What is Offshore Investment Bond?
A life assurance investment wrapper issued outside the UK where growth rolls up gross, with UK tax deferred until a chargeable event occurs.
Full Definition
An offshore investment bond is a life assurance wrapper issued by an insurer based outside the UK -- commonly Ireland, Isle of Man, or Luxembourg. The key advantage over an onshore bond is that investment growth inside the wrapper rolls up gross: there is no internal tax charged within the policy (unlike onshore bonds, which pay a notional equivalent of basic-rate tax internally). This allows significant compounding advantages for higher and additional-rate taxpayers who can afford to leave the money invested for many years without withdrawing. UK resident policyholders do not pay UK tax until a chargeable event occurs: full or partial surrender, death of the life assured, assignment for money or money's worth, exceeding the 5% cumulative annual withdrawal allowance, or policy maturity. On a chargeable event, the gain is assessed to income tax in the policyholder's hands in the year the event occurs. Crucially, there is no deemed basic-rate tax credit for offshore bonds (unlike onshore bonds), so the full gain is subject to income tax at the policyholder's marginal rate. Time apportionment relief under ITTOIA 2005 s.528 can reduce the assessable gain proportionally for years of non-UK residence during the policy's life. Top-slicing relief under ITTOIA 2005 ss.535-537 can spread the gain across the years the bond was held, potentially keeping the effective rate within the basic-rate band. Offshore bonds are widely used in IHT planning when held in discretionary trusts, as investment vehicles for non-UK domiciled individuals, and for deferred tax planning by high earners approaching or in retirement. Investors should be aware that provider solvency protection arrangements differ from UK FSCS coverage, so choosing a financially strong and well-regulated insurer is important.
