Tax Loss Harvesting and Capital Gains Planning

Capital gains planning for Naples investors

We see this scenario often with Naples small business owners. A successful season for local contractors or Fifth Avenue South restaurateurs often leads to an unexpectedly large tax bill.

It is frustrating to work hard all year only to lose a massive chunk of your profits to taxes. Our professional service team has noticed that investment tax quietly becomes the largest annual line item for many Southwest Florida professionals.

When calculating your capital gains tax, Naples business owners realize that proactive planning changes the outcome.

You can drastically reduce what you owe the IRS by coordinating your business exits and stock sales. We are going to break down the mechanics of tax loss harvesting capital gains for the 2026 tax year.

Let us look at the latest tax brackets, explain the rules you must follow, and explore practical ways to keep more of your hard-earned wealth.

Long-term vs short-term: the foundational distinction

The holding period determines your tax rate. Assets held for one year or less face short-term capital gains taxes, while those held longer qualify for much lower long-term rates.

We always warn clients that short-term capital gains are taxed as ordinary income. Your top marginal rate could easily hit 32%, 35%, or 37% if you have a highly profitable year.

Long-term capital gains receive preferential treatment from the IRS. The 2026 tax brackets offer significant savings for married couples filing jointly (MFJ).

2026 Taxable Income (MFJ)	Long-Term Capital Gains Rate
$0 to $98,900	0%
$98,901 to $613,700	15%
Over $613,700	20%

Our accountants report these sales on IRS Form 8949. Proper reporting ensures you capture that massive difference of up to 22 percentage points between the short-term and long-term rates. Holding periods matter immensely for your bottom line.

Tax-loss harvesting basics

Tax-loss harvesting means realizing capital losses to intentionally offset your capital gains. This strategy directly lowers your taxable income for the year.

We frequently use this approach to soften the tax blow after a strong market run. The mechanics are straightforward when you break them down step by step.

• You identify realized gains in your portfolio this year, such as $50,000 in profits.
• You then sell specific positions currently sitting at a loss, like $30,000 in underwater stocks.
• Your net taxable capital gain becomes $20,000 instead of $50,000.
• This move saves you roughly $4,500 to $6,000 depending on your specific tax bracket.

Our advisors recommend this even if you do not have current gains. You can use up to $3,000 of net capital losses to offset ordinary income each year. The IRS allows you to carry any remaining losses forward indefinitely to future tax years.

Modern brokerage platforms like Charles Schwab and Fidelity offer zero-commission trades. This elimination of transaction fees makes harvesting even small losses highly cost-effective.

The wash-sale rule

You cannot claim a tax deduction if you buy a “substantially identical” security within 30 days before or after the sale. The IRS strictly enforces this 61-day window under the wash-sale rule.

We carefully monitor trade dates to ensure compliance. The penalty for violating this rule is that your loss gets disallowed and added to the cost basis of the new shares.

Here are practical examples of what is currently allowed:

• Sell the Vanguard S&P 500 ETF (VOO) and buy the Schwab S&P 500 ETF (SWPPX).
• Sell the SPDR S&P 500 ETF (SPY) and replace it with the iShares Core S&P 500 ETF (IVV).
• Sell an individual stock and purchase a broader sector ETF.
• Sell a position, wait 31 full days, and then repurchase it.

Our system also flags trades that the IRS will definitely reject. You must avoid these specific scenarios.

Here are examples of what is strictly not allowed:

• Sell Tesla shares and immediately buy Tesla stock back the next morning.
• Sell at a loss in your taxable brokerage account and buy the exact same asset in your IRA on the same day.
• Trade options contracts on the exact same underlying stock you just sold at a loss.

Sophisticated investors structure their tax-loss harvesting using careful ETF pairs. This method maintains your market exposure while harvesting losses cleanly and legally.

Long-term gain timing

Timing when to realize gains matters just as much as timing your losses. For Naples retirees and business owners nearing an exit, scheduling your sales across different tax years is critical.

We analyze your income projections to find the optimal tax windows. Several strategic considerations can drastically reduce your lifetime tax burden.

Strategic Timing Scenarios

Our planning process focuses on these four key timing opportunities. Each approach targets a specific phase of your financial lifecycle.

• Gain harvesting in a low-income year. You pay $0 in federal taxes if your taxable income sits below $98,900 for a married couple in 2026. This is incredibly useful during gap years between retirement and claiming Social Security.
• Utilizing the standard deduction. The standard deduction provides a generous buffer. This effectively means a married couple could earn well over $100,000 in combined income and gains without paying any federal capital gains tax.
• Deferring gains until retirement. You can save the difference in tax rates by holding highly appreciated assets until your income drops after you stop working.
• Roth conversion timing. You must carefully coordinate Roth conversions with your gain realizations. Conversions increase your taxable income and can accidentally push your capital gains into a higher bracket.

Naples and Florida-specific advantages

Florida residents enjoy zero state income tax on their investment profits. This provides a massive financial edge compared to high-tax states where local taxes stack on top of federal rates.

We help many clients relocate here to protect the proceeds of a major business sale. The geographical savings are substantial when dealing with seven-figure exits.

• No state income tax. Residents of California currently face state capital gains taxes of up to 13.3% or 14.4%, while New York and New Jersey also take a heavy cut. Florida residents keep that entire portion.
• Florida domicile. Proving your intent to stay is one of the most powerful tools for managing a large stock sale. See how to establish Florida residency to ensure your new status is legally bulletproof.
• QSBS treatment. Section 1202 allows founders to exclude up to 100% of the gain from selling Qualified Small Business Stock. The IRS caps this exclusion at $10 million or 10 times your adjusted basis, making it incredibly lucrative when paired with Florida’s zero state tax environment.

Net Investment Income Tax (NIIT)

The Net Investment Income Tax is an additional 3.8% federal surtax on your investment earnings. It applies when your Modified Adjusted Gross Income (MAGI) crosses specific IRS thresholds.

We factor this hidden tax into every projection because it catches many successful professionals off guard. The thresholds are strictly set at $250,000 for married couples filing jointly and $200,000 for single filers.

These NIIT thresholds are not indexed for inflation. This means wage growth pushes more Southwest Florida taxpayers into this surtax bracket every single year.

Calculating the Surtax Impact

Our tax specialists calculate this liability using IRS Form 8960. The surtax stacks directly on top of the 15% and 20% long-term capital gains rates. This combination means your effective federal rate can quickly reach 23.8%.

You can avoid NIIT exposure by strategically shifting investments. Interest from tax-exempt municipal bonds does not count as investment income under these specific IRS rules.

Coordination with retirement planning

Capital gains timing is most effective when integrated with your comprehensive retirement strategy. Managing your tax brackets requires looking at all your income sources simultaneously.

We look at the big picture to prevent one financial move from triggering unintended tax consequences elsewhere. Proper investment tax planning in Florida requires perfect synchronization.

Key Planning Synergies

Our advisors focus on these four critical areas of coordination. Each element plays a major role in your final tax outcome.

• Withdrawal sequencing. You must thoughtfully decide which accounts to tap first among your taxable brokerage, tax-deferred 401(k)s, and tax-free Roth accounts.
• Roth conversions. Executing these transfers during low-income years maximizes tax efficiency before required minimum distributions begin.
• RMD planning. The SECURE 2.0 Act pushed the starting age for Required Minimum Distributions to 73. This creates a longer, highly valuable window for tax-smart asset shifting.
• Charitable giving. Donating highly appreciated stock directly to a Donor-Advised Fund (DAF) is far superior to giving cash. You eliminate the capital gains tax entirely and still get the full fair market value deduction.

See our Financial Planning service for the full coordination details.

When tax-loss harvesting is and isn’t worth it

Tax-loss harvesting is highly valuable when you have significant realized gains to offset. It becomes less useful, and sometimes counterproductive, in low-income tax brackets or with tiny loss amounts.

We always run a cost-benefit analysis before executing these trades. The math must justify the effort and the minor changes to your portfolio allocation.

When the Strategy Makes Sense

Our experience shows this tactic is highly beneficial in these situations. You should strongly consider it when these conditions align.

• You have large, realized gains during the current year from selling a business or property.
• You hold sufficient unrealized losses in your portfolio to make a meaningful dent in your tax bill.
• You sit comfortably above the 15% long-term capital gains bracket, ensuring the tax savings are substantial.

When to Avoid the Strategy

Our team advises against harvesting losses in these specific scenarios. The drawbacks severely outweigh the benefits here.

• The 0% bracket. You gain nothing by harvesting losses if you are currently in the 0% long-term capital gains bracket. You would essentially waste a valuable tax deduction to save zero dollars.
• Small dollar amounts. The strategy is generally not worth your time if the potential tax savings fall below your transaction costs.
• Future gain timing. It is a mistake to harvest a loss now if you need that specific asset to offset a much larger, unavoidable gain planned for next year.
• Robo-advisor conflicts. Automated platforms like Betterment harvest losses automatically, but they cannot see your outside accounts. This blindness frequently triggers accidental wash sales if you hold similar funds elsewhere.
