parameters.

Structure

The structure of the tax number is different for persons and corporations, as follows:

The tax number for persons is 13 characters long. The first four letters are taken from the person’s name, then follows their date of birth (YYMMDD), then three letters chosen at random. An example would be Monique Maldonado Lemarque, MALM620202GQ1.

The tax number for corporations is 12 characters long. The first three letters are taken from the business’s name, then follows the date of its registration (YYMMDD), then three letters chosen at random. An example would be Sportswear Company (SWC), SWC920404DA3.
