Travel tax can't be found in Shandong Electronic Taxation Bureau, so it needs to be inquired offline by the Taxation Bureau. Travel tax is paid by Alipay in the Electronic Taxation Bureau, and no identity information can be found. According to the relevant information, the travel tax is not paid in the tax bureau, but the travel tax paid in Alipay belongs to Alipay's sale, which requires Alipay officials to inquire in the tax bureau.
