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.
