Tax-Smart

Tax parameters
Blended LT cap gains + NIIT. Gains inside IRAs and the trust are not taxed currently.
Embedded gain fraction. A trim of $X in taxable realizes this % × $X of gain.
On Path B, realized gain in the taxable account is offset dollar-for-dollar by this amount before tax is applied.

Sum of all over-band positions
Assumption (Path B capacity): Each account is assumed to hold the household-level allocation. Equity held in tax advantaged accounts = (His IRA + Her IRA + Family Trust) × current equity fraction. This simplification is conservative: if the tax advantaged accounts hold more equities than average, capacity is higher and tax savings increase.

Re-derive: drift dollar = (current% - target%) x household value. Tax saved = Path A tax minus Path B tax.
