HRA Three-Condition Rule: Find the Binding Limit

Reviewed by CA Nikhil Gupta · Last reviewed 30 August 2026

CA Nikhil Gupta·Aug 2026·4 min readIncome Tax

The three-condition rule is a minimum test.

Actual HRA limits employer-funded exemption, the rent limb limits claims where rent is modest, and the city limb limits claims where HRA and rent are high relative to salary.

Use the HRA Exemption Calculator — Tax Year 2026-27 to apply these points to your figures.

Legal or Computational Framework

This article uses the AY 2026–27 framework for income earned in FY 2025–26 under section 10(13A) of the Income-tax Act, 1961 read with Rule 2A. For this period, and in the current official departmental material reviewed on 1 August 2026, the 50% salary limb is restricted to Mumbai, Kolkata, Delhi and Chennai; all other locations use 40%. HRA exemption is ordinarily unavailable under the default new tax regime, so regime selection is a threshold eligibility question.

Worked Example

Case A: HRA ₹1,80,000, rent limb ₹2,20,000, city limb ₹3,00,000—actual HRA binds. Case B: HRA ₹3,00,000, rent limb ₹1,90,000, city limb ₹2,40,000—rent binds. Case C: HRA ₹3,20,000, rent limb ₹3,10,000, city limb ₹2,40,000—city limb binds. Each employee needs a different explanation even though the same formula applies.

What Generic Pages Miss

  • Describing the formula without explaining which limb binds.
  • Confusing quantitative limbs with document conditions.
  • Suggesting rent should be increased solely for tax.
  • Failing to cap negative rent limb at nil.
  • Ignoring changes in variables during the year.

Practical Documentation Checklist

  • Three-limb calculation
  • Salary definition note
  • Rent and HRA period reconciliation
  • City evidence
  • Employer payroll working

Finin2min Summary

The three-condition rule is a minimum test. Actual HRA limits employer-funded exemption, the rent limb limits claims where rent is modest, and the city limb limits claims where HRA and rent are high relative to salary.

Frequently Asked Questions

Why is the lowest amount used? â–¼
Rule 2A is designed to exempt only the portion supported simultaneously by allowance, rent burden and salary/city limits.
What if two limbs are equal? â–¼
The equal lowest amount is the exemption; note both as binding if useful.
Can I optimise by increasing HRA in CTC? â–¼
A larger HRA helps only if actual HRA is the binding limb and genuine rent supports a higher exemption.
Can rent paid to family change the binding limb? â–¼
Only genuine, enforceable and evidenced rent can be used; the recipient should report rental income.
Why calculate period-wise? â–¼
Because the binding limb can change after a salary revision, rent increase or relocation.
Does the rule apply in the new regime? â–¼
The HRA exemption is ordinarily not available there, so the three-limb computation is generally relevant to the old regime.
