Golden words.Except for a few individuals, most of us are not experts when it comes to taxes. Therefore, we can only provide advice, but it is advisable to consult a CA. What you have done is already in the past, but now it's crucial to prepare for the future and take measures to prevent such incidents from occurring again.
One has to take action at least today and get professional help when required. Consulting a CA on a forum won’t be enough. Better to get help and file taxes showing appropriate income.
Don’t just depend on AIS and 10 lakhs spend. We get notice even for a small amount. Better to always spend below income. Otherwise be ready for an answer. It takes several years to receive notice.
