A tax on your earnings and other income, deducted through PAYE or paid via Self Assessment.
Income Tax is the main tax on your earnings in the UK. You have a Personal Allowance (the amount you can earn before tax is due), then pay tax at the basic, higher, or additional rate depending on your income band. Most employees pay Income Tax automatically through PAYE, while self-employed individuals pay via Self Assessment.
