100k tax trap is lame

It's totally illogical. Even ignoring the childcare bit, the total tax % is higher for someone earning say £100k than someone earning £150k. That goes against progressive taxation. But at least earning more means taking home more. Once you add in the childcare cliff you can actually take home less for earning more. It's totally illogical and it's irrelevant that it's hitting people who are well off. I don't earn £10k but I can still see it doesn't make sense.

Ah so we’ve moved from changing careers to temporary breaks from work or cutting hours now. The mental gymnastics are giving me whiplash.

There are no ‘mental gymnastics’ - these are the decisions people make, when the cost of childcare is so high.

Why are you so averse to the idea people might change how they work, when they work, if they work, how they pay themselves etc due to the high cost of childcare?

Two in nursery could cost you £50k a year - it’s not too difficult to imagine someone might opt to take a ‘career break’ if they aren’t clearing their nursery bill in net income - given they would otherwise be paying to go to work.

Basic rate taxpayer here without a hope in hell of ever being trapped at £100k but I think it’s grossly unfair and wrong.

I believe everyone should have a personal allowance no matter what. I strongly want the tax system generally to be more equal - make all forms of income taxable as tax from work should not be higher than passive income or from gains (including those benefits that are currently tax free). Absolutely get rid of cliff edges, they will always lead to avoidance. Just think also of the lost tax revenue of all those who go part time to avoid the 100k thing! We all lose because of this,

A fairer system should also reduce people legally reducing or avoiding tax through things like pension contributions or salary sacrifice schemes. On a separate note I would review these schemes and many other tax exempt or similar schemes as lost potential revenue is also a cost, and is a political choice.

But salary sacrifice doesn’t avoid tax - the tax just becomes payable later, when the person retires and receives their pension. Someone sacrificing heavily into their pension may well be in a position to retire earlier and so end up paying tax on their pension income for longer because they took it earlier too.

No it's not unfair. These moany threads get started approximately once a week and it's not a good look. It's like people sitting snug on a boat insisting they have a right to keep their life jacket on because it makes them more comfortable when there are people in the water who have no boat and no jacket.

The "trap" you are referring to is simply the action of help being withdrawn that you simply don't need and only think you need because you think you are entitled to a more comfortable lifestyle than you can quite reach.

Yes there is a bit of a plateau in the rate at which your lifestyle comforts can increase when you are at that level. That is ok because you are at a level far above the level at which people are struggling. Metaphorically, it's like a platform that is located above the danger zone and all the help and rescue efforts are about helping people to reach that platform or get closer to it, and there's minimal help available for climbing up further. You are only struggling if you have managed your resources badly and taken on financial commitments that are too much for your income.

If your income is just above the "trap" level you can make extra pension contributions to keep below the trigger points.

If the amount by which your income exceeds the trigger points by too much for that to be viable then you are a wealthy person on every objective measure and are merely suffering from a mismatch between the even higher level of wealth you think you shoukd be entitled to vs actual reality.

Is it not also a question though of whether you’d welcome more tax being paid into the economy? If all these money is going into pensions, it’s not going to tax is it. If the threshold was increased, it would mean these high earners that people are so bitter about would be paying more into the economy rather than their pensions.

Then you play the long game - 5 years of childcare - after those 5 years when the cost reduces you’re able to take home more.

There is still limited incentive to only keep 38p in the pound of my salary, it makes more sense to keep under the threshold and retire early. I don't plan to stop the salary sacrifice unless the thresholds change.

What about the nurses and police who are stopping work because it’s unaffordable without childcare support, but their partner earns over the threshold?

There will be plenty of (mainly women) in teaching / nursing type roles whose households will be concluding it’s better to stop working or reduce hours because they can’t claim any childcare help.

Do we want that? As it’s happening.

Uniforms which have to be washed which was the subject under discussion. With the current shortage of nurses and police officers do we really want them pursuing other careers?

Redburnett · 17/09/2026 09:47

One of my DC works with high earners, many have children. Apparently many manage their working hours and therefore salaries to stay below 100k, to avoid the 'penalties'. It really does not make sense that they need to do this.

JustAnotherWhinger · 17/09/2026 09:46

Shatenoeuf · 17/09/2026 08:15

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.

I’ve said this about state nurseries ever since the introduction of tax credits caused nursery fees to boom.

So having children is a choice and shouldn’t attract tax relief on childcare as a result…. But nursing and police are what, some form of indentured servitude they can’t escape from? Other careers are available.

And I’m pretty sure both of these careers will be given uniforms by the employers…?

JustAnotherWhinger · 17/09/2026 09:43

I think there should be a taper or it should be based on household income.

We get no child benefit and no childcare hours, but BIL and SIL, who have the same household income as us, get both. That’s not a fair system.

But the only reason they’re doing this is because the tax system has been designed in such a way to exclude ~3% of parents from claiming childcare help.

5 years of wasted energy trying to stay under the cap, working part time, the government losing even more tax revenue due to large pension contributions they wouldn’t have otherwise made…

… what’s the benefit, for anyone?

There is so much talk about growth - and yet we are intensively incentivising our highest earners (who will be paying >50% of all tax) to… work less and avoid paying tax via pension contributions exclusively to allow them to claim childcare help.

Id love to see the numbers to justify it - I’ve seen FOI requests and the treasury don’t seem to have an answer.

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.

Financial independence is too important to most of us to throw it away because it negatively affects a minority for a limited period of their lives.

Childcare that is necessary to do your job should be tax deductable. Obviously. If you can claim back washing the uniform you need you should be able to claim back childcare.

Of course people can always earn less. But frankly the unfairness is the least problematic thing, it's entirely counterproductive. It should always be worth earning more.

It's mad, isn't it? People who are evading the law and fiddling their taxes are the ones who will be having to look over their shoulders all the time and looking for loopholes to find workarounds that aren't really 'in the spirit' of honesty; it shouldn't be something that ever has to remotely concern people who are legitimately earning well and openly and honestly making their fair tax contribution as a result, to have to 'fight back' against the government's grossly unfair rules.

Burntatbothends · 17/09/2026 09:07

It isn't if it effectively means your income is capped for many years and does not increase with inflation. Every year my spending power decreases. I would have to earn another £20k at least for it to be worth me taking the tax hit, that's not going to happen quickly.

Then you play the long game - 5 years of childcare - after those 5 years when the cost reduces you’re able to take home more.

Didimum · 17/09/2026 09:24

Regardless of any other reason (which are valid too), it’s ridiculously unreasonable that it has not moved with inflation for donkeys years. Fiscal drag at its finest, disincentivises people to work into opportunities and only incentivising high earners to salary sacrifice so they won’t be worse off, rather than to get the tax back into the economy.

Yes, I can't believe that this is up for debate - and I say that as a disabled person who is unable to work enough hours to even earn 5 figures.

If somebody earns over £100K, they're already paying a load more tax than somebody on £20K, so the basic system has worked well, without tugging at the roots to take even more from them as a non-progressive punishment for earning well. Why should they get the TFA? Why shouldn't they?

It's like with the winter fuel allowance, and you get people arguing that mega rich celebrities like Mick Jagger also qualified... so what? He earns an enormous amount of money - which means that he pays an enormous amount of tax, as he should. The more you earn, the less material any free allowance that means something significant to ordinary people actually is to you or to the country in terms of your overall contribution.

Seeking to take basic universal entitlements from people is a slippery slope. What would happen if we said that people earning over a certain amount would no longer be allowed to use the NHS, or to send their children to state schools, on the grounds that 'they earn enough not to need it'? Yes, mega rich people likely choose to go private for these instead; but they shouldn't have the entitlement forcibly removed from them... especially as they are amongst the net contributors paying the lion's share for them in the first place.

Cliff edges are so very obviously a poorly-thought-out, ineffectual, unfair policy that are designed to inhibit growth and to hurt the economy. It's the same with small businesses and VAT registration: even all the honest ones that don't massage their figures and ask for cash to avoid putting extra work through the books are thus strongly incentivised to turn away work and limit their turnover, and thus limit the amount of tax that they pay. Nobody in their right mind is going to want to suddenly have to charge 20% more for every job they do, only to not see a penny of it themselves and to have a lot of ongoing extra admin to do on behalf of the government.

Problem there though is:

  1. you have to cap your income at £100k. Thats a bit over £5k after tax with a student loan. A mortgage of £500k is around £3k a month. Having to cap your income for several years presents a real challenge in HCOL areas. And of course this threshold has been frozen for a decade already - and every year living costs increase.
  2. If you can put money in your pension, it just kicks the problem along to those earning above ~£150k - and then people still change their behaviour as a result, predominantly working part time. Or - their partners stop working instead, taking a person out of the workforce entirely.

I find it bizarre that leading a car is seen as something legitimate for government tax relief, but not childcare. I don’t need an expensive car, I go to work on the train - I do however need childcare to enable me to work!

It’s a backwards system and I think the government must have some kind of financial gain to propping the car industry up.

Completely agree , but the government has created a system where the lowest and highest earners are penalised the most by working more. Work extra hours and claiming UC you would only see around 30p in every pound after tax and deductions. high earners lose childcare, CB and pay extortionate tax. The whole thing needs a reform.
