NI number, PAYE tax and claiming refunds

1. 1

   Confirm you're eligible to work

   Check your Student visa conditions (usually up to 20 hours/week in term time, full-time in holidays) before applying for jobs.

2. 2

   Apply online at gov.uk

   You'll confirm your identity, often digitally via your eVisa/UKVI account rather than a face-to-face appointment, depending on current process — check gov.uk for the exact current route.

3. 3

   Start work while you wait

   You can legally start a job before your NI number arrives — tell your employer you've applied, and give them the number as soon as it's issued so it can be added to your payroll record.

Everyone gets a tax-free Personal Allowance each tax year (6 April to 5 April) — income up to that threshold is untaxed; income above it is taxed in bands. As a part-time student worker, your total annual earnings often sit below or only slightly above the Personal Allowance, meaning you may owe little or no income tax — but National Insurance is calculated per pay period, not annually, so it can still be deducted even in a low-earning month. Verify the current Personal Allowance and tax band thresholds on gov.uk, as they're set fresh each tax year.

If your employer doesn't yet have your P45 (from a previous UK job) or a completed starter checklist, HMRC has your correct tax code, you'll likely be placed on an emergency tax code, which can tax your first payslip more heavily than it should be — sometimes assuming you'll earn that same amount every month for the rest of the year. This is temporary and correctable.

1. 1

   Check your tax code is correct

   Use HMRC's online tax code checker or your Personal Tax Account (gov.uk) once your NI number is active.

2. 2

   Often it self-corrects

   Many overpayments are automatically refunded within a few payslips once your employer receives the correct tax code from HMRC.

3. 3

   Claim directly if it doesn't

   If you've left the job or the tax year has ended without a correction, apply for a refund directly through your Personal Tax Account on gov.uk, or by post using the relevant HMRC form.

Employees pay Class 1 National Insurance once their earnings in a pay period exceed a set threshold, at a percentage rate set each tax year. Both the threshold and the rate are set by HMRC annually and have changed in recent years — check the current figures on gov.uk before estimating your take-home pay.

A property occupied only by full-time students is entirely exempt from council tax. If you live with even one non-student, the household may get a discount rather than a full exemption — check your specific household composition. The exemption is not automatic: your university's student registry issues a council tax exemption certificate (usually downloadable from your student portal), which you send to your local council. Do this as soon as you have a fixed address, since councils can otherwise start billing you.

Most full-time international students are UK tax resident under the Statutory Residence Test once they've been here a certain amount of time in a tax year, which can in principle bring worldwide income into scope — but the UK-Bangladesh double taxation agreement and specific reliefs may reduce or eliminate double tax on any Bangladeshi-source income (e.g. rental income, family business income) you continue to receive. This is genuinely case-specific: if you have any ongoing income or assets in Bangladesh, get a proper assessment from your university's tax workshop or a qualified adviser rather than assuming either way.
