The foreign worker tax is a proposed levy on employers to make hiring migrant labour more expensive and reduce the employers’ National Insurance contributions for their own workers. It is not legal, but it is a campaign ambition — and it has been championed by the party Reform UK – and is already causing concern in certain industries such as care and agriculture, where a large proportion of the workforce comes from overseas. If introduced, it would sit on top of (not in place of) the current PAYE, National Insurance and Skilled Worker Visa sponsorship costs and increase the cost of employing workers from abroad.
Quick Facts: UK Foreign Worker Tax
What it means: It proposes to place a charge on employers who employ individuals from outside the UK, primarily for lower-paid jobs.
- Who is proposing it: Reform UK (in the context of a wider net migration policy platform).
- What it is: A policy pledge rather than existing legislation is in place.
- Current status: Employers’ National Insurance contribution for British employees will be reduced in line with the stated goal.
- Sectors most exposed: Most vulnerable sectors are social care, agriculture, hospitality and some sectors of the NHS supply chain.
- Highly Skilled Worker Visa salary threshold 2026: Salary rate of £41,700 per annum or “going rate” of the profession, whichever is greater.
- Employer costs: Employers pay a number of existing taxes that already apply in addition to payroll tax, such as sponsor licence fees, Immigration Skills Charge, visa fees and Immigration Health Surcharge.
How the UK Foreign Worker Tax Would Work Alongside Existing Rules
The employers already have to deal with a multi-layered tax system: PAYE tax system deductions, National Insurance contributions, and — in the case of sponsored employees — visa sponsorship costs that are linked to rules from the UK Home Office and HM Revenue and Customs. This wouldn’t be replaced by a new foreign worker tax for the UK; it would simply be added to it, making it the more expensive option to hire a foreign worker via a UK Skilled Worker Visa or other channel. Employer National Insurance is already a direct expense per employee; an extra layer on top of an existing foreign employee tax rules layer would be specific to the number of overseas employees.
Will Foreign Worker Tax Reduce Salaries?
For workers, calculation of direct take-home pay would probably not change instantly, as the tax will be viewed as an employer tax and not a wage cut. However, economists and business owners are concerned that the price of employing foreign workers may lead to indirect reductions in pay, hiring budgets or job availability – especially in sectors that are already thin on staff, such as care homes and farming.
Impact on Visas and Sponsor Licence Compliance
The UK foreign worker tax proposal comes alongside other changes to immigration salary thresholds and the UK work visa requirements by 2025–2026. The foreign worker levy would be in addition to the compliance costs already being faced by employers who have a sponsor licence and would make them less likely to continue to sponsor overseas workers, effectively reducing the number of workers available through legal means.
Ensuring job security for migrant workers.
The issue of job security for overseas workers already working in the UK is about the viability of their employers and not their visas. While existing UK tax residency rules and visa conditions for existing staff will not come into effect, smaller care providers and farms have voiced concern that this additional expense will result in their closures or staff freezes.
Comparison: Current System vs Proposed UK Foreign Worker Tax
| Cost Element | Current System (2026) | Under Proposed Foreign Worker Tax |
| Employer National Insurance | From staff: standard rate on all staff. | Standard rate (may be less for British staff) |
| Skilled Worker salary requirements | The minimum or the going rate is £41,700. | Unchanged means that the tax is added to the top of the bill. |
| Sponsor licence & Immigration Skills Charge | Included in the cost of each sponsored worker already. | A charge added to the existing charge. |
| Calculate the take-home pay for employees. | Usually based on the new PAYE + NI system | Likely unchanged directly |
| The cost to the employer for taking on an overseas employee. | This course includes a Visa, an NI, and a skills charge. | Add-on new tax, Visa, NI and skills. |
FAQs
Is the UK foreign worker tax law yet?
No. It is a political proposal and not existing legislation or HMRC policy.
Would it be applicable to every type of visa?
So far, proposals have been made for only some of the categories of the UK Skilled Worker Visa, and they generally concern lower-paid jobs.
Would the workers be willing to pay it directly?
No, it’s not a payroll deduction item that is deducted from workers’ pay; rather, it’s an employer charge deductible from employers’ earnings.
What are the areas of greatest concern?
The areas of care, agriculture and hospitality in which employers state that British applicants are rare for these positions.
Would it influence hiring in the future?
Maybe — foreign hiring costs may make employers wary of hiring overseas.
Does it alter the rules of UK tax residency?
No, there are no new residency/personal tax rules for migrant workers; those rules continue to be administered separately by HMRC.
