Thanks for the feedback. My situation is very simple with no real estate or other complications. The only capital gains I might incur in the future would be selling ETFs in my taxable account, the same ETFs I am considering tax loss harvesting for.
If we continue with Heckler's example, summarized as: VCN with an ACB of $38 was sold for $37, harvesting a capital loss of $1/share. VDY is then purchased at $37/share, grows to $45 and when sold the capital gain of $8 can be reduced by the capital loss of $1, thus incurring taxes on only $7.
To me it looks there is no net gain from this transition. Had he never sold the $38 VCN in the first place, a growth to $45 and subsequent sale would have still incurred taxes on $7 of capital gains. The exact same end result.
So I think in my situation there is no benefit in tax loss harvesting, now or in the future. Agree?
