How might a £1 pay rise find yourself costing you almost £50,000? The reply is the childcare cliff edge within the UK tax system, which is able to get significantly steeper for higher-earning households from September.
The federal government’s enlargement of free childcare provision in England this autumn signifies that working households with kids aged below three will be capable to declare 30 hours of government-funded childcare every week on high of the tax-free childcare scheme. Priceless advantages, however the bulk of this entitlement is misplaced if one mother or father’s adjusted web revenue is greater than £100,000 per 12 months.
This threshold, launched in 2017 when the rollout of free childcare first started, has by no means been elevated. As “fiscal drag” takes extra taxpayers over the £100,000 cliff edge, mother and father are discovering {that a} small pay rise can depart them considerably worse off.
From September, a mother or father in London with two kids at nursery who handed this level would wish to earn greater than £149,000 to compensate for the lack of childcare assist from the state, in line with new calculations by the Institute for Fiscal Research — a pay rise of just about 50 per cent.
The yawning gulf means high-earning mother and father are opting to restrict their earnings by lowering their working hours or making outsized pension contributions to hold on to their childcare advantages.
With lots of of hundreds extra taxpayers forecast to cross the £100,000 threshold by 2028, specialists warn the “behavioural response” from increased earners might have penalties for office productiveness and financial progress — to not point out the rising complexity for households managing their funds.
Though increased earners can use varied strategies to remain on the best aspect of the cliff edge, new mother and father concurrently navigating the tax and childcare techniques face a steep studying curve. Many FT readers of their 30s and 40s who responded to our current name out mentioned they had been completely unaware of the complexity awaiting them. Figuring out how finest to handle this varies vastly between households.
FT reader Davina* works in finance, and has two kids below the age of three in nursery. Though she earns a six-figure wage, it’s not excessive sufficient to compensate for the worth of the childcare advantages she would lose. She has stayed below the £100,000 threshold by dropping all the way down to a four-day week and paying her bonus into her pension.
“This year, we are £250 per month better off as a result, although I know that going part-time has affected my promotion prospects,” she says. “I feel bad for complaining, as we aren’t poor, but we’re still spending £2,750 per month on childcare even after the government help, and the reduction in my take home pay means we can’t afford holidays or a car.”
Money circulation pressures and rising mortgage charges imply some can not afford to make outsized pension contributions to stay below the edge.
Rob works in tech. Since his daughter was born 5 years in the past, he has turned down two promotions that will have taken his pay over £100,000 as he couldn’t negotiate a excessive sufficient pay rise to compensate for the lack of childcare hours. Finally, he give up his job and have become a contractor. “This is riskier, but my earnings have jumped to the point where it is worth it,” he says. “My wife and I have decided to have no more children to maintain the quality of life we have with the one.”
From September, the enlargement of free childcare in England is about to shift the monetary equation once more. The IFS calculates {that a} mother or father in London with two kids aged below 3 at nursery would wish to earn over £149,000 for his or her disposable revenue after childcare prices to be as excessive as one incomes £99,999 (this assumes 50 hours of childcare per week at London’s median hourly price, funded from their web pay).
Exterior of the capital, the place the price of childcare is barely decrease, the IFS says the break-even level can be round £137,000 for 2 kids receiving 40 hours of assist at England’s median hourly price.
Freezing tax thresholds has proved a strong approach for successive chancellors to extend the tax take with out altering headline tax charges. Had the childcare cliff edge risen in keeping with inflation since 2017, it might now be over £130,000. Nonetheless, high-earning mother and father face a second situation, as hitting a six-figure wage can also be the purpose within the tax system the place the £12,570 tax-free private allowance begins to be eliminated.
People should pay a marginal price of 60 per cent on the slice of revenue between £100,000 and £125,140, and 45 per cent above this degree (word tax charges are increased in Scotland). This has turn into often known as the six-figure wage entice as all too usually, receiving an surprising tax invoice is how staff discover out about its existence. Staff sometimes have to finish a tax return to pay what they owe, as it’s too complicated for the PAYE system to calculate and acquire.
Launched in 2010, had the £100,000 threshold elevated in keeping with inflation it might now kick in above £150,000. Presently, 1.8mn UK taxpayers earn sufficient to be impacted, however as thresholds stay frozen, the IFS estimates this might enhance by 20 per cent to 2.2mn within the subsequent three years, primarily based on its evaluation of OBR forecasts.
As extra taxpayers are dragged into these increased charges, the “distorting” results of extra staff making an attempt to keep away from steep cliff edges within the system will probably be amplified.

Frequent behavioural responses of working much less or limiting taxable pay stand to have a higher financial affect as extra taxpayers hit these limits. In addition to working counter to the federal government’s progress agenda, this additionally raises the query of how a lot additional tax will truly be raised.
“If people are turning away work, that’s in principle resulting in lower productivity and growth,” warns Dan Neidle, founding father of the Tax Coverage Associates think-tank.
“There shouldn’t be hard thresholds that radically change people’s behaviour,” he says. “The best research suggests the revenue maximising tax rate is 55 per cent. That’s very close to the current top rates of income tax plus national insurance. But the abnormally high marginal rates at £60,000 [where child benefit starts to be tapered away] and £100,000 are much higher than this.”
Rising pension contributions is among the best methods of lowering your adjusted web revenue (your whole taxable revenue minus sure tax reliefs) below the £100,000 threshold. That is definitely tax environment friendly, however locking cash up inside a pension till the age of 57 limits discretionary spending at a time when mother and father face a number of monetary pressures.
Sean* paid £55,000 into his pension final 12 months to remain below the edge, leaving his household on a really tight funds. His youngster’s nursery has simply introduced it can enhance charges by £1,600 a 12 months from April, citing the affect of upper employer nationwide insurance coverage contributions. “It just all seems so regressive as a policy,” he says.
“At the moment, we have nothing left over at the end of the month,” says Verity*, a excessive earner with two kids who has been making massive pension contributions to remain below the edge. “It’s like not having had a pay rise for six years when everything around you has increased; mortgage interest and monthly bills being the massive ones. On the flip side, my pension is looking pretty healthy, so I guess I’ll reap the rewards in 30 years.”

The complexity of the monetary calculations concerned might but increase one space of the UK’s providers economic system — extra mother and father are in search of tax recommendation.
“People typically want to know if there’s a magic number where it becomes worthwhile ‘pensioning down’ to reduce taxable pay,” says Philly Ponniah, a licensed monetary coach in London who affords group workshops and one-to-one classes to assist mother and father navigate the system.
The reply will rely on “a huge number of variables” together with exactly how nursery charges are calculated — a darkish artwork in itself — if pupil mortgage repayments are nonetheless being made, and whether or not mother and father can afford to pay their lease or mortgage in the event that they enhance their pension contributions.
If employers provide pension preparations utilizing Wage Sacrifice, it’s comparatively simple for staff to regulate their contributions. Nonetheless, many corporations solely have a brief “window” of some weeks per 12 months when modifications could be made (in Ponniah’s expertise, many HR departments will enable modifications if workers ask properly, however don’t wish to promote this).
Utilizing office wage sacrifice schemes to purchase electrical autos, electrical bikes or further annual depart entitlement to take salaries below the edge are all generally used.
The state of affairs is extra complicated for staff in outlined profit pension schemes. FT Money has spoken to oldsters working as NHS medical doctors who say they’re turning down additional shifts to stay under the childcare threshold (see field).
Different high-earning mother and father within the non-public sector mentioned that they had turn into self-employed, utilizing a restricted firm construction to maintain wage and dividend funds below the edge, with a view to growing these when their youngster began faculty.

Single mother and father are caught between a rock and a tough place. “You can have two people earning £60,000 a year who get everything, including full child benefit, versus one person earning £120,000 who loses their funded hours, child benefit and tax-free childcare,” Ponniah says.
Inside {couples}, she notices that “an awful lot of people, women mostly” are squaring the circle by going part-time, and even giving up work fully. “I see a lot of female higher earners go down to four days a week, yet in many cases they still end up doing five days work,” she says.
For {couples} the place a higher-earning associate has gone by way of the edge, the scale of pay rise wanted to fund the extra childcare prices usually exceeds the decrease earner’s wage: “I encourage couples to think about childcare as a household expense, but women often feel if their salary won’t cover the childcare costs, there is no point.”
Monetary planning even extends to household planning. Ponniah has observed extra skilled {couples} are delaying attempting for a second child till their first youngster begins major faculty. “Either they manage the childcare costs by having a bigger gap, or by just having one child. Tragically, some couples realise they’ve left it too late.”

Forward of a difficult Spring Assertion subsequent week, tax reforms that will profit increased earners are politically unattainable for the chancellor to contemplate.
“The overwhelming majority of parents earn less than £100,000, and too often it’s the most disadvantaged families who miss out on the support they need,” a authorities spokesperson mentioned.
“Giving every child the best start in life is central to our mission to break the unfair link between background and success — this starts with increasing access to quality early education.”
But the most important downside for a lot of excessive incomes mother and father is ignorance — they merely don’t know in regards to the tax penalties of incomes a six-figure wage, so they can’t plan for it. Maybe understandably, official authorities net pages don’t illustrate the issues and options in a approach that will assist increased earners navigate the tax system to their benefit. However the rising affect within the office signifies that extra employers are taking pre-emptive steps to coach their workers.
“Employers are definitely starting to understand what a big problem this is, especially as more younger employees enter the six-figure earnings bracket,” says Caroline Harwood, associate and nationwide head of employment tax at BDO. She is noticing extra employers proactively serving to workers to handle the monetary fallout, from working tax workshops to elevating consciousness of wage sacrifice schemes.
One senior HR chief mentioned it might be simple for corporations to crunch their payroll information and situation written alerts to workers when their earnings go a sure level, say £90,000. She added that many corporations have already got comparable “trigger warnings” in place for employees incomes near £200,000 who danger hitting the annual allowance taper on their pension contributions.
Nonetheless, corporations are extraordinarily cautious of being seen to provide workers tax recommendation. Harwood says some are making monetary recommendation from third-party corporations out there as a workers profit. BDO has additionally acquired a file variety of inquiries this 12 months from employers who wish to discover offering a office nursery.
Staff shifting jobs are higher in a position to argue for a pay rise. London-based lawyer Tom* has two younger kids, and was provided a brand new function on a wage of £110,000. He efficiently negotiated this as much as £130,000 after displaying his new employer how it might affect his household financially.

He was not the one FT reader to succeed with such a tactic, nonetheless, this can solely work in a restricted variety of professions. Far higher numbers of readers reported being hit with massive tax payments after unwittingly getting into the ‘trap’ or getting their calculations flawed. Teresa, an FT reader, has needed to pause her fertility therapy after a promotion at work final 12 months took her over the £100,000 threshold: “I had no idea that my new salary was going to result in such a huge tax bill. This has had a hugely negative impact on our ability to start our family.”
The timing of bonuses, that are sometimes paid on the finish of the tax 12 months, makes it tougher to navigate the edge. Extra corporations are providing workers the choice to “pension their bonus” upfront, however mixed pension contributions from workers and employers can not exceed the annual allowance of £60,000 with out triggering a tax cost.
The price of scrapping the £100,000 cliff edge and making childcare assist common would seemingly price within the low lots of of thousands and thousands, the IFS estimates.
As for the tapering away of the private allowance, even when there was political want to simplify the system for increased earners, this have to be weighed in opposition to the large quantity of tax income being raised.
The IFS estimates that abolishing the 60 per cent price would price about £7bn in misplaced tax revenues per 12 months, rising over time as the consequences of ‘fiscal drag’ enhance. Nonetheless, the true price can be decrease if extra increased earners responded by growing their taxable revenue — by way of working extra hours, or saving much less into pensions.

A future chancellor might fund eliminating the taper by adjusting increased price tax thresholds to compensate. Nonetheless, for this to be income impartial, the IFS estimates the 45 per cent tax threshold would must be lowered from £125,140 to someplace between £60,000 and £70,000. “The government might conclude that’s not a vote winner, and they’re better off complicating the financial lives of a smaller number of very high earners,” says Stuart Adam, senior economist on the IFS.
Neidle believes a extra believable answer can be growing the highest price of revenue tax above 45 per cent, although increased earners would complain bitterly about it.
“The political cowardice of successive governments got us into this mess, with ‘tricks’ to hide the true rate of tax,” he provides. “What was initially a small anomaly has been magnified by fiscal creep into a serious problem.
Political bravery is required to tackle it. It remains to be seen if the current government are brave enough.”

The tax entice and the NHS
The £100,000 childcare cliff edge is a selected downside for medical doctors given the unsociable, lengthy working hours they steadily undertake and the complexity of the NHS outlined profit pension scheme.
FT Money has been contacted by NHS workers who say they really feel the one fail-safe approach of retaining their childcare advantages and maintaining their pay under the £100,000 threshold is by turning down shifts, because of the problem of calculating their annual pensions allowance.
“I am a hospital consultant, and feel trapped by this,” says Martha*. “I have tried to put as much as possible into my NHS pension, but I am really worried about what my tax bill is going to be next year. I can’t take on any extra work for the NHS because it would penalise me too much.”
Nikita and her husband each work for the NHS and have one youngster. As he earned over £100,000, he arrange a self-invested private pension (Sipp) believing he had scope to make further pension contributions to take him under the edge. Nonetheless, he acquired a tax invoice in January for over £8,000.
NHS workers reducing their hours at a time when the federal government is urgently attempting to cut back ready lists is a strong political argument for tax reform. Tax specialists word Labour’s U-turn final summer time on reinstating the pensions lifetime allowance (LTA), which was pushed by the affect of medical doctors saying they might be compelled to take early retirement.
In a current British Medical Affiliation survey, a number of medical doctors mentioned that they had lowered their hours to remain under the childcare eligibility threshold and make sure that they weren’t worse off, together with these working in most cancers care and psychiatry that are key areas of focus for the federal government.
The BMA is looking for the £100,000 childcare threshold to be eliminated, arguing in its February spending assessment submission: “Fixing this is an increasing necessity therefore, in the context of increasing staff shortages, and an increasingly female workforce.”
