The article deals with the development and description of the Czech accounting system from early nineties of last century till present time as a background for IFRS implementation. Then the article followed subsequent steps of IAS 12 implementation into the hierarchy of legal rules for accounting, starting with the Act on accounting, decree on business entities and Czech accounting standard for deferred taxes. IAS 12 implementation into Czech accounting system is an example of partial and incomplete implementation of IFRS into domestic accounting rules based on different law presumption than under which are IFRS developed.
