Adókulcsú

Adókulcsú, also known as tax key or tax identifier, is a unique code assigned to individuals and legal entities for tax purposes in Hungary. It serves as a primary identifier for tax administration and is used in various tax-related processes, including tax declarations, payments, and audits. The adókulcsú is a 13-digit number that is generated based on specific criteria, including the taxpayer's personal or business details.

The adókulcsú is issued by the National Tax and Customs Administration (NAV) and is essential for ensuring accurate and efficient tax collection. It is used to match tax declarations with the correct taxpayer and to verify the accuracy of reported income and expenses. In addition to its primary role in tax administration, the adókulcsú is also used for other purposes, such as identifying taxpayers in legal and administrative processes.

The adókulcsú is a crucial component of Hungary's tax system and plays a vital role in ensuring the integrity and fairness of the tax administration. It is important for taxpayers to keep their adókulcsú up-to-date and to use it correctly in all tax-related communications and transactions. Failure to do so may result in delays, errors, or other issues in the tax administration process.
