Shanghai's Changning district tax bureau has fined Pinduoduo 100,000 yuan for failing to submit required tax-related information under new rules governing online platforms.

The penalty was imposed on Shanghai Xunmeng Information Technology, the platform's operating entity, after it did not complete rectification within the prescribed period, the bureau said on January 21.

Under the Measures on Tax-Related Information Reporting by Internet Platform Enterprises, which took effect in 2025, platforms are required to submit tax information on merchants and workers operating on their services. Tax authorities said Pinduoduo failed to report the required data for the third quarter of 2025.

The Changning District Tax Bureau issued a rectification order in November 2025. While the company later took corrective steps, it did not complete them within the deadline, prompting the fine, the bureau said.
