eTax for Ghana

Hello Every Body,

We need to implement eTax for Ghana, because they have change some Tax Flux.

If we sold something at 100 we need to apply the following

100     is the base line

    2.5  is the Get Fund tax at 2.5% and it should be applied on the Gross Amount Line

    2.5 is the NKIL tax at 2.5% and it should be applied on the Gross Amount Line

17.85 is the amount VAT at 17% applied on 100+2.5+2.5=105

Is somone can be help me?

Many thanks for your help.
