For businesses dealing in bulk goods, one of the most common compliance questions is: should the buyer deduct TDS under Section 194Q, or should the seller collect TCS under Section 206C(1H)?

This issue matters because both provisions can appear to apply to the same transaction. However, they are not meant to operate simultaneously on the same sale. In practice, businesses must identify who is liable, on which transaction, and at what threshold. A wrong classification can lead to short deduction, excess collection, notices, interest, and reconciliation issues in Form 26AS and AIS.

If you are managing procurement, accounting, or tax compliance, this guide will help you decide the correct treatment for Section 194Q 206C(1H) bulk business purchases 2026.

Section 194Q was introduced to shift tax collection responsibility to the buyer in specified high-value purchase transactions. Section 206C(1H), on the other hand, requires the seller to collect TCS on high-value sales. Since both provisions are designed for business-to-business trade in goods, confusion is natural.

The key point is simple:

  • Section 194Q applies to the buyer
  • Section 206C(1H) applies to the seller
  • If 194Q applies, 206C(1H) generally does not apply on the same transaction

In other words, the law tries to avoid double taxation at source on the same purchase/sale.

What Section 194Q says

Section 194Q requires a buyer to deduct TDS at 0.1% on the value of goods purchased from a resident seller, if:

  • the buyer’s turnover, gross receipts, or sales exceeded ₹10 crore in the preceding financial year, and
  • the purchases from that seller exceed ₹50 lakh in the financial year.

TDS applies only on the amount exceeding ₹50 lakh for each seller in a financial year.

What Section 206C(1H) says

Section 206C(1H) requires a seller to collect TCS at 0.1% on the sale consideration from a buyer, if:

  • the seller’s turnover exceeded ₹10 crore in the preceding financial year, and
  • the aggregate sales consideration from that buyer exceeds ₹50 lakh in the financial year.

Again, tax applies only on the amount above ₹50 lakh.

The important overlap rule

Where both provisions may technically appear applicable, Section 194Q overrides Section 206C(1H) for that transaction. So, if the buyer is liable to deduct TDS under 194Q, the seller should not collect TCS under 206C(1H) on the same sale.

This makes 194Q the primary compliance trigger in many B2B purchase situations.

Practical conditions to check first

Before deciding, check the following:

  • Is the transaction for goods and not services?
  • Is the seller resident?
  • Is the buyer a person covered by the threshold under 194Q?
  • Has the buyer crossed ₹10 crore turnover in the preceding FY?
  • Has the seller crossed ₹10 crore turnover in the preceding FY?
  • Has the ₹50 lakh threshold been crossed for that particular counterparty in the financial year?
  • Is the buyer already deducting TDS, which would block the seller from collecting TCS?

Important compliance interpretation

  • 194Q is buyer-based and applies first
  • 206C(1H) is seller-based and applies only if 194Q does not
  • Both provisions are meant for sale of goods
  • They do not generally apply to services, imports, or transactions involving non-resident parties, subject to specific factual review

GST and valuation note

For Section 194Q, where GST is shown separately in the invoice, TDS is generally computed on the amount excluding GST on the basis of CBDT guidance.

For practical compliance, businesses should ensure their ERP and accounts payable systems apply the provision consistently and in line with invoicing structure and tax advice.

Step-by-step guidance

Step 1: Identify whether the transaction is covered at all

Start with the nature of the supply:

  • Is it a purchase/sale of goods?
  • Is the counterparty a resident?
  • Is it a business transaction and not a personal or non-commercial purchase?

If the transaction is outside this scope, neither 194Q nor 206C(1H) will generally apply.

Step 2: Check the buyer’s turnover for Section 194Q

Ask this first:

  • Did the buyer’s turnover, sales, or gross receipts exceed ₹10 crore in the preceding FY?

If yes, the buyer may be liable under 194Q.

If no, 194Q does not apply, and you must then examine whether the seller can collect TCS under 206C(1H).

Step 3: Track seller-wise purchases against ₹50 lakh

For each resident seller, track the total purchases in the financial year.

  • Up to ₹50 lakh: no TDS under 194Q
  • Above ₹50 lakh: TDS applies on the excess amount

This must be monitored seller-wise, not on a combined vendor pool basis.

Step 4: If 194Q applies, stop TCS under 206C(1H)

Once buyer liability under 194Q is established:

  • the buyer deducts TDS
  • the seller should not collect TCS on that transaction

This is the most important operational rule for avoiding double deduction/collection.

Step 5: If 194Q does not apply, check seller liability under 206C(1H)

If the buyer is not covered by 194Q, then check whether the seller must collect TCS:

  • seller turnover must exceed ₹10 crore in the preceding FY
  • buyer-wise receipts must cross ₹50 lakh in the year

If yes, the seller collects TCS on the excess amount.

Step 6: Put controls in ERP and vendor onboarding

Businesses should not wait till year-end to fix this. Build controls such as:

  • vendor/customer declaration formats
  • PAN validation
  • turnover declaration for preceding FY
  • automatic threshold monitoring in ERP
  • tax code mapping for 194Q and 206C(1H)
  • monthly reconciliation with books and tax returns

Step 7: Reconcile TDS/TCS with Form 26AS and AIS

Because TDS and TCS reflect in the buyer’s and seller’s tax records, mismatch can lead to disputes.

Always reconcile:

  • books of account
  • vendor/customer ledger
  • Form 26AS
  • AIS/TIS
  • challans and quarterly returns

Examples

Example 1: Buyer liable under Section 194Q

A manufacturing company had turnover of ₹18 crore in FY 2025-26. It purchases raw materials from a resident supplier for ₹80 lakh during FY 2026-27.

  • Buyer turnover exceeds ₹10 crore → 194Q may apply
  • Purchases exceed ₹50 lakh → tax applies on ₹30 lakh
  • TDS @ 0.1% = ₹3,000
  • Seller should not collect TCS under 206C(1H)

This is the classic 194Q case.

Example 2: Seller collects TCS because 194Q does not apply

A trader had turnover of ₹7 crore in the preceding year. It buys goods from a resident seller whose turnover was ₹25 crore.

Since buyer turnover is below ₹10 crore:

  • 194Q does not apply
  • seller turnover exceeds ₹10 crore
  • if buyer’s purchases from that seller exceed ₹50 lakh, seller must collect TCS under 206C(1H)

If the sale consideration crosses ₹50 lakh, TCS is collected only on the excess.

Example 3: Both thresholds appear to be met, but 194Q wins

A dealer with turnover of ₹12 crore buys goods worth ₹2 crore from a resident supplier whose turnover is also above ₹10 crore.

At first glance, both provisions seem relevant. But the correct treatment is:

  • buyer deducts TDS under 194Q
  • seller does not collect TCS under 206C(1H)

This is where many businesses make reconciliation mistakes.

Example 4: Purchases below threshold

A company with turnover of ₹20 crore buys goods worth ₹45 lakh from a resident seller.

Even though the buyer is otherwise covered by 194Q:

  • the purchase amount has not crossed ₹50 lakh
  • no TDS is deducted yet

Once cumulative purchases from the same seller cross ₹50 lakh, TDS begins only on the excess.

Common mistakes

  • Assuming both 194Q and 206C(1H) apply together on the same transaction
  • Checking only current-year turnover instead of preceding FY turnover
  • Applying the threshold customer-wise instead of seller-wise under 194Q
  • Forgetting that the provisions are for goods, not services
  • Applying TCS even when the buyer has already deducted TDS under 194Q
  • Ignoring PAN availability and applying the wrong rate
  • Not excluding or separately accounting for GST in 194Q calculations where applicable
  • Failing to update ERP settings after crossing the ₹50 lakh threshold
  • Missing quarterly return reporting and therefore creating AIS/26AS mismatches
  • Treating one-time high-value purchases as outside TDS/TCS rules without checking aggregate turnover

Conclusion

For bulk business purchases in 2026, the decision is usually straightforward once you know the sequence:

  • First, check whether Section 194Q applies to the buyer
  • If yes, the buyer deducts TDS and the seller should not collect TCS
  • If 194Q does not apply, then test whether Section 206C(1H) applies to the seller

The most practical rule is this: 194Q has priority over 206C(1H) on the same goods transaction.

For tax teams, the real challenge is not just knowing the law, but building a system that tracks thresholds, counterparty turnover, and monthly cumulative purchases accurately. That is what prevents notices, disputes, and year-end reconciliation issues.

If your business is handling large-volume B2B procurement, a strong compliance checklist and vendor-wise monitoring process is essential. In most cases, the right answer is not complicated — but the data management behind it must be precise.
