When you donate to GWCOT, the benefit can be availed by reducing 50% of the donated amount from your taxable salary. For instance, if your taxable income per year is ₹200,000 and you make a donation of ₹5,000, then your net taxable income will become ₹197,500 (i.e. ₹200,000 – 50% of your donation). Your tax will now be calculated on this reduced taxable income based on the prevailing tax rates.
