Form 16 alone may miss interest, dividends, and capital gains
Cross-check Form 26AS, AIS, and investment statements before filing
Early ITR filing can trigger income mismatches and refund delays
Wait for updated tax records before submitting your return
With Form 16 usually arriving by mid-June, salaried taxpayers are beginning to prepare their ITRs for AY 2026–27. But filing too quickly can create problems if taxpayers rely only on Form 16 and do not cross-check Form 26AS, Annual Information Statement (AIS), bank interest, dividend income, and capital gains statements. The story will explain why early-filing mistakes can lead to mismatches, revised returns, refund delays, or tax notices. It will be useful for salaried taxpayers, investors, and anyone with income beyond salary.
Form 16 Is Important, But It Is Not The Full Picture
Form 16 is something most salaried employees look forward to receiving every year, and understandably so. It tells you how much your employer paid you and how much tax was deducted on your behalf. But treating it as the final word before filing your Income Tax Return (ITR) is where many taxpayers go wrong.
The reality is that most people have income coming in from more than one place. Your savings account earns interest. You may have received dividends on shares or mutual funds. “Maybe you sold some stocks or redeemed a few mutual fund units during the year, or you have a rental property, or you did some freelance work on the side. None of that shows up in Form 16, because your employer simply has no way of knowing about it. If you file based on Form 16 alone, you are almost certainly under-reporting your income, even if unintentionally,” says Aarjav Jain, executive director and Non-Resident Indian (NRI) tax expert, Dinesh Aarjav and Associates Chartered Accountants.
Cross-Check Form 26AS, AIS, And Investment Statements
Taxpayers must ascertain that all Form 16 Tax Deducted at Source (TDS) entries show up in Form 26AS. Next, they must ensure AIS contains interest income, dividend income, securities transactions, mutual fund redemptions, and any other reportable transactions. “Bank statements must show interest on savings and fixed deposits. The investment broker and mutual fund statements must show capital gains and losses. Any discrepancies must be rectified prior to the form submission,” says Sandeep Bhalla, partner, Dhruva Advisors.
Filing Too Early Can Create Mismatches
There is also no real benefit to rushing through your filing the moment Form 16 lands in your inbox. TDS entries from banks, companies, and other deductors typically get updated in Form 26AS and AIS only by mid-June, after they have submitted their quarterly TDS returns. “The ITR utilities on the portal also tend to get their final updates around the same time. If you file before all of this has settled, your return may not match what the department's records show,” says Jain.
“If taxpayers file their returns before such information is fully reflected, there could be mismatches between the income reported in the return and the information available with the tax department,” says Bhalla.
The smarter move is to wait, collect everything, and go through AIS, TIS, and Form 26AS carefully before you hit submit. “If something looks off, get it sorted first. A few extra days of patience at this stage is far less painful than dealing with the fallout of a return that needs to be corrected after the fact,” says Jain.
