When many people think about taxes, it might be towards the end of the calendar year, when it comes to donating to charities or when you come across an article about tax-saving moves before the end of the year. And while donating to charities that you believe in is great, or an article reminding you to max out your 401(k) or consider a last-minute Roth conversion can all help reduce your taxes, they are short-term fixes. It usually works better to step back and look at your taxes over several years, not just one.

When you look at several years of tax returns together, you can start to build a customized approach. And that plan can be adjusted not only as your life changes but also when tax laws change. By reviewing multiple years at a time, one can often achieve results that are more thought out and less last minute.

So what exactly are some of the tools that can be used to achieve tax-efficient financial planning?

1. Choosing Which Accounts Hold Which Investments (a.k.a. Tax-Efficient Asset Allocation)

Where you keep your investments matters. Some accounts are better for certain investments than others if you want to keep more after-tax returns. For example, placing high-growth assets in Roth individual retirement accounts (IRAs) allows for tax-free growth, while holding income-generating assets in traditional IRAs or 401(k)s defers taxes until retirement when withdrawals may be taxed at a lower rate.

2. Tax-Loss Harvesting

Selling investments at a loss to offset capital gains from other investments can help reduce your taxable income. If you harvest losses during the year, you can trim down your tax bill and sometimes boost long-term returns.

3. Managing Required Minimum Distributions (RMDs)

RMDs from traditional retirement accounts now must start at age 73, and failing to take them can result in costly penalties. By planning your RMDs strategically, you can manage your taxable income. You might even convert some funds to a Roth IRA and avoid getting pushed into a higher bracket.

4. IRMAA and Medicare Premiums – Staggering Income and/or Distributions

Income-related monthly adjustment amounts (IRMAA) can increase Medicare premiums for high-income retirees. By carefully staggering income and distributions, you can avoid crossing IRMAA thresholds or at least time them strategically, thereby keeping your Medicare costs lower.

5. Roth Conversions When Income is Low

Converting traditional individual retirement account (IRA) funds to a Roth IRA during years when your income is low can be highly beneficial. One good time can be before age 73 when you must start claiming required minimum distributions (RMDs). This allows you to pay taxes on the converted amount at a lower rate, and future withdrawals from the Roth IRA will be tax-free.

6. Social Security Timing

Deciding when to start taking Social Security benefits can significantly impact your retirement income and tax situation. Delaying benefits increases your monthly payout, but careful planning is needed to balance this with other income sources and tax implications.

7. Health Savings Accounts (HSAs) – Triple Tax Incentive

HSAs offer a triple tax advantage: contributions are tax-deductible, earnings grow tax-free, and withdrawals for qualified medical expenses are tax-free. Maximizing HSA contributions can significantly enhance your tax efficiency and provide a valuable resource for healthcare costs in retirement.

8. Tax-Efficient Withdrawal Sequence

Withdrawing from retirement accounts in a tax-efficient sequence can minimize your overall tax burden. A common rule of thumb is to tap taxable accounts first, then tax-deferred, and save Roth money for last. This approach requires careful planning to account for required minimum distributions (RMDs), Social Security, and other income sources.

9. Charitable Giving Strategies

Qualified Charitable Distributions (QCDs) let individuals 70½ or older donate up to the annual IRS limit (over $100,000) directly from their individual retirement account (IRA) to a charity, counting towards required minimum distributions (RMDs) and reducing taxable income. Donor-advised funds (DAFs) provide an immediate tax deduction for contributions, and by bunching charitable contributions in high-income years, you can maximize your tax benefit. Both strategies offer tax benefits and flexibility in charitable giving.

10. Estate Planning – Still a Smart Strategy

With recent law changes (the passage of the One Big Beautiful Bill Act of 2025), the sunset provisions of the Tax Cuts and Jobs Act of 2017 are no longer a concern. The federal estate and gift tax exemptions have been permanently increased to $15 million per individual starting in 2026, with future adjustments for inflation.

However, many state estate and inheritance tax laws do not align with the higher federal exemption and can be significantly lower, sometimes as low as $1 million. This makes proactive estate planning essential. Strategies such as trusts and gifting, designed with both federal and state exemptions in mind, can help minimize estate taxes.

Final Thoughts:

These are just some of the tools that, when used as part of a comprehensive, multiyear tax-efficient financial planning strategy, can significantly enhance your tax efficiency and overall financial health. Unlike the once-a-year interaction with your accountant or online tax filing website, a financial planner should take a holistic view of your finances, adjusting strategies as your life and the tax laws evolve. Working with a planner keeps your tax strategy proactive instead of reactive and that usually means less stress and better long-term results..

So, while your accountant, whether a person or tax software, plays a crucial role in filing your taxes correctly, a financial planner should look at the bigger picture to help you save more and stress less. Over the coming weeks, a deeper dive into these topics will help you move beyond the year-end chat.
