Tax Number Cancellation in Hungary – What Can You Do?
Tax number cancellation in Hungary – quick overview
Tax number cancellation means that the Hungarian Tax Authority (NAV) withdraws a company’s tax identification number. Without a valid tax number, the company cannot legally conduct business activities or issue invoices. The cancellation is often caused by administrative issues such as missing tax returns or financial statements. In many cases, the tax number can be restored if the missing obligations are fulfilled and the appropriate request is submitted.
Tax number cancellation – What can you do if NAV has cancelled your company's tax number?
If NAV has cancelled your company's tax number, or the tax authority has warned you about the risk of your tax number being cancelled, it is important to act quickly. Tax number cancellation can have serious consequences: the business cannot carry out economic activities, cannot issue invoices, and can even lead to the company being dissolved.
However, it is important to know that in many cases it is possible to restore the tax number if the deficiencies are corrected and the appropriate legal steps are taken in a timely manner.
