Our lawyers and professional partners provide support in tax disputes, challenging decisions issued by regulatory authorities, managing tax audits, and preparing formal submissions, appeals and other legal documents.
Another important area of our work is advising on the determination of tax status for individuals and companies, the taxation of income earned in different countries, the application of double taxation treaties, and compliance with legal requirements relating to foreign assets and overseas sources of income.

How a Tax Lawyer Can Help
Businesses and individuals regularly encounter questions concerning the interpretation and application of tax legislation, audits, tax assessments and other statutory payments, tax residency, income reporting and dealings with public authorities.
Our lawyers and professional partners advise on taxation matters, assess potential liabilities, prepare formal submissions, appeals, legal information requests and written legal opinions, assist throughout tax compliance and enforcement procedures, and represent clients in administrative appeals and court proceedings.
We also provide legal support in relation to international taxation, foreign-source income, overseas assets, investment activities, cross-border financial transactions and the application of international double taxation treaties.
Every matter is reviewed on its individual merits, with due regard to the relevant facts, governing legislation and jurisdiction-specific requirements.
Tax Residency for Individuals and Businesses
Tax residency plays a significant role in determining where an individual or company is required to fulfil tax obligations and report income.
In practice, residency questions frequently arise when relocating to another country, living abroad for extended periods, operating an international business, receiving income from multiple jurisdictions, holding foreign assets or establishing companies overseas. An incorrect assessment of tax residency may result in additional tax assessments, penalties, disputes with government authorities and exposure to double taxation.
Legal assistance in these matters includes reviewing the relevant facts, examining domestic legislation and international tax treaties, preparing supporting documentation and developing a legal position to protect the client's interests.
The assessment takes account of the laws of the country concerned, the structure of the client's assets and the particular circumstances of the case.
Tax Legal Services for Foreign Nationals
Foreign nationals, business owners and investors often need legal advice on taxation in different countries. Particularly complex situations can arise when income is earned across several jurisdictions, an individual changes their country of residence, a company is established abroad, property is purchased, investments are made or international financial transactions are undertaken.
Our legal professionals assist clients in identifying the jurisdictions in which tax obligations may arise, establishing applicable income reporting requirements, assessing the implications of cross-border transactions and preparing the documentation required when dealing with government authorities.
We also assist with obtaining official documents, certificates, extracts and information from public registers needed to address tax and financial matters. Where appropriate, we involve local partners and specialist professionals in the relevant countries to support international projects and safeguard our clients' interests.
International Taxation
International taxation requires consideration of the laws and regulations of multiple jurisdictions.
Owners of foreign companies, investors, entrepreneurs and private individuals may need to address questions concerning the determination of the relevant tax jurisdiction, taxation of overseas income, application of international tax treaties and compliance with financial reporting obligations.
Tax Disputes and Appeals Against Tax Authority Decisions
Tax disputes can affect individuals and businesses alike. In practice, they frequently arise from tax audit findings, additional assessments, penalties, income reporting requirements, the tax status of individuals and companies, the deductibility of expenses, refunds of overpaid tax or differing interpretations of statutory provisions. Disagreements may also concern international financial transactions, the activities of foreign companies, overseas income, investment projects and property transactions.
In many cases, a dispute begins when a taxpayer receives a notice, formal demand, audit report or another document issued by the relevant authority. Reviewing the circumstances promptly helps identify potential risks, establish a defensible legal position and determine the most appropriate course of action. Depending on the nature of the matter, resolution may involve preparing explanations and supporting documents, negotiating with the authorities, pursuing an administrative appeal or bringing the case before a court.
How We Handle Tax-Related Matters
Our work begins with reviewing the available documents and examining the circumstances of the particular case. During the initial assessment, we identify the applicable legal framework, evaluate potential risks and consider the available options for resolving the matter. The client then receives recommendations on the next steps, the documentation required and possible legal remedies.
Depending on the nature of the issue, our services may include drafting formal submissions, applications, information requests, appeals and other documents; assisting with communications and proceedings involving government authorities; obtaining information from official registers; participating in negotiations; and representing the client's interests. Where necessary, we work with specialist professionals and partners in other countries on international matters involving commercial operations, investments, assets and cross-border financial transactions.
Tax Lawyer Fees and Legal Service Costs
The cost of legal assistance depends on the complexity of the matter, the scope of work required, the volume of documentation, the jurisdiction whose laws apply, and whether dealings with government authorities, courts or foreign institutions are necessary. As each case requires an individual assessment, the final fee is determined after reviewing the circumstances and the client's specific requirements.
Certain services may be provided as standalone consultations, document preparation or written legal opinions. More complex engagements involving tax disputes, international taxation, ongoing business support, and representation before public authorities or courts are priced individually, taking into account the anticipated workload and timeframe. To obtain an initial fee estimate, you may send us a description of your circumstances together with any relevant documents for review.
Tax matters call for an individual approach and careful analysis of the legislation applicable in the relevant country. Our lawyers and professional partners advise individuals and businesses on taxation, represent clients before tax authorities and courts, and provide legal support for international tax matters across multiple jurisdictions.
