What is an offshore investment bond?
An offshore investment bond, also referred to as an international portfolio bond, is a tax-efficient wrapper that lets you invest a lump sum — typically £250,000 or more — in a wide range of investment funds (could be UK, EU or international) without incurring annual UK tax on growth or capital gains on fund sales. Your investment compounds without any tax drag until you choose to draw from your offshore bond beyond an annual 5% allowance. This is called gross roll-up.
Offshore bonds are issued by life assurance companies based in jurisdictions such as the Isle of Man, Ireland, or Guernsey, and are thus outside of the UK tax net during the accumulation phase. When you take money out (beyond the annual 5% accumulated allowance), a tax event is triggered, but by that point you may be in a lower tax bracket, or able to use relief mechanisms to significantly reduce the bill. You may have also gifted underlying sub-policies to other family members, which is not a chargeable event.
For UK residents and families, UK expats, returning residents, and internationally mobile professionals, offshore investment bonds can be one of the most powerful long-term wealth structures available. All well and good, however offshore investment bonds are considerably more complex than a simple General Investment Account, and therefore the wrong structure, or a poorly advised withdrawal, can be potentially costly and tax inefficient. That is why specialised, independent advice matters. I have advised on the use of offshore investment bonds for more than 20 years and have become highly specialised in how they can be used within wider wealth planning and succession strategies.
