Quoted 1.85%, then built the product I actually wanted

A 1.85% advisor quote was the forcing function, but it was not the whole story. What I really wanted was transparent, tax-aware portfolio software that worked on the brokerage I already used. It did not exist, so I built it.

What is tax-loss harvesting? A no-jargon explainer.

Every year the market gives you opportunities to capture losses without changing your investment thesis. Tax-loss harvesting turns those paper losses into real tax value. Here is what it is, how it works, and why direct indexing makes it much more powerful.

The algorithm behind HarvestEngine, and why customers should care

Most tax-loss harvesting tools compete on user interface and minimum account size. HarvestEngine competes on the engine itself: factor-grounded ranking, wash-safe replacement logic, vol-adjusted thresholds, and an audit trail the user can actually inspect.

The math

Tax alpha, fee shape, and the structural differences that change after-tax outcomes.

TLH vs ETF rebalancing: which actually saves you money?

One ETF gives you one place to harvest. A direct-index sleeve gives you many. That structural difference is the simplest honest reason direct indexing exists.

Why subscriptions beat percentage-of-assets fees at $250K and up

The shape of the fee matters more than most investors realize. A subscription stays fixed. A percentage-of-assets fee scales with your wealth forever.

Tax alpha: the return your portfolio earns by paying less tax

Tax alpha is not magic and it is not stock-picking alpha. It is the after-tax improvement that comes from smarter loss harvesting, gain deferral, and lot selection.

When does the AI Designer + tax-loss math justify the $49?

The Sandbox shows you how the engine thinks. Guided is when you bring real money. Here's the threshold where the tax math actually pays the subscription back, and the threshold below which a Vanguard ETF is the better answer.

The rules

Wash sales, basis tracking, and the IRS code sections that decide whether a move is actually clean.

The wash-sale rule, demystified

If you sell at a loss and buy back something substantially identical inside the window, the IRS can disallow the loss. This is the line between smart harvesting and self-inflicted damage.

The step-up basis: why long-horizon tax planning is more powerful than it first looks

Tax-loss harvesting is often described as a temporary deferral. Long-horizon estate rules can make that framing much too simplistic.

The IRS code behind tax-loss harvesting: the practical cheat sheet

You do not need to memorize the whole tax code. You do need to understand the few sections that determine whether a harvest is usable, a hedge is clean, and a long-horizon plan actually works.

Concentrated stock + RSUs: tax planning when one ticker dominates

Concentrated stock is not just a risk problem. It is a risk-and-tax problem at the same time. Here is how direct indexing and pacing make the unwind smarter.

The art of pacing: why timing your harvests through the year matters

TLH is not just about seeing a loss and clicking sell. It is about building a usable loss bank, avoiding bad timing, and realizing gains intentionally when the year is right.

The zero-tax exit: pairing losses with gains for a $0 tax bill

A harvested loss bank is not just this year's tax help. It can become a strategic reserve for future diversification, rebalancing, and liquidity decisions.

Using short positions as escape hatches on risky long bets

Short positions are not only about trying to profit from decline. In the right setup, they can help reshape risk around appreciated long holdings without forcing a crude sell-now decision.

When the long sleeve isn't enough

Long-only TLH is a real win. But for high-income / RSU-heavy / concentrated-stock cases, the long side runs out of harvestable losses before the year does. The short overlay generates additional realized losses without permanently changing your market exposure. Here's the case for it, and the cases against.

Direct indexing in 2026: who needs it, who doesn't

Direct indexing is not for everyone. But for the right taxable account, it creates a much better tax surface than a plain ETF. Here is how to decide where you actually fall.

Short overlay: when extra flexibility is worth the complexity

A short overlay can add risk control and flexibility on top of a long-only tax-aware portfolio. It can also add a lot of complexity fast. Here is when it earns its place and when it clearly does not.

Beta, in plain English: why your portfolio's risk is mostly the market's risk

Beta is the market-sensitivity dial underneath the portfolio. If you do not understand it, you do not fully understand what your portfolio is likely to do in a real drawdown.

The three sleeves: beta, long, and short — and why the structure matters

A serious tax-aware portfolio is easier to understand when you separate clean beta exposure from the long tax-aware sleeve and the optional short overlay.

Margin, demystified: cash, SMA, and why your buying power is bigger than your cash

Open a margin account and your broker hands you four different 'cash' numbers — Investable Cash, Net Cash, Adjusted SMA, Margin Buying Power — and they can differ by 40×. Here's what each one means, when it matters, and why HarvestEngine only shows margin metrics on accounts you've explicitly designated for the short overlay.
