Income tax rebate on hra

I think you cannot pay rent to yourself as you are the co-owner. Since you are the co-owner, it will be treated as self occupied property to the extent of your share. Alternatively, if you let out, rental income to the extent of your share is taxable income for you subject to allowable deductions. Any other view is welcome.

Well I think if you are able to elaborate that you are also using the part not owned by you or if you have occupied the whole house yau are supposed to pay rent as your father is also co owner.

But I think what matters is that you are able to elaborate and rent paid is justified. also keep section 40 A (2) in mind
