TL;DR
The Immigration Skills Charge is paid by sponsors for each Certificate of Sponsorship issued on the Skilled Worker and certain other work routes. This article explains who pays, how much, the reductions for small businesses and charities, and the exemptions.
Key facts
- The ISC is paid by sponsors, not workers, and is non-refundable in most cases.
- The standard rate is per year of sponsorship requested; reduced rates apply to small businesses and charities.
- Exemptions apply to PhD-level SOC codes, intra-company transfers and some specific routes.
- The ISC is charged at the time of CoS assignment in the Sponsor Management System.
What the ISC is and why it exists
The Immigration Skills Charge was introduced to encourage employers to invest in training the UK workforce rather than hiring from overseas. It applies to sponsors of Skilled Worker and Senior or Specialist Worker (and historically some other routes) and is paid when the CoS is assigned to the worker.
The receipts go to the UK Treasury and are described as funding skills development, though the income is not formally ring-fenced. The charge has been increased since introduction and is part of the overall cost of sponsoring international workers.
Rates and reductions
The standard rate is set per year of sponsorship requested on the CoS. Small businesses (those meeting the small company definition under the Companies Act 2006) and charities (registered with the Charity Commission or equivalent) pay a reduced rate per year. The reduction has been around 60-70% of the standard rate historically.
A 5-year CoS at the standard rate represents a substantial cost per sponsored worker before any application fees the worker pays. Small business and charity rates are correspondingly lower. Current rates are published on GOV.UK and reviewed periodically.
Exemptions
Several exemptions apply: PhD-level SOC codes (where the role is at the highest skill level), some intra-company transfers under the Senior or Specialist Worker route in specific circumstances, sponsoring workers who were previously on a Student visa applying to switch in-country (with conditions), and some other narrow categories.
Each exemption requires the sponsor to confirm the basis on the CoS and may be subject to compliance check. The cost saving of an exemption can be substantial for multi-year sponsorships.
When the ISC is paid
Payment is made at the time of CoS assignment through the Sponsor Management System. The CoS cannot be assigned until the ISC is paid. The fee is for the full requested period of sponsorship; partial payments are not permitted.
Refunds are available in narrow circumstances: visa refusal, CoS not used within the validity window, or other defined situations. Where the worker leaves the sponsor's employment partway through the sponsorship, the unused portion of the ISC is not refunded.
Practical implications
The ISC is part of the sponsor's hiring cost calculation. Some sponsors pass it on to the worker contractually (typically through a clawback if the worker leaves early), though the Home Office's view is that the ISC is the sponsor's responsibility and should not be borne by the worker.
Sponsors planning long sponsorships have a meaningful upfront cost. Small businesses and charities can find the cost particularly challenging at the standard rate; the reduced rate exists partly to address this. Budget planning for sponsorship includes the ISC, the CoS fee, the licence fee, and the indirect costs of HR compliance.
Rates and how the charge is calculated
Standard rate: per year of sponsorship requested on the CoS, for medium and large sponsors. The annual rate is set by the Immigration Skills Charge Regulations and updated periodically. For a 5-year CoS at the standard rate, the total ISC is paid in a single transaction at CoS assignment.
Reduced rate: for small businesses (defined under the Companies Act 2006 small company size criteria) and charities (registered with the Charity Commission or equivalent regulator). The reduced rate is approximately 60-70% of the standard rate. Substantial savings over multi-year sponsorships.
Calculation: the rate per year multiplied by the years of sponsorship requested. Partial years are typically rounded up. The total is paid at CoS assignment, not spread across the visa period.
Comparison with other sponsor costs: the ISC is typically the largest single sponsor cost per worker. A 5-year CoS at the standard rate has substantial ISC. The CoS fee itself is much smaller. The Immigration Health Surcharge is the worker's responsibility (not the sponsor's).
Exemptions from the ISC
PhD-level SOC codes: specific SOC codes at the highest skill level (RQF 8 equivalent) are exempt from the ISC. The exemption is per CoS and claimed by the sponsor on the CoS assignment. The Home Office publishes the eligible SOC codes; common examples include certain academic researcher roles and senior research positions.
Intra-company transfer route: Senior or Specialist Worker under Appendix Global Business Mobility has specific ISC exemptions in defined circumstances. The exemption depends on the worker's prior employment with the sponsor group and the role's nature.
Switching from Student route: workers switching in-country from Student to Skilled Worker can be exempt from ISC in some circumstances. The exemption supports the policy of retaining international graduates in the UK workforce.
Other narrow exemptions: certain niche categories are exempted by specific provisions. The Immigration Skills Charge Regulations and accompanying guidance cover all current exemptions.
Payment, refunds and accounting treatment
Payment at CoS assignment: the ISC must be paid before the CoS can be assigned. Payment is through the SMS using sponsor's payment card or bank transfer. The CoS becomes available for use after payment is confirmed.
Refunds: available in defined circumstances. Visa refusal triggers full ISC refund. CoS not used within the 3-month validity window triggers full refund. Sponsorship granted for shorter period than requested triggers proportionate refund.
No refund where worker leaves the sponsor early: where the worker leaves the sponsor's employment partway through the sponsorship period, the unused portion of the ISC is not refunded. The sponsor's commercial risk; some sponsors include clawback provisions in employment contracts where the worker resigns within a defined period.
Accounting treatment: in financial reporting, sponsors typically expense the ISC as an HR cost in the period of payment. The full upfront payment can affect cash flow planning for multi-year, multi-worker sponsorship programmes. Tax treatment varies; corporation tax deduction is typically available for ISC as a sponsor employment cost.
Strategic considerations for sponsors
Time on the Skilled Worker route counts towards 5 years of continuous lawful residence for ILR under Appendix Skilled Worker, with permitted absences capped at 180 days in any rolling 12-month period. Changes of employer within the route do not reset the clock as long as continuous sponsored employment is maintained.
Switching to Health and Care Worker, Senior or Specialist Worker, or Scale-up routes can preserve the continuous-residence count under Appendix Continuous Residence. Switching to Global Talent (with endorsement at Exceptional Talent level) can shorten total time to settlement to 3 years from the Global Talent switch point.
British citizenship by naturalisation under the British Nationality Act 1981 requires 12 months of ILR (or sooner for spouses of British citizens with 3 years' UK residence), the standard residence test with the absence cap, B1 English (typically met for ILR), Life in the UK test (also typically met for ILR), and the good character requirement assessed under Home Office guidance.
Sponsor budgeting and ISC strategy
Annual budgeting: sponsors estimate the number of CoS to issue each year and budget the ISC accordingly. For a sponsor issuing 10 Skilled Worker CoS at the standard ISC rate for 5 years each, the annual budget for ISC alone is substantial.
Small business and charity rate: where applicable, the reduced rate halves or more the per-CoS ISC. Sponsors should confirm their size band at licence renewal to ensure the correct rate is applied.
Coordinating with HR practices: some sponsors include the ISC in the overall cost of international hires reported to senior leadership. Others present it as a separate immigration line item. Both are reasonable; the cost is real either way.
PhD-level SOC exemption: sponsors with research-intensive workforces may have many sponsored workers in PhD-level SOC codes. The exemption can reduce the ISC budget substantially.
Clawback considerations: where workers leave the employer before the end of the sponsored period, the ISC is not refunded. Some sponsors include clawback clauses in employment contracts; the Home Office's view is that the ISC is the sponsor's cost and should not be passed to workers.
Sponsor records and ongoing compliance
Document organisation: a structured folder system (physical or digital) for immigration documents reduces friction across the years of the visa. Categories: identity (passports, BRPs, eVisa records), employment (CoS, payslips, employer letters), finances (bank statements, tax returns), relationships (where applicable), education (where applicable), travel (boarding passes, hotel receipts).
Digital preservation: scan and back up all documents to secure cloud storage. Multiple backups (separate cloud, USB drive, family member's copy) protect against loss. Encryption is sensible for sensitive documents (tax records, financial statements).
Long-term retention: documents from the visa period are needed at extension, ILR, and potentially naturalisation. Keep documents for at least 6 years after the visa period; immigration records are often referenced years later.
Records during the qualifying period: from day one of the initial visa, track UK presence and absences for the eventual settlement calculation. Travel logs, employer travel records, and supporting evidence all build the documentary picture.
Long-term planning across the immigration journey
Long-term planning across the visa lifecycle: the journey from initial visa to ILR to British citizenship spans 6-8 years typically. Building the documentary record, maintaining lawful status, planning extensions and switches, and the eventual settlement application all benefit from a long-term view.
Career and family planning around immigration: visa requirements interact with career progression, education choices, family timing, and other life decisions. Where significant life events are planned, considering the immigration position is part of the planning.
Risk management: keep documents, maintain contact with UKVI through changes of address, comply with visa conditions, build a clean record. Issues that arise during the visa years are easier to address proactively than at the settlement application.
Backup routes: where the primary route encounters difficulties, alternative routes provide options. Skilled Worker holders can consider Global Talent, family route, Innovator Founder depending on circumstances. Long Residence (10 years) provides a backup settlement path.
Future return scenarios: where the applicant may return to the country of origin or move elsewhere, planning preserves options. Maintaining country-of-origin ties, financial records, and qualifications supports future flexibility.
Frequent practical questions about UK immigration
What if my application is delayed? UKVI publishes service standards on GOV.UK. Most cases are decided within the published standard; complex cases can take longer. Contact UKVI's helpline after the standard time has expired. Formal complaints through the dedicated channel can prompt review.
What if I cannot afford the fee? Fee waivers are available on family route, human rights, and some other immigration applications where destitution or child welfare is affected. The MN1 fee waiver application is on GOV.UK; specialist support from charities helps with the evidence.
What if I need specialist advice? OISC-regulated advisers handle most immigration matters at the appropriate level. Solicitors authorised under the Solicitors Regulation Authority handle complex cases including Tribunal appeals and judicial review. Legal aid is available for some matters.
What about appeals and challenges? Refusals carry route-specific remedies. Most points-based routes have administrative review for caseworker errors. Family route human rights refusals have Tribunal appeal rights. Judicial review applies where no other remedy exists.
What if circumstances change? Visa conditions and the surrounding circumstances can change. Reporting material changes (address, employer, family circumstances) to UKVI through the UKVI account or formal change of circumstances applications maintains the visa's integrity.
What about future return to the country of origin? UK immigration status does not prevent eventual return; the leaving-the-uk articles on this site cover the tax and practical aspects of departure.
