Our comprehensive tax and audit services
Auditing
We see auditing as a strategic advantage for our clients – as external validation of the reliability of financial data and as a decision-making tool for company management.
Tax Advisory
Due to fierce market competition, it is necessary to have a broader and deeper understanding of international tax law than before, which makes it inevitable for companies to entrust the coordination of their tax activities to external experts.
Transfer pricing advice
The issue of prices applied between related companies (transfer prices) is becoming increasingly important. Experience gained in recent years shows that the tax authorities are also focusing more and more on this area.
Management Accounting & Business Consulting
Establishing a solid business foundation in itself provides numerous opportunities for companies. DIAMANT Könyvvizsgáló Kft. can also provide solutions for your company in the development of a comprehensive financial support system.
Forensic expert services
Independent expert reports, preparation of expert opinions in litigation cases and reports for official assignments, courts and other authorities, as well as forensic bookkeeping, tax and contribution expertise.
