The people working and paying taxes?

We're all working & paying taxes whether we earn £100k or not.

I agree it's unfair but don't imagine you are the only ones. What about the couple on £119k who still get full child benefit, while a single mum on £80k gets nothing.

Be careful what you wish for !

Women worked long and hard not to be a financial appendage of their husbands and now you want to reverse it?

The low paid parent (which is often the mother) already loses out in the current scenario.

They lose tgeir child benefit if the other parent earns over £60k (tapering to 80k)
They lose the childcare subsidy at £100k. Which can mean the childcare is more than their wage.

A whole family assessment is fairer for the lower paid parent.

With that logic people working and earning £1M and paying taxes should be entitled to free childcare? It's interesting that there's an argument here for universal free childcare irrespective of income, do you think other state benefits should be means tested or universal? I agree personal allowance shouldn't be removed at any threshold so tax tapers rather than creates a cliffe edge. You can contribute to a pension though to bring your gross under £100k and avoid the cliff edge.

Interesting - do you think schools and healthcare should be means tested too? As millionaires can currently get those free. To me, childcare is closer to those things than say universal credit.

Yes, I don't feel that makes a difference to my thoughts on that. It's only very recently that it became a thing.

But the cost of child care has never been so high. My 16 year olds nursery has more than doubled (was £27 a day is now £64). Where as national average wages have gone up by about a third in the same time frame. And this is relatively cheap for many areas.

Somersetbaker · 17/09/2026 08:27

I'll let you know if it's a problem when I get more than £100k a year. First world issue.

Melarus · 17/09/2026 08:26

Sure, it's unfair ... but on my mental tally of things that are unfair, illogical, undesirable, unjust and painful in the UK at the moment, it's pretty far down the list

It is the exact same principle when people reduce their hours because earning more would disproportionately reduce their benefits.

You’re brave. The fires of hell descended on me when I said exactly the same thing a few months ago.

Edited

It’s not though is it. The person reducing their hours to avoid excessive tax - and I think we can all agree that the tax man taking 67% of your earnings is excessive - is still standing on their own two feet. The person reducing their hours to increase their benefits is doing so to get more from the state. They are takers, not givers.

Cliff edge taxes like this are stupid. It really does incentivise people to not hit it especially those with children.

While it isn’t necessarily a bad thing for individuals to be stuffing their pensions, it can be that good for the economy as a whole because those individuals may well be going for very high pension contributions at the expense of paying for a cleaner for example or spending on meals out

And when these high earners, the disparity between wealthy pensioners (which yes they’ve paid for and will be taxed on) and the ordinary Jane and Jack will be even wider than it seems today.

Also if all the essential workers like say medics who earn highly go part time and a load beetle off to Dubai or Australia or whatever it’s no surprise we have shortages in key areas. There’s a big ripple effect from these cliff edges and I’d prefer more equality, plus perhaps fewer ways to reduce tax through things like salary sacrifice schemes. Just make things fairer for everyone!

We did exactly this. When our mortgage went up, we reviewed finances. It wasnt tax efficient for me to go full time, we saved more by cutting having a cleaner and reducing our holiday budget.

Tbh I am in this boat and while it is particularly crap if you get a bonus and lose most of it.... I can afford it.

At the end of the day a hell of a lot of money hits my bank account every month. More than I need. I can pay my way.

Basically this - and no - we have never earned more than £40k tops for either of our salaries.

The taxing of billionaires is the one that really needs looking at!

I agree. In general, I think there should be much more pragmatism and less ideology around benefits and how they are administered - which probably would mean more universal benefits.

I also think there should be broader tapering.

And- and this might be a separate point- I do also think there should be more state investment in high quality, heavily subsided childcare so no one is paying such extortionate childcare costs, and private nurseries are not being propped up by the tax system.

I agree re childcare. I think there should be:

  • state/non profit nurseries from age 2
  • a big program to encourage in home childminding for babies as its more important they have a single consistent caregiver.

I have long thought that if people could use state funded childcare hours to pay their own mum to care for their kids, a lot of the women who dont work in their 60s would suddenly become more economically productive in providing childcare for grandkids.

This, i went part time for years to avoid it but also then never went back full time even having gone through as it didnt feel worth it.

I went part time for other reasons, but once you are part time not many people go back to full time if they can help it. This is one of the main issue with incentivising people to go part time. It reduces tax take in the long term, not just e.g. while you need to get under £100k for childcare reasons.

MouseInTheWoodpile · 17/09/2026 08:13

At the lower end … increase the personal allowance but reintroduce the 10% rate.

I was going to write a reply about how it can be really tricky, but let's be honest £100K is still an awful lot of money for many people even after you take into consideration mortgages etc in the SE.

So what I will say instead is that the tax trap drives adverse behaviours and I know a number of people who either reduce their hours, change their jobs for a lower salary or pop more in their pension to avoid paying the additional tax. Means less to the tax man, less in the way of consumer spending. You have to be earning considerably more to off set the cliff edge and most career progression scales don't make it worth it - particularly for women who are often juggling caring responsibilities too. Increasingly it is a perverse incentive to earn/have higher take home pay.

Yes, I do think there needs to be some sort of household calculation.

Women worked long and hard not to be a financial appendage of their husbands and now you want to reverse it?

Fizbosshoes · 17/09/2026 08:10

MPs salaries are very close to 100k, I wonder if there will be more incentive to change things once they are....?

I don't agree with any cliff edge scenarios, or taxing over 50% morally. It's also discouraging people from earning and paying more taxes to the nation.

That said, the carers allowance cliff edge impacts the recipient far more, so should be the first priority for reform.

It doesn’t earn as much money if you take it away. If the government takes this cliff edge away the TAX TAKE INCREASES. It should do it immediately as a total no brainers. It could also increase the top rate of tax and the same time and people wouldn’t moan because the majority of people - and the government- would still be quids in.

And then start on the career cliff edge, and the child benefit cliff edge. Child benefit should be universal. It would be much simpler to manage and encourage people to earn more.

concertinacornflake · 17/09/2026 07:01

Govenments do a lot of tinkering that undermines principles. The Cameron/Osborne/Clegg changes were a low point.

Tax should be progressive without cliff edges.
Benefits can be universal or targeted. Important to recognise there is a lot of unnecessary cost in means testing - it costs a lot to administer.

I agree. In general, I think there should be much more pragmatism and less ideology around benefits and how they are administered - which probably would mean more universal benefits.

I also think there should be broader tapering.

I don’t think in the current circumstances that the country is in that people earning over £100k is or should be a priority

Cliff edges like that at 100 and over are bad for everyone. The government loses tax revenue when people reduce their hours or turn down additional work to keep their earnings below £100k - which many do. It is the exact same principle when people reduce their hours because earning more would disproportionately reduce their benefits. i appreciate the the two groups in very different financial positions, but that isn't the point.

The point is that tax and benefits changes behaviour, and not necessarily in a way that is beneficial to the country. It's not rocket science, but a well designed system should encourage people to work and earn more, not create perverse financial "incentives" to do less than they could.

My salary is pretty low, but I do actually agree. I think that no one should lose the first 12k or so tax free part.

It's only eroded away slowly as your pay rises over £100k, the loss of childcare seems a bit brutal, but I guess very few fall into the trap they just increase pension contributions to avoid it all.

It’s the Cliff edge Nature that’s unfair. There should be broader tapering to stop the all or nothing result rechildcare. It’s also insane to have a 62% marginal tax rate at exactly the same point as losing free childcare. We shouldn’t have any marginal tax rates over 50% at any income level. We need to get rid of disincentives To earning more!
