Any dentist thinking of retiring needs to plan for the event, and that planning should include how to maximise Capital Gains Tax retirement relief. With assets having to be held for 10 years prior to retirement, that planning should start when the dentist reaches 45 years of age. As every dentist's circumstances are different, it is a tax that can become complicated. The best advice is to review your tax planning with your dental accountant as early as possible, and ensure you make the most of your practice assets.
