What will happen if I opt for presumptive taxation scheme (PTS) for profession but I declare the profit at lesser percentage of turnover/receipts than that mandated as per the PTS (i.e. I declare profits at a rate lesser than 50%)?
You cannot opt for PTS if you are declaring profits at a rate lesser than the mandated rate. In such case, you need to maintain the books of account and get them audited from a Chartered Accountant and based on the report of such audit, you have to declare income in the income tax return.
