How does crypto tax loss harvesting work?

You sell crypto that has dropped below your purchase price to realize a capital loss. That loss can offset capital gains and up to $3,000 of ordinary income per year, with excess losses carried forward.

What is the wash sale rule for crypto?

Current IRS wash-sale rules apply to securities, not property like crypto. However, legislation has been proposed to extend wash-sale treatment to crypto. Avoid repurchasing the same asset 30 days before or after the sale to stay safe.

How much can I save with tax loss harvesting?

Savings depend on the size of your realized losses, your marginal tax rate, and whether you have gains to offset. Use this calculator to estimate harvestable losses and tax savings for your portfolio.

How this works

Unrealized loss: (cost basis − current price) × units. Only negative values can be harvested.
Harvested loss: sum of unrealized losses, optionally reduced by the wash-sale buffer.
Tax savings: losses first offset taxable capital gains, then up to $3,000 of ordinary income, at your entered rates.
Net portfolio: current portfolio value minus the estimated tax savings you realize this year.

Important notes

• IRS rules let you deduct up to $3,000 of net capital losses against ordinary income annually.
• Excess losses carry forward indefinitely to future tax years.
• If you rebuy the same or substantially identical crypto within 30 days before or after the sale, the loss may be deferred under wash-sale rules (currently proposed for crypto; track manually).
• This is an estimate, not tax advice. Consult a CPA for your situation.
