For tax information prior to 2019, taxpayers can go to a tax service hall to apply for a "Tax Payment Certificate" (税收完税证明) (in document format) and an "Individual Income Tax Payment List" (个人所得税纳税清单) through the Golden Tax System (Phase III). (Note: The payment list does not include information about the withholding entities.)
For other other tax-related inquiries, feel free to call the tax payment hotline at +86-10-12366 (Service hours: 9:00-17:30 on working days, with multilingual services offered).
