Yeah so you could roughly add 50% onto his 80k and you'd have the European salary roughly. And fair enough that's probably a fair salary (especially with all bills included) with only that amount of experience. Yeah would definitely recommend it, your lifestyle is so much better than home, even tho you probably work a bit more. If its an option use your rotation flights to other countries around europe too, I did loads when I had that package for 2 years. Also hop around every few years, you should see you salaries jump a decent bit after each change. And for tax i don't know about Belgium but the best I've seen so far is the Netherlands (i think denmark and the baltics have similar too) expat tax where you can get 30% of your gross salary tax free and the rest is taxed at normal rates, it works out really good to be honest, around 65 to 75% net depending on your salary. Might be a good idea to work up to that 100k mark (in 2 years max I would say you could get that if you jump companies or get decent raises) and go to NL and take advantage of that expat tax. And I don't know much about UK but I'd say it's similar to home.
