How Do High Earners Reduce Investment Taxes?

The opportunity sits in three places: which account holds which asset, when you realize gains, and what you do with losses. High income also triggers an extra tax on investment income and phases out deductions others get, which changes the order in which moves make sense. No single tactic does much on its own.

At some point your tax return got too big to follow, and nobody ever walked you through it. It arrives from your CPA as a stack with a number at the bottom, the number is large, and the conversation about it happens in April when every decision that produced it is already final. You sign, you pay, and you go back to work with a vague sense that some of it was avoidable.

The frustrating part is that you're doing the things you were told to do. You max the 401(k), you hold index funds, you don't trade much. And yet a strong year in the market produces a tax bill that feels disconnected from any decision you remember making, because most of what drives it was set months earlier by where your assets sit and what got sold. That's the part we can help with.

Asset location: which account holds what

Most households own a reasonable mix of investments and hold them in the wrong places. The idea is straightforward. You have accounts taxed three different ways, and every asset you own has a tax character. Matching them deliberately changes your after-tax result without changing your investment mix at all.

Investments that pay income taxed at ordinary rates drag in a regular brokerage account. That means taxable bonds, REITs (funds that own income-producing real estate), and funds that trade a lot. Broad equity index funds are relatively tax-efficient because they distribute little and their qualified dividends and long-term gains get preferential rates. Roth accounts, where future growth is generally never taxed, are often where people put whatever they expect to grow most over the longest stretch.

None of that is a rule to apply blindly. It interacts with what you'll need to spend from, when, and what your bracket will look like then. But it's one of the few adjustments available that doesn't require you to give anything up, which is why we like it.

Controlling when gains show up

A gain becomes taxable when you realize it, which means the timing is largely yours. Holding more than a year moves a gain from ordinary rates to long-term capital gains rates, a substantial difference for anyone in a high bracket. That single distinction accounts for a lot of avoidable tax.

Beyond the holding period, look for the years when realizing gains costs you less. A sabbatical, a year between jobs, a slow year in a commission business, or the stretch between retiring and the age when required distributions begin can all be windows where your income is temporarily lower. If you know a low-income year is coming, plan for it rather than discovering it in hindsight.

Two other mechanisms deserve a mention. Giving long-term appreciated shares to charity or a donor-advised fund generally allows a deduction at current value with no gain recognized, which beats selling and donating cash. And assets held until death generally get a basis adjustment for heirs, so deciding which appreciated positions to sell and which to hold has an estate dimension as well as a tax one.

Losses are an asset if you actually use them

A position that's declined can still do work for you. Selling it realizes a capital loss, which offsets realized gains, and unused losses carry forward indefinitely for individuals, with a limited amount available each year against ordinary income. Reinvesting the proceeds into something similar but not substantially identical keeps you invested while banking the loss.

The constraint is the wash sale rule. Buying the same or a substantially identical security within 30 days before or after the sale disqualifies the loss, and the rule reaches across your accounts. Buying the replacement inside an IRA is the version that hurts most, because the loss isn't deferred there. It's gone. Automatic dividend reinvestment trips people up too.

Harvesting works best as an ongoing habit rather than a December scramble. We've watched the December scramble. It isn't pretty. By year end, most of the opportunities have passed. There are strategies built to harvest automatically, like direct indexing, where you own the individual stocks in an index instead of the fund. They cost more and add moving parts, so judge them on the whole package, not the tax feature.

The thresholds that change the math at high income

A number of provisions in the tax code switch on above income levels that high earners cross regularly, and most of them are invisible until they hit. Knowing which ones are near matters more than knowing their exact figures, because your CPA has the current figures and you have the ability to change your income.

An additional tax applies to net investment income once modified adjusted gross income passes a threshold, which effectively raises the rate on your interest, dividends, and capital gains. Medicare premiums for Part B and Part D carry income-related surcharges based on your return from two years earlier, so one big realization can raise your premiums later. Incentive stock option exercises can pull you into the alternative minimum tax. Various deductions and credits phase out as income rises. And for business owners, the qualified business income deduction has its own thresholds and limitations tied to the type of business.

The practical takeaway is about sequencing. When you're near a threshold, the order and the year in which you take actions matter as much as the actions themselves. That's an October conversation, not an April one.

When a tax move is the wrong move

The objective is keeping more of what you earn over your lifetime. Tax reduction serves that goal most of the time, and the two come apart more often than the industry admits. We regularly meet people holding a dangerously concentrated position for years because selling would trigger a gain. That's the tax tail wagging the portfolio. A concentrated position that falls hard costs more than the tax on selling it ever would have.

The same logic applies to products sold mainly on their tax treatment. Illiquid investments, complex insurance structures, and partnerships marketed around deductions can all be defensible in the right situation, and all deserve a hard look at fees, liquidity, and who's being paid to recommend them. Our filter: if the tax benefit is the main reason the thing exists, ask whether you'd want it at all if the tax code changed. It has before.

What to do next

  1. Pull a list of every investment account you own with its tax treatment and holdings, and look at whether your bond and REIT exposure sits in taxable accounts.
  2. Ask your CPA which thresholds you're closest to crossing this year, and get that answer before the fourth quarter while there's still time to act on it.
  3. Book a 20-minute introductory call. We coordinate with your CPA on the planning side, so decisions get made during the year rather than reported after it.

Frequently asked questions

Does Florida's lack of a state income tax change my strategy?

It removes one lever and raises the value of the others. With no state tax to plan around, federal brackets, holding periods, account placement, and the timing of big realizations carry proportionally more weight. In-state municipal bonds also lose the state tax advantage that motivates them elsewhere, so for a Florida resident the comparison is federal-only. Families who moved here from a high-tax state usually need the old plan revisited.

Is a Roth conversion worth it at a high income?

Sometimes, and it's genuinely situational. A conversion recognizes income now in exchange for tax-free growth later, so it tends to look better when your current bracket is lower than the one you expect and when you can pay the tax from outside the account. It looks worse when it pushes you across a threshold or the tax has to come out of the converted balance. There's no general answer, only your numbers.

What is a backdoor Roth, and can I do one?

It means making a non-deductible contribution to a traditional IRA and converting it to a Roth, which some high earners use because direct Roth contributions phase out above certain incomes. The complication is the pro-rata rule: the conversion is taxed based on the combined balance of all your traditional, SEP, and SIMPLE IRAs, so existing pre-tax IRA money can make the result messy. Work it out with your CPA before you execute.

Do municipal bonds make sense for me?

Municipal bond interest is generally exempt from federal income tax, so the right comparison is a taxable-equivalent yield against a comparable taxable bond at your marginal rate. Some munis are subject to the alternative minimum tax, and credit quality varies a lot by issuer. The answer depends on your bracket and which account the bonds would sit in.

How do you actually work with my CPA?

With your permission, we share the planning information that affects your return, flag realizations and contributions during the year, and get on a call before year end rather than trading emails in April. We don't prepare returns or give tax advice. The point is that whoever prepares your return shouldn't be seeing your decisions for the first time after they're final.
