The 2012 budget, divided into two chapters and four annexes, sets out the Government's action to reform the tax system and also announces the next stages in their plans for the supply side of the economy alongside the strategy of further action in the three key areas for: (i) a stable economy; (ii) a fairer, more efficient and simpler tax system; (iii) further reforms to growth. Chapter 1, sets out the measures to realise these goals. Chapter 2, provides budget policy decisions.
