What Are Unrealized Gains and Losses?

Key takeaways

• The "Paper" Status: Gains and losses are not permanent; they fluctuate with the market until the asset is disposed of.

• 2026 Reporting Shift: New reporting frameworks (CARF, 1099-DA) mean tax authorities now have visibility into your unrealized holdings, even if they aren't taxed yet.

• The 1099-DA Trap: Most brokers report "Gross Proceeds" but often lack your original "Cost Basis," leading to potentially inflated tax bills.

• Strategic Utility: Unrealized losses can be strategically harvested to offset realized gains, reducing your overall tax liability.

• Blockstats Integration: High-compliance tools are now required to bridge basis gaps across multiple platforms.

Unrealized gains and losses represent the change in the market value of an asset you still own compared to its original purchase price, often referred to as "paper" profits or losses.

Because the asset is still in your possession, the value is subject to market volatility. Today’s massive unrealized gain could become tomorrow’s unrealized loss if the market shifts. In the financial world, these are "open positions" that only become final once a transaction occurs.

What are unrealized gains?

An unrealized gain is the increase in an asset's market value above its original cost basis before the asset has been sold or traded for another currency. 

It is important to remember that an unrealized gain does not put cash in your hand. You cannot spend an unrealized gain at the grocery store without first selling the asset. However, in the 2026 tax season, these gains affect your ability to secure loans or your standing in jurisdictions with high-net-worth reporting requirements.

Example of unrealized gains

Imagine you purchased 1 Bitcoin (BTC) in early 2025 when the price was $40,000. By mid-2026, the price of Bitcoin has surged to $95,000.

• Current Value: $95,000

• Cost Basis: $40,000

• Unrealized Gain: $55,000 You are up by $55,000 on paper. If the price drops to $70,000 tomorrow, your unrealized gain shrinks. It only becomes a "realized" gain if you sell at the $95,000 mark.

What are unrealized losses?

An unrealized loss is a decrease in the market value of an asset below its purchase price while the investor still retains ownership of that asset.

An unrealized loss is often described as being underwater. While it feels like a loss of wealth, the loss isn't final until you sell. If the asset's price eventually recovers and surpasses your cost basis, that unrealized loss can transform back into an unrealized gain.

Example of Unrealized Losses

Suppose you purchased $10,000 worth of a DeFi governance token. Due to a market correction in 2026, the total value has dropped to $3,000.

• Original Investment: $10,000

• Current Value: $3,000

• Unrealized Loss: $7,000.

If you continue to hold, you haven't "lost" the $7,000 yet. However, if you sell now, you "realize" that loss, which can then be used to offset other capital gains.

Why do unrealized gains matter in 2026?

In 2026, unrealized gains matter because global tax authorities now use automated reporting (CARF and DAC8) to track your total net worth and "holding" balances in real-time.

1. Automated Reporting: Exchanges are now required to report not just your sales, but your holdings. Tax authorities now know exactly how much unrealized wealth you have.

2. The 1099-DA Basis Gap: Brokers often report that you sold $100,000 of crypto but mark your cost basis as $0 because they don't see your original purchase on a different wallet.

3. The "Wealth Tax" Momentum: With high national deficits, several jurisdictions are proposing taxes specifically on the net worth of high-wealth individuals, inclusive of their unrealized gains.

What is unrealized gains tax?

Unrealized gains tax is a proposed or specific levy on the increase in value of an investment that has not yet been sold or exchanged.

While this has historically been rare for retail investors, it is a common feature in: 

• Exit Taxes: When you move residency, some countries tax your unrealized gains as if you had sold everything the day you left.

• Wealth Taxes: Aimed at the ultra-wealthy to prevent them from holding appreciating assets for decades without ever contributing to tax revenue.

What is the difference between realized gains and unrealized gains?

A realized gain is a confirmed profit from a completed sale, whereas an unrealized gain is a theoretical "on-paper" profit from an asset you still hold.

Here's the simple comparison between realized vs. unrealized gains

Are unrealized gains taxable in 2026?

In 2026, unrealized gains remain non-taxable for most retail investors, but they are now subject to mandatory reporting via the CARF framework and the new IRS Form 1099-DA. While the IRS still operates on a realization basis, meaning you are only taxed when you sell, swap, or spend an asset.

• In the United States: Under the Infrastructure Investment and Jobs Act, brokers are now issuing Form 1099-DA. This means the IRS knows you have paper profits even if you haven't sold them yet.

• In India: Under Section 115BBH, tax is only triggered upon the transfer of a Virtual Digital Asset (VDA). Holding your crypto, despite massive price appreciation, does not trigger the 30% tax.

• The Global Shift: The OECD’s Crypto-Asset Reporting Framework (CARF) ensures that over 48 countries now automatically share data on your holding balances to prevent tax evasion.

How to manage unrealized gains in a high-compliance time

Managing unrealized gains in 2026 requires precise cost-basis tracking to reconcile the "Basis Gaps" typically found in automated broker reports like the IRS Form 1099-DA.

1. Reconcile the 1099-DA Basis Gap

The biggest risk in 2026 is the "Unknown Basis" problem. If you transfer BTC from a cold wallet to an exchange and sell it, the exchange will report the "Gross Proceeds" to the IRS but may list your cost basis as $0. Without a tool like Blockstats, you could be taxed on the full sale amount rather than just the profit.

2. Strategic Tax-Loss Harvesting

By identifying your unrealized losses before the end of the fiscal year, you can sell those assets to realize the loss and offset your realized gains, significantly lowering your tax bill.

3. Leverage Blockstats for Real-Time Oversight

Blockstats acts as your Portfolio Compliance Engine by:

• Automated Syncing: Pulling live data to show your unrealized gains across all platforms.

• Basis Reconciliation: Automatically matching transfers between wallets to ensure your cost basis is never marked as $0.

• Audit-Ready Reports: Generating the necessary documentation to prove your actual gains to the IRS or CBDT.

Conclusion

Unrealized gains and losses are the heartbeat of your 2026 investment strategy, dictating your future tax liabilities and your ability to optimize your total wealth.

As global tax authorities close the gap on crypto anonymity, the distinction between "on paper" and "realized" is becoming more transparent. The most successful investors in 2026 won't be those who just pick the right coins, but those who manage their "unrealized" portfolios with precision.

Don't let the IRS assume a unrealized gains as profit and tax you for that. 

Use Blockstats today to gain total clarity over your realized and unrealized wealth.

Frequently asked questions

Does Blockstats differentiate between realized and unrealized gains?

Yes. Blockstats features a 2026 dashboard that splits your portfolio into "Locked-in Profits" (Realized) and "Active Growth" (Unrealized), ensuring you never miscalculate your tax liability.

Do you count unrealized gains as income?

No, in 2026, unrealized gains are considered an increase in net worth. They only become taxable income or capital gains once a realization event (sale or swap) occurs.

Do you report unrealized gains to the IRS?

You do not officially report unrealized gains on your tax return. However, brokers now report your holdings to the IRS via Form 1099-DA, making independent tracking essential for audit defense.

Is unrealized gain good?

Yes, it indicates your investments are appreciating. However, it is only a "paper profit" until you sell, meaning the value can still be lost if the market crashes before you realize the gain.

Can you benefit from unrealized capital gains?

Yes. You can use unrealized gains as collateral for crypto-backed loans to access liquidity without triggering a taxable event, or hold for over a year to qualify for lower Long-Term Capital Gains rates.
