Ambrus I. – Erdős G. – Horányi M. – Őry T.: Magyarázat a compliance jogszabályairól II. – Adó- és versenyjogi compliance, WoltersKluwer, 2023, ISBN: 978 963 594 194 0

The book is the second volume of a series that deals with issues of tax and competition law compliance. Inadequate fulfillment of tax obligations entails sanctions, regardless of whether the non-compliance is the result of intent, negligence, or misinterpretation of the law. Tax procedure gives the framework for the realization of tax standards. At the same time, compliance covers a wider area than the tax procedure, as it includes voluntary legal compliance as well as the rules for fulfilling tax obligations, control, sanctions and the tax administration procedure. The tax law part of the volume places special emphasis on the domestic implementation of international rules, the exchange of information and dispute resolution procedures.

A könyv egy sorozat második kötete, amely az adójogi, majd a versenyjogi compliance kérdéseit járja körül. Az adókötelezettség nem megfelelő teljesítése szankciókat von maga után, függetlenül attól, hogy a nem-megfelelés szándékosság, gondatlanság, vagy téves jogértelmezés következménye. Az adóeljárás az, amely az anyagi adónormák realizálásának kereteit rendezi. Ugyanakkor a compliance szélesebb területet fog át, mint az adóeljárás, hiszen magában foglalja az önkéntes jogkövetést éppúgy, mint az adókötelezettség teljesítésének szabályait, az ellenőrzést, a szankciókat és az adóigazgatási eljárást. A kötet adójogi része kiemelt hangsúlyt helyez a nemzetközi elvárások hazai leképezésére, az információ cserére és a vitarendezési eljárásokra.


Erdős, G: Bitcoin, a lejárat nélküli követelés? (Bitcoin, a receivable without due date?), Iustum Aequum Salutare, 2020/4, ISSN 1787-3223 (Print), ISSN 2498-535X (Online)


Abstract: Cryptocurrencies are gaining in popularity worldwide. They are used as if they were currencies, securities, debt or equity instruments, or property. They are neither of those things although they certainly show characteristics of each categories. A Hungarian non-binding ruling classifies them as claims or accounts receivable, while the international accounting standards recommend to present cryptocurrencies either as intangible assets or as inventories. The article analyses the characteristics of cryptocurrencies, and the corporate income tax consequences of following the recommendations of the Hungarian non-binding ruling. It shows why the wrong classification of cryptocurrencies leads to false tax results. The author recommends the withdrawal of the tax ruling and the establishment of new accounting rules and interpretations – possibly also the introduction of a new accounting category for cryptocurrencies.

Erdős G.: Taxation of Sportsmen and their clubs in Hungary, in Global Sports Law and Taxation Reports, 2013/4, 37-39, ISSN: 2211-0895

Abstract: Hungary has a unique system for financing capital investments and youth development by way of granting a tax credit for companies donating cash to sport organizations. The earlier paper summarizes the most prominent features of the system. The other paper goes through the conditions established by the European Commission and analyzes how much the Hungarian system has fulfilled them in practice. The article focuses on three general areas, the achievements of the system; the public financing character of the tax incentive; and some unintended effects.
