How Capital Gains Tax On Property Will Change From April 2020

capital gains tax

Summary. Starting from April 2020, taxpayers must pay capital gains tax (CGT) on residential property sales within 30 days of completion, marking a significant departure from the current self-assessment system. This rule applies to both UK and overseas properties, with penalties for non-compliance. Thomas Nock Martin offers expert advice on navigating these changes.


In April 2020, some important changes to the tax regime for gains made from the sale of residential property will come into effect. Here is a short summary of how they will affect the way you report and pay capital gains tax


Capital gains tax: currently

Current HMRC rules state, capital gains tax made by individuals should be reported through self-assessment. This means, for example, if you sell a property between 6 April 2019 and 5 April 2020 you must declare it on your tax return and pay any owing tax before 31 January 2021. However, from 2020/21 new rules will apply, which outline that tax payable on certain types of gain will be due up to 21 months sooner. 


The rule change

From 6 April 2020, CGT incurred following the sale of a residential property will have to be paid within 30 days of the completion date. Failure to comply with these changes will result in HMRC imposing interest and potential fines. This new deadline applies even when there has been no money exchange, such as when transferring a property into a trust or gifting it to a family member.

Keep up to date

Recently, HMRC published a report that highlights a lack of proper awareness among those likely to be affected by the capital gains tax changes regarding the new rules. HMRC is now taking steps to ensure that taxpayers become aware of these changes. Customers who will face the greatest risk are those dealing with a ‘one-off’ property transaction who may have had little, or no, exposure to CGT.  “Multiple disposal’ customers, on the other hand, are more likely to have a better understanding and deeper knowledge of capital gains tax on property. They are also more likely to seek advice from a professional. 


Tighter deadlines

Taxpayers must pay tax for gains made from the sale of residential property both in the UK and overseas starting from 6 April 2020. And, capital gains tax on property following the sale will have to be paid within 30 days of the completion date. You will need to submit a provisional calculation of the gain and pay the estimated tax due. You should still declare the capital gains on your self-assessment tax returns by the usual self-assessment deadline. Additionally, you should pay any CGT due over and above your provisional (estimated) payment.

If you are not in the self-assessment system, you still need to abide by the 30-day declaration and payment rules. However, you do not need to register for this sole purpose. You may review your provisional calculation and pay any differences after the tax year in which you incurred a capital gains tax.


Estimating capital gains tax

In order to calculate your provisional CGT bill you’ll need to estimate your yearly taxable income to determine how much capital gains tax is payable at 18% and how much at 28%.

Some advice: By bringing forward capital losses from earlier years and those made in the same year as the gain you will be able to reduce the gain liable for tax (up until when you make your estimated calculation). 

It’s also worth noting that if you intend to sell assets which will make a loss, for example, shares, it is beneficial to make the transaction before you make a gain reportable under the 30-day rule. This allows you to take the loss into consideration when calculating your provisional payment.

No amendments

The above information is important because once you submit your provisional calculation and pay the tax, you cannot reduce it. So if for example, you made a capital loss later in the year, you wouldn’t be able to claim the tax back until you submit your self-assessment return or year-end review. HMRC also intend to distribute penalties for errors and anyone who does not meet the 30-day deadline for reporting a gain and paying the tax.

In discussion

The new ruling on capital gains tax coincides with the changes to Private Residence Relief (PRR). Although still under consultation it is likely that from April 2020, this relief will apply to the full period a taxpayer lived in the property as their principal residence plus the final 9 months of occupancy. This is down from 18 months (and 36 in 2014).

This means there will be more taxpayers liable for CGT and so subject to the new 30-day changes. To reiterate, if you make a capital gain from selling a residential property that incurs tax liability, you must submit and pay the estimated tax calculation to HMRC within 30 days of completion.
