What Is an Active vs Non-Trading Company for Corporation Tax?

  • Modified: 13 May 2026

HMRC classifies companies as active (trading) or non-trading (dormant) for Corporation Tax purposes.

An Active Company is liable for Corporation Tax if it:

  • Carries out business activities or professional services.
  • Buys or sells goods and assets to make a profit.
  • Provides core services or earns interest on assets.
  • Manages investments or receives income from other sources.

A Non-Trading Company is considered dormant if it:

- Has not yet started trading, or
- Has ceased trading and had no activity during the whole year

Dormant companies are generally not required to file a Corporation Tax return once HMRC has been formally notified of their dormant status.

<b>Important:<i> If HMRC does not consider your company dormant, you must notify them or risk penalties.
