You are saying that you would show ₹800 as food and travel reimbursement, however if you want such reimbursement should not be taxable then 1 you need to provide them with food coupons and not actual money and that too ₹50 per day and you can do that only when you have canteen and secondly every employee gets ₹40000 per year standard deduction in FY 18-19 for various allowance which includes travel allowance and ₹50000 in FY 19-20. So I don't think paying this 800 to each employee would increase a huge amount of tax burden and so it's better to deduct TDS and pay accordingly.
Hope you find the information helpful if you do please rate it 5 and provide your valuable feedback for my improvement.
Thank you
