Form 143 Replaces 27EQ: TCS Filing Process & Due Dates 2026

Imagine being a business owner who regularly collects Tax Collected at Source (TCS) on high-value transactions, only to discover that the familiar Form 27EQ you've been filing for years has been replaced. From Financial Year 2025-26, the Income Tax Department has introduced Form 143 as the new quarterly TCS return format, replacing Form 27EQ entirely. This change brings significant updates to the filing process, due dates, and compliance requirements that every tax collector must understand to avoid penalties.

In this comprehensive guide, you'll learn everything about Form 143—what it is, why it replaced Form 27EQ, the new quarterly filing schedule, step-by-step online filing process, and critical compliance deadlines for FY 2025-26 and AY 2026-27.

What is Form 143 and Why Did It Replace Form 27EQ?

Form 143 is the newly introduced quarterly statement for reporting Tax Collected at Source (TCS) under Section 206C of the Income Tax Act, 1961. The Central Board of Direct Taxes (CBDT) implemented this change to standardize tax reporting formats and bring TCS filing in line with the TDS return filing system that uses Form 24Q, 26Q, and 27Q.

Previously, tax collectors used Form 27EQ to report TCS deducted and deposited with the government. However, from Financial Year 2025-26 (Assessment Year 2026-27), Form 27EQ has been completely phased out and replaced by Form 143. This transition aims to improve data accuracy, enhance digital compliance tracking, and simplify the reconciliation process between TCS collected and taxes credited to collectees' Form 26AS.

The key driver behind this change is the government's push toward unified tax reporting architecture. Form 143 features enhanced data fields, better validation mechanisms, and improved integration with the Annual Information Statement (AIS) system, making it easier for taxpayers to track tax credits and for the department to monitor compliance.

Who Must File Form 143 TCS Returns?

Understanding who is liable to file Form 143 is crucial for compliance. Under Section 206C of the Income Tax Act, the following entities must collect TCS and file quarterly returns using Form 143:

Sellers of Specified Goods

Businesses engaged in the sale of specified goods such as scrap materials, minerals (excluding coal and lignite), tendu leaves, timber obtained under forest lease, timber obtained by any mode other than forest lease, alcoholic liquor for human consumption, and forest produce not being timber or tendu leaves must collect TCS at prescribed rates and file Form 143 quarterly.

Parking Lot and Toll Plaza Operators

Operators of parking lots and toll plazas who collect lease amounts exceeding Rs. 2,00,000 annually must collect TCS at 2% and report these collections through Form 143 every quarter.

E-Commerce Operators

Under Section 206C(1H), e-commerce operators facilitating sale of goods or provision of services through their digital platforms must collect TCS at 1% on the gross amount of sale or service (or 5% if the seller's PAN is not available). This applies to all e-commerce transactions and must be reported quarterly via Form 143.

Sellers Under Section 206C(1H)

From October 1, 2020, sellers whose turnover from business exceeded Rs. 10 crore in the preceding financial year must collect TCS at 0.1% on receipt of amount exceeding Rs. 50 lakh from a buyer in a financial year. These sellers must file Form 143 for all such collections.

Form 143 Filing Due Dates for FY 2025-26

One of the most significant changes with Form 143 is the quarterly filing schedule with strictly defined due dates. Missing these deadlines can result in substantial penalties, so marking these dates in your compliance calendar is essential.

These due dates align with the TDS return filing schedule, creating a unified compliance calendar for all tax withholding and collection obligations. Note that these are statutory deadlines—the Income Tax Department typically does not extend these dates except in extraordinary circumstances.

Important: The TCS collected must first be deposited to the government through challan ITNS 283 within the prescribed time (generally by the 7th of the following month), and then reported in the quarterly Form 143 return.

Step-by-Step Guide: How to File Form 143 Online

Filing Form 143 online through the Income Tax e-filing portal is now the only accepted method. Here's a detailed, step-by-step process to ensure error-free filing:

Step 1: Prepare TCS Data and Challans

Before beginning the online filing process, gather all relevant information including details of all collectees (name, PAN, amount collected), TCS challan details (BSR code, challan serial number, deposit date, amount), rate of TCS applicable under relevant sections, and the quarter for which you're filing. Ensure all TCS amounts have been deposited using Challan ITNS 283 before filing the return.

Step 2: Download Return Preparation Utility

Visit the Income Tax Department's e-filing portal at incometax.gov.in and navigate to the Downloads section. Download the latest Return Preparation Utility (RPU) for Form 143 or the Java-based utility, depending on your preference and system compatibility. The RPU is an Excel-based utility that allows offline data entry with built-in validations.

Step 3: Enter TCS Details in the Utility

Open the downloaded utility and enter your TAN (Tax Deduction and Collection Account Number) in the designated field. Fill in collectee details including PAN, name, and amount of TCS collected for each transaction. Enter challan details accurately—any mismatch between challan information and filed return will result in rejection. The utility will automatically validate PAN formats, calculate totals, and check for common errors.

Step 4: Validate and Generate the File

After entering all data, use the validation function within the utility to check for errors. Common validation checks include PAN format verification, challan number uniqueness, total TCS amount reconciliation with challan amounts, and mandatory field completion. Once validation is successful, generate the TCS file in the prescribed format (typically a .txt or .zip file).

Step 5: Login to E-Filing Portal and Upload

Login to the Income Tax e-filing portal using your TAN credentials. Navigate to e-File > File Income Tax Forms > TCS Statements. Select Form 143 from the dropdown menu and choose the relevant financial year and quarter. Upload the validated file generated from the RPU. The portal will perform additional validations upon upload.

Step 6: Submit with Digital Signature or EVC

After successful upload and validation, you must verify the return using either a Digital Signature Certificate (DSC) or Electronic Verification Code (EVC). For entities required to get their accounts audited under tax laws, DSC is mandatory. For others, EVC can be generated through Aadhaar OTP, net banking, or bank account validation. Submit the return after verification.

Step 7: Download Acknowledgement

Once submitted successfully, the portal will generate an acknowledgement with a unique Token Number. Download and save this acknowledgement as proof of filing. The collectees will be able to view the TCS credit in their Form 26AS / TDS Fetch Tool within a few days of successful filing.

For businesses managing complex tax calculations across TDS and TCS, consider using Bank Statement Analyser to reconcile your tax payments with bank transactions efficiently.

Key Differences Between Form 143 and Form 27EQ

While Form 143 serves the same fundamental purpose as Form 27EQ—reporting TCS collected and deposited—there are several important differences that tax collectors must understand:

Enhanced Data Fields

Form 143 includes additional data fields for more granular reporting, including separate columns for TCS collected under different sub-sections of Section 206C, improved collectee identification fields with email and mobile number (optional but recommended), and enhanced challan reconciliation fields that reduce mismatches.

Improved Validation Mechanism

The new form features real-time validation of PAN and TAN during data entry in the RPU, automatic cross-verification with challan details available in the OLTAS (Online Tax Accounting System), and better error messaging to help identify and correct issues before final submission. These improvements significantly reduce the rejection rate and ensure faster processing.

Integration with AIS and Form 26AS

Form 143 is designed to seamlessly integrate with the Annual Information Statement (AIS) system and reflect TCS credits in collectees' Form 26AS more quickly and accurately. This helps taxpayers verify their tax credits during ITR filing and reduces disputes related to TCS credit claims.

Mandatory Digital Filing

Unlike Form 27EQ which had provisions for paper filing in certain cases, Form 143 is exclusively digital. All tax collectors, regardless of the number of transactions, must file online through the e-filing portal.

Penalties and Consequences for Non-Compliance

The Income Tax Act prescribes strict penalties for failure to file Form 143 or filing incorrect information. Understanding these consequences is crucial for maintaining compliance:

Section 234E: Late Filing Penalty

Under Section 234E, a penalty of Rs. 200 per day is levied for every day of delay in filing the TCS return. This penalty starts from the day following the due date and continues until the return is filed. For example, if you file the Q1 return on August 15, 2025 (due date was July 31, 2025), you would incur a penalty of Rs. 200 × 15 days = Rs. 3,000.

Section 271H: Non-Filing Penalty

If you fail to file Form 143 even after receiving a notice from the Assessing Officer, a penalty under Section 271H can be imposed. This penalty ranges from a minimum of Rs. 10,000 to a maximum of Rs. 1,00,000, depending on the severity and duration of non-compliance.

Section 276BB: Prosecution

Willful failure to collect or pay TCS, or filing false TCS returns, can lead to prosecution under Section 276BB with imprisonment ranging from 3 months to 7 years, along with a fine. While prosecution is typically reserved for serious cases of tax evasion, it underscores the importance of accurate and timely compliance.

Interest on Late Deposit

Apart from return filing penalties, if TCS collected is not deposited within the prescribed time (by the 7th of the following month), interest under Section 206C(7) applies at 1% per month or part of the month from the date of collection until the date of deposit.

Common Errors to Avoid While Filing Form 143

Based on early adoption trends since Form 143's introduction, here are common mistakes tax collectors should avoid:

Incorrect PAN or TAN: Entering wrong PAN of collectees or your own TAN will cause the return to be rejected. Always verify PAN from official documents and use the PAN validation feature in the RPU.

Challan Mismatch: Ensure the challan details entered in Form 143 exactly match the details in OLTAS. Even a single-digit error in BSR code or challan serial number will cause processing issues.

Wrong TCS Rate: Applying incorrect TCS rates for different transaction types is a common error. Refer to the relevant sub-section of Section 206C to determine the correct rate. For instance, TCS on sale of motor vehicles is 1%, while TCS on scrap is 1% (for transactions above threshold).

Missing Quarterly Returns: Some collectors mistakenly believe they can file annually if their TCS volume is low. Form 143 must be filed quarterly even if you have just one transaction in that quarter. A nil return should be filed if there are no transactions.

Delayed Filing Despite Timely Deposit: Remember that depositing TCS on time doesn't exempt you from the quarterly return filing requirement. Both deposit and return filing must happen within their respective deadlines.

Special Provisions and Recent Updates for FY 2025-26

As we are in April 2026, it's important to note any recent CBDT circulars or notifications that affect Form 143 filing for the current financial year:

The Finance Act 2025 introduced certain rate changes for TCS collection. E-commerce operators under Section 206C(1H) continue to collect TCS at 1% (or 5% without PAN), with no changes announced for FY 2025-26. However, the threshold for TCS on sale of goods under Section 206C(1H) for sellers remains at Rs. 50 lakh annual receipt from a buyer, with TCS at 0.1%.

The CBDT has emphasized the importance of accurate and timely filing through recent circulars, warning that systematic non-compliance will trigger automated notices and potential audits. The department has also enhanced the TRACES (TDS Reconciliation Analysis and Correction Enabling System) portal to help tax collectors track their filing status, view pending corrections, and download consolidated reports across quarters.

Reporting for FY 2025-26: If you collected TCS during FY 2024-25 using Form 27EQ and have moved to Form 143 from FY 2025-26, ensure there's no duplication or gap in reporting during the transition period. Any corrections to FY 2024-25 returns should still be made using Form 27EQ, while all FY 2025-26 transactions must be reported only in Form 143.

Frequently Asked Questions

What is Form 143 and when did it replace Form 27EQ?

Form 143 is the new quarterly statement for Tax Collected at Source (TCS) that replaced Form 27EQ from Financial Year 2025-26 onwards. The CBDT introduced this change to align TCS reporting with TDS filing formats and improve compliance tracking. All tax collectors must now use Form 143 for reporting TCS deducted from April 1, 2025 onwards, with quarterly filing replacing the previous system.

What are the due dates for filing Form 143 TCS returns?

Form 143 must be filed quarterly with specific due dates: Q1 (April-June) by July 31, Q2 (July-September) by October 31, Q3 (October-December) by January 31, and Q4 (January-March) by May 31. These due dates align with TDS return filing schedules under Form 26Q. Late filing attracts penalties under Section 234E of Rs. 200 per day, with minimum penalty matching the TCS amount if return is not filed.

Who needs to file Form 143 TCS returns?

Any person or entity responsible for collecting tax at source under Section 206C of the Income Tax Act must file Form 143.
