Form 15G and Tax Return Processing Guide

Many taxpayers submit Form 15G to prevent Tax Deducted at Source (TDS) on interest earned from fixed deposits and other eligible investments. However, submitting Form 15G does not exempt that income from taxation or remove the requirement to report it in an income tax return.

During processing under Section 143(1) of the Income Tax Act, the Income Tax Department cross-verifies information reported by banks through sources such as the Annual Information Statement (AIS) and Form 26AS.

Any mismatch between the income reported in your return and the information available with the department can lead to adjustments, additional tax liability, or a tax demand.

In this guide, you’ll learn how Form 15G affects Section 143(1) processing, when tax demands may arise, and the steps you can take to report interest income correctly and avoid common filing mistakes.

Submitting Form 15G only prevents TDS deduction on eligible interest income. It does not exempt that income from taxation. If your total taxable income exceeds the exemption limit, you must report all interest income in your income tax return. During processing under Section 143(1), the Income Tax Department verifies your return with AIS, Form 26AS, and bank records. 

What Does Form 15G Do?

Form 15G is a self-declaration submitted by eligible resident individuals or Hindu Undivided Families (HUFs) requesting that banks or financial institutions not deduct TDS on eligible interest income.

To submit the declaration legally, the following conditions should generally apply:

• The estimated tax liability for the financial year is nil.
• The applicant qualifies under the prescribed eligibility criteria.
• The declaration is submitted truthfully based on the expected annual income.

Senior citizens generally submit Form 15H, which serves a similar purpose but follows separate eligibility rules.

Providing incorrect information in Form 15G can have legal consequences because it is treated as an official declaration made to the tax authorities.

How Return Processing Works

After an income tax return is filed, processing under 143 (1) of income tax act begins automatically.

The Income Tax Department compares the information reported in your return with data received from:

• Form 26AS
• Annual Information Statement (AIS)
• Banks and financial institutions
• Other third-party reporting sources

If any discrepancy exists between your reported income and the information available with the department, adjustments may be made during processing.

Scenario 1: Interest Income Was Not Reported

A common issue occurs when taxpayers submit Form 15G but forget to disclose the interest income while filing their return.

Although TDS was not deducted, the income itself remains taxable whenever the total annual income exceeds the applicable exemption limit.

Since banks report this information directly, the system can identify the omission and calculate additional tax where applicable.

Scenario 2: Income Exceeded the Exemption Limit

Sometimes taxpayers submit Form 15G expecting their income to remain below the taxable threshold, but their total earnings increase during the financial year due to salary increments, investment returns, or profits from a new venture, including one of these unique business ideas.

Income may include:

• Salary
• Interest earnings
• Rental income
• Capital gains
• Business income
• Other taxable receipts

If the combined income becomes taxable, the declaration no longer reflects the actual financial position. During processing under 143 (1) of income tax act, tax liability is recalculated and applicable interest may also be charged for delayed payment.

Scenario 3: Everything Matches Correctly

When Form 15G is submitted correctly, all interest income is disclosed in the return, and the taxpayer remains eligible for the declaration, return processing generally concludes without any adjustment.

The department’s records match the filed return, allowing the intimation to be issued without additional tax demand.

Checklist Before Filing Your Return

Before submitting your income tax return, take a few simple steps:

• Download Form 26AS and the Annual Information Statement.
• Verify interest reported by every bank.
• Include all interest income, even where no TDS was deducted.
• Calculate total taxable income accurately.
• Pay any outstanding self-assessment tax before filing, if applicable.

These checks significantly reduce the likelihood of receiving processing adjustments.

What If You Receive a Tax Demand?

If processing under 143 (1) of income tax act results in a tax demand, carefully review the reason before responding.

If the demand is correct:

• Pay the outstanding amount within the prescribed deadline.
• File a revised return if permitted.

If the demand appears incorrect:

• Compare your return with Form 26AS and AIS.
• Collect supporting documents.
• Submit a rectification request under Section 154 with appropriate evidence.

Responding within the specified timeline helps prevent unnecessary complications.

Final Thoughts on Form 15G and Tax Return Processing

Form 15G remains an effective tax-saving declaration for eligible taxpayers, but it should never be viewed as a substitute for accurate income reporting. Every source of income, including bank interest, must still be disclosed while filing an income tax return. 

Since processing under 143 (1) of income tax act relies on information received from multiple reporting sources, even minor reporting errors can trigger tax demands or delays. Careful reconciliation before filing helps ensure compliance, reduces processing issues, and supports a smoother tax filing experience.
