China Corporate Income Tax (CIT): Rates & Rules (2025)

Accounting › Country Tax Guides › China Tax

China’s Corporate Income Tax (CIT), sometimes called Enterprise Income Tax, is the main tax on company profits. This guide explains the standard 25% rate, who is a resident versus non-resident enterprise, how taxable income is calculated, the quarterly prepayment and annual reconciliation system, and why most well-structured companies pay an effective rate below the headline figure.

How does China’s corporate income tax work?

China’s CIT applies a standard 25% rate to company profits — taxable income calculated as gross income minus deductible costs, allowable expenses, and losses carried forward from prior years. Unlike some countries, there are no provincial or local CIT add-ons, so the 25% is a clean national rate. CIT applies to companies in all sectors, but not to sole proprietorships and partnerships, whose profits are taxed as individual income.

The tax is settled annually but prepaid quarterly based on accounting records, with the final figure confirmed by a year-end audit and annual reconciliation. While 25% is the headline rate, a wide range of incentives — for high-tech firms, small businesses, and certain regions — can substantially reduce the effective rate. Understanding the CIT framework is essential for any company operating in China.

Who is a resident versus non-resident enterprise?

A resident enterprise is one incorporated in China, or a foreign company whose place of effective management is in China. Resident enterprises are taxed on their worldwide income at 25%. A non-resident enterprise is incorporated outside China without effective management there, and is taxed only on its China-source income — either through an establishment in China or via withholding tax on passive income.

This residence distinction determines the scope of what China taxes. A Chinese subsidiary of a foreign group is a resident enterprise taxed on worldwide profits, while a foreign company merely earning income from China faces tax only on that China-source income. Understanding whether an enterprise is resident or non-resident is the starting point for determining its CIT obligations and the rules that apply to it.

How is taxable income calculated?

CIT taxable income is gross income minus non-taxable income, tax-exempt income, deductible costs and expenses, and allowable losses carried forward from previous years. It’s calculated on an accrual basis — income recognized when earned and deductions when incurred. The result is effectively a tax on profit, with the 25% rate (or an applicable incentive rate) then applied to reach the CIT payable.

Deductions must generally be supported by fapiao — official Chinese tax invoices — which can challenge foreign companies unfamiliar with the system. Losses can be carried forward up to five years (ten for high-tech and certain enterprises) but not carried back. Accurately determining taxable income, with proper documentation of deductible expenses, is central to calculating CIT correctly and minimizing it legitimately.

How is CIT prepaid and reconciled?

CIT is prepaid monthly or quarterly based on the company’s accounting records, with returns and prepayments due within 15 days after the end of each period. The annual CIT reconciliation is then filed by May 31 of the following year, based on the company’s year-end audit, with any overpayment refunded or carried forward and any shortfall paid. This system spreads the tax across the year while finalizing it annually.

The annual reconciliation reconciles the quarterly prepayments with the actual annual liability, accounting for all income, deductions and incentives. For foreign-invested enterprises, a separate CIT audit report by a certified Chinese tax agent may be required in some regions. Meeting the quarterly prepayment and May 31 annual filing deadlines is a core compliance obligation, with penalties for late filing or payment.

A practical example: basic CIT calculation

Consider a company with RMB 10 million of gross income and RMB 7 million of deductible costs and expenses, giving taxable income of RMB 3 million. At the standard 25% rate, CIT would be RMB 750,000. But if the company qualifies as a Small Low-Profit Enterprise, the effective rate on that RMB 3 million could be just 5%, dramatically reducing the tax to around RMB 150,000.

The example shows both the basic CIT calculation and why incentives matter so much — the same profit can be taxed at 25% or at a fraction of that depending on the company’s status. Determining taxable income correctly, then applying any incentive the company qualifies for, is the essence of CIT planning. Understanding both the standard mechanics and the available incentives is key to managing corporate tax in China.

How does CIT compare to individual business taxation?

A key distinction in China is that CIT applies to companies, while sole proprietorships and partnerships are taxed under individual income tax at the business income rates of 5%-35%, not CIT. So an entrepreneur choosing between incorporating and operating as an individual business faces a choice between the 25% CIT (with incentives potentially much lower) and the progressive 5%-35% IIT business scale.

For profitable businesses, incorporation with access to SLPE or HNTE incentives can produce a lower effective rate than the individual business scale, while also providing liability protection. The decision parallels business structure choices elsewhere, weighing tax rates, compliance burden and liability. Understanding that CIT and individual business taxation are separate regimes is essential for entrepreneurs deciding how to structure their China operations.

Why the effective rate often differs from 25%

While 25% is the headline CIT rate, most well-structured companies pay less. Early-stage firms qualifying as SLPEs pay an effective 5% on the first RMB 3 million of profit; high-tech firms pay 15%; companies in certain zones pay 15%; and the R&D super-deduction further reduces taxable income for innovative businesses. The result is that the effective rate for many companies is materially below 25%.

This gap between the headline and effective rate is a defining feature of Chinese corporate tax. ‘China CIT is 25%’ is true but misleading for companies that qualify for incentives. Understanding the available concessions, and structuring to capture those a company qualifies for, is central to corporate tax planning in China — turning the standard rate into a much lower effective burden for eligible businesses.

How does CIT relate to other business taxes?

CIT is just one of several taxes a company pays in China. Alongside it, businesses charge and remit VAT on their sales (at 13%, 9% or 6%), pay urban maintenance and construction tax and education surcharges on top of VAT, withhold IIT from employee salaries, contribute to social insurance, and may face consumption tax, stamp duty and other levies. CIT is the tax on profit specifically.

Understanding how CIT fits within this broader tax landscape is important, because a company’s total tax burden combines CIT with VAT, surcharges, payroll-related taxes and others. Each has its own rules, rates and filing requirements. While this guide focuses on CIT, managing a company’s overall tax position requires coordinating all these taxes — explored across our other China tax guides covering VAT, indirect taxes and compliance.

Why understanding CIT matters for businesses

For any company operating in China — domestic or foreign-invested — understanding CIT is fundamental. It determines the tax on profits, drives the value of incentives that can dramatically cut the effective rate, dictates the quarterly and annual filing obligations, and requires the fapiao discipline that makes deductions claimable. Getting CIT right is central to both compliance and profitability.

Companies that understand the CIT framework can structure to capture incentives, document deductions properly, meet filing deadlines, and avoid the penalties and audit risk of non-compliance. With China’s increasingly digital, data-driven tax administration, accurate CIT management is more important than ever. Mastering the corporate income tax — its rate, calculation, incentives and compliance — is essential for any business to operate successfully and tax-efficiently in China.

Common CIT mistakes to avoid

Frequent CIT errors include missing the quarterly prepayment or May 31 annual reconciliation deadlines, failing to collect valid fapiao for deductions, confusing the headline 25% rate with the lower effective rate available through incentives, and not applying loss carryforwards correctly. Each can lead to penalties, disallowed deductions, or overpaying tax.

Avoiding them means meeting all filing deadlines, maintaining fapiao discipline, pursuing the incentives the company qualifies for, and tracking loss carryforwards. Because China’s tax administration is increasingly data-driven, accurate and timely compliance is essential. Understanding the CIT framework — its rate, calculation, incentives and deadlines — helps companies avoid these common pitfalls and manage their corporate tax both compliantly and efficiently.

How is CIT residence determined for foreign companies?

A foreign-incorporated company can still be a Chinese tax resident if its place of effective management is in China — meaning the substantial and overall management and control of its production, business, personnel, accounts and assets is exercised in China. Such a company is taxed on worldwide income at 25%, like a domestic firm. This rule prevents companies managed from China from escaping resident taxation through foreign incorporation.

For multinational groups, the effective management test means where a company is actually run matters as much as where it’s incorporated. A foreign holding company genuinely managed from China could be treated as a Chinese resident enterprise. Understanding the effective management concept is important for international structures, as it determines whether worldwide income falls within China’s CIT net, with significant consequences for the group’s overall tax.

How is CIT administered and filed?

CIT is administered by the State Taxation Administration through an increasingly digital system. Companies file CIT prepayment returns monthly or quarterly within 15 days of period-end, and the annual reconciliation return by May 31, based on audited accounts. The filing involves reporting income, deductions, incentives and any related-party transactions, with payment of any balance due or claim for refund.

The digital tax administration, integrated with the Golden Tax invoice system, cross-checks filings against invoices and other data. This makes accurate, consistent and timely filing essential. Companies often use accounting software and professional tax agents to manage CIT filing, especially given the audit and reconciliation requirements. Understanding the filing calendar and process is fundamental to CIT compliance, ensuring a company meets its obligations and avoids penalties for late or inaccurate returns.
