Section 10(14): Allowances to Employees
Section 10(14) provides exemptions for certain allowances received by employees, which are meant to cover specific expenses incurred during their employment. These allowances are exempt from tax up to a certain limit if they meet the prescribed conditions.
Common Allowances Covered:
House Rent Allowance (HRA): Exemption is available for employees living in rented accommodation. The exempt amount is calculated based on the actual rent paid, HRA received, and the city of residence.
Transport Allowance: Provides a tax exemption for transport expenses incurred by employees who use their own vehicles for commuting to work. The exemption is up to ₹1,600 per month.
Conveyance Allowance: This includes allowances given to employees for commuting between their residence and place of work. The exemption is limited to the amount actually incurred.

Rent Paid: ₹15,000 per month
City of Residence: Mumbai (metro city)
Assuming the salary (basic + DA) is ₹50,000 per month:
50% of Salary = ₹25,000
Rent Paid – 10% of Salary = ₹15,000 - ₹5,000 = ₹10,000
The exempt HRA amount is the minimum of the following:
Actual HRA received: ₹20,000
Rent Paid – 10% of Salary: ₹10,000
50% of Salary: ₹25,000
Here, the exempt HRA amount would be ₹10,000 per month. The remaining ₹10,000 (₹20,000 - ₹10,000) would be taxable.
