Unique Taxation Dissertation Topics With Research Aims
Topic 1: Impact of Artificial Intelligence on Taxpayer Risk Profiling and Audit Accuracy
Research Aim: This study aims to explore how tax authorities are using artificial intelligence to identify risky taxpayers more accurately. It will look at whether AI makes audits fairer, faster, and more efficient, and how it affects taxpayers’ trust in the system, especially small businesses and individuals.
Topic 2: Role of Climate-Linked Tax Policies in Driving Green Investment in the Private Sector
Research Aim: This research will investigate how green taxes, like carbon taxes or tax breaks for eco-projects, influence private companies to invest in sustainable technologies. It will measure the real-world impact of these policies and explore whether they genuinely help businesses go green or just shift costs.
Topic 3: Evaluation of Taxation Equity in Digital Labour Platforms Across Different Income Groups
Research Aim: This study will examine how fair current tax systems are for people earning through digital platforms like ride-sharing or freelancing. It will analyse whether low-income workers are taxed more heavily or unfairly compared to higher earners, and how policy can be adjusted to ensure fairer outcomes.
Topic 4: Qualified Domestic Minimum Top-Up Taxes and Revenue Retention in Low-Tax Investment Hubs
Research Aim: This study examines why low-tax jurisdictions introduce domestic minimum top-up taxes under the global minimum tax rules and how much revenue they expect to retain.
Legislative analysis will be combined with published country-by-country reporting statistics to compare the design choices of investment hubs such as Ireland, Singapore and Switzerland.
Topic 5: Making Tax Digital for Income Tax: Compliance Costs and Reporting Accuracy Among UK Sole Traders and Landlords
Research Aim: This research assesses how quarterly digital reporting under Making Tax Digital for Income Tax affects compliance costs, record-keeping and reporting accuracy for UK sole traders and landlords.
A survey of affected taxpayers will be combined with interviews with the accountants and bookkeepers who support them.
Topic 6: VAT on Private School Fees and Pupil Movement Between Independent and State Schools in England
Research Aim: This study investigates how the application of VAT to private school fees has affected fee levels, pupil numbers and transfers to state schools in England.
It will analyse published school census and fee data and interview school bursars about how much of the tax has been passed on to parents.
Topic 7: Carbon Border Taxes in the UK and European Union: Design Differences and Compliance Costs for Importers
Research Aim: This study compares the design of the UK and European Union carbon border adjustment mechanisms and the compliance costs they create for importers of steel, cement and aluminium.
A comparison of the two sets of rules will be combined with interviews with importers, customs agents and tax advisers about registration, emissions data and pricing decisions.
Topic 8: Inheritance Tax Relief Reform and Succession Planning on UK Family Farms
Research Aim: This research explores how changes to agricultural and business property relief influence succession planning, lifetime gifting and investment on UK family farms.
Semi-structured interviews with farm owners, land agents and tax advisers will be combined with analysis of published farm business income data.

Frequently Asked Questions
Start with a tax rule that has changed, then ask who responds to it and how. Budget documents, tax authority consultations and reports from the Institute for Fiscal Studies show where evidence is thin.
Journals such as the British Tax Review and Fiscal Studies help you check what has already been answered. Choose one tax, one group of taxpayers and one country.
Popular themes include corporate tax and investment, personal tax and work incentives, VAT and indirect taxes, international tax and the global minimum tax, tax compliance and digital tax administration, environmental taxes, and tax policy and inequality.
Taxation in emerging economies is also widely studied, especially consumption tax reform and the taxation of digital services.
Follow your degree. Law students usually analyse legislation and case law, accounting students examine reporting, compliance and practice, and economics students measure how taxpayers respond to a change.
The same topic can be framed in each way. A study of the global minimum tax could analyse the rules, interview tax directors or estimate revenue effects.
HMRC publishes statistics on receipts, reliefs and the tax gap. The OECD publishes revenue and corporate tax statistics for comparing countries, and company annual reports disclose effective tax rates.
For behaviour and attitudes, run a survey or interview taxpayers and advisers. Tax is a sensitive subject, so guarantee anonymity and avoid asking participants to admit non-compliance directly.
Build the topic around a principle or a behavioural response, not a rate or threshold. ’How do owner-managers respond to dividend tax changes?’ stays valid after the next Budget, while a question about one rate does not.
State in your methodology the date at which the law is described, and treat later changes as context in your discussion chapter.
