It’s worth considering employer payroll taxes which might be different (though my memory from looking it up a while ago was that the payroll taxes weren’t so different). It’s also possible to have another effective 9% marginal tax from student ‘loans’ though that will go away after a while.
It's not normal to count payroll taxes as part of the employers tax, as that would also increase the gross salary above that which the employee considers their salary to be. E.g. nobody factors that in when comparing California salaries to the many US states with no payroll tax.
Even so, you need to get up towards 300k GBP/year to exceed 50% even with the payroll tax. And that assumes you're making zero pension contributions (as contributions are offset against your tax up to 40k gross/year)
With respect to student loans, sure, you can add that in but then you need to do that when comparing to the US salary levels in this thread too.
Payroll taxes matter to some extent when comparing employment in different tax regimes because they determine (some of) the total cost to the employer. They can also matter for contracting arrangements. Though the local job market probably matters more.
Yes, but the sub-thread here started with someone suggesting they'd be paying 50% tax, and when talking in terms of employees, it's not normal to include it. When including it, we're usually talking about total tax wedge rather than tax rate (e.g. see OECD Taxing Wages).
Even so, as noted, you'd not hit 50% even with payroll taxes at anywhere near the income levels stated. At the stated 100k GBP contracted salary, your "salary" including payroll tax would be 113,207 GBP, and your total tax wedge would be 41% (compared to 33% combined income tax and NI).
Fair point. I was mostly responding to the bit from the root comment about the comparison between countries and not their incorrect understanding of taxes in the U.K.
