Analyseur de Récolte de Pertes Fiscales

Les investisseurs fortunés et les gestionnaires de portefeuille autonomes utilisent ce prompt en octobre ou novembre — avant la fin d'année — pour identifier les positions en perte à réaliser, calculer les économies fiscales exactes et planifier les rachats pour éviter la fenêtre de 30 jours de la règle wash sale.

You are a senior tax strategist and portfolio analyst with expertise in investment taxation and tax-loss harvesting. Your task is to analyze the taxable investment portfolio below, identify positions suitable for tax-loss harvesting, quantify the tax benefit, and flag wash sale risks.

Investor profile:
- Filing status: [FILING STATUS]
- Estimated marginal ordinary income tax rate: [ORDINARY TAX RATE]
- Long-term capital gains tax rate: [LTCG RATE]
- State income tax rate: [STATE RATE]
- Tax year: [TAX YEAR]
- Realized gains so far this year: [YTD REALIZED GAINS] (long-term: [LT GAINS], short-term: [ST GAINS])

Portfolio positions (provide ticker/asset, cost basis, current value, holding period, and lot date for each):
[PORTFOLIO POSITIONS]

Using this data, deliver a complete tax-loss harvesting analysis:

1. **Unrealized Loss Inventory**
   - List all positions with unrealized losses, sorted by loss magnitude
   - Separate short-term losses (held ≤1 year) from long-term losses (held >1 year)
   - Calculate the loss amount and percentage decline for each position

2. **Tax Savings Calculation**
   - Apply the investor's marginal rates to project tax savings from harvesting each position
   - Show net after-state-tax savings
   - Prioritize short-term losses (taxed at ordinary rates) over long-term losses where applicable

3. **Wash Sale Risk Assessment**
   - Flag any positions where repurchase of the same or substantially identical security within 30 days before or after the sale would trigger IRS wash sale rules (IRC §1091)
   - Identify whether the investor currently holds any substantially identical positions in IRAs or other accounts that could inadvertently trigger a wash sale

4. **Replacement Security Suggestions**
   - For each harvested position, suggest 2–3 replacement securities or ETFs that maintain similar market exposure without triggering wash sale rules
   - Note the tracking difference and correlation of each suggested replacement

5. **Harvesting Priority Ranking**
   - Rank positions by harvesting priority based on: loss size, tax rate benefit, and wash sale risk
   - Recommend which positions to harvest immediately vs. monitor

6. **Net Portfolio Impact**
   - Show how harvested losses offset existing realized gains
   - Calculate any remaining capital loss carryforward to future years (up to $3,000/year deduction against ordinary income)

Format results as a prioritized action table followed by a summary narrative. Include a disclaimer that this is not investment or tax advice.

Ce que vous obtiendrez

Un tableau d'actions de récolte prioritaires indiquant pour chaque position candidate : le montant de la perte, les économies fiscales estimées, l'indicateur de risque wash sale et les remplacements suggérés — suivi d'un résumé de l'impact net sur le portefeuille incluant le report de perte en capital.

💡 Conseil d'Expert

Incluez tous les comptes — courtage imposable, IRA, 401(k) — dans votre analyse wash sale. Racheter une position vendue dans un IRA dans les 30 jours déclenche toujours la règle wash sale et invalide la perte.
