Many of the GST users getting error as ” Checksum Validation : Failed ” while offsetting liability ..in GSTR 3B filing. This is error from GST portal only and no need to panic. I have checked with GSTN help desk who claim team is working on this issue and it will be fixed soon. Generally this happens on the day when you make online payment and try to do Offset liability next day or else wait for GSTN team to fix the error.
Like this there are many errors which GSTN throws up specially during peak filing season. It is always advisable to plan all your GST filing activities 2 days in advance to avoid wasting of more time during last minute.
