How the HRA exemption is calculated
Section 10(13A) of the Income-tax Act, read with Rule 2A, exempts part of the House Rent Allowance your employer pays — but only under the old tax regime, and only if you actually pay rent for the home you live in. The exempt amount is the least of three figures:
- Actual HRA received from your employer for the year;
- Rent paid minus 10% of basic salary (never less than zero);
- 50% of basic salary if you rent in Delhi, Mumbai, Kolkata, or Chennai — 40% anywhere else.
Whatever is left of your HRA after the exemption is taxed as ordinary salary. Most calculators print only the final answer; this one shows all three limbs side by side and highlights the one that binds, because the binding limb is what tells you which lever actually moves your exemption. If limb 2 binds, the exemption grows rupee-for-rupee with rent; if limb 1 or 3 binds, paying more rent changes nothing. "Basic salary" here means basic pay plus dearness allowance that counts for retirement benefits, if your structure has DA — most private-sector structures do not.
Worked example 1 — the common case (limb 2 binds)
Annual basic ₹4,80,000, HRA received ₹2,40,000, rent ₹2,40,000 (₹20,000 a month) in Mumbai, a metro. The three limbs: actual HRA is ₹2,40,000; rent minus 10% of basic is ₹2,40,000 − ₹48,000 = ₹1,92,000; 50% of basic is ₹2,40,000. The least is ₹1,92,000 — exempt. The remaining ₹48,000 of HRA is taxable. Notice the arithmetic quirk: whenever rent equals HRA received, limb 2 is automatically the smallest, and exactly 10% of basic stays taxable.
Worked example 2 — non-metro, high rent (limb 3 binds)
Same salary — basic ₹4,80,000, HRA ₹2,40,000 — but rent of ₹3,00,000 a year (₹25,000 a month) in Bengaluru, which is non-metro for this rule. The limbs: actual HRA ₹2,40,000; rent minus 10% of basic is ₹3,00,000 − ₹48,000 = ₹2,52,000; 40% of basic is ₹1,92,000. The 40% cap binds, and exempt HRA is ₹1,92,000. Paying even higher rent would change nothing here — the cap is already the ceiling — but a restructure that raises basic would lift limb 3 directly.
Worked example 3 — rent below 10% of basic (exemption is zero)
Basic ₹4,80,000, HRA ₹2,40,000, but rent of only ₹40,000 a year — say a shared arrangement at about ₹3,300 a month. Limb 2 is ₹40,000 − ₹48,000, which is negative and floors at zero. The least of ₹2,40,000, ₹0, and ₹2,40,000 is ₹0: no exemption at all, and the entire ₹2,40,000 of HRA is taxable. This is the edge case that catches people with low rent and high basic — receiving HRA is not enough; the rent itself must exceed 10% of basic before a single rupee becomes exempt.
What to keep in order before claiming
The exemption is claimed through your employer (declare rent in the investment-proof cycle so TDS is computed on the exempt figure) or directly in your return, but the paperwork rules are the same either way: rent receipts or bank transfers evidencing actual payment, a rent agreement for larger amounts, the landlord's PAN once annual rent crosses ₹1,00,000, and TDS under §194-IB once monthly rent crosses ₹50,000. Cash rent with no trail is the classic reason an otherwise valid claim fails in scrutiny. If your employer pays no HRA at all but you still pay rent, §10(13A) does not apply — the smaller §80GG deduction is the relevant provision instead.
Because the exemption exists only under the old regime, the real question for FY 2026-27 is whether old-regime-with-HRA beats the new regime's lower slabs for your numbers. Our in-hand salary calculator computes both regimes with your rent applied, and the CTC offer comparison lets you put an old-regime structure against a new-regime one side by side. Like every tool on this site, this calculator runs entirely in your browser — your salary and rent figures are never transmitted or stored anywhere. Nothing here is tax advice: the tool shows what Rule 2A's arithmetic produces for the numbers you enter.
