Specify the tax code to be used to post the payment line. The tax code defines the rate, the rules and the terms for the tax deduction applicable to the operation. 
 This code is only entered if:

• The payment attribute of the line makes use of an account subject to VAT,
• for Bank<=>BP payment attributes, the pre-payment account or the payment header account is defined with VAT management,
• for the other payment attributes (Account<=>BP and Bank<=>Account), the payment line account, either coming from the accounting code of the payment attribute, or previously entered, is defined with VAT management.

The tax code proposed by default is that of the open item allocated to the payment line, or that of the account determined as specified above.
