Tax Number 

Definition

An identification number issued by the tax authorities to taxpayers.

You may need to quote your business partners’ tax numbers in business correspondence with them (such as in invoices), or when you file reports with the tax authorities. The exact requirements vary from country to country.

Use

You enter your business partners’ tax numbers in the business partner master data, on the Identification tab. The system automatically runs checks on some tax numbers (for example, to make sure that the check digit is correct).

Integration

In Customizing for Business Partner, you specify which tax number categories you need to be able to enter in your business partner data, by choosing Basic Settings ® Tax Numbers ® Maintain Tax Number Categories.
