Tax Collected at Source: The Seven-Day Deadline for Sellers to Deposit TCS

The headline deadline on every seller's radar for 16 October 2026 is not a market open but a compliance clock. Tax collected at source (TCS) under section 206C of the Income Tax Act 1961 runs on a strict seven-day deposit rhythm, and the quarterly reporting window for the July-to-September 2026 quarter closed on 15 October 2026. From 16 October 2026, any collector who has filed the quarterly statement Form 27EQ late starts accruing a fee of Rs 200 for each day of delay under section 234E, so the day after a statutory deadline is exactly when the arithmetic of non-compliance begins to bite.

TCS is the mirror image of tax deducted at source. Where TDS is withheld by the payer, TCS is added on top of the sale price and collected by the seller from the buyer on specified transactions such as the sale of scrap, the sale of a motor vehicle above Rs 10 lakh, and foreign remittances under the Liberalised Remittance Scheme. The collector is only a conduit: the money belongs to the exchequer, which is why the law gives sellers just seven days from the end of the collection month to hand it over. You can estimate the collectible amount on a given transaction with the Oquilia TCS calculator, and compare it against a withholding scenario using the TDS calculator.

Statutory Deadlines

The single most important rule for sellers is the deposit window. Under Rule 37CA read with section 206C, tax collected in any month must be paid to the credit of the central government within seven days from the last day of that month. TCS collected during September 2026 was therefore due by 7 October 2026, and TCS collected during October 2026 must reach the government by 7 November 2026. There is no grace period built into the seven-day count, and the challan is filed electronically through ITNS 281.

Deposit is only half the obligation. Every collector must also file the quarterly TCS statement in Form 27EQ, and issue the TCS certificate in Form 27D to each buyer. The two obligations run on different clocks, which is where collectors most often slip. The table below sets out both deadlines across the financial year, as published in the Income Tax Department tax calendar.

For the quarter that just ended, the Form 27EQ statement for July-to-September 2026 fell due on 15 October 2026, and the matching Form 27D certificates must be issued to buyers by 30 October 2026. A collector who missed the 15 October filing now faces a running fee of Rs 200 per day under section 234E, capped at the total TCS of that quarter, plus a possible penalty of between Rs 10,000 and Rs 1,00,000 under section 271H for non-filing or filing with incorrect particulars.

Late deposit carries its own cost. Section 206C(7) charges simple interest at 1% per month, or part of a month, from the date the tax was collectible to the date it is actually paid. Because a "part of a month" counts as a full month, a deposit that slips even one day past the seventh attracts a full month's interest, so a seller who collects TCS on 2 October 2026 and pays on 8 November 2026 is charged interest for two months, not for the thirty-two days of actual delay. The next table summarises the three distinct consequences that stack on a defaulting collector.

Collectors should also note the Liberalised Remittance Scheme threshold, which moved with effect from 1 April 2025. TCS on foreign remittances under the scheme now applies above an annual threshold of Rs 10 lakh, raised from the earlier Rs 7 lakh, and no TCS is levied on remittances for education financed through a loan from a notified financial institution. For large remittances, buyers can map the cash-flow impact against their quarterly advance-tax instalments using the advance-tax calculator, since TCS paid is creditable against the final tax liability of the assessment year.

Market Events

There is no Reserve Bank of India rate decision scheduled for 16 October 2026. The Monetary Policy Committee last met on 5-7 October 2026 and raised the repo rate by 25 basis points to 5.50%, its first increase since February 2023, shifting the stance to "calibrated tightening". The RBI cited crude-oil volatility, a deficient monsoon and core inflation of 4.8% recorded in August 2026. The RBI monetary policy statement records the next MPC review as scheduled for 2-4 December 2026, so the near-term policy calendar is quiet and the cost of money for sellers who fund working capital through external benchmark-linked loans is now anchored to a 5.50% repo rate.

For the TCS ecosystem specifically, the market event that matters is administrative rather than monetary: the Income Tax Department's TRACES portal processes Form 27EQ statements filed up to 15 October 2026 and generates Form 27D certificates, which buyers then reconcile against their Form 26AS and Annual Information Statement. Any mismatch between the TCS a seller reports and the credit a buyer sees flows directly into the buyer's return for the 2027-28 assessment year, making the accuracy of the just-closed quarterly filing a live issue through the rest of October 2026.

Earnings

The tomorrow-watchlist briefing for 16 October 2026 carries no confirmed corporate results, and this report will not manufacture an earnings calendar. What sellers and their finance teams should watch instead is the interaction between the TCS cycle and the second-quarter reporting season that companies enter from mid-October. A listed entity that sells scrap, trades in specified minerals, or deals in motor vehicles above Rs 10 lakh must have deposited its September 2026 TCS by 7 October 2026 and filed Form 27EQ by 15 October 2026 before those collections are cleanly reflected in its books for the quarter ended 30 September 2026.

Where a company's own results are not yet public, the disciplined approach is to track the official filing record rather than rumour. No numeric earnings figure in this report is drawn from an unverified source, in keeping with the principle that a specific number must trace to an official release or statute. Investors building a position around a results date should size it through the Oquilia SIP calculator rather than around a single quarter's TCS-adjusted print.

FAQ

What is the seven-day deadline for depositing TCS?

Under Rule 37CA read with section 206C of the Income Tax Act 1961, a seller who collects TCS must deposit it with the central government within seven days from the end of the month in which it was collected. TCS collected in October 2026 is therefore due by 7 November 2026, and there is no grace period beyond the seventh.

What happens if I deposit TCS late?

Section 206C(7) charges simple interest at 1% for every month or part of a month of delay, running from the date the tax was collectible to the date it is paid. Because any part of a month counts as a full month, even a single day's delay past the seventh attracts a full month's interest.

When is Form 27EQ due for the July-to-September 2026 quarter?

The quarterly TCS statement in Form 27EQ for the quarter ended 30 September 2026 was due on 15 October 2026. Filing after that date attracts a fee of Rs 200 per day under section 234E, capped at the total TCS collected for the quarter, and a possible penalty of Rs 10,000 to Rs 1,00,000 under section 271H.

What is the difference between TCS and TDS?

TDS is tax withheld by the payer from a payment, whereas TCS is tax added by the seller on top of the sale price and collected from the buyer on specified transactions. Both are deposited with the government and both appear as credits in the recipient's Form 26AS and Annual Information Statement.

Does TCS apply to foreign remittances?

Yes. Under section 206C(1G), TCS applies to remittances under the Liberalised Remittance Scheme above an annual threshold of Rs 10 lakh, raised from Rs 7 lakh with effect from 1 April 2025. Remittances for education financed through a loan from a notified financial institution are not subject to this TCS.

Can I claim credit for TCS paid?

Yes. TCS collected from you is credited to your account and can be set off against your final income-tax liability for the relevant assessment year, with any excess refundable. You can model the effect on your instalments using the advance-tax calculator.

When must the TCS certificate in Form 27D be issued?

Form 27D must be issued to the buyer within fifteen days of the due date for filing Form 27EQ. For the quarter ended 30 September 2026, with the statement due on 15 October 2026, the Form 27D certificates must be issued to buyers by 30 October 2026.
