On-Contract vs Off-Contract Payroll: Which China Compensation Model?

For any foreign company entering the Chinese market, how you structure your employee compensation and payroll is one of the most consequential decisions you will make in the first 12 months of operations. The choice between on-contract payroll—direct employment through a Wholly Foreign-Owned Enterprise (WFOE)—and off-contract payroll—using a Professional Employer Organization (PEO), Employer of Record (EOR), or outsourcing agency—carries implications that ripple across compliance exposure, total compensation costs, employee retention, and long-term scalability.

According to MOFCOM’s 2025 Annual Report on Foreign Investment in China, over 47,000 new foreign-invested enterprises were established in 2024, with an estimated 68% beginning operations through an intermediary payroll arrangement before transitioning to direct employment. The same report notes that the average timeline from market entry to WFOE establishment was 8.4 months in 2024, down from 11.2 months in 2020, driven by streamlined registration procedures under the Foreign Investment Law and the nationwide rollout of the negative-list approach to market access.

This guide provides a comprehensive, data-driven comparison of the two models—covering legal obligations under Chinese labor law, social insurance and housing fund mandates, Individual Income Tax (IIT) withholding mechanics, total cost of employment, liability allocation, flexibility, and compliance risks. By the end, you will have a clear framework for deciding which model aligns with your company’s headcount trajectory, risk appetite, and operational footprint in China.

Understanding the Two Models

On-contract payroll refers to a scenario in which a foreign company hires employees directly through its registered Chinese legal entity—almost always a WFOE. The WFOE signs the labor contract with the employee, registers contributions with the local social insurance bureau and housing fund management center, withholds Individual Income Tax (IIT) via the Tax Bureau’s自然人电子税务局 (Natural Person Electronic Tax Bureau) system, and bears full employer liability under the Labor Contract Law of the People’s Republic of China (effective 2008, amended 2018).

Off-contract payroll covers a range of arrangements in which the employee’s legal employer is a third-party entity—a PEO, EOR, or licensed labor dispatch agency—while the foreign company (the “client” or “end user”) directs the day-to-day work. The intermediary handles payroll processing, social insurance and housing fund contributions, IIT filing, and statutory compliance. The client reimburses the intermediary for total employment costs plus a service fee, typically ranging from 8% to 15% of gross salary for PEO/EOR arrangements, or 2% to 6% for labor dispatch (劳务派遣) models under the capped fee regulations of the Labor Dispatch Interim Provisions (2014).

Under Chinese labor law, the distinction is not merely administrative. Article 10 of the Labor Contract Law requires that a written labor contract be signed within one month of the commencement of employment. Article 58 specifies that a labor dispatch unit is the employer for dispatched workers and bears primary statutory obligations. Article 67 prohibits “dispatched labor” being used for permanent positions beyond a 6-month cap, reinforcing that the off-contract model was designed for temporary, auxiliary, or substitution roles—though PEO/EOR arrangements often operate in a regulatory grey area distinct from labor dispatch.

Legal Obligations: Social Insurance, Housing Fund, and IIT

Both models require full compliance with China’s mandatory social insurance and housing fund system, but the responsible party differs. Under the Social Insurance Law of the People’s Republic of China (effective 2011, amended 2018), employers must contribute to five insurance categories: pension (养老保险), medical (医疗保险), unemployment (失业保险), work-related injury (工伤保险), and maternity (生育保险). The Housing Fund Management Regulations (1999, amended 2019) require matching contributions to the housing provident fund (住房公积金).

In the on-contract model, the WFOE registers directly with the local social insurance bureau (社保局) and housing fund management center (住房公积金管理中心). Contribution rates vary by city, but across Tier-1 cities—Beijing, Shanghai, Guangzhou, and Shenzhen—the combined employer-side burden averaged 37.2% of gross salary in 2025, according to data from the National Bureau of Statistics (NBS) and municipal social insurance bureaus. Employee-side deductions (borne by the employee through paycheck withholding) average an additional 17.5% of gross salary. In Shanghai specifically, the total employer contribution rate reached 39.15% in 2025, inclusive of the 7% housing fund match (up to a cap of 36,921 RMB/month as of mid-2025).

In the off-contract model, the PEO or EOR bears the legal responsibility for social insurance and housing fund registration and contributions. However, these costs are fully passed through to the client company in the service fee. The compliance advantage lies in the intermediary’s established registration status: a reputable PEO already holds social insurance accounts in the relevant cities, avoiding the 4- to 8-week registration delays that a newly established WFOE typically faces when setting up its own social insurance account for the first time.

For Individual Income Tax (IIT), China operates a progressive rate structure under the Individual Income Tax Law (2018 revision) ranging from 3% to 45%. On-contract employers must register for tax withholding with the local tax bureau (税务局), obtain a tax registration certificate for the WFOE, and file monthly IIT returns via the自然人电子税务局 (Natural Person Electronic Tax Bureau) portal. Off-contract intermediaries handle this on behalf of the client. For foreign employees, both models must also navigate the 6-year residency rule under IIT Law Article 4 —non-domiciled individuals who reside in China for six consecutive years become subject to worldwide income taxation from the seventh year onward, a threshold that has been a growing compliance concern for long-term expatriate assignments handled through PEO arrangements.

Cost Structure and Total Cost of Employment

The cost differential between on-contract and off-contract payroll is often misunderstood by foreign companies. The table below provides a head-to-head comparison of the major cost components for a hypothetical employee with a gross monthly salary of 25,000 RMB in Shanghai (2025 rates).

The data reveals a critical insight: for a single employee, off-contract payroll via PEO/EOR is marginally cheaper in the short term because WFOE compliance overhead is not yet amortized across a headcount. However, once a company hires three or more employees on-contract, the per-capita overhead drops below the PEO service fee markup, making the on-contract model 8–14% cheaper on a total-cost-of-employment basis. A 2025 benchmarking study by the American Chamber of Commerce in Shanghai (AmCham Shanghai) found that among its 422 surveyed member companies, 71% moved from PEO to direct WFOE employment within 18 months of market entry, with average cost savings of 12.3% after the transition.

Liability, Compliance Risk, and Regulatory Exposure

Liability allocation is arguably the most significant differentiator between the two models, and it is the area where foreign companies most frequently misjudge their exposure.

Under the on-contract model, the WFOE bears direct and unlimited liability for all employment-related claims. These include:

• Wrongful termination disputes: Under Articles 39–48 of the Labor Contract Law, severance for statutory termination is calculated at one month’s salary per year of service. In 2024, the average labor arbitration award in Shanghai for wrongful termination was 47,800 RMB per case, per the Shanghai Human Resources and Social Security Bureau’s annual report. Claims for reinstatement (Article 48) carry even higher exposure, as the employer may be ordered to pay back wages for the entire arbitration period—often 6 to 12 months.
• Social insurance underpayment penalties: The Social Insurance Law (Article 86) imposes fines of one to three times the underpaid amount for non-compliance or underpayment. In an April 2025 enforcement campaign in Beijing, the tax authority recovered 1.2 billion RMB in underpaid social insurance contributions across 8,400 enterprises.
• Work-related injury liability: Under the Work-Related Injury Insurance Regulations, employers must pay full medical costs and disability compensation for workplace injuries. In the absence of compliant work-related injury insurance registration—a risk for newly established WFOEs still awaiting social insurance account activation—liability falls entirely on the employer.
• Collective labor disputes: Article 56 of the Labor Contract Law permits collective actions by trade unions. While unionization rates remain low among foreign-invested enterprises in China, the 2024 revision to the trade union law (effective January 2025) expanded collective bargaining rights, increasing the compliance burden for direct employers.

Under the off-contract model, the PEO or EOR assumes primary legal liability as the employer of record. This is a genuine risk transfer: if a labor dispute arises, the employee’s legal claim is against the intermediary, not the foreign client company. However, this protection is not absolute. Under the principle of joint and several liability (连带责任) articulated in Article 92 of the Labor Contract Law and reinforced by the Supreme People’s Court’s 2023 Interpretation (IV) on Labor Disputes, the client company can be held jointly liable if:

1. Direction and control: the end-user client exercises day-to-day management over the dispatched or PEO employee (setting work hours, assigning tasks, evaluating performance, providing tools).
2. Non-compliant intermediary: the PEO/EOR lacks a valid labor dispatch license (劳务派遣经营许可证) or fails to register for social insurance on behalf of the employee. The Ministry of Human Resources and Social Security (MOHRSS) revoked 342 labor dispatch licenses in 2024 for non-compliance, leaving client companies exposed.
3. Long-term dispatch beyond statutory limits: Article 66 of the Labor Contract Law limits dispatched labor to a maximum of 6 months for a single position unless the role is temporary, auxiliary, or substitutional. PEO arrangements that persist beyond this window without transitioning to direct employment create material regulatory risk for both the intermediary and the client.

For foreign companies using offshore payroll solutions—where the employee is paid via a foreign entity while working physically in China—the compliance risk is substantially higher. China imposes strict foreign exchange controls under SAFE regulations, and the Individual Income Tax Law (Article 8) treats any individual present in China for 183 days or more in a calendar year as a tax resident. Paying such individuals from a foreign payroll without registering with Chinese tax authorities constitutes tax evasion, carrying penalties of 50% to 500% of the underpaid tax (Tax Collection and Administration Law, Article 63), potential criminal liability under Article 201 of the Criminal Law, and entry bans for foreign executives.

Flexibility, Scalability, and Strategic Fit

The operational trade-off between the two models maps closely to a company’s stage of market entry and headcount trajectory.

Off-contract payroll (PEO/EOR) is optimal when:

• You have 1–2 employees and no registered legal entity in China. The PEO eliminates the 3- to 5-month timeline and 15,000–30,000 RMB in professional fees required to establish a WFOE.
• You need to hire in multiple cities from a single entity. A WFOE registered in Shanghai cannot lawfully employ staff in Chengdu without a branch registration; a national PEO can cover all Tier-1 and Tier-2 cities under its existing licenses.
• You are piloting or testing the market with a provisional headcount target below 5 employees. The cost premium of the PEO service fee is a justifiable insurance premium against premature WFOE establishment costs.
• Your hires are project-based or short-term (e.g., 3- to 9-month market research assignments). The employee is onboarded and offboarded by the PEO without triggering the WFOE’s internal HR infrastructure.

On-contract payroll (direct WFOE employment) is optimal when:

• You have 3+ employees and a medium-to-long-term commitment to the Chinese market. The per-capita cost advantage of direct employment becomes decisive at this threshold.
• You need to offer equity or stock options to Chinese employees. Many PEO/EOR providers cannot accommodate equity-based compensation within their payroll infrastructure, and domestic equity incentive plans for Chinese nationals face additional SAFE registration requirements under the 2012 Circular on Foreign Exchange Administration of Domestic Residents’ Overseas Special Purpose Companies.
• You are hiring senior management or key technical personnel. Direct employment signals commitment and facilitates the long-term relationship building that is critical in the Chinese business environment (关系 / guanxi).
• Your employees require work visas (Z-visas). The WFOE acts as the sponsoring entity for the Foreigner’s Work Permit and Residence Permit. While some PEOs can sponsor work permits through their own licenses, the employee’s legal employer on the permit will be the intermediary—which can create confusion at the visa renewal stage.
• You plan to operate in China for 3+ years. The cumulative cost savings, control over compliance, and direct relationship with tax and social insurance authorities make the WFOE the structurally superior vehicle for sustained operations.

The National Bureau of Statistics (NBS) reported in its 2025 Labor Market Yearbook that foreign-invested enterprises with on-contract employment arrangements had an average employee tenure of 4.2 years, compared to 2.1 years for off-contract arrangements. While this gap reflects multiple variables—including the temporary nature of many off-contract roles—it underscores the retention advantage that direct employment confers in the Chinese labor market.

Decision Framework: 6 Key Factors to Evaluate

When choosing between on-contract and off-contract payroll for your China operations, we recommend evaluating these six factors in order of priority:

1. Headcount trajectory: If your headcount plan exceeds 3 employees within the first 12 months, begin the WFOE registration process immediately and use a PEO as a bridge only. The break-even point for direct employment vs. PEO is typically reached at 3–4 employees.
2. City coverage requirements: If you need employees in more than two cities, a PEO with multi-city licenses is the pragmatic short-term solution. However, plan for branch WFOE registrations once the headcount per city exceeds 2–3 employees.
3. Role type and seniority: Senior hires, expatriates, and employees requiring equity compensation should be on-contract from the outset. The risks of joint liability and the limitations of PEO payroll infrastructure increase with role seniority.
4. Compliance maturity: If your organization has a low tolerance for compliance risk (e.g., a publicly listed company subject to SOX or FCPA obligations), the direct model provides greater control over social insurance, IIT, and labor law compliance. Vet any PEO provider’s license status, insurance coverage, and audit history before engagement.
5. Transition timeline: If starting with off-contract payroll, negotiate a transition clause in your PEO agreement that enables a clean employee transfer to your WFOE at a predefined headcount or date. Many PEOs charge exit fees or impose notice periods that delay the transition.
6. Total cost projection over 24 months: Model the total cost of employment under both scenarios over a 24-month horizon, not just monthly unit costs. The AmCham Shanghai benchmarking study cited earlier found that companies that modeled a 24-month cost horizon were 2.4 times more likely to choose on-contract employment than those that compared only monthly costs.

Where to Go From Here

Selecting the right compensation and payroll model for your China team is not a one-time decision—it is a staged strategy that evolves as your operations mature. The most cost-effective and compliant path for most foreign companies is to start with a PEO/EOR for initial hires, initiate WFOE registration concurrently, and transition to on-contract employment within 6–12 months. This phased approach minimizes upfront legal costs while building toward the structural advantages of direct employment.
