SOC 2421 is the occupation code covering chartered and certified accountants, and employers can sponsor workers into it under the Skilled Worker route provided the role meets the skill level, salary and genuine-vacancy requirements set for that code.
Who actually falls under this code
SOC 2421 is broader than the job title suggests. It captures qualified accountants working in financial accounting, management accounting, audit, tax and insolvency, including roles held by members of ICAEW, ACCA, CIMA, ICAS and equivalent bodies. It does not automatically cover bookkeepers, accounts assistants or unqualified finance administrators - those roles typically sit under a different, lower-skilled code and may not clear the Skilled Worker eligibility bar at all. Getting the code wrong on the Certificate of Sponsorship is one of the more common errors Home Office caseworkers flag, so job descriptions and duties need to genuinely match the accountancy-professional level, not just the job title on offer.
Practice, in-house and secondment models
SOC 2421 sponsors show up in two quite different settings: accountancy practices sponsoring auditors, tax advisers or client managers, and corporates or public bodies sponsoring an in-house financial or management accountant. The eligibility test is the same, but the risk profile differs. A practice firm sponsoring several accountants across different client engagements needs to be especially careful that each sponsored worker is doing the firm's own genuine role rather than being effectively supplied to a client on a contracted-out basis - the FAQ below on multi-client work covers this directly. Secondments to a client site are sometimes acceptable where the employment relationship, supervision and genuine business need remain with the sponsoring firm, but a pattern that looks like staff leasing rather than employment is one of the more scrutinised arrangements in professional services sponsorship. Insolvency work sits inside 2421 as an occupation, but an individual actually acting as a licensed insolvency practitioner holds a separate authorisation from a recognised professional body on top of any accountancy qualification, and sponsors in this niche should check both are current - a lapsed insolvency licence is a distinct problem from a lapsed accountancy membership.
Salary: going rate, not just the floor
Every occupation code carries its own published going rate, and 2421 is no exception - the figure is set separately from the general Skilled Worker salary floor and both thresholds have to be met. Employers sometimes pay the general floor and assume they are compliant, without checking whether the going rate for 2421 specifically sits higher. Before issuing a CoS, check the current going rate against the eligible occupations and codes list on GOV.UK, and see Annaizu's guides on the salary floor and going rates by occupation for how the two interact, including how part-time hours and allowances are, and are not, counted.
Qualification evidence sponsors need on file
Because 2421 is a professionally regulated field, a right-to-work check alone is not sufficient assurance. Sponsors should verify and retain evidence of the individual's accountancy qualification or professional body membership alongside the standard immigration checks, since a Home Office compliance visit can ask why a role coded as a qualified accountant is held by someone with no verifiable qualification. This sits on top of, not instead of, the record-keeping duties set out in the Home Office's Appendix D record-keeping guidance. Firms managing multiple sponsored accountants often find that tracking qualification documents, visa expiry and CoS details in spreadsheets breaks down quickly - a centralised document record with renewal alerts reduces the risk of a lapsed check surfacing at the wrong moment.
Membership lapses don't stay hidden
Professional body membership isn't a one-off check done at hiring and then forgotten. ICAEW, ACCA, CIMA and equivalent bodies require annual subscription renewal and, in most cases, evidence of continuing professional development, and a lapsed membership can happen quietly - an administrative oversight, a missed renewal invoice - without anyone noticing until it surfaces at exactly the wrong moment, such as during a compliance visit or a client due-diligence request. Firms sponsoring several accountants are better placed to catch this if membership renewal dates sit in the same system as visa expiry and CoS renewal dates, rather than being tracked separately by whichever manager happens to remember. This is exactly the kind of gap a mock audit run before a real inspection tends to catch, particularly at firms that have grown their sponsored headcount faster than their internal record-keeping.
FAQs
Does a trainee or part-qualified accountant fit SOC 2421? Not reliably - the code is aimed at qualified accountancy roles, so a trainee working toward ACCA or ACA exams may need assessing against a different code depending on actual duties and seniority; misclassifying this is a compliance risk, not just an administrative one.
Can an accountancy firm sponsor someone across multiple clients? The worker must be doing the sponsoring employer's own genuine role; placing a sponsored accountant with third-party clients on a contracted-out basis raises the same third-party labour issues covered under general sponsor duties guidance, and firms should check this before assuming a placement model is compliant.
Does a newly qualified accountant on a lower starting salary meet the going rate? Possibly - the Skilled Worker route allows a reduced going rate for genuine new entrants to the labour market, such as those within a set number of years of gaining their qualification, but the discount has specific eligibility conditions of its own and doesn't apply simply because someone has recently qualified.
