It depends where in Switzerland you work. If working in Basel and some border cantons for example you pay tax in France if you live in France whether you like it or not, depending on family situation it's not always a big disadvantage.
I too am a Frontalier, commuting daily and paying my income tax in Zürich. Even if you work in Zürich, Geneva or similar canton, you will still have to fill in the Income tax form next year if you are classed as resident this year. Also any almost all other world-wide income you have that's not Swiss wages, e.g Pension, savings interest, UK income from rent or whatever will need to be declared and will have a tax levied.
You will also have the choice of joining the French health care system, usually within 3 months of deciding to reside in France. If you don't expect to reside in France long term I wouldn't worry but there are moves afoot to make health care decisions long term and binding for all frontaliers.
Many banks will give you up to a year free banking with luck.
Good Luck
