All guidesHRA Exemption Explained: How to Calculate It and Save Tax
Under Section 10(13A) and Rule 2A, your exempt HRA is the lowest of three statutory amounts: actual HRA received, 50% of basic salary in metro cities (40% in non-metros), or actual rent paid minus 10% of basic. For an employee with ₹50,000 monthly basic receiving ₹25,000 HRA and paying ₹20,000 rent in a metro, exempt HRA is ₹15,000 monthly (₹1,80,000/year). Assuming the top 30% tax slab (+ 4% cess), this saves ₹56,160 in tax, or ₹37,440 in the 20% slab.
CTC vs In-Hand Salary: Why Your Take-Home Is Lower
A ₹12,00,000 annual CTC (Cost to Company) does not mean ₹1,00,000 credited to your bank account monthly. After deducting employer PF (₹4800/mo), gratuity provisions (₹1924/mo), employee PF (₹4800/mo), and professional tax (₹200/mo), your pre-tax monthly take-home is ₹88276. Under the New Tax Regime (FY 2026-27) with the ₹75000 standard deduction, income tax TDS is ~₹4909/mo, leaving ₹83367 net in hand.
