India’s passenger vehicle market has handed policymakers an encouraging data point just weeks before the Union Budget – a 27% surge in car dispatches in December, the strongest monthly growth recorded in 2025.
According to data released by the Society of Indian Automobile Manufacturers (SIAM) on Tuesday, carmakers dispatched 399,216 passenger vehicles to dealers in December, pushing October–December volumes to a record 1.28 million units.
The jump, triggered by GST cuts announced in September, has sharpened the debate on whether the government should press further on automobile tax rationalisation in Budget 2026, or treat the rebound as a one-off, festival-led spike.
A tax experiment that worked—at least for now
The December surge follows the government’s decision to lower the GST burden on vehicles across segments. Taxes on SUVs with engine capacities above 1,500cc were reduced to 40% from 50%, while small cars saw levies cut to 18% from 28%.
The response was immediate. For the full calendar year 2025, passenger vehicle sales rose about 5%, accelerating from 4.2% growth in 2024. More significantly, the December print blew past industry expectations at a time when manufacturers had been guiding for flat demand.
Brokerages have since revised their outlook. Nomura and Elara Capital now expect passenger vehicle dispatches to grow around 8% in FY26, a sharp upgrade from the 1–2% growth that carmakers themselves were projecting at the start of the fiscal year.
Budget math: revenue risk or demand lever?
Automobiles are among the most heavily taxed consumer goods, contributing significantly to GST collections. Any further tax relief risks short-term revenue loss. But the December surge strengthens the argument that tax cuts can expand volumes fast enough to partly offset lower rates, a claim the auto industry has long made but rarely been able to prove with clean data.
ICRA said GST rationalisation introduced in September, along with a favourable monsoon, lifted vehicle sales sharply in the third quarter of FY26. The agency expects the Budget to focus on infrastructure spending, rural output and employment, while also addressing vehicle scrappage, localisation of components and alternative fuel ecosystems.
Why this data matters
Budget 2026 will be the first full-year fiscal plan after a period of weak consumption and uneven private investment. Policymakers are keen to explore getting a clearer understanding of how the demand-side measures can help revive growth without blowing up the fiscal math.
Auto demand, because of its deep linkages with manufacturing, steel, electronics and MSMEs, offers an attractive transmission channel. SIAM is confident and expects the positive momentum to continue well into 2026, even as it remains watchful of geopolitical risks and input cost volatility. If January and February sales hold up, it will strengthen the case for the government to view tax relief not as a concession, but as a growth tool.
Furthermore, carmakers have said they expect growth momentum to sustain in the final quarter of the fiscal year, led by interest in newly launched models.
