I’m still exploring paths forward, agree going back to employment and transferring into a new restrictive Pillar 2 blunts the advantage here. Most likely rain I don’t follow through with it. The option where I see this winning is using a VB account to invest, which means not doing that! Instead leaving the country, self-employment, early retirement, or the questionable approach in (Temporary) vested benefits account strategy.
With the additional contribution my Pillar 2 would still be less than 30% of my portfolio. VB would be a great place to invest in fixed income and also diversify into dividend shares (which depends on the VB provider having an Income Stocks Fund on the menu). In that case the tax benefit would be substantial ongoing.
