ITR Update – Mistakes While Filing ITR Will Prove Costly! Refund Can Get Stuck and You May Receive a Notice

ITR Filing 2026 Update: In these changing times, the process of finally filing an ITR has become much easier. However, our minor mistakes often prove to be quite costly, sometimes even resulting in financial losses. It is commonly observed that people, acting in haste, select the wrong form, while others fail to disclose their entire income.

Such actions increase the likelihood of tax refunds getting stuck. Furthermore, one may receive a tax notice or even be required to pay a penalty. If you are planning to file your ITR, it is advisable to first familiarise yourself with certain essential points—knowledge that is crucial to eliminate any confusion you may have.

The Necessity of Filing the Correct ITR Form

You might be surprised to learn that the most common and primary mistake is selecting the wrong ITR form. Did you know that a specific form is designated for every taxpayer? These include:

ITR-1:** For individuals receiving a salary and owning a single house property.
ITR-2:** For individuals or Hindu Undivided Families (HUF) without business income.
ITR-3:** For individuals with income derived from a business or profession.

Key Points Regarding ITR-4

ITR-4 is intended for those with “Presumptive Income”—that is, estimated income. This is a simplified taxation system wherein small business owners and professionals are not required to provide a detailed account of every single earning and expense.

Under this system, the government assumes that a fixed percentage of your total receipts constitutes your profit, and tax is levied solely on that assumed profit. This facility is provided under the Income Tax Act specifically for small businesses and professionals to spare them the burden of extensive accounting and auditing procedures.

Strictly Avoid Filing the Wrong Form

In this regard, remember that filing the wrong form may prompt the Tax Department to issue a notice requiring you to rectify the error. Merely filing the return is not sufficient; many people file their ITR but forget to *e-verify* it. Failing to do so is tantamount to not having submitted the return at all. After filing your ITR, it is mandatory to complete the verification process—via Aadhaar, Net Banking, or EVC—within one month (i.e., 30 days). This Mistake, Too, Can Prove Costly

Even a minor error while filing your ITR can have serious repercussions. It is crucial to accurately provide details such as your name, PAN, date of birth, mobile number, email address, and Assessment Year. Entering an incorrect Assessment Year can lead to issues like double taxation, whereas providing incorrect bank or personal details may result in your tax refund being withheld.
