Wolters Kluwer Tax & Accounting Spain has released the fourth edition of its annual Advisory Barometer, a report that provides insight into the current landscape and future direction of the tax, accounting, and labor sectors in Spain, highlighting trends in digitalization, technological transformation, and regulatory changes, particularly those affecting invoicing.The report explores the sector’s shift towards a more consultative business model and analyzes ongoing regulatory changes, with a specific focus on their implications for professional firms. Tomàs Font, Vice President & General Manager at Wolters Kluwer Tax & Accounting Europe South Region, stated, “The Advisory Barometer 2025 once again puts on the table the most immediate challenges for professional firms, starting with the regulatory changes in the area of invoicing, which will have a profound impact on companies and will require them to accelerate their digitalization.” Font added that nearly two-thirds of advisors are already actively guiding their clients to prepare for these changes, indicating the sector’s role in helping companies adapt to the transformation of invoicing processes.A key finding from the barometer indicates that 63% of advisors are actively recommending that small and midsize enterprises (SMEs) anticipate upcoming legal changes in invoicing. However, 55% of advisors believe these businesses are not adequately prepared.
