1. Ensure the accuracy and reliability of information: PDF is a cross-platform and readable file format, which can ensure that documents will not be garbled or typeset inconsistently due to different operating systems or fonts during transmission.
2. Improve the security of documents: PDF documents can be protected by passwords, and operations such as printing and copying are restricted to effectively protect the security of document contents.
3. Facilitate the publication and dissemination of documents: PDF documents can be published and disseminated conveniently on the Internet, enabling taxpayers to obtain relevant tax information anytime and anywhere.
4. Meet different needs: PDF documents can contain words, pictures, tables, hyperlinks and other elements, which can meet the needs of different taxpayers and provide more detailed and comprehensive tax information.
