You are required to complete a "self assessment" tax return every year, providing full details of your income and capital gains. These figures will determine the amount of tax you will be required to pay (subject to any further checks).
The tax year runs from April 6th until April 5th of the next year.
Deadline for paper tax returns — 31 October.
Deadline for online tax returns — 31 January.
