I don’t have an answer but I have the feeling that taxes might play an important role
Personally, I grew up in Italy next to the Swiss border. After working for 3 years in Italy, I have been transferred to the Ticino branch of the company and I became a cross-border worker (I was still living at my parents). Then I moved to Geneva but lived in France, then finally moved to Geneva.
For me, moving here was the right choice for several personal/family reasons and I love where I am now… from a financial point of view, it was not the cheapest option.
But… some random ideas to take into consideration:
if you work in Geneva and have ~90% of your income here (as far as I remember), you have the “quasi-resident” status and you are taxed just in Geneva (they send back a part to France, but you basically pay the same amount as if you were living in GE)
Already if you change job and go to work in Vaud, it’s a different story. As far as I know, you will be taxed in France and the “barèmes” % are not at all the same.
Same if you live live in Alsace and work in Basel area, or if you live in Germany and work in Zurich etc.
Apparently it might be expensive.
What if you have significant investments / properties / returns, and you have less than 90% income from GE? Will you be taxed completely in France at that point? Idk but I would check before
Ticino and Italy had an agreement similar to Geneva with France: at the time I was paying taxes just in CH… so basically my gross income was the same than Italy, but the net was higher.
Now Italy would like to collect all the taxes and do like Germany and France (with the exception of Geneva). Who knows if and when it will happen? It might change the plans.
France would like to tax the home office work for people employed in Geneva. They didn’t find an agreement yet, and they might never find it
For the moment, they are just extending COVID exceptions for work-from-home… but our company already told to border-workers (~50% of the workforce) that without an agreement, they will have to come back 100% at the office and they won’t be allowed to connect from home at all.
So, if you are used to flexibility and you can go pick up the kids at school at 4PM, then connect again in the evening to send a couple of mails… it might be annoying.
Also, if they don’t find an agreement, border-workers will be less attactive for employers imho companies are shrinking their offices but they need to keep enough room for border-workers, while swiss-residents can work from home (in our case, we already closed 1 floor out of two in our building, after COVID).
In CH, I can work from home and when I go to the office I have just 2km of walk.
If you live in France, you might need to take the car (unless you are not in the expensive Saint Genis or Ferney-Voltaire area).
Also, border-workers can’t have the company car anymore unless the company is paying VAT on it in France (for sure no company wants to do that).
I know most of people don’t have this first-world-problem, but for me it would be annoying… I use the car for customer visits, in Switzerland I can get a company car and use it as a personal vehicle as well. In France I would be obliged to switch to a car-allowance payment and lease a car compliant with the company policy.
- 3rd pillar taxes? It looks like border-workers can’t deduct anymore, I didn’t investigate much but some of my colleagues were complaining.
And what about when you will withdraw it? I have no clue but I would try to understand before moving
But it depends a lot on your personal situation, I think… kind of job, if you would like to keep working from home, how much do you earn and spend in Switzerland, potentials savings in FR/DE/IT, how you would be taxed, what about the school for the daughter, healthcare, etc
For sure if you are Swiss now, it’s easier to find a job even if you live in France and you won’t need any work permit… but other factors might play a role.
It might also depends on your FIRE goals. If moving to France would really make a difference, why not…
In my case, I’m still too far so for the moment, I prefer to stay in Switzerland and have the flexibility to work from home, to move to another Canton, to be employed in another Canton (with the same taxes), to have less commuting etc.
Maybe at some point I will be closer to FIRE, it will be worth tax-wise and I won’t stand my job anymore then I’ll go for it. But not so soon… (even though I enjoyed France and the village where I lived)
(all the ideas are “as far as I know” / “as far as I remember”, please forgive me if it’s not accurate)
