Anirudh stays in New Delhi. His basic salary is ` 10,000 p.m., D.A. (60% of which formspart of pay) is ` 6,000 p.m., HRA is ` 5,000 p.m. and he is entitled to a commission of1% on the turnover achieved by him. Anirudh pays a rent of ` 5,500 p.m. The turnoverachieved by him during the current year is ` 12 lakhs. The amount of HRA exemptunder section 10(13A) is –(a) ` 48,480(b) ` 45,600(c) ` 49,680(d) ` 46,800

The House Rent Allowance (HRA) exemption under section 10(13A) of the Income Tax Act is the least of the following amounts:

1. Actual HRA received
2. 50% of salary (for those living in metro cities, which includes New Delhi)
3. Rent paid minus 10% of salary

In Anirudh's case, we first need to calculate his salary. His salary includes his basic salary, the 60% of D.A. that forms part of his pay, and the commission he receives.

1. Basic salary = 10,000 per month x 12 months = 1,20,000 per year
2. 60% of D.A. = 60/100 x 6,000 per month x 12 months = 43,200 per year
3. 1% commission on turnover = 1/100 x 12,00,000 = 12,000 per year

So, his total salary = 1,20,000 + 43,200 + 12,000 = 1,75,200 per year

Now, we calculate the three amounts for HRA exemption:

1. Actual HRA received = 5,000 per month x 12 months = 60,000 per year
2. 50% of salary = 50/100 x 1,75,200 = 87,600 per year
3. Rent paid minus 10% of salary = (5,500 per month x 12 months) - (10/100 x 1,75,200) = 66,000 - 17,520 = `48,480 per year

The least of these three amounts is 48,480. Therefore, the amount of HRA exempt under section 10(13A) is 48,480. So, the correct answer is (a) `48,480.
