Tax Rates 

When defining a tax code, you can specify tax rates for one or more tax types.

If you need to post input tax (15 percent) with a non-deductible portion (of 40 percent), define a tax code with both deductible and non-deductible rates. When defining this code, enter the portion for input tax (9 percent) under the tax type "Input tax", and the non-deductible portion (6 percent) under the tax type "Nonded.input tax".
