I have 0 taxable income after claiming all deductions like Home loan/Medical tax exemption/Section 80U etc I want to claim LTA. however i dont know a) Is this taxed seperately or added to the gross income and tax applied on that? b) Can I claim it every year if i have 0 taxable income even after claiming LTA? c) I understand that i dont need to show proofs to my employer however i need to show proofs to the tax authorities- what i want to know if I have 0 taxable income every time i claim LTA, do i need to show this proofs or not?
