Mistakes that cause notices
- Trusting pre-filled data blindly — always match it against AIS, Form 26AS and Form 16.
- Forgetting savings bank and FD interest; the bank reports it even when no TDS was deducted.
- Claiming old-regime deductions while the return is set to the new regime (or vice versa).
- Not disclosing exempt income, previous-employer salary after a job switch, or foreign shares/RSUs.
- Submitting but never e-verifying — an unverified return is invalid.
