An Indian Tier-1 auto component supplier closes its monthly books at the intersection of four independent statute streams that must reconcile simultaneously. Section 194Q of the Income-tax Act 1961 requires 0.1% buyer-side TDS on the Tier-1's own Tier-2 purchases aggregating above ₹50 lakh per seller PAN per FY (the Tier-1 as deductor), and simultaneously delivers a 0.1% own-account TDS credit into Form 26AS from every OEM sale above the same threshold (the OEM as deductor on the Tier-1's invoices). CBDT Circular 13 of 2021 resolves the potential double tax at the OEM-to-Tier-1 interface by giving Section 194Q precedence over Section 206C(1H). Ind AS 37 requires a constructive warranty provision on the OEM pass-through obligation embedded in the master supply agreement, discounted to present value where the beyond-12-month leg is material, split into current and non-current buckets on the balance sheet. Rule 37 of the CGST Rules 2017 triggers ITC reversal on any Tier-2 payables unpaid beyond 180 days, cross-tied to the OEM receivables ageing that produced the payment delay. Getting all four streams to reconcile on the same close is the difference between a clean statutory audit and material Section 201, Section 271C, and GST assessment exposure.
Route every Tier-2 vendor through a 194Q applicability check at onboarding based on the vendor's PAN, its preceding-FY turnover declaration on Form 26Q, and the running FY aggregate purchase — the 0.1% deduction fires the moment the ₹50 lakh threshold is crossed on the cumulative. Route every OEM customer through a 194Q-deductor tag in the customer master — the invoice generator suppresses 206C(1H) collection where the tag is on, prints the information note acknowledging the OEM's 194Q obligation, and books the receivables-side TDS credit into a Form 26AS reconciliation queue at the following quarter. Recognise the Ind AS 37 warranty provision at part dispatch under the constructive-obligation trigger, at 1% to 3% of trailing twelve-month OEM billing per part family and per OEM, discounted to present value at the RBI G-Sec zero-coupon rate for the beyond-12-month leg where material, refreshed quarterly against actual FOMP claim closure. Monitor Tier-2 payables age from invoice date daily, fire the Rule 37 ITC reversal in GSTR-3B the tax period after the 180-day boundary, cross-tag to the OEM receivables ageing that explains the delay, and re-credit on subsequent supplier payment.
Vendor master with PAN, preceding-FY turnover declaration, 194Q-applicability flag, and FY-to-date aggregate purchase ledger with the ₹50 lakh threshold trigger. Customer master with 194Q-deductor tag (typically ON for every private-OEM customer, OFF for state-body customers under the Section 194Q(3)(a) exemption). Invoice generator with conditional 206C(1H) collection logic driven off the customer-master tag and CBDT Circular 13 of 2021 precedence rule. Section 393 payment-code table mapping Section 194Q to code 1090 under the Income-tax Act 2025 successor regime. Ind AS 37 provision model per part family and per OEM with historical FOMP run rate as the reliable-estimate base, RBI G-Sec zero-coupon curve for discounting, and Schedule III Division II current/non-current split at the reporting date. Rule 37 ITC reversal engine with per-invoice payables age tracker, 180-day trigger, GSTR-3B reversal line generator, and re-credit workflow on subsequent payment. Monthly close: Form 281 challan deposit by the 7th of the following month, Form 26Q quarterly return with per-seller-PAN payment-code breakup, Form 26AS ingestion for receivables-side own-account credit matching, GSTR-3B Rule 37 reversal register.
A per-Tier-2-vendor Section 194Q ledger showing FY-to-date purchase value, 0.1% deduction on the portion above ₹50 lakh, challan deposited, Form 26Q reported, and vendor-side Form 26AS credit acknowledged. A per-OEM receivables-side own-account TDS credit ledger showing OEM sale invoice value, 194Q credited at 0.1% by the OEM in Form 26AS, matched to the Tier-1's income-tax return credit claim, with 206C(1H) suppression audit note. An Ind AS 37 warranty provision roll-forward by quarter with the opening balance, provision addition at 1% to 3% of trailing OEM billing, claim settlement drawdown, discount unwind on the non-current leg, and closing balance split into current and non-current per Schedule III. A Rule 37 ITC reversal register with per-invoice payables age band, 180-day breach flag, GSTR-3B reversal amount, interest under Section 50, and re-credit on subsequent payment. An audit-ready evidence pack anchoring each 194Q deduction to CBDT Circular 13 of 2021 precedence, each warranty provision to Ind AS 37 paragraph 14 recognition criteria, and each Rule 37 reversal to the underlying invoice-age trigger.
A Chennai-headquartered Tier-1 auto component supplier — ₹1,240 crore FY revenue across braking systems, transmission assemblies and steering columns, with Maruti Suzuki, Tata Motors, Mahindra and Mahindra and Hyundai as the four active OEM accounts — closes its August 2026 monthly books and pulls the compliance cross-check. On the payables side, 218 active Tier-2 vendor PANs, 47 of which have crossed the ₹50 lakh aggregate FY threshold requiring Section 194Q 0.1% deduction from July onward, 6 of which crossed in August and require a retroactive-shortfall correction on the July invoices that went out without deduction. On the receivables side, the four OEMs have collectively deducted ₹1.24 crore of Section 194Q on the Tier-1’s invoices for the twelve trailing months and the Tier-1’s Form 26AS shows ₹1.11 crore acknowledged so far — a ₹13 lakh reconciliation gap that maps to a June-quarter Form 26Q filing that one of the OEMs deferred. In the balance-sheet accounts, the Ind AS 37 warranty provision opening balance is ₹43.2 crore, an August provision addition at 2.1% of trailing OEM billing adds ₹2.17 crore, claim settlement drawdown against confirmed FOMP debits nets ₹1.86 crore, discount unwind on the non-current leg adds ₹18.4 lakh, and the closing balance of ₹43.68 crore splits into ₹18.4 crore current and ₹25.28 crore non-current per Schedule III Division II. And on the GST side, 14 Tier-2 payables have crossed the Rule 37 180-day boundary requiring an ITC reversal of ₹92 lakh in the September GSTR-3B with interest under Section 50. This is TDS 194Q auto OEM Tier-1 supplier warranty Ind AS 37 India at production scale — and getting the four independent statute streams to reconcile on the same close is what separates the audit-ready supplier from the one that carries material Section 201 and GST assessment exposure into the year-end statutory audit.

What the Tier-1 supplier’s monthly close intersection actually looks like
The Indian Tier-1 auto component supplier operates at a distinctive four-statute intersection that shows up on the same monthly close. The payables side runs Section 194Q as a buyer against every Tier-2 vendor whose aggregate FY purchase crosses ₹50 lakh. The receivables side runs Section 194Q in the mirror — the Tier-1 is now the seller, and every private OEM buyer deducts 0.1% at credit or payment (whichever is earlier) on the Tier-1’s invoice value above the same ₹50 lakh aggregate. On the balance-sheet accounts, the Ind AS 37 warranty provision runs against the constructive obligation the master supply agreement creates through the OEM pass-through mechanism. On the GST accounts, Rule 37 of the CGST Rules 2017 fires an ITC reversal on any Tier-2 payable unpaid beyond 180 days from invoice.
The interlocks between these four streams are what make the close operationally hard. The receivables-side own-account Section 194Q credit into Form 26AS must match the Tier-1’s own income-tax return credit claim, but the OEM’s quarterly Form 26Q filing timing (24 hours to 15 days lag against the deduction month is normal, longer under OEM-side reporting delays) means the credit trail is inherently lagged. The payables-side Rule 37 exposure is directly caused by the OEM receivables squeeze — OEMs typically stretch Tier-1 payment cycles to 90 to 120 days on standard terms and further under discretionary DPO management, which pushes the Tier-1’s own Tier-2 payables into the 180-day danger zone. The warranty provision quantum is a rolling function of the same OEM billing that generates the receivables-side 194Q credits, and the discount unwind on the non-current leg becomes a P&L finance-cost line that no OEM will reimburse.
Section 194Q — the 0.1% deduction and the ₹50 lakh aggregate FY threshold
Section 194Q was introduced by the Finance Act 2021 with effect from 1 July 2021 and requires any person, being a buyer whose preceding-FY total sales, gross receipts or turnover exceeds ₹10 crore, to deduct 0.1% tax at source on any sum paid or credited to a resident seller for purchase of goods where the aggregate FY purchase from that seller crosses ₹50 lakh. The deduction is on the sum exceeding ₹50 lakh — the first ₹50 lakh of a specific seller PAN’s aggregate is a free threshold, and 0.1% applies from the ₹50 lakh-and-first-rupee upward. Deduction is at the earlier of credit-to-vendor or payment-to-vendor, deposit is via Form 281 challan by the 7th of the following month (30 April for March deductions), and the quarterly return is Form 26Q under the Income-tax Act 1961 (migrating to Form 168 under the Income-tax Act 2025 for entries from the new-Act commencement date onward).
For a Tier-1 auto component supplier with FY revenue routinely in the ₹400 crore to ₹2,000 crore range, the ₹10 crore preceding-FY turnover eligibility is cleared many times over and the Section 194Q obligation as a buyer is a default-on posture on the entire Tier-2 vendor master. The operational discipline is a per-vendor-PAN FY-to-date purchase ledger that refreshes with each invoice booking, an aggregate-crossing trigger that fires the 0.1% deduction from the ₹50 lakh point forward, and a retroactive-shortfall workflow when the aggregate crosses mid-month against a set of invoices already paid or credited without deduction in the same FY. Missing-PAN cases escalate to 5% under Section 206AA(3) — the special 194Q escalation rate, which is lower than the general 20% Section 206AA(1) rate but still fifty times the standard 0.1%.
Section 194Q vs Section 206C(1H) — CBDT Circular 13 of 2021 mutual-exclusion drill
The Tier-1’s receivables side against a private OEM creates a structural overlap between two independent statute streams. The OEM as buyer independently triggers Section 194Q (preceding-FY turnover well above ₹10 crore, aggregate purchase from the Tier-1 easily above ₹50 lakh). The Tier-1 as seller independently triggers Section 206C(1H) (preceding-FY turnover above ₹10 crore, sale consideration from the OEM easily above ₹50 lakh). Absent a tie-breaker, the same 0.1% base would attract both a 194Q deduction by the OEM and a 206C(1H) collection by the Tier-1 — a double tax on the same transaction.
Paragraph 4.9.4 of CBDT Circular 13 of 2021 dated 30 June 2021 is the operative tie-breaker. It clarifies that where a transaction is both within the purview of Section 194Q and Section 206C(1H), Section 194Q takes precedence — the buyer deducts, and once the buyer has deducted, the seller is not required to collect under Section 206C(1H) on the same transaction. Section 194Q(3)(b) of the Income-tax Act 1961 read with this circular is the statutory-plus-clarificatory basis for the precedence rule.
The operational drill for the Tier-1 is a per-OEM tag in the customer master indicating whether the OEM is a 194Q deductor. For every private OEM in India — Maruti Suzuki, Tata Motors, Mahindra and Mahindra, Hyundai, Toyota Kirloskar, Kia, Skoda, Volkswagen, Nissan, Renault, MG Motor, Ashok Leyland, Bajaj Auto, TVS Motor, Hero MotoCorp, Royal Enfield — the tag is ON. The invoice generator suppresses 206C(1H) collection on the invoice, prints a compact information note acknowledging the OEM’s 194Q obligation, and the receivables-side workflow ingests the OEM’s TDS deduction as own-account credit at the following Form 26AS refresh.
The exception lane is where the buyer is a Central or State Government body, an embassy, a local authority, or a Central-Government-notified person under Section 194Q(3)(a). A Tier-1 selling to MSRTC or KSRTC for a state transport bus fleet, to a state police vehicle procurement, or to a municipal corporation for a solid-waste-management vehicle order sits in this exception lane — the state buyer does not deduct Section 194Q by virtue of the government-body exemption, the tie-breaker of CBDT Circular 13 of 2021 is therefore not engaged, and the Tier-1’s Section 206C(1H) collection obligation as seller re-activates on the invoice. The customer-master tag must accordingly flip from suppressed-206C(1H) on private-OEM sales to active-206C(1H) on state-body sales, and the invoice generator’s conditional logic must respect the flip.
The full boundary discussion including the ambiguous mid-year OEM turnover cases is at auto component TDS/TCS cross-era reconciliation.
Ind AS 37 warranty provision — constructive obligation, discounting, current/non-current split
Ind AS 37 paragraph 14 requires recognition of a provision when three tests are cleared simultaneously — the entity has a present obligation (legal or constructive) as a result of a past event, settlement is probable, and the amount can be reliably estimated. For a Tier-1 auto component supplier, all three tests are cleared at the moment a manufactured part is dispatched to the OEM.
The present-obligation test is met on the constructive-obligation leg, not the legal-obligation leg. The direct legal obligation the OEM holds is towards the end-vehicle retail buyer under the OEM’s own warranty — the Tier-1 is not in privity of contract with that retail buyer. But the master supply agreement between the OEM and the Tier-1 embeds a warranty pass-through — the OEM has the contractual right to raise a FOMP (Field-of-Market-Performance) debit note on the Tier-1 when a warranty-covered field failure at the retail buyer traces back to a component in the Tier-1’s dispatched batches. That pass-through, coupled with the industry-wide operating pattern of consistent FOMP debits from every major OEM on every major Tier-1, creates the constructive obligation. The past-event trigger is the dispatch — once the part is at the OEM and has been incorporated into a vehicle that has been sold to a retail buyer, the constructive obligation crystallises.
The probable-outflow test is met because the FOMP debit regime is historically observable and predictable — every Tier-1 with material OEM exposure carries a FOMP run rate. The reliable-estimate test is met by the historical run rate — typically 1% to 3% of trailing twelve-month OEM billing at the entry point, refreshed quarterly against actual claim closure trended by OEM, by part family and by warranty period.
Ind AS 37 paragraph 45 requires discounting to present value where the effect of the time value of money is material. For a Tier-1 supplying components under a 24-month or 36-month OEM warranty (which covers most passenger-vehicle Tier-1s, and increasingly light-commercial-vehicle Tier-1s), the beyond-12-month leg of the provision is 40% to 60% of the total exposure and the discounting effect is material. The discount rate is the pre-tax risk-free rate for the period matching the expected settlement — the RBI-published G-Sec zero-coupon yield curve at the reporting date for the corresponding tenor is the market-observable proxy the Big Four audit teams uniformly accept. The unwind of the discount period-by-period is recognised as a finance cost in the P&L, and Schedule III Division II presentation splits the discounted provision between current (settlement expected within twelve months) and non-current (beyond twelve months) buckets on the balance sheet.
The related FOMP claim-lifecycle mechanics — 8D response window, Section 34 GST credit-note timing, Tier-2 passthrough recovery — are at FOMP warranty back-charge accounting and the GST-on-warranty-replacement analysis is at GST on warranty replacements.
Rule 37 CGST Rules 2017 — ITC reversal on Tier-2 payables unpaid beyond 180 days
Rule 37 of the CGST Rules 2017 read with the second proviso to Section 16(2) of the CGST Act 2017 requires a registered person who has availed ITC on an inward supply but has not paid the supplier the value of the supply together with the tax within 180 days from the invoice date to reverse the availed ITC together with interest under Section 50, in the GSTR-3B for the tax period immediately following the 180-day expiry. Re-credit is available on subsequent payment to the supplier without any time limit for re-availment, so the reversal is not a permanent loss but the cash-flow drag of the reversed ITC and the interest under Section 50 is real.
For a Tier-1 auto component supplier the Rule 37 trigger is a lagging function of the OEM receivables squeeze. When an OEM stretches the Tier-1’s payment cycle from a contractual 60 or 90 days out to 120 or 150 days under discretionary DPO management (a common pattern at Indian OEMs across the quarter-end quarters), the Tier-1’s own payment discipline against Tier-2 vendors compresses in parallel — and any Tier-2 invoice that slips past the 180-day boundary triggers a Rule 37 reversal on the ITC the Tier-1 already claimed on that Tier-2 invoice, even though the Tier-1’s downstream GST liability on the OEM sale has already been paid.
The reconciliation platform therefore holds a per-invoice payables age tracker on every Tier-2 line, fires the 180-day trigger the first day of the tax period after the boundary, populates the Rule 37 reversal line in the GSTR-3B, computes the interest under Section 50 from the ITC availment date to the reversal date, and cross-tags the reversal to the specific OEM receivables ageing that produced the payment delay. On subsequent payment the re-credit workflow re-avails the reversed ITC in the corresponding tax period’s GSTR-3B, closes the reversal register entry, and reconciles to the Tier-2 vendor’s Form GSTR-1 reporting for the same invoice.
Worked example — a Tier-1 supplier’s ₹220 crore FY sales to one OEM with warranty accrual walk
The Chennai Tier-1 in the opening paragraph runs the annualised compliance walk for its Maruti Suzuki account — one of four active OEM accounts, delivering brake-caliper assemblies and steering-column intermediate shafts at aggregate ₹220 crore FY invoicing.

- Corresponding annualised Tier-2 procurement supporting the Maruti account: ₹130,00,00,000 across 84 active vendor PANs
- Vendors crossing ₹50 lakh aggregate FY threshold: 31
- Base for 194Q at Tier-1 side (aggregate excess above ₹50 lakh per vendor PAN): ₹114,20,00,000
- 194Q deducted by Tier-1 at 0.1%: ₹11,42,000
- Deposited via Form 281 challan by 7th of following month
- Reported in quarterly Form 26Q with per-vendor-PAN payment-code breakup (code 1090 under Act 2025 successor regime)
Ind AS 37 warranty provision walk on the ₹220 crore OEM sales:
- Trailing twelve-month OEM billing base: ₹220,00,00,000
- Historical FOMP run rate for the brake-caliper part family at Maruti: 2.1%
- Historical FOMP run rate for the steering-column intermediate shaft part family at Maruti: 1.4%
- Weighted-average provision rate: 1.9%
- Undiscounted provision: ₹4,18,00,000
- Expected settlement pattern per historical claim-age curve: 55% within 12 months, 45% beyond 12 months (weighted-average 22 months for the beyond-12-month leg)
- Current leg (12-month settlement): ₹2,29,90,000, no discounting
- Non-current leg (beyond-12-month settlement, weighted-average 22 months): ₹1,88,10,000 undiscounted
- RBI G-Sec zero-coupon rate at reporting date for 22-month tenor: 7.15%
- Discount factor for 22 months at 7.15%: 0.879
- Non-current leg at present value: ₹1,65,34,000
- Total Ind AS 37 warranty provision at reporting date: ₹3,95,24,000
- Schedule III Division II split: Current ₹2,29,90,000, Non-current ₹1,65,34,000
- Discount unwind next quarter recognised as finance cost in P&L: approximately ₹5,90,000 per quarter on the non-current leg
Rule 37 ITC reversal exposure on Tier-2 payables:
- Tier-2 procurement above unpaid past 180 days as at reporting date: ₹9,20,00,000
- ITC availed on this base at weighted-average 18% GST: ₹1,65,60,000
- Rule 37 reversal in following-tax-period GSTR-3B: ₹1,65,60,000
- Interest under Section 50 at 18% p.a. from ITC availment date to reversal date (weighted-average lag of 210 days): approximately ₹17,15,000
- Re-credit on subsequent Tier-2 payment: recovered as ITC availment in the corresponding tax period’s GSTR-3B, no interest recovery
Consolidated reconciliation position:
- Own-account 194Q credit into Form 26AS (receivables side): ₹21,95,000 claim in Tier-1’s income-tax return
- Payables-side 194Q deposit to Government (Tier-1 as deductor): ₹11,42,000 via Form 281
- Ind AS 37 warranty provision on balance sheet: ₹3,95,24,000 (current ₹2,29,90,000 + non-current ₹1,65,34,000)
- Rule 37 GSTR-3B reversal exposure this tax period: ₹1,65,60,000 plus interest ₹17,15,000
- 206C(1H) suppression net-out: ₹0 (suppressed under CBDT Circular 13 of 2021 precedence rule)
Cross-audit points:
- The receivables-side ₹21,95,000 194Q credit into Form 26AS must reconcile against the OEM’s quarterly Form 26Q filing; a lag of one quarter is normal, longer indicates an OEM-side reporting delay that the Tier-1 must flag proactively.
- The payables-side 47 vendors that crossed the ₹50 lakh threshold across the FY need retroactive-shortfall corrections on any pre-threshold invoices where deduction was skipped in the same FY, with interest under Section 201(1A) on the shortfall period.
- The Ind AS 37 provision discount rate must be refreshed at every reporting date against the current RBI G-Sec curve; a stale rate creates an audit finding at the year-end statutory audit.
- The Rule 37 reversal register cross-tags to OEM receivables ageing per Tier-2 invoice — the cross-tag is the evidence that the delay was working-capital-driven, not attempted-fraud-driven, and stands up under GST audit scrutiny.
The Form 26AS-side reconciliation drill including the OEM lag pattern is at Form 26AS reconciliation for auto component supplier.
Common reconciliation breakages
- Section 194Q payables-side threshold trigger missed on mid-year crossing — the AP system books invoice-by-invoice without a per-vendor-PAN aggregate FY ledger, and when a Tier-2 vendor crosses the ₹50 lakh aggregate mid-year, the retroactive-shortfall correction on the pre-threshold invoices is skipped, surfacing at Section 201 assessment with interest under Section 201(1A) and penalty under Section 271C exposure.
- 206C(1H) collected on OEM invoice despite 194Q precedence — the invoice generator defaults to 206C(1H) collection on every above-threshold buyer without the customer-master 194Q-deductor tag, double-taxing the transaction, forcing the OEM to demand a Section 34 credit note reversal, and creating a reconciliation break at the Tier-1’s quarterly Form 27EQ TCS return.
- Ind AS 37 provision not discounted despite material beyond-12-month leg — the provision is computed at undiscounted face value even where the non-current leg is 40% or more of the total exposure, overstating the balance-sheet liability, understating the P&L operating profit, and attracting an audit finding at the year-end statutory audit; discount-rate refresh discipline at each reporting date is the standard fix.
- Rule 37 ITC reversal skipped on a payables ageing crossing 180 days — the GSTR-3B reversal is not triggered because the payables ageing report is run monthly on quarter-end cut-off dates and misses the 180-day boundary between cycles; a daily-age tracker with the tax-period trigger fires the reversal in the correct GSTR-3B tax period.
- Government-body exception mis-applied on a state-transport-undertaking sale — the customer-master tag is not flipped from suppressed-206C(1H) to active-206C(1H) on state-body sales, and the Tier-1’s 206C(1H) collection obligation on the state-body sale is skipped, creating a Section 206C non-collection exposure with penalty implications.
- Warranty provision drawdown mis-booked against a FOMP debit for a different OEM — the provision ledger is not segregated by OEM and the drawdown on a Maruti FOMP claim closure is netted against the Hyundai provision balance, corrupting the per-OEM run-rate history and destabilising the next quarter’s provision refresh.
- Section 40(a)(ia) disallowance not identified on a non-deducted invoice — a Tier-2 invoice on which the Tier-1 failed to deduct Section 194Q is booked as a full-value expense in the P&L, and the 30% disallowance under Section 40(a)(ia) is missed in the income-tax return computation, creating a return-filing exposure that surfaces at the next scrutiny cycle.
How a reconciliation platform handles this
An audit-defensible Tier-1 auto component supplier reconciliation platform holds a vendor master tagged with PAN, preceding-FY turnover declaration and 194Q-applicability flag at onboarding, a customer master tagged with 194Q-deductor status (typically ON for every private-OEM customer, OFF for state-body customers under the Section 194Q(3)(a) exemption), and an invoice-generator with conditional 206C(1H) collection logic driven off the customer-master tag and CBDT Circular 13 of 2021 precedence rule. Section 393 payment-code mapping under the Income-tax Act 2025 successor regime (194Q → code 1090) carries through to Form 168 quarterly return generation. An Ind AS 37 provision model runs at part-family and OEM granularity with historical FOMP run rate as the reliable-estimate base, refreshed quarterly against actual claim closure, discounted to present value at the RBI G-Sec zero-coupon rate for the beyond-12-month leg where material, split into current and non-current per Schedule III Division II at each reporting date. A Rule 37 ITC reversal engine runs a per-invoice payables age tracker daily, fires the 180-day trigger the first day of the following tax period, populates the GSTR-3B reversal line with interest under Section 50, cross-tags to the specific OEM receivables ageing that produced the delay, and re-credits on subsequent payment. Monthly close produces a per-vendor 194Q ledger with FY-to-date base and deduction, a per-OEM receivables-side own-account credit ledger matched to Form 26AS, an Ind AS 37 warranty provision roll-forward with discount unwind, and a Rule 37 reversal register — the same four-stream evidence chain the statutory auditor traces through the year-end audit. Full posture at TDS reconciliation software India.
For Tier-1 suppliers running this at scale — where a mid-sized ₹1,240 crore Tier-1 carries 218 Tier-2 vendor PANs against four active OEM accounts, and a large ₹8,000 crore Tier-1 across multiple plants may carry 2,500-plus Tier-2 PANs against eight OEM accounts — the difference between manual month-end reconciliation discipline and platform-enforced statute compliance is the difference between reactive year-end Section 201, Section 271C, GST assessment and Ind AS 37 disclosure penalty exposure and proactive audit readiness across all four statute streams simultaneously.

- ▸ Section 194Q, Income-tax Act 1961 — Any person, being a buyer, who is responsible for paying any sum to any resident (called the seller) for purchase of any goods of the value or aggregate of such value exceeding fifty lakh rupees in any previous year, shall at the time of credit of such sum to the account of the seller or at the time of payment thereof, whichever is earlier, deduct an amount equal to 0.1% of such sum exceeding fifty lakh rupees as income-tax. Applies to buyers whose total sales, gross receipts or turnover from the business carried on by the buyer exceed ten crore rupees during the financial year immediately preceding the financial year in which the purchase is carried out. Effective 1 July 2021 per the Finance Act 2021.
- ▸ Section 194Q(3), Income-tax Act 1961 — The provisions of this section shall not apply to a transaction on which tax is deductible under any of the provisions of this Act, and tax is collectible under the provisions of section 206C other than a transaction to which sub-section (1H) of section 206C applies. Section 194Q(3)(a) further exempts payments made to the Central Government, State Government, an embassy, a High Commission, legation, commission, consulate, the trade representation of a foreign State, a local authority, or any other person notified by the Central Government from the ambit of buyer-side TDS.
- ▸ Section 206C(1H), Income-tax Act 1961 — Every person, being a seller, who receives any amount as consideration for sale of any goods of the value or aggregate of such value exceeding fifty lakh rupees in any previous year, other than the goods being exported out of India or covered under sub-section (1) or (1F) or (1G), shall at the time of receipt of such amount collect from the buyer a sum equal to 0.1% of the sale consideration exceeding fifty lakh rupees. Applies to sellers whose total sales, gross receipts or turnover from the business carried on exceed ten crore rupees during the financial year immediately preceding the financial year of collection.
- ▸ CBDT Circular 13 of 2021 dated 30 June 2021 — Guidelines under Section 194Q of the Income-tax Act 1961. Paragraph 4.9.4 clarifies that if a transaction is both within the purview of Section 194Q and Section 206C(1H), tax is required to be deducted under Section 194Q. Once the buyer deducts under Section 194Q, the seller is not required to collect tax under Section 206C(1H) on the same transaction. This buyer-precedence rule resolves the potential double-tax exposure at the OEM-to-Tier-1 interface where both parties independently cross the ₹10 crore turnover eligibility.
- ▸ Ind AS 37 — Provisions, Contingent Liabilities and Contingent Assets — Paragraph 14 — a provision shall be recognised when (a) an entity has a present obligation (legal or constructive) as a result of a past event; (b) it is probable that an outflow of resources embodying economic benefits will be required to settle the obligation; and (c) a reliable estimate can be made of the amount of the obligation. Paragraph 45 — where the effect of the time value of money is material, the amount of a provision shall be the present value of the expenditures expected to be required to settle the obligation, discounted using a pre-tax rate that reflects current market assessments of the time value of money and the risks specific to the liability. For an Indian entity the Reserve Bank of India–published G-Sec zero-coupon yield curve at the reporting date is the market-observable proxy for the risk-free discount rate.
- ▸ Section 393(1) Sl. 88, Income-tax Act 2025 (payment code 1090) — Payment code 1090 — purchase of goods (Section 194Q successor). The Income-tax Act 2025 carries forward the 0.1% rate, the ₹50 lakh aggregate FY per-PAN threshold, the ₹10 crore preceding-FY buyer-turnover eligibility, and the mutual-exclusion with Section 206C(1H) unchanged. The return migrates from Form 26Q under the legacy Act to Form 168 under the new Act, and the challan retains the Section 393 code lineage for reconciliation continuity across the cross-era boundary.
- ▸ Rule 37, CGST Rules 2017 — A registered person who has availed input tax credit on any inward supply of goods or services or both, but fails to pay to the supplier thereof, the amount towards the value of such supply along with the tax payable thereon, within the time limit specified in the second proviso to sub-section (2) of section 16, shall pay an amount equal to the input tax credit availed in respect of such supply along with interest payable thereon under section 50 while furnishing the return in FORM GSTR-3B for the tax period immediately following the period of one hundred and eighty days from the date of the issue of the invoice.
