Details of the new Czech Republic-Norway income tax treaty, signed on 19 October 2004, have become available. The treaty entered into force on 9 September 2005 and will generally apply from 1 January 2006. From this date, the new treaty will generally replace the Norway-former Czechoslovakia income and capital tax treaty and protocol of 27 June 1979 in respect of relations between Norway and the Czech Republic. The treaty was concluded in the English language. The treaty generally follows the OECD Model Convention and is probably one of the first treaties to contain the text of the Exchange of Information article (Art. 25) in the form included in the 2005 OECD Model update. It should also be noted that the treaty deals with mutual assistance in the collection of taxes between the Czech Republic and Norway (Art. 26).
