The date which bank writes on Challan is considered as the depositing date. The Act defines that TDS should be deposited within a Week from the end of month. Deposited here means money should be transfered to the Government account till 7th in order to escape delay. If payment is made through check, it generally takes 3 days to transfer funds to the Govt. account, hence it should be deposited till 3rd or 4th so that it gets clear till 7th and you escape from delay.
