How Tax-Loss Harvesting Works
Frequently Asked Questions
How does tax-loss harvesting work for cryptocurrency?
Tax-loss harvesting for cryptocurrency involves deliberately selling assets that have declined in value to lock in capital losses before the tax year ends. Those realised losses then offset capital gains from profitable trades, reducing the amount of tax owed. For example, if you have $8,000 in gains but harvest $3,000 in losses, your net taxable gain is $5,000. After selling the losing asset, many investors immediately repurchase it to maintain their portfolio position — a strategy made possible because the wash sale rule currently does not formally apply to cryptocurrency. The net result is the same market exposure with a meaningfully lower tax bill.
Can I sell crypto at a loss and buy it back immediately for tax purposes?
Under current IRS guidance, yes — cryptocurrency is classified as property rather than a security, meaning the wash sale rule that applies to stocks and bonds does not formally extend to crypto. This allows you to sell a cryptocurrency at a loss to realise the capital loss for tax purposes and then immediately repurchase the same asset without the 30-day waiting period required for securities. However, this treatment is subject to regulatory change. Proposed legislation has sought to extend wash sale rules to cryptocurrency on multiple occasions. Relying on this strategy requires staying current with tax law developments and consulting a qualified tax professional before executing.
What happens to harvested losses if they exceed my gains?
When your total harvested losses exceed your total capital gains for the year, the excess loss is not wasted. In the United States, up to $3,000 of net capital losses can be deducted directly against ordinary income — such as salary or freelance earnings — in the current tax year, further reducing your overall tax liability. Any net losses beyond $3,000 become a capital loss carryforward, which is officially recorded and can be applied against future capital gains or income in subsequent years without any expiration. This makes aggressive tax-loss harvesting in down years particularly valuable, as large loss balances generate compounding tax benefits over multiple future years.
Common Misconceptions About Tax-Loss Harvesting
Tax-loss harvesting permanently reduces your gains — it eliminates the tax entirely.
Tax-loss harvesting defers and reduces taxes rather than eliminating them permanently. When you sell an asset at a loss and repurchase it, the new cost basis is reset to the repurchase price. If the asset later recovers and you sell at a gain, that gain will be taxable. The strategy reduces your tax bill in the current year by offsetting existing gains, but future appreciation of repurchased assets creates new taxable gains. The long-term benefit comes from the time value of deferral — paying less tax now and investing the savings, rather than avoiding taxes indefinitely.
You should always harvest every available loss, regardless of the circumstances.
Tax-loss harvesting is a tool, not a universal rule, and applying it indiscriminately can produce suboptimal outcomes. Harvesting a short-term loss to offset a long-term gain may not be efficient if the tax rates differ significantly. Transaction fees from selling and repurchasing reduce the net tax benefit. If you believe an asset is near a bottom and poised for recovery, selling and repurchasing introduces reinvestment timing risk. Harvesting should be evaluated on a case-by-case basis, weighing the tax benefit against transaction costs, potential market timing exposure, and the specific gain and loss types involved.
Tax-loss harvesting is only useful at the end of the year.
While many investors focus on tax-loss harvesting in December, the strategy can be applied at any point during the tax year when suitable opportunities arise. Cryptocurrency markets are highly volatile, and significant unrealised losses can appear and disappear rapidly. Waiting until December to review harvesting opportunities means missing losses that appeared and recovered earlier in the year. Monitoring your unrealised loss positions throughout the year — using crypto tax software or portfolio tracking tools — enables you to act on harvesting opportunities when they are most advantageous rather than being constrained to a single year-end window.
