What Is a Quarterly TCS Return?

A quarterly TCS return is a statement filed by a person who collects Tax Collected at Source (TCS). It tells the Income Tax Department how much tax was collected from buyers during a particular quarter and how much was deposited with the government.

For example, imagine a business selling scrap to a buyer and collecting TCS on the sale. The business must deposit the collected tax with the government and report the collection through the applicable quarterly TCS statement.

This statement helps the government keep track of the tax collected and helps buyers receive credit for the tax collected from them.

Which Form Is Used for Quarterly TCS Return Filing Now?

Form 143 is the current form for quarterly TCS return filing from 1 April 2026. It replaces Form 27EQ, which was used under the Income-tax Act, 1961.

The form number changed because the Income-tax Act, 2025 and Income-tax Rules, 2026 introduced a revised system of forms and provisions.

Important: Form 27EQ remains relevant for understanding earlier tax periods. For tax periods covered by the new framework from 1 April 2026, use Form 143 and follow the applicable filing instructions.

What Is the Purpose of Filing a Quarterly TCS Return?

The main purpose of filing a quarterly TCS return is to report the tax collected from buyers and deposited with the government.

Its key purposes are:

• Reporting tax collected: It provides details of TCS collected during the quarter.
• Confirming tax payment: It reports the tax deposited with the government.
• Maintaining tax records: It helps the Income Tax Department match the tax collected with the payment records.
• Helping buyers claim tax credit: The reported TCS can be reflected in the buyer's tax records and used as credit against the buyer's final tax liability, subject to applicable rules.
• Meeting legal requirements: It helps the collector comply with the applicable tax filing requirements.

Who Is Required to File a Quarterly TCS Return?

A person or business responsible for collecting TCS on transactions covered by the applicable income-tax provisions must file the quarterly TCS statement.

Some common examples include:

• Sellers of specified goods: Businesses collecting TCS on applicable sales of scrap, alcoholic liquor, timber and other specified goods.
• Sellers of specified high-value goods: Sellers collecting TCS on transactions covered by the applicable provisions.
• Persons managing specified leases or licences: Persons collecting TCS on applicable parking lots, toll plazas, mines or quarries.
• Authorised dealers: Dealers collecting TCS on specified overseas remittances.
• Overseas tour package sellers: Sellers responsible for collecting TCS on applicable overseas tour packages.
• Other notified collectors: Persons responsible for collecting TCS on other transactions covered by law.

The exact requirement depends on the type of transaction, the collector's role and any applicable exemptions.

Is TCS Return Filing Compulsory for Every Business?

No, TCS return filing is not compulsory for every business.

It applies when a person is legally required to collect TCS on a covered transaction. A business that does not fall under the applicable TCS provisions does not have to file a TCS return merely because it is operating a business.

However, a person who is required to collect TCS should not ignore the filing requirement simply because the amount collected during a quarter is small. The applicable rules must be checked.

What Information Is Included in Form 143?

Form 143 contains information about the tax collector, the tax collected, the payment made to the government and the buyers from whom TCS was collected.

The form broadly contains the following details:
