7 best retirement tax strategies for high-income earners in 2025

Retirement planning for high-income earners requires a careful tax strategy to preserve wealth and optimize savings. Without proper planning, taxes can erode a significant portion of retirement income. By leveraging tax-efficient strategies, you can minimize liabilities and maximize financial growth.

Tax laws evolve, and 2025 presents new opportunities for high-income individuals to refine their tax strategies. Traditional retirement savings accounts, Roth conversions, charitable giving, and alternative investments can all contribute to tax-efficient wealth accumulation. Combining these strategies ensures sustainable financial security in retirement.

Advancements in AI-powered tax solutions, like Mezzi, simplify complex tax optimization processes. With tax-loss harvesting advice, strategic asset allocation suggestions, and AI-driven insights, Mezzi AI helps investors implement effective retirement tax strategies with minimal effort. 

Let’s explore the best ways to lower your tax burden in 2025.

1. Fully fund tax-advantaged accounts

Maximizing contributions to tax-advantaged accounts reduces taxable income while securing future retirement savings. The IRS has set updated contribution limits for 2025:

  • 401(k) and 403(b) Plans: Employees can contribute up to $23,500, with an additional $7,500 catch-up contribution for those over 50.
  • Traditional and Roth IRAs: Contribution limits remain at $7,000, with a $1,000 catch-up option for those aged 50 and above.
  • Health Savings Accounts (HSAs): If enrolled in a high-deductible health plan, individuals can contribute up to $4,300, with a $8,550 limit for families.

Utilizing Mezzi Wealth ensures strategic fund allocation, helping you balance pre-tax and post-tax accounts efficiently. AI-driven insights help optimize withdrawals and contributions for maximum tax efficiency.

2. Consider a Roth conversion

A Roth IRA conversion can be a powerful tax strategy if managed correctly. Converting a traditional IRA to a Roth IRA means paying taxes now to enjoy tax-free withdrawals in retirement.

  • Avoid higher tax rates later: Tax brackets may rise, making pre-paying taxes in a lower bracket advantageous.
  • No Required Minimum Distributions (RMDs): Unlike traditional IRAs, Roth IRAs allow tax-free growth without mandatory withdrawals at 73.
  • Tax diversification: A mix of tax-free and tax-deferred accounts allows for better retirement tax planning.

3. Add money to a 529 account

A 529 plan offers tax-free growth when used for qualified education expenses. High-income earners can use this as an estate planning tool while securing educational funding for children or grandchildren.

  • State tax deductions: Many states provide deductions for contributions.
  • Estate planning benefits: Contributions qualify for the annual gift tax exclusion of $18,000 per beneficiary in 2025.
  • Superfunding strategy: You can contribute up to five years’ worth ($90,000 per beneficiary) in a single year to reduce taxable estate size.

4. Donate more to charity

Charitable donations offer tax benefits while supporting causes you care about. Save on taxes before year-end by leveraging strategic philanthropy, which can lower taxable income through deductions and specialized giving techniques.

  • Donor-Advised Funds (DAFs): Front-load charitable contributions to maximize deductions while spreading donations over time.
  • Qualified Charitable Distributions (QCDs): For retirees aged 70½ and older, direct IRA donations avoid taxable income.
  • Appreciated stock donations: Donating stocks instead of cash allows for capital gains tax avoidance while taking full value deductions.

5. Review and adjust your asset allocation

Proper asset placement minimizes taxable investment income. Tax-efficient investing involves structuring your portfolio to maximize after-tax returns. Reduce your capital gains and income tax by strategically placing tax-efficient investments in taxable accounts and keeping high-yield assets in tax-advantaged retirement accounts.

  • Tax-efficient investments in taxable accounts: Favor ETFs and municipal bonds over actively managed funds.
  • High-yield investments in tax-advantaged accounts: Keep income-generating assets like REITs and bonds in IRAs and 401(k)s.
  • Annual rebalancing: Adjust allocations strategically to maintain tax efficiency. Passive investors can also utilize tax-loss harvesting to offset capital gains and reduce taxable income without actively managing their portfolios.

Mezzi Wealth offers portfolio rebalancing with tax implications in mind, reducing unnecessary tax costs.

6. Consider alternative investments

Diversifying with alternative investments can provide tax benefits and reduce reliance on traditional stock markets.

  • Real Estate Investments: Rental properties generate depreciation deductions that offset taxable income.
  • Opportunity Zones: Investing in Qualified Opportunity Zones allows for deferral and potential elimination of capital gains tax.
  • Tax-Advantaged Annuities: Non-qualified annuities provide tax-deferred growth, delaying tax payments until withdrawals begin.

Mezzi Wealth evaluates alternative investment tax implications, helping you select the most efficient options.

7. Maximize other deductions

Beyond traditional retirement accounts and donations, high-income earners should leverage all available tax deductions.

  • Mortgage interest deductions: Limited to mortgages below $750,000, but still valuable for reducing taxable income.
  • Medical expense deductions: Deductible if medical costs exceed 7.5% of adjusted gross income.
  • Business deductions: High earners with side businesses or self-employment income can deduct expenses for home offices, equipment, and travel.

Mezzi Wealth automates deduction tracking, ensuring no tax-saving opportunity is overlooked.

Conclusion

High-income earners can significantly reduce their tax burden by implementing these strategic retirement tax-saving methods. Contributing to tax-advantaged accounts, leveraging Roth conversions, and optimizing investments all play a crucial role in minimizing tax liabilities. Charitable giving, alternative investments, and deductions further enhance tax efficiency.

Mezzi simplifies tax saving, helping investors make data-driven decisions without manual tax calculations. By integrating these strategies, you can secure long-term financial stability while keeping more of your hard-earned wealth for retirement.
