GST TDS is a deduction made by specified recipients under section 51 of the CGST Act when its conditions, including the stated contract-value test, are met. Income-tax TCS on covered scrap sales is collected by the seller from the buyer. A private buyer does not become a GST TDS deductor merely because the goods are scrap. For transactions around 1 April 2026, identify whether the earlier credit or payment event falls under the Income-tax Act, 1961 or the Income-tax Act, 2025 before applying a section, rate or threshold.
The short answer: two mechanisms, two parties, two statutes
Scrap transactions often create confusion because a tax amount may appear on the same invoice or payment record, yet the legal mechanism can be entirely different. GST TDS is a payment deduction made by an eligible recipient. Income-tax TCS is a collection made by the seller on a covered sale. They do not use the same trigger, base, reporting system or statutory purpose.

| Point | GST TDS | Income-tax TCS on scrap |
|---|---|---|
| Primary law | Section 51 of the CGST Act, with applicable GST rules and notifications | For events governed by the earlier law, the Income-tax Act, 1961; from 1 April 2026, section 394 of the Income-tax Act, 2025 |
| Who acts | A specified recipient (the deductor) deducts from a payment to the supplier | The seller or other statutory collector collects from the buyer |
| Basic trigger | Specified deductor category plus the section 51 conditions; CBIC’s FAQ describes a contract value above ₹2.5 lakh, excluding GST, for the rule explained there | A sale of scrap that falls within the operative income-tax provision, definitions, exclusions and any applicable thresholds |
| Is every scrap purchase covered? | No. The buyer’s identity and contract conditions matter | No. The sale must satisfy the current TCS provision |
| Tax context | A GST payment-deduction mechanism; it does not by itself decide whether the supply is taxable or which GST rate applies | An income-tax collection on the buyer’s possible income-tax liability, not a tax on the goods themselves |
| 2026 transition | GST section 51 continues to be assessed under GST law | Use the Income-tax Act determined by the earlier of credit or payment; post-transition TCS references are in section 394 of the 2025 Act |
First correct the terminology: “income-tax TDS on scrap” usually means TCS
TDS and TCS are not interchangeable labels. In a TDS transaction, the person making a specified payment deducts tax before paying the recipient. In a TCS transaction, the seller collects an amount from the buyer in connection with a covered sale. The scrap-sale rule discussed here is an income-tax tax collection at source rule, so the seller is normally the relevant collector.
That distinction answers the common question “Who deducts TDS on scrap, buyer or seller?” For GST TDS, an eligible recipient can be the deductor. For income-tax scrap TCS, the seller collects from the buyer when the statutory conditions are met. Calling both amounts “TDS” can send the payment to the wrong compliance workflow.

When GST TDS applies to a scrap transaction
1. Check the buyer’s legal identity first
Section 51 is not a universal rule for every commercial buyer. CBIC describes specified deductor categories such as government departments, local authorities, governmental agencies and other notified categories. The identity of the recipient making the payment is therefore the first test.
A private manufacturer, recycler or trader buying scrap is not automatically required to deduct GST TDS merely because the purchase is from a business or because the invoice includes GST. If the buyer is not within a specified category, the section 51 deduction does not arise on that fact alone.
2. Apply the contract-value condition
For the rule described in CBIC’s Sectoral FAQs, the total contract value must be above ₹2.5 lakh, excluding GST. This is a contract-value test, not a claim that every individual invoice over ₹2.5 lakh creates GST TDS. Review the contract, purchase order and any aggregation rule in the applicable GST provisions before deciding.
The exclusion of GST from the stated threshold is important. Do not compare the threshold with an invoice total that includes the GST component and then treat that inclusive figure as the statutory value without adjustment.
3. Confirm that there is a qualifying payment to a supplier
Section 51 operates as a deduction from payment to a supplier. The contract and payment must be examined against the operative GST rules, notifications and exceptions. A scrap item being sold in the course or furtherance of business can be a GST supply, but that fact alone does not make the buyer a section 51 deductor.
4. Keep GST TDS separate from the underlying GST supply
CBIC’s FAQ states that disposal of scrap in the course or furtherance of business is a supply. That conclusion does not, by itself, settle the classification, applicable rate, place of supply, valuation or every transaction-specific issue. Determine those GST questions independently from the TDS question.
A practical GST TDS decision sequence
- Identify the entity making the payment and check whether it is a specified section 51 deductor.
- Read the contract or purchase order and calculate the relevant value excluding GST; compare it with the stated ₹2.5 lakh threshold.
- Check the applicable GST rules, notifications and exclusions for the payment and supplier relationship.
- Calculate and record any deduction using the rate and procedure in force for the transaction date; do not copy a rate from an outdated checklist.
- Reconcile the deduction with the GST records, supplier documentation and the prescribed GST reporting or certificate process.
How income-tax TCS on scrap works
The seller collects; the buyer pays the collected amount
Where the current income-tax scrap provision applies, the seller collects TCS from the buyer in addition to the commercial sale consideration as required by law. The buyer should not describe this seller-side collection as GST TDS. The seller must determine whether it is the statutory collector, whether the goods meet the legal definition of scrap and whether the transaction falls within the applicable exclusions and thresholds.

“Scrap” in ordinary business language is broader than a tax definition. Materials, processing status, the seller’s business and statutory exclusions can affect the result. Before collecting, check the operative provision and its definitions for the transaction date. The official material confirms that scrap is included among TCS reporting categories, but it does not establish a single current rate or threshold for every 2026 transaction.
Do not infer a 2026 rate from an old invoice or guide
For a post-transition event, the relevant TCS provisions are in section 394 of the Income-tax Act, 2025. The exact operative section 394 table entry for scrap must be checked in the current statute or official guidance before issuing an invoice, collecting money or correcting a return. If a source only shows an earlier rate, treat it as historical unless it expressly covers the transaction date and governing Act.
Reporting and credit
The Income Tax Department’s Form 143 user manual includes scrap among TCS reporting categories and describes the quarterly statement schedule. A seller collecting TCS should preserve the buyer’s details, sale documents, collection amount, deposit evidence and statement data so the buyer can reconcile the credit. The reporting form does not convert the collection into GST TDS; it remains an income-tax process.
Why CBIC says income-tax TCS is not GST on the scrap
CBIC’s 7 March 2019 corrigendum to Circular No. 76/50/2018-GST explains the relationship between the two systems. It states: “Tax collection at source (TCS) is not a tax on goods but an interim levy on the possible ‘income’ arising from the sale of goods by the buyer and to be adjusted against the final income- tax liability of the buyer.”

Accordingly, assess the GST value and GST rate under GST law, while treating income-tax TCS as a separate collection. Do not automatically add the income-tax TCS amount to the value of the goods for GST merely because it appears on the same invoice. The exact valuation result depends on the transaction and the applicable GST provisions; the two taxes should be shown and reconciled separately.
Can both mechanisms appear in one scrap transaction?
Yes, but only if each system’s independent conditions are satisfied. Consider a government entity purchasing business scrap under a contract that exceeds the GST threshold excluding GST. The recipient may have a GST TDS obligation because of its specified status and contract conditions. Separately, the seller may have an income-tax TCS obligation if the scrap sale meets the current income-tax rule. One amount is deducted by the eligible recipient; the other is collected by the seller.
| Scenario | GST TDS question | Income-tax TCS question |
|---|---|---|
| Private company buys scrap from a manufacturer | Is the company a specified section 51 deductor, and is the contract within the qualifying threshold? | Is the seller collecting on a covered scrap sale under the current income-tax provision? |
| Government department buys under a large contract | Check specified-deductor status and the contract value excluding GST | Check whether the seller and goods meet the current TCS conditions |
| Several invoices under one purchase order | Review total contract value and applicable aggregation rules; do not test only one invoice in isolation | Review each sale and the statutory collection conditions, including any exclusions |
| Transaction spans 31 March and 1 April 2026 | Apply GST section 51 rules and the relevant GST dates | Identify the earlier credit/payment event to select the 1961 or 2025 Income-tax Act |
The 1 April 2026 transition: use the earlier of credit or payment
The Income Tax Department’s transition guidance uses the earlier of credit or payment to determine which Income-tax Act governs a TDS or TCS event. An event with the relevant earlier event on or before 31 March 2026 is governed by the Income-tax Act, 1961. An event whose earlier credit/payment event is on or after 1 April 2026 is governed by the Income-tax Act, 2025.
| Earlier relevant event | Governing income-tax law | Practical action |
|---|---|---|
| Credit or payment on or before 31 March 2026 | Income-tax Act, 1961 | Use the applicable pre-transition provision and documentation, subject to the law in force for that event |
| Credit or payment on or after 1 April 2026 | Income-tax Act, 2025 | Use section 394 for TCS and verify the current scrap entry, rate, threshold and exclusions |
| Credit before 1 April, payment after 1 April | The earlier credit event points to the 1961 Act under the stated transition test | Retain evidence of the credit date and do not change the governing Act solely because cash moved later |
| Payment before 1 April, credit after 1 April | The earlier payment event points to the 1961 Act under the stated transition test | Document the payment date and apply the corresponding reporting treatment |
For post-transition records, avoid labelling a 2026–27 event with an old section number just because a template, invoice or software screen has not been updated. The Department identifies section 393 as the TDS provision and section 394 as the TCS provision in the 2025 Act.
Buyer checklist
- Classify the amount correctly: GST TDS deduction by an eligible recipient is not seller-side income-tax TCS.
- Confirm whether your entity is a specified GST TDS deductor; do not assume that buying scrap is enough.
- For the CBIC threshold described, calculate contract value excluding GST and test the ₹2.5 lakh condition.
- Ask the seller whether an income-tax TCS collection is required, and verify the current statutory basis rather than accepting an unexplained line item.
- For an event near 1 April 2026, record the credit and payment dates and apply the earlier-event transition rule.
- Reconcile GST TDS records and income-tax TCS credit separately in your ledgers and returns.
Seller checklist
- Determine whether disposal of the material is a GST supply in the course or furtherance of business and complete the separate GST classification and valuation analysis.
- Check whether the buyer is a specified GST TDS deductor and whether the contract test is met; the seller should not treat every buyer’s deduction request as legally valid.
- For income-tax TCS, verify the legal definition of scrap, seller status, buyer details, exclusions and the provision applicable on the credit/payment date.
- Do not use an old TCS rate or threshold for a post-1 April 2026 event without checking section 394 and its operative table.
- Report collections through the prescribed income-tax statement process, including the Form 143 category where applicable, and retain supporting sale and collection records.
- Show GST amounts and income-tax TCS distinctly enough for both parties to reconcile them.
Common errors and how to correct them
“Every scrap buyer must deduct GST TDS.”
Why it fails: Section 51 depends on the deductor’s specified status and the qualifying conditions. Correction: start with the buyer’s legal category, then test the contract value excluding GST.
“The seller deducts income-tax TDS from the buyer.”
Why it fails: the scrap rule is generally a TCS collection. Correction: record the seller as collector and the buyer as the person from whom the collection is made, subject to the statutory conditions.
“TCS is part of the GST value because it is printed on the invoice.”
Why it fails: CBIC describes income-tax TCS as an interim levy against possible income-tax liability, not a tax on goods. Correction: determine GST valuation under GST law and account for income-tax TCS separately.
“The 2025 Act applies whenever cash is paid after 1 April 2026.”
Why it fails: the transition test uses the earlier of credit or payment. Correction: preserve both dates and apply the Act selected by the earlier event.
“An old website’s scrap rate is safe for 2026.”
Why it fails: rates, thresholds, definitions and section numbering are date-sensitive. Correction: verify the operative section 394 entry and current official guidance before collecting or remitting.
A compact decision tree
- Is the transaction a business disposal of scrap? If yes, analyze it as a potential GST supply; this does not decide TDS or TCS by itself.
- Is the payment recipient a specified GST TDS deductor? If no, section 51 GST TDS is not triggered merely by the scrap purchase.
- Is there a qualifying contract above ₹2.5 lakh excluding GST under the applicable GST rule? If no, the CBIC threshold described is not met; check other applicable rules before closing the analysis.
- Is the seller required to collect income-tax TCS on this scrap sale? Check the current definition, exclusions, threshold and transaction date.
- Did the earlier credit or payment occur on or after 1 April 2026? If yes, use the 2025 Act framework and section 394 for TCS; verify the exact scrap entry before using a rate or threshold.
- Are both amounts present? Keep the GST TDS deduction and income-tax TCS collection as separate statutory records and reconciliations.
What to verify before filing or paying
For a transaction-specific conclusion, assemble the contract, invoice, GST registration details, buyer’s legal status, seller’s business activity, material description, credit date, payment date and any exemption or exclusion relied upon. Then check the current CBIC GST guidance and the Income Tax Department’s operative provisions for the relevant period. If the amount is material or the dates straddle the transition, obtain professional advice based on the actual documents rather than relying on a generic invoice label.
Bottom line
GST TDS is a limited, buyer-side payment deduction under GST section 51 for specified recipients and qualifying contracts. Income-tax TCS on scrap is a seller-side collection under the applicable income-tax law. A scrap purchase can involve one, both or neither mechanism. Decide separately who is legally responsible, which threshold and tax base apply, and which Income-tax Act governs the earlier credit/payment event. For events from 1 April 2026 onward, verify the current section 394 scrap entry instead of carrying forward an older rate or section number.
