This is a book to rave about, but not unconditionally. It sets out to describe the public sector in figures - how much is raised from what and how much is spent on what. In doing that, it works really well.
It provides a clear explanation of the main sources of tax income, split between the various forms of tax, along with a variety of other income sources. What I particularly liked was the sense of scale that it brought to the analysis. For example, income tax brings into the Exchequer about 34 times more than inheritance tax. Or VAT brings in about 10 times capital gains tax. I see this as an important comparator when talking vaguely about tax policy.
The same form of approach is taken to the expenditure side. It threw up a number of surprising conclusions for me. For example, expenditure on working age benefits and credits is broadly the same as the state retirement pension. That suggests to me that the old canard about young workers funding the lifestyles of old pensioners is not entirely based upon fact. Taxpayers are also funding those of working age.
The book also allows us to link together income and expenditure in a fairly useful way. For example, national insurance receipts very nearly equal the spending on the health service. I find that a useful piece of information because the NI system was originally supposed to fund the NHS. The obvious implication is that if we want to raise the funding for the NHS, we will need to raise NI levels.
However, this is a step too far for the book. It takes pains to describe what is and to steer clear of what ought to be. I see this as a weakness because it suggests that we live in the best of all possible worlds. This is a view widely touted by the UK Civil Service, but it is far from the mark. After all, politics is all about shifting priorities in spending and income. The book provides some good source information to fuel these discussions, without actually stating the preferences of the author.
For example, there are those who might say that inheritance tax only raising 1/34th of income tax is wrong. They might argue that inheritances from rich people to their heirs ought to raise a larger amount of income. The numbers suggest that even if the inheritance tax take was doubled, after allowing for avoidance and mitigation schemes, it would only allow, for example, a 12% increase in the schools budget. Not to be sneezed at, but not a significant amount, either.
The book is an historical account of income and spending in 2022-23. In setting it out, it highlights the strengths of the Treasury approach, but also it's pitfalls as well. The account is not forward looking, other than vague reference to future events, such as increasing number of Boomers retiring. There is a sense of where we have been, but not much sense of where we are heading. This allows for some misleading conclusions to arise. One large impending budget item that the author has missed is the cost of servicing the public debt. In some forecasts, debt servicing in two or three years time will be larger than the defence budget.
Equally, the author assumes that the current structure may not change. We might ask, however, how sustainable the structure might be with ever increasing amounts of debt being added to the existing pile? There is little to help that conversation in this book.
All in all, there is much to commend this book. It has its drawbacks, but it is very useful in what it does. The author writes in a clear and accessible style. He avoids jargon and takes pains to explain the concepts as clearly as possible. As an introduction to the finances of the UK public sector, there is much to commend in this book.
