A recent Telegraph article (10 January 2026) paints a stark picture of Britain's tax system, profiling couples earning £100,000+ who feel financially squeezed despite high salaries. The piece highlights "cliff-edge" tax traps around the £100,000 threshold, skyrocketing childcare costs, and rising mortgage repayments, leading some to delay or forgo having children. While the personal stories are compelling, a deeper look at real incomes adjusted for inflation, historical tax band changes, and broader cost-of-living pressures reveals a more nuanced reality: these disincentives are real, but they affect a relatively privileged group amid widespread fiscal drag impacting millions lower down the income ladder.
The Article's Core Claims
The Telegraph focuses on families like Matthew and Nicole Griffiths, with combined incomes exceeding £200,000 (including side income), who faced £40,000 annual childcare bills for two children and mortgage hikes in 2022. Key points include:
- A 62% effective marginal tax rate between £100,000 and £125,140 due to the tapering of the personal allowance.
- Loss of child benefits (clawed back from £60,000, fully withdrawn at £80,000) and certain childcare supports.
- Childcare costs cited at £19,000 per child annually without full subsidies.
- Institute for Fiscal Studies (IFS) analysis suggesting no net financial gain until earnings exceed £144,500.
The article argues these factors punish productivity and make family life unaffordable for "wealthy" parents in the top 4% of earners.
Historical Tax Bands and Fiscal Drag
The £100,000 personal allowance taper was introduced in 2010 by George Osborne to phase out the allowance for high earners (£1 reduction for every £2 over £100,000, zero at £125,140). At the time, £100,000 put someone in the top 1-2% of earners; today, it's closer to the top 5-6%.
More broadly, income tax thresholds have been frozen since 2021 (personal allowance at £12,570, higher-rate threshold effectively at £50,270). This freeze, extended in recent budgets, creates "fiscal drag": as nominal wages rise, more income is taxed at higher rates without explicit tax increases.
The Office for Budget Responsibility (OBR) and IFS estimate this will pull millions into higher or additional-rate tax bands, raising billions for the Treasury. By 2029-30, the proportion paying 40%+ rates could rise significantly from pre-freeze levels.
The High-Income Child Benefit Charge (HICBC), introduced in 2013 at £50,000-£60,000, was raised to £60,000-£80,000 in 2024, easing the cliff edge somewhat. Yet the £100,000 taper remains unadjusted, amplifying its bite over time.
Real Incomes: Adjusting for Inflation
Nominal £100,000 sounds substantial, but inflation erodes purchasing power. Cumulative CPI inflation from 2010 to late 2025 is around 50-60% (with peaks above 10% in 2022). Today's £100,000 is equivalent to roughly £60,000-£65,000 in 2010 money.
UK real wage growth has been dismal: average real earnings are still below 2008 levels in many analyses, with stagnation through the 2010s and falls during high-inflation years. Recent nominal growth (4-5% in 2025) has outpaced inflation (around 3%), offering modest real gains, but this follows years of losses.
For £100k+ earners, real take-home pay feels squeezed not just by taxes but because thresholds haven't risen with prices or wages.
Cost of Living Pressures
Childcare is undeniably expensive, but national averages are lower than the article's £19,000-£40,000 figures (likely reflecting London/Southeast rates or pre-subsidy costs). In 2025, full-time nursery for under-2s averages £239 weekly in England (~£12,400 annually), down due to expanded free hours (15-30 hours for working parents from 9 months).
Mortgage rates spiked in 2022, pushing repayments up (as in the article), but many have since refinanced or seen rates ease slightly.
Broader costs: energy, food, housing hit everyone post 2022 inflation surge, but high earners have more buffer than median households (£35,000-£40,000 average).
A Fair Assessment
The Telegraph rightly spotlights perverse incentives: 62% marginal rates discourage extra work or promotions, and benefit withdrawals create "traps." Strategies like pension contributions (as the Griffiths advise) mitigate this, but not everyone can access them.
However, context matters. These families are in the income elite—HMRC data shows the top 1% pay 27% of income tax. Progressive taxation funds public services, and fiscal drag from freezes affects lower earners more proportionally (pushing teachers, nurses into 40% tax).
The system needs reform indexing thresholds to inflation, smoothing tapers, or rethinking child support universality but portraying £100k+ households as "broke" risks overlooking the struggles of average families facing similar drags on stagnant real incomes.
Britain's tax and cost-of-living squeeze is real, but it's a spectrum. High earners face unique cliffs yet remain far better positioned than most. Policy should address disincentives without dismantling progressivity.
