I earned £85,000 this year and made £15,000 from selling shares. What’s my total tax liability?
Based on the 2024/25 tax year: Your Income Tax is £18,432, NICs are £4,964.16, and CGT on shares (after £3,000 allowance) is £2,400. Total estimated liability: £25,796.16
How can I reduce my CGT?
Consider: ISA sheltering (£20k/yr tax-free), bed & ISA strategies, pension contributions to reduce income band, and harvesting losses. Shall I model these scenarios?
