As per the provisions of 194C if one bill payment exceeds RS 30000 or RS 100000 in a financial year from one single party then tds should be deducted. Suppose if payment of 28000 is made to Mr A and Payment of RS 35000 to Mr B then as per the provisions TDs is to be deducted only on Mr B payment since it exceeded the limit. However, if both the payments is made to Mr A then TDS on both payments to be deducted. Once TDs has been deducted then even if the billing is of RS 5000 it will be deducted for that relevant financial year.
