Student Loans Add A Hidden 9% Tax To Graduate Pay

ended 22. July 2026

The debate about university costs usually stops at the size of the loan, but the number that really shapes a graduate's take-home pay is smaller and quieter: 9 per cent. Student loan repayments are collected like a tax, taken at 9 per cent of income above a set threshold, on top of Income Tax and National Insurance. For a graduate earning above that threshold, the effective deduction on the next pound earned is meaningfully higher than the headline tax rates suggest. Because the repayment thresholds have been held down rather than tracking earnings, more graduates cross them and repay for longer, so the loan behaves less like a debt you clear and more like an extra rate of tax you carry for much of your working life. That is what makes the apprenticeship route worth a second look: earning while training, with no tuition debt and no 9 per cent to follow. The people affected are school leavers weighing university against the alternatives, often without anyone setting the true lifetime cost side by side.

  1. Is describing the student loan as a hidden 9 per cent tax fair, or does it overstate the burden on graduates?
  2. Who loses most from frozen repayment thresholds, and does the graduate premium still stack up once this deduction is counted?
  3. What should a school leaver or parent weigh when comparing university with an apprenticeship, and do you advise clients or family on this? If so, please give as much colour and detail as possible.

Picture a school leaver weighing a degree against an apprenticeship. The figure that decides it is rarely named: 9 per cent. Above the threshold, that 9 per cent sits on top of income tax and National Insurance. For a basic-rate earner that is 20 plus 8 plus 9, so 37 per cent on the next pound, and a pay rise is worth 63p, not the 80p you would expect. Is it fair to call that a hidden tax? It is a loan, and anything left is usually written off. But it leaves your pay before you see it, so it behaves like one. A school leaver starting an English degree now is on Plan 5: 9 per cent above £25,000, cleared only after 40 years. The freeze in the news is a different plan, Plan 2 at £29,385, which holds more existing graduates in the 9 per cent for longer. For many degrees the premium still wins. For some, this is why it does not. An apprentice earns while training, with no tuition debt and no 9 per cent to follow. Weigh the pay a course leads to, not its sticker price.

Many people will never fully repay the balance before it’s written off but it can weigh on people throughout this time seeing the interest growing and repayments not even denting the principal. The real winners are those with very high earnings who clear the loan quickly. Middle earners often lose most because frozen thresholds pull more of their pay into repayments for longer. University can still deliver a strong financial return, but that depends entirely on the course, career and expected salary. I always encourage families to compare the lifetime cost, not just the tuition fees. An apprenticeship can mean earning from day one, avoiding student debt and building experience, while some professions still require a degree. The right choice is the one that delivers the best long term outcome.

It's the combination of the deductions and the psychological weight of the debt that means whether to go to university now is a much more serious decision than it used to be. It's become a really expensive route to 'find yourself' and getting the decision wrong could really limit your financial future. If the job you want to end up in has an apprenticeship route, it's well worth considering as the practical experience is what's going to compound your career progression.

Let's call it what it is. That student loan isn't really a loan. It's a 9% tax with a graduation gown on. Income Tax, then National Insurance, then another 9% on everything over the threshold. And because those thresholds have been frozen, more graduates pay it, for longer, often for most of their working life. You don't clear it, you carry it. Nobody sits a 17 year old down and shows them that number. They see the prospectus and the freshers photos. They don't see thirty years of a quieter payslip. Meanwhile the apprentice earns while they learn, walks out with no debt and no 9% shadow, and often lands in real work faster. And here's the bit from someone who hires people. I have never once cared where somebody went at eighteen. Only what they can do. University can still be brilliant. Just sell it honestly. A degree is one road, not the only one, and the smart money reads the small print before signing, not after.

Some university courses now look less like a ladder of opportunity and more like a very expensive treadmill. Calling student loan repayments a hidden 9 per cent tax is fair for many graduates, because that is exactly how it feels in the payslip: taken automatically, on top of Income Tax and National Insurance, long after the freshers’ week glow has worn off.

The disgrace is that too many young people are sold the dream without being shown the invoice. Frozen repayment thresholds mean more graduates are dragged into paying sooner and for longer, while some degrees simply do not deliver the earnings boost needed to justify the cost.

University can still be a brilliant investment, but it is not automatically the golden ticket. School leavers should compare the likely earnings, debt, repayment years and career route against apprenticeships, where they can earn, train and avoid starting adult life with a 9 per cent shadow tax.

Students have been sold a dream of university providing well-paying jobs, but only some degrees provide this. My children are currently weighing up their options, and I have told them we need to look at the return on investment of a degree. Courses like medicine and economics have huge lifetime earnings, but an arts degree is more likely to leave you with high debt, so look for ways that won’t hamper your future finances, like saving for a house.

The 9% repayment is just the tip of the iceberg for Plan 2 borrowers; interest on most plans is capped, but theirs increases if salary does. For someone who earns £66,000 with a university debt of £55,000, they will repay £3,295 every year, but only pay £9 off their loan as the interest amounts to £3,286. Middle earners are hit the hardest, as they are stuck paying what feels like a lifelong subscription, whereas higher earners will clear the debt before interest hits hard, and low earners pay little to nothing before the loan is written off.

Calling it a hidden 9% tax is slightly provocative, but it captures how the system feels in practice. Graduates only repay above the relevant threshold, so those who benefit least may repay little or nothing. But for a successful graduate, it’s an extra 9% on every pound above it - a basic rate earner can keep just 59p of the next pound, rather than 68p, potentially for 40 years.

University still delivers a substantial premium for many careers, but it shouldn’t be the automatic gold standard. A healthy economy needs skilled apprentices as much as graduates. Earning while learning, with no student debt and no 9% shadow, means pensions, savings and a house deposit can start compounding years earlier. The right question shouldn’t be simply “which university?” but which route offers the best return for the individual.
