Social contributions and most deductions are not modeled. A US citizen in Monaco owes US federal tax: $138K on $500K, $320K on $1M, $1.1M on $3M on the engine's floor. The foreign earned income exclusion covers a capped slice of salary and none of the investment income, so the model leaves it out.
Leaving the UK is tested, not declared. The date you break residence is tested under the statutory residence test. No exit tax as such. The temporary non residence rule taxes gains realized abroad on assets held before leaving, at 24% today, if you return within 5 years and had sole UK residence in 4 of the 7 tax years before leaving. After more than 5 years of non residence the rule no longer applies. Leaving the UK: the exit tax →
