Year-End Reminder: Review Your Taxable Gains/Losses in Black Diamond
December 5, 2025

As we approach year-end, this is a good time to review your realized gains and losses.
Please log into your Black Diamond client portal and do the following:
- Go to Portfolio Dashboard
- Click on the Gains/Losses tab
- Review your realized gains and any realized losses for any taxable accounts for 2025
If you expect to owe taxes this year, or if you want to see whether we can reduce your taxable gains, reply to this email and we will take a look.
A few quick notes:
• If you are invested solely in our Equity Innovation portfolio, almost all positions are up this year, so there is typically very little we can harvest for tax savings.
• If you have exposure to Equity Growth, Equity Core, or Equity Low Volatility, there are positions in those strategies that are down this the year. Depending on your specific holdings, we may be able to lower your taxable income by harvesting losses.
• Every client’s portfolio is different, so this is handled case by case.
How to Access the Right Numbers Inside Black Diamond
Start on the Portfolio Dashboard page.
Top-left filter:
Select only your taxable accounts (Individual or Joint).
Exclude retirement accounts since they don’t create taxable gains.
Top-right filter:
Set the date range to Year-to-Date.
This ensures you are viewing realized gains for 2025 only.

After those two filters are applied, scroll to the Gain/Loss section.
You’ll see two groups of numbers:
- Unrealized (not relevant for taxes)
- Realized (this is what matters)

In the realized section, you’ll see:
- Short-Term Realized Gain/Loss
- Long-Term Realized Gain/Loss
These are the numbers used to estimate your taxes.
How to Estimate Taxes From the Realized Section
Short-Term Realized Gains
These are taxed at your ordinary income rate.
Example:
If short-term realized gains are $40,494 and your bracket is 24%, the estimate is:
$40,494 × 24% = $9,719
That’s your estimated short-term tax.
Long-Term Realized Gains
Taxed at 15% or 20% depending on income.
Single filers:
• 15% up to $518,900 taxable income
• 20% above that
Married filing jointly:
• 15% up to $583,750 taxable income
• 20% above that
Example:
If long-term realized gains are $102,760 and you fall into the 15% bracket:
$102,760 × 15% = $15,414
That’s your estimated long-term tax.
Total Estimated Tax
Add the two amounts together: Total Tax Owed = ($9,719 + $15,414) = $25,133
Specific Scenarios
Sometimes the numbers won’t line up perfectly — for example:
- Positive short-term but negative long-term
- Positive long-term but zero or negative short-term
- Realized losses but a positive total gain
- Any mix that doesn’t look straightforward
