Comparison of AI incident reporting deadlines: Australia, UK, Singapore vs. EU and US

AI&GPP compares reporting requirements for AI incidents in Australia, the UK, Singapore, the EU, and the US based on original documents from each country, noting that only the EU AI Act and the US GSA's LLM contract clauses specify hard deadlines for reporting to the government. Article 73 of the EU AI Act requires providers of high-risk systems to report serious incidents within 15 days at the latest, 2 days for widespread infringement or critical infrastructure disruption, and 10 days for fatalities; GSA clause 552.239-7001 requires notification within 72 hours with daily updates, and logs retained for at least 90 days. Australia has no specific AI reporting obligation yet; a rapid review launched on September 24 will provide recommendations, and Labor hopes to legislate by the end of 2026; the UK has no reporting obligation for developers, and AISI tightened evaluation safety controls on October 1. Singapore stated on October 6 that it does not require pre-deployment government access to frontier models, preferring to collaborate with developers.
