Should i add the travel expense to marketing professionals salary and then cut TDS?

Hi All, We do not have a breakup in salary (like hra, travel etc) straight TDS or PT is deducted. Now travel expense is added for the marketing professionals in addition to salary. Now my query is should i add the travel expense to their salary and then cut tds or pt or add the expense it to the deducted salary. Kindly suggest. Thanks.

To my understanding, travel expenses for regular travelling on sales/marketing visits do not form part of the salary of an employee. It is the expense incurred by the company on account of Travel/Boarding & Lodging and Miscellaneous expenses for trips undertaken by its employees outside the municipal limits of the work-place. It may range from the same day return to n number of days. It can be based on actual expenses or flat allowances per day as per the travel policy of the company.
Such expenses are usually accounted in the Company's Expense Account under respective heads and ledger under these heads once the Tour vouchers are paid.

I assume, that what you mean to say is that you are paying the marketing expenses travel reimbursement in the same bank transfer or check that is given for the salary of the consent employee.
What you need to do is to separate the reimbursement of travel expenses from the rest of the salary. What you can do, in your internal working, is to compute the salary and the TDS. Thereafter, you can separately and the reimbursement to the total and transfer it to the bank account.
It would also be a good idea for you to show it in the same manner in the salary slip
