Ce qu'une entreprise SaaS ou informatique doit déposer en Pologne en 2026
Ce profil suppose une petite entreprise de logiciels ou informatique qui dépend d'une infrastructure cloud : il ajoute donc, en plus du calendrier fiscal et déclaratif habituel, les obligations visant les entreprises numériques et dépendantes du cloud - les obligations de transparence de l'AI Act, NIS2 pour les infrastructures numériques critiques, les exigences de cybersécurité pour les produits logiciels. Votre exposition réelle dépend du fait que vous développiez ou non des systèmes d'IA, que vous traitiez des données à caractère personnel à grande échelle, ou que vous soyez une entité essentielle ou importante au sens de NIS2 : considérez donc cette liste comme un point de départ plutôt qu'une réponse définitive.
Cette page part d'un profil de départ précis : entreprise SaaS ou informatique, en Pologne. C'est un point de départ, pas un conseil personnalisé - vos obligations réelles dépendent de votre secteur exact, de votre chiffre d'affaires et de votre mode de fonctionnement.
