Looking at the election manifestos of the Conservative, Labour and Liberal Democrat parties, there is some common ground as well as some big differences on business tax issues.

Headline corporation tax rates: back to the Future

These three political parties are all referencing their headline Corporation tax rate against a previous year:  the Conservatives are freezing rates at the 19% introduced in April 2017; the Liberal Democrats are pinning it back up to the 2015 rate of 20%; and over three years Labour would take it back up to the April 2011 rate of 26% by 2022. The SNP would oppose ny cuts to corporation tax.

Business tax reliefs:  under review

All the parties have also signalled a review of business tax reliefs.

The Conservatives have promised to redesign the tax system so that it boosts growth.  Their manifesto proposes to increase R&D tax credits to 13% and review the definition of R&D so that areas such as cloud computing and data are also incentivised. 

The Liberal Democrats are also proposing to allow companies to claim R&D tax credits against the cost of purchasing datasets and cloud computing and they have previously suggested a more standardised, simplified approach to tax reliefs. 

Labour has proposed a thorough review of corporate tax reliefs, to report after 6 months with a view to generating £4.3 billion of savings by 2024. A phasing out of R&D tax credits for large corporations and the Patent Box is also proposed, whilst keeping the R&D tax relief for smaller companies.

Tax transparency and enforcement:  more action by any government

The Conservatives propose measures to tackle tax evasion and reduce opportunities for aggressive tax avoidance, with a new anti-tax avoidance and evasion law that would:

·       Double the maximum prison term to 14 years for those convicted of the most serious tax fraud

·       Create a single, beefed-up Anti-Tax Evasion unit in HMRC that covers all duties and taxes from individual errors to deliberate non-compliance - which is put on a legislative footing

·       Consolidate existing anti-evasion and avoidance measures and powers

·       Introduce a new package of anti-evasion measures including measures to end tax abuse in the construction sector, illicit tobacco packaging and further measures to avoid profit-shifting by multinational companies to avoid paying taxes.

In addition, the Conservative manifesto pledges to Implement the Digital Services Tax, a 2% tax from April 2020 on the revenues of search engines, social media platforms and online marketplaces which derive value from UK users.

Labour propose to launch ‘’the biggest ever crackdown on tax avoidance and evasion". They have set out plans for an extensive Tax Transparency and Enforcement Programme  (https://labour.org.uk/Fair-Tax-Programme-2019) which includes:

·       Measures to improve transparency, including extending the register of beneficial ownership and an inquiry into the finance sector.

·       Abolish non-dom status

·       Stronger law, enforcement, and support for HMRC including a specialised Tax Enforcement Unit 

·       Eliminating legal loopholes: including action against ‘umbrella agencies’, introducing up-front payments for fragmented profits cases and tightening ‘anti enveloping’ rules. 

·       Cross-border action on avoidance and evasion, including minimum standards for Crown Dependencies and overseas territories and a withholding tax for ‘abusive’ tax havens 

This is a very detailed programme with a lot of new measures, so worth checking the detail (or ask your tax adviser).

As regards multinational corporations, Labour proposes treating groups of companies under common ownership as unitary enterprises so that profits are treated as arising where economic activity occurs or value is created using formulary apportionment.

The Liberal Democrats have also set out a range of activity including a new General Anti-Avoidance Rule, further action on profit shifting, setting a target for HM Revenue and Customs to reduce the tax gap and investing in more HMRC staff. 

The SNP manifesto also backs improvements to tax collection and tougher action on tax avoidance and evasion, including a review of the closure of HMRC offices and publication of beneficial ownership of Scottish Limited Partnerships, other companies and trusts. 


These proposals, across the political parties, indicate that the UK corporate tax landscape will continue to change after the election, whatever the results.  

Whether we have a Conservative or Labour government on 13 December or a hung parliament, there will be a continued focus on all aspects of corporate tax policy: revenue, fairness and efficacy.
