Corporate residence / effective management
Article 4(3) treats a dual-resident non-individual as resident only where its place of effective management is situated. If that cannot be determined, the competent authorities seek a mutual agreement; without one, treaty benefits are unavailable. This matters directly where a Ukrainian company is effectively managed from Germany.
Permanent establishment
Article 5 includes fixed-place PE, a place of management, branch and office, a twelve-month construction threshold, a dependent-agent rule and anti-fragmentation logic. The country of incorporation alone therefore does not answer the operating-nexus question.
Associated enterprises / transfer pricing
Article 9 applies the arm’s-length principle to associated enterprises and provides for corresponding adjustment. For a Ukrainian OpCo + German GmbH model, functions, assets, risks, contracts and remuneration need to reconcile.
Technical services
The Protocol to Article 7 expressly treats payments for technical services, including engineering, consultancy and supervisory services, as Business Profits. That does not itself answer the tax outcome: residence, PE, domestic law, classification and the actual service model still need to be tested.
Change of residence and exit-tax coordination
Article 13(6) does not create an exit tax. It coordinates consequences where an individual, after at least five years of residence in one State, becomes resident in the other and the former State taxes shares on a deemed disposal: the new residence State then uses the value applied by the former State when calculating a later gain.
