HRA Exemption Calculator

How the HRA exemption is actually calculated

House rent allowance is a normal part of your salary and is taxable by default. Section 10(13A) of the Income Tax Act carves out an exemption, but only up to the smallest of three limbs. Missing that word is the single most common mistake: people assume the whole allowance is tax free, or that the exemption equals the rent they pay. It is neither. The three limbs are the HRA actually received, the rent paid minus 10% of basic salary plus dearness allowance, and 50% of basic + DA if you live in Delhi, Mumbai, Kolkata or Chennai (40% everywhere else).

Everything is computed on the salary and rent for the period you actually paid rent. This calculator works monthly and then annualises, which is what payroll teams do when your rent or city changes mid-year. If you moved from Pune to Mumbai in October, run the tool twice — once for each block of months — and add the two exempt figures.

Worked example: ₹50,000 basic, ₹20,000 HRA, ₹18,000 rent in Pune

Pune is not one of the four metros, so the third limb uses 40%. Limb one is the HRA received: ₹20,000 a month. Limb two is rent minus 10% of basic + DA: ₹18,000 − ₹5,000 = ₹13,000. Limb three is 40% of ₹50,000 = ₹20,000. The smallest is ₹13,000, so ₹13,000 a month is exempt — ₹1,56,000 for the year. The taxable slice is ₹20,000 − ₹13,000 = ₹7,000 a month, or ₹84,000 a year, which gets added to your salary income.

Move the same person to Mumbai and the third limb becomes 50% of ₹50,000 = ₹25,000, but the rent limb is still ₹13,000, so nothing changes. The metro percentage only matters when it is the binding limb — usually when rent is high relative to basic pay.

Reading the binding limb

The limb that binds tells you what to do about it. If the rent limb binds, your exemption rises rupee for rupee with rent, so a genuine rent increase or a correctly documented rent to a parent directly increases the exemption. If the 50%/40% limb binds, extra rent buys you nothing more — your basic pay is the constraint, and only a salary restructure (a higher basic component) would help. If the actual HRA limb binds, you are being paid less allowance than the law would let you exempt; ask HR whether HRA can be a larger share of the same CTC.

When the exemption comes out as zero

If your rent is not more than 10% of basic + DA, the second limb is zero or negative and no HRA is exempt at all. At ₹50,000 basic that threshold is ₹5,000 a month: paying ₹4,500 rent produces exactly nothing. The same happens if you receive no HRA component — the law cannot exempt an allowance you were never paid. In that situation, salaried people with no HRA can look at Section 80GG instead, which allows a much smaller deduction subject to its own conditions.

Rent-to-parents compliance checklist

Paying rent to a parent is legal and routinely accepted, but it is also one of the most audited claims. Keep five things: (1) your parents genuinely own the property, ideally shown on a tax receipt or ownership document; (2) a written rent agreement in your name; (3) monthly bank transfers, never cash and never a lump sum in March; (4) rent receipts; and (5) your parents declaring the rent as income from house property in their own return, where a 30% standard deduction and their own slab apply. If a parent is in a lower slab or below the exemption limit, the family pays less tax overall — that is the legitimate benefit. Rent paid to a spouse is a different matter and is generally rejected.

Above ₹1,00,000 of rent in a financial year, roughly ₹8,334 a month, you must give your employer the landlord's PAN in Form 12BB. Very high rent can also trigger TDS obligations on you as the tenant under Section 194-IB — currently where monthly rent exceeds ₹50,000.

Old regime or new regime?

Since FY 2023-24 the new tax regime is the default, and it disallows HRA exemption completely along with 80C, 80D and most other deductions. The trade is lower slab rates plus a standard deduction. For a metro renter whose exemption runs into lakhs, the old regime frequently still wins; for someone with modest rent and few investments, the new regime usually wins. Salaried taxpayers can switch each year while filing, so compute both before you lock the declaration your employer uses for TDS.

Limits of this calculator

This tool models the standard Section 10(13A) computation for a single continuous period at one salary and one city type. It does not handle mid-year changes automatically, perquisites, arrears, or the interaction between HRA and a home loan claim (which is allowed in specific fact patterns, such as your own house being let out or in another city). It is an estimate for planning and for checking your payroll figure — not tax advice. For anything unusual, a chartered accountant should see your Form 16 and rent documents.
