The 11-Year Tax Exemption Ends, Lithium-ion Batteries Now Subject to Consumption Tax: Not Bad News, But a Watershed Moment for Industry Reshuffling

From February 2015 to August 2026, lithium-ion batteries enjoyed over 11 years of consumption tax exemption. According to the latest tax announcement, starting September 1, 2026, lithium-ion batteries will be subject to a 2% consumption tax, reverting to the 4% benchmark tax rate on September 1, 2027. The tax exemption policy for sodium-ion batteries, solid-state batteries, and fuel cells will continue until December 31, 2028.

This news has sparked widespread market concerns about price increases by automakers and soaring energy storage costs. However, setting aside short-term sentiment, this tax adjustment is not simply a matter of "increasing taxes," but rather a crucial turning point for the domestic lithium battery industry, moving from policy support to mature market competition, and marking the beginning of a high-quality industry reshuffling.

The 11-year tax exemption policy was originally intended as a phased measure for industry development. Ten years ago, China's lithium battery industry chain was weak, technology was immature, and production capacity was limited. The core purpose of the consumption tax exemption was to reduce production costs for enterprises, rapidly support the development of the power battery and energy storage lithium battery sectors, and build a complete domestic industry chain.

After more than a decade of development, my country's lithium battery production capacity, shipments, and global market share have firmly established itself as the world's largest. The penetration rate of new energy vehicles has exceeded 60%, and industrial, commercial, and residential energy storage are widely available. The upstream and downstream of the industry chain are well-developed, and China has long possessed the ability to compete independently in the market. The historical mission of the universal tax exemption has been completed, and the orderly withdrawal of the policy is a normal law of industrial development.

Many people overemphasize the tax burden, which stems from a lack of understanding of tax rules. This policy sets a two-year tiered buffer period, greatly reducing the short-term pressure on the industry. Based on current mainstream battery cell prices, a 2% consumption tax only increases the cost per watt-hour by a few cents. For a 60kWh residential new energy vehicle, the additional cost at the battery cell level is less than 500 yuan. Even if the full 4% tax rate is reinstated after two years, the additional cost per vehicle will be less than 1,000 yuan.

Compared to the thousands or even tens of thousands of yuan in cost changes caused by fluctuations in lithium prices and raw material prices, the incremental cost of the consumption tax is almost negligible. More importantly, the consumption tax is levied only at the cell manufacturing stage; downstream PACK assembly and vehicle production stages can legally deduct the tax, eliminating the layered tax burden. This means end-user automakers and energy storage projects will not experience a surge in costs, and ordinary consumers will hardly feel any fluctuation in end-market prices.

The greatest value of this tax system is using differentiated taxation to facilitate industry consolidation and precisely guide industrial upgrading.

The reinstatement of taxation in mature lithium battery sectors directly squeezes low-end, competitive production capacity. Currently, many small and medium-sized cell manufacturers lack technological and scale advantages, relying on low prices and high volume for survival, with net profit margins generally only 3%-5%. With the full implementation of the consumption tax, the profit margins of these inefficient production capacities will be drastically compressed, accelerating their exit from the market.

Meanwhile, leading companies like CATL and BYD, with their large-scale production, integrated supply chain layout, and stable pricing power, can absorb most of the tax burden through process optimization and internal cost reduction. This will further increase industry concentration, end the low-end, disorderly price war, and force the industry to return to competition based on quality and technology.

At the same time, the policy continues to provide tax-free support for cutting-edge technologies such as sodium batteries and solid-state batteries, with a very clear direction: no longer subsidizing mature, fiercely competitive sectors, but fully supporting the industrialization breakthroughs of next-generation battery technologies. By reducing the R&D and mass production costs of new technologies through tax incentives, it guides capital and enterprises to move beyond low-end competition, focus on tackling cutting-edge technologies, and address future industry shortcomings.

This adjustment also officially completes the tax system puzzle of "equal treatment for oil and electricity" in the new energy industry. For many years, the new energy vehicle and lithium battery industries have risen rapidly relying on multiple tax incentives and subsidies, while gasoline vehicles and refined oil have always paid consumption tax in full, resulting in a long-term unfair tax competition environment.

With the gradual reduction of purchase tax and vehicle and vessel tax incentives for new energy vehicles, coupled with the implementation of the lithium battery consumption tax, the tax rules for new energy and gasoline vehicle sectors are now completely leveled. The complete withdrawal of policy incentives means that the industry has completely bid farewell to the era of "making money through policy incentives" and must rely on product strength, safety, and cost-effectiveness to establish itself in the market.

For the energy storage industry, this presents a significant opportunity for standardization and upgrading. Previously, the energy storage sector experienced rampant expansion, with many companies relying on inferior, low-priced cells to secure projects, creating safety hazards. With increased cost barriers, low-priced, inferior cells will gradually be phased out. Power station lifespan, safety and stability, and system reliability will replace low prices as the core standards for energy storage bidding, and the industry is officially shifting from "price competition" to "quality competition."

Ultimately, the 11-year tax exemption was nurturing, while the resumption of taxation signifies maturity. Tax adjustments are not intended to suppress the industry, but rather to force it to break free from policy dependence. In the future, the core competitiveness of lithium battery companies will no longer be policy dividends, but rather technological iteration, cost control, and product quality.

The lithium battery industry, now free from policy support, will experience short-term reshuffling and growing pains, but in the long term, it will completely move away from extensive development, giving rise to truly globally competitive domestic companies and propelling China's new energy industry into a new stage of high-quality development.
