Capital Gains Tax
Definition
Tax applied to the profit from selling an asset at a higher price than its purchase cost.
Why it matters
It affects the net return from any realized gain. The rate and timing rules vary significantly by jurisdiction.
What most investors miss
The gap between what the term means and how it is usually applied.
They optimize for pre-tax return without modeling the after-tax result. The best gross return is not always the best net return.
How to read it
Model tax on realized gains before deciding to sell. Holding period and jurisdiction both change the tax rate.
Multi-account lens
How this term reads differently across brokers and accounts.
Realized gains across multiple accounts may be aggregated for tax purposes or treated separately depending on jurisdiction. The order of sales across accounts can also affect the total tax bill.
