Crypto Loss Harvesting Calculator
Identify crypto positions with unrealized losses for tax-loss harvesting opportunities. Enter values for instant results with step-by-step formulas.
Formula
Tax Savings = (Loss Offsetting Gains x Cap Gains Rate) + (min(Remaining Loss, $3,000) x Income Tax Rate)
Realized crypto losses first offset capital gains at the applicable capital gains rate. Remaining net losses offset up to $3,000 of ordinary income per year. Any excess carries forward indefinitely to future tax years.
Worked Examples
Example 1: Harvesting Losses to Offset Gains
Problem: You bought crypto for $50,000 (now worth $30,000) and have $15,000 in realized gains this year. You are in the 24% bracket with 5% state tax. Calculate tax savings from harvesting the $20,000 loss.
Solution: Unrealized loss = $50,000 - $30,000 = $20,000\nOffset against gains: min($20,000, $15,000) = $15,000\nRemaining loss: $20,000 - $15,000 = $5,000\nOrdinary income offset: min($5,000, $3,000) = $3,000\nCarry forward: $5,000 - $3,000 = $2,000\n\nTax savings from gain offset = $15,000 x (24% + 5%) = $4,350\nTax savings from income offset = $3,000 x (24% + 5%) = $870\nTotal current-year savings = $4,350 + $870 = $5,220
Result: Tax Savings: $5,220 | Carry Forward: $2,000 | Effective Savings Rate: 26.1%
Example 2: Large Loss Carry-Forward Scenario
Problem: You have $80,000 in unrealized crypto losses and only $5,000 in gains. At a 32% bracket, how much saves this year and how long to use the remaining loss?
Solution: Offset gains: $5,000\nRemaining loss: $80,000 - $5,000 = $75,000\nOrdinary income offset (year 1): $3,000\nCarry forward: $75,000 - $3,000 = $72,000\nYears to carry forward: $72,000 / $3,000 = 24 years\n\nYear 1 tax savings:\nGain offset = $5,000 x 0.32 = $1,600\nIncome offset = $3,000 x 0.32 = $960\nYear 1 total = $2,560\nTotal future savings = $72,000 x 0.32 = $23,040 (over 24 years)
Result: Year 1 Savings: $2,560 | Carry Forward: $72,000 | Full Recovery: ~24 years
Frequently Asked Questions
How much can crypto losses offset against ordinary income?
Under current US tax law, net capital losses (after offsetting all capital gains) can offset up to $3,000 per year of ordinary income ($1,500 if married filing separately). Any losses exceeding the $3,000 limit carry forward to future tax years indefinitely. For example, if you have $25,000 in crypto losses and only $10,000 in gains, you have $15,000 in net losses. In the current year, $3,000 offsets ordinary income, and $12,000 carries forward. Over the next 4 years, you can offset $3,000 per year, with no expiration on the remaining balance. The $3,000 annual limit applies to the total of all net capital losses across all asset classes, not just crypto. This means crypto losses also offset stock gains and vice versa.
When is the best time to harvest crypto losses?
The optimal timing for crypto tax-loss harvesting depends on several factors including market conditions, your overall tax situation, and your investment outlook. Many investors harvest losses in December to maximize deductions for the current tax year before the December 31 deadline. However, harvesting throughout the year can be more effective because you capture losses during market dips that may recover before year-end. Significant market downturns (30%+ drops) present excellent harvesting opportunities because unrealized losses are largest. Consider harvesting when you have substantial realized gains from other sales that need offsetting, when your tax bracket is unusually high for the year, or when you want to rebalance your portfolio anyway. Avoid harvesting losses just to save on taxes if it conflicts with your long-term investment strategy.
Can I harvest losses on multiple crypto positions simultaneously?
Yes, you can harvest losses across multiple crypto positions at the same time. In fact, reviewing your entire crypto portfolio for loss harvesting opportunities is recommended rather than focusing on a single position. Different positions may have different cost bases, holding periods, and unrealized loss amounts. A systematic approach involves listing all positions with unrealized losses, calculating the tax savings from each, and prioritizing positions where the loss is largest relative to the remaining position value. Be aware that harvesting losses on many positions simultaneously can trigger significant trading fees on some platforms. Also consider whether you want to repurchase these assets after selling, as maintaining your desired portfolio allocation requires reinvestment. Some investors use similar but not identical assets as substitutes while waiting.
What are the risks and downsides of crypto tax-loss harvesting?
While tax-loss harvesting is generally beneficial, several risks should be considered. First, selling at a loss means you exit a position that might recover, potentially missing significant gains if the market rebounds quickly. Second, if wash sale rules are extended to crypto retroactively, previously harvested losses could be disallowed. Third, frequent trading to harvest losses generates transaction fees and may trigger additional taxable events if you are not careful. Fourth, resetting your cost basis to a lower amount means future sales will generate larger taxable gains, effectively deferring taxes rather than eliminating them. Fifth, the $3,000 ordinary income deduction limit means large losses take many years to fully utilize against income. Finally, managing the tax records for multiple harvest transactions adds complexity to your tax filing.
How does crypto loss harvesting affect my cost basis?
When you sell crypto to harvest a loss and then repurchase the same asset, your cost basis resets to the new purchase price. This has important long-term implications. For example, if you bought Bitcoin at $50,000 and sold at $30,000 to harvest a $20,000 loss, then repurchased at $30,000, your new cost basis is $30,000. If Bitcoin later rises to $50,000 and you sell, you owe capital gains tax on $20,000 of gain. Without harvesting, selling at $50,000 would have resulted in zero gain. This means tax-loss harvesting does not eliminate taxes but rather defers them to the future while providing immediate tax savings. The time value of money makes this generally advantageous because tax dollars saved today are worth more than tax dollars paid in the future.
Can I use crypto losses to offset stock market gains?
Yes, capital losses from cryptocurrency can offset capital gains from stocks, bonds, real estate, and any other capital asset. The IRS treats all capital gains and losses together regardless of the asset type. This cross-asset offset capability makes crypto loss harvesting particularly valuable during years when you have significant stock market gains. For example, if you have $30,000 in stock gains and $20,000 in crypto losses, harvesting the crypto losses reduces your taxable capital gains to $10,000. This saves you $3,000 to $5,000 in taxes depending on your rate. Similarly, stock losses can offset crypto gains. This comprehensive approach to tax planning across all asset classes maximizes the benefit of loss harvesting and is why reviewing your entire investment portfolio holistically during tax planning season is essential.
