I am sure Vishal Parab, as well all readers will agree to the views expressed by Mr A K Jain, which has great clarity. It is 100 per cent correct that these reimbursements are not taxable.
However, I think Vishal has different kind of thoughts, in his mind. Everything is fine, till reimbursement is done, and no tax is deducted, by the employer. But, when IT officer goes through his bank pass book, and there are credits to his account, paid by employer as reimbursements, it is not always possible to show that these are reimbursements. IT officer may insist that this is your additional income, apart from salary, say incentives etc. This query will be raised after two/three years of actual transaction. At that time, Company’s accounts/salary department, may not cooperate the employee, and he will be in trouble.
I have an example : A field executive, working in Calcutta, offers a prestigious Gift to his client, or organizes business lunch to his client, worth Rs.10000. His HO,located in Gujarat, reimburses these expenses to his bank a/c. After 2 to 3 years, how the said employee can prove to IT officer that this credit to his a/c is not his income, but reimbursement.
