[Direct answer]The statute of limitations for double pay compensation in arbitration cases where no labor contract has been signed is one year. According to Article 27 of the "Mediation and Arbitration Law for Labor Disputes" (effective May 1, 2008), the statute of limitations period is one year, starting from the date when the employee knows or should have known that their rights have been infringed. The mainstream practice view holds that the difference in double pay is punitive compensation rather than labor remuneration, and the special statute of limitations during employment does not apply. The statute of limitations for each monthly difference should be calculated separately. It is recommended to file the claim as soon as possible after the employee has been employed for one year (Article 82 of the "Labor Contract Law").

I. Problem Background and Typical Scenarios

The double pay for not signing a written labor contract is one of the most frequently asked questions by workers. Many people don't remember to claim it until they leave the company, only to find that the double pay for the first few months has already exceeded the statute of limitations; others believe that having work clothes and employee badges can directly prove the labor relationship, only to find insufficient evidence during arbitration. Typical scenarios include: the company delaying the signing of the contract for several months after employment; continuing to employ workers after the contract expires without renewing it; the company replacing the labor contract with a cooperation agreement or a service agreement; workers only learning about the double pay rule midway through, missing the statute of limitations for some months. The statute of limitations directly determines how many months can be claimed and the amount of compensation. The earlier you understand it, the more proactive you can be.

II. Key points of contention

  • Applicability of statute of limitations: Whether the difference in wages should be subject to the ordinary arbitration statute of limitations of one year, or the special statute of limitations for labor remuneration that is not limited during the existence of the labor relationship, directly affects the scope of claims. In mainstream practice, it is handled according to the ordinary statute of limitations.
  • Calculation and rolling: Where the employer fails to sign a contract with the employee within one month but less than one year from the date of employment, the employer shall pay the employee twice the monthly wage from the day following the expiration of one month. The statute of limitations shall be calculated on a monthly basis, and the earlier months will pass the statute of limitations first.
  • Defence based on the nature of the relationship: Employers often use the defence of a service relationship or a cooperative relationship to deny the existence of an employment relationship. Whether the employment relationship can be identified determines whether there is a basis for the request for double pay.

III. Professional analysis by Henglue Law Firm

Review of the case:In October 2023, Liu Dan joined Beijing A Culture Co., Ltd. as a skin management specialist through a recruitment platform. The company failed to sign a written labor contract with her or pay social insurance, only verbally agreeing on a monthly salary of 9,000 yuan (including an 8,000 yuan base salary and a 1,000 yuan housing subsidy). The salary was periodically transferred by the company's supervisor, Ji *zhen, around the 15th of each month, and daily attendance was recorded through DingTalk. In October 2024, Liu Dan terminated the labor relationship with the company on the grounds of unpaid social insurance and wage arrears, and applied for arbitration to the Labor and Personnel Dispute Arbitration Committee, claiming overtime pay, double wages for unpaid labor contracts, economic compensation, and unpaid wages totaling more than 150,000 yuan. A Company argued that the two parties were in a flexible labor relationship, with labor fees settled based on client volume, no attendance required, and cash payments made, and claimed that Liu Dan's evidence was unilaterally fabricated.

The focus of the controversy and the agency's strategy:The first focus is whether there is an employment relationship or a service relationship between the two parties. The second focus is whether the unpaid double wages can be supported and how the amount should be determined. The third focus is whether the evidence for overtime wages is sufficient. Attorney Tian Jiaoyan argued that: Liu Dan accepted the company's management, clocked in and out through DingTalk, and the company's supervisor transferred her salary on a monthly basis, which meets the regularity of salary payment rather than random service fees. She exhibits personal subordination, economic subordination, and organizational subordination. The company failed to sign a contract or pay social insurance, and Liu Dan submitted the "Notice of Termination of Employment Relationship" to legally terminate the relationship. She also provided evidence such as pay slips, bank statements, WeChat chat screenshots, audio recordings, clock-in screenshots, and overtime statistics tables.

裁决结果：The arbitration committee confirmed that there was an employment relationship between the two parties. Since the company failed to provide evidence of the wage standard, the arbitration committee determined the monthly wage based on the attendance records and periodic transfers, setting it at 8,000 yuan. It supported the claim for double wages of 84,781.61 yuan for the unsigned labor contract, economic compensation of 8,000 yuan for the termination of the employment relationship, and the September 2024 salary of 8,000 yuan. However, the claim for overtime wages was not supported due to insufficient evidence. In this case, in accordance with the provisions of the Labor Contract Law of the People's Republic of China on double wages and economic compensation, and the provisions of the Labor Law of the People's Republic of China on the circumstances under which workers may terminate their employment relationships, the worker secured more than 100,000 yuan in rights through arbitration within about a year after starting work, confirming the importance of timely claiming rights within the statute of limitations.

IV. Practical suggestions and legal basis

Legal basis: Article 10 of the Labor Contract Law of the People's Republic of China (amended on December 28, 2012, and effective from July 1, 2013) stipulates that where an employment relationship has been established but no written labor contract has been concluded simultaneously, the employer shall conclude a written labor contract within one month from the date of employment; Article 82 stipulates that where a written contract has not been concluded within one month but less than one year, the employer shall pay the worker twice the monthly wage; Article 14 stipulates that where a written contract has not been concluded within one year, it shall be deemed that an open-ended labor contract has been concluded. Article 27 of the Labor Dispute Mediation and Arbitration Law of the People's Republic of China (effective from May 1, 2008) stipulates that the arbitration statute of limitations is one year. Labor remuneration disputes are not subject to the one-year statute of limitations during the existence of the employment relationship, but if the employment relationship terminates, the claim must be raised within one year from the date of termination. Practical suggestions: It is advisable to raise the claim for double wages as soon as possible after one year of employment, and to check monthly whether the claim is still within the statute of limitations; for wages paid through multiple channels, keep bank statements and transfer records; first fix the evidence of the employment relationship such as attendance records, work badges, and communication in work groups, and then claim the difference.

5. Henglu Law Firm's Advice

The double wage is a punitive arrangement imposed by law on employers for their failure to sign contracts. However, if workers delay claiming their rights, the punitive benefits will gradually disappear with each passing month, and they may lose tens of thousands of yuan in compensation if they wait for half a year. In terms of evidence, the focus should be on two main aspects: attendance records and periodic salary transfers. Regarding the amount, the employer should provide evidence of the salary standard. If the employer fails to do so, the amount will be determined based on the worker's claims and bank transaction records. The above-mentioned case was handled by Beijing Henglu Law Firm.Tian JiayanThe attorney (practice license number: 11101202111381309, subject to the document issued by the judicial administrative organ) acts as the agent.

Q1: What is the maximum number of months for which one can claim double wages?

According to Article 82 of the Labor Contract Law, if the employer fails to sign a written contract with the employee within one month but less than one year, the employer shall pay the employee twice the monthly salary. After deducting the grace period of the first month, the employee may claim the difference of twice the monthly salary for up to eleven months; if the contract is still not signed after one year, it shall be deemed that a non-fixed-term labor contract has been concluded, and the employer shall no longer continue to calculate twice the monthly salary thereafter. If the employer continues to employ the employee after the contract expires without renewing it, the same rules shall apply in practice. The specific number of months that can be claimed depends on the months that are still within the statute of limitations at the time of the arbitration application, so it is advisable to calculate and claim as early as possible.

Q2: What evidence do I need to prepare to claim double pay?

The evidence is organized around two main aspects: labor relations and wage standards. For labor relations, evidence can include bank payroll records, attendance clock-in records, work badges, WeChat work group records, social insurance or personal income tax payment records, audio and video recordings, etc. For wage standards, evidence can include transfer records, pay slips, compensation terms stated in recruitment information, and agreed amounts in chat records. Generally, the fact that no contract has been signed does not require workers to prove it themselves; the employer should provide evidence to prove that a contract has been signed. If the employer denies the existence of labor relations or wage standards, it shall bear the corresponding burden of proof and face adverse consequences if it fails to provide evidence.

Q3: Does it cost money to apply for labor arbitration, and how long does it take to get the result?

It doesn't cost anything. Article 53 of the "Law on Mediation and Arbitration of Labor Disputes" clearly stipulates that there is no charge for labor dispute arbitration, and the cost of the rights protection process is much lower than that of litigation. In terms of the trial period, the arbitration tribunal shall conclude the case within 45 days from the date of acceptance, and the case may be extended by no more than 15 days if the case is complex and approved; if the arbitration is not concluded within the time limit, the parties may bring a lawsuit to the people's court regarding the labor dispute. Adding the filing, service and subsequent possible litigation steps, the overall cycle often lasts for several months. Those claiming double wages should calculate the statute of limitations and the procedural cycle together.

Q4: I've been employed for over a year. Can I still claim double pay?

It needs to be reviewed on a monthly basis. The statute of limitations is calculated separately by month. After one year of employment, the double wages for the earliest months usually exceed the statute of limitations, while those for the recent months may still be within the one-year statute of limitations. The difference in double wages does not belong to labor compensation. Even if the labor relationship is still in existence, the statute of limitations is still calculated on a monthly basis. For those who have left the job, they should claim all the rights within one year after the termination of the labor relationship. If there are circumstances such as urging the employer to pay or complaining to the labor supervision authority before the statute of limitations expires, they can claim that the statute of limitations is interrupted and recalculated, but they need to keep the interruption evidence such as letters, chat records, and receipts. Otherwise, it will be difficult to counter the statute of limitations defense.

Q5: The company says it's an employment relationship. Do I still have a chance to get double pay?

The nature of the relationship is determined by the facts, not the name of the agreement. Whether the employee accepts attendance management, whether the compensation is paid on a monthly basis, and whether the work constitutes a part of the company's business are the core elements for determining the subordinate relationship. Even if no written contract is signed, the employee can still claim double pay if the relationship is deemed to be an employment relationship. If the relationship is packaged as a cooperation agreement and the employer substitutes wages with profit-sharing or dividends, the court will first determine whether the agreement's content is consistent with the actual performance. It is recommended to first evaluate the relationship based on the aforementioned list of evidence, and then entrust a lawyer to determine the nature of the relationship and the litigation strategy to avoid having the application rejected outright.

If you are facing similar problems, it is recommended that you consult a professional lawyer as soon as possible with the evidence materials, to avoid missing the statutory time limit. →Labor arbitration legal services·Attorney Tian Jiayan·Beijing Henglu Law Firm
