Rhe details of your foreign supplier would not get reflected in GSTR2B because they will not be registered under gst and they would not have charged you the GST.

However, there should not be any error while putting the details in 3.1 (d). 

Pls note that the below clarification was issued by cbic:

It is noticed that the system is giving alert when the taxpayer revises the auto-populated values upward by 10% in table 3.1(d) which pertains to inward supplies attracting reverse charge. This alert is erroneous. The technical team is working to resolve the same at the earliest.

Meanwhile, the taxpayers may kindly continue to declare their correct liability in Table-3.1(d) pertaining to liability on inward supplies attracting reverse charge and proceed to file GSTR-3B

As you are an importer of services therefore you should fill 3.1(d) and 4 for payment of RCM on import of services and claim of ITC. It will not be reflected in GSTR-2B due to import of services and there will always be an error message. Proceed to pay the tax and file the return. ITC in 3B will be compared with ITC in 2B bcz it is auto-populated but you should not worry about the variance as it is practical problem. In case of import of goods there is no problem bc data is routed through ICEGATE.

Dear Sir,

Hope you are doing well !!

The system has started providing auto-populated GSTR-3B on the basis of GSTR-1 & GSTR-2B from the tax period of November 2020 onwards. In this auto-populated GSTR-3B, liability on account of inward supplies attracting reverse charge auto-populated in Table-3.1(d) is also drawn from GSTR-2B of the taxpayer for the said tax period. The values in GSTR 2B are auto populated from the GSTR-1 of the counter-parties making the supply.

It is noticed that the system is giving alert when the taxpayer revises the auto-populated values upward by 10% in table 3.1(d) which pertains to inward supplies attracting reverse charge. This alert is erroneous. The technical team is working to resolve the same at the earliest.

Meanwhile, the taxpayers may kindly continue to declare their correct liability in Table-3.1(d) pertaining to liability on inward supplies attracting reverse charge and proceed to file GSTR-3B

Most welcome

Hi

Recently GSTN introduced a facility to auto-populate system computed details in Form GSTR-3B for taxpayers (filing their Form GSTR-1 on monthly basis), from November 2020 Tax Period onwards.

CBIC directs to Ignore prompt on Liability for Inward Supplies attracting Reverse Charge in Table-3.1 (d)
