Who Needs to File a Self Assessment Tax Return?

HMRC requires individuals with non-PAYE income, directors, landlords, and high earners to register and submit an annual SA100 return.

Sole Traders & Freelancers

If you earned more than £1,000 from self-employment during the tax year, you must register for Self Assessment and report your business profits and expenses.

Company Directors

Limited company directors who receive dividend payments, director's loan income, or untaxed income must file a personal tax return to declare dividend tax liabilities.

Property Landlords

Landlords receiving rental income from UK or overseas property must declare rental profits, claim Section 24 mortgage interest relief, and account for tax accurately.
