An investment-linked assurance plan (ILAP) — variously called an offshore investment bond, portfolio bond, unit-linked bond, or investment-linked insurance policy — is a single-premium life insurance policy that wraps a portfolio of investments. The insurance wrapper provides specific tax and estate planning advantages that, for internationally mobile high-net-worth individuals, can be highly valuable.
This guide explains how ILAPs work in practice, their advantages and limitations, the key jurisdictions from which they are issued, and the planning considerations most relevant to internationally mobile HNW clients.
Structure and Mechanics
An ILAP is a contract between the policyholder (often called the "life assured" or "assured") and an insurance company. The policyholder pays a single premium, which is invested by the insurer in a range of investments selected by the policyholder or their investment manager. The policy's value moves in line with the underlying investments.
The distinguishing feature is the insurance wrapper: unlike a direct investment in the same assets through a brokerage account, the assets are legally owned by the insurer. The policyholder has the economic benefit — the policy's surrender value equals the market value of the underlying investments — but does not directly own the assets.
This legal structure creates important consequences:
- Investment switches within the policy (changing from one fund to another, or from equities to bonds, or rebalancing the portfolio) do not create an immediate tax event for the policyholder. The policyholder is taxed on the policy's chargeable event gains — typically the difference between the surrender value and the premium paid, realised only on actual encashment, surrender, or certain other events
- The policyholder can withdraw a limited amount each year — typically 5% of the original premium, cumulative — without creating an immediate tax charge (under UK rules; this is described below in more detail)
- The policy is a single asset for estate planning and probate purposes, which can simplify administration on death
The 5% Withdrawal Allowance
Under UK tax rules (Income Tax (Trading and Other Income) Act 2005), policyholders of offshore life insurance bonds can withdraw up to 5% of the original premium per policy year on a cumulative, non-taxable basis. This means:
- In year 1, up to 5% can be withdrawn without a tax charge
- In year 2, if year 1 was unused, up to 10% can be withdrawn (or 5% in each year)
- Over 20 years, the full original premium can be withdrawn without creating an immediate chargeable event
This is not a tax exemption — the deferred amounts are ultimately taxed when the policy is encashed — but the deferral can have significant value, particularly for individuals who:
- Expect to be at a lower tax rate in future years (for example, after retirement)
- Expect to become non-UK resident and encash the policy in a lower-tax or zero-tax jurisdiction
- Want to manage their annual income carefully to avoid triggering higher or additional rate tax bands
The 5% allowance applies to each individual policy segment (most ILAPs are structured as multiple segments, or "clusters," rather than a single policy, giving additional flexibility to encash specific segments without encashing the whole bond).
Top-Slicing Relief
When an offshore bond is encashed and produces a chargeable event gain, UK income tax is charged on the full gain as if it were income in the year of encashment. This can create an unusually large income figure that pushes the policyholder into a higher rate band for that year only.
Top-slicing relief mitigates this "bunching" effect by spreading the gain over the number of complete years the policy was held, calculating the marginal rate applicable to the average gain per year, and applying that rate to the full gain. This reduces (but does not eliminate) the effective tax rate on large gains that have built up over many years.
For internationally mobile clients, the most important planning point is timing the encashment of an ILAP to coincide with:
- A year of non-UK residence (when no UK chargeable event tax charge may arise, depending on the treaty position)
- A year of relatively low UK-source income (maximising the effectiveness of top-slicing)
- A year after substantial tax reliefs or deductions reduce the individual's overall tax position
Portability for Internationally Mobile Clients
One of the principal advantages of an ILAP for internationally mobile clients is portability. Unlike a UK SIPP, which is a UK pension vehicle subject to UK rules, or a national insurance policy that may cease to be recognised on leaving the country, an offshore ILAP (issued from Jersey, Guernsey, Isle of Man, Ireland, Luxembourg, or similar jurisdictions) typically follows the policyholder across countries.
Most major offshore ILAP providers have a track record of paying benefits and handling policy queries for policyholders living in a wide range of countries. The tax treatment of the policy's income and gains in each country of residence is governed by that country's domestic rules and the applicable DTA; but the underlying policy remains intact and portable.
This contrasts with the position of a UK ISA, for example, which retains its UK tax advantage only while the holder is UK-resident. An ISA held by a non-UK-resident does not provide tax-free returns in the new country of residence.
Investment Universe
Within an ILAP, the available investment universe is typically very broad. Most offshore ILAP platforms allow access to:
- Thousands of UCITS and regulated funds across all asset classes
- Individual listed equities and bonds (through selected custodians)
- Alternative investments including hedge funds, private equity fund of funds, and real assets funds
- Cash accounts in multiple currencies
- Structured products
The policyholder typically appoints an investment manager (or, in some cases, manages the portfolio directly) to make investment decisions within the policy. The insurer acts as the legal owner of the assets; the investment manager acts under a discretionary or advisory mandate on behalf of the policyholder.
ILAP Jurisdictions
The principal ILAP issuing jurisdictions are:
- Isle of Man: home to major providers including RL360, Zurich International, and Friends Provident International. Isle of Man insurers are regulated by the Isle of Man Financial Services Authority and have access to the Insurance (Isle of Man) Act compensation scheme (covering 90% of liabilities)
- Guernsey: home to significant offshore insurance bond providers; regulated by the GFSC
- Jersey: regulated by the JFSC; some international insurers issue from Jersey
- Ireland: EU member state; Irish-domiciled bonds allow access to EU passporting and are subject to the Insurance Distribution Directive (IDD, in force since October 2018, which replaced the earlier Insurance Mediation Directive); particularly useful for EU-resident clients
- Luxembourg: another EU option; Luxembourg insurance bonds (assurance-vie luxembourgeoise) are widely used by French, Belgian, and EU-resident HNW investors and have a distinctive "super-privilege" creditor protection under Luxembourg law
The choice of jurisdiction affects the regulatory regime, the creditor protection provisions, the VAT and tax treatment of premiums, and the accessibility of the bond to investors in specific countries.
Creditor Protection
In some jurisdictions, the assets held within a life insurance policy enjoy specific protections from the policyholder's creditors. In Luxembourg, the "super-privilege" of policyholders means that their claim against the insurer ranks above all other creditors in an insolvency. This provides a meaningful layer of asset protection that is not available through a direct investment account.
Similar protections exist under Isle of Man and Guernsey law, though the precise scope and effectiveness varies and specialist legal advice should be taken where asset protection is a significant consideration.
Limitations and Considerations
Charges
ILAPs carry charges that direct investment accounts do not: a policy fee (sometimes called an administration charge), and potentially a bid-offer spread or initial charge on premium investment. For very large premiums and long-term investors, these charges may be modest in relative terms; for smaller amounts or shorter holding periods, they can be material. Transparency of charges has improved significantly since regulatory pressure in many jurisdictions, but careful scrutiny of the total cost of ownership (TCO) is essential.
Complexity
ILAPs are complex instruments. The chargeable event regime, the top-slicing calculation, and the interaction with the 5% withdrawal allowance require careful management. Many investors in ILAPs have made costly errors through misunderstanding the chargeable event rules, particularly when switching providers or consolidating policies. Professional management is strongly recommended.
Exit Charges
Some ILAP contracts include surrender penalties in the early years (typically the first five to ten years) if the policy is encashed before a minimum holding period. These should be checked carefully before committing.
