Tax experts are warning taxpayers about several commonly overlooked mistakes while filing Income Tax Returns for Assessment Year 2026–27, errors that could lead to notices, delayed refunds, or incorrect tax calculations.
Taxpayers Urged to Avoid Common Filing Pitfalls
As the Income Tax Return (ITR) filing season for Assessment Year (AY) 2026–27 gains momentum, taxpayers are being advised to pay close attention to details that often go unnoticed during the filing process.
While many filers focus on major aspects such as income declarations and deductions, experts point out that several less-discussed mistakes can result in tax notices, delayed refunds, additional tax liabilities, or compliance issues.
With the tax filing process becoming increasingly data-driven and automated, even small discrepancies can attract scrutiny from the Income Tax Department.
1. Failing to Reconcile Income with AIS and Form 26AS
One of the most common mistakes is not verifying income details against the Annual Information Statement (AIS) and Form 26AS before filing returns.
Many taxpayers rely solely on salary statements or personal records and overlook information available in these official tax documents. Differences in interest income, dividends, securities transactions, or tax deducted at source (TDS) can lead to mismatches.
Experts recommend carefully reviewing these records and reconciling any discrepancies before submitting returns.
2. Choosing the Wrong ITR Form
Selecting an incorrect ITR form remains a frequent yet often underestimated error.
Different categories of taxpayers must use specific forms depending on their income sources, business activities, capital gains, and residential status. Filing under the wrong form may result in defective return notices and additional compliance requirements.
Taxpayers are advised to review eligibility criteria carefully before choosing an ITR form.
3. Ignoring Small or Passive Income Sources
Many taxpayers unintentionally omit smaller income streams, assuming they are insignificant.
Income from savings accounts, fixed deposits, recurring deposits, dividends, freelance assignments, rental income, or overseas investments must generally be reported where applicable. Even modest amounts can trigger discrepancies if reported by financial institutions but omitted from tax returns.
Experts stress that comprehensive disclosure helps avoid future complications.
4. Incorrectly Claiming Deductions and Exemptions
Errors related to deductions and exemptions continue to be a major area of concern.
Taxpayers sometimes claim deductions without verifying eligibility or maintaining supporting documents. Others mistakenly claim benefits under provisions that may not apply under their chosen tax regime.
As tax authorities increasingly use digital verification systems, inaccurate claims may attract scrutiny or require further clarification.
5. Neglecting Verification After Filing
A surprisingly common mistake occurs after the return is submitted.
Many taxpayers assume the filing process is complete once the return is uploaded. However, returns generally need to be verified within the prescribed timeline, either electronically or through other approved methods.
Failure to verify a return can result in it being treated as invalid, effectively meaning the return has not been filed.
Why These Mistakes Matter
The Income Tax Department now relies heavily on technology, data analytics, and information-sharing mechanisms to identify inconsistencies.
As a result, errors that may have gone unnoticed in previous years are increasingly being detected automatically. This can lead to notices, delayed refund processing, reassessments, or additional compliance obligations.
Tax professionals emphasize that careful review before submission can help taxpayers avoid unnecessary complications.
Growing Importance of Accurate Tax Compliance
The increasing digitization of India’s tax ecosystem has simplified filing procedures but has also raised expectations regarding accuracy and transparency.
Tools such as AIS, Form 26AS, and pre-filled returns provide taxpayers with greater visibility into their financial information. However, taxpayers still bear responsibility for ensuring that all information submitted is complete and correct.
Experts advise reviewing all documents thoroughly and seeking professional assistance where necessary, particularly in cases involving multiple income sources, capital gains, foreign assets, or complex tax situations.
Conclusion
As taxpayers prepare to file returns for AY 2026–27, avoiding common but often overlooked mistakes can help ensure a smoother filing experience. Errors such as failing to reconcile income records, choosing the wrong ITR form, omitting minor income sources, incorrectly claiming deductions, or neglecting return verification can create avoidable complications. By taking a careful and informed approach, taxpayers can improve compliance, reduce the risk of notices, and facilitate faster processing of refunds.
