For example
Encoding expanse for house rant or consultancy services is not easy with the current system.

Accodring to the current scenario - using the module account_tax_include

- Product (service Type) cost is 5000
- Add Defaut tax on product is - 10% TDS

Now, Make a supplier invoice Price method (Tax Include) it will compte following.
Untaxed Amount : 4545.45
Tax : 454.55
Total : 5000.00

But according to the TDS calculations this is totally wrong. It should calculate like as follows
Untaxed Amount : 4500
Tax : 500
Total : 5000.00
