The estimated financial impact assumes proclamation occurs by the end of 2014 except in relation to the MRRT which does not include any revenue that may be received between 1 July 2014 and proclamation.

Forgone MRRT revenue has been re-costed to reflect the latest estimate, which takes into account recent instalment data and the current forward estimates period. This change represents a downward revision normally captured as an estimates variation.

The increase in the instant asset write-off threshold from $5,000 to $6,500 was intended to be funded by revenue expected from the carbon tax. The financial impact of the reduction of the part of the threshold associated with the carbon tax from $6,500 to $5,000 results in a gain to revenue of $350m over the forward estimates period, comprising $50m in 2014-15, $150m in 2015-16, $100m in 2016-17 and $50m in 2017-18.

The costing for this measure includes the changes as announced in the 2013-14 MYEFO and the 2014-15 Budget.
