Dear Sanjay,
Payment by way of a voucher is irrelevant in respect of TDS regulations. TDS shall be deducted even on credit and provisions of expenses if the threshold limit and required criteria of appropriate expenses are met. As per the TDS norms, TDS will be deducted either on credit or payment, whichever is earlier. Therefore, payment by cash, cheque, or signing voucher is irrelevant.
Thanks and Regards,
