Ha ha, no I've paid a variety of taxes: income, professional, capital gains... I've been an employee and now a startup founder. I also help others with taxes.

The script does have a field for EMPLOYEE_TAX_DEDUCTION. It defaults to 1.6 lac, assuming 1.5 lac for 80C and 10K for the rest (like medical insurance under 80D or whatever). But you can change it to whatever number you want to include other exemptions like HRA and LTA.

I think some things like PF and HRA are calculated based on basic income, but I was able to approximate the calculation without bringing basic income into account. Salary for the purpose of PF is limited to 15K anyway.

Again, enhancements welcome.
