Tax Deducted at Source (TDS) is one of the most pervasive tax compliance obligations for Indian businesses. Any entity — company, LLP, partnership, or audit-required individual — that makes payments above specified thresholds must deduct TDS at prescribed rates and deposit it with the government. Failing to file TDS returns on time triggers mandatory late fees of ₹200 per day under Section 234E, plus discretionary penalties of up to ₹1,00,000 under Section 271H.
Yet TDS return filing is an area where even experienced finance teams make costly errors — wrong forms, mismatched PAN details, incorrect sections or rates, and missed corrections that cascade into employee Form 16 disputes. This guide covers the complete TDS return filing process for FY 2025-26, from the right forms to use, quarterly due dates, the TRACES portal filing process, corrections, and the exact penalty structure.
TDS returns are filed quarterly: Q1 by 31 Jul, Q2 by 31 Oct, Q3 by 31 Jan, Q4 by 31 May. Salary TDS: Form 24Q. Non-salary resident payments: Form 26Q. NRI payments: Form 27Q. TCS: Form 27EQ. TDS deposited via Challan 281 by 7th of following month. Late fee: ₹200/day (Sec 234E). File on TRACES using NSDL RPU tool with your TAN.
Our tax specialists file Form 24Q, 26Q, and 27Q accurately on TRACES — and generate Form 16/16A for your employees and vendors.
Tax Deducted at Source (TDS) is a mechanism under the Income Tax Act, 1961 where the payer (deductor) deducts a specified percentage of tax before making certain payments — salaries, rent, professional fees, contractor payments, interest, commissions, and others. This deducted amount is deposited with the government on behalf of the payee (deductee), who then claims credit for it against their total income tax liability via Form 26AS.
TDS return filing is the quarterly compliance requirement where deductors submit a consolidated statement of all TDS transactions — listing every deductee's PAN, the payment amount, the applicable TDS section, the rate used, and the corresponding challan against which the TDS was deposited. The Income Tax Department uses this data to pre-populate deductees' Form 26AS and to cross-verify tax payments.
It is mandatory under Section 206 of the Income Tax Act, 1961. Failure to file constitutes a statutory default, regardless of whether the TDS itself was correctly deducted and deposited. The late filing fee under Section 234E runs from the due date to the actual date of filing and is a minimum fee — no extension or waiver is available.
📌 Who Issues TDS Compliance Notices? The TRACES system automatically flags deductors who have not filed quarterly returns. Notices under Section 200A (for computing fee and interest) and Section 271H (for penalty) are issued by the Centralised Processing Cell (CPC-TDS), not the local Assessing Officer, making them largely automated and difficult to contest.
Every person who deducts TDS is required to file quarterly TDS returns. This includes:
⚠️ TDS on Rent (Section 194-IB): Even individuals not required to get audited must deduct TDS at 5% if they pay rent exceeding ₹50,000 per month. However, this requires filing Form 26QC (not the regular quarterly return) and is a one-time annual compliance, not quarterly.
Filed quarterly by employers deducting TDS under Section 192. Q1–Q3 include salary details; Q4 includes the complete annual salary and tax computation for each employee.
Filed quarterly for all TDS deductions on payments to resident Indians other than salary — contractors (194C), professional fees (194J), rent (194I), interest (194A), commission (194H), etc.
Filed quarterly for TDS deducted on payments to non-residents and foreign companies — including DTAA (Double Tax Avoidance Agreement) benefits claimed. Requires foreign entity details.
Filed quarterly by sellers who collect TCS on sale of goods (coal, scrap, forest produce, motor vehicles, etc.) under Section 206C. Not TDS — it is collected from the buyer at the point of sale.
📌 Most Businesses File: Form 24Q (for employee salaries) and Form 26Q (for vendor/contractor/professional payments). Only those dealing with foreign entities need Form 27Q, and only sellers of specific goods need Form 27EQ.
| Quarter | Period | TDS Deposit By (7th of next month) | TDS Return Due Date |
|---|---|---|---|
| Q1 | April 1 – June 30, 2025 | 7th of each month (April TDS by 7 May) | 31 July 2025 |
| Q2 | July 1 – September 30, 2025 | 7th of each month | 31 October 2025 |
| Q3 | October 1 – December 31, 2025 | 7th of each month | 31 January 2026 |
| Q4 | January 1 – March 31, 2026 | 7th of each month; March TDS by 30 April 2026 | 31 May 2026 |
TDS deducted in March (including salary) has an extended deposit deadline of 30 April (instead of the usual 7th of the next month). This is to align with year-end salary processing. However, the Q4 TDS return is due on 31 May — not 30 April.
TAN (Tax Deduction and Collection Account Number) is a 10-character alphanumeric number (e.g., MUMF12345A) assigned by the Income Tax Department. Every entity required to deduct or collect TDS/TCS must obtain a TAN before making any TDS payment.
Without a TAN, you cannot: deposit TDS using Challan 281, file quarterly TDS returns on TRACES, or generate Form 16/16A certificates for deductees. Using an incorrect TAN or filing without a TAN results in the challan not being matched to your account, causing the deductee's Form 26AS to remain uncredited.
How to register for TAN: Apply using Form 49B online at tin.tin.nsdl.com or through a TIN-FC. Processing typically takes 3–7 working days. Government fee: ₹65 (excluding service charge). The TAN is valid permanently — no renewal required.
📌 Already have TAN? Register it on the TRACES portal (traces.gov.in) and the Income Tax e-filing portal (incometax.gov.in) before filing returns. TRACES registration is a one-time step required to access Form 16/16A downloads and corrections.
Collect all payment records for the quarter: deductee PAN, name, payment amount, applicable section, TDS rate, TDS amount deducted, and the challan number against which it was paid. For salary (Form 24Q), compile monthly salary computation statements.
Before filing the return, ensure all TDS for the quarter has been deposited via Challan 281 (ITNS 281) through internet banking or at the bank. Keep the BSR code, challan serial number, and payment date — these are mandatory fields in the TDS return.
Download the latest Return Preparation Utility (RPU) from tin.nsdl.com. It is a Java-based application. Also download the File Validation Utility (FVU) from the same page. RPU generates the .fvu file needed for upload.
Open RPU and select the form type (24Q/26Q/27Q/27EQ), quarter, and financial year. Fill in: (a) deductor details — TAN, name, address; (b) challan details — BSR code, date, amount, serial number; (c) deductee details — PAN, name, payment amount, section, TDS deducted. Validate data using FVU to check for errors before uploading.
Log in to TRACES (traces.gov.in) using your TAN credentials. Go to Statements / Payments → Upload TDS. Upload the .fvu file generated by RPU. Use Digital Signature Certificate (DSC) or Electronic Verification Code (EVC) for authentication. Alternatively, submit the .fvu file at a TIN-FC (authorised NSDL centre).
After successful upload, you receive a Provisional Receipt Number (PRN). This PRN is essential for future corrections (revision statements) and for tracking the processing status. Save it securely. Processing typically takes 2–7 working days, after which the return status shows "Processed" on TRACES.
Once the return is processed, go to TRACES → Downloads → Form 16 (for salary) or Form 16A (for non-salary). Download digitally signed certificates for each deductee. Issue Form 16A to vendors and Form 16 to employees within the due dates. Form 16 must be issued by 15 June; Form 16A by 15 days from the return due date.
Challan 281 (ITNS 281) is the designated challan for TDS and TCS payments. It must be paid before the return is filed — the return links each challan to the corresponding deductee payments. A mismatch between the challan amount and the TDS claimed in the return causes processing errors.
How to pay Challan 281 online: Visit tin.tin.nsdl.com → e-Payment of Taxes → ITNS 281. Enter TAN, assessment year, select Major Head (0021 for companies/0020 for others for income tax), Minor Head (200 for TDS payable), Nature of Payment (the relevant TDS section), and the tax amount. Pay via net banking (immediate credit) or NEFT/RTGS. Save the challan receipt with BSR code and serial number.
⚠️ Common Challan Error: Many deductors accidentally select the wrong assessment year or wrong Major/Minor head when paying Challan 281. A challan paid under wrong details requires a correction request to the bank within 7 days of payment — after that, you must apply to the jurisdictional Assessing Officer. Double-check all challan details before payment.
Form 16 and Form 16A are TDS certificates issued to deductees confirming the TDS deducted and deposited on their behalf. These certificates are essential for deductees to claim TDS credit in their income tax returns.
| Feature | Form 16 | Form 16A |
|---|---|---|
| For | Employees (salary TDS under Sec 192) | Non-salary deductees (contractor, rent, interest, professional) |
| Parts | Part A (TRACES-generated) + Part B (employer-prepared) | Single TRACES-generated certificate |
| Due date | 15 June of assessment year | 15 days from TDS return due date for each quarter |
| Frequency | Annual (covers full FY) | Quarterly (per quarter) |
| Source | Downloaded from TRACES after Q4 return processed | Downloaded from TRACES after each quarter's return processed |
✅ Digital Signature on Form 16/16A: Form 16/16A downloaded from TRACES comes with a digital signature from the Income Tax Department. This is legally valid. Do not accept manually typed Form 16 without the TRACES-generated Part A — it may be fraudulent.
TDS returns can be corrected by filing correction statements (revised TDS returns). Unlike GST returns or income tax returns, TDS returns can be corrected multiple times with no limit on the number of corrections. Common corrections include:
Correction statements are filed using the NSDL RPU tool (same as original filing), but in "Correction" mode. You need the original PRN (Provisional Receipt Number) from the original filing. After processing the correction, you receive a new PRN.
📌 Online Correction via TRACES: For simpler corrections (adding/updating PAN for a deductee not found in original return), TRACES allows an online correction facility without the RPU tool. Log in to TRACES → Statements/Payments → Request for Correction → Select the quarter and type of correction.
| Situation | Interest Rate | Computed From → To |
|---|---|---|
| TDS not deducted at all | 1% per month | Date on which TDS was required to be deducted → Date of actual deduction |
| TDS deducted but deposited late | 1.5% per month | Date of deduction → Date of actual deposit |
| TDS not deducted (treated as assessee in default) | 1% per month on shortfall | Calculated on the amount not deducted × months of default |
🛑 Disallowance of Expense: If TDS is not deducted on a payment, 30% of such expense is disallowed under Section 40(a)(ia) while computing business income for the financial year. This effectively increases your taxable income and income tax liability in addition to the TDS interest and penalty.
Technology services are often incorrectly classified. Software subscriptions (SaaS), cloud hosting, and standard IT products fall under Section 194C (1%/2% for contractor payments), not Section 194J (10% for professional services). If your vendor provides standardised software, apply 194C. If they provide customised software development or technical consulting, apply 194J. The CBDT has clarified this multiple times but confusion persists.
TDS on contractor payments under Section 194C applies when the aggregate payment to a single contractor in a financial year exceeds ₹1,00,000 (or single payment exceeds ₹30,000). These limits reset on 1 April every year. A contractor paid ₹40,000 in March 2025 and ₹70,000 in April 2025 does not trigger TDS in April — the new year count starts fresh.
If a deductee does not provide a valid PAN, Section 206AA mandates TDS at 20% (instead of the regular rate). Worse, if PAN is not mentioned in the TDS return, the deductee cannot claim credit in their Form 26AS, which creates disputes and reconciliation issues. Always collect PAN before making any payment subject to TDS.
TDS is required to be deducted at the time of credit or payment, whichever is earlier. If you book an expense in your books (credit to the vendor's account) before actually paying, TDS obligation arises at the time of booking, not payment. Many businesses miss this for year-end accruals.
Our tax team handles quarterly TDS returns, challan reconciliation, corrections, and Form 16 generation. Flat-rate pricing.
TDS return filing is a non-negotiable quarterly obligation for every Indian business that makes qualifying payments. The four-form structure (24Q, 26Q, 27Q, 27EQ), quarterly deadlines, Challan 281 deposit requirements, and the strict late fee structure under Section 234E leave no room for casual compliance. A one-day delay on a ₹10 lakh TDS return triggers ₹200 in fees — and the penalty accumulates every day until filing.
The TRACES portal has made the process relatively streamlined for businesses with clean data — provided the TAN is registered, Challan 281 is paid on time with correct details, and the NSDL RPU is used to generate validated .fvu files. The most critical protection is upstream: ensuring every vendor's PAN is collected before payment, the right section and rate is applied, and all year-end accruals are correctly accounted for before the Q4 filing in May.
