PAYE tax gap reduced in 2017-18

20 June 2019

HMRC has published the latest figures for 2017-18 which reveal that the UK’s overall tax gap is now 5.6%, a slight increase of 0.1% on last year’s figures.  However, with one of the lowest gaps of all taxes, the PAYE tax gap reduced from 1.1% in 2016-17 to 1% in 2017-18.

The tax gap is the difference between the amount of tax that should, in theory, be paid to HMRC, and what is actually paid. The tax gap is a useful tool for HMRC to understand the relative size and nature of non-compliance. Despite the slight increase this year HMRC has still collected 94.4% of all the tax due under the law in 2017 to 2018. Overall, the tax gap has fallen from 7.2% since 2005-06, with the Office for Statistics Regulation stating that

“HMRC is world-leading in measuring tax gaps and is setting the bar for others to follow”.

In 2017-18, the total estimated tax gap for income tax, National Insurance contributions and Capital Gains Tax is £12.9 billion which equates to 3.9% of total theoretical liabilities.

Of this £12.9 billion, £7.4 billion is attributable to Self Assessment taxpayers, meaning that the tax gap was 14.9% of theoretical liabilities.

In contrast, £2.9 billion of the income tax, National Insurance contributions and Capital Gains Tax gap comes from employers, where money is deducted at source, which translates into a tax gap of 1.0% of theoretical liabilities.
