This report by the National Audit Office, made under sections 156 and 157 of the Finance Act 1998, examines the conventions and assumptions underlying the Treasury's fiscal projections within the 2006 Budget (HCP 968, session 2005-06; ISBN 0102937311).

This report by the National Audit Office, made under sections 156 and 157 of the Finance Act 1998, examines the conventions and assumptions underlying the Treasury's fiscal projections within the 2007 Budget (HCP 342, session 2006-07; ISBN 9780102944556).

The Chancellor of the Exchequer asked the National Audit Office to audit two new assumptions underlying the Treasury's fiscal projections within the 2009 Budget (HC 407, session 2008-09, ISBN 9780102959161). Firstly, to assess if the 2008 Pre-Budget report assumption for the trend rate of growth, allowing for a downward adjustment to the trend output level of around 4 per cent, for the post-2006 period, together with the further downward adjustment at Budget 2009 to the trend output level of around 1 per cent, is reasonable and cautious. Secondly, to examine whether the approach used by the Treasury to produce estimates of the fiscal aggregates adjusted for the effects of the economic cycle is reasonable.

Audits provide essential accountability and transparency over government programs. Given the current challenges facing governments and their programs, the oversight provided through auditing is more critical than ever. Government auditing provides the objective analysis and information needed to make the decisions necessary to help create a better future. The professional standards presented in this 2018 revision of Government Auditing Standards (known as the Yellow Book) provide a framework for performing high-quality audit work with competence, integrity, objectivity, and independence to provide accountability and to help improve government operations and services. These standards, commonly referred to as generally accepted government auditing standards (GAGAS), provide the foundation for government auditors to lead by example in the areas of independence, transparency, accountability, and quality through the audit process. This revision contains major changes from, and supersedes, the 2011 revision.
