Investment Bonds & Assignment: A Clear Guide

1.  Why Investment Bonds Still Matter

Investment bonds sometimes get an unfair reputation because of historic mis‑selling — mainly due to high commissions before 2013.  Since the Retail Distribution Review (RDR), advisers must agree transparent, fixed fees with clients.  That change removed the “commission bias” and left us with what bonds actually are:

A flexible, tax‑efficient investment wrapper with powerful planning uses.

2.  Core Tax Features of Investment Bonds

Tax inside the bond

• The provider pays tax within the fund (life fund taxation).
• This covers corporation tax on profits and other internal charges.
• Because of this, you don’t pay Capital Gains Tax when you cash in segments.

5% tax‑deferred withdrawals

• You can withdraw up to 5% of your original investment each year for 20 years.
• These withdrawals are not immediately taxable.
• They don’t reduce age‑related allowances.

3.  The Real Power: Tax Planning Through Assignment

Assignment is the most under‑used feature of investment bonds.

What is assignment?

• You can change ownership of the bond (or individual segments).
• It is treated as a gift, not a disposal.
• Crucially: no Capital Gains Tax arises on assignment.
• The new owner is treated as if they held the bond from day one.

This creates huge tax‑planning opportunities.

4.  Assignment Between Spouses

If you are a higher‑rate taxpayer and your spouse is a basic‑rate taxpayer, you can assign the bond (or segments) to them.

When they encash:

• The gain is assessed against their tax position, not yours.
• If they remain within the basic‑rate band, no further tax is due.

Result: A simple, legitimate way to reduce or eliminate tax on bond gains.

5.  Assignment to Adult Children

This is where planning becomes extremely powerful.

Why adult children?

If your children are:

• At university
• Earning little or nothing
• Working part‑time
• Or simply early in their careers

…they may have unused personal allowance and basic‑rate band.

How it works

• You assign part of the bond to them.
• They encash it to fund:
• University fees
• Living costs
• House deposits
• Weddings
• Early‑career expenses

Provided the gain keeps them within the basic‑rate band (around £40k), no further tax is payable.

This is one of the most efficient ways to help children financially without triggering unnecessary tax.

6.  Planning for Your Own Retirement

Even if you’re a higher‑rate taxpayer today, you may become a basic‑rate taxpayer in retirement.

Holding a bond now means:

• You can defer encashment until retirement.
• Gains are then assessed at your future lower tax rate.

This makes bonds attractive for long‑term planning where income levels change over time.

7.  Bonds in Trust

Investment bonds also work extremely well with:

• Discretionary trusts
• Discounted gift trusts
• Loan trusts

Their structure makes them easy to segment, assign, and control — ideal for inheritance tax planning.

8.  Why Assignment Is So Valuable

Assignment allows you to:

• Move the tax liability to someone with a lower tax rate
• Avoid CGT entirely
• Support children in a tax‑efficient way
• Reduce tax on future encashments
• Integrate bonds into wider estate planning

It’s one of the most flexible tools available in UK tax planning.

9.  Professional Advice Is Essential

Assignment, segmentation, and trust planning can be complex.  Clients should always seek personalised advice to ensure:

• Correct ownership
• Correct tax treatment
• No unintended consequences

Comparison: Investment Bonds vs ISAs vs GIAs

Key Pointers for Comparison

Investment Bonds

Best when:

• You’re a higher‑rate taxpayer today but expect to be basic‑rate in retirement
• You want to assign gains to a spouse or adult child with a lower tax rate
• You need trust‑friendly planning (DGT, loan trust, discretionary trust)
• You want 5% tax‑deferred withdrawals without affecting allowances

This is the only wrapper that allows CGT‑free assignment, which is the real planning superpower.

ISAs

Best when:

• You want pure tax‑free growth and income
• You want simplicity and maximum flexibility
• You’re building long‑term wealth without trust or assignment needs

ISAs are unbeatable for simplicity, but they lack the advanced planning features of bonds.

GIAs

Best when:

• You want full investment flexibility
• You can use your CGT allowance each year
• You want to harvest gains/losses strategically

GIAs are the most flexible but the least tax‑advantaged.
