Questions from advisers answered on the effect of the chargeable event gain on personal allowance.


Q: What is the £100,000 threshold?

A: This threshold was introduced in the 2010/11 tax year. The personal allowance reduces where adjusted net income exceeds £100,000, by £1 for every £2 of income above the £100,000 limit.

Q: Is there a minimum that the personal allowance can be reduced to?

A: No, it is possible to wipe it out entirely

How it works

Q: How does it work in practice?

A: Firstly, add the whole gain to the other income to calculate the individual’s adjusted net income. If this is above £100,000, then work out the individual’s reduced personal allowance – it is reduced by £1 for every £2 over the threshold. Adjusted net income of at least £125,000 will wipe out the personal allowance altogether (Tax Year 2019/20).

Next, work out the individual’s higher rate threshold by adding the reduced personal allowance to the basic rate tax threshold. If the personal allowance is reduced, then an individual will reach the higher rate tax band earlier than normal. For example, in the tax year 2019-20, the normal personal allowance is £12,500 and the basic rate threshold is £37,500, therefore a person can earn £50,000 before hitting the higher rate tax band. An individual who has lost all of their personal allowance will have a higher rate threshold of the basic rate band, i.e. £37,500.*

Interaction with top slicing relief

Q: There should be top slicing relief though, shouldn’t there? The top sliced Chargeable Event Gain didn’t breach the £100,000 threshold.

A: When you are looking at the impact of a chargeable event gain, you need to remember to add the WHOLE (not top sliced) Chargeable Event Gain to the client’s other income to see if the £100,000 threshold has been exceeded. So whilst there may be top slicing relief on the tax due, top slicing cannot be used to reduce the impact on Personal Allowance.

Q: Where does top slicing relief come into it?

A: Chargeable event gains can mean that a basic rate taxpayer can be pushed into the higher rate band or a higher rate taxpayer can be pushed into the additional rate band. Top slicing relief can assist in reducing the rate of tax charged and minimising the effect of the gain.

For a full surrender of an onshore or offshore bond, always top slice by the number of complete years back to commencement.

Where there is an ‘excess event’ such as a part surrender gain then the rules are more complex. 

Effect on Tax Position

Q: Will there be any tax to pay?

A: Although there would be no further tax liability on a Chargeable Event Gain for an onshore bond which is assessed at basic rate, there may still be basic rate tax due. Other forms of income, such as salary within the personal allowance, would no longer be tax free because there is no personal allowance available. This would normally be taxable at basic rate.

Q: My client is a basic rate taxpayer. Will they have higher rate tax to pay if they lose their personal allowance?

A: Perhaps - it depends how much, if any, of the personal allowance is lost and if the top sliced gain takes them into the higher rate tax band.
