Tax-loss harvesting is one of the most powerful — and most neglected — strategies in financial planning. Done right, it can generate thousands of dollars in annual tax savings. Done wrong (or not at all), you're leaving money on the table.

Alistair's Tax-Loss Harvesting Microtool is a focused coaching experience that walks you through the entire strategy — from understanding what it is to identifying opportunities in your own portfolio — all in a conversation.

What Is Tax-Loss Harvesting?

In simple terms: when an investment in your taxable brokerage account drops below what you paid for it, you can sell it to "realize" the loss. That loss can offset:

  • Capital gains from other investments you sold for a profit (avoiding capital gains tax)
  • Up to $3,000 of ordinary income per year (reducing your income tax bill)
  • Future gains carried forward (unused losses carry forward indefinitely)

After selling at a loss, you immediately reinvest in a similar (but not identical) investment to maintain your market exposure. The IRS wash-sale rule prevents you from buying back the exact same security within 30 days, but a similar ETF or mutual fund is fair game.

What Makes It a Microtool?

Alistair's microtools are small, focused capabilities that solve a specific problem extremely well. Tax-loss harvesting is a perfect example: it's one well-defined strategy that, when you understand it, consistently saves you money.

Here's what the microtool does:

A Guided Conversation

Instead of reading articles and piecing things together yourself, you talk to Alistair about tax-loss harvesting. You describe your holdings — or upload a portfolio statement — and Alistair walks you through the analysis:

  • Are any of your positions currently showing a loss?
  • How much would selling those positions save you, given your tax bracket?
  • Which replacement securities would keep your market exposure intact without triggering a wash sale?
  • Should you prioritize short-term or long-term losses based on your other capital gains this year?

Tax-Aware Calculations

Not every loss is worth harvesting. Selling a position to save $50 in taxes while incurring $30 in trading costs isn't a great trade. Alistair helps you do the math — factoring in your marginal tax rate, the size of the loss, and whether it's a short-term or long-term position.

Short-term losses offset short-term gains first — which are taxed at your ordinary income rate — making them potentially more valuable than long-term losses. Alistair helps you prioritize.

Wash-Sale Guidance

The IRS wash-sale rule says you can't buy a "substantially identical" security within 30 days before or after the sale. Alistair helps you find replacement securities that keep your market exposure intact while staying clear of the rule.

For example:

  • Sell a broad-market US stock ETF → Consider a different broad-market US stock ETF
  • Sell a technology-heavy position → Consider a broad sector ETF
  • Sell a total bond market fund → Consider an intermediate-term bond fund

Scenario Planning

Alistair doesn't just explain the concept — it models it for your situation. Sold a rental property in February and realized a big capital gain? Alistair helps you figure out how much in losses you'd need to harvest to offset it before year-end. Planning a Roth conversion? It factors that in too.

Real Numbers: What It's Worth

Let's walk through a realistic scenario:

  • Taxable brokerage balance: $500,000
  • Average market volatility: 15% annual drawdown at some point during the year
  • Harvestable losses discussed with Alistair: $7,500 (conservative estimate)
  • Tax bracket: 32% federal + 5% state = 37% combined

If those $7,500 in losses offset short-term gains or ordinary income, the tax savings are approximately $2,775 per year.

That's real money — and it compounds. Reinvested at 7% for 20 years, $2,775 per year grows to over $120,000. Just from a strategy Alistair can walk you through in a single conversation.

Why Advisors Miss This

If tax-loss harvesting is so valuable, why don't all advisors do it religiously? Three reasons:

  1. It's tedious. Monitoring tax lots, checking wash-sale windows, and calculating optimal trade sizes for 80+ clients is a full-time job. Most advisors don't have the bandwidth.

  2. It doesn't generate revenue. Advisors get paid on AUM. Tax-loss harvesting reduces your tax bill — which is valuable — but doesn't grow the advisor's fee base directly. There's no incentive to prioritize it.

  3. It requires proactive effort. The best harvesting opportunities don't announce themselves. Someone has to go looking. Quarterly review cycles rarely catch them.

The Alistair Advantage

The Tax-Loss Harvesting Microtool doesn't require you to schedule a meeting, wait for a callback, or hope your advisor remembers to check. You start the conversation when you're ready, describe your situation in plain English, and get a personalized analysis — mathematical, wash-sale-aware, and tailored to your actual positions.

No account linking required. No transferring your money. Just a conversation that could save you thousands.

That's why we build microtools: because the financial industry is full of valuable strategies that get ignored — not because they're hard, but because they're a hassle. We make them easy.

Your tax bill doesn't have to be what it is. That's what microtools are for.
