Tax Compounding.

 I want to know how to go with tax compounding, would appreciate if you could reply to the both scenarios separately.

 

Scenario 1

 

VAT 12% - Setup is done and working properly.

NBT 2% - Setup yet not done.

 

The compounding I want in this scenario means 2% NBT applied on Invoice + VAT Amount. Tax rule should work in such a way that a choose a tax classification code and it first calculates VAT on Invoice amount and afterwards calculates NBT on Invoice + VAT amount automatically.

 

Scenario 2

 

VAT 12% - Setup is done and working properly.

NBT 2% - Setup yet not done.

 

The compounding I want in this scenario means 2% NBT applied on Invoice amount only.  Tax rule should work in such a way that a choose a tax classification code and it first calculates VAT on Invoice amount and afterwards calculates NBT on Invoice amount automatically.
