Common ITR filing mistakes to avoid

Most filing problems are avoidable with a short pre-submit check. Here are the mistakes that most often cost salaried taxpayers a refund — or a notice.

The mistakes to watch for

  • Choosing the wrong regime — staying on the payroll default instead of comparing
  • Leaving out AIS income — interest, dividends or share sales the department already sees
  • Picking the wrong ITR form for your income sources
  • Missing deductions you are entitled to — 80C top-ups, 80CCD(1B), 80D for parents
  • Not combining multiple Form 16s after a job change
  • Wrong bank details, so a refund cannot be credited
  • Forgetting to e-verify within the window — the return is then not valid

A two-minute pre-submit check

Before you hit submit: confirm the regime is the cheaper one for your numbers, confirm every AIS income is included, confirm your deductions are claimed with proof in hand, confirm the form and bank details are right — then file and e-verify.

Most notices are about omission, not evasion

The single biggest avoidable mistake is leaving out income that sits in your AIS. Reconcile first, and the most common notice trigger disappears.

Catch the costly ones first

DrishtiTax checks your regime choice and surfaces missed deductions from your Form 16, so the mistakes that actually cost money are caught before you file. Filing and e-verification stay on the income-tax portal.
