TDS Provisions

 Helloooo,

If we have a bill below 20000/- in a single time and thereafter we have an aggregate amount of Rs. 50000/- in the financial year then tds should be deducted from the begining or after crossing only 50000/-

Example: Ist Bill amount - 18000/-

IInd bill amount-     18000/-

IIIrd bill amount -18000/-

Thereafter TDS should be deducted only from IIIrd bill (ie; 4000/-) or on 54000/-????? (18000*3)
