As I expect to spend more than 183 days in Thailand 2025, I will become a tax resident there. I have therefore been able to agree a ‘Freistellung des Arbeitslohns vom Steuerabzug’ with my employer's tax office.
There is a form for this, simply called
"Antrag für unbeschränkt einkommensteuerpflichtige Arbeitnehmer auf Erteilung einer Bescheinigung über die Freistellung des Arbeitslohns vom Steuerabzug auf Grund eines Abkommens zur Vermeidung der Doppelbesteuerung"
As I have given up my place of residence in Germany, I will be subject to unlimited income tax for the last time in 2025, the year of my departure.
