All reimbursements after producing the bills are not taxable. Some companies include reimbursements as a part of CTC, i.e., cost to the company - Telephone reimbursement, uniform reimbursement, medical, petrol, etc.
Reimbursement vs. Allowance
Please note: Reimbursement is always given against producing the expense details and bills. In this case, as conveyed, it is a fixed amount and not actual. Furthermore, no bills are required to be provided. In this case, it is an allowance and not reimbursement, and hence, it is taxable.
An employer may impose a condition that the reimbursement is up to a certain limit even though the expense bills exceed that limit.
Business-Related Expenses
Additionally, these expenses must be related to the business and not to and from residence. If they are related to travel to and from residence, in that case, even though it is considered reimbursement, it will only be allowable up to Rs. 800/- per month and not more.
