China's fuel vehicle sales plunged 37.5% year-on-year in May 2026 to just 650,000 units, with their share of new car sales falling to 43.1%. The rapid decline in ICE vehicles has triggered a chain reaction including road maintenance funding gaps, forcing a comprehensive overhaul of the auto tax system.
ICE Cliff: The Structural Signal Behind the Data
In May 2026, China's fuel vehicle sales plunged 37.5% year-on-year to just 650,000 units, with their share of new car sales falling to 43.1%. In the passenger vehicle segment, ICE penetration has dropped below 40%. This decline far exceeds previous expectations — vehicle trade-in subsidies drove growth in 2024 and 2025, but after partial reductions in 2026, domestic demand fell accordingly. Notably, the Middle East situation pushed international oil prices higher, further suppressing fuel vehicle performance.
The cliff-like decline in fuel vehicle sales directly impacts the existing tax system built on fuel consumption. Domestic non-toll highway maintenance funds primarily come from fuel consumption taxes — currently 1.52 yuan per liter for gasoline and 1.2 yuan per liter for diesel. Pure electric vehicles consume no fuel, while PHEVs and EREVs consume very little.
Tax System Faces Comprehensive Overhaul
Vehicle consumption taxes and vessel taxes are also primarily designed around fuel vehicles, with passenger vehicle tax rates almost entirely tied to engine displacement. As NEV share grows, tax system adjustments are urgent:
- Purchase taxes have shifted from exemption to half-rate collection (5% for 2026-2027, with a 15,000 yuan reduction cap)
- Battery export rebates already reduced to 6% from April 2026 and complete cancellation scheduled for 2027
- Industry proposals include: decoupling vessel taxes from engine displacement and linking them to vehicle weight or dimensions; exploring "mileage-based taxes" as an alternative
Current Tax Structure and Trends
| Tax Category | Current Standard | ICE Impact | NEV Impact | Trend |
|---|---|---|---|---|
| Fuel Consumption Tax | Gasoline 1.52 yuan/L, Diesel 1.2 yuan/L | Directly bears | Nearly exempt | Rapidly shrinking |
| Vehicle Purchase Tax | ICE 10%, NEV 5% (2026-2027) | Normal payment | Half-rate | Expires end of 2027 |
| Vessel Tax | Tied to displacement, BEV exempt | Bound to displacement | Exempt | Under reform |
| Battery Export Rebate | Reduced from 13% to 6%, canceled 2027 | N/A | Phasing out | Complete cancellation |
Policy Response and Overseas Implications
On June 23, 2026, three ministries issued support policies: cultivating the auto aftermarket; reforming auto circulation in 40 pilot cities; enabling same-day purchase and registration. The core logic is that with new vehicle sales growth slowing, activating aftermarket consumption (used car trading, auto finance, after-sales, modifications) can stabilize overall industry scale.
EX1000.COM analysis indicates that tax system restructuring will accelerate China's auto market transition from "policy-driven" to "market-driven" growth. By 2027, NEVs will compete with fuel vehicles on a level playing field and must be sufficiently competitive in total cost of ownership. This is beneficial for long-term healthy industry development, though it may cause short-term market fluctuations.
