As far as I know, what he means is that if you have an auditing firm then the date to submit your audit is 31st October.
If you own a business or a profession which has a turnover of 1 cr or 50 lakhs respectively then you need to go for auditing.
But if your income is less than that then you need to go for ITR filing which had the end date of 31st July.
Thanks for the explanation but I do not fall under those categories. I am aware of the consequences of filing an ITR late whereas this thread was meant for anyone new to this industry to understand what can happen if they use a third party like the one I used. It is better to make time and file the ITR all by themselves which I will be doing after this incident.
