How does GSTR-1A Works?

Let us understand how GSTR-1A works with the help of an example –

Rahul buys 50 pencils costing Rs.100 (Rs.2 per pencil) from Tarun Stationery.
Tarun stationery made a mistake and entered Rs.10 instead of Rs.100 as cost of pencils in GSTR-1.
The data from GSTR-1 flows into Rahul’s GSTR-2A
Rahul corrected the error and put Rs.100 (Correct amount) in the place of Rs.10 (Wrong amount).
The corrected error reflects in Tarun stationery GSTR-1A.
Tarun stationery got the option to either accept or reject the changes made by Rahul. When Tarun stationery accepts the correction, GSTR-1A of Tarun stationery automatically gets updated.
