Surcharge

A surcharge — or additional charge — is essentially a tax levied on a tax. It is calculated on payable tax, not on income generated. So a surcharge of, say, 10 per cent on an existing tax rate of 30 per cent effectively raises the total tax rate to 33%. For example, if a tax is imposed at 30 per cent on an income of Rs 100, the total payable tax would be Rs 30. Then, a surcharge of 10 per cent calculated on Rs 30 would amount to Rs 3. So, the effective payability would be Rs 30 + Rs 3 = Rs 33.
