An Excess Profits Tax 

Michael P. Devereux

The incoming Labour government intends to publish a Roadmap for Business Taxation for the next parliament. In this blog and in a recent paper, Michael Devereux discusses the possibility of introducing a new tax on excess profit earned by businesses that sell in the UK. The tax would be less distortive than existing taxes on business income and may therefore represent a way to raise revenue that is consistent with the government objective of new economic growth.

Tax Audits: Long-run Impacts on Intentional and Unintentional Non-Compliance

Business tax paper of the month - July 2024

Tobias Christensen (University of Copenhagen)

Tax audits are a key tool to secure a high level of tax compliance. In this blog and in a recent paper, the author shows that the impact of audits varies significantly with taxpayers’ intentions to comply. Audits raise future compliance significantly among taxpayers who inadvertently make mistakes due to confusion or inattention; however, those who deliberately evade taxes do not increase compliance after audits. The findings have implications for the optimal use of scarce resources in tax agencies.

The Transfer Pricing Directive - Round 2 for an EU ALP?

Richard Collier (Oxford University Centre for Business Taxation), 3 July 2024

The proposed Transfer Pricing Directive is intended to create more certainty for taxpayers, as well as reducing tax avoidance, litigation, double taxation and compliance costs. In this blog and in a recent paper, the author discusses whether these ambitions can realistically be met, and also whether the Directive would create a problematic schism between what would then be an EU version of the transfer pricing rules and the OECD’s Transfer Pricing Guidelines.

Spending Responses to News about Dividend Taxes

Business tax paper of the month - June 2024

Martin B. Holm (University of Oslo), Rustam Jamilov (All Souls College, Oxford), Marek Jasinski (Statistics Norway) and Plamen Nenov (Norges Bank), 17 June 2024

Dividend taxes affect the after-tax return to savings and therefore shape household decisions about saving vs spending. In this blog, the authors study how spending responded to a massive dividend tax reform in Norway that raised the dividend tax rate by 28 percentage points. While spending increased in response to news about the reform, it decreased at the time of the actual implementation. These findings have implications for the effect of interest rates on savings, which is key for a range of questions in economics and finance.

The Efficiency-Equity Tradeoff of the Corporate Income Tax

Business tax paper of the month – May 2024

Patrick Kennedy (UCLA, NBER, and JCT), 20 May 2024

The impact of corporate tax reforms is complex: reducing tax rates may boost investment, raise shareholders’ returns, and increase workers' earnings, but these benefits may be distributed unevenly throughout the economy. In this blog, the authors study these mechanisms in the context of the 2017 Tax Cuts and Jobs Act in the United States, and shed light on the trade-off between efficiency and equity facing policymakers when setting business tax policies.

Harnessing global financial transparency to improve tax enforcement in developing countries

Niels Johannesen (Oxford University Centre for Business Taxation), 9 April 2024 

Governments have developed a potentially powerful approach to enforcing taxes on offshore financial income and wealth: automatic information exchange across borders. In this column, and in a recent paper, the author discusses whether the approach is suitable for developing countries with limited administrative capacity and whether there exists a better alternative.
