Understanding the Effective Tax Rate for Income between £100,000 and £125,140

When you're eyeing that £100,000 salary mark, it's easy to feel pretty good about your financial achievements. But hold on! You might be hit with a surprise if you don’t fully grasp how the UK's income tax system works, especially how it slams down on incomes between £100,000 and £125,140. Let's get into the nitty-gritty of effective tax rates and clarifying that seemingly simple answer choice can often be misleading.

What’s This Personal Allowance All About?

You know what? The first thing you need to understand is that everyone in the UK has a personal allowance—a tax-free threshold, so to speak. For the tax year 2023, this allowance is £12,570, which means if your income is below this level, you won’t pay any income tax at all! Sounds great, right?

However, here comes the kicker. For incomes above £100,000, your personal allowance starts to diminish. Specifically, for every £2 you earn over that £100,000 threshold, £1 of your allowance disappears. So, if you earn £105,000, your allowance gets slashed, and effectively, you pay more tax on that extra income.

Crunching the Numbers

Let’s take a closer look at the income tax brackets.

1. Basic Rate (20%): This applies to income over £12,570 and up to £50,270.
2. Higher Rate (40%): This is for income over £50,270 and up to £150,000.

Now, here’s the breakdown. If you earn £100,000, fantastic—you have the full personal allowance. But as soon as you hit that £100,001 mark, the tax implications shift drastically. Your effective tax rate climbs because not only are you paying the higher rate on the income above £50,270, but you're also losing out on your personal allowance.

By the time you reach £125,140, your allowance is entirely wiped out. So, for every extra pound you earn above that threshold, you're facing a slew of taxes across various brackets.

The Effective Tax Rate

So, what does this all mean for your effective tax rate? Let’s calculate it for income from £100,000 to £125,140.

• At £100,000, you’re just shy of a 40% marginal rate since your personal allowance is intact.
• But as you earn towards £125,140, the withdrawal of your personal allowance claims its toll. After crunching the numbers—taking into account how the personal allowance vanishes—you end up paying a staggering effective tax rate of 60% on the income ranging from £100,000 to £125,140!

Isn't that a punch in the gut? Think of it as climbing a mountain—every step feels worthwhile until those hidden pitfalls turn up the heat under your feet.
