Tax Wrapper Review: Am I Using ISA, SIPP and GIA Optimally?

Holding the same fund in an ISA versus a taxable account can quietly cost you for years. You list your ISA, SIPP and GIA holdings plus your tax rate and remaining allowances; this reviews whether each asset sits in the most tax-efficient wrapper, where you are wasting allowance, and what should move where. For investors with money spread across accounts who suspect it is not arranged well.

Review my use of tax-efficient wrappers and tell me whether I am holding the right assets in the right places. My current setup is: ISA holdings: {ISA_HOLDINGS}; SIPP holdings: {SIPP_HOLDINGS}; General Investment Account holdings: {GIA_HOLDINGS}. My marginal income tax rate is {INCOME_TAX_RATE}%, my annual ISA allowance used is {ISA_ALLOWANCE_USED}, and my SIPP annual allowance remaining is {SIPP_ALLOWANCE_REMAINING}. Explain: (1) the asset location principle and why it matters; (2) which of my current holdings are sub-optimally placed and why; (3) a prioritised action plan to relocate assets across wrappers for maximum tax efficiency. Account for capital gains tax implications of moving GIA positions.
