To ask the Chancellor of the Exchequer, how much tax revenue accrued to the public purse from small and medium-sized enterprises in (a) 2013-14, (b) 2014-15, (c) 2015-16, (d) 2016-17 and (e) 2017-18.

Total tax revenue accrued by small and medium-sized enterprises was estimated to be around a) £160bn in 2013/14, and b) around £170bn in 2014/15. Equivalent estimates for later years are not readily available, but an estimate for 2015/16 will be available in Autumn 2018.

These estimates include Self-Assessment Income Tax and Class 4 National Insurance Contributions (NICs), Corporation Tax, VAT, and Pay As You Earn Income Tax and Class 1 NICs. The definition of small and medium-sized enterprises used is consistent with the EU definition where possible.

HMRC works to collect the tax due under UK law from all businesses, large or small, in the most cost effective way.
