If your salary includes House Rent Allowance and you're actually paying rent, there's a tax exemption available under the old regime that's worth checking you're correctly claiming — because the exemption isn't automatic and the calculation isn't always obvious.
Here's roughly how it works. The exemption is generally the smallest of three amounts: the actual HRA you receive, your rent paid minus 10% of your basic salary, or a percentage of your basic salary that depends on whether you live in a metro city or not. Because it's the smallest of the three, the exact exemption varies quite a bit depending on your specific salary structure, your actual rent, and your city — there's no single flat number that applies to everyone.
Why this is worth actually checking rather than assuming it's handled: some salaried employees never submit rent receipts or a rental agreement to their employer's payroll team, meaning the HRA exemption never gets applied even though they're genuinely eligible for it — they end up paying more tax than necessary simply because a form wasn't submitted. Others claim it but don't realise the calculation depends on metro versus non-metro status, potentially under- or over-claiming.
The practical habit: if you receive HRA and pay rent, and you're filing under the old regime, make sure your employer has your rent receipts or rental agreement on file each year, and sanity-check the exemption being applied against the calculation above. It's a genuine, legitimate tax saving — it just requires the paperwork to actually reach the right place.
