In the UK, I calculated I paid roughly 22% on a similar employee salary by putting enough money in pension contributions (+ employer match and government match).
I also have a limited company where I do occasional work (without having to increase my income taxed at 40%) and that I use to draw dividends from (up to free allowance) yearly and get some other advantages, which was a decent way to get extra untaxed income. These days the allowance is 2k so there is not much to get.
The disadvantage of using a pension is that I won't get that money until I'm 60 (and they keep increasing the age where you can withdraw money). I'm kinda forced to do that and maximise
I'd rather invest the money in buy-to-lets than the weird ETF a pension is, but then I would lose 40% of my money to the government.
Being employed in the UK is not very convenient over 50-70k (and it becomes especially painful at 100-120). You are always better as a contractor outside of IR35 with your own limited company, unless some of the benefits make it worth it (eg. long paid m/paternity leave, stock options you really care about).
Unfortunately being outside IR35 is getting more complicated, corporate tax rate is increasing and buy-to-lets lost some of the tax advantages they had.
Overall if I had to pick a country with bad weather to make money in, I'd go with Switzerland instead of the UK.
