Small firms account for 56% of UK tax gap
Figures from the taxman suggest that small businesses made up 56 % of the tax gap in a single year, equivalent to £20.2bn, say law firm Pinsent Masons.
This figure has risen for four consecutive years, with small businesses believed to be responsible for 40 % (£12.8bn) of the tax gap in 2017/18.
The tax gap is what should theoretically be collected by HMRC and what is collected.
Steven Porter, partner and head of tax disputes and investigations at Pinsent Masons, said: “HMRC is really shifting its attention to small businesses. It has worked hard to reduce the amount of tax that goes unpaid from large businesses and high net worth individuals – but it still has a lot of work to do on SMEs.”
He added that HMRC’s focus on large businesses and wealthy individuals means that small businesses get less attention. Investigations into small businesses anecdotally often take longer to complete and problems can persist for years.
“For example, there are cases of small businesses continuing to use tax avoidance schemes for years after they were virtually wiped out among large businesses and high net worths,” he said.
“Small businesses that aren’t tax compliant should not be surprised if they are investigated by HMRC over the next couple of years. That’s clearly the direction that HMRC looks set to go into based on these figures. Getting out ahead of that problem by taking professional advice would be a very good idea at this point.”
The tax gap has held steady at 4.8 % (£35.8bn) of all tax theoretically due – the same as last year.
Figures from the government’s latest Measuring tax gaps report show that at 56 % (£20.2bn), small businesses make up the largest proportion of the tax gap by group, followed by criminals (£4.1bn), large businesses (£3.9bn) and mid-sized businesses (£3.8bn). Wealthy individuals account for 5 % (£1.7bn) of the tax gap while all other individuals account for 6 % (£2.1bn) of the tax gap.
Income Tax, National Insurance contributions and Capital Gains tax make up 35 % of the tax gap when measured by type of tax. The VAT gap continues to narrow, falling from 14 % (£11.9bn) in 2005/6 to 5.4 % (£7.6bn) in 2021/22.
Failure to take reasonable care (30 %), error (15 %), evasion (13 %), legal interpretation (12 %) criminal attacks (11 %) and non-payment (9 %) are cited among the main behavioural reasons for the tax gap, according to the report.
