Implementing the new system requires appropriate organizational, technical, and accounting preparation.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>KSeF will be mandatory starting February 1, 2026, for the largest taxpayers and from April 1, 2026, for other entrepreneurs.<\/strong><\/p>\n\n\n\n<h3 class=\"wp-block-heading\">What is KSeF?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">KSeF is an IT system of the Ministry of Finance used for issuing, receiving, and storing structured invoices.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">Structured invoices<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">Documents issued in KSeF have a uniform XML format, allowing data to be automatically processed by accounting systems.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">Document Archiving<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">Invoices submitted to KSeF will be stored for 10 years, which limits the need for independent document archiving.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">Changes in corrections<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">The system provides a unified way to correct documents through credit invoices.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">Faster VAT refund<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">Entrepreneurs using KSeF can get a faster VAT refund.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">What does KSeF implementation look like?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The implementation process requires an analysis of current accounting processes and their adaptation to new requirements.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">1.
