UK Youth Mobility Scheme deep dive for Australians

The UK Youth Mobility Scheme (Tier 5) is the longest WHV available to Australians at three years, and the most expensive to set up. This page covers what tax you will actually pay, how to time the NI number application, the jobs that hire YMS holders, and the mistakes that wreck the budget of most arrivals.

This is general information only, not migration, financial or tax advice. Check the live source pages before relying on the figures here.

UK income-tax bands (2025-26 tax year, England and Wales)

The UK tax year runs from 6 April to 5 April. Scotland sets its own rates; the figures below apply to England, Wales and Northern Ireland, where most YMS holders work.

YMS holders are UK tax residents from day one and get the full personal allowance. The allowance tapers away once you earn over GBP 100,000 (lose GBP 1 of allowance for every GBP 2 of income), which rarely affects WHV jobs.

National Insurance contributions (Class 1, employees)

NI is the UK's social-insurance tax. It funds the NHS and the state pension. Class 1 NI runs on top of income tax.

A YMS holder earning GBP 30,000 a year pays about GBP 1,394 in NI, on top of GBP 3,486 in income tax. Take-home is roughly GBP 25,120 (2026-27 rates, England).

National minimum and living wage

The National Living Wage for workers aged 21 and over is GBP 12.71 an hour from 1 April 2026. Lower rates apply to younger workers. Pay above the minimum depends on the employer and the job.

NI number application timeline

You cannot start the NI number application from Australia. The process needs you to be in the UK.

1. Week 1 in the UK: Apply online at gov.uk apply for an NI number. You will need your YMS BRP (biometric residence permit), an active UK address, and a phone number.
2. Week 2 to 4: HMRC may ask you to attend an in-person identity interview at a Jobcentre Plus. Bring your passport, BRP, and proof of address (tenancy contract or council letter).
3. Week 4 to 8: NI number letter arrives by post.
4. The day it arrives: Give the number to your employer immediately. Ask them to change your tax code from emergency code 0T or BR to the correct code (usually 1257L for the standard personal allowance).

While you wait, you can legally work. Your employer must use emergency code 0T or BR until you provide the number. This taxes you at 20 per cent or higher with no personal allowance, so you over-pay. Once HMRC has your number and a full tax-year history, they refund the overpayment automatically through PAYE or after you file a P85.

Common mistakes YMS holders make

1. Renting in Zone 1 or 2 on a hospitality wage. Central London rents are high compared with most hospitality wages. Many YMS holders share houses further out and budget for transport.
2. Skipping council tax registration. If you rent solo or as the lead tenant, you owe council tax. Full-time students get a 100 per cent exemption; YMS holders working full time do not. Failing to register triggers a backdated bill.
3. Using an Australian credit card for everything. International transaction fees add up over a year. Open a Monzo, Starling or Revolut account in your first week using your eVisa share code and a UK address (a hostel letter works for some banks).
4. Assuming you can travel to the EU freely. Brexit ended free movement. As an Australian YMS holder, you get the standard 90-days-in-180 Schengen tourist visa across the EU, the same as any other Australian passport-holder. You cannot legally work in any EU country on a UK YMS.
5. Working cash-in-hand for months and not declaring it. Cash-in-hand work is common in London hospitality and construction. HMRC matches PAYE records against bank deposits; large unexplained deposits can trigger a tax-evasion investigation that affects future UK visa applications, including a Skilled Worker or partner-visa route.
6. Forgetting to file P85 when leaving. The P85 is the form that triggers your end-of-employment tax refund. Without it, HMRC will not chase you; the money stays with them. File P85 the week you leave, even if you plan to return.
7. Booking a return flight that prevents the full three-year stay. The YMS visa is valid for 24 months as standard, extendable to 36 months once inside the UK by applying before the first 24 months expire. Many YMS holders book a return flight at the 22-month mark and miss the extension window.
8. Not paying private travel insurance for dental, repatriation and trip cancellation. The IHS gives you access to NHS care on the same terms as UK residents (including the usual NHS charges, such as for dentistry and prescriptions in England), but it does not cover repatriation to Australia in a medical emergency or a flight home if a family member becomes ill. Travel insurance covers those.

Settling your tax when you leave

The tax year ends 5 April. If you leave the UK mid-year:

• File form P85 with HMRC online. Attach your final P45 and any P60s.
• Provide a UK or Australian bank account for the refund.
• HMRC processes most P85 refunds in 8 to 12 weeks.
• If you have not received a final payslip with a P45, ask the employer to issue one before your last day.

If you were self-employed (Uber, Deliveroo, freelance work), you file Self Assessment by 31 January after the tax year, not P85. You can do this from Australia using your Government Gateway login.

What this means for your Australian tax

If you remain an Australian tax resident (the common case for short YMS stays), declare your UK earnings on your Australian return. Claim a foreign income tax offset for the UK tax paid. The Australia-UK double-tax treaty prevents you from being taxed twice on the same income.

If you became a non-resident for Australian tax purposes (broadly, you set up your "permanent place of abode" in the UK and intend to stay long-term), Australia stops taxing your UK income, but HECS-HELP repayment is still required if your worldwide income exceeds the threshold. See the working holiday visa tax basics page for the cross-border rules.
