This profile assumes a small software or IT company that relies on cloud infrastructure, so it adds obligations aimed at digital and cloud-dependent businesses - the AI Act's transparency duties, NIS2 for critical digital infrastructure, cybersecurity requirements for software products - alongside the standard tax and reporting calendar. Your actual exposure depends on whether you build AI systems, handle personal data at scale, or count as an essential or important entity under NIS2, so treat this as a starting shortlist rather than a final answer.
