Income Tax Disclosure [Abstract] |
Income Taxes | 13. Income Taxes We are subject to taxes for earnings generated in multiple jurisdictions, both inside and outside of the United States and our tax expense is primarily affected by unrecognized tax benefits in Denmark due to the full valuation allowance. We recorded expense for income taxes of $0.1 million and $0.4 million during the three months ended June 30, 2025 and 2024, respectively. We recorded expense for income taxes of $0.3 million and $0.8 million during the six months ended June 30, 2025 and 2024, respectively. We continue to maintain a full valuation allowance against all of our deferred tax assets in IO Biotech ApS, IO Bio US, Inc., a wholly-owned subsidiary of IO Biotech ApS that was incorporated in Delaware in May 2021, and IO Biotech, Inc. We have evaluated the positive and negative evidence involving our ability to realize our deferred tax assets. We have considered our history of cumulative net losses incurred since inception and our lack of any commercial products. We have concluded that it is more likely than not that we will not realize the benefits of our deferred tax assets in IO Biotech ApS, IO Bio US, Inc. and IO Biotech, Inc. We reevaluate the positive and negative evidence at each reporting period.
