Hi,
If total value of service provided whether in India or Out side India up to the 20 Lakh in a year then GST registration is not required.
This questions will be applicable to you ONLY IF you are required to registered under GST, If registration is not required then you are exempt for GST Payment.
Export of Services are taxable at ZERO rate if the payment are received in convertible foreign currency.
In GST -Export is treated as inter-sate supply and as per the section 24 of the CGST act 2017 ,persons making any inter-sate supply shall be required to be registered under GST irrespective of the turnover . 2) Export is zero rated supply in GST ,so you can either pay IGST and take refund or you can submit LUT /BOND for export of your service . LUT- you have to submit Letter of undertaking on GSTN portal online . you can also call to GSTN help desk .
But, if you receive money in Indian Currency then it will not be treated as export of services and hence you will need to Pay GST @ 18%.
Thanks & Regards,
