(a) the Individual has not been in receipt of any House Rent Allowance from his employer specifically granted to him which qualifies for exemption under section 10(13A) of the Act;
(b) the Individual files the declaration in Form No. 10BA.
(c) The employee does not own:
(i) any residential accommodation himself or by his spouse or minor child or where such Individual is a member of a Hindu Undivided Family, by such family, at the place where he ordinarily resides or performs duties of his office or carries on his business or profession; or

(d) He will be entitled to a deduction in respect of house rent paid by him in excess of 10% of his total income, subject to a ceiling of 25% thereof or Rs. 2,000/- per month, whichever is less. The total income for working out these percentages will be computed before making any deduction under section 80GG. In other word eligibility will be least amount of the following :-
1) Rent paid minus 10 percent the adjusted total income.
2) Rs 2,000 per month.
3) 25 percent of the adjusted total income.

In such a case, no deduction will be allowed in respect of the rent paid, even if the person does not own any residential accommodation at the place where he ordinarily resides.

The adjusted total income means :-

Short Term Capital Gain of 10% category,
Deductions under sections 80C to 80U except section 80GG and income of foreign company.
Conclusion-Limit under Sec. 80GG has not kept pace with the limits under Sec. 10(13A) obviously because the limit under Sec. 10(13A) could be subject matter of revision by notification, while the limit under Sec. 80GG is stipulated in the statute itself so that an amendment to law would be required for enhancing the limit.
