What Is Form 15G? Eligibility, Benefits, How to Fill It & Tax Rules (2026 Guide)

Many people submit Form 15G to avoid Tax Deducted at Source (TDS) on interest earned from fixed deposits, recurring deposits, and other eligible investments. However, there is often confusion about what Form 15G actually does and whether submitting it removes the need to pay income tax.

The answer is simple: Form 15G only helps prevent TDS from being deducted if you meet the eligibility criteria. It does not make your interest income tax-free. If your total taxable income exceeds the basic exemption limit, you must still report that income while filing your income tax return.

In this guide, you’ll learn what Form 15G is, who can submit it, its eligibility rules, how to fill it correctly, the difference between Form 15G and Form 15H, and how it affects income tax return processing under Section 143(1). This will help you avoid common mistakes and ensure your return is processed smoothly.

What Is Form 15G?

Form 15G is a self-declaration submitted by eligible resident individuals and Hindu Undivided Families (HUFs) requesting banks or other financial institutions not to deduct Tax Deducted at Source (TDS) from interest income.

It can be submitted only when the taxpayer expects their total tax liability for the financial year to be nil and meets the prescribed eligibility conditions.

Submitting Form 15G does not exempt your interest income from taxation. It simply prevents TDS from being deducted in advance. If your income later becomes taxable, you are still responsible for reporting the interest income and paying any applicable tax while filing your income tax return.

Who Can Submit Form 15G?

Generally, you can submit Form 15G if you meet the following conditions:

• You are an Indian resident.
• You are an individual below 60 years of age or a Hindu Undivided Family (HUF).
• Your estimated tax liability for the financial year is nil.
• Your total income qualifies under the applicable tax rules.
• The declaration is accurate and submitted in good faith.

Senior citizens generally use Form 15H, which has different eligibility requirements.

Benefits of Form 15G

Submitting Form 15G can offer several advantages if you’re eligible:

• Prevents unnecessary TDS on eligible interest income.
• Improves cash flow by avoiding excess tax deductions.
• Reduces the need to claim TDS refunds later.
• Simplifies tax planning for eligible taxpayers.
• Helps maintain liquidity throughout the financial year.

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 to Fill Form 15G

Although the form may vary slightly between banks, the required information usually includes:

• Name of the declarant
• PAN
• Residential status
• Financial year
• Estimated total income
• Estimated interest income
• Previous Form 15G declarations, if any
• Verification and signature

Always ensure the information is accurate before submission, as incorrect declarations may attract penalties under the Income Tax Act.

Form 15G vs Form 15H

Although both Form 15G and Form 15H are self-declaration forms used to prevent Tax Deducted at Source (TDS) on eligible interest income, they are designed for different categories of taxpayers. Choosing the correct form depends primarily on your age, residential status, and eligibility under the Income Tax rules. Both forms only prevent TDS from being deducted—they do not exempt your income from taxation if tax is otherwise payable.

Eligible taxpayers	Resident individuals below 60 years of age and eligible HUFs	Resident senior citizens aged 60 years or above
Purpose	Request that no TDS be deducted on eligible interest income	Request that no TDS be deducted on eligible interest income

Common users	Salaried individuals, freelancers, and HUFs with no tax liability	Retired individuals and senior citizens with no tax liability

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.

How to Avoid Tax Demand After Submitting Form 15G

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 is a useful declaration for eligible taxpayers who want to avoid unnecessary TDS on interest income. However, it should never be confused with an exemption from income tax. Even if no TDS is deducted, you must report all taxable interest income while filing your return whenever your total income exceeds the applicable exemption limit.

Before filing your income tax return, reconcile your income with Form 26AS, the Annual Information Statement (AIS), and your bank records. Accurate reporting helps reduce the chances of adjustments during processing under Section 143(1) and ensures a smoother tax filing experience.
