Understanding the Basics

What Is Self Assessment?

Self Assessment is the system HMRC uses to collect Income Tax. Tax is usually deducted automatically from wages and pensions, but people and businesses with other income (like dividends, property, or self-employment) must report it in a tax return.

Who Needs It?

Sole traders earning £1,000+, directors, landlords, and high income earners (£100k+).

Key Deadlines

Online returns must be filed and tax paid by 31st January after the tax year ends.

Late Penalties

Automatic £100 fine if one day late. Interest and further penalties accrue quickly.

Your Responsibility

You must register by 5th October in your second tax year of business.
