The minimum-of-three rule
Your HRA exemption is the lowest of three amounts: the HRA you actually received, the rent you paid minus 10% of your basic salary, and half your basic if you live in a metro (40% elsewhere). Whichever of the three is smallest is tax-free; the rest of your HRA is taxed as normal salary.
The design has a logic to it. The first leg stops you claiming more than you were given. The second makes the exemption track your genuine rent burden — the 10% haircut assumes anyone can absorb rent up to a tenth of basic. The third caps the whole thing relative to your salary level, so an inflated rent figure cannot manufacture an outsized exemption. The calculator above shows all three legs live, so you can see exactly which one is binding you — and what would have to change for a bigger exemption.
A worked example
Take a Mumbai salary: basic ₹6,00,000 a year, HRA ₹3,00,000, rent ₹25,000 a month (₹3,00,000 a year). Leg one is ₹3,00,000. Leg two is ₹3,00,000 − ₹60,000 = ₹2,40,000. Leg three is 50% of basic = ₹3,00,000. The minimum is ₹2,40,000 — that much of the HRA is exempt, and the remaining ₹60,000 is taxed.
Notice what binds here: the rent leg. Pushing rent up by ₹1,000 a month would raise the exemption by ₹12,000 a year — while raising your actual rent by ₹12,000. Tax relief at your slab rate never outruns the rent itself, which is why renting a costlier flat “for the HRA” is arithmetic that never works. The exemption softens rent; it does not make rent profitable.
| Leg 1 — HRA received | ₹3,00,000 |
| Leg 2 — rent − 10% of basic | ₹2,40,000 |
| Leg 3 — 50% of basic | ₹3,00,000 |
| Exempt (lowest leg) | ₹2,40,000 |
Old regime only — check that first
The HRA exemption exists only in the old tax regime. The new regime — the default since FY 2023-24 — taxes your entire HRA and compensates with lower slab rates across the board. Which side wins is a real calculation, not a slogan: high rent in a metro with a large HRA component is the classic profile where the old regime still earns its keep, especially stacked with 80C and home-loan interest.
So run the sequence in order: compute your exemption here, then feed it into the income tax calculator’s old-vs-new comparison along with your other deductions. Choosing a regime because a colleague did is how people quietly donate ₹20,000–₹50,000 a year to the exchequer.
Rent receipts, landlord PAN and paying parents
The paperwork rules are simple but strictly enforced. Rent above ₹1 lakh a year (about ₹8,333/month) requires your landlord’s PAN for the employer’s records. Payments should leave a trail — bank transfer beats cash, and if you do pay cash, keep signed revenue-stamped receipts. Claiming HRA while living in your own house, or on rent never actually paid, is among the most routinely caught frauds in salary assessments, because the department cross-checks your claim against the landlord’s reported rental income.
Paying rent to your parents is entirely legal — provided it is real. The house must be theirs (not partly yours), the money must actually move every month, and they must declare it as rental income in their returns, where they get a flat 30% standard deduction on it. Done honestly, it shifts income from your slab to a parent’s often-lower one. Done as a paper entry, it is the first thing an assessing officer looks at. And if your salary has no HRA component at all, you are not out of options — Section 80GG allows a smaller deduction, capped at ₹60,000 a year.
