GST for automotive and auto components

Rate bands by specification, components by use, and dealer transitions that go wrong every time the rate changes.

The short answer

Automotive exposure concentrates in the specification driven rate entries for vehicles including the demerit band, the classification of components on the sole or principal use test after Westinghouse Saxby, free of cost tooling and its amortisation, dealer level discounts and incentives, demonstration vehicle credit and disposal under Section 18(6), and the Section 14 transition on every rate change with stock in the pipeline.

Vehicles and dealers

The entries turn on specification — engine capacity, length, fuel type and category — so the variant master is a tax document and every variant near a threshold needs specification evidence.

Rate changes are acute in this sector because of dealer stock, advances and the gap between invoicing and delivery. Section 14 must be applied transaction by transaction with recorded dates.

Manufacturer incentives, dealer margins and discount schemes must be treated consistently by both sides. Inconsistency produces demands on both.

Demonstration vehicles: credit subject to Section 17(5)(a) and its exceptions, and Section 18(6) with Rule 44 on disposal.

Exchange offers on trade in vehicles are non monetary consideration questions under Rule 27 and should be structured deliberately.

Components

Sole or principal use can place a dedicated component with the vehicle. The evidence is the drawing, the part number, the customer approval and the absence of an alternative market.

Aftermarket sales of the same part complicate the principal use analysis; a sales analysis by application is the answer.

Free of cost tooling and moulds supplied by the customer raise a Section 15(2)(b) valuation question that turns on who was contractually obliged to provide them.

Job work movements between tiers require Section 143 discipline, and the one year return period is the exposure.

Warranty and spares follow Circular 195/07/2023-GST, and extended warranties sold separately are separate supplies.

The controls

A variant level rate master with specification evidence at every threshold.

A classification file per part number with drawings, approvals and an application analysis.

A Section 14 transition protocol for dealers, adopted before the next rate change.

Written alignment with customers and dealers on discounts, incentives and tooling treatment.

What to do on Monday

  1. Maintain a variant rate master with threshold specification evidence.

  2. Build a per part number classification file with an application analysis.

  3. Adopt a dealer Section 14 transition protocol before the next rate change.

  4. Align discount, incentive and tooling treatment with counterparties in writing.

Questions we are asked on this

Which vehicles fall in the demerit band?

Those covered by the specified entries following the 2025 rationalisation. Verify against the variant specification and the period.

Can all components be classified as vehicle parts?

Only where the sole or principal use test is satisfied on evidence, and the department will apply the same test where the parts rate is higher.

Is credit available on demonstration vehicles?

Subject to Section 17(5)(a) and its exceptions where capitalised and used in the business; Section 18(6) applies on disposal.

Is customer tooling includible in our price?

It turns on who was contractually liable to provide it. State the obligation expressly.

How do we handle a rate change with pipeline stock?

Apply Section 14 transaction by transaction with recorded completion, invoice and payment dates.
