Salary paid in two payments to avoid tds

I have a small company with less than ten employees. Lately, they have been asking me to pay them in two transactions, such that their payslip will show an income less than taxable slab. Rest of their salary to be paid as allowances like shift allowance etc, which is to be transactioned at a later date. They want to avoid TDS. Is this possible? Can experts please advise. I really appreciate your valuable inputs and expert insights. Thanks for your time.
