Many people focus on inheritance tax (IHT) when planning their estate, but there is another potential tax bill that is often overlooked: income tax on investment bonds after death.
Investment bonds are popular, particularly among retirees, because they allow investors to withdraw up to 5% of their original investment each year without an immediate tax charge. However, the tax is not avoided forever, it is usually deferred until the bond is fully or partially cashed in.
Unlike shares or savings accounts, investment bond growth is not normally taxed each year. Instead, any gain is treated as income tax, not capital gains tax, when the bond is surrendered.
This can create a large tax bill because many years of growth may become taxable in a single tax year. For example, someone who has taken regular withdrawals over many years could face a significant taxable gain when the remaining bond is eventually cashed in.
One of the lesser-known rules is that investment bonds are treated as being fully surrendered in the year of death. This means any accumulated gains can become taxable as income on the deceased's final tax return. This can push income into higher tax bands and may reduce the benefit of top slicing relief, potentially creating an unexpected tax bill for the estate!
There are ways to manage the risk, including:
- Gradually surrendering parts of the bond over several years.
- Using the 5% withdrawal allowance strategically.
- Keeping taxable income within lower tax bands where possible.
Investment bonds can be useful financial planning tools, but they require careful tax planning later in life to avoid an unnecessary income tax charge.
