Tax implications of almost earning £100k - TaxScouts

Do you have an income of nearly £100,000 a year? If so, there’s some important stuff to know before you reach that luxury salary bracket. 

If you didn’t know already, there are some big differences between earning a five-figure income versus a six-figure one. Knowing what these differences are is crucial when it comes to taxes. 

So, if you plan on earning more than £100,000 in the future, here’s everything you need to know ahead of time about tax. 

After all, preparation is key, right? 😉

I earn nearly £100k, how much will I be taxed?

Let’s start by looking at what you’ll pay in tax on your current income.

For the 2024/25 tax year, if you earn more than £50,270, but less than £125,140, you’ll pay income tax at a higher rate – this is what’s known as the 40% tax bracket.

The 40% tax bracket explained

The basic income tax rate is currently 20%. This is the percentage you’ll be taxed on any income you make between £12,570 and £50,270.

As we explained above, this tax rate increases to 40% for earnings above £50,270 and stops at £125,140. 

Still confused? Don’t be – we’ll explain in further detail 👇

Do I get any allowances?


If you earn under £100k you’ll still benefit from the Personal Allowance. This is the amount of tax-free income you’re entitled to receive each year, which is currently £12,570 for the 2024/25 tax year. But you can only claim this in full if you earn less than £100,000.

What about National Insurance?

Your National Insurance payments will be higher if you are in the 40% tax bracket. 


Well, the basic National Insurance rate for Class 1 payments (which you pay if you’re employed) is 8% for anyone who earns more than £242 per week. 

If you’re nearly earning £100K, you’re in the higher rate tax bracket – and this means you’ll have to pay 2% on your earnings over £967 per week.

So what happens if I start earning more than £100k?

Firstly, congrats on your six-figure salary! 

Whether it was for a promotion, a big commission on your sales, or a yearly bonus as a reward for your hard work, it should be a reason to celebrate.

And it would be if you weren’t now paying a higher tax rate than anyone else in the UK! 😳

Wait, what!? 😨

Yes, sorry to be the bearer of bad news, but once you start earning more than £100,000 everything around tax changes.

Remember your Personal Allowance? That £12,570 chunk of income that HMRC lets you have tax-free? Well, that is reduced by £1 for every £2 you earn over £100,000. And once your income reaches £125,140, your Personal Allowance drops to £0. 

In other words, your tax rate for any income you make between £100,000 and £125,140 essentially becomes 60% – yikes!

Do I need to report my earnings to HMRC if I start earning £100k+?

No, not yet!

Thought tax returns were just for the self-employed? Well, you’re wrong! 

When you earn over £100k, you’ll be classed as a high earner in the eyes of HMRC. Until recently, this meant that you needed to register for Self Assessment and complete a tax return so that HRMC could check that you were being taxed the correct amount.

But, on April 6th 2023, things changed.

Anyone earning over £100K from the 2023/24 tax year (6th April 2023 – 5th April 2024) no longer needs to file a tax return unless you need to file a tax return for another reason (e.g. property, CGT, self-employed). In 2023/24, the PAYE threshold to file was increased to £150,000+ per year. But from the 2024/25 tax year, the need for PAYE high earners to file at all was abolished.


Well, kind of. If you’re a high earner with an income over £100,000, it’s still worth checking in with HMRC that you’re on the correct tax code. If you’re not, they’ll collect any tax underpayments from your salary.

Are you a high earner that needs tax help?

Paying UK tax as a high earner might sound pretty confusing – especially if you’ve only just started earning more than £100k – but it doesn’t have to be complicated at all!
