Nobody likes losing money on investments. But if you do have positions that are in the red, there is a silver lining: tax-loss harvesting. This strategy lets you use your investment losses to reduce your tax obligations.
How Tax-Loss Harvesting Works
- You sell a crypto asset that is currently below your purchase price (crystallizing the loss)
- You use that loss to offset capital gains from other investments
- If your losses exceed your gains, you may be able to offset ordinary income or carry losses forward
- You can rebuy the same asset after selling (crypto may not be subject to wash sale rules in many jurisdictions, but check your local laws)
Simple Example
| Asset | Bought For | Current Value | Gain/Loss |
|---|---|---|---|
| Bitcoin | $30,000 | $50,000 | +$20,000 gain |
| Ethereum | $3,000 | $1,500 | -$1,500 loss |
| Altcoin X | $1,000 | $200 | -$800 loss |
If you sell all three:
- Total gains: $20,000
- Total losses: $2,300
- Net taxable gain: $17,700 (instead of $20,000)
You saved taxes on $2,300 worth of gains by harvesting the losses.
Strategic Tax-Loss Harvesting
End-of-Year Review
Before the end of the tax year, review your portfolio for positions that are at a loss. Consider whether harvesting those losses makes sense given your overall tax situation.
Ongoing Harvesting
Some investors harvest losses throughout the year whenever they spot significant unrealized losses. This can be more effective than waiting until year-end.
Important Considerations
- Wash sale rules: In some jurisdictions, you cannot sell an asset at a loss and immediately rebuy it. Check if this applies to crypto in your jurisdiction.
- Transaction costs: The tax savings should exceed the trading fees and costs
- Long-term perspective: Do not sell an asset you believe in just for tax benefits — the long-term gains may exceed the tax savings
- Record keeping: Document every transaction for tax reporting purposes
The Sri Lankan Context
Tax-loss harvesting is a well-established strategy in countries with clear crypto tax rules. In Sri Lanka, the tax landscape for crypto is still developing. However, understanding this concept now prepares you for when regulations are clarified. At minimum, keep records of all your losses — they may be valuable in the future.
