Why two provisions exist for one transaction
For decades, TDS mostly covered services, salaries and rent — plain goods trading stayed outside the net. The government then plugged that gap from both ends. First came Section 206C(1H), asking large sellers to collect a small tax (TCS) on receipts from goods sales. Then came Section 194Q, asking large buyers to deduct tax (TDS) on goods purchases.
The result: the same invoice can, on paper, fall under both. The law resolves this with a priority rule — 194Q wins. If the buyer is obliged to deduct TDS under 194Q, the seller should not collect TCS under 206C(1H) on that transaction. Understanding who carries the obligation is therefore mostly a matter of checking who crosses which threshold.
The two provisions side by side
| Section 194Q (TDS) | Section 206C(1H) (TCS) | |
|---|---|---|
| Who acts | The buyer deducts | The seller collects |
| On what | Purchase of goods from a resident seller | Receipt of sale consideration for goods |
| Size test | Buyer's own turnover in the previous year must exceed the prescribed limit (a crore-level figure — verify current numbers) | Seller's own turnover in the previous year must exceed the prescribed limit |
| Value trigger | Purchases from that seller crossing the annual per-party threshold; tax applies on the excess | Receipts from that buyer crossing the annual per-party threshold; tax applies on the excess |
| Timing | Credit of the purchase or payment, whichever is earlier | Actual receipt of money |
| Rate character | A fraction of a percent (nominal; check the current chart) | A fraction of a percent (nominal; check the current chart) |
| Reported in | Quarterly TDS statement (26Q family) | Quarterly TCS statement (27EQ) |
| Certificate | Form 16A to the seller | Form 27D to the buyer |
Both rates are deliberately tiny — these provisions exist to create a data trail in Form 26AS/AIS, not to raise serious revenue. But the compliance machinery (TAN, challans, quarterly statements) is exactly as real as for any other TDS. If you are new to that machinery, start with our TDS basics guide.
The decision path in practice
For any large goods transaction, walk this ladder:
- Is the buyer big enough for 194Q? If the buyer's previous-year turnover exceeds the prescribed limit and purchases from this seller cross the per-party threshold — the buyer must deduct TDS. The seller does nothing.
- Buyer not covered, but seller big enough for 206C(1H)? Then the seller collects TCS on receipts beyond the threshold.
- Neither crosses the limits? Nobody deducts or collects. Most small-business trades live here.
Practical tip: at the start of each financial year, exchange simple declarations with your major trading partners stating whether 194Q applies to you as a buyer. That one email prevents double taxation of the same invoice and awkward reconciliation later.
Worked example: ₹80 lakh of purchases from one supplier
Suppose Meera Traders (previous-year turnover well above the 194Q limit) buys goods worth ₹80,00,000 during the year from Sharma Steels. Assume the per-party threshold is ₹50,00,000 (verify the current figure) and an illustrative rate of 0.1%.
- Purchases up to ₹50,00,000 — no deduction.
- Excess of ₹30,00,000 — Meera Traders deducts 0.1% = ₹3,000 as TDS under 194Q.
- Meera deposits ₹3,000 against Sharma Steels' PAN, reports it quarterly, and issues Form 16A.
- Because 194Q applied, Sharma Steels does not collect TCS under 206C(1H) on these receipts — even if Sharma's own turnover would otherwise have triggered it.
Now flip it: if Meera Traders were a small buyer below the 194Q turnover test, and Sharma Steels were the large party, Sharma would add TCS on receipts beyond the threshold — collecting roughly the same nominal amount, but from the seller's side and on a receipt basis.
Common pitfalls to avoid
- Both sides acting. Buyer deducts TDS and seller collects TCS on the same invoice. The priority rule says 194Q prevails — coordinate with your counterparty.
- Forgetting it is per-party, per-year. The threshold is tested against cumulative purchases/receipts from each party in the financial year, not per invoice. Your books must track running totals supplier-wise — this is exactly the kind of running tally accounting software should maintain for you (see our iAccounting guides).
- GST confusion. Whether the threshold and the deduction base include GST has specific rules and clarifications — treatment differs between 194Q and 206C(1H) depending on timing of deduction. Check current CBDT guidance rather than assuming.
- Timing mismatch. 194Q triggers on credit/payment (accrual-friendly); 206C(1H) triggers only on money actually received. Advances can trigger obligations before the invoice exists.
- Missing PAN. As with all TDS/TCS, a missing PAN pushes the rate up sharply. Collect PANs from every large trading partner up front.
Recording it in your books
For the buyer under 194Q, the deduction sits as a "TDS payable" liability until the challan is paid; the seller sees it as a receivable against their tax liability. For TCS, the seller adds the collected amount to the invoice/receipt and holds it as "TCS payable". Our tutorial on journal entries (including TDS entries) shows the exact postings, and the TDS & TCS tutorial covers how these interact with GST-side TCS, which is a separate mechanism altogether.
The takeaway
One transaction, two mirror provisions, one priority rule: if the buyer must deduct under 194Q, the seller stands down on 206C(1H). Confirm turnover status with your counterparties annually, track per-party cumulative values through the year, and let your accounting software raise the flag when a supplier or customer crosses the threshold — because by the time you notice manually, you are usually already late.
