Key Takeaways
TDS Due Dates — When Does "Late" Actually Begin?
Before you can calculate what you owe, you need to know when the clock started.
For TDS deducted between April and February, the deposit deadline is the 7th of the following month. So if you deduct TDS from a contractor payment in July, the deposit must hit the government account by 7 August. Miss it by a single day and you are late.
March is the exception. TDS deducted in March has until 30 April of the same financial year. This extended window exists because March is also ITR month and the government builds in a buffer, but it is a deadline, not a suggestion.
For TDS on property purchases under Section 194IA (where the buyer deducts from the seller), the deposit is due within 30 days from the end of the month in which the deduction was made, filed via Form 26QB. The same 30-day rule applies to TDS on rent above ₹50,000 per month (Form 26QC) and certain other special payments.
Government deductors deposit TDS on the same day as payment through a book entry. No challan needed. Non-government deductors use Challan 281, covered in detail below.
TDS return deadlines are a separate, additional obligation. Filing a quarterly return late adds Section 234E fees on top of the Section 201(1A) interest on any late deposit:
QuarterPeriodReturn Due DateQ1April – June31 JulyQ2July – September31 OctoberQ3October – December31 JanuaryQ4January – March31 May
These dates apply to Form 24Q (salary), 26Q (non-salary residents), 27Q (non-residents), and 27EQ (TCS).
One practical note: the TRACES system records the challan deposit date, not the acknowledgement date from NSDL. Pay before midnight on the due date. A challan deposited at 11:58 PM on the 7th is on time; one deposited at 12:01 AM on the 8th is late and triggers a part-month interest charge.
Interest On Late TDS Payment — Section 201(1A) Explained
This is the most misunderstood part of the whole equation, and getting it wrong is expensive.
Section 201(1A) of the Income Tax Act, 1961 governs interest on TDS defaults. There are two distinct rates depending on the nature of the failure:
The critical rule that trips up most founders: any part of a month counts as a full month. If you deposit TDS one day into a new month, you pay interest for that entire month. A single day's delay at a month boundary can cost you a full month's interest charge. Reference
Another costly misconception: interest does not run from the due date, it runs from the deduction date. If you deducted TDS on 10 August and the deposit was due 7 September but you paid on 10 September, the interest clock started on 10 August, not 7 September. That is already two months of interest, August and September, both part months, both charged as full months.
A quick example: TDS of ₹50,000 deducted on 10 July, deposited on 25 September, due date was 7 August. Months counted: August, part, September, part, equals 2 months. Interest equals ₹50,000 × 1.5% × 2 equals ₹1,500.
One more thing worth knowing: this interest is not deductible as a business expense. Unlike some other finance charges, Section 201(1A) interest comes entirely from post-tax cash. That makes the effective cost higher than the headline rate suggests.
The Income Tax Department also provides an online calculator for interest on delayed TDS deposit, use it to cross-check your manual calculation before paying.
Late Filing Fee Under Section 234E — The ₹200-Per-Day Charge
The TDS late fee section most businesses encounter is Section 234E. It is technically not a penalty in the income tax sense, it is a mandatory fee that the TRACES portal enforces automatically. You cannot file your TDS return without clearing it.
The rate is ₹200 per day for every calendar day the TDS return is filed after its quarterly due date. It is completely separate from, and stacks on top of, the Section 201(1A) interest on late deposit. Reference
The one saving grace: the total Section 234E fee cannot exceed the total TDS amount for that return. If TDS for the quarter was ₹15,000 and the late fee calculation comes to ₹18,000, you pay ₹15,000, not more.
The TDS delay penalty rate under Section 234E: ₹200 per day until the cap is hit.
Example: TDS return for Q1, due 31 July 2026, filed on 20 September 2026. That is 51 days late. TDS for the quarter equals ₹30,000. Late fee equals 51 × ₹200 equals ₹10,200. Since ₹10,200 is below the ₹30,000 cap, the full ₹10,200 is payable.
Beyond Section 234E sits Section 271H, which carries an additional discretionary penalty of ₹10,000 to ₹1,00,000 imposed by the Assessing Officer for late or incorrect TDS returns. However, Section 271H is not levied if you: (a) deposit the TDS with the government, (b) pay the Section 234E fee and Section 201(1A) interest, and (c) file the return within 1 year of the original due date. This is the one real exit ramp in the entire TDS late payment framework.
The difference in plain terms: Section 234E is automatic and unavoidable; Section 271H is at the AO's discretion and avoidable through prompt self-correction.
Also important: the demand for late filing fees under Section 234E cannot be waived by CPC-TDS. Once it is raised, it must be paid. There is no appeals mechanism for reducing it.
Bigger Business Consequence — Expense Disallowance Under Section 40(a)(ia)
Interest and late fees are irritating. This one can genuinely hurt your P&L.
Under Section 40(a)(ia) of the Income Tax Act, if TDS was not deducted on a payment, or was deducted but not deposited by the due date of filing the income tax return, generally 31 October for tax-audited entities, 30% of the underlying expense is disallowed and added back to your taxable income.
Here is what that looks like in practice. Say your Delhi consulting firm paid ₹10,00,000 in professional fees during FY 2025-26, Section 194J TDS applicable at 10 percent, without deducting TDS. At tax time:
These consequences of late TDS payment compound quickly. A missed TDS deduction on a modest contractor bill can turn into a five-figure compliance bill by the time the AO processes the return.
There is partial relief available. If the payee, the vendor you paid, has independently declared that income in their own ITR and paid tax on it, the Section 40(a)(ia) disallowance does not apply, as per the proviso to the section. But the burden of proof sits entirely with you, the deductor. You need the payee's ITR acknowledgement or Form 26AS extract to demonstrate this.
At the serious end, Section 276B of the Income Tax Act allows prosecution for wilful non-deposit of TDS that was already deducted. The exposure is rigorous imprisonment of 3 months to 7 years plus a fine. Prosecutions in practice are initiated for persistent defaults or large amounts, typically above ₹25 lakh, but the provision is not dormant, the Income Tax Department has been escalating enforcement in recent years. For a Bengaluru SaaS founder processing ₹30–40 lakh per quarter in contractor payments, this is not a theoretical risk.
How To Calculate Your Total Liability — A Step-By-Step Example
Let us put the whole picture together with one complete worked example.
Scenario: A Mumbai D2C brand deducted TDS of ₹80,000 from a vendor payment on 5 August 2025. Deposit due date: 7 September 2025. Actual deposit: 10 November 2025. TDS return for Q2, July to September, was due 31 October 2025, filed on 15 November 2025.
Step 1 — Section 201(1A) Interest, TDS deducted but deposited late
Count months from the deduction date, 5 August, to the deposit date, 10 November:
Interest equals ₹80,000 × 1.5% × 4 equals ₹4,800
Step 2 — Section 234E Late Filing Fee
Return due 31 October, filed 15 November equals 15 days late
Fee equals 15 × ₹200 equals ₹3,000
Cap check: ₹3,000 less than ₹80,000 TDS amount, no cap applies.
ComponentSectionRateAmountLate deposit interest201(1A)1.5% × 4 months₹4,800Late filing fee234E₹200 × 15 days₹3,000Total extra cost——₹7,800
The part-month rule is the biggest surprise for first-time payers. Notice that even though the payment was made on 10 November, just 10 days into the month, the entire month of November is counted. If this founder had paid on 31 October instead, November would not appear in the count and interest would drop to 3 months, saving ₹1,200.
Always verify your computation against the Income Tax Department's online calculator before paying.
How To Actually Pay The Interest And Late Fee — Challan 281 Step By Step
Both the Section 201(1A) interest and the Section 234E fee are paid through Challan 281 on the TIN-NSDL portal. Here is the exact sequence:
The most common mistake: depositing everything under the "TDS" head because it seems simpler. TRACES then cannot match the interest and fee correctly against the return, creating a mismatch demand later. Keep the three heads separate.
After payment, log in to TRACES, map the challan correctly in your TDS return, Form 24Q, 26Q, 27Q, or 27EQ as applicable, and file. The CIN from the challan is your proof of payment.
Founders who run multiple TDS categories simultaneously, salary, contractor payments, rent, professional fees, often have the computation done before the due date so the part-month trap never triggers. Finance teams using a service like Virtual Accounting typically have deposits and returns scheduled as a recurring item, not a reactive one.
Can The Penalty Be Waived? What The Law Actually Says
Section 201(1A) interest is a statutory charge. The CBDT has no discretionary power to waive it. Your CA cannot write a letter requesting a reduction. It accrues and it must be paid.
Section 234E fee is equally rigid. The TRACES portal physically blocks return submission without clearance of the outstanding fee. CPC-TDS has confirmed there is no mechanism to waive the demand once raised.
Section 271H, the ₹10,000 to ₹1,00,000 AO penalty, is the one component where an exit exists. As covered above, if you pay TDS, interest, and the Section 234E fee, and file the return within 1 year of the due date, the AO has no basis to levy Section 271H. Self-correction is your waiver.
CBDT Circulars: The CBDT has issued time-bound extensions in exceptional circumstances, most notably during COVID, Circular 9/2021 extended several return deadlines. Under normal operating conditions in 2026, no general relaxations are in place. Do not plan around the possibility of a future circular.
Section 273B provides a "reasonable cause" defence against Section 271H. However, the bar is genuinely high: documented system outages, natural disasters, or events entirely outside your control. Cash flow constraints, key person absence, and "the accountant was sick" do not qualify as reasonable cause. Courts have consistently held this position.
The practical takeaway: pay and file the moment you discover the lapse. Every additional day adds more 234E fee and one more potential part-month to the 201(1A) interest calculation. Self-correction before an AO notice always results in lower total liability than responding to a demand.
How To Correct The Situation And Stay Compliant Going Forward
Discovered a late TDS situation today? Here is the exact sequence to close it out.
Immediate Steps
If You Missed The Deduction Entirely
If you discover during your current FY 2026-27 ITR preparation that TDS was not deducted on a vendor payment in FY 2025-26, deduct and deposit immediately with Section 201(1A) interest. Also assess whether Section 40(a)(ia) disallowance applies to that year's tax return and adjust accordingly.
Going-Forward Compliance Calendar
Reconcile TDS deducted versus deposited monthly, not quarterly. Running a quarterly reconciliation means you find problems too late to fix cheaply.
After each quarterly return, pull the TRACES Justification Report. This is the Income Tax Department's own mismatch report, generated after processing your statement. Catching discrepancies on the Justification Report before an AO does is the difference between a self-corrected challan and a formal demand notice.
Finance teams managing multiple TDS categories, salary under 192, contractors under 194C, rent under 194I, professionals under 194J, often find that outsourcing TDS return filing removes the deadline-management burden entirely. Virtual Accounting handles end-to-end TDS compliance from ₹4,000 per month, covering computation, Challan 281 deposit coordination, return filing, and TRACES reconciliation so no quarter slips through.

FAQ
Does The Section 201(1A) Interest Run From The Due Date Or The Actual Deduction Date?
From the actual deduction date. Section 201(1A) is explicit: for TDS deducted but not deposited, interest runs from the date of deduction to the date of deposit. Not from the 7th-of-the-month due date. This is the most expensive misconception in TDS compliance, it means you owe more months of interest than most first-time payers expect.
What If I Deducted The TDS But Entered The Wrong Section Code On The Challan?
Challan correction is possible through the TRACES portal within a limited window. For corrections at the bank level, amount, minor head, banks allow corrections within 7 days of payment. For corrections to TAN, Assessment Year, or Nature of Payment after that window, you need to file an application with your jurisdictional Assessing Officer. Act quickly, the correction window is short and once it closes, the mismatch compounds. If you prefer not to handle corrections and TRACES mapping yourself, Virtual Accounting by AI Accountant can manage the end-to-end fix.
My Vendor Says TDS Credit Is Not Showing In Their Form 26AS. What Do I Do?
This usually means the TDS return was either not filed or the challan was mapped incorrectly. File or correct the return on TRACES, ensure the correct PAN of the deductee is entered, and wait 3 to 5 working days for Form 26AS to update. If the issue persists, raise a ticket on TRACES. You are liable for the deductee's credit not reflecting, it can block their ITR refund. To avoid repeated follow-ups, a managed service like Virtual Accounting by AI Accountant can take over TRACES reconciliation and deductee credit checks.
Is Section 234E A Penalty Or A Fee? Does It Matter?
Legally, it is a fee under the Income Tax Act, not a penalty. The distinction matters in one way: fees under Section 234E are not subject to waiver or appellate reduction in the way that penalties are. A penalty can sometimes be contested on grounds of reasonable cause; the Section 234E fee cannot. The demand stands regardless of the reason for the delay.
What If The TDS Amount Was Small, Say ₹500, But I Filed The Return 200 Days Late?
The Section 234E fee would theoretically be 200 × ₹200 equals ₹40,000, but it is capped at the total TDS amount. So the fee is capped at ₹500, the exact TDS amount for that return. The cap protects against disproportionate fees on small TDS amounts with long delays.
Can I Deduct The Section 201(1A) Interest Or Section 234E Fee As A Business Expense In My ITR?
No. Section 201(1A) interest is explicitly not deductible as a business expense. The same principle applies to Section 234E fees. Both come from post-tax funds. Factor this into your effective cost calculation when assessing the real damage from a late payment.
What Is The Difference Between TDS Interest Under Section 201(1A) And GST Late Payment Interest?
They are structurally different. GST late payment interest runs at 18% per annum on a daily basis, roughly 0.049% per day. TDS interest under Section 201(1A) runs at 1.5% per month, 18% per annum in theory, but charged on whole months, not daily. The part-month rule in TDS makes it operationally more punishing for short delays that cross a month boundary.
The Payee Told Me They Have Already Paid Tax On The Income I Paid Them. Does That Remove My TDS Liability?
It can remove the Section 40(a)(ia) expense disallowance, but only if you obtain documented proof, typically the payee's ITR acknowledgement showing the income declared and tax paid. It does not remove your Section 201(1A) interest or Section 234E fee obligation. The interest and fee apply to you as the deductor regardless of what the payee has done.
If TDS Is Deducted In Q4, January To March, But The Return Is Filed After 31 May, What Is The Last Date To Avoid Section 271H?
You have until 31 May 2027, one year from the Q4 FY 2025-26 due date, to file the return and clear interest and fees, and Section 271H will not be levied. Beyond that window, the AO has discretion to impose the ₹10,000 to ₹1,00,000 penalty. The 1-year window is a real and useful exit ramp, but it is not an invitation to delay.
Do Government Departments Also Pay Section 201(1A) Interest And Section 234E Fees?
Government deductors operate under a different deposit mechanism, same-day book entry, but they are not entirely exempt from consequences for late TDS returns. In practice, enforcement against government departments is less common, but the legal obligation exists. For private sector deductors, both charges apply in full with no exceptions.
