About the Crypto Tax-Loss Harvesting Calculator

Tax-loss harvesting is a strategy where you sell cryptocurrency positions that have declined in value to realize capital losses. These losses can offset capital gains from other investments, reducing your total tax bill. If your losses exceed your gains, you can deduct up to $3,000 of net capital losses against ordinary income per year, with any remaining losses carried forward to future years.

Unlike stocks, cryptocurrency is not currently subject to the wash sale rule, meaning you can sell a crypto asset at a loss and immediately repurchase the same asset without losing the tax benefit. However, proposed legislation may change this, so stay informed about regulatory developments.

This calculator estimates your total harvestable losses from underwater positions, the tax savings from harvesting, and how much can be used against gains versus ordinary income. Use it to identify optimal times to harvest and estimate your tax benefit. This calculator is for educational purposes only and is not tax or financial advice.

When This Page Helps

Tax-loss harvesting can save hundreds or thousands of dollars in taxes each year. This calculator helps you quantify the exact tax savings before you execute trades. It also shows how harvested losses are applied โ€” first against gains, then up to $3,000 against ordinary income.

How to Use the Inputs

  1. Enter the total cost basis of your underwater crypto positions.
  2. Enter the current fair market value of those positions.
  3. Enter your total realized capital gains for the year.
  4. Enter your marginal income tax rate.
  5. Enter your capital gains tax rate.
  6. Review the harvestable loss, gains offset, and total tax savings.
Formula used
Harvestable Loss = Cost Basis โˆ’ Current FMV (for positions where FMV < Basis) Gains Offset = min(Harvestable Loss, Realized Capital Gains) Remaining Loss = Harvestable Loss โˆ’ Gains Offset Ordinary Income Offset = min(Remaining Loss, $3,000) Tax Savings = (Gains Offset ร— CG Rate) + (Ordinary Income Offset ร— Income Tax Rate) Carryforward = Remaining Loss โˆ’ Ordinary Income Offset

Example Calculation

Result: $1,920 tax savings from $15,000 harvested loss

Harvestable loss = $50,000 โˆ’ $35,000 = $15,000. It offsets $8,000 in gains: $8,000 ร— 15% = $1,200 saved. Remaining $7,000: $3,000 offsets ordinary income at 24% = $720 saved. Total savings = $1,920. $4,000 carries forward.

Tips & Best Practices

  • Crypto is currently exempt from the wash sale rule โ€” you can rebuy immediately after selling.
  • Harvest losses before year-end to offset current-year gains.
  • Even if you have no gains, harvest $3,000 in losses to offset ordinary income.
  • Track your cost basis carefully โ€” you can only harvest if your basis exceeds current FMV.
  • Consider transaction costs and potential price movement when harvesting.
  • Watch for proposed legislation that may apply wash sale rules to crypto.
  • Harvesting doesn't mean giving up the position โ€” rebuy after selling to maintain exposure.

How Tax-Loss Harvesting Works

You sell crypto positions that are below your cost basis, realizing a capital loss. This loss offsets realized gains, reducing your tax bill. Because crypto isn't subject to the wash sale rule, you can immediately repurchase the same asset.

Maximizing Tax Savings

Harvest throughout the year, not just at year-end. Market dips present opportunities to lock in losses while maintaining your long-term position. Pair harvesting with your overall portfolio rebalancing strategy.

The $3,000 Ordinary Income Deduction

If your harvested losses exceed your capital gains, you can deduct up to $3,000 against ordinary income each year. At a 24% tax rate, that's a guaranteed $720 annual tax savings. Unused losses carry forward indefinitely.
