TDS Return Filing — Due Dates, Forms and Online Process FY 2025-26

TDS Return Filing — Due Dates, Forms and Online Process FY 2025-26

Every deductor — company, LLP, firm or audited individual — must file a quarterly TDS return reporting every rupee of tax withheld, the challan used to deposit it, and the PAN of each deductee. For FY 2025-26 (Assessment Year 2026-27), four forms cover the full spectrum: Form 24Q for salary, Form 26Q for resident non-salary payments, Form 27Q for non-resident payments, and Form 27EQ for TCS. Miss the due date and Section 234E of the Income-tax Act 1961 charges Rs. 200 a day; ignore the return entirely and Section 271H can add up to Rs. 1 lakh on top. Here is every form, every deadline, the exact online filing sequence, and a clear picture of what non-compliance costs.

Who Must File a TDS Return?

Any person who holds a Tax Deduction Account Number (TAN) and deducts tax at source is required to file a quarterly TDS return. This includes:

• All companies (domestic and foreign companies with an Indian PE)
• Partnership firms and LLPs subject to audit under Section 44AB of the Income-tax Act
• Individuals and HUFs subject to audit under Section 44AB
• Central and State government drawing and disbursing officers (DDOs)
• Trusts, societies and AOP/BOI entities making any TDS-deductible payment

You do not need to file a nil TDS return if you made no deductible payments in a quarter, but many deductors do so voluntarily to avoid compliance-gap notices. If you hold a TAN and have any deductible payment in a quarter, filing is mandatory. No grace on that point.

The Four TDS and TCS Return Forms

Choosing the correct form is not optional. The TRACES system does not auto-redirect misclassified returns — a non-resident payment reported in Form 26Q instead of Form 27Q requires a correction statement to fix, causing unnecessary delay and default exposure.

Form 24Q — TDS on Salary (Section 192)

Form 24Q reports TDS deducted on salary payments. The structure differs between quarters:

• Q1 to Q3: Only Annexure I — challan summary and deductee detail. No salary breakup is required.
• Q4: Annexure I and Annexure II — full salary details per employee including gross salary, allowance exemptions (HRA, LTA), Chapter VI-A deductions (80C, 80D, 80CCD), the rebate under Section 87A, net taxable salary, and the total TDS for the year.

Annexure II in Q4 is the source for Form 16 Part A, which TRACES generates. Any error here — wrong chapter VI-A figure, wrong PAN, transposed digits in the TDS amount — propagates into the employee's Form 16 and eventually into their ITR, triggering AIS mismatches. Get Q4 Annexure II right the first time.

Form 26Q — TDS on Non-Salary Payments to Residents

Form 26Q is the workhorse for most businesses. It covers all TDS deducted on payments to residents other than salary. Key sections:

Each payment type requires a separate deductee row with the relevant section code. If one vendor receives both professional fees and rent, report them in two separate rows under Section 194J and Section 194I respectively. Lumping them into one row mis-states the rate and creates a short-deduction default.

Form 27Q — TDS on Payments to Non-Residents

Form 27Q covers TDS under Section 195 and allied sections (196A, 196B, 196C, 196D) on payments to non-residents, foreign companies, and NRIs. There is no threshold under Section 195 — the very first rupee of a taxable payment to a non-resident attracts TDS.

The applicable rate depends on:

1. The nature of payment (royalty, FTS, interest, dividend, capital gains, business income)
2. Whether a Double Taxation Avoidance Agreement (DTAA) applies and what rate it prescribes
3. Whether the non-resident has furnished a Tax Residency Certificate (TRC) and Form 10F to claim the DTAA benefit
4. Whether the non-resident has a Permanent Establishment (PE) in India

Cross-border payments are where TDS errors carry the highest monetary exposure, and they are increasingly common as Indian businesses engage foreign SaaS vendors, consulting firms, and group entities. Form 27Q must be filed even if you have deducted at nil rate under a DTAA — the filing obligation is separate from the deduction obligation.

Form 27EQ — Tax Collected at Source (TCS)

Form 27EQ reports tax collected at source under Section 206C. File this form if you are:

• A seller of scrap, minerals, forest produce, or alcoholic liquor for human consumption
• A seller of motor vehicles above Rs. 10 lakh to any buyer
• An authorised dealer collecting TCS on overseas remittances under the Liberalised Remittance Scheme (LRS) under Section 206C(1G)
• A seller of foreign tour packages (Section 206C(1G))

The due dates for Form 27EQ are identical to those for TDS returns.

Quarterly Due Dates for FY 2025-26

These due dates apply to non-government deductors. Government DDOs (who remit TDS on the day of deduction without a challan) have a separate, earlier set of deadlines under CBDT's annual circular.

The Q4 due date — 31 May 2026 — falls in FY 2026-27 and is the one most frequently missed. The March year-end rush consumes attention, and by the time May arrives the urgency has faded. Set a calendar reminder today. If you are planning for FY 2026-27 returns, the same quarterly cycle repeats: Q1 (April–June 2026) return is due 31 July 2026.

TDS Challan Payment: You Must Pay Before You Can File

The TDS return is a reconciliation of tax already deposited. If the challan is not in the system, the return cannot be filed clean. Deposit TDS using Challan ITNS 281 via the income-tax portal or an authorised bank by these deadlines:

• 7th of the following month for TDS deducted from April through February
• 30th April for TDS deducted in March (the extended deadline)

For TDS on property purchase under Section 194-IA, the deposit deadline is the 30th of the month following the month of deduction — a different rule from the general 7th-of-the-month requirement.

After payment, the challan appears in OLTAS (Online Tax Accounting System) within 24–48 hours. Do not attempt to file your TDS return the same day you pay the challan — OLTAS lag causes challan mismatch defaults that must be corrected later.

How to File a TDS Return Online: Exact Step-by-Step

The official path uses the free Return Preparation Utility (RPU) and File Validation Utility (FVU) from Protean eGov Technologies (formerly NSDL), available at https://www.tin-nsdl.com. Always download the current version of each utility before starting — using a version even one release out of date can produce FVU errors for new sections introduced mid-year.

Step 1 — Download the current RPU Navigate to TIN-NSDL → TDS → Return Preparation Utilities. Download RPU (current version) for the relevant form (24Q/26Q/27Q/27EQ). Install and open.

Step 2 — Enter challan details (Annexure I, Part I) For each challan paid during the quarter, enter: BSR code of the bank branch, date of deposit, challan serial number, TDS deposited against each section, and the total deposited amount. These must match OLTAS exactly — character for character on the BSR code.

Step 3 — Enter deductee details (Annexure I, Part II) For each deductee in each challan: PAN, full name as per PAN, amount credited or paid, TDS deducted, TDS rate applied, and the section code. Before typing any PAN, verify it at incometax.gov.in → Verify Your PAN or through the bulk verification on TRACES. An invalid PAN is more expensive to fix after filing than before.

Step 4 — Run the FVU and generate the .fvu file Save the RPU data as a .txt file and run it through the FVU. The FVU validates structure, mandatory fields, PAN format, and challan reconciliation. A clean run produces a .fvu file and a Form 27A summary sheet — print and sign the Form 27A before uploading.

Step 5 — Upload on the income-tax portal Log in at https://www.incometax.gov.in with your TAN and password. Go to e-File → Income-tax Forms → File Income-tax Forms and select the correct form number. Upload the .fvu file. Companies must authenticate with a DSC (Digital Signature Certificate). Non-corporate deductors may use an EVC (Electronic Verification Code) via net banking.

Step 6 — Save the PRN (Provisional Receipt Number) On successful acceptance, the portal issues a PRN. This is your proof of filing. If the return is rejected — which happens for duplicate filing attempts or certain structural errors — the portal displays a rejection message. Diagnose, correct, and re-upload.

Step 7 — Issue Form 16 / 16A from TRACES Once the return is processed (typically a few working days), log into TRACES at https://www.tdscpc.gov.in. Download digitally signed Form 16 Part A (salary) or Form 16A (non-salary). Issue these to deductees by the due dates: Form 16A within 15 days of the return due date for each quarter; Form 16 (salary) by 15 June following the end of the financial year.

Section 234E, 271H and 40(a)(ia): Understanding the Full Penalty Stack

Section 234E — Mandatory Late-Filing Fee

The Section 234E fee is not an officer's discretionary levy — it is a mandatory fee that the system computes and the portal requires you to pay before it accepts a belated return. The rate is Rs. 200 per day from the day after the due date until the date of actual filing, capped at the total TDS amount in the return.

Section 271H — Penalty for Non-Filing or Incorrect Particulars

Where a return is not filed within one year of the due date, or is filed with materially incorrect information (wrong PAN, wrong challan data, wrong TDS amounts), the Assessing Officer can levy a penalty of Rs. 10,000 to Rs. 1,00,000. This is charged over and above the Section 234E fee — the two run concurrently, not in lieu of each other.

A protecting proviso exists: if the TDS was deposited on time, the return is filed before the one-year mark, and the Section 234E fee has been paid, the AO may elect not to levy the 271H penalty. "May" is not "must" — and the protection disappears entirely at the one-year mark.

Section 40(a)(ia) — Disallowance for Non-Deduction

If you fail to deduct TDS on an expense, or deduct but fail to deposit, 30% of the payment is disallowed as a business deduction when computing your taxable income. The disallowance applies in the year of payment and cannot be reversed until TDS is eventually deposited and the deductee includes the income in their return with a certificate that they have paid the tax themselves.

Section 201(1A) — Interest on Late Deduction and Late Deposit

Interest under Section 201(1A) runs at two rates:

• 1% per month (or part thereof) from the date TDS was deductible to the date of actual deduction
• 1.5% per month from the date of actual deduction to the date of deposit into government account

Worked Example: The Real Rupee Cost of Two Common Defaults

Scenario: XYZ Private Limited, FY 2025-26.

Default 1 — Late filing of Q1 Form 26Q: The company deducts Rs. 80,000 TDS on professional fees (Section 194J) during April–June 2025. The Q1 return due date is 31 July 2025. Due to a staff change, the return is filed on 1 October 2025 — 62 days late.

• Section 234E fee = Rs. 200 × 62 = Rs. 12,400
• Cap test: Rs. 12,400 < Rs. 80,000 (TDS amount) ✓ — full fee applies
• This Rs. 12,400 must be paid as a separate ITNS 281 challan before the portal accepts the belated return

Default 2 — Missed TDS on contractor payment: The same company pays Rs. 5,00,000 to a contractor during Q1 under Section 194C without deducting TDS (the team thought the Rs. 1 lakh aggregate threshold had not been crossed — it had).

• Section 40(a)(ia) disallowance = 30% × Rs. 5,00,000 = Rs. 1,50,000 added back to taxable income
• Additional corporate tax at 25.168% (including surcharge and cess) ≈ Rs. 37,752
• Section 201(1A) interest at 1%/month for ~3 months before deduction = 3% × Rs. 10,000 (the TDS itself at 1% of Rs. 10,00,000 — wait, 194C rate is 1% individual/2% company; assume 2% on Rs. 5,00,000 = Rs. 10,000 TDS): Rs. 300 interest — a small number, but it compounds quarterly across larger vendor bases.

Combined cost of two lapses in one quarter: Section 234E fee Rs. 12,400 + excess tax from disallowance Rs. 37,752 + 201(1A) interest = approximately Rs. 50,500 for a company that thought it had a clean compliance record. Scale this across a full year with multiple vendors and the numbers become material fast.

PAN Validation and Section 206AA: The Default Most Deductors Discover Too Late

Section 206AA requires TDS at the higher of 20% or twice the normally applicable rate when the deductee has not furnished a valid, operative PAN. Following CBDT's Aadhaar-PAN linkage drive, many PANs that passed format checks are now marked "inoperative" in the Income Tax Department's database. The inoperative status does not show up as an error when you type the PAN into the RPU — the RPU only validates the format, not the operational status. The mismatch surfaces after TRACES processes the return as a short-deduction default.

Pre-payment PAN validation process:

1. Log into TRACES → go to Bulk PAN Verification under the Statements / Payments menu. Upload a CSV of all active vendor and employee PANs.
2. Download the results. Any PAN marked "Inoperative" or "Invalid" requires immediate follow-up.
3. For inoperative PANs, either obtain a fresh PAN from the vendor (after they link Aadhaar) or apply 20% TDS until the status is resolved.
4. Run this check at the start of each month — not once a year. Vendors change, Aadhaar linkage status changes.

Deductors who automate this monthly bulk check eliminate the single largest source of post-filing TRACES defaults. Those who do it annually discover problems only when the short-deduction demand arrives — often covering six to eight quarters of accumulation.

Correction Returns and TRACES Default Management

After your return is processed, TRACES generates a Default Summary containing:

• Short deduction: TDS deducted is lower than the amount required at the applicable rate
• Late payment interest: Challan deposited after the statutory deadline
• PAN mismatch: PAN in the return does not match TRACES records
• Challan mismatch: BSR code, date, or challan serial number does not reconcile with OLTAS
• Interest on late deposit under Section 201(1A)

Each default can be resolved by filing a Correction Statement in the RPU. Select "C" (Correction) at the start, specify the type of correction required (challan correction, deductee record correction, or salary detail correction for Form 24Q), make the changes, re-validate through FVU, and upload on the portal.

Operational discipline that prevents defaults from becoming demands:

• Check TRACES on the 1st working day of each month.
• Download and review the Default Summary for the most recently processed quarter.
• Set an internal 30-day target to file correction statements for any open defaults.
• Defaults older than 60 days without action typically convert to Section 156 demand notices with interest locked in at 1.5% per month.

The correction process is not punitive if you act quickly. The problem is that many deductors check TRACES only at year-end or when a notice arrives — by which point several quarters of interest have accrued.

TDS on Cross-Border Payments: Form 27Q, 15CA and 15CB

If your business pays a foreign software vendor, non-resident consultant, overseas parent, or NRI professional, the compliance stack goes beyond Form 27Q:

Step 1 — Determine Indian taxability: Is the payment business income with no PE in India (often not taxable), royalty (taxable in India even without PE under Section 9(1)(vi)), fees for technical services or FTS (taxable under Section 9(1)(vii)), interest, or dividends?

Step 2 — Check the applicable DTAA: Verify the treaty rate for India with the payee's country. To apply the treaty rate, you must hold a valid TRC (Tax Residency Certificate) issued by the foreign tax authority and a completed Form 10F from the non-resident. Without these documents in hand, apply the Act rate — you cannot apply the DTAA rate on faith.

Step 3 — Comply with Rule 37BB (Forms 15CA/15CB): For taxable remittances above Rs. 5 lakh in the financial year to the same payee, file Form 15CA Part C on the income-tax portal and obtain Form 15CB (a CA certificate) before remitting through the bank. The bank is required to verify the Form 15CA before processing the outward remittance. Form 15CA and Form 15CB cannot be filed retrospectively after the remittance has already been made.

Step 4 — File Form 27Q for the relevant quarter, reporting the payment, rate applied, and TDS deducted.

The most expensive error in 27Q compliance is applying the Act rate (up to 40% on FTS for foreign companies) when a lower DTAA rate was available but not documented — or conversely, applying the DTAA rate without holding the TRC and Form 10F, creating a short-deduction demand at the higher Act rate.

Common Mistakes That Generate TRACES Defaults

These are the filing errors that drive the highest volume of short-deduction notices and correction workload in practice:

1. Using Form 26Q for a non-resident payment: The return processes but TRACES flags the section-rate mismatch. A full correction statement is required.
2. Filing before the challan appears in OLTAS: Always wait 48 hours after challan payment. Same-day filing creates challan mismatch defaults that are time-consuming to fix.
3. Skipping bulk PAN validation: A single large vendor base can have dozens of inoperative PANs generating simultaneous short-deduction defaults.
4. Submitting Q4 Form 24Q without completing Annexure II: TRACES processes the return, but Form 16 cannot be generated and employees are unable to file accurate ITRs.
5. Swapping the "Amount Paid" and "TDS Amount" fields: Entering Rs. 10,000 (TDS) in the "Amount Paid/Credited" column and Rs. 10,00,000 (the gross payment) in the "TDS Deducted" column is a data-entry error that creates an absurd default — and happens more frequently than any CA would like to admit.
6. Missing the Q4 return deadline (31 May 2026): The May date feels distant after the March year-end scramble. The Section 234E clock starts running on 1 June.
7. Paying the Section 234E fee but not uploading the return: Fee payment does not substitute for filing. The default remains open until the return is actually uploaded and accepted.
8. Issuing Form 16A late: Form 16A must be issued within 15 days of the return due date for each quarter. For Q4 FY 2025-26 (return due 31 May 2026), Form 16A is due by 15 June 2026.

Key Takeaways

• Four forms, no substitutes: 24Q for salary, 26Q for resident non-salary, 27Q for non-residents, 27EQ for TCS. Misclassification requires a correction return — there is no shortcut.
• Q4 FY 2025-26 return is due 31 May 2026 — the only quarter whose deadline falls in FY 2026-27. Miss it and Section 234E starts on 1 June 2026.
• Section 234E = Rs. 200 per day, capped at TDS amount: On a Rs. 80,000 TDS return, a 62-day delay costs Rs. 12,400 in mandatory pre-filing fees. This is not negotiable — the portal will not accept the return until the fee is deposited.
• Section 40(a)(ia) = 30% disallowance: On Rs. 5 lakh of contractor payments where TDS was missed, Rs. 1,50,000 is added back to taxable income. The consequential tax cost far exceeds the TDS that should have been deducted.
• Monthly PAN validation is non-negotiable: Inoperative PANs trigger Section 206AA (20% TDS). By the time TRACES surfaces the default, multiple quarters of interest may have accrued.
• *Cross-border payments require TRC + Form 10F before remittance*: DTAA benefits cannot be applied retroactively, and Form 15CA/15CB cannot be filed after the bank has already processed the remittance.
• TRACES defaults are not self-correcting: Check the Default Summary on the 1st of every month and file correction statements within 30 days. Defaults that age past 60 days typically convert to Section 156 demands with locked-in interest.
