Should GSTR9 be filed for nil turnover?

This discussion addresses whether GSTR9 and GSTR9C are required for the financial year 2020-21 when a taxpayer has nil turnover and has already cancelled their GST registration, filing a final GSTR10 return. The consensus is that GSTR9 is generally optional for taxpayers with an aggregate annual turnover (AATO) up to Rs. 2 crore. Given the cancellation and GSTR10 filing, the GSTIN is inactive, further impacting filing requirements.
