Thank you very much.
Yes, UK tax is 40%, Pensions (like EPF 12.5%), and 8% national insurance (a bit like insurance premium, it is a form of tax).
Though job is more structured and secure. You won't get paid extra even if you work more or do more.

Council tax (a bit like Cukai Tanah) is about 20% of mortgage payment.

When gross income is between £100k to £125k, the effective tax rate is 60%, because we lose tax free allowance.

Okay to live a comfortable and stable life here, but very hard to accumulate wealth
