The most tax-efficient ways to pass on money to your heirs come down to three tools: the step-up in basis on appreciated assets, Roth conversions that let heirs inherit tax-free, and lifetime gifting within annual limits. Each works differently, and the right mix depends on which accounts hold your money.
In the short above, Austin walks through why the type of account matters as much as the dollar amount. A taxable brokerage account, a traditional IRA, and a Roth IRA each pass to heirs under different tax rules, so a thoughtful plan treats them separately.
Why does the type of account matter so much?
How your heirs are taxed depends less on how much you leave and more on where that money sits. The same $500,000 can reach your family with very different tax bills, depending on the account it comes from.
A traditional IRA or 401(k) holds pre-tax dollars, so withdrawals are taxed as ordinary income to whoever inherits them. A taxable brokerage account holds money you have already paid tax on, and it carries its own treatment at death. A Roth account has been taxed once and generally passes free of income tax. Sorting your assets into these buckets is the first step in transferring wealth efficiently.
How does a step-up in basis work?
A step-up in basis resets the cost basis of an appreciated asset to its market value on the day the owner dies. Cost basis is what you originally paid. When that basis steps up, the capital gains that built up during your life can disappear for your heirs.
Suppose you bought stock decades ago for $50,000 and it is worth $300,000 when you pass away. Sold during your life, that $250,000 of growth would be taxed. Instead, your heir inherits it with a new basis of $300,000, so selling soon after leaves little or no capital gain to tax.
This is why holding highly appreciated investments in a taxable account, rather than selling late in life, can be a deliberate choice. The step-up applies only to assets passing at death, so it rewards patience. Deciding which assets to hold and which to spend is a core part of investment planning and retirement planning.
Can a Roth conversion help your heirs?
A Roth conversion moves money from a pre-tax account, such as a traditional IRA, into a Roth IRA. You pay income tax on the amount converted now, and in exchange the money grows tax-free and passes to heirs without an income tax bill.
This matters because of how inherited retirement accounts are taxed. Under current rules, most non-spouse heirs must empty an inherited IRA within ten years. With a traditional IRA, every withdrawal is taxable income for your heir, often during their peak earning years in a high bracket. With an inherited Roth, those withdrawals generally arrive tax-free.
The question is one of timing and tax rates. Converting makes the most sense when you can pay the tax at a lower rate than your heirs would face later. Situations that often favor conversions:
- Your income dips in early retirement, before Social Security or required distributions begin.
- Your heirs are high earners who would inherit during expensive tax years.
- You have cash outside the IRA to pay the conversion tax, so the full balance keeps growing.
- You expect your own tax rates to rise over time.
Because conversions add to your taxable income in the year you make them, the size and timing deserve real attention. This is where having a CPA on staff changes the conversation. Our firm coordinates the investment decision and the tax decision together, so a conversion that looks good on paper does not quietly raise your Medicare premiums or push you into a higher bracket.

How does lifetime gifting reduce estate taxes?
Lifetime gifting means transferring money to heirs while you are alive. Each year you can give up to the annual exclusion amount to any number of individuals without filing a gift tax return, and those gifts leave your estate for good.
The power is in the compounding. When you give an asset away, all of its future growth happens outside your estate. A gift made in your sixties has decades to grow in your child's or grandchild's hands rather than yours. Done consistently, annual gifting can shrink a taxable estate while letting you see your family benefit.
Here is how the three approaches compare at a glance:
| Method | When tax is paid | Best fit |
|---|---|---|
| Step-up in basis | Gains often erased at death | Appreciated taxable assets |
| Roth conversion | Income tax now | Heirs in higher brackets |
| Lifetime gifting | None within annual limits | Transferring growth early |
Gifting covers more than cash. Paying a grandchild's tuition or medical bills directly to the institution generally falls outside gift limits entirely. For larger transfers, the strategy connects closely with your estate planning, since trusts and titling shape how and when heirs receive what you leave.
Which approach is right for your family?
There is no single best answer, because these tools work together rather than competing. Many families use all three: holding appreciated assets for the step-up, converting part of a pre-tax IRA over several years, and gifting steadily along the way. The right balance depends on your account mix, your tax bracket, and your heirs' situations.
What ties them together is coordination. An investment move that ignores taxes, or a tax move that ignores your investments, can undo its own benefit. To map out how these strategies fit your situation, schedule a conversation with our team and we will review your accounts and goals together.

Frequently asked questions
What are the most tax-efficient ways to pass money to heirs?
Three common methods stand out: letting appreciated assets receive a step-up in basis at death, converting pre-tax retirement money to a Roth so heirs inherit tax-free, and gifting during your lifetime within annual exclusion limits. The best mix depends on your accounts and goals.
What is a step-up in basis?
A step-up in basis resets the cost basis of an inherited asset to its value on the owner's date of death. This can erase capital gains that built up during the owner's life, so heirs who sell soon after inheriting may owe little or no capital gains tax on that growth.
Do my heirs pay taxes on an inherited Roth IRA?
Qualified withdrawals from an inherited Roth IRA are generally income-tax-free, since the original owner already paid tax on the contributions and conversions. Most non-spouse heirs must empty the account within ten years, but the withdrawals themselves usually arrive without an income tax bill.
How does annual gifting reduce future taxes?
Each year you can give up to the annual exclusion amount to any number of people without filing a gift tax return. Gifting moves assets, and their future growth, out of your estate gradually. Over many years this can meaningfully reduce what your estate is worth at death.
