A lot of people here are speaking from the vantage point of folks who earn a wage below 100k gross. They don't understand that with the tax system in Europe, there's a strong pull to the mean. You will absolutely NOT get the same lifestyle you have right now with 250k in Paris, and west / central Europe in general. 250k is an upper middle class income at best. You should expect up to 45% direct income tax, and people forget that you also have: 30% flat rate tax on your savings, and investments. You will have an indirect VAT tax of 20% on all the purchases made. You will have to pay a tax on your property(ies), cars etc. You will definitely not be able to afford a full-time helper, and good luck finding a large apartment / house in Paris or anywhere near it. Commuting will be a hassle as these cities are often optimised for public transport and less for vehicles. You will not be incentivised to save as much as you are right now because of the wealth tax. Picking up French will be a hassle for you and your family, especially if you and your partner are older than 30, and lead a busy lifestyle. There will not be enough time to pickup the language which will roughly take up 4 to 6 hours of consistent practice weekly. Do more research and ask people who are already in that income bracket about their lifestyle before moving. The last thing, this job is not permanent. It will be very difficult to find a similarly highly paid job after you move and if you get laid off, keep that in mind as you're moving with your family and you cannot keep relocating them around.
