Student loan repayments are collected automatically through PAYE — they apply whether you are on a permanent contract, internship, or placement. If your internship is shorter than a full year, your actual repayment will be proportionally lower.

What does a £42,000 internship salary mean in practice?

On a £42,000 internship salary, you take home £33,760/year (£2,813/month, £649/week, £130/day). Your net hourly rate — based on a standard 37.5-hour week — is approximately £17.31. Your earnings are 20% above the UK median salary of £35,000 and sit above the annualised National Living Wage (£12.21/hr × 35hrs = ~£22,369/year).

Because your salary exceeds the Plan 2 repayment threshold of £27,295, student loan repayments of £110/month (£1,323/year) are automatically deducted through PAYE. This brings your take-home down to £32,437/year. Your earnings fall in the Basic Rate (20%) band — for every £1 you earn you keep roughly 80.38p after tax and NI (before student loan).

Interns on a PAYE contract have the same tax treatment as permanent employees — Income Tax, National Insurance, and student loan repayments all apply at the same rates. If your internship is shorter than 12 months, HMRC may have over-collected tax due to the standard weekly/monthly PAYE spreading; you can claim a refund at the end of the tax year using a P800 or self-assessment.

On £42,000 you keep 80p of every £1 before student loan and 77p once Plan 2 deductions kick in (9% on the excess above £27,295). That works out at £32 of IT+NI every working day; your gross sits 1.76× the annualised National Living Wage (£23,810). Benchmarked against the typical UK graduate starting salary of £30,000 (net ~£25,120), you are £12,000 above that baseline. A London-weighted internship at ~15% uplift (£48,300 gross) would add £4,536/year to your net — before factoring in London rent typically £400-£600/month higher than regional cities. A £5,000 permanent raise post-internship would add £3,600 net (marginal rate 28%). You are using 100% of your £12,570 Personal Allowance, and saving 20% of take-home (£563/month) fills a full £20,000 ISA in 36 months.
