Why multi‑year tax planning matters for high earners
If you are asking how to plan taxes across multiple years, you are already ahead of most high earners. Many wealthy families still treat taxes as a once‑a‑year compliance task instead of a long‑range strategy that shapes how they invest, spend, and transfer wealth.
Multi‑year planning recognizes that your tax life does not reset every January. Decisions you make today affect:
- What bracket you are in next year
- How much future capital gains and income will be taxed
- Whether you qualify for new deductions and credits created by recent laws like the One Big Beautiful Bill Act (OBBBA)
Public Law No: 119‑21, commonly called OBBBA, reshaped the tax environment for 2025, 2026, and beyond, expanding and modifying many Tax Cuts and Jobs Act provisions and creating new opportunities for both individuals and businesses [1]. Multi‑year planning is how you capture those opportunities rather than react to them.
An integrative approach coordinates your investments, business entities, estate planning, and charitable goals around one objective: maximize after‑tax wealth over time, not just minimize this year’s bill.
Build a multi‑year tax planning framework
You cannot optimize across years without a clear framework. That framework needs to anchor your decisions in numbers, not guesswork.
Map your current and future tax picture
Start by projecting your taxable income, bracket, and key thresholds not just for this year, but for at least the next 3 to 5 years.
You will want to account for:
- Base salary and expected bonuses or liquidity events
- K‑1 income from businesses and partnerships
- Expected capital gains from portfolio changes, sales of properties, or business exits
- Retirement account withdrawals and eventual required minimum distributions (RMDs)
- Any planned Roth conversions or deferred compensation payouts
American Century notes that projecting your current year tax bracket with an advisor, especially in late fall, is important because personal tax rates and IRS brackets can change each year, which directly affects the timing and tax impact of your investment moves across multiple years [2].
Once you have a base case, you can model how moving income or deductions between years changes your total tax over the whole period.
Track the rules that affect timing
For high earners, the value of multi‑year planning often comes down to timing. For example, taxpayers who expect similar brackets in 2025 and 2026 may want to defer taxable income to 2026 and accelerate deductible expenses into 2025. Taxpayers who expect higher tax rates in 2026 may do the opposite and accelerate income into 2025 while deferring deductions [1].
New rules that matter for timing include:
- OBBBA’s expanded State and Local Tax (SALT) deduction cap of 40,000 starting in 2025, with income‑based phaseouts and inflation indexing [3]
- A new 0.5% AGI floor on charitable deductions for itemizers beginning in 2026 [1]
- New individual deductions from 2025 to 2028, such as a 6,000 senior deduction, up to 25,000 tips deduction, up to 12,500 overtime deduction, and 10,000 car loan interest deduction, each with income phaseouts [1]
Multi‑year planning is about deliberately aligning income and deductions with these windows.
Use integrative planning instead of siloed decisions
If you are a high earner with significant investments, you probably have:
- A CPA who files returns
- An investment advisor who manages your portfolio
- An attorney for entities and estate planning
In a siloed setup, each professional optimizes their lane. Integrative Planning steps back and asks a different question: how do you structure income, investments, entities, and giving so that your entire system works together tax‑efficiently over time.
For example, it is not enough to know which tax strategies wealthy families use. You need coordinated execution that connects your business cash flows, portfolio design, and estate plan so that strategy actually shows up in your tax return.
Coordinate with key tax law changes
If you want to know how to plan taxes across multiple years, you must plan around known and anticipated law changes instead of being surprised by them.
Use OBBBA’s new SALT and deduction rules
OBBBA increased the SALT deduction cap to 40,000 beginning in 2025 with inflation adjustments and income‑based phaseouts [3]. Duane Morris notes that this higher cap is temporary and is scheduled to revert to 10,000 in 2030 and that the larger deduction phases out at higher incomes [1].
Practical ways to use this multi‑year:
- If your income is below the phaseout range in 2025, you might bunch property tax and state income tax payments into years when the cap is highest and fully available
- If you are close to the phaseout, you may coordinate business and investment income to land just below key thresholds in chosen years
The same logic applies to new deductions like the senior, tips, overtime, and car loan interest deductions. Understanding the income phaseouts lets you manage AGI so those benefits are not unintentionally lost.
Adjust withholdings and estimated payments
OBBBA changes mean many taxpayers will see mismatches between payroll withholding and actual liability in 2025 and 2026 unless they act. HCVT specifically notes that updating withholding is necessary to align with new deductions and SALT limits across tax years [3].
You should:
- Use the IRS Withholding Estimator
- Review and update Form W‑4 when income, family status, or deductions change
- Coordinate estimated tax payments with big investment transactions and liquidity events
The IRS also recommends checking withholding regularly so that you pay appropriate tax throughout the year and avoid underpayment penalties [4].
Plan capital gains and losses across years
For high net worth investors, capital gain and loss planning is often the highest return‑on‑effort strategy in the toolkit.
Treat capital gains as a multi‑year decision
HCVT describes good capital gain and loss planning as one of the highest return‑on‑investment strategies under OBBBA and emphasizes the need to review taxable accounts and retirement distributions for multi‑year tax efficiency [3].
Some decisions you can plan over several years:
- Spreading large gains across tax years to avoid pushing yourself into a higher bracket
- Pairing expected future gains with losses you can realize this year or next
- Coordinating sales with lower income years, such as sabbaticals, business transition years, or early retirement
If you are actively trading or realizing gains, it is worth reviewing broader strategies for how to minimize capital gains tax on investments.
Use tax‑loss harvesting continuously, not just in December
Tax‑loss harvesting lets you sell investments at a loss to offset capital gains in the same year, and if your losses exceed your gains, up to 3,000 of the remaining loss can offset ordinary income, with any unused losses carried forward to future years [5].
Multiple sources highlight how powerful this can be over time:
- CLA notes that loss harvesting can offset current or future gains, and that excess losses carry forward, but cannot be used in tax‑deferred accounts like IRAs and 401(k)s. They also emphasize the need to follow the wash sale rule, which prohibits repurchasing the same or similar security within 30 days [6].
- Morgan Stanley explains that short‑term gains taxed at ordinary income rates can be more effectively offset by harvested losses than long‑term gains taxed at lower rates [5].
- J.P. Morgan Asset Management shows that continuous, year‑round harvesting can generate more savings than a once‑a‑year approach. Their analysis from 2018 to 2021 found that daily tax‑loss harvesting yielded about 30 basis points of additional annualized tax savings on average compared to monthly harvesting [7].
They also note that even in years when the S&P 500 is up strongly, such as a 26% gain in 2023, roughly 30% of stocks finish the year with negative returns and about 75% fall at least 5% from a peak at some point, creating consistent harvesting opportunities [7].
If you want a deeper dive on this tactic, you can review what tax loss harvesting is and whether it is worth it.
Use direct indexing and portfolio design
Direct indexing, in which you own individual securities instead of a single index fund, can open much richer harvesting opportunities because losses can be realized at the individual security level. J.P. Morgan highlights that this structure, paired with daily technology‑driven review, can significantly increase the number of usable losses over time [7].
This is where true integrative planning shows up. You are not just trying to beat a benchmark. You are deliberately designing a portfolio for tax‑aware rebalancing, ongoing harvesting, and long‑term capital gain realization. For a broader foundation, you can also explore how to structure investments for tax efficiency and how to avoid unnecessary taxes on large portfolios.
Structure and shift income across tax years
High earners have more control over when and how income is recognized than typical W‑2 employees. Multi‑year planning uses that flexibility deliberately.
Understand strategic income shifting
EP Wealth Advisors describe income shifting as legally moving income from higher tax environments to lower tax environments. That can mean:
- Reallocating income to family members in lower tax brackets
- Holding certain assets in more favorable accounts
- Deferring income into years when you expect lower tax rates or lower total income [8]
Income shifting can also help you manage cash flow by timing income recognition. For example, you might defer a bonus or capital gain into a year when other income is lower to reduce the combined tax hit [8].
More broadly, these ideas overlap with what tax strategies high earners use and the best strategies for multiple income streams.
Use tax‑advantaged accounts and Roth strategies over several years
Contributions to workplace retirement plans and traditional IRAs reduce current year taxable income and adjusted gross income, which is one of the simplest and most powerful multi‑year planning tools. The IRS specifically highlights these contributions as a way to lower AGI and improve your tax situation across years [4].
EP Wealth Advisors also note that maximizing contributions to tax‑advantaged accounts and utilizing deferred compensation plans can defer taxable income to future years where tax rates may be lower. In lower income years, partial Roth conversions can secure future tax‑free growth by recognizing income strategically when your marginal rate is temporarily reduced [8].
American Century emphasizes that coordinating Roth conversions over multiple years helps spread out the tax liability. Each conversion must be completed by December 31 to count for that year’s taxable income, so multi‑year planning is critical [2].
If you are focused on using investments to lower taxes, you may find it useful to explore how to reduce taxable income with investments and how high net worth individuals reduce taxes legally.
Make charitable giving and legacy strategies multi‑year
Generous families can significantly improve after‑tax outcomes by treating philanthropy and legacy planning as part of their tax system, not separate from it.
Use charitable “bunching” and donor‑advised funds
CLA recommends multi‑year charitable strategies such as:
- “Bunching” contributions by making several years of gifts in one tax year, often through funding a donor‑advised fund (DAF), to maximize itemized deductions
- Taking the standard deduction in off years when you do not bunch
- Donating appreciated securities you have held for more than one year, which may let you deduct fair market value while avoiding capital gains tax [6]
Beginning in 2026, OBBBA will limit charitable deduction benefits through a 0.5% AGI floor, which makes accelerating charitable gifts into earlier years an important multi‑year move if you are charitably inclined [1].
Coordinate RMDs and qualified charitable distributions
For investors with large retirement accounts, RMDs starting at age 73 often push AGI higher in later years, which can also affect Medicare premiums and other thresholds. CLA notes that individuals aged 70½ or older can use qualified charitable distributions (QCDs) to donate up to 108,000 per year directly from an IRA to charity. These QCDs:
- Count toward RMDs
- Are excluded from taxable income
- Can lower AGI and overall tax burden
- May help you qualify for enhanced deductions and credits under OBBBA [6]
Starting in 2023, SECURE 2.0 also allows a one‑time QCD of up to 54,000 from an IRA to certain split‑interest charitable entities, such as charitable remainder trusts or charitable gift annuities. That QCD counts toward your RMD for that year and stays out of taxable income, while also providing lifetime income to you or loved ones [6].
Each of these is inherently multi‑year and works best when coordinated with your broader long‑term giving and estate plan.
Use entities, real estate, and business structures strategically
For many high net worth investors, much of the opportunity sits inside business and real estate structures, not just public markets.
Review entities and ownership regularly
HCVT recommends periodic reviews of entity structures and health‑related financial arrangements in 2026 to ensure they align with updated income levels, ownership changes, and new OBBBA rules. Getting this right can improve both liability protection and tax efficiency across years [3].
This is particularly important if you have:
- Multiple operating companies or professional practices
- Family limited partnerships or holding companies
- Complex income sharing within a family
Integrative Planning can help ensure that your entity design supports your broader goals and coordinates smoothly with your investment and estate plans.
Use cost segregation and real estate depreciation
Real estate is another powerful multi‑year planning tool. HCVT notes that conducting a cost segregation study in 2026 for property placed in service in 2025 can generate accelerated depreciation deductions for 2025. Those deductions may create or increase a Net Operating Loss (NOL) that can be carried forward to offset income in future years [3].
This is a clear example of how a one‑time technical decision can reshape your taxable income trajectory for years. Instead of looking at your real estate in isolation, you can ask how those deductions can be matched with high‑income years or used to offset gains from business or portfolio events.
Operational habits that support multi‑year planning
Advanced strategies only work if you support them with disciplined day‑to‑day practices.
Stay organized and proactive year‑round
The IRS suggests several habits that support year‑round planning:
- Organize tax records throughout the year, using software or clearly labeled folders for income, deductions, and investment documents
- Identify the correct filing status early, and review it after life events like marriage, divorce, birth, or death because status affects filing requirements, the standard deduction, and eligibility for credits
- Understand and actively manage your adjusted gross income, since a higher AGI usually leads to higher total tax and can phase you out of valuable benefits [4]
American Century also emphasizes starting tax planning early in the year rather than waiting until filing season. When you consider tax impacts with each investment decision, you reduce stress and create more room to maneuver before year‑end [2].
They also highlight:
- Using tax‑loss harvesting year‑round, not just at year‑end
- Coordinating the timing of contributions and withdrawals, including making retirement contributions by Tax Day and taking RMDs by December 31 to avoid penalties across multiple years [2]
These practical habits are as important as any advanced tactic because they give you accurate information and enough time to act.
Work with an advisor focused on tax integration
Not every advisor is set up to do genuine multi‑year, tax‑integrated work. EP Wealth Advisors emphasize that suitability and compliance depend on your income structure, jurisdiction, and long‑term goals, and that professional advisory teams are often needed to navigate these layers correctly [8].
If your goal is to systematically improve after‑tax outcomes, it can be useful to ask:
- How does this advisor coordinate with my CPA and attorney in practice, not just in theory
- Do they have a clear process for modeling taxes across several years, not just this one
- How do they help clients reduce taxes on dividends and interest income, capital gains, and multiple income streams in an integrated way
For a broader sense of the value of expert guidance, you can explore how financial advisors help reduce taxes and when you should work with a tax planning financial advisor.
Multi‑year tax planning is not a single tactic. It is an ongoing process that coordinates your investments, income, giving, and entities so that every year builds on the last.
If you are serious about using integrative planning for tax‑efficient wealth structuring, the next step is to bring your CPA, investment advisor, and estate attorney into one coordinated conversation. That is where the real, compounding benefits of planning your taxes across multiple years begin to show up in your net worth.
