What reasons can lead to an income tax notice despite meeting ITR filing deadline?

Filing an income tax return (ITR) before the July 31, 2026, deadline does not necessarily mean that a taxpayer will not receive an income tax notice. According to The Economic Times, several factors can trigger a notice despite timely filing. They include income mismatches, unreported interest income, TDS/TCS mismatches, high-value financial transactions and capital gains discrepancies.
