Greece Introduces Binding Tax Rulings

Law 5301/2026 marks one of the most important developments in Greek tax administration in recent years by introducing, for the first time, a formal Binding Tax Ruling (BTR) procedure. Alongside this innovation, the new legislation also reforms several provisions of the Code of Tax Procedure concerning tax penalties and cash payment restrictions.

The new framework is expected to enhance legal certainty for taxpayers, particularly in complex domestic and cross-border transactions, while bringing Greece closer to the practices already followed in many other OECD and EU jurisdictions.

Introduction of Binding Tax Rulings

The centrepiece of the new legislation is the insertion of Article 9A into the Greek Code of Tax Procedure, establishing a formal mechanism through which taxpayers may request an advance interpretation of Greek tax legislation before implementing a planned transaction.

Unlike informal discussions with the tax authorities or non-binding administrative guidance, a Binding Tax Ruling provides legal certainty regarding the tax treatment of a future transaction, provided that the factual circumstances presented by the applicant remain accurate and unchanged.

The procedure is available to both individuals and legal entities and allows taxpayers to obtain certainty before significant commercial or investment decisions are implemented.

Scope of the New Regime

A Binding Tax Ruling is intended to resolve genuine questions concerning the interpretation of Greek tax or customs legislation arising from clearly identified future circumstances.

Importantly, the procedure is only available for transactions or situations that have not yet occurred. It therefore functions as a preventive mechanism, enabling taxpayers to assess the tax consequences before taking action rather than after an audit has commenced.

Matters Excluded from the Procedure

The legislation expressly excludes several categories of cases from the scope of the new regime.

These include:

• Advance Pricing Agreements relating to transfer pricing;
• Questions involving the application of foreign law;
• Matters already under administrative appeal or judicial review at the time the application is submitted.

Accordingly, the new procedure is designed as an advance planning tool rather than a mechanism for resolving existing tax disputes.

Timeframe for Issuing a Ruling

The Independent Authority for Public Revenue (AADE) must either issue the Binding Tax Ruling or reject the application within 150 days from the submission of a complete application together with the supporting documentation and payment of the applicable fees.

Applicants may also request expedited processing, although the detailed procedure is expected to be specified through a future administrative decision.

Binding Effect

One of the most important features of the new regime is that the ruling is binding on the Greek Tax Administration.

The protection remains in force provided that:

• the relevant facts remain unchanged;
• the applicable legislation is not amended;
• there is no contrary interpretation adopted by a supreme court; and
• the taxpayer complies with any conditions contained in the ruling.

Furthermore, where a taxpayer has acted in accordance with a valid Binding Tax Ruling, the corresponding tax return cannot subsequently be treated as inaccurate merely because the tax administration later adopts a different interpretation.

Cost of Obtaining a Binding Tax Ruling

The new procedure is aimed primarily at complex or high-value matters.

An application requires payment of a non-refundable minimum fee of €3,500, while the total fee may range from €10,000 to €50,000, depending on factors such as:

• the complexity of the legal issues;
• the number of questions submitted;
• the size and legal form of the applicant; and
• whether expedited treatment has been requested.

If AADE rejects the application within the statutory deadline, the amount exceeding the minimum €3,500 fee is refundable.

Although the fees are significant, they may prove commercially justified for major restructurings, mergers and acquisitions, investment projects, inbound investments, international tax planning, or transactions involving substantial tax exposure.

Publication of Rulings

The legislation also introduces an important transparency element.

Binding Tax Rulings will be published on AADE’s website in anonymised or pseudonymised form. Applicants may request that commercially sensitive information or trade secrets be omitted from publication.

Over time, these published rulings are likely to become a valuable source of administrative guidance, contributing to greater consistency in the interpretation of Greek tax legislation.

Changes to Tax Penalties

Law 5301/2026 also introduces several taxpayer-friendly amendments to the penalty regime.

Among the most significant changes are:

• penalties are now expressly imposed for late VAT returns even where no VAT is payable;
• various exemptions are introduced for low-value tax liabilities (generally up to €100);
• relief is provided for certain late amended returns;
• new protections are introduced for minors and returns relating to income earned during minority;
• several of these favourable provisions apply retroactively, requiring previously imposed penalties to be cancelled or refunded where appropriate.

These amendments simplify the penalty framework while reducing disproportionate sanctions in cases involving minimal tax consequences.

Stricter Cash Payment Rules

The legislation also strengthens the prohibition on accepting cash payments exceeding €500 in transactions with private individuals.

Rather than focusing solely on retail tax documents, the revised provision now applies more broadly to the underlying transaction itself. Businesses accepting prohibited cash payments face an administrative fine equal to twice the value of the transaction paid in cash.

This reinforces the Greek authorities’ continued emphasis on electronic payment methods and combating tax evasion.

Secondary Legislation Expected

The law authorises the Governor of AADE to issue a detailed decision regulating the practical operation of the Binding Tax Ruling procedure, including:

• the required contents of applications;
• supporting documentation;
• examination procedures;
• communication with applicants;
• payment and refund of fees; and
• the operational aspects of issuing rulings.

This secondary legislation will be crucial in determining how efficiently and practically the new regime operates in practice.

Conclusion

The introduction of Binding Tax Rulings represents a significant modernisation of the Greek tax system. For the first time, taxpayers undertaking complex transactions will have access to a statutory mechanism for obtaining binding certainty regarding the interpretation of Greek tax legislation before implementing their plans.

While the relatively high application fees mean that the procedure is likely to be reserved for substantial transactions, the ability to secure binding certainty may prove invaluable for major investments, corporate reorganisations, international tax planning and cross-border business activities.

Together with the accompanying reforms to tax penalties and payment rules, Law 5301/2026 reflects a broader effort to modernise the Greek tax administration and improve predictability for taxpayers operating in Greece.
