Enable Tax Optimization tells the plan to try pension income splitting and keep the version that produces the larger estate. New scenarios start with it off. It is not limited to Core or Pro.
Turn it on
Open Financial Insights and confirm Current Scenario.
At the top right, open Dashboard Settings.
Open Function Settings.
Turn on Enable Tax Optimization.
The same switch appears on the Goals header in the classic Goals view, when that view is shown. It is not on Assumptions or Planning Inputs.
What it splits
It needs a couple, with both people alive. It decides eligibility itself. It can split:
Bridge benefit
Defined-benefit pension
RIF income, from age 65
LIF income, from age 65
The on-screen description says the plan has automatically applied certain strategies to minimize income tax (e.g., pension income splitting).
CPP sharing is separate. Tax Optimization does not turn it on. Use the toggle CPP/QPP Pension Income Sharing when both people are 60 or older and both are collecting.
With the switch off, splitting comes only from toggles you add: DB Pension Income Splitting, RIF Pension Income Splitting, LIF Pension Income Splitting, and CPP/QPP Pension Income Sharing.
Where to read the result
Analysis → Plan Review → Tax Optimization Overall Summary, only while the switch is on.
In the classic Insights menu, Optimization Summary. It is greyed out while the switch is off.
Cash-flow details show the split additions and deductions for the pension, bridge, RIF, and LIF.
Whether to turn it on, and whether the split fits the client, stays with the advisor.
