Frequently Asked Questions
What is income tax surcharge?
Surcharge is an additional tax levied on high-income earners, charged as a percentage of the base income tax. It applies when taxable income exceeds ₹50 lakh. In India, surcharge rates range from 10% to 37% depending on income level and regime.
What is marginal relief in surcharge?
Marginal relief ensures that the extra tax (surcharge) paid on income exceeding a threshold does not exceed the additional income itself. For example, if your income is ₹51 lakh (₹1 lakh above the threshold), the surcharge cannot exceed ₹1 lakh — preventing effective tax above 100%.
Is the 37% surcharge still applicable after Budget 2023?
The 37% surcharge is only available under the old tax regime for income above ₹5 crore. Under the new tax regime, the maximum surcharge is capped at 25% for all income levels. This is a key reason why ultra-high earners benefit from switching to the new regime.
