Year-End Tax Planning for Accredited Investors: The Moves to Make Before December 31
In the Air Force, the worst time to plan a mission is during the mission. Every good outcome traces back to preparation that happened well before anyone stepped onto the flight line. Tax planning works the same way, and yet most investors treat it like an April problem instead of a fourth-quarter discipline.
By the time your CPA is preparing your return, the window for most meaningful tax strategy has already closed. The moves that actually reduce what you owe almost all have to happen before December 31. So let's use the time you still have this year and go through what belongs on your list.
Why Year-End Planning Matters More for Accredited and High Net Worth Investors
If you're an accredited investor with real estate holdings, business income, or a diversified portfolio, your tax picture is more complex than a standard W-2 filer's, and that complexity cuts both ways. It creates more opportunity for strategic planning, and more risk of leaving money on the table if you wait until the return is already being prepared.
A few reasons this population specifically needs a proactive year-end process:
Multiple income sources, rental income, capital gains, business income, often need coordinated planning rather than one-off decisions
Higher income levels mean more exposure to additional taxes like the Net Investment Income Tax
Real estate holdings involve timing decisions, sales, exchanges, and cost segregation studies… that only work if executed within the tax year
Access to strategies like DST investments and Qualified Opportunity Funds that aren't available to the general investing public
Review Your Realized Gains and Losses
Start with a clear picture of what's already happened this year. Have you sold any property, securities, or other appreciated assets? Do you have unrealized losses elsewhere in your portfolio that could offset those gains?
Tax loss harvesting involves selling underperforming positions to realize losses that offset realized gains elsewhere, reducing your overall taxable income for the year. This needs to happen before December 31, and it requires coordination with your overall investment strategy, not a rushed decision in the final week of the year.
Evaluate Any Pending Real Estate Sales
If you're considering selling investment property, timing matters more than most people realize.
Selling before year-end versus after can shift your capital gain into a different tax year, which matters if your income, and therefore your tax bracket, is expected to be meaningfully different next year.
If you're planning a 1031 exchange, make sure your Qualified Intermediary and replacement property strategy are lined up well before you close, since the 45-day identification clock starts the moment your sale closes, regardless of the calendar.
Depreciation and cost segregation. If you've recently acquired investment property, a cost segregation study can accelerate depreciation deductions into earlier years, potentially generating a larger deduction this year if completed before year-end. This is a technical strategy that requires a qualified engineer or specialist, not something to attempt informally.
Understand Your Net Investment Income Tax Exposure
The Net Investment Income Tax, an additional 3.8% federal tax, applies to certain investment income, including rental income, capital gains, and other passive income, for taxpayers above specific modified adjusted gross income thresholds.
For real estate investors, this tax can apply to:
Capital gains from selling investment property, above and beyond standard capital gains tax
Rental income, if the activity is considered passive rather than a real estate professional's active trade or business
Interest, dividends, and other investment income across your broader portfolio
A few considerations worth discussing with your CPA before year-end:
Whether income timing adjustments could keep you under relevant thresholds in a given year
Whether real estate professional status applies to your situation, which can change how certain rental income is treated
How a 1031 exchange, by deferring the recognized gain, also defers the NIIT exposure tied to that gain
This is a tax that catches high-income real estate investors off guard more often than it should, largely because it layers quietly on top of standard capital gains calculations rather than showing up as its own clearly labeled line item until the return is prepared.
Maximize Retirement Account Contributions
This is one of the more straightforward year-end moves, and it's often underutilized by investors focused primarily on real estate.
Confirm you've maximized contributions to any available retirement accounts, 401(k), SEP IRA, solo 401(k) if you have self-employment or business income, before relevant deadlines.
If you're self-employed or have business income tied to your investment activities, a SEP IRA or solo 401(k) can allow for substantially higher contribution limits than a standard employer plan, which can meaningfully reduce current-year taxable income.
Required minimum distributions, if applicable to your situation, need to be taken before year-end to avoid penalties.
Consider Charitable Strategies
For accredited and high-net-worth investors, charitable giving can serve both a values-based purpose and a tax efficiency purpose, particularly when it comes to faith and family priorities many of my clients hold close.
Donating appreciated securities or real estate directly, rather than cash, can allow you to avoid recognizing the capital gain while still receiving a charitable deduction for the fair market value, subject to applicable limits.
Donor-advised funds allow you to make a charitable contribution and take the deduction in the current year, while distributing the funds to specific charities over a longer timeframe.
Qualified charitable distributions, if applicable to your age and account type, can allow charitable giving directly from an IRA in a tax-efficient manner.
Evaluate Qualified Opportunity Fund Investments
If you've realized significant capital gains this year, from a business sale, a stock position, or real estate, investing those gains into a Qualified Opportunity Fund within the required timeframe may offer deferral and potential reduction benefits under current law, subject to specific holding period requirements. This is a complex, fact-specific strategy that requires careful review with your tax advisor, particularly around the applicable deadlines tied to when the original gain was realized.
Review Your Entity and Income Structuring
For investors with multiple properties or business interests, year-end is the time to review:
Whether your current entity structure LLC, S corp, partnership, is still optimal for your holdings and income level
Whether income and expenses can be reasonably timed between this year and next to manage bracket exposure
Whether estimated tax payments are on track to avoid underpayment penalties
A Year-End Planning Checklist
Review realized gains and losses, and evaluate tax loss harvesting opportunities
Assess any pending real estate sales and whether timing or a 1031 exchange changes your outcome
Calculate your Net Investment Income Tax exposure and discuss mitigation strategies with your CPA
Maximize retirement account contributions available to you
Evaluate charitable giving strategies, including appreciated asset donations and donor-advised funds
Review Qualified Opportunity Fund eligibility if you've realized significant gains this year
Confirm your entity structure and estimated tax payments are on track
Schedule a coordinated conversation with your financial advisor, CPA, and attorney before December 31, not after
Why This Requires a Team, Not a Solo Effort
None of these strategies work well in isolation, and most of them interact with each other. A 1031 exchange decision affects your NIIT exposure. A charitable giving strategy affects your overall taxable income, which affects which bracket your other decisions land in. This is exactly why year-end planning benefits from a coordinated conversation between your financial advisor, CPA, and attorney, rather than each professional working from a different piece of the picture.
The investors who consistently minimize their tax exposure year over year aren't smarter than everyone else. They're simply more disciplined about having this conversation in October and November instead of March.
