China to Reinstate Battery Tax, Exempts Next-Gen Tech

China will reinstate a consumption tax on mature battery technologies including lithium-ion batteries, while exempting next-generation alternatives such as solid-state and sodium-ion batteries through the end of 2028, marking a strategic pivot in the world’s largest EV market. The phased policy, announced jointly on July 17 by the Ministry of Finance, General Administration of Customs, and State Taxation Administration, represents Beijing’s latest step toward “oil-electricity equalization” (油电同权) — a broader effort to equalize tax treatment between conventional fuel vehicles and new energy vehicles.

Policy Details

Effective September 1, 2026, a 2% consumption tax will apply to mercury-free primary batteries, nickel-metal hydride (NiMH) batteries, lithium primary batteries, lithium-ion batteries, and vanadium redox flow batteries. The rate will rise to the standard 4% on September 1, 2027, as Caixin Global reported. Photovoltaic cells will follow a separate timeline, with a 2% tax beginning April 1, 2027, rising to 4% on April 1, 2028.

At the same time, emerging technologies will enjoy a temporary reprieve. From September 1, 2026 through December 31, 2028, sodium-ion batteries, solid-state batteries, fuel cells, and next-generation photovoltaic technologies — including perovskite, tandem, and gallium arsenide cells — will remain exempt from consumption tax. Products eligible for preferential treatment must comply with national standards and obtain certification from CMA-accredited testing institutions.

Historical Context

China first imposed a 4% consumption tax on batteries in February 2015, but exempted seven categories including lithium-ion batteries, solar cells, and fuel cells. The exemption was designed to nurture a domestic battery industry that was then in its infancy. Over the past decade, that strategy has succeeded beyond expectations: China is now the world’s largest producer and consumer of lithium-ion batteries, with EV penetration exceeding 60%, as Xinhua News Agency noted.

However, the industry now faces significant oversupply and intense price competition, with lithium battery cell prices falling to approximately 0.35-0.4 yuan/Wh. The tax reinstatement signals that Beijing believes the lithium battery sector no longer needs broad-based government support.

Expert Analysis

Professor Gao Lin of Jiangxi University of Finance and Economics told Yicai/First Financial that the differentiated policy serves dual purposes: “On one hand, it promotes fair tax burden sharing in the electric vehicle industry; on the other hand, it continues to leverage the industrial guidance effect of tax policy.” Gao noted that for frontier technologies like sodium-ion and solid-state batteries that have not yet achieved large-scale mass production, the tax exemption window reflects continued policy support for cutting-edge industries.

An anonymous securities analyst quoted by Yicai assessed the direct cost impact as minimal. Lithium battery cell prices of approximately 0.35-0.4 yuan/Wh mean a 2% consumption tax adds only about 0.007-0.008 yuan/Wh — far smaller than the cost fluctuations caused by lithium carbonate price swings in recent years. For consumers, the impact translates to several hundred yuan per vehicle.

The Broader “Oil-Electricity Equalization” Agenda

The battery tax reinstatement is the latest in a series of policy changes phasing out preferential tax treatment for new energy vehicles. As ChinaEVHome reported, earlier this month authorities announced that vehicle and vessel tax exemptions for NEVs will be canceled effective January 1, 2027. Since January 2026, NEV purchase tax has already been reduced from full exemption to a 50% reduction, capped at 15,000 yuan per vehicle.

Cui Dongshu, Secretary-General of the China Passenger Car Association (CPCA), told Yicai that “this policy adjustment means the curtain has officially been drawn on ‘oil-electricity equalization.’ From the halving of purchase tax, to the cancellation of vehicle and vessel tax exemptions, to the restoration of battery consumption tax, the tax preference ‘protection period’ for new energy vehicles is being phased out in stages and with rhythm.”

Implications for Next-Generation Battery Technologies

The exemption window running through 2028 creates both opportunity and urgency for companies racing to commercialize next-generation battery chemistries. Solid-state batteries, which promise higher energy density and improved safety, remain at an early stage — CATL Chairman Zeng Yuqun stated in June 2026 that the technology is at maturity level 4 on a 1-9 scale, with level 9 required for mass production. Sodium-ion batteries, offering lower cost and abundant raw materials at the expense of energy density, are closer to commercialization but still face scaling challenges.

What to Watch

As China’s domestic consumption tax revenue reached 1.69 trillion yuan in 2025 — making it the third-largest tax category — the government faces growing fiscal pressures that are accelerating the phaseout of long-standing tax preferences. Key questions remain: Will major manufacturers like CATL and BYD accelerate their next-gen battery investments? How will the tax impact China’s international competitiveness in battery exports? And what further “oil-electricity equalization” measures — such as road maintenance fees for EVs or fuel tax reform — might follow?

For now, the message from Beijing is clear: China’s battery industry has matured, and the era of blanket tax exemptions is giving way to a more targeted approach designed to steer innovation toward the technologies of tomorrow.
