Sir,
I noticed a recent order of Central tax (Order No - 02/2018- Central tax, dated 31-12-2018) about the cut off date to correct mistakes in previous periods is extended up to March 2019.
In Feb 2018 I had mistakenly entered purchase and sale turnover 2 times which was totaled wrongly because of manual calculations. And also availed input of mistakenly entered purchase along with output of sales in GSTR 3B & GSTR 1 returns.
Can I reconcile the mistake in current month return ( in DEC 2018) by adjusting those figures. i.e reducing input from current month return which was mistakenly claimed earlier. As per above notification can I correct the mistake? Please give me a advice
