6 Critical Mistakes to Avoid When Estate Planning with Your 401(k) or IRA in Texas

Retirement accounts like 401(k)s and IRAs can represent a significant portion of a person’s wealth. In Texas, missteps in planning for these assets can result in tax penalties, lengthy court involvement, and even unintentional disinheritance. Unlike other assets, these accounts are governed by contractual rules—not your will. This makes estate planning for retirement accounts especially important and uniquely complex. Below, we cover the six most common and costly mistakes that Texas residents—and their estate attorneys—must avoid when handling 401(k) and IRA accounts.

1. Inconsistent Beneficiary Designations

One of the most frequent mistakes in retirement estate planning is failing to align the beneficiary designation forms with your will or trust. Many people update their wills but forget to revise the corresponding retirement account paperwork. For instance, a will might leave an IRA to a spouse, while the IRA’s beneficiary form names a child or friend. In such cases, the account provider must legally honor the beneficiary designation form—even if it contradicts the will.

Since these forms control the distribution of 401(k) and IRA funds, they override wills and trusts unless the forms themselves are invalid or legally challenged. The only reliable way to prevent this is to regularly review and update your beneficiary designations, especially after major life events like marriage, divorce, or the birth of a child.

2. Naming Inappropriate Beneficiaries

Another common error involves naming minors or individuals unable to manage funds as direct beneficiaries. While this may seem straightforward, minors cannot legally manage inherited retirement funds in Texas. As a result, the inheritance will require costly and time-consuming court-appointed guardianship.

Additionally, if a special needs beneficiary receives retirement funds directly, they may lose eligibility for government benefits. The better alternative is to name a guardian or a trust as the beneficiary to manage the funds responsibly and protect the minor’s or special needs individual’s future. These designations should also be revisited once a child reaches adulthood.

3. Uninformed Spousal Designations After Divorce or Remarriage

Many people fail to update their 401(k) and IRA beneficiary forms following a divorce or remarriage. In Texas, although divorce may automatically revoke a former spouse’s right to inherit, not all account custodians interpret this consistently. If an ex-spouse remains listed, that individual could still receive the account, especially if no new beneficiary is named.

In remarriage scenarios, a new spouse may become the default beneficiary—potentially disinheriting children or other intended recipients. To avoid these issues, consider using a split designation (e.g., 50% to spouse, 50% to children) or trust-based planning to ensure clarity. Each marriage, divorce, and major family change should trigger a review of all retirement account beneficiary forms.

4. Missing Out on Tax Savings Through Charitable Giving

Many Texans overlook the tax advantages of leaving retirement assets to charities. When individuals inherit retirement accounts, they typically pay income tax on distributions. However, qualified charitable organizations can receive retirement account distributions tax-free.

If charitable giving is part of your estate plan, designating a charity as a 401(k) or IRA beneficiary can maximize your legacy while minimizing taxes. This is especially useful for individuals with larger estates or those looking to reduce required minimum distributions (RMDs) during their lifetime through qualified charitable distributions. Coordination with a financial advisor and estate planning attorney can help optimize these gifts for maximum benefit.

5. Lack of Communication with Family and Executors

A surprising number of individuals never inform their loved ones or estate executors about their retirement accounts, their locations, or the identities of their beneficiaries. Without this information, families can face confusion, extended delays, or even lose track of important accounts altogether.

Failure to communicate this information can also lead to legal disputes among heirs who are unclear about the decedent’s intentions. You should maintain a written and regularly updated list of all retirement accounts, providers, account numbers, and designated beneficiaries. Share this information with your executor and trusted family members so they can act quickly and correctly when the time comes.

6. Neglecting Tax Withholding on IRA Distributions

Many beneficiaries underestimate the tax implications of IRA distributions. Improper or insufficient tax withholding can result in large tax bills and IRS penalties. This mistake is especially common with inherited IRAs where required minimum distributions (RMDs) must begin immediately, even if the beneficiary is unaware.

To prevent this, consult a tax advisor before any withdrawals are made. A professional can help you plan RMDs, calculate estimated taxes, and choose appropriate withholding levels. This reduces the risk of underpayment penalties and ensures smoother financial transitions for heirs.

FAQs

If my will and IRA beneficiary form name different people, who inherits the account?

The financial institution will follow the IRA beneficiary form. This form legally overrides your will.

Can I name my minor child as my IRA beneficiary?

Yes, but it’s not advisable. Use a trust or appoint a legal guardian to manage the funds until the child is of legal age.

Does naming a charity as my 401(k) or IRA beneficiary offer tax advantages?

Yes. Retirement account assets left to qualified charities pass tax-free and can reduce your taxable estate while supporting causes you care about.
