ITR Filing and Verification: How the Income Tax Department Spots Mismatches
Filing your income tax return (ITR) is just the first step.
After you file, you need to e-verify it so the Income Tax Department can process it.
The department checks your return for errors, matches the information you provided with their records, and then processes it.
If everything matches, you might get a refund or be told you owe no additional tax.
If there are mismatches, you might get a notice asking for more information.
Filing early can help get your refund faster, but small mistakes can still lead to scrutiny.
The key is to make sure all your details match the department's records.
ITR must be e-verified to be processed by the Income Tax Department.
The CPC in Bangalore checks for errors, correct forms, and mandatory schedules.
Data validation compares income, TDS, and deductions with Form 26AS, AIS, and TIS.
An Intimation under Section 143(1) is issued after processing, showing tax calculations and refunds.
Early filing can help get refunds sooner, but small mismatches can still trigger scrutiny.
