I know I'm allowed to work in the UK for a maximum of 30 days per UK tax year and if exceeded this I have to do a 'local ties' quiz ie Do you own a house in uk ? , can you live in it ? , family in uk ? Etc

If I was to break the 30 days rule and after test it was deemed to still be a max of 30 days , let's say I worked in uk for 40 days in tax year 2016 to 2017.
What would be consequences be ?
1 - I would pay uk tax for earnings in those extra 10 days ?
2 - I would pay uk tax for earnings on all 40 days ?
3 - pay uk tax for all days worked in 2016-2017 regardless of if I was in uk or ch ie say 150 days in ch and 40 days in uk ?
4 - Be locked up in the Tower of London

Any help appreciated.

Thanks

I think it's door number 2 - all earnings but it depends on other things as well - have you exceeded your UK earnings threshold for that tax year? Do you work abroad? HMRC are interested in your worldwide earnings if you are in the UK long enough (depending on the criteria for your personal circumstances). It can be as little as 16 days if you're employed only part time in a different country.


I'd bite the bullet and call HMRC if I'm honest. Or get yourself a good UK tax person. They may also tell you to phone HMRC and then bill you for a consultation. There are also dual tax agreements in place between the UK and CH.

Employed full time in Switzerland.
Earnings over the 40 days exceeding tax threshold in uk of err £11,000 I think.
Then I guess it would be taxed at 20%.

I have a choice at the moment ;
Work in ch for a month post giving up apartment after 3 years and stay in hotel or work from uk office for month (20 days).
Between 20 days and start of uk tax year I would have already worked in uk for 10 days ....
So plan is finish employment via Swiss employer at end of October.
Register as resident in uk again at end of October and thus split tax year.
Apartment lease ends at end of September.
Option 1 - Stay in CH and find a hotel for a month.
Option 2 - Work in uk for final month (from uk office or home) and break tax rules.

Trying to figure best option ��

Seriously - phone HMRC. It's never worth trying to "break" a tax rule. Possible worst case, on that scenario, they're going to "get" you for 10 days and you'll probably be below threshold anyway. I wouldn't think it was worth it, IMO. You may just have to do your own tax return for a year. Seek proper tax advice, is my advice. Don't guess! Or ask strangers to guess!


Death and Taxes, right?

Yes I agree . I will take the pain like a man and phone the HMRC.

I phoned them recently and got myself in a proper tizzy beforehand. They couldn't have been nicer, clearer or more helpful. Seriously. They don't want to make you cry, they just want you to be straight with them, I reckon.


Good luck! (And with the move back to the UK).

Thanks

if you return to UK and work the final month there, you have no longer "left the UK for employment", even if your contract in Switzerland is still running....you will (if following the rules) need to declare residency from start of October.

No idea what proof of return date HMRC requires these days, but in helping expats when I worked in the UK 6 years ago, they sometimes asked for the removals invoice as proof that someone left the UK.
