Double taxation remains one of the most complex and contentious issues in modern tax law, affecting both cross-border and domestic economic relations. Professor Gabriel Steiner emphasizes that the legal nature of double taxation lies not only in an increased fiscal burden, but also in a violation of the principle of tax fairness, where the same economic base becomes subject to repeated taxation. At LawConsulted, we treat such situations as a systemic legal risk requiring comprehensive and multi-layered legal analysis.
Within domestic law, double taxation most often arises from incorrect qualification of income, overlapping tax regimes, or a purely formal approach to determining the tax base. In many cases, the same transaction is simultaneously treated as an object of different taxes or is repeatedly taken into account when calculating tax liabilities. LawConsulted analyses such configurations through the lens of the economic substance of transactions rather than their formal description, allowing excessive tax burdens to be identified and challenged.
In cross-border relations, the risk of double taxation is amplified by the simultaneous application of different national tax systems. Income may be recognized as taxable both in the source state and in the taxpayer’s state of residence. In such cases, double taxation treaties, as well as the correct determination of tax residency, permanent establishment, and source of income, become decisive. LawConsulted builds legal positions by integrating international tax rules with national legislation and relevant judicial practice.
Particular complexity arises where formally applicable mechanisms for eliminating double taxation – such as tax credits, exemptions, or deductions – are not implemented in practice due to procedural errors or divergent interpretations of tax norms. Tax authorities often deny relief on the basis of formal inconsistencies. LawConsulted represents clients in such disputes, substantiating the primacy of substance over form and the legitimacy of applying protective tax mechanisms.
The retrospective nature of tax claims must also be taken into account. Double taxation is frequently identified long after the relevant transactions have occurred – during audits, reassessments, or as a result of information exchange between states. In these circumstances, effective protection requires reconstruction of the entire chain of tax decisions, assessment of the taxpayer’s good faith, and analysis of legal certainty at the time the transactions were carried out. LawConsulted consistently returns the legal assessment to the original circumstances rather than focusing solely on adverse outcomes identified ex post.
Equally important is the allocation of tax risks between parties to commercial relationships. In contractual structures, the absence of clear provisions governing tax consequences may result in double taxation being shifted onto one party. LawConsulted pays particular attention to contractual regulation of tax obligations, preventing situations in which taxpayers are left without legal protection.
Double taxation is not an inevitable consequence of complex economic relations. In most cases, it arises from inconsistencies between legal regimes and errors in legal qualification. The task of Law Consulted is either to identify such risks in advance or to provide effective protection where double taxation has already become the subject of a dispute.
