Paying rent does not by itself prove that the old tax regime produces lower tax. First calculate the HRA exemption that is actually eligible, then compare complete tax under both regimes for the same period.
HRA mechanics
Subject to Section 10(13A), Rule 2A and the applicable conditions, the exemption is generally the lowest of:
- actual HRA received;
- rent paid minus 10% of salary for this purpose; and
- 50% of salary for the specified metro cities or 40% elsewhere.
The result is not simply rent paid, and the full HRA component is not automatically exempt. Documentation and the underlying tenancy must be genuine.
Regime comparison
HRA exemption is associated with the old-regime calculation. But the regime result also depends on total income, other eligible deductions, special-rate income and the applicable year. A large rent payment can still produce a limited exemption if salary or HRA received constrains the formula.
NiyamFin's current calculators model FY 2025-26 / AY 2026-27. They do not establish a universal rent threshold at which one regime wins.
Illustrative mechanics
Suppose annual HRA received is ₹3,00,000, relevant salary is ₹6,00,000 and annual rent is ₹3,60,000 in a specified metro. The three figures are ₹3,00,000, ₹3,00,000 and ₹3,00,000, so the illustrative exemption is ₹3,00,000. This explains the formula only; it is not a regime recommendation or promised saving.
Common mistakes
- Treating monthly rent as the exemption.
- Applying the metro percentage to cities outside the statutory list.
- Assuming an HRA exemption guarantees the old regime is lower.
- Counting documentation submitted for payroll as proof of final tax treatment.
- Mixing calculator values from different periods.
Use the HRA Calculator, then enter the eligible result into the New vs Old Tax Regime Calculator.
