TDS Defaults 2026: Fix Interest, Penalties & TRACES Corrections

Every quarter, the Income Tax Department's CPC (Centralised Processing Centre) processes millions of TDS returns and automatically identifies mismatches — amounts deducted but not paid, PAN errors, short deductions, and late deposits. When it finds one against your business, you receive an intimation under what was previously Section 200A of the Income Tax Act, 1961 and is now the equivalent provision under the Income Tax Act, 2025.

You have two choices at that point: respond with a correction, or receive a demand notice with interest and penalties already compounded. The math is unforgiving. Interest on a TDS default runs at 1% to 1.5% per month from the very date the deduction was supposed to happen — not from the date you get caught. A ₹5 lakh TDS obligation missed for six months generates ₹4,500 to ₹6,750 in interest before the penalty conversation even starts. This guide walks you through every type of TDS default, exactly how the interest meter runs, what penalties apply, and the TRACES correction process to resolve each one.

What Counts as a TDS Default?

Non-Deduction and Short Deduction

The most common default is failing to deduct TDS at all — typically because the accounts team was unaware a payment had crossed the applicable threshold. Under the Income Tax Act, 2025, TDS obligations are triggered when cumulative payments to a single payee exceed the relevant threshold in a financial year. For professional or technical services (the equivalent of the old Section 194J), the threshold remains ₹30,000 per year. For rent (old Section 194I), it stays at ₹2,40,000 per year. For goods purchases (old Section 194Q, applicable to buyers with turnover exceeding ₹10 crore), it is ₹50 lakh per seller per year.

Short deduction is arguably more dangerous because it looks like compliance but isn't. This happens when you deduct TDS at a lower rate than required — for instance, applying 2% on a payment to a resident professional instead of the required 10%, or not accounting for surcharge and cess on non-resident payments. The CPC compares declared TDS against its own computation and flags every gap automatically.

Late Deposit After Deduction

Deducting TDS and then not depositing it on time is treated as a separate — and more serious — default. Once you have made the deduction, you are holding the government's money. The deposit due date is the 7th of the following month for payments made during the month, extended to 30th April for March deductions. If your TDS challan hits the bank on the 9th instead of the 7th — even for a single day — the interest clock starts running.

PAN and Return Errors

Quoting an incorrect PAN, filing a return with transposed figures, or mapping a payment to the wrong TDS section code are administrative defaults. They don't attract interest automatically, but they trigger mismatches in the deductee's Annual Information Statement. When your vendor's AIS does not reflect the credit they were expecting, they raise a grievance — which routes straight back to you through the Income Tax Department.

The Interest Clock: How Liability Compounds

1% Per Month: Non-Deduction

When you fail to deduct TDS at all, interest accrues at 1% per month — or part of a month — from the date deduction was required until the date of actual deduction. The calculation treats any part of a month as a full month, so even a one-day slip into a new calendar month adds an entire month's interest charge.

1.5% Per Month: Late Deposit

Once you have deducted TDS but delay the deposit, the rate jumps to 1.5% per month. The higher rate reflects a harder fact: you have already collected the tax from the payee, and the government's money is sitting in your current account earning nothing for the exchequer.

Worked Example: A ₹12 Lakh Consulting Contract

Your firm engages a management consultant at ₹3 lakh per quarter for four quarters. TDS at 10% equals ₹30,000 per quarter. You deduct correctly each time, but the Q1 (April–June) TDS of ₹30,000 is deposited on 15th August instead of 7th July.

• Delay: 7th July to 15th August = 40 days = 2 part-months
• Interest: ₹30,000 × 1.5% × 2 = ₹900

That seems manageable in isolation, but multiply across 50 vendors in a mid-size company and you are looking at ₹45,000 in avoidable interest in a single quarter. Now consider a more serious scenario: missing a ₹2 lakh TDS deduction entirely on a ₹20 lakh contract for six months.

• Non-deduction interest: ₹2,00,000 × 1% × 6 = ₹12,000
• Plus penalty exposure as described in the next section

Penalties and Prosecution Risk

The 100% Penalty

The penalty for failing to deduct TDS — previously codified in Section 271C of the Income Tax Act, 1961 — is carried forward under the Income Tax Act, 2025 with the same construct: the penalty equals the TDS amount not deducted or not paid. On a ₹2 lakh TDS default, the penalty exposure is ₹2 lakh on top of principal and interest. The Assessing Officer retains discretion to waive or reduce this penalty where the default was genuine and has since been remedied, but that discretion is not guaranteed and should not be treated as a fallback plan.

Late Filing Fees: ₹200 Per Day

A delay in filing the quarterly TDS return attracts a mandatory fee of ₹200 per day of delay, subject to a ceiling equal to the total TDS payable for the quarter. Under the Income Tax Act, 2025, this levy continues. It cannot be waived through an application or a condonation request.

If your Q4 TDS return — due 31st May — is filed on 15th July, that is 45 days late:

₹200 × 45 = ₹9,000 in compulsory late fees

This is before any interest or penalty computation.

What Changed Under the Income Tax Act, 2025

One targeted relief introduced by ITA 2025: TDS defaults on in-kind payments where the tax amount does not exceed ₹10 lakh have been decriminalized. Under the old Section 276B of the Income Tax Act, 1961, non-payment of TDS carried a prison term of three months to seven years. That criminal prosecution risk is now removed for this specific category of defaults. Civil interest and penalty remain fully applicable — only the prosecution threat has been lifted, giving smaller businesses meaningful breathing room when correcting genuine errors.

How to Detect a Default Before the Department Does

The AIS-TRACES Cross-Check

Log into the income tax portal and pull the Annual Information Statement for your entity. Cross-reference every TDS credit entry against your own accounting records. Any discrepancy — particularly where TDS credited in a deductee's AIS differs from what you declared in your return — signals a potential default. This cross-check takes under 30 minutes and should be a monthly procedure, not a quarterly scramble after the return deadline.

Separately, log into TRACES (traces.gov.in) and navigate to Statements/Payments → Defaults. The platform shows a computed interest summary for every quarter where a shortfall has been detected. By the time a paper intimation reaches your office, another month of interest has typically already accrued.

CPC Intimations vs Full Demand

The CPC's initial intimation — issued when it processes your quarterly TDS return — is a preliminary computation, not a final demand. You have 30 days from the intimation date to respond with corrections or payment. If you do not respond within that window, the intimation converts into a confirmed demand. A standing demand then attracts further interest at 1% per month until it is cleared in full, layering yet another interest stream on top of the original default.

The TRACES Correction Process: Step by Step

TRACES is the Income Tax Department's platform for correcting errors in filed TDS returns. Here is the exact workflow:

Step 1 — Generate a correction request. Log into TRACES → Statements/Payments → Request for Correction. Select the financial year, quarter, and form type: Form 26Q for non-salary TDS; Form 24Q for salary TDS.

Step 2 — Select the correction category. TRACES uses the following standard correction codes:

• C1: Update deductor details — address, PAN, name
• C2: Add or modify challan information
• C3: Add or modify deductee rows linked to an existing challan
• C4: Add a new deductee row using PAN
• C5: Update the PAN of an existing deductee
• C9: Add a fresh challan together with corresponding deductee rows

Step 3 — Pay the deficit and interest before submitting. On the income tax portal, create a new ITNS 281 challan covering the additional TDS amount plus the computed interest. Record the Challan Identification Number (CIN) — it must be attached to the correction request when submitted.

Step 4 — Submit the corrected return. Upload the corrected file using the Return Preparation Utility (RPU) available on TRACES, or complete the correction directly through the online correction interface. Authenticate via DSC or EVC before submission.

Step 5 — Regenerate Form 16 or Form 16A. Once the correction is processed — typically within three to seven working days — regenerate Form 16A from TRACES for each affected deductee and issue updated certificates without delay. Your vendor needs the corrected certificate to claim accurate TDS credit in their own return.

Common Mistakes That Compound TDS Defaults

Waiting for a formal demand notice. Every day after you identify a default, interest compounds. File the correction proactively the moment an AIS-TRACES cross-check reveals a gap. Proactive correction often avoids the penalty stage entirely.

Depositing only the TDS principal. Paying the shortfall without including computed interest leaves an open interest demand in your tax account. Always include interest in the same ITNS 281 challan and select the correct minor head: "Interest on TDS."

Using the wrong section code on the correction challan. Depositing TDS under the contractor-payment code when the professional-services code applies — or their ITA 2025 equivalents — creates a fresh mismatch and reopens the default. Verify codes against TRACES's downloadable section mapping list before generating any challan.

Skipping Form 16A regeneration. The original Form 16A issued before a correction is invalid once the correction is filed. Failing to issue an updated certificate triggers deductee grievances and can restart the entire default cycle for the same payment.

Undocumented nil-TDS deductions. If you deducted nil TDS because a vendor held a valid lower-deduction certificate — the equivalent of old Form 13, now processed under ITA 2025's revised application framework — map that certificate reference in your TRACES filing. Without the mapping, the CPC treats the nil deduction as non-deduction and raises an interest demand automatically.

Key Takeaways

• Interest at 1% per month accrues from the date TDS was due to be deducted until actual deduction; 1.5% per month applies from deduction date to deposit date — both treat any part of a month as a full month.
• The penalty can equal 100% of the TDS amount not deducted or paid — on a ₹5 lakh shortfall, that is a ₹5 lakh additional liability, entirely separate from interest.
• The Income Tax Act, 2025 decriminalized TDS defaults on in-kind payments below ₹10 lakh, removing prosecution risk for smaller errors while keeping civil penalties fully intact.
• TRACES corrections (C1–C9) are the standard remediation path — pay TDS principal plus computed interest in the correction challan before submitting the revised return.
• Monthly AIS-TRACES reconciliation is the most cost-effective TDS control you can implement — it surfaces defaults within days rather than letting interest compound for months.

How corpus Helps

corpus computes TDS liability at the moment of payment entry. It flags every transaction that crosses an applicable threshold, applies the correct rate from the updated ITA 2025 rate schedule, and generates the ITNS 281 challan pre-filled with both the TDS amount and computed interest when you are making a delayed deposit. The TDS reconciliation module matches your declared deductions against the TRACES consolidated statement, surfacing discrepancies before the CPC does. When a correction is needed, corpus exports a TRACES-ready file in RPU format so your team uploads directly — no manual data re-entry, no transposition errors.

TDS compliance in 2026 is a month-end discipline, not an end-of-quarter fire drill. The right platform makes those monthly checks a 20-minute routine rather than a full-day investigation.
