Change of bill date in gstr1

This discussion addresses an issue where GSTR1 bill dates were incorrectly entered, potentially misclassifying invoices between financial years. While direct rectification of these past dates is no longer possible due to missed deadlines, the recipient can still claim Input Tax Credit (ITC). However, this may cause a mismatch with GSTR 2A and 2B. The law allows for ITC to be carried forward indefinitely if unutilised, but there are time limits for claiming it. The query also explores the possibility of rectifying or declaring these errors in GSTR 9C for the relevant financial year.
