Weekly update dated 15.02.2020 issued by CBIC and relevant portion is reproduced below
• The GST laws, as of now, permit interest calculation on delayed GST payment on the basis of gross tax liability. This position has been upheld in the Telangana High Court’s decision dated 18.04.2019 = 2019 (4) TMI 1319 - TELANGANA AND ANDHRA PRADESH HIGH COURT
• In spite of this position of law and Telangana High Court’s order, the Central Government and several State Governments, on the recommendations of GST Council in its 31st Meeting, amended their respective CGST/SGST Acts to charge interest on delayed GST payment on the basis of net tax liability. Such amendment will be made prospectively from a date yet to be notified.
Hope this will help in the matter.
Thanks
