Internal invoice – what is it and when can it be issued?

Although the term internal invoice is still used in everyday language, it has no longer been in use in the tax circuit since 2013 – it was then that a regulation of the Minister of Finance introduced the term ‘internal taxation document’, which is in force today. Nevertheless, until now the terms are often used interchangeably.
