How to File a TDS Return Online in India: Forms, Process and Due Dates

Tax Deducted at Source (TDS) is a mechanism through which the Indian government collects income tax at the point of income generation. Every entity that deducts TDS, whether an employer, a business, or any other deductor, must file a TDS return each quarter to report the deductions made and the amounts deposited with the government. Filing accurate and timely TDS returns is not just a compliance obligation; it directly affects the tax credits available to deductees when they file their own income tax returns.

With the enactment of the Income Tax Act 2025 and the corresponding Income Tax Rules 2026, the TDS return filing framework has undergone significant changes effective April 1, 2026. This guide walks you through the updated forms, the step-by-step filing process on the TRACES portal, quarterly due dates, and the penalties for non-compliance.

TDS Return Forms: Old and New

Prior to April 1, 2026, TDS returns were filed using a well-established set of forms: Form 24Q for salary TDS, Form 26Q for TDS on non-salary payments to residents, Form 27Q for TDS on payments to non-residents, and Form 27EQ for Tax Collected at Source (TCS). These forms continue to apply for all transactions that occurred up to March 31, 2026.

From April 1, 2026, a new set of forms has replaced the legacy ones under the Finance Bill 2026 framework. The mapping is as follows: Form 138 replaces Form 24Q (salary TDS), Form 140 replaces Form 26Q (non-salary payments to residents), Form 144 replaces Form 27Q (non-salary payments to non-residents), and Form 143 replaces Form 27EQ (TCS). Deductors filing returns for FY 2026-27 onward must use these new form numbers. It is important to note that if you are filing a correction or revised return for a period before April 1, 2026, you should still use the old form numbers.

Who Must File TDS Returns

Any person or entity that has been allotted a Tax Deduction and Collection Account Number (TAN) and has deducted or collected tax at source during a quarter is required to file a TDS/TCS return. This includes employers deducting TDS on salaries, businesses deducting TDS on payments such as professional fees, rent, interest, and contract payments, government offices, banks, and any other deductor. Even startups in their early stages must comply once they begin making payments that attract TDS obligations. The obligation to file exists even if the deductor has nil deductions in a quarter, though in practice many deductors choose not to file nil returns unless specifically required by their assessing officer.

Quarterly Due Dates for FY 2026-27

TDS returns must be filed on a quarterly basis. The due dates for FY 2026-27 are as follows. For Q1 (April to June 2026), the return must be filed by July 31, 2026. For Q2 (July to September 2026), the deadline is October 31, 2026. For Q3 (October to December 2026), the return is due by January 31, 2027. For Q4 (January to March 2027), the filing deadline is May 31, 2027.

Missing these deadlines triggers automatic penalties, so it is critical to maintain a compliance calendar. Businesses that also handle annual MCA compliance should coordinate their TDS filing schedule alongside ROC deadlines to avoid overlapping crunch periods.

Step-by-Step Filing Process via TRACES

The TRACES (TDS Reconciliation Analysis and Correction Enabling System) portal is the central platform for filing TDS returns online. TRACES 2.0, with its enhanced features, now offers 256-bit encryption for data security, a mobile-responsive interface, and automated validation checks that flag errors before submission. Here is the step-by-step process for filing your TDS return online.

Step 1: Collect all deduction details. Gather information for every payment on which TDS was deducted during the quarter, including the PAN of each deductee, the nature of the payment, the amount paid, the TDS rate applied, and the challan details for the deposited tax.

Step 2: Prepare the return file. Use the Return Preparation Utility (RPU) provided by NSDL (now Protean) or any compatible third-party software to enter the deduction data and generate the return file in the required format. Select the correct form number (Form 138, 140, 144, or 143 for FY 2026-27 onward).

Step 3: Validate using FVU. Before uploading, run the return file through the File Validation Utility (FVU). The FVU checks for structural errors, PAN mismatches, challan inconsistencies, and other data integrity issues. Only a file that passes FVU validation can be uploaded to the TRACES portal.

Step 4: Log in to TRACES and upload. Navigate to the TRACES portal, log in using your TAN credentials, and go to the "Upload TDS Return" section. Upload the validated FVU file along with the digital signature (DSC) or verification through the e-filing portal.

Step 5: Verify and download the acknowledgement. After successful upload, TRACES processes the return and generates a provisional receipt (Form 27A acknowledgement). Download and retain this receipt as proof of filing. The return status will update on the portal within a few days, and any discrepancies will be flagged for correction.

FVU Validation and Common Errors

The File Validation Utility is a critical checkpoint in the TDS return filing process. It ensures that the data in your return file conforms to the prescribed schema and catches errors that would otherwise lead to rejection. Some of the most common errors flagged by the FVU include invalid or inactive PAN entries, mismatches between challan amounts and the sum of deduction entries, incorrect assessment year or form type selection, missing or improperly formatted dates, and duplicate deductee records within the same return.

To minimize errors, always download the latest version of the FVU from the Protean (formerly NSDL) website before running validation. Cross-check your challan details against the OLTAS (Online Tax Accounting System) records, and verify all PANs through the income tax e-filing portal's PAN verification service. Entities making payments that involve transfer pricing considerations should pay special attention to the correct categorisation of payment types and applicable TDS rates for cross-border transactions.

Penalties for Late Filing

The consequences of late or non-filing of TDS returns are severe and are governed by two key provisions. Under Section 234E, a late filing fee of Rs 200 per day is levied for every day the return remains unfiled after the due date. This fee is capped at the total TDS amount payable for the quarter in question. The Section 234E penalty is mandatory and cannot be waived by the assessing officer.

In addition to the Section 234E fee, Section 271H empowers the assessing officer to impose a penalty ranging from Rs 10,000 to Rs 1,00,000 in cases where the TDS return is not filed within one year of the due date or where the return contains incorrect information. This penalty is discretionary and is separate from the daily late fee. Together, these provisions mean that prolonged delays can result in substantial financial liability. Understanding these key provisions affecting taxpayers is essential for every deductor.

Key Takeaways

The transition to the new TDS return forms (Form 138, 140, 144, and 143) is effective from April 1, 2026. The old forms (24Q, 26Q, 27Q, and 27EQ) remain applicable for periods before that date. Quarterly filing deadlines follow a consistent pattern: July 31 for Q1, October 31 for Q2, January 31 for Q3, and May 31 for Q4. The TRACES 2.0 portal is the designated platform for online filing, offering enhanced security and automated validation. Always validate your return file through the FVU before uploading to avoid rejection. Late filing attracts a mandatory fee of Rs 200 per day under Section 234E, capped at the TDS amount for the quarter. Section 271H carries an additional penalty of Rs 10,000 to Rs 1,00,000 for returns filed over a year late or with incorrect details.

Staying on top of TDS return filing is one of the most important recurring compliance tasks for any business in India. With the new forms and the enhanced TRACES platform, the process has become more structured, but the consequences of delays remain steep. Businesses, particularly those navigating the broader changes under the Income Tax Rules 2026 framework, should integrate their TDS compliance calendar with other regulatory deadlines to ensure nothing falls through the cracks. When in doubt, consult a qualified tax professional to review your filings before submission.
