The wash-sale rule is a regulation designed to prevent investors from claiming tax benefits on capital losses if they repurchase the same or a substantially identical security within 30 days before or after selling it at a loss. This rule ensures that tax-loss harvesting is not misused to artificially lower tax liabilities while maintaining the same investment position.
Violating the wash-sale rule disqualifies the claimed loss from being deducted on your tax return. Instead, the disallowed loss is added to the cost basis of the repurchased security, affecting future tax calculations.
To comply, investors should either wait for the 30-day window to lapse or reinvest in a different but comparable asset. By adhering to this rule, investors can effectively utilise tax-loss harvesting without facing penalties or complications during tax filings. Understanding the wash-sale rule is crucial for strategic and compliant portfolio management.
