    Returning to the UK — SRT, s.10A Catch-Up, FIG Regime, ISA + Property Mechanics

    Returning to the UK triggers SRT re-application from the return year. Split-year arrival cases 4-8 may apply. The 5-year temporary non-residence catch-up (TCGA 1992 s.10A) may apply if you return within 5 full tax years — gains realised during non-residence on pre-departure assets wash back into year of return. The 4-year FIG (Foreign Income + Gains) regime is available if you've been non-UK-resident for 10+ tax years.

    In plain English

    Coming back to the UK reopens UK residence under SRT. Split-year cases 4-8 may give you part-year non-resident treatment for the year of return. If you've been non-resident for fewer than 5 full tax years, the s.10A catch-up may pull gains realised during non-residence back into the year of return (on assets you held BEFORE leaving). If you've been non-resident for 10+ full tax years, the 4-year FIG regime offers a temporary shelter for foreign income and gains. UK property held throughout: rebasing date for CGT depends on the regime — for residential the April 2015 NRCGT rebasing remains. ISAs retain their wrapper protection while you're abroad (no contributions allowed during non-residence, but existing investments continue tax-sheltered for UK tax purposes); contribution rights resume on UK residency. UK pensions resume normal UK tax treatment.

    How it works

    SRT on return — Automatic UK Tests + Sufficient Ties + split-year cases 4-8

    Apply SRT to the return year. If you pass an Automatic UK Test (183 days, only-home, full-time UK work) you're UK-resident. Otherwise Sufficient Ties Test using arriver thresholds (different from leaver thresholds — generally more generous day-count allowances). Split-year cases 4-8 (Schedule 45 Part 3): • Case 4: starting to have a UK home • Case 5: starting full-time work in UK • Case 6: ceasing full-time overseas work • Case 7: partner of someone ceasing full-time overseas work • Case 8: starting to have a UK home (different facts pattern) Multiple cases can apply; priority order matters. Claim split-year via SA109 box 3.

    5-year temporary non-residence catch-up (s.10A) on return

    Triggered if all of: • UK-resident in 4+ of the 7 pre-departure tax years • Return to UK residence within 5 FULL tax years of becoming non-resident (the split-year departure year doesn't count as a full year for this purpose) • Gains realised during non-residence on assets held BEFORE leaving Mechanics: gains treated as accruing in the year of return; taxed at that year's CGT rates; using that year's AEA. NRCGT-regime UK property gains already taxed under NRCGT are NOT caught (carve-out to prevent double-charge). Clean exit: 5 full UK tax years non-resident before returning. People who left mid-2020/21 (split-year departure) need to remain non-resident through to at least 6 April 2026 to clear the s.10A risk on pre-departure UK shares/portfolio gains.

    4-year FIG regime — eligibility + claim mechanics

    FA 2025. Available to UK residents who were non-UK-resident in each of the 10 tax years immediately preceding the year they become UK-resident. Offers full exemption from UK income tax on foreign income + UK CGT on foreign gains for 4 consecutive tax years from arrival (or election in subsequent years within the 4-year window). Claim via SA — annual election. Once 4 years elapse, normal UK tax treatment resumes on worldwide income + gains. Bringing FIG-sheltered income into UK during the 4 years remains UK-tax-free (no remittance-basis trap of old regime). Key limitation: ONLY for fresh arrivers post-10-year-non-residence. Existing UK residents at 6 April 2025 transitioning off remittance basis have separate transitional relief (rebasing to April 2017 MV on certain assets + temporary repatriation facility TRF for past unremitted income at favourable rate).

    ISA, property, pension drawdown on return — practical mechanics

    ISAs: wrapper preserved during non-residence; no new contributions while non-resident; resumption of contribution rights on UK residency restored. Returns within wrapper UK-tax-sheltered throughout. UK property held throughout: residential rebasing to April 2015 MV remains the default NRCGT base; on return, normal UK CGT applies to post-rebasing gain on subsequent disposal. PPR relief mechanics resume on actual occupation. UK pension drawdown: normal UK tax treatment resumes on UK-residency restoration. Any tax-relieved pension contributions made while non-resident (e.g. limited £3,600 gross annual relief for non-relevant-UK-income individuals during first 5 years post-departure) credited as basis. QROPS transfers made pre-return: 5-year UK overseas-transfer-charge tax tail per PTM112000 continues regardless of return date.

    Common mistakes + traps

    Worked example

    Priya returns to UK April 2030 after 4 years 6 months in Singapore — UK share disposals during non-residence

    Priya left UK October 2025 (Case 1 split-year). Non-resident 2026/27, 2027/28, 2028/29, 2029/30 (4 full tax years). Returns 6 April 2030 — UK-resident from start of 2030/31. She sold UK AIM portfolio in 2027/28 realising £80k gain; UK Singapore-sourced consulting income £150k/year while abroad.

    1. Step 1 — Full tax years non-resident: 2026/27 through 2029/30 = 4 full years. Less than 5. s.10A catch-up triggered.
    2. Step 2 — Pre-departure asset test: UK AIM portfolio held pre-October-2025 = pre-departure asset.
    3. Step 3 — s.10A wash-back: £80k gain treated as accruing in 2030/31 return year. Taxed at 2030/31 CGT rates (assume 24% higher-rate residential / 20% other). Less AEA 2030/31. £80k - £3k = £77k @ 20% = £15,400.
    4. Step 4 — Singapore consulting income abroad: NOT UK source while non-resident, NOT UK-taxable on return (out of UK scope at the time).
    5. Step 5 — FIG eligibility check: non-resident 4 full years — less than 10. FIG NOT available.
    6. Step 6 — Return year SA: split-year Case 5 (starting full-time UK work) or Case 4 (starting UK home) likely applies. SA109 claims split-year + reports £80k washed-back gain.

    Outcome: Priya owes ~£15,400 UK CGT in 2030/31 on AIM gain realised during non-residence — s.10A catch despite gain being realised + taxed in Singapore at the time. To avoid this she would have needed to remain non-resident for the full 2030/31 tax year (5 full years post-departure). Singapore tax already paid on the £80k gain may qualify for Foreign Tax Credit under UK-Singapore DTA against the UK CGT liability — check treaty.

    How this connects to the rest of the framework

    Statutory Residence Test →

    Return-year SRT analysis uses the same Schedule 45 framework — arrival cases 4-8 mirror leaver cases 1-3.

    NRCGT + temporary non-residence →

    s.10A catch-up mechanics for UK shares + non-property assets — NRCGT regime carved out to avoid double-charge.

    April 2025 IHT reform + LTR →

    FIG regime sits in IT/CGT space — independent of LTR IHT test. Returning to UK starts LTR clock for IHT.

    UK source income (non-resident) →

    On return, UK source income reverts to normal UK-resident treatment; disregarded income s.811 mechanics no longer apply.

    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.
    Can I claim the 4-year FIG regime on returning to the UK?+
    Only if you've been NON-UK-resident in each of the 10 tax years immediately preceding the year you become UK-resident. So you need a full decade outside the UK before the FIG regime opens. Available for 4 consecutive tax years from arrival (or first 4 elected within the window). Annual election via SA. Foreign income + foreign gains arising during the FIG window exempt from UK IT/CGT — remittance to UK during the window also tax-free.
    I returned after 6 tax years — do I still face s.10A catch-up?+
    No. s.10A requires return within 5 FULL tax years of becoming non-resident. The split-year departure year doesn't count as a full year for this purpose. 6 full tax years non-resident = clean exit on s.10A risk for pre-departure asset gains. UK property NRCGT regime is separate — those gains were already taxed under NRCGT 60-day reporting at the time of disposal.
    What happens to my ISA when I return to the UK?+
    Wrapper preserved throughout non-residence — your existing ISA investments continued growing UK-tax-sheltered. On UK residency restoration: contribution rights resume from the tax year you become UK-resident. You can subscribe up to the annual limit (£20,000 in 2025/26) for that year and onward. Any contributions made while non-resident were invalid but typically rectified by the provider — check with your ISA manager. Existing balances + investment returns within the wrapper are unaffected.
    How does returning interact with my IHT position?+
    Returning to UK residence restarts the LTR clock. Your historic UK residence (pre-departure) counts toward the 10/20 LTR test, plus new UK residence years from return. If you were LTR pre-departure with a tail running, the tail effectively pauses (you're back in UK residence so LTR status reattaches). Worldwide IHT scope re-engages from the year of return. Specialist STEP-affiliated advice warranted for high-net-worth returning estates — the transition mechanics around partial-year IHT events + trust regime are complex.
