I'm thinking about taking a job in Germany, and for the purpose of salary negotiation I'm trying to estimate my net income using this calculator. What complicates matters is that my family won't be able to move to Germany right away, so I will be going to Germany for a week alone, spending weekends with my family in France.
Will I be able to pay my taxes as class III, IV or V, and list my kid as a dependant on the tax return form? If not, what extra conditions should be fulfilled? E.g. does my family have to live in Germany too, or do I have to spend X days per week with them (presumably working remotely)? Does anything changes if my wife also has an income in France?
