There is a lot of talk about unrealized capital gains, and it can be a bit confusing to understand how they affect you and your tax liabilities. Unrealized capital gains, in particular, can play a significant role in your investment strategy. These gains have the potential to impact your portfolio’s performance, tax obligations, and long-term financial goals.
This guide aims to demystify unrealized capital gains. You’ll learn what they are, why they matter, strategies to maximize their potential, and the tax implications of realizing gains. By the end of this post, you’ll have actionable insights to make more informed decisions about your investments.
What Are Unrealized Capital Gains?

Unrealized capital gains are the difference between the current value of an unsold asset and its original purchase price. These gains are often called “paper profits” because they exist only on paper until the asset is sold. Once you sell an asset that has appreciated in value, the unrealized gain becomes a realized gain. This means you have officially locked in the profit and taxes are then owed.
Unrealized gains can apply to various types of investments, including stocks, real estate, bonds, and mutual funds. Even collectibles, such as art, antiques, baseball cards, or comic books, can appreciate in value over time. These items create unrealized gains as market prices fluctuate.
An Example of Capital Gains in Real Estate
To illustrate, imagine you bought a house in 2024 for $220,000. You recently had it appraised, and its current market value is $245,000. That means your home has an unrealized gain of $25,000. However, this doesn’t mean you suddenly have an extra $25,000 to spend, nor do you have to pay taxes on the additional value.
Since the gain only exists on paper, you would need to sell the house to convert that profit into cash. Additionally, market conditions can change. If the housing market fluctuates, that $25,000 in paper profits could disappear, potentially leaving you with less than your original investment.
This example highlights an important reality. Market conditions are unpredictable, and unrealized gains are never guaranteed. The value of your investments can fluctuate due to market volatility, which is characterized by rapid price changes. If prices drop significantly, an unrealized gain can quickly turn into a loss. Because of this uncertainty, profits are only secured once an asset is sold.
When to Realize Gains vs. When to Hold Unrealized Gains

Deciding whether to sell an asset and lock in profits or hold onto it for potential future gains depends on several key factors. Selling may be the right choice when you believe the current market price is at its peak, you need cash for another purpose, or the asset carries significant risks if held longer.
Conversely, holding may be preferable when an asset still has growth potential, your investment horizon is long-term, and market conditions favor continued appreciation.
When to Realize Gains
You should consider selling an asset to realize gains if:
- Market conditions are shifting: If the market shows signs of a downturn or increased volatility, selling to lock in profits may be a prudent move.
- Your investment goals require liquidity: If you need funds for a near-term goal, such as a down payment on a house or another major expense, realizing gains might be necessary.
- Tax implications favor selling now: Consider the capital gains tax rate and whether selling at this moment aligns with your overall tax strategy.
- Better investment opportunities arise: If you identify alternative investments with stronger growth potential, selling to reallocate funds might be beneficial.
When to Hold Unrealized Gains
It may be wise to hold onto an asset if:
- You have a long-term outlook: If you believe the asset has strong potential for future growth, keeping it despite current gains could be advantageous.
- The asset’s fundamentals remain strong: A company with solid financial performance and positive industry trends may continue appreciating over time.
- Market sentiment is positive: If the broader market outlook supports continued growth for the asset class, holding might be a better strategy.
Ultimately, the decision to sell or hold depends on your financial goals and timing. A well-balanced investment approach considers both the need to secure profits and the potential for long-term wealth accumulation.
Strategies to Maximize the Potential of Unrealized Capital Gains

Effectively managing unrealized capital gains can help reduce tax liability and enhance long-term wealth growth. Below are key strategies to maximize their potential:
Hold Investments for Over a Year
Holding investments for more than a year before selling qualifies them for long-term capital gains tax rates, which range from 0% to 20%, compared to 10% to 37% for short-term gains. This is especially beneficial for high earners who would otherwise be taxed at ordinary income rates. Certain assets, such as collectibles or qualified small business stock, may still be taxed at a higher rate of 28%, so it’s essential to plan accordingly.
Beyond the tax benefits, holding investments for longer periods also allows for compounding growth over time.
Bequeath Appreciated Assets for a Step-Up in Basis
Passing down appreciated investments through inheritance can eliminate capital gains taxes for heirs.
For example, if you purchased stock for $100,000 and its value appreciated to $250,000, selling it would result in taxes on the $150,000 gain. However, if inherited, the cost basis would reset to the current $250,000 market value, minimizing tax liability for the beneficiary.
This strategy prevents the tax liability associated with capital gains from being transferred to your heirs.
Time Capital Gains Harvesting for Tax Efficiency
Strategically realizing capital gains in low-income years or spreading them across multiple years can help keep you in a lower tax bracket.
Selling higher-basis assets first minimizes taxable gains, while offloading lower-basis investments in lower-income years is ideal.
Investors near the net investment income tax (NIIT) threshold, $200,000 for single filers, or $250,000 for joint filers, should strategically plan sales to avoid the 3.8% surtax. Additionally, gradually realizing gains prevents bracket creep.
Use Tax Loss Harvesting to Offset Gains
Selling underperforming investments at a loss can offset capital gains and reduce taxable income. If you realize a $50,000 loss and a $40,000 gain, your net taxable gain is eliminated.
Additionally, up to $3,000 of net losses can reduce ordinary income each year, with excess losses carried forward for future use. This strategy ensures tax-efficient investing while maintaining a well-balanced portfolio.
Donate Appreciated Assets to Charity
Donating long-term appreciated assets directly to a qualified charitable organization allows you to avoid capital gains taxes and claim a tax deduction of up to 30% of your adjusted gross income.
This strategy is more efficient than selling the asset first and donating cash, as it maximizes both tax savings and charitable contributions. Charitable remainder trusts (CRTs) can also be used to generate income while benefiting charitable causes.
Allocate Assets to Tax-Efficient Accounts
Investing in tax-advantaged accounts such as IRAs, 401(k)s, 529 plans, and HSAs can shield gains from taxation. By strategically placing assets in the right accounts, investors can optimize after-tax returns and maintain more control over distributions.
Expand Beyond Tax Efficiency: Reinvestment, Diversification & Collateralized Loans
Maximizing unrealized capital gains isn’t just about reducing taxes. Investors can:
- Reinvest gains into higher-growth opportunities, such as private equity, real estate, or innovation-driven sectors. This helps compound returns and ensures capital remains productive. For example, if you sell a rental property for $500,000 and reinvest the proceeds into another property, you can defer paying capital gains taxes indefinitely as long as you continue reinvesting through a 1031 exchange.
- Diversify portfolios by reallocating gains into different asset classes to manage risk while enhancing returns. Avoiding over-concentration in one asset class ensures stability, particularly in volatile markets.
- Leverage gains through collateralized loans, using appreciated assets as collateral for low-interest loans instead of selling and triggering capital gains taxes. Borrowing against assets preserves market exposure and allows for liquidity without incurring immediate tax consequences.
The Tax Implications of Realizing Gains

Unrealized gains are not considered taxable income because they remain theoretical until the asset is sold. However, their value is not guaranteed. If the market declines, these paper gains could disappear before they are ever realized. Although unrealized gains are not taxed, they become subject to capital gains tax once an asset is sold.
While unrealized gains do not immediately affect your tax bill, they still play a crucial role in financial planning. They provide insight into your net worth and portfolio performance, helping you decide whether to hold or sell an investment. Additionally, unrealized gains can impact borrowing, as some investors use the increased value of their stocks or property as collateral for loans before selling the asset.
To navigate the tax implications of realizing gains effectively, it is important to consider the following key factors:
- Short-Term vs. Long-Term Capital Gains: Assets held for less than a year are taxed at ordinary income rates, while long-term holdings benefit from lower capital gains tax rates.
- State Taxes: Some states impose additional capital gains taxes, which should be factored into investment decisions.
- Net Investment Income Tax (NIIT): High-income investors may be subject to an additional 3.8% tax on investment income.
- Step-Up in Basis: If assets are inherited, their cost basis may reset to the current market value, potentially eliminating unrealized gains for heirs.
Next Steps for Investors
Managing unrealized capital gains can be a powerful tool in your investment arsenal. The key is to stay informed, make decisions based on your financial goals, and leverage tax-efficient strategies.
If you’re ready to take control of your investment strategy, start by reviewing your portfolio. How many of your assets are unrealized gains? Could you optimize your returns by holding longer, diversifying, or using strategies like tax-loss harvesting?
Smart investing isn’t just about growth, it’s also about optimizing every aspect of your financial decisions. The more you understand about unrealized capital gains, the better positioned you’ll be to make strategic moves that align with your long-term goals.
