SURCHARGE ON SALARY INCOME AND CAPITAL GAINS

To calculate the surcharge amount and marginal relief on gross salary income and long-term capital gains (LTCG) on property, we'll need to consider the tax slabs and surcharge rates for the financial year 2023-24.

Assuming the individual is a resident individual and has no other income except the gross salary income and LTCG on property, here are the calculations: 

Gross Salary Income: Rs. 2,03,00,000 - Taxable income (after deductions and exemptions): Rs. 2,03,00,000 (assuming no deductions or exemptions) -

 Tax liability (as per old regime): Rs. 63,37,500 (using the tax calculator or tax tables) - Surcharge (10% of tax liability): Rs. 6,33,750 -

Total tax liability (tax + surcharge): Rs. 69,71,250 LTCG on Property (with indexation): Rs. 3,10,00,000 - LTCG (after indexation and exemptions): Rs. 3,10,00,000 (assuming no exemptions) -

 Tax liability (20% of LTCG): Rs. 62,00,000 - Surcharge (10% of tax liability): Rs. 6,20,000 -

Total tax liability (tax + surcharge): Rs. 68,20,000 Marginal relief is applicable when the surcharge is more than the tax liability. 

In this case, the surcharge on salary income is Rs. 6,33,750, which is less than the tax liability. 

However, the surcharge on LTCG is Rs. 6,20,000, which is also less than the tax liability. Therefore, marginal relief is not applicable in this scenario. 

Please note that these calculations are simplified and do not consider other factors that may impact tax liability, such as other income, deductions, exemptions, or tax credits.
