When Estate Plans Don't Include Tax Plans, All Bets Are Off: 2 Financial Advisers Explain Why

Estate plans aren't as effective as they can be if tax plans are considered separately. Here's what you stand to gain when the two strategies are aligned.

When most people think about estate planning, they picture documents: Wills, trusts, powers of attorney and beneficiary forms. While those documents are important, they're only part of the picture.

What gets overlooked is that nearly every estate planning decision also creates a tax outcome, sometimes immediately, sometimes years down the road.

In our experience, the most effective estate strategies are built alongside thoughtful tax decisions. When estate planning and tax planning operate in silos, families can unintentionally create higher tax bills for themselves or their heirs.

Estate planning isn't just about what happens after you're gone

Estate planning is frequently viewed as relevant only at the time of death. In reality, it's an ongoing process that affects income taxes, capital gains and retirement distributions throughout your lifetime.

Decisions about when to take income, how assets are titled and which accounts are drawn down first can influence not only your own tax situation, but also the tax burden your beneficiaries may inherit.

An estate plan that looks sound on paper can still produce unfavorable results if taxes aren't considered along the way.

That's why estate planning works best when it evolves alongside your financial life.

Retirement accounts can create hidden tax challenges for heirs

For many retirees, tax-deferred retirement accounts such as traditional IRAs and 401(k)s represent a significant portion of their net worth. These accounts are effective accumulation tools, but they can become tax complications when passed on to the next generation.

Under current rules, most non-spouse beneficiaries must withdraw funds from inherited retirement accounts within 10 years. Those withdrawals are generally taxed as ordinary income.

For adult children in their peak earning years, that income can be layered on top of salaries, bonuses and other compensation, potentially pushing them into higher tax brackets.

Without coordination, families may leave heirs with less flexibility and higher tax exposure than expected.

Beneficiary designations deserve regular review

One of the most common oversights we see involves beneficiary designations that haven't been reviewed in years. These forms often override instructions in wills and trusts, yet they're easy to forget once accounts are established.

Life changes such as marriages, divorces, births and deaths can all affect whether beneficiary choices still make sense. Beyond that, tax rules governing inherited assets have changed, making periodic reviews even more important.

Naming an individual, a spouse or a trust as beneficiary can lead to very different tax outcomes. Reviewing these designations regularly helps ensure they still align with family goals and tax considerations.

Roth strategies can reshape the tax picture of an estate

Roth accounts are often discussed in the context of retirement income, but their estate planning implications are just as significant. Because qualified Roth distributions are tax-free, they can offer heirs a very different experience than inheriting traditional retirement accounts.

Strategic Roth conversions may allow families to pay taxes at known rates today rather than leaving heirs to manage potentially higher tax burdens later.

While conversions are not appropriate in every situation, they can be a powerful tool when coordinated with both retirement and estate strategies.

The key is understanding that income decisions made during retirement can materially affect the after-tax value of an estate.

Gifting and charitable strategies can reduce lifetime and future taxes

Estate planning isn't limited to transfers at death. Lifetime gifting strategies can help manage future tax exposure, particularly when gifts remove appreciating assets from an estate.

Charitable strategies can also serve multiple purposes. Tools such as donor-advised funds may provide current-year tax benefits while supporting long-term philanthropic goals. When used thoughtfully, these strategies can improve tax efficiency without sacrificing flexibility or lifestyle.

The goal is not simply to reduce assets, but to transfer wealth in a way that reflects both personal priorities and tax realities.

Estate plans should adapt as tax laws evolve

Tax laws are never static, and estate plans shouldn't be either. While recent legislation has extended several key income tax provisions, future changes to estate and gift tax rules remain possible as lawmakers continue to grapple with long-term fiscal pressures.

Regular reviews help ensure that estate documents, beneficiary decisions and tax strategies remain aligned with current rules and realistic expectations about future change.

This becomes particularly important as retirement approaches, when required minimum distributions (RMDs), Social Security timing and health care costs begin to influence overall tax exposure.

The bottom line

Estate planning and tax planning are deeply connected. Decisions about income, investments, beneficiaries and gifting all shape how much of your wealth is ultimately preserved and how smoothly it transfers to the next generation.

When these conversations happen together, families are better positioned to reduce surprises and improve long-term outcomes. Estate planning isn't a one-time task. It's an ongoing strategy that benefits from thoughtful tax awareness at every stage.
