CGT Saving Tips
- Use your allowance: £3,000 per person, per year — spouses can each use it.
- ISAs & pensions: gains inside these wrappers are CGT-free.
- Offset losses: capital losses reduce gains in the same or future years.
- Time disposals: spreading gains across tax years can stay under the allowance.
