13 July 2017 I have received a bill from shipping Line
Shipping Line charges 2,00,000/-
GST @ 18% 36,000/-
Total Bill amount Rs. 2,36,000/- and certificate provided by shipping Line for non Deduction of TDS so i have not deducted TDS on shipping line bill.
now problem arises
for same amount i have a raised a debit note to a party
I have charged
For shipping Line charges 2,00,000/-
GST charges Rs. 36,000/-
Total 2,36.000/-
i sent debit note as well as Debit note of shipper to My customer , but here my customer deduct TDS on Rs. 2,00,000/- ( rs. 4,000) and paid my account Rs. 2,32,000/- , whether i should also demand to my customer to pay rs. 4,000/- ( while customer said that rs. will be deposited TDS on your PAN)
whether it is correct method.
