UK tax gap falls to 6.4%

The tax gap for 2013 to 2014 was 6.4% of tax due, continuing a long-term downward trend, reflecting that HMRC's approach is delivering steady and sustained progress.

The tax gap, which is the difference between the amount of tax due and the amount collected, has fallen from 8.4% in 2005 to 2006, annual figures released today by HMRC show.

This reduction in the percentage tax gap since 2005 to 2006 represents an additional £57 billion in cumulative tax collected over the eight-year period.

The largest reduction is in the Corporation Tax gap which has halved since 2005 to 2006, from 14% to 7% of relevant tax liabilities. There has been a sustained downward trend for both large and small businesses, with the overall reduction driven mainly by large businesses.

David Gauke, Financial Secretary to the Treasury, said:

The UK has one of the lowest tax gaps in the world, and this Government is determined to continue fighting evasion and avoidance wherever it occurs.

If the tax gap percentage had stayed at its 2009 to 2010 value of 7.3%, £14.5 billion less tax would have been collected.

There is understandable anger when individuals or companies are perceived not to be contributing their fair share, but we can reassure the public that the proportion going unpaid is low and this government is dedicated to bringing it down further.

Edward Troup, HMRC’s Second Permanent Secretary and Tax Assurance Commissioner, said:

The long-term downward trend shows that our approach to non-compliance is delivering solid and sustained progress.

We are committed to reducing the tax gap further and bringing in more money to fund vital public services. We are continuously looking for new ways to improve compliance and tackle non-compliance, whether by helping individuals do the right thing or by cracking down on offshore tax evasion by the wealthy or tax avoidance by multinationals.

The government invested almost £1 billion over the last Spending Review period to transform HMRC’s approach to compliance and close the tax gap. This investment contributed to the delivery of more than £100 billion in additional compliance revenues over the Spending Review period to the end of 2015 to 2016.

On top of this, at the Summer Budget, the Chancellor announced a range of new measures including £800 million of investment over the parliament, to strengthen HMRC’s ability to tackle evasion, reduce avoidance and improve voluntary compliance, including using data to identify and tackle tax risks more effectively.

In 2013 to 2014, HMRC brought in £505.8 billion in tax revenue for public services and secured £23.9 billion of compliance yield – money that would otherwise have been lost to the Exchequer. HMRC has built on this and last year (2014 to 2015) brought in a record £517.7 billion in tax revenue and secured £26.6 billion in compliance yield.
