What you need to know about top slicing relief: how it works and more

  • Top slicing relief can assist in reducing the rate of tax charged on bond gains by applying a spreading mechanism
  • 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
  • This article reflects changes announced in the 11 March 2020 Budget

Why use top slicing relief

In our articles UK Investment Bonds: taxation facts and Taxation of Offshore Policies article we explained that chargeable event gains are treated as forming the highest part of total income in a top slicing relief calculation. The relief can assist in reducing the rate of tax charged on bond gains by applying a spreading mechanism. Please see also Top Slicing Relief planning.

With regard to basic/higher rate taxpayers, the implications of the Scottish Rate of Income Tax (SRIT) need to be addressed for Scottish taxpayers. SRIT applies to non-savings and non-dividend income with the personal allowance and thresholds and taxes on savings and dividends remaining a UK ‘reserved’ matter. The higher rate threshold for Scottish taxpayers is below the threshold in the rest of the UK. Nevertheless, given that the Scottish Parliament can only set the rates and the limits for non-savings and non-dividend income, then for savings, dividends and capital gains, it is necessary to ignore the Scottish threshold and refer to the UK limit instead.

Top slicing relief is generally available where the taxpayer would be liable to tax at a lower rate were it not for the inclusion of the chargeable event gain in their income for the year. When the chargeable event gain does not move a taxpayer into a higher tax rate, there may be still be some top slicing relief available due to the effect of the personal savings allowance nil rate and the starting rate for savings. The amount of these allowances available in the top slicing relief calculation is set by virtue of the taxpayer’s adjusted net income.

The Personal Savings Allowance and the Starting Rate for Savings

The starting rate for savings and the personal savings allowance nil rate should be taken into account when calculating top slicing relief, where applicable.

The starting rate for savings is available to those taxpayers with total non-savings income of less than their personal allowance plus £5,000.

The personal savings allowance nil rate is applied to the first £1000 of savings income for basic rate taxpayers, and the first £500 for higher rate taxpayers.

The amount of these allowances available in the top slicing relief calculation is set by virtue of the taxpayer’s adjusted net income, so they are not adjusted when calculating the notional tax due on the ‘sliced gain’.

Reduced Personal Allowances

For an individual whose adjusted net income exceeds £100,000, the amount of the personal allowance available to them in that tax year is reduced accordingly in accordance with ITA07/PT3/CH2/S35(2).

In the Budget of 11 March 2020, measures were announced allowing the personal allowance to be reinstated within the calculation for top slicing relief where it has been reduced by reason of including a gain in the individual’s income for the year. For this purpose, the personal allowance is to be calculated by reference to the taxpayer’s other income and the relevant slice. It was announced that the measure has effect for all relevant gains occurring on or after 11 March 2020.

The position before 11 March 2020 is that where the personal allowance has been reduced, it is that reduced figure which is used in the top slicing calculation.

See below for further information and examples.

The measures were included in Finance Bill 2020 published on 19 March 2020. At the time of writing, the Bill has not gained Royal Assent and become an Act.

How spreading works

The key to a top slicing calculation is to divide the gain by the number of complete years. HMRC use 'N' to denote the number of complete years. 'N' which can never be less than one is calculated as follows:

 

Onshore

Offshore

Previous rule

Excess event period back to commencement, or for 2nd and later events, back to the last excess gain

Excess event period always back to commencement

Rule change in FA13

  • If time apportionment relief (TAR) does NOT apply the period is still back to  last excess gain, BUT
  • If time apportionment relief applies then for 2nd and later events, the period is back to commencement for reporting purposes.

As per s552(5)(e) ICTA 1988 the insurer will assume TAR does NOT apply for reporting.

  • If time apportionment relief (TAR) does NOT apply the period is now back to last excess gain,
    BUT
  • If time apportionment relief applies then for 2nd and later events, the period is back to commencement for reporting purposes.

HMRC confirmed non-UK insurers can assume TAR applies for reporting unless explicitly told TAR will not be claimed.

Full surrender

Always back to the commencement

Always back to commencement

Note that an ‘excess event’ arises on a part surrender or a part assignment. 

The Finance Act 2013 (FA 13) brought in updates to the chargeable events legislation in respect of time apportionment relief (TAR) to include onshore policies as well as offshore. Essentially, TAR was extended to policies issued by UK insurers on or after 6 April 2013 and to existing policies issued by UK insurers which are modified on or after that date. FA 2013 amended Section 536 (2) ITTOIA 2005 which  is a section dealing with top slicing rules. Under TAR, the chargeable gain may be reduced for tax purposes if the beneficial owner was not UK resident throughout the policy period. TAR applies by virtue of S528 ITTOIA 2005.

The effect of these changes on calculation events for UK resident individuals holding offshore policies who have been UK resident throughout is therefore as follows:

 Pre 06/04/13 policies

  • Number of top slicing years equals number of years since inception.

Policies made on or after 06/04/13 (or earlier policies varied etc. on or after that date)

  • Number of top slicing years equals number of years since previous event.

For those UK residents who have not been UK resident throughout such that TAR applies, then the number of years used remains the period back to commencement but that figure will be reduced to reflect periods of overseas residence.

Top slicing relief calculation

HMRC adopt a five step procedure as follows:

Step 1: Calculate the total taxable income for the year and identify how much of the gain falls within the starting rate for savings, personal savings allowance nil rate, basic, higher or additional rate bands as appropriate. Any gift aid payments must be disregarded both in this computation and in the remaining steps below.

Step 2: Calculate the total tax due on the gain across all tax bands. Deduct basic rate tax treated as paid* to find the individual's liability for the tax year. 

Step 3: Calculate the annual equivalent of the gain. The annual equivalent is calculated by dividing the gain by N (see earlier).

Step 4: Calculate the individual’s liability to tax on the annual equivalent. For gains arising on or after 11 March 2020, the personal allowance is recalculated where appropriate. The amount of the savings starting rate and personal savings allowance used in the top slicing relief calculation are set by virtue of the taxpayer’s adjusted net income for the tax year. They are not adjusted to calculate the notional tax due on the ‘sliced gain’. Deduct basic rate tax treated as paid* on the annual equivalent and multiply the result by N. This gives the individual's relieved liability.

Step 5: Deduct the individual's relieved liability at step 4 from the individual's liability at step 2 to give the amount of top slicing relief due.

*Note: Basic rate tax is also deducted for offshore bonds for the purposes of the top slicing calculation.

There is a worked example for both onshore and offshore bonds later in this article.

When part of the gain falls into additional rate

Top slicing relief is not just available to mitigate a higher rate liability arising on a chargeable event gain but is also available to mitigate an additional rate liability. In 2020/21, individuals with adjusted net income in excess of £150,000 are subject to additional rate tax of 45% on the excess (38.1% dividend additional rate).

There is a worked example where part of the gain falls into additional rate later in this article.

Two or more chargeable event gains the same tax year

In this case, the total gains are added together. The 'annual equivalent' is calculated separately for each gain, and then these annual equivalents are added together.

Example

£12,000 gain on Bond A arisen over four years. Annual equivalent = £3,000
£30,000 gain on Bond B arisen over six years. Annual equivalent = £5,000

Total gains = £12,000+£30,000 = £42,000.
Total annual equivalent = £3,000+£5,000 = £8,000.
Top slicing factor (N) = £42,000/£8,000 = 5.25 years. 

When top slicing relief doesn't apply

Top slicing relief is available to mitigate a higher rate or additional rate income tax liability arising as a result of a chargeable event gain being added to the taxpayer's total income. It does not:

  • Reduce income for the purposes of child or working tax credits (instead the full amount of the gain is included).
  • Reduce income below £100,000 to preserve full entitlement to the personal allowance.
  • Apply to personal representatives, corporate's or trustees. However, for the avoidance of doubt where a gain arises on a trust held policy and the creator is chargeable then that person would be eligible for top slicing relief. In contrast, where the creator is deceased or non resident and the trustees are non resident then a UK beneficiary receiving a benefit from the trust is taxable on that amount - if so, top slicing relief is not available.
  • Apply to annual gains that arise on 'personal portfolio bond events.'

Self Assessment

HMRC Helpsheets 320 and 321 help investors fill in the relevant boxes in their tax return for gains on UK life insurance policies and foreign life insurance policies respectively. The Helpsheets are available from HMRC

Gains on UK policies are inserted into the 'Additional information' pages of the tax return. The full amount of the gain should be returned together with the number of complete years. This information is available from the chargeable event certificate issued by the insurer. If the individual is due any top slicing relief it will then be automatically calculated using the information provided.

Gains on foreign policies are inserted into the 'Foreign' pages of the tax return. A chargeable event certificate might not be available showing the gain if the policy was taken out before 6 April 2000, and for later policies the reporting requirements are not as onerous as those for UK policies. Nevertheless it remains the responsibility of the investor to report gains under self assessment principles.

Example of top slicing relief for an onshore bond

Anne has a taxable salary in tax year 2020-2021 of £35,900 (after personal allowances) and a chargeable event gain of £24,000 on the surrender of an investment bond that she had held for just over eight years. The basic rate band for 2020-21 is £37,500.

Her tax liability for 2020-21 before top-slicing relief is:


Salary (after personal allowance)

£35,900

Chargeable event gain

£24,000

 

£59,900

Tax @20% on £35,900

£7,180

Tax @ 0% on £500 (PSA) 

£0

Tax @ 20% on £1,100

£220

Tax @ 40% on £22,400

£8,960

Total liability

£16,360

Calculation of Relief 

Step one

Anne's taxable income (including the chargeable event gain) is £59,900. The gain falls within the different tax bands as follows:

PSA - £500 @ 0%

Basic Rate Band - £1,100 @ 20%

Higher Rate Band - £22,400 @ 40%

Step two

The total tax due on the bond gain across all tax bands is £9,180

The tax treated as paid on the gain is £24,000 @ 20% = £4,800

The individual’s liability for the tax year is therefore £9,180 - £4,800 = £4,380

Step three

The 'annual equivalent' of the gain £24,000 / 8 = £3,000.

Step four

The 'annual equivalent' + taxable income = £3,000 + £35,900 = £38,900.

The total tax on the slice is (£500 @ 0%) + (£1,100 @ 20%) + (£1,400 @ 40%) = £780

The tax treated as paid on the slice is £3,000 @ 20% = £600

The individual’s tax relieved liability is (£780 - £600) multiplied by “N”. In this “N” case is 8 years so the tax relieved liability is £1,440

Step five

Top slicing relief = £4,380 – £1,440 = £2,940

Summary

Anne's liability after top-slicing relief is £16,360 - £2,940 = £13,420

The basic rate credit is £24,000 @ 20% = £4,800.

The overall liability is reduced to £13,420 - £4,800 = £8,620

Example of top slicing relief for an offshore bond

If we took the last example of Anne, but instead the bond had been offshore, the above five steps would be identical.

Anne's liability after top slicing relief would be £16,360 - £2,940 = £13,420

There is no reduction in her liability since no basic rate credit is due for an offshore bond.

Example of top slicing relief for an onshore bond with additional rate tax due

Bridgit has a taxable salary in tax year 2020-2021 of £32,500 and a chargeable event gain of £160,000 on the surrender of an onshore bond on 1 June 2020 that she had held for just over eight years.

Her total income is greater than £100,000 so the basic personal allowance is reduced to zero, but reinstated at Step 4.

Her tax liability for 2020-21 before top-slicing relief is:


Salary

£32,500

Chargeable event gain

£160,000

 

£192,500

Tax @ 20% on £32,500 

£6,500

 

 

Tax @ 20% on £5,000

£1,000

Tax @40% on £112,500

£45,000

Tax @45% on £42,500

£19,125

Total liability

£71,625

Calculation of Relief

Step one

Bridgit's taxable income (including the chargeable event gain) is £192,500. The gain falls within the different tax bands as follows:

Basic Rate Band - £5,000 @ 20%

Higher Rate Band - £112,500 @ 40%

Additional Rate Band - £42,500 @ 45%

Step two

The total tax due on the bond gain across all tax bands is £65,125

The tax treated as paid on the gain is £160,000 x 20% = £32,000

The individual’s liability for the tax year is therefore £65,125 - £32,000 = £33,125

Step three

The 'annual equivalent' of the gain £160,000 / 8 = £20,000

Step four

In this step, we add Bridgit’s salary of £32,500 to the £20,000 slice to give us a notional adjusted income of £52,500. As this figure is below £100,000 the full personal allowance will be reinstated, in this step only. As detailed later in the article, her personal allowance must be set against her salary in preference to the gain.

With regard to the salary, £12,500 is taxed at 0% within the personal allowance. The balance of £20,000 is taxed at 20%. The bond slice of £20,000 will then be taxed as follows.

The total tax on the slice is  (£17,500 @ 20%) + (£2,500 @ 40%) = £4,500

The tax treated as paid on the slice is £20,000 @ 20% = £4,000

The individual’s relieved liability is (£4,500 - £4,000) multiplied by “N”. In this “N” case is 8 years so the tax relieved liability is £4,000.

Step five

Top slicing relief = £33,125 – £4,000  = £29,125

Further thoughts on 11 March 2020 Budget

When calculating top slicing relief, the starting rate for savings and the personal savings allowance must be considered. The amount of these ‘allowances’ is set by the individual’s adjusted net income. They are not recalculated in step 4 when calculating the notional tax due on the slice.

In contrast, where an individual has adjusted net income over £100,000 and their personal allowance is reduced then the position for gains arising on or after 11 March 2020 is that the reduced personal allowance is recalculated for the purposes of Step 4 of the top slicing relief calculation only.

Budget 2020 also confirmed that within the calculation of top slicing relief, reliefs  and allowances available must now be set-off, as far as possible, against other income in preference to the gain. This means that the rules comprised in S25(2) of ITA 2007 do not apply – these rules require reliefs and allowances to be set against income in a way that results in the greatest reduction in an individual’s income tax liability.

Example

Fraser has salary of £25,000 and on 1 July 2020 he surrenders a bond held for 10 years with a gain of £100,000.

  • His adjusted net income of £125,000 reduces his personal allowance to nil.
  • His starting rate for saving is nil (because the first £5,000 of taxable income is earned income).
  • His personal savings allowance is £500 (because he is a higher rate taxpayer).
  • For the purposes of Step 4 of the top slicing relief calculation his personal allowance is recalculated to £12,500 (because his £25,000 salary plus bond slice of £10,000 falls well below £100,000).
  • His personal savings allowance is not recalculated within Step 4 of his top slicing relief calculation. Instead it remains at £500.
  • His non entitlement to the starting rate for savings is also not recalculated within Step 4.
  • His recalculated personal allowance must be set as far as possible against other income (i.e. his salary) in preference to his bond gain

The Finance Bill states that the above amendments have effect for 2019/20 and subsequent tax years. The amendments do not have effect for 2019/20 or 2020/21 in the case of an individual who is only liable for chargeable event bond tax on gains from one or more chargeable events which occur before 11 March 2020.
