Business Investment Relief and IHT: How Non-Doms Can Remit Funds and Reduce Inheritance Tax
Business Investment Relief allows non-UK domiciled remittance basis users to bring overseas income and gains into the UK without a remittance charge — if invested in a qualifying trading business within 45 days. When that investment also qualifies for BPR, the funds are outside the IHT estate after two years.
BIR Qualifying Investments: What Qualifies?
| Investment Type | Qualifies for BIR? | Notes |
|---|---|---|
| Shares in a qualifying trading company | Yes — if company is unlisted (or listed on AIM/NEX) and is a trading company or holding company of a trading group | Shares must be newly issued to the investor. Cannot be purchase of existing shares from third party for BIR (though existing shares may separately qualify for BPR). |
| Loan to a qualifying company | Yes — if loan is used wholly for the purposes of a qualifying trade | The loan must be a commercial loan at arm's length. Zero-interest or artificially structured loans may not qualify. |
| Investment in a qualifying partnership | Yes — if partnership carries on a qualifying trade | Partner must have real involvement. Purely passive limited partnership interests require analysis. |
| Loan to a qualifying partnership | Yes — subject to same conditions as company loans | Must be used for trade purposes. |
| Investment via SEIS/EIS | Yes — EIS and SEIS companies are qualifying investments for BIR | Double benefit: BIR on remittance + income tax relief + CGT exemption + BPR for IHT after 2 years. |
| Residential property investment | No — property letting/development is not a qualifying trade for BIR | Property investment is excluded from BIR (as it is from BPR). Must be an active trading business. |
| Listed company shares (main market) | No — quoted securities not qualifying under BPR rules | BIR requires the same underlying qualifying investment test. Listed companies fail this. |
BIR + BPR Timeline
Remit foreign income/gains to UK bank account
BIR clock starts — 45-day window to invest
Invest in qualifying unquoted trading company shares (or qualifying loan)
Must be completed within 45 days. Investment is not a taxable remittance.
BPR two-year qualifying period satisfied
The BIR investment is now also outside the IHT estate (100% BPR). Both the remittance deferral and the IHT exemption are active.
Monitor: company must remain qualifying; investor must not trigger extraction events
Annual review recommended. Consider reinvestment on disposal to roll BIR deferral.
Deemed domicile reached — no new BIR investments available
Existing BIR investments continue. No new remittance basis use. Forward planning essential before Year 15.
Frequently Asked Questions
What is Business Investment Relief and how does it work?
Business Investment Relief (BIR) was introduced by Finance Act 2012 (now codified at s809VA–VC ITA 2007). It allows a non-UK domiciled individual who is taxed on the remittance basis to bring foreign income and gains into the UK and invest them in a qualifying business without triggering the normal remittance basis tax charge. Without BIR, remitting offshore income or gains to the UK crystallises income tax or CGT on those amounts. With BIR, the remittance is not a taxable remittance if the money is invested within 45 days of arrival in a qualifying investment — the charge is deferred until the investment is extracted (and even then, only if the extraction is a 'trigger event'). The policy rationale was to encourage non-dom wealth into UK business investment: the UK gets economic activity and employment; the non-dom gets to use their overseas funds in the UK without immediate tax. From an IHT perspective, if the BIR investment qualifies for Business Property Relief (BPR) — which many unquoted trading company shares do — the same funds are also outside the IHT estate after two years.
What are the qualifying conditions for Business Investment Relief?
The BIR qualifying conditions under s809VB ITA 2007 are: (1) The remitted funds must be invested in a 'qualifying investment' — shares or loans in a trading company or partnership, where the company/partnership carries on a qualifying trade (not property investment, holding company of a property business, or financial trading). (2) The investment must be made within 45 days of the funds being remitted to the UK. (3) The company must be an unlisted UK-incorporated company at the time of investment (AIM and NEX-listed companies qualify as 'unlisted' for BIR purposes). (4) The investor must not have pre-existing shares in the company at a level that would cause the company to fail the independence test. (5) The investor must not take artificially structured loans or arrangements that amount to extracting value without a trigger event. The rules are detailed and require specialist tax advice — HMRC has published extensive guidance at RDRM33100 onwards.
What happens when BIR funds are extracted from the investment?
Extraction of BIR funds triggers a 'relevant event' which causes the deferred remittance to crystallise — the original foreign income or gain is treated as remitted at that point and becomes taxable. Extraction events include: (1) disposal of the BIR shares or loan; (2) the company ceasing to qualify (e.g. it becomes listed on the main market or ceases to trade); (3) the investor receiving a benefit that amounts to extracting value. However, there are important exemptions: if the disposal proceeds or repaid loan are reinvested in another qualifying BIR investment within 45 days, there is no trigger event — the BIR deferral rolls over. Similarly, if the company is acquired by another qualifying company in an approved reorganisation, BIR can continue. HMRC has 4 years from the trigger event to assess the deferred remittance. Careful extraction planning — rolling investments, using approved reorganisations, timing disposals — can extend the deferral indefinitely for a long-term investor.
How does Business Investment Relief interact with Business Property Relief for IHT?
BIR and BPR are separate reliefs but create a powerful combination for non-domiciled investors. BIR defers the remittance basis charge on the investment capital — so no income tax or CGT arises on bringing the funds to the UK. BPR (under s105 IHTA 1984) removes qualifying unquoted trading company shares from the IHT estate after two years' ownership. The combined effect is: (1) Foreign income or gains remitted under BIR are not immediately taxable. (2) The BIR investment (unquoted trading company shares) qualifies for 100% BPR after 2 years — not in the IHT estate. (3) The individual has effectively converted untaxed offshore funds into a UK business investment that is also IHT-free. This combination is particularly valuable for high-net-worth non-doms who have substantial unremitted foreign income from investment portfolios, rental income, or business profits. Note: from April 2026, BPR is capped at £2.5m for qualifying assets above that threshold — but this does not affect the BIR mechanism itself.
How does the April 2017 deemed domicile reform affect BIR planning?
The Finance (No.2) Act 2017 substantially changed the deemed domicile rules: from 6 April 2017, non-doms who have been UK-resident for 15 of the previous 20 tax years become deemed domiciled for all UK tax purposes (income tax, CGT, and IHT). Once deemed domiciled, the individual can no longer use the remittance basis — their worldwide income and gains are taxable on the arising basis. Since BIR is only available to remittance basis users, deemed domicile extinguishes the ability to make new BIR investments. However: (1) Existing BIR investments made before deemed domicile was reached continue to benefit from the BIR deferral — they are not crystallised by the change in domicile status. (2) Extractions after deemed domicile that are trigger events will crystallise the original deferred remittance — but taxed on the arising basis going forward, so the pre-deemed-domicile foreign funds are the only remaining BIR benefit. (3) From the IHT perspective, an existing BIR investment that qualifies for BPR remains outside the estate after deemed domicile — domicile status does not affect BPR. Planning: non-doms approaching 15 years' UK residence should review BIR investments and consider the overall tax position before deemed domicile applies.
Are EIS and SEIS investments good BIR vehicles?
EIS (Enterprise Investment Scheme) and SEIS (Seed EIS) investments can be excellent BIR vehicles because they typically meet all the BIR qualifying conditions — they are shares in unquoted UK trading companies making genuine equity investments in growth businesses. The combined reliefs available are substantial: (1) BIR: no remittance basis charge on the invested capital. (2) EIS income tax relief: 30% income tax relief on the investment amount (up to £1m or £2m for knowledge-intensive companies per tax year) — though this requires UK income tax liability (remittance basis users can claim this only against UK-source income). (3) EIS CGT exemption: disposal after 3 years is free of UK CGT. (4) EIS loss relief against income. (5) BPR: qualifying EIS shares in unquoted trading companies are eligible for 100% BPR after 2 years — outside the IHT estate. The main constraint is that EIS income tax relief requires a UK income tax liability — high-earning non-doms who pay limited UK income tax on the arising basis may not be able to utilise this. But BIR and BPR work together regardless of the income tax position.
