If I am not wrong, in 44AD when your profit becomes less than 6/8%, one needs to opt out from 44AD and move to 44AB for the next 5 years with the 5-year audit.
But is there any relaxation regarding the Audit rule if the person is a senior citizen and/or if someone is moving from the old regime to the new tax regime?
Yes, your understanding is correct. If someone opts for the presumptive taxation scheme for their business under section 44AD, they need to continue with the scheme for 5 years. In case they opt out, they have to undergo a tax audit for 5 years including the year in which they opt out.
No, there’s no exception available to this rule even if one is a senior citizen. Moreover, the choice of regime does not affect the audit applicability as well.
The applicability of a tax audit depends on your turnover and not profits or losses. In case of stock trading where 100% of the transactions are digital, tax audit is required only if your turnover exceeds ₹10Cr.
As far as the presumptive taxation scheme (44AD) is concerned, you can opt for it if the turnover is below ₹3Cr. If you do not opt-out for the next 5 years, tax audit won’t be necessary.
