TCS responsibility on Foreign Remittance

H (D) (50 Points)

22 November 2021  

 Foreign Remittance being done by me under LRS in installments for fees of my son studying in US, recently exceeded Rs. 7 Lakhs when I  made last payment of Rs. 1.5 Lakhs. However,  no TCS was deducted though I had declared the total amount paid so far in USD, while processing the payment through a third party payment service. 

Is it so because I had declared my PAN in this transaction and since I am already having regular TDS being done from my salary, hence TCS was not applied

OR

I am supposed to calculate 5% TCS and pay it online on IT Department's website myself.
