The documents connected to the Autumn Statement include an interesting table which shows that the majority of the additional deficit reduction the OBR is now forecasting will come from increased tax revenue.
In 2014-15 an additional £9.6bn of tax is 77% of the extra deficit reduction (compared to the March position). In 2015-16 £13.2bn of extra tax is 79% of the extra deficit cut, and in 2016-17 ££14.5bn of extra tax is 91%.(OBR Table 1.3 p.14).
Some of this revenue is the result of the higher growth forecasts, but some of it comes from the so called anti avoidance measures. These are tax rises of one sort or another, altering the way existing taxes are levied. The government aims to get more tax from people and companies who are currently paying the correct amount under current tax law, so they are in that sense tax rises.
Many will say because they are called anti avoidance measures they are all justified. Nonetheless these new tax measures need examination to see who they take more tax from, and what economic impact that will have. If you stop a legal way of avoiding tax you may also stop certain types of economic activity that depended on the favourable tax treatment.
Meanwhile the Chancellor correctly underlined the fact that the structural deficit remains obstinately high. The reason for that is very simple. Current public spending has continued to rise in real terms, with a starting position in 2010 where there was an inbuilt large structural deficit from high spending.
If these forecasts are correct, the UK state debt (excluding pensions) peaks at 80% of our GDP instead of at 85% under the March 2013 Budget plans. Most of this is down to these further increases in tax.
