| Income Tax Disclosure [Abstract] | |
| Income taxes | Income taxes Income tax expense is recognized at an amount determined by multiplying the net income (loss) before income taxes for the interim reporting period by the Company’s estimated annual effective tax rate, adjusted for the tax effect of certain items recognized in full in the interim period. As such, the effective tax rate in the condensed consolidated financial statements may differ from the Company’s estimate of the effective tax rate for the Company’s consolidated financial statements for the year ending December 31, 2025. The Company’s consolidated estimated effective tax rate for the three months ended March 31, 2025 was 17.4%. During the three months ended March 31, 2025, the Company recorded a tax charge of $1.1 million, compared to a tax charge for the three months ended March 31, 2024 of $0.4 million. The Company benefits from the U.K. large company Research & Development Expenditure Credit ("RDEC") regime which can generate a cash rebate of up to 15% of qualifying research and development expenditures incurred after April 1, 2023. Tax credits receivable under the RDEC regime are recorded "above the line" as a reduction from research and development expenses. For the three months ended March 31, 2025, the Company excluded the United Kingdom from the calculation of the annual estimated tax rate as the Company anticipates an ordinary loss in this jurisdiction for which no tax benefit can be recognized. A net deferred tax asset of $14.4 million has been recognized as of March 31, 2025 (December 31, 2024: $14.8 million) primarily representing research and development credits and share-based compensation for one of the Company’s U.S. subsidiaries, Immunocore LLC, following an annual assessment, or periodically as required, of all available and applicable information, including its forecasts of costs and future profitability and the resulting ability to reverse the recognized deferred tax assets over a short period of time. During the three months ended March 31, 2025, the Company received U.K. tax credits of $6.8 million relating to research and development expenditure in the year ended December 31, 2023.
