Purchase and Sales Tax Based on formula

Hello, I would like to request an improvement for computing taxes in purchases or sales. Is it possible that we can put an entry in the tax table wherein the rate is a formula? Because in my country, we first divide the amount to 1.12 and then multiply by 0.12 for tax inclusive transaction. Or is there a way to do it in the current version? Thank you

In ERPNext you can simply use Tax included in Basic rate to avoid this (presuming the Item rate includes the tax amount). Please see this documentation -
