UK Tax and National Insurance for Skilled Workers is a subject that touches every professional making the UK their new home. Beyond visas, job offers, and relocation plans, there’s the day-to-day reality of understanding how your earnings are handled once you start working. For many, it can feel like stepping into an unfamiliar system with its own rules, codes, and processes. This article takes you through that journey with clarity — unpacking how your pay is managed through PAYE, what those mysterious tax codes and NI categories really mean, and when you may need to take action with a Self-Assessment. We’ll also highlight the tools that help you see your real take-home pay and explore the recent changes that matter most to newcomers. By the end, you’ll have a clearer picture of how everything fits together, leaving you more confident in both your finances and your future in the UK.
What’s New for Skilled Workers in 2025?
Before diving into taxation, it’s useful to touch briefly on the Skilled Worker visa landscape in 2025. As of 2025, significant reforms raised the general salary threshold to £41,700 per year, or the “going rate” for the specific occupation—whichever is higher.
Further, most eligible roles must now meet RQF Level 6 (degree-level) criteria. Exceptions exist via the Immigration Salary List (ISL) or Temporary Shortage List (TSOL), but these come with stricter conditions—such as exclusion from bringing dependants or progressing to settlement.
These reforms underscore that the UK is steering its immigration framework toward highly skilled, higher-paid roles. As a visa holder, your tax and NI matters operate within this revised framework, but fortunately, the taxation system itself remains consistent for everyone.
PAYE System: How Your Tax and NI Are Collected?
PAYE (Pay as You Earn)
If you’re employed under your Skilled Worker visa, your income tax and NI are typically collected via the PAYE system:
- Income Tax is deducted according to your tax code and the current rates.
- National Insurance contributions are applied through Class 1 (for employees) at standard rates.
Tax Codes
Your employer uses your tax code to calculate your tax-free allowance and deductions. Keep an eye on your payslips to ensure your tax code is correct, especially when you start your job, change roles, or have additional income.
National Insurance Contributions Explained
NI Categories
Most Skilled Worker visa holders fall under Class 1 NI:
- Employees contribute Class 1, taken directly through payroll.
- You’re eligible to apply for a National Insurance number once in the UK to begin these contributions.
Temporary Exemptions:
If you’re seconded to the UK by your home-country employer and can provide appropriate social security documentation (e.g., A1 or equivalent forms), you may be exempt from UK NI for up to 52 weeks. This provision allows you to avoid double contributions during short-term assignments.
UK Income Tax Rates and Bands
If you’re working in the UK under a Skilled Worker visa, your earnings will be taxed according to set income bands. Most people have a standard Personal Allowance of £12,570, which means you don’t pay any tax on that portion of your income. Everything above this is taxed in stages, depending on how much you earn.
Do note: if you’re based in Scotland, the tax bands and rates differ slightly, as Scotland sets its own system.
Here’s how it works for the rest of the UK:
- Personal Allowance – Up to £12,570 → 0% tax
- Basic Rate – From £12,571 to £50,270 → 20% tax
- Higher Rate – From £50,271 to £125,140 → 40% tax
- Additional Rate – Over £125,140 → 45% tax
When Self-Assessment Is Required?
You’re typically on PAYE, so you may not need to file a Self-Assessment tax return—unless you:
- Are self-employed in the UK
- Have additional UK income (e.g., rental, savings, foreign income, pensions)
- Completed disposals (e.g., selling property or investments).
If any of these apply, registering for Self-Assessment becomes essential to declare your income manually.
HMRC Tools for Estimating Take-Home Pay
To plan your finances, HMRC offers useful tools:
- PAYE tax calculators that estimate net pay after tax and NI.
- “Check if you need to send a tax return” tools to confirm if Self-Assessment applies.
These resources help you understand your take-home earnings and tax obligations before payday.
Bringing It All Together
Let’s walk through a typical scenario for a Skilled Worker visa holder in 2025:
- You begin a job with a sponsor; your CoS meets the new salary threshold (>£41,700) and you likely hold a degree-level role.
- You receive a tax code and begin earning.
- Your employer deducts:
- Income Tax via PAYE
- Class 1 NI contributions
- You monitor payslips to ensure deductions align with current thresholds.
- You use HMRC’s tax calculator to evaluate your net pay.
- If you have additional income (e.g., rental income or foreign interest), you file Self-Assessment.
- Optionally, if your posting is temporary and you have valid social security documentation, you may be exempt from NI for up to 52 weeks.
