It's nights at midnight, pass it by 1 day & there is no way in your situation you would be other than UK tax resident. It works for most people however with a wife & kids in the UK it would be difficult, unless they come to you some weekends etc.
With Covid lockdown this will catch out many people.
As the UK is not in Schengen, it's very easy for them to check the days at midnight when you are commuting to a Schengen country. HMRC's fines plus interest are so extortionate that it's not worth being economical with the truth.
A close connection & dual UK/CH resident had been under investigation by HMRC for 20 years, he paid them in excess of 10 million before the investigation started, then during the investigation went on tax strike by donating in excess of 100% of earnings to charity. HMRC eventually settled in 2019 refunding in excess of £750,000 overpaid tax plus interest. If a year is under investigation it's not closed so you can re allocate any loss relief against years with the highest tax liability. HMRC employees tend to be left wing & jealous of successful people, HMRC would have collected an additional 5 million had they not got nasty.
What does it mean that you have to tell hmrc if you move abroad ??
Can you do that by ticking the box of non resident tax on your self assessment? Or is it some other way?
Normally you advise them by form or mail when you are 'permanently' leave CH, that would imply a full time job lasting at least 1 UK tax year.
They would probably ask for further information if giving a UK address & ticking non resident as the 2 don't match what they would expect.
HMRC have had current up to date addresses for me since leaving the UK in 1994. My last UK tax return was 1994/5. I did however filled in a DTA in in 2017 & 2018 to get a NT tax code for UK pensions & I made NI contributions in over 15 of those years since leaving the UK

Best to be upfront with HMRC.
As FMF alluded to, please also look at paying voluntary Class 3 NI contributions. There are a number of threads covering the topic, or just ask.
Don’t fill in this form if:
you normally live in the UK and you’re going abroad for short periods, for example on holiday or a business trip
you’ve filled in, or been asked to fill in, a Self Assessment tax return for the tax year that you leave the UK
So if you fill ina self assessment which most people Do who have rental income you do not need to tell them ... was worried about this as accountant in Uk is normally on top of stuff
With luck class 2 can be paid at about 1/4 of the cost of class 3, I paid Class 3 until I had 30 years UK contributions which became the max required (reduced from 40 years). They then changed the rules to 35 years & I was able to buy those years as class 2 as the rules changed about 15 years ago.
Maybe it's Class2 then. One of them is the full monty, and one only basically covery the pension.
Maybe I should start a new thread but for those ex contractors who are still taking a 10k salary from their Uk limited and therefore pay just enough for the ni contributions
Do they need to top up class 2 or class 3 Uk pension?
Does your pillar 1 contribution count towards the Uk pension for those that leave before retirement
It means that it facilitates tax matters, including refunds, for example if you're on PAYE based upon a full tax year you might have paid too much tax. If you're not concerned about that or normally fill in a tax return then it's not necessary as you can make a declaration there. Obviously telling them your new address is useful if they ever need to get in contact with you.
I've never filled in any special form and have had tax returns delivered to UK addresses without ever having had any problem. I do file the non-resident tax return every year which you can't do using the HMRC's own online forms even though the result is always the same as filing a resident tax return.
Nope they are cleverer than that, they take a salary around £8500 so get credits for NI without actually paying any.
Pillar 1 is for a Swiss pension in addition to UK pension.
