Neither House of Parliament sits again until next week. But with the Budget looming large on 28 October, we couldn’t resist a newsletter before the end of the conference recess.
There is always a fair amount of speculation ahead of a Budget, which impacts the behaviour of entrepreneurs well before the Chancellor utters a word. In a new report, Tax Policy Associates estimates that around £45 billion of gains were brought forward ahead of the October 2024 Budget, helping push 2024–25 taxable gains to a record £127 billion, 82% above the year before.
That might sound like a windfall for the Treasury. But those gains would otherwise have been realised over the following years and taxed at 24%; instead they were taxed at 20%, at an estimated cost of £1.4 billion to £2.4 billion. Dan Neidle, founder of Tax Policy Associates, expects the same happened before the 2025 Budget, and that it is happening again now. Nor is the instability new. Over successive governments, the headline capital gains tax rate has been raised, cut, raised again, and split into multiple sub-rates.
Research has found that Brexit uncertainty reduced business investment. More broadly, the academic literature shows that periods of high policy uncertainty coincide with lower business formation, investment and innovation.
After the 2025 Budget, the then Chancellor told the Treasury Committee there had been too much speculation and too many leaks, much of it inaccurate and very damaging. A leak inquiry followed.
Leaks aren’t the only problem, though. Newspapers, think tanks, business and lobby groups can fall into the habit of driving speculation. Sometimes it’s to head off changes they oppose. But sometimes it’s because taking credit for stopping a measure is a way to demonstrate influence, even when the measure was never really on the table.
This is familiar ground for the APPG. Back in 2018, our report on Tax Reform included cross-party forewords from Liam Byrne MP (Labour), then Chair of the APPG for Entrepreneurship, and Colin Clark MP (Conservative), who wrote that the Treasury and HMRC must ensure policy “has longevity”. The report found uncertainty over the Annual Investment Allowance (AIA) made it hard for firms to plan investments spanning three to four years. Since then, the 2022 Autumn Statement set the AIA at £1 million permanently, full expensing was made permanent in 2023, and both were confirmed in the 2024 Corporate Tax Roadmap.
In 2023, our APPG report Funding to Flourish argued that uncertainty about the future of the Enterprise Investment Scheme (EIS) and Venture Capital Trusts (VCTs) was already having a negative impact, because founders couldn’t plan fundraising rounds without knowing whether the schemes would survive their 2025 sunset clause. The report was launched in the Lords with Lord Leigh and the then Shadow Business Minister, Bill Esterson. The 2023 Autumn Statement extended both schemes to 6 April 2035, with support from both sides of the House, giving entrepreneurs and investors certainty about their future.
More recently, founders at our evidence session on R&D tax relief described years of near-constant change creating a chilling effect on legitimate claims. Unlike the AIA and EIS/VCTs, R&D relief has had no lasting commitment to stability in its rules. As the cases above show, stability commitments can be delivered and kept across governments.
Governments of all hues have used roadmaps to reduce speculation. Examples include the Coalition’s 2010 Corporate Tax Road Map, the 2016 Business Tax Road Map and the Corporate Tax Roadmap 2024. Their record is mixed, but each was an attempt to give business a clearer view of the years ahead.
In 2017, Better Budgets, a report by the Chartered Institute of Taxation, the Institute for Government and the Institute for Fiscal Studies, argued for one main fiscal event a year and a more open process. Some of its authors have since said tax policy making has gone backwards.
No government will tie its hands on every tax, but there is no reason Chancellors can’t commit to stability on most business taxes for the length of a Parliament, and rule out ideas they have no intention of adopting.
Whichever Chancellor manages to quell business uncertainty, now or in future, will find entrepreneurs ready to invest, hire and build the growth every party says it wants.
