    Business Owner Moving Abroad → CMC + corporate residence

    Central Management and Control + UK Corporate Residence + TCGA 1992 s.185 Exit Charge

    A UK-incorporated company is UK-resident for tax purposes under CTA 2009 s.14 — regardless of where its directors live — UNLESS a double tax agreement allocates residence to another state under a treaty tie-breaker (CTA 2009 s.18). The common-law 'central management and control' (CMC) doctrine from De Beers Consolidated Mines Ltd v Howe [1906] AC 455, confirmed in Wood v Holden [2006] EWCA Civ 26, asks WHERE the highest level of management and control is actually exercised — usually the board. If the dominant director relocates abroad and effectively makes board decisions from there, the company can become dual-resident, then non-UK-resident under the DTA tie-breaker (typical 'place of effective management' test), triggering a TCGA 1992 s.185 deemed disposal of chargeable assets at market value — often a six-figure CGT/CT liability on goodwill, IP, property, and shareholdings.

    In plain English

    Two tests stack. First, under UK domestic law (CTA 2009 s.14), a UK-incorporated company is UK-resident — full stop. Second, common law adds a CMC test that asks where the highest level of strategic management actually happens. If your UK Ltd Co board is now 'really' meeting from Dubai or Sydney because you (the dominant director) moved there, the company is dual-resident: UK by incorporation, foreign by CMC. When the company is dual-resident, the relevant DTA's tie-breaker (typically 'place of effective management' — POEM — Article 4(3) OECD Model) usually allocates residence to one state only. If that state is the foreign one, CTA 2009 s.18 makes the company non-UK-resident for UK tax purposes, even though it stays on the UK companies register. The moment UK residence ceases, TCGA 1992 s.185 deems the company to have sold all its chargeable assets at market value and immediately reacquired them. The chargeable gain falls into the company's final UK CT period. A company with £600,000 of unrecognised goodwill or IP value can trigger a corporation tax bill in the £100,000s overnight. The Exit Charge Payment Plan (ECPP) lets you instalment the tax — but only if you move to an EEA state. Post-Brexit moves to the USA, UAE, Australia, etc. get no instalment relief. Practical takeaway: if you intend to retain the UK Ltd Co AND move abroad, you must either (a) keep CMC unambiguously in the UK (UK-resident chair + UK board meetings + UK strategy + UK minutes), or (b) plan the exit charge before you go, or (c) strike off the UK Ltd Co (DS01) before departure if there are no chargeable assets of consequence.

    How it works

    The two-tier test — incorporation then CMC

    CTA 2009 s.14 makes any UK-incorporated company UK-resident. CMC is the common-law residence test that applies in addition for non-UK-incorporated companies — and crucially, for the DTA tie-breaker when a UK-incorporated company is also resident elsewhere under that country's domestic law (e.g. by management). When both apply, the DTA Article 4(3) tie-breaker (in most UK treaties post-2017 BEPS, this is decided by mutual agreement procedure; older treaties use 'place of effective management'). CTA 2009 s.18 then translates that DTA outcome into UK domestic non-residence.

    De Beers + Wood v Holden — what CMC actually means

    De Beers (1906): a London-registered company carrying on diamond mining in South Africa was held UK-resident because the board met in London and took the substantive strategic decisions there (despite operational management being in Kimberley). Lord Loreburn LC: 'a company resides… where its real business is carried on; and… the real business is carried on where the central management and control actually abides'. Wood v Holden (2006): the Court of Appeal distinguished a Netherlands-resident company (ABN-AMRO trustee) whose board genuinely considered transactions, even when proposals came pre-packaged from UK advisers, from a rubber-stamping board where control 'really' sat with someone abroad (the UK adviser). Critical practical question: are the directors making genuine decisions, or merely signing what someone else (you, abroad) has decided?

    TCGA 1992 s.185 exit charge mechanics

    On the day immediately before UK residence ceases, the company is treated as having disposed of all chargeable assets (other than those held for a UK PE that continues — see s.185(4)) at market value and immediately reacquired them at that value. Chargeable assets include: land, buildings, goodwill, intellectual property, shares (subject to substantial shareholding exemption SSE conditions), and certain debts. The resulting chargeable gain enters the company's final UK CT computation. There is no rollover for the migration itself. SSE (Sch 7AC TCGA 1992) can shelter qualifying share disposals; capital losses can offset gains. Trading losses carry forward to the foreign-resident company only to the extent it continues a UK PE.

    ECPP — Exit Charge Payment Plan (EEA only post-Brexit)

    FA 2019 Sch 11 + TMA 1970 Sch 3ZB allow the exit charge to be paid in 6 equal annual instalments (with interest) where the company migrates to an EEA state. The EEA-only restriction is the post-Brexit cliff edge — moves to the USA, UAE, Australia, Singapore, Switzerland, etc. attract full immediate payment of the exit charge alongside the normal CT due date (9 months + 1 day after the period end). Election must be made on the migration return; failure is irreversible.

    Common mistakes + traps

    Worked example

    Alex, sole director and 100% shareholder of Alex Consulting Ltd (UK-incorporated), £600,000 internally-built goodwill, moves to Dubai 1 September 2026 retaining the company to continue invoicing UK clients

    Alex Consulting Ltd has built £600,000 of goodwill over 8 years (£0 base cost). Alex relocates personally to Dubai 1 September 2026, takes a UAE residence visa, and intends to keep running the UK Ltd Co from Dubai (calling UK clients from his Dubai home, invoicing through the UK company, paying himself dividends).

    1. Step 1 — Domestic UK position: under CTA 2009 s.14 the company stays UK-resident by incorporation regardless of Alex's move.
    2. Step 2 — UAE Corporate Tax position: under Federal Decree-Law 47/2022 the company has UAE Corporate Tax residence if it is 'effectively managed and controlled' in the UAE. With the sole director directing the company day-to-day from Dubai, the UAE FTA would generally regard the company as UAE-managed and therefore UAE-resident.
    3. Step 3 — Dual residence + UK-UAE DTA 2016: Article 4 tie-breaker — 'place of effective management' (POEM). On the facts (sole director, all strategic decisions from Dubai, no UK board substance), POEM is in the UAE. CTA 2009 s.18 then makes the company UK non-resident for the period from 1 September 2026.
    4. Step 4 — TCGA 1992 s.185 deemed disposal: on 31 August 2026 (day immediately before residence ceases) the company is deemed to dispose of its goodwill at market value (£600,000) and reacquire at £600,000. Chargeable gain £600,000 (no base cost). Corporation tax @ 25% (FY2026 main rate, assuming taxable profits > £250,000 lower limit) = £150,000.
    5. Step 5 — No ECPP available: Dubai is not an EEA state, so the full £150,000 is payable with the final UK CT period — 9 months and 1 day after the period end. Alex has no liquid cash in the company to pay; he must either fund a director's loan (which becomes a s.455 charge if outstanding 9 months later) or refinance personally.
    6. Step 6 — Alternative if planned: retain genuine UK CMC. Appoint UK-resident chair + UK strategy director, run quarterly UK board meetings (in person), document strategic decisions made in UK. Operational invoicing from Dubai is administrative, not management. This preserves UK residence and avoids s.185 — but creates risk of UAE PE for the UK Ltd Co (see /business-owner-moving-abroad/pe-risk-and-treaty-mechanics).
    7. Step 7 — Alternative if pre-departure planning: extract goodwill in the UK Ltd Co before departure via BADR-eligible share sale or members' voluntary liquidation (MVL). BADR rate 14% from 6 April 2025; 18% from 6 April 2026. £600,000 gain @ 14% = £84,000 (vs £150,000 exit charge) — saving £66,000 with proper planning.

    Outcome: Unplanned move = £150,000 immediate corporation tax exit charge with no instalment relief. Planned MVL + BADR pre-departure = £84,000 personal CGT (with deferral options). Genuine UK CMC retention = no exit charge but ongoing PE risk in UAE. The unplanned 'just keep running it from Dubai' route is the most expensive by a margin.

    How this connects to the rest of the framework

    PE risk + treaty mechanics →

    Maintaining UK CMC does not necessarily prevent foreign PE — the director's foreign home office can still create taxable presence in the destination state.

    Director's fees + close co. dividends →

    Close-company shareholder-director dynamics interact with CMC analysis — the dominant director's location is often decisive.

    8 scenarios →

    Scenarios 1-4 (SaaS USA, consultant UAE, tradesperson AU, healthcare Ireland) all turn on CMC + exit charge decisions.

    UAE-specific application of CMC + exit charge for SME directors moving to the UAE under the UAE Corporate Tax June 2023 regime.

    /moving-abroad/srt →

    The director's own UK SRT residence is a separate test — but a non-resident dominant director making decisions from abroad is the trigger for the company-residence analysis.

    Frequently asked questions

    What happens if I miss the Self Assessment deadline?+
    The Self Assessment deadline is 31 January (online filing) for the previous tax year. Miss it and HMRC apply an automatic £100 penalty. Beyond that: £10 per day from 3 months late (capped at £900), 5% of tax due at 6 months late, and another 5% at 12 months late, under Schedule 55 of the Taxes Management Act 1970. If you have a genuine reason (serious illness, bereavement, technical issue with HMRC's systems) you can appeal with evidence; HMRC accepts reasonable excuse appeals in most genuine cases.
    Do I need an accountant or can I file Self Assessment myself?+
    Legally you can file Self Assessment yourself via gov.uk for free, most simple sole-trader returns (single income source, basic expenses) are realistic to self-file. An accountant adds real value when: your trading profit is above £40,000 (extraction-strategy decisions matter), you have multiple income streams (PAYE + self-employment + property + dividends), you've crossed the £90,000 VAT threshold, you're considering incorporation, or you have an HMRC enquiry. Expect to pay £400-£1,500/year for a typical sole-trader accountant; the cost is itself a deductible expense.
    How do payments on account work?+
    When your Self Assessment tax bill exceeds £1,000 for the first time, HMRC requires payments on account toward NEXT year's tax. Half the current bill is due 31 January (alongside the current bill); the other half is due 31 July. So your first January after crossing the threshold can hit with a double-bill: last year's balance + first payment on account. Adjust via Form SA303 if you expect next year's income to drop substantially. Payments on account don't apply if more than 80% of your tax is collected via PAYE.
    If I appoint a UK-resident director, does that fix CMC?+
    Not automatically. Wood v Holden requires the directors collectively to genuinely make decisions. A nominee or 'paper' director who rubber-stamps decisions made by the foreign-resident shareholder will not preserve CMC. The board must have substantive deliberation, access to information, and the ability (and demonstrated practice) of declining or modifying proposals. Quarterly UK board minutes that record decisions made by you abroad do not help.
    Does the DTA tie-breaker always allocate to one state only?+
    Older OECD-model treaties use 'place of effective management' as a sole criterion. Post-2017 BEPS Action 6 the recommendation is to resolve dual residence by competent authority mutual agreement procedure (MAP), with no treaty residence until agreed. Recent UK treaties (e.g. UK-UAE 2016 Article 4) often still use POEM. Check the specific treaty article.
    Can I avoid s.185 by transferring assets to a UK-resident newco before the migration?+
    Intra-group transfers (TCGA 1992 s.171) work on a no-gain-no-loss basis only between UK-resident group members. If the receiving company is also migrating, s.185 still bites. Pre-departure restructuring can work in specific fact patterns but requires careful clearance with HMRC (and triggers anti-avoidance scrutiny under GAAR + TAAR).
    What if there are no significant chargeable assets in the company?+
    If the company is a pure-services Ltd Co with no goodwill on the balance sheet, no IP, no property, no shares of value, the s.185 charge may be minimal. But HMRC's view of 'goodwill' under s.185 includes internally-built reputation and customer base value (not just balance-sheet goodwill). For a long-established consultancy with recurring clients, a valuation exercise is essential before assuming the charge is nil.
