Pre-filled tax return details may contain errors despite automated reporting.
AIS and Form 26AS verification have become extremely important this year.
Wrong tax regime or incorrect ITR form selection can increase tax liability.
The ITR filing process for Assessment Year 2026-27 has now started. The Income Tax Department has already made forms such as ITR-1, ITR-2, and ITR-4 available on the official portal. This year’s tax filing season is more important because it comes just before the government plans major tax law changes under the new Income Tax Act framework in the coming years.
The tax department collects financial data directly from employers, banks, stock brokers, mutual fund companies, and several other institutions. Many details automatically appear in tax returns even before a person starts filing.
While this saves time, pre-filled data may sometimes contain mistakes. Even a small mismatch can cause refund delays, tax notices, or extra tax demands later. A careful review before final submission has become extremely important this year.
Basic details such as full name, PAN number, Aadhaar status, date of birth, and address automatically appear in the return form. Many taxpayers ignore this section because the information looks simple.
However, even a small mismatch between PAN and Aadhaar records can create technical errors during submission. Erroneous contact details can also create problems if the department later sends refund updates or tax notices.

Salary income details usually come directly from employer records filed with the tax department. However, mistakes can happen, especially when a person has changed jobs during the financial year or worked for more than one employer.
Tax experts recently warned that salary mismatches are one of the biggest reasons behind unexpected tax demand notices during AY 2026-27 filing.
Tax Deducted at Source (TDS) shows in Form 26AS. This section includes tax deducted on salary, bank interest, rent payments, professional income, and other payments. If any TDS entry is not correct, the refund amounts may become smaller than expected.
In some cases, tax liability may suddenly increase even after tax payment has already been made. The Income Tax Department has asked taxpayers to carefully compare Form 26AS details before final submission.
The Annual Information Statement, known as AIS, has become one of the strongest compliance tools used by tax authorities. This statement records bank interest, dividend income, stock market transactions, foreign money transfers, credit card expenses, property deals, and several other financial activities. Tax experts now say checking AIS is no longer optional because mismatched records can trigger automatic tax notices.
Refund processing depends completely on the correct bank account details. If account numbers, IFSC codes, or account validation status contain errors, the refund credit may face a major delay. Many taxpayers focus only on tax calculation and forget this section, but refund problems often begin with wrong banking details.
Interest earned from savings accounts, fixed deposits, recurring deposits, and post office schemes now reaches tax authorities directly through financial institutions. Many people wrongly believe small interest income does not require reporting.
This often creates mismatch notices later because banks already share these records with the department. Bank statements should always match the details shown in the tax return.
Stock market profits, mutual fund redemption details, crypto transactions, and property sale details now increasingly appear automatically in pre-filled tax returns. The government has recently increased its focus on capital gains reporting after tighter scrutiny rules came into effect. Even a small mistake in purchase value, sale amount, or profit calculation may invite reassessment later.
Taxpayers who choose the old tax regime often claim deductions under Section 80C, Section 80D, home loan interest, education loan benefits, and HRA exemption. These deductions do not always appear correctly in pre-filled returns. Many taxpayers wrongly assume every deduction automatically reflects in the system. Independent verification remains necessary before submission.
The new tax regime continues as the default option for AY 2026-27. The old tax regime remains available, but only after proper selection during filing. This year, tax slab changes under the Financial Year 2025-26 have made tax regime comparison more important than before. Wrong selection can significantly increase tax liability even when income details remain correct.
Many taxpayers still select the wrong return form. The tax department has already activated ITR-1, ITR-2, ITR-3, and ITR-4 utilities for AY 2026-27. Filing under the wrong category may result in defective return notices.
At the same time, CBDT recently introduced fresh scrutiny guidelines for the Financial Year 2026-27. This means high-risk or incorrect filings may face stricter examination by tax authorities.

Technology has made tax filing faster and easier, but it has also made the entire process more sensitive to errors. Pre-filled information may look correct at first glance, but every section still needs manual review.
For AY 2026-27, salary details, AIS records, TDS credits, bank account details, deductions, capital gains, and tax regime selection require extra attention.
The filing deadline for most non-audit taxpayers remains 31 July 2026. Fast filing has value, but accurate filing matters far more. Even a small mismatch can create unnecessary trouble later.
Has the ITR filing for AY 2026-27 started?
Yes, the Income Tax Department has enabled filing for major ITR forms on the official portal, allowing eligible taxpayers to begin submitting their returns.
Is pre-filled data always accurate in ITR forms?
No, taxpayers must carefully verify all pre-filled details, as errors or missing information may appear and can affect the accuracy of tax filings.
Why is AIS important during ITR filing?
AIS provides details of major financial transactions, income sources, and tax-related information that tax authorities use for verification and compliance checks.
Can wrong bank details delay tax refunds?
Yes, incorrect bank account details, failed validation, or inactive accounts can delay refund processing and may require additional verification steps.
What is the last date to file ITR for AY 2026-27?
For most non-audit taxpayers, the deadline remains 31 July 2026, while taxpayers requiring an audit may have different filing timelines.
