If you earn over £100,000 in any tax year your personal allowance is gradually reduced by £1 for every £2 of adjusted net income over £100,000 irrespective of age. This means that any taxable receipt that boosts your income over £100,000 will result in a reduction in personal tax allowances. Accordingly, your personal Income Tax allowance would be reduced to zero if your adjusted net income is £125,140 or above.

Your adjusted net income is your total taxable income before any personal allowances, less certain tax reliefs such as trading losses and certain charitable donations and pension contributions.

For the current tax year if your adjusted net income is likely to fall between £100,000 and £125,140 you would pay an effective marginal rate of tax of 60%.

If your income sits within this band you should consider what financial planning opportunities are available in order to avoid this personal allowance trap by reducing your income below £100,000. For example, by giving gifts to charity, increasing pension contributions and participating in certain investment schemes.

A higher rate or additional rate taxpayer who wanted to reduce their tax bill could make a gift to charity in the current tax year and then elect to carry back the contribution to 2022-23. A request to carry back the donation must be made before or at the same time as the 2022-23 Self-Assessment return is completed and filed, i.e., by 31 January 2024.

The annual exempt amount applicable to Capital Gains Tax (CGT) has been reduced to £6,000 (from £12,300) for the new 2023-24 tax year.

CGT is normally charged at a simple flat rate of 20% and this applies to most chargeable gains made by individuals. If taxpayers only pay basic rate tax and make a small capital gain, they may only be subject to a reduced rate of 10%. Once the total of taxable income and gains exceed the higher rate threshold, the excess will be subject to 20% CGT.

A higher rate of CGT applies to gains on the disposal of residential property (apart from a principal private residence). The rates are 18% for basic rate taxpayers and 28% for higher rate taxpayers.

Most people are aware that they do not usually have to pay CGT when they sell their qualifying residential property used wholly as a main family residence. However other sales of property that are not a principle private residence (PPR) will be subject to CGT.

This includes:

• buy-to-let properties
• business premises
• land
• inherited property

The deadline for paying any CGT due on the sale of a residential property is 60-days. This means that a CGT return needs to be completed and a payment on account of any CGT due should be made within 60-days of the completion of the transaction. This applies to UK residents selling UK residential property where CGT is due.

There are various reliefs available from CGT for the sale of qualifying business assets.
