The U.S. tax code runs to nearly 75,000 pages, and most of what determines how much you actually pay has nothing to do with the headline bracket you’re in. It comes down to which of three taxes applies, whether you’re looking at your marginal rate or your effective rate, and which of a handful of proven strategies you’re actually using.
Part of our guide: Crypto Taxes.
Three taxes, not one
Higher-net-worth investors deal with three separate taxes on investment activity. Income tax runs on the marginal system most people know: as your income rises, only the income above each threshold gets taxed at the higher rate, not your entire income retroactively. Capital gains tax applies when you sell an appreciated asset for more than you paid, and it only triggers on a sale, not simply because an asset went up in value while you held it. How long you hold matters enormously: sell within a year and the gain is taxed at your ordinary income rate; hold past a year and it drops to the long-term capital gains rate. Third, the net investment income tax adds a 3.8% surtax on interest, dividends, capital gains, and rental income once your modified adjusted gross income crosses roughly $200,000 single or $250,000 married, thresholds worth confirming for the current tax year.
Capital losses can offset capital gains, and unused losses carry forward into future tax years, which is the foundation for one of the more useful strategies below.
Marginal rate versus effective rate, and why the difference matters
Your bracket is not what you actually pay. A couple with $500,000 in taxable income sitting in the top marginal bracket doesn’t send close to 40% of their income to the IRS; they pay that top rate only on the slice of income above the threshold for that bracket. Add up the tax owed at each bracket and their effective rate, the number that actually matters, lands well below the marginal rate. This is also why tax planning targets your marginal rate: a strategy that shields $20,000 of income taxed at your top bracket saves you more than the same $20,000 would save at your effective rate, because that income was sitting at the top of the stack.
Tax loss harvesting is the most accessible strategy
Selling a position that has lost value to offset gains elsewhere in your portfolio is available to almost anyone with a taxable account, and it adds up. Say you bought a stock for $200,000 two years ago and it’s now worth $190,000. Selling it locks in a $10,000 loss you can apply against gains from other positions, reducing your taxable gain dollar for dollar. If losses exceed gains for the year, up to $3,000 can offset ordinary income, and anything beyond that carries forward to future years.
The catch is the wash sale rule: you can’t claim the loss if you buy the same security, or something substantially identical, within 30 days before or after the sale, a 61-day window in total. Individual stocks aren’t considered identical to each other, so selling Home Depot at a loss and buying Lowe’s the same day is fine. Selling one S&P 500 index fund and buying another the next day is not.
Asset location matters as much as asset allocation
Where you hold an investment can matter almost as much as what you hold. Interest income is taxed at your marginal rate regardless of account type, while long-term capital gains and qualified dividends get the lower capital gains rate. That makes taxable brokerage accounts a reasonable home for equities that generate most of their return through appreciation, since gains there qualify for the lower rate and losses are easy to harvest. Bonds and other income-generating holdings that throw off regular taxable distributions are usually better sheltered in tax-advantaged accounts, where that income can compound without an annual tax bill.
Beyond the basics
For investors with concentrated stock positions, exchange funds let you pool a large single-stock holding with other investors’ concentrated positions in exchange for diversified fund shares, without triggering the capital gains bill a straight sale would create. An options collar accomplishes something similar for investors who want to keep a position: selling a call and using the premium to buy a put brackets the price range without forcing a sale. Employees with appreciated company stock in a 401(k) should ask about net unrealized appreciation treatment before rolling that stock into an IRA, since it can shift part of the gain from ordinary income rates to the lower capital gains rate.
None of these strategies are do-it-yourself projects. Get your CPA, tax attorney, and financial advisor working from the same picture of your holdings before you touch any of them.
