Understanding the Immigration Salary List (ISL) for UK Job Offers and Take-Home Pay

What is the Immigration Salary List (ISL)?

The immigration salary list (ISL) is a Home Office publication that sets reduced minimum salary thresholds for certain skilled worker visa applications. It replaces the earlier 'shortage occupation list' and is designed to attract talent to roles where the UK has a demonstrated labour shortage. If your job is on the ISL, you may qualify for a visa with a salary as low as £30,960 per year (2025/26 rate; check current figures on GOV.UK), compared to the general skilled worker threshold of £38,700. The ISL is reviewed regularly, and occupations can be added or removed.

How the ISL Affects Job Offers

When negotiating or comparing job offers, knowing whether the role is on the ISL can be a significant factor. Employers sponsoring a visa must pay at least the ISL rate (if applicable) or the 'going rate' for the occupation, whichever is higher. The going rate is typically based on ONS ASHE data for the specific occupation code. For example, a nurse might have an ISL rate of £30,960, but the going rate could be higher. Always confirm the exact salary requirement with your employer or a qualified immigration adviser.

For UK employees and job seekers, the ISL also influences the wider labour market. Roles on the list often face recruitment difficulties, which can give you leverage in salary negotiations. However, the ISL does not directly affect your tax or take-home pay – that depends on your gross salary, tax code, and deductions.

Comparing Gross Salary and Take-Home Pay

Once you have a gross salary figure, you need to understand what reaches your bank account. For 2026/27, the key deductions are:

• Income Tax: 0% on the first £12,570 (Personal Allowance), 20% on income from £12,571 to £50,270, 40% on £50,271 to £125,140, and 45% above £125,140 (HMRC rates).
• National Insurance: 8% on earnings between £12,570 and £50,270, then 2% above that (employee Class 1).
• Pension contributions: If you contribute via salary sacrifice, these come off before tax and NI, reducing your taxable income.
• Student loan repayments: Plan 1, 2, 4, or 5 deduct 9% above respective thresholds; Postgraduate Loan deducts 6% above £21,000.

For example, a gross salary of £38,700 (the general skilled worker threshold) with standard 1257L code, no pension, no student loan, gives take-home pay of about £30,000 per year – roughly £2,500 per month. If the same role is on the ISL at £30,960, take-home pay drops to around £25,500 per year. Use our take-home calculator to run your own figures.

Using the Take-Home Calculator

Our take-home calculator lets you input your gross salary, tax region (England/Wales/NI or Scotland), pension contributions, and student loan plan to see your net pay. This is essential when comparing job offers, especially if one offer is on the ISL and another is not. Remember that the calculator provides estimates; your actual payslip may differ due to tax code adjustments, benefits in kind, or bonus payments.

Scottish Taxpayers

If you work in Scotland, Income Tax bands are different: starter rate 19%, basic rate 20%, intermediate rate 21%, higher rate 42%, top rate 48% (2026/27). National Insurance and student loans remain the same UK-wide. A Scottish taxpayer on £38,700 would take home slightly less than someone in England – about £29,700 per year. Always select the correct region in the calculator.

Final Thoughts

The immigration salary list (ISL) is a useful tool for both employers and job seekers in the UK labour market. While it does not directly change your tax or NI, it can influence the salary you are offered. Always verify the latest ISL rates on GOV.UK and use our resources to understand your take-home pay.
