Tax Law
Tax Law and Tax Litigation
Tax Law is a highly technical branch of law that regulates taxes imposed by the state pursuant to its sovereign authority, as well as the rights and obligations of taxpayers. Even a minor procedural error in acts carried out by the tax administration (Revenue Administration, Tax Offices, Customs Authorities), or a taxpayer’s failure to exercise their rights within statutory time limits, may result in irreparable financial losses and substantial administrative penalties.
Zengin & Aydın Law Firm approaches the taxation process not merely as a financial matter, but as a legal one. For taxpayers seeking a tax law attorney in İzmir, we provide comprehensive legal protection from the initiation of tax audits through pre- and post-assessment settlement stages, and throughout litigation before tax courts.
