Will GST Liability be auto-calculated in GSTR-3B from GSTR-1 and 2A by GST portal ?

Will GST Liability be auto-calculated in GSTR-3B from GSTR-1 and 2A by GST portal ?

There is some confusion due to the change in GST Portal in regard to auto-population in GSTR-3B that
  1. GSTR-3B will be fully auto-populated.
  2. GST liability will be automatically calculated by the GST portal. We'll have to pay it.
Please note that No figures are being auto-populated in GSTR-3B.

A separate statement is being provided by the GST portal in which 
1. outward liability is populated from GSTR-1.
2. ITC from GSTR-2B.

Still, we will have to fill each and every Table in GSTR-3B and liability has to be calculated manually. 
Many tables still to be filled manually and will not be auto-populated i.e. RCM Figures, ineligible ITC, exempt/nil rated/ composition purchase etc.


ITC will be different from auto-populated ITC figures this year at least as
  • Till August, we have taken ITC as per books (as Govt has allowed to take in full).
  • We have been taking 5%/10% excess credit than GSTR-2A.
In the above scenarios, if we take ITC as per GSTR-2B, we will end up taking excess ITC than allowed (Suppliers are still filing their GSTR-1 late).

You'll still need to reconcile books with GSTR-2A/2B before filing GSTR-3B. In my opinion, we may start taking ITC as per GSTR-2B from the next financial year after due analysis.

Alert: Availing excess ITC attracts interest @ 24% along with other legal liabilities. 

Note: GSTR-2A is now to be checked on the 14th morning (GSTR-1 due date is 11th). I suggest starting using GSTR-2B for easy book-keeping.
