Some areas of the site require you to actively submit information in order for you to benefit from specific features (such as the range of online services). You will be informed at each information collection point what information is required and what information is optional.
Some of this information may be personal (information that can be uniquely identified with you, such as your full name, address, email address, phone number etc).
HMRC only collect such information when you choose to supply it to them.
Information is also gathered without you actively providing it, through the use of various technologies and methods such as Internet Protocol (IP) addresses and cookies. These methods do not collect or store personal information.
An IP address is a number assigned to your computer by your Internet Service Provider (ISP), so you can access the internet. It is generally considered to be non-personally identifiable information, because in most cases an IP address is dynamic (changing each time you connect to the internet), rather than static (unique to a particular user's computer).
HMRC use your IP address to diagnose problems with their server, report aggregate information, and determine the fastest route for your computer to use in connecting to the site, and to administer and improve the site.
HMRC uses small bits of data stored on your computer called 'cookies'. Find out what HMRC uses them for, and how to control their use.
Sometimes HMRC tag pages on sites used to promote various campaigns. These tags are provided by the advertising management partner, DoubleClick. These tags enable DoubleClick to recognise a unique cookie on your browser, which in turn enables HMRC to learn which advertisements bring users to the website. The cookie was placed by HMRC, or by another advertiser who works with DoubleClick. With this technology, the information that HMRC collect and share is anonymous and not personally identifiable. It does not contain your name, address, telephone number, or email address. There is more information about DoubleClick - including information about how to opt out of these technologies - on their website.
HMRC may monitor email communications with HMRC (this includes any HMRC member of staff). Any such monitoring will take place in accordance with the law.
HMRC use log files generated by the web servers to analyse site usage and statistics but the files do not identify any personal information. Log file analysis helps HMRC to understand usage patterns on the website and to make improvements to the service.
HMRC do not disclose any information you provide via the site to any third parties or other Government departments except where:
HMRC will take all reasonable steps in accordance with legal obligations to update or correct, personally identifiable information that you submit via this site.
You have a right to ask to see details of any personal information that HMRC hold about you. If you wish to do so please contact the HMRC office that you have been dealing with.
HMRC has a legal duty to protect the confidentiality of taxpayer information. HMRC take all reasonable steps to protect any information you submit via the website, both online and offline, in accordance with legislation such as the Data Protection Act 1998.
HMRC take all appropriate steps to protect your personally identifiable information as you transmit your information from your computer to the HMRC site and to protect such information for loss, misuse, and unauthorised access, disclosure, alteration, or destruction. HMRC use leading technologies and encryption software to safeguard your data, and operate strict security standards to prevent any unauthorised access to it.
Where you use passwords, ID numbers, or other special access features on this site, you also have a responsibility to take reasonable steps to safeguard them.
