Common estate planning mistakes include outdated beneficiaries, improperly funded trusts, overlooking inherited IRA taxes, and failing to plan for incapacity. These mistakes can result in unnecessary taxes, legal costs, and delays for your heirs. Greenbush Financial Group helps families coordinate estate planning with their investments, retirement accounts, and long-term financial goals.
Estate Planning Mistakes That Can Cost Your Family Money
You may have spent decades building your retirement savings, creating a will or trust, and making sure your family is financially secure. But a few overlooked estate planning details could still leave your loved ones facing unexpected taxes, legal expenses, or delays.
Even families with an estate plan in place can make mistakes that create costly problems for their beneficiaries.
Here are seven common estate planning mistakes worth reviewing before they become your family's problem.
1. Not Updating Beneficiaries
One of the biggest mistakes is assuming your will determines who receives all your assets.
Retirement accounts, life insurance policies, and certain investment accounts generally transfer directly to the beneficiaries listed on those accounts, regardless of what your will says.
Example: You have a $750,000 IRA that still lists your former spouse as the beneficiary. Even if your will leaves everything to your children, the IRA may still go to your former spouse, depending on applicable laws.
Planning Tip: Review beneficiaries on IRAs, 401(k)s, life insurance, and investment accounts, especially after marriage, divorce, or the death of a family member. Don't assume these designations were updated when you revised your will.
2. Assuming a Will Avoids Probate
A will provides instructions for distributing your assets, but it doesn't automatically prevent probate.
Probate is the legal process of administering an estate. Depending on your state and the complexity of your assets, it may involve attorney fees, court costs, and delays.
A revocable living trust can help certain assets avoid probate, but only if it's properly funded.
Example: You establish a trust but never transfer ownership of your $600,000 home into it. The property could still require probate after your death.
Planning Tip: If you have a trust, periodically verify that appropriate assets are titled correctly. Simply signing trust documents doesn't mean your assets have been transferred into the trust.
3. Ignoring Taxes on Inherited Retirement Accounts
Traditional IRAs and 401(k)s can create substantial income taxes for your beneficiaries.
Under current rules, many non-spouse beneficiaries must withdraw the entire inherited retirement account within 10 years. Annual required distributions may also apply.
Example: Your daughter inherits a $900,000 traditional IRA while earning $150,000 annually.
If she withdraws the entire inheritance in one year, it could push a significant amount of income into higher tax brackets, resulting in a much larger tax bill.
Spreading distributions across several years may reduce the overall tax burden, depending on her circumstances and the applicable withdrawal rules.
Planning Opportunity: Roth conversions during retirement may help reduce future income taxes for beneficiaries, depending on your tax bracket and your heirs' expected income. The important question is whether paying some taxes during your lifetime could reduce the total taxes paid by your family.
4. Adding Children to Your Home's Deed
Some parents add their children to their home's deed to simplify inheritance.
However, doing so can create unintended tax and legal consequences.
Example: You purchased your home for $200,000, and it's now worth $650,000.
If you gift the house to your children during your lifetime, they generally receive your existing tax basis. If they inherit it after your death, the tax basis is generally adjusted to its fair market value at death.
That difference could potentially save substantial capital gains taxes when the property is sold.
Adding children as owners may also expose the property to certain creditor or divorce-related risks.
Planning Tip: Before changing property ownership, evaluate alternatives such as trusts or transfer-on-death arrangements where permitted. A decision intended to simplify inheritance could unintentionally create additional complications.
5. Not Planning for Incapacity
Estate planning should also address what happens if you become unable to manage your financial affairs.
Imagine your spouse experiences a serious medical event and can no longer handle financial decisions. Without the appropriate legal documents, you could face court involvement just to manage important financial or healthcare matters.
Important documents often include:
Durable financial power of attorney
Healthcare power of attorney
Advance healthcare directive
HIPAA authorization
These documents allow designated individuals to assist with important decisions when you cannot act independently.
Planning Tip: Make sure these documents are current and that the people you've selected understand their responsibilities.
6. Overlooking Estate and Inheritance Taxes
The federal estate tax exemption is $15 million per person in 2026, meaning most families will not owe federal estate taxes.
However, some states have separate estate or inheritance taxes with lower thresholds.
Income taxes on inherited retirement accounts and capital gains taxes can also affect how much your beneficiaries ultimately receive.
For married couples with substantial assets, estate tax portability and planning for the surviving spouse may also be important considerations.
Key Insight: Even if your estate is well below the federal estate tax exemption, your family could still face significant taxes. Coordinating inherited retirement accounts, investments, and property can be just as important as traditional estate tax planning.
7. Failing to Update or Communicate Your Estate Plan
An estate plan created 15 years ago may no longer reflect your wishes.
Marriage, divorce, grandchildren, retirement, changes in assets, or moving to another state can all create reasons to update your documents.
Your executor, trustee, and financial power of attorney should also know their responsibilities and where important documents are located.
You don't have to share every financial detail with your family, but leaving clear instructions can prevent confusion and disagreements later.
Planning Tip: Consider reviewing your estate plan every three to five years, or sooner after a major life event.
How to Protect Your Family From Costly Estate Planning Mistakes
An effective estate plan coordinates three important areas:
Legal documents: Wills, trusts, and powers of attorney should reflect your current wishes.
Financial accounts: Account ownership and beneficiary designations should match your estate planning objectives.
Tax planning: Retirement accounts, investments, and property should be evaluated for their potential tax consequences when inherited.
For retirees, this coordination is particularly important because decisions about Roth conversions, IRA withdrawals, and investment accounts during your lifetime can affect the taxes your heirs eventually pay.
Five Questions Worth Asking
Before your next estate planning review, consider:
Are my beneficiary designations current?
Are the appropriate assets properly titled in my trust?
Could my heirs face unnecessary taxes on inherited retirement accounts?
Do my spouse and family have the documents needed if I become incapacitated?
Do my estate documents and financial accounts work together as intended?

Frequently Asked Questions
-
What is the biggest estate planning mistake?
Failing to update beneficiary designations is one of the most common mistakes. Outdated beneficiaries can cause significant assets to pass to someone other than the person you intended. -
Do I need a trust if I have a will?
Not necessarily. A trust may help avoid probate and provide greater control over asset distributions, but the need depends on your assets, state laws, and family circumstances. -
Do beneficiaries pay taxes on inherited IRAs?
Distributions from inherited traditional IRAs are generally taxable income. Qualified inherited Roth IRA distributions are generally tax-free, although withdrawal deadlines may apply. -
How often should I update my estate plan?
Consider reviewing your estate plan every three to five years and after significant life events such as marriage, divorce, retirement, or a death in the family. -
Can I leave my house to my children without probate?
Potentially. Depending on state law, a properly funded living trust, transfer-on-death deed, or other ownership arrangement may allow a home to transfer without probate.
