Intern - Behavioural Insights (Taxpayer eXperience & Strategy)

Want to use behavioural science to solve real-world public service challenges? We are looking for a curious, analytical and purpose-driven Behavioural Insights Intern to join the Inland Revenue Authority of Singapore (IRAS). In this role, you will apply behavioural science to tax administration — uncovering why people behave the way they do through research, and testing what works through randomised controlled trials (RCTs) and A/B testing. You will contribute to 1 to 2 behavioural science and/or design projects that aim to make tax compliance intuitive and taxpayer-centric. • Design and run trials: Support A/B tests and randomised controlled trials (RCTs) to find out what truly works. • Conduct user research: Support surveys, interviews and Focus Group Discussions (FGDs) to understand taxpayers’ needs, behaviours and pain points. • Analyse evidence: Clean datasets, run statistical analyses and evaluate trial results to measure the impact of behavioural interventions. • Turn insights into action: Combine qualitative stories with quantitative data to develop practical recommendations for better service delivery. You will be mentored by a supervisor, work closely with project leads, and receive real-time feedback as you build hands-on experience in applying behavioural insights within a public service context. • Students in Psychology, Economics, Statistics or related fields • Strong foundation in experimental design and results analysis, including randomised controlled trials and/or A/B testing • Experience or interest in quantitative and/or qualitative research • Strong presentation, writing and verbal communication skills • Good self-management skills, with the ability to work independently and meet project deadlines Internship Duration: 6 to 12 months, with intake from August 2026 onwards.
