A personal tax account is an online account that is provided by HM Revenue and Customs (HMRC) in the United Kingdom. It allows individuals to view and manage their tax affairs online, including viewing their tax code, checking their tax credits, and making payments towards their tax liability.

To set up a personal tax account, an individual will need to provide their National Insurance number and some personal details. They will also need to create a username and password to access the account.

Once an individual has set up their personal tax account, they can use it to view their tax information and update their personal details (such as their address or contact information). They can also use the account to make payments towards their tax liability, claim tax refunds, and submit their tax return online.

A personal tax account is a convenient way for individuals to manage their tax affairs and stay on top of their tax obligations. If you have any questions about setting up or using a personal tax account, you can contact HMRC for assistance.
