Tiivistelmä
This thesis was conducted to address a practical need within an accounting company by creating a comprehensive VAT reporting guide for accountants in Finland. VAT reporting was identified as a critical monthly accounting obligation due to its frequency, complexity, and the financial risks associated with incorrect reporting. The thesis focused particularly on supporting junior accountants, who are assigned VAT responsibilities early in their careers and may lack the practical experience required to identify reporting errors independently. The scope of the thesis was limited to Finnish monthly VAT filing processes and concentrated specifically on two reporting methods: Procountor and Omavero.
The theoretical framework of the thesis was based mainly on Finnish VAT legislation, and official Tax Administration guidance. The theory section examined core principles of VAT. This theoretical basis was necessary to ensure that the practical instructions were accurate and reliable. The approach combined theoretical research with practice-based development. Existing VAT literature and legislative guidance were reviewed first. The guide was developed through workplace observation during VAT filing processes in February 2026. Prior academic knowledge and practical accounting experience were applied to identify recurring errors, and the most common problem areas faced by accountants. The guide creation process included documenting filing routines, drafting instructions, gathering and revising the final product accordingly.
The results of the thesis were the successful creation of a VAT reporting guide designed to improve reliability, and onboarding efficiency The final guide combines legal theory with practical accounting procedures, provides users with step-by-step instructions, and filing method considerations. Reliability was strengthened by the use of legal sources and repeated peer review. The thesis demonstrated that prior workplace learning, and process development can be transformed into a practical tool. The thesis provided immediate value for the commissioning company, by enhancing the author’s own professional expertise, and established a foundation for future development of the guide.
