This page only contains information about the Capital Gains Tax service, available at https://www.tax.service.gov.uk/calculate-your-capital-gains/non-resident.

Using this service

The Capital Gains Tax calculator lets you work out the amount payable to HMRC for resident and non-resident Capital Gains Tax. This is the tax on your profit when you sell items like property or shares that have increased in value.

This service is run by HM Revenue and Customs (HMRC). We want as many people as possible to be able to use this service. This means you should be able to:

  • change colours, contrast levels and fonts
  • zoom in up to 400% without the text spilling off the screen
  • get from the start of the service to the end using just a keyboard
  • get from the start of the service to the end using speech recognition software
  • listen to the service using a screen reader (including the most recent versions of JAWS, NVDA and VoiceOver)

We have also made the text in the service as simple as possible to understand.

AbilityNet has advice on making your device easier to use if you have a disability.

How accessible this service is

This service is partially compliant with the Web Content Accessibility Guidelines version 2.2 AA standard.

Some people may find parts of this service difficult to use:

  • On the service timeout, the page heading is used to alert screen-reader users about the timeout, and as a result it is not recognised as a heading by screen readers.
  • On several pages, the hint text relating to the question has not been set up correctly with each radio button. This means it will be read multiple times by screen readers when it’s not relevant.
  • On the ‘Capital Gains Tax to pay for 2026/27’ page, there are duplicated headings read out by screen readers which may confuse users as it does not match the page’s visual hierarchy.
  • On several pages, user-entered information is deleted when navigating backward and forward through the service. This means users will have re-enter the information.
  • On pages where the user enters monetary amounts, the input box has not been labelled correctly by the ‘£’ symbol, instead of the question label for assistive technology.
  • The first question page times out after 15 minutes when there’s no activity. It does not give users the opportunity to extend their session which may be disorientating as they are unexpectedly taken to a service timed out page and have to start again.
  • When validation is triggered on the ‘private residence relief’ page, there is no error summary. This means users may have a harder time identifying the problem.
  • Several pages display error messages that do not identify the problem correctly. This means users may struggle to correct them.

HMRC is committed to making this service accessible, in accordance with the Public Sector Bodies (Websites and Mobile Applications) (No. 2) Accessibility Regulations 2018.

This service is partially compliant with the Web Content Accessibility Guidelines version 2.2 AA standard, due to the non-compliances listed below.

Non‐accessible content

The content listed below is non-accessible for the following reasons.

Non‐compliance with the accessibility regulations

On the service timeout page the H1 has been given the role of alert which overrides the heading role. This fails WCAG 2.2 success criterion 1.3.1 Info and Relationships. This will be fixed by 30 October 2026.

On several pages hint text for the entire fieldset is not correctly associated with each radio. This fails WCAG 2.2 success criterion 1.3.1 Info and Relationships. This will be fixed by 30 October 2026.

On the ‘Capital Gains Tax to pay for 2026/27’ page there are visually hidden H2s with the same text as the H3s before them which does not provide a meaningful heading hierarchy. This fails WCAG 2.2 success criterion 1.3.1 Info and Relationships. This will be fixed by 30 October 2026.

Data is not always maintained when navigating backward and forward through the service. This fails WCAG 2.2 success criterion 3.3.7 Redundant Entry. This will be fixed by 30 October 2026.

Currency input boxes are aria-labelled by a ‘£’ symbol, which overrides the intended ‘label’. This fails WCAG 2.2 success criteria 2.5.3 Label in Name and 1.3.1 Info and Relationships. This will be fixed by 30 October 2026.

The first question page is missing a timeout dialog. This fails WCAG 2.2 success criterion 2.2.1 Timing Adjustable. This will be fixed by 30 October 2026.

The ‘private residence relief’ page does not have an error summary when validation is triggered. This fails WCAG 2.2 success criteria 4.1.3 Status messages. This will be fixed by 30 October 2026.

Several pages have misleading error messages. This fails WCAG 2.2 success criteria 3.3.3 Error Suggestion. This will be fixed by 30 October 2026.
