FAQPage Schema
How do I identify unrealized losses for tax-loss harvesting in my portfolio?

Identify tax-loss harvesting opportunities by analyzing unrealized losses across taxable accounts to realize losses that offset capital gains and optimize after-tax returns. The process outputs candidate lists of securities holding unrealized losses for execution.

What is a wash sale and how do I track wash-sale windows?

A wash sale occurs when you repurchase a substantially identical security within a restricted window. Tracking wash-sale windows ensures you avoid disallowed losses by monitoring replacement security transactions across the required timeframe.

How do I maintain market exposure while replacing securities to avoid wash sales?

Maintain market exposure by selecting replacement securities that preserve your original asset allocation without triggering wash sale rules. The system proposes compliant replacement options that keep your portfolio invested while realizing the tax loss.

Can I estimate tax savings before executing a tax-loss harvesting plan?

Estimate tax savings by calculating the potential offset value of realized losses against your capital gains. The output includes computed potential tax savings alongside the candidate lists and replacement suggestions to guide your execution.

What is the best way to generate a tax-loss harvesting execution plan?

The best way to generate an execution plan is to aggregate unrealized losses, match them with compliant replacement securities, and track wash-sale windows. This yields a structured execution plan and post-harvest tracking output to optimize after-tax returns.

When should I not use tax-loss harvesting in taxable accounts?

Avoid tax-loss harvesting when wash-sale windows prevent effective replacement security selection or when unrealized losses are insufficient to generate meaningful tax savings. Limitations arise if maintaining precise market exposure is not feasible without violating wash-sale rules.
