Tax-Loss Harvesting with Crypto Assets

As digital assets are added to investment portfolios, traditional strategies are evolving as well. One such approach is tax-loss harvesting—the practice of selling losing investments to offset taxable gains. As crypto portfolios grow more complex, tax-loss harvesting is now a key strategy.

This blog will explain crypto tax-loss harvesting. You’ll learn what it is, why it matters, and how it works in 2025. Also, find out how to boost your after-tax returns with it. No matter if you hold crypto casually or trade actively, knowing how to offset gains can be a useful tool for your finances.

Why It Matters

The Tax Reality of Crypto Gains

In most jurisdictions, including the U.S., the U.K., and Australia, cryptocurrency is treated as property for tax purposes. This means every sale, swap, or conversion could trigger a taxable event, where you owe tax on capital gains. Given how volatile crypto markets can be, gains can accumulate quickly, especially during bull runs.

The same volatility can cause sharp downturns. This creates chances to sell underperforming assets at a loss. You can then use those losses to lower your taxable income. Without a proper tax-loss harvesting strategy in place, investors could end up paying more in taxes than necessary.

Rising Scrutiny and Regulation

In 2025, global tax authorities have tightened reporting rules for digital assets. As governments develop new frameworks for crypto, transparent and efficient tax planning isn’t just smart—it’s essential. Tax-loss harvesting helps investors cut liabilities while staying true to their investment goals.

Key Benefits

1. Offset Capital Gains

The primary benefit of tax-loss harvesting is the ability to offset realised gains with realised losses. If you made $10,000 by selling Ethereum but lost $4,000 on an altcoin, you can use that loss. This lowers your taxable gain to $6,000.

2. Reduce Ordinary Income (Where Applicable)

In some countries like the U.S., you can apply up to $3,000 of net capital losses to reduce your ordinary income (e.g., from a job or business). This can be especially useful in years where your investment performance was negative overall.

3. Carry Losses Forward

If your losses are greater than your gains and the ordinary income deduction limit, you can usually carry the excess forward. This will help offset future capital gains. This feature helps smooth out your tax obligations over time and can support a longer-term portfolio strategy.

4. Rebalance Without Penalty

Tax-loss harvesting is a great way to rebalance your portfolio. Plus, it helps you avoid unnecessary taxes. Selling underperforming assets lets you take the loss. It also frees up funds to invest in better-performing or more strategic options.

Additional Expert Tips & Common Mistakes to Avoid

Expert Tips

Plan Year-Round, Not Just at Tax Time

Many investors only start thinking about taxes in Q4 or early the following year. Tax-loss harvesting should be a regular practice. This is key in the crypto market, where prices can change quickly.

Use Crypto Tax Tools

Platforms such as Koinly, CoinTracker, and TokenTax automate loss calculations. They also flag opportunities all year. These tools work with wallets and exchanges. They provide real-time insights into unrealized losses.

Consider Transaction Costs

While harvesting a loss can be tax-efficient, always consider network fees and trading commissions. On-chain trades, particularly on Ethereum, can be expensive. Weigh those costs against the potential tax savings before proceeding.

Common Mistakes

Ignoring the Wash Sale Rule Nuances

The wash sale rule stops investors from claiming a loss on stocks. This happens if they buy the same or a very similar asset again within 30 days. The IRS hasn’t enforced this rule for crypto by 2025, but that may change. Some other places already have similar rules in place. To be safe, avoid rebuying the same asset immediately after selling it for a loss.

Harvesting When You Should Be Holding

Don’t let taxes alone drive your investment decisions. Selling assets just to create a loss can be counterproductive if it moves you away from your long-term goals. Always balance tax benefits with your broader portfolio strategy.

Not Keeping Accurate Records

Every trade, transfer, or swap can affect your cost basis. If you don’t track detailed records, you might underreport income, misreport losses, or face issues during audits. Use software or a spreadsheet that logs time, price, amount, and wallet/exchange details for each transaction.

Advanced Insights and Expert Recommendations

Identifying the Best Assets for Harvesting

To identify the best candidates for tax-loss harvesting, consider the following criteria:

• High unrealised losses
• Low likelihood of near-term recovery
• Redundancy in your portfolio
• Poor fundamentals

These may include altcoins that have fallen sharply in value or tokens tied to projects no longer actively developed.

Pairing with Tax-Gain Harvesting

Advanced investors sometimes combine tax-loss harvesting with tax-gain harvesting. For example, you can sell a winning position in a low-tax year while also selling a losing position to offset the gain. This kind of bracket management can help reduce taxes across multiple years.

International Considerations

Tax laws vary significantly by country. For instance:

• In the U.K., the “bed and breakfasting” rule requires a 30-day wait before repurchasing the same asset.
• In Canada, superficial loss rules are similar and disallow repurchasing within 30 days.
• In the U.S., current law doesn’t apply wash sale rules to crypto, but legislation is pending.

If you’re a global investor, it’s best to consult a crypto-savvy tax advisor who understands cross-border implications.

Using Losses to Your Strategic Advantage

Harvested losses can also be used to lower tax obligations on non-crypto gains, such as stock sales or real estate. If you think you’ll be in a higher tax bracket later, keeping carryforward losses can lower your tax burden when your income goes up.

When used thoughtfully, it can help you:

• Offset short- and long-term capital gains
• Lower your annual tax bill
• Reposition your portfolio without additional tax burdens
• Carry forward losses to minimise future liabilities

Smart Tax Planning for Better Returns

Tax-loss harvesting with crypto assets is more than a tax trick—it’s a strategic approach to portfolio management.

As regulations continue to evolve in 2025, staying informed and proactive is key. Using the right tools, timing, and expert advice can boost your tax results. This way, your crypto strategy will work as hard as you do.

Don’t wait until year-end to think about taxes. Begin tracking your portfolio now. Look for harvesting opportunities as they come up. Also, keep detailed records. Tax efficiency is a year-round game—and one that smart investors always play to win.
