What is crossborder taxation?
Crossborder taxation, also called cross-border taxation, concerns income, assets or business activities connected to more than one country. It brings together tax residence, each country's reporting rules and the relevant double-taxation agreement, including the conditions for a foreign tax credit or exemption.
Can one team coordinate my German and foreign tax returns?
German and foreign returns should tell a consistent story about residence, income and tax paid. TWO.TAX reviews both sides together, identifies the reporting required in each country and applies the relevant treaty provisions. The countries, returns, advice and fee are confirmed in writing before work begins.
