1. Overview of Taxes and National Insurance in the UK
In the UK, including London, taxes and National Insurance contributions (NICs) are mandatory payments deducted from your income to fund public services such as healthcare (NHS), education, and pensions. These systems are managed by HM Revenue and Customs (HMRC).
- Income Tax: A tax on your earnings above a certain threshold.
- National Insurance (NI): Contributions that fund state benefits like pensions, unemployment support, and maternity leave.
Both are automatically deducted from your salary if you are employed, but if you are self-employed, you are responsible for calculating and paying them yourself.
