will take into consideration if people are not from india?

[pavitraag]

I am going to use this formula to calculate income taxes: Gross Salary - Deductions = Taxable Income; Income Tax = (Taxable Income x Applicable Tax Rate) - Tax Rebate.
This is used in India and almost similar to this US, UK and Australia also has this formula to calculate.

Not what I meant.
The percent of tax to be deducted are different for different brackets of salaries.

[pavitraag]

Each country has its own set of income ranges and corresponding tax rates.
I am working on India only for now
-Income up to ₹250,000: No tax
-Income from ₹250,001 to ₹500,000: 5%
-Income from ₹500,001 to ₹1,000,000: 20%
-Income above ₹1,000,000: 30%
