I have a doubt, let me know, whether you actually paid him Rs.15,000/-(for the entire year) even before the bills were produced or is't that he produced bills only for Rs.10,000/- and was reimbursed only upto 10,000 ? My hunch is that his CTC include a component "medical exp.reimbursed to the extent of Rs.15,000/- and he so far didn't produce bills for the balance of Rs.5000. On this premise if you have not reimbursed or paid him 15000 there is no need to tax him for the unpaid 5000. In other words 'No payment No tax', which one is correct ? Even if you paid him fully Rs.15000 as a part of salary and against which he only produced Rs.10000 then exemption is not available for balance of 5000 which any how remains part of salary in which case you need not add back separately as an additional income and taxable income, IT computed accordingly.
