Key Takeaways
- A bypass trust places assets in a separate trust at the first spouse’s death, using that estate tax exemption while supporting the survivor.
- The trustee manages and invests the assets, paying income and sometimes principal for the surviving spouse’s health, support, or living expenses.
- When the second spouse dies, remaining assets pass to chosen beneficiaries and are generally not included in the survivor’s taxable estate.
- These trusts help preserve wealth, protect assets from creditors, and guide how inheritances are passed on, especially in blended families.
- They can be expensive and complex to maintain, and may limit flexibility if laws or family needs change.
How Do Bypass Trusts Work?
A bypass trust is designed to transfer wealth to the next generation while limiting estate taxes. It allows assets to pass outside the surviving spouse’s taxable estate while still providing for that spouse during their lifetime.
To achieve this goal, three primary roles are involved.
| Role | Description |
|---|---|
| Grantor (Settlor) | The person who creates the trust. |
| Trustee | A fiduciary, often a financial or legal professional, who manages the trust and its assets. |
| Beneficiary | The person or entity who receives income or principal from the trust. |
Here's an overview of how bypass trusts work:
Step 1: Establish of the Trust
A trust agreement outlines the terms, conditions, and duration of the trust. It explains how assets will be managed and distributed after the first spouse’s death, including provisions for the surviving spouse and final beneficiaries.
Step 2: Fund the Trust
After the first spouse dies, assets up to the federal estate tax exemption amount are transferred into the bypass trust. These assets are generally not subject to estate tax at the surviving spouse’s death.
Assets above the exemption amount may pass directly to the surviving spouse, often using the unlimited marital deduction to avoid estate taxes at that time.
Step 3: Management of the Trust
The trustee invests and manages the trust assets. Income may be distributed to the surviving spouse. The surviving spouse may access principal in certain situations, such as healthcare, maintenance, or support, depending on the trust terms.
Step 4: Distribute Remaining Assets
After the surviving spouse dies, the remaining trust assets pass to the named beneficiaries. Because the assets were not included in the surviving spouse’s estate, they are typically not subject to estate tax at that stage.
This structure allows both spouses’ estate tax exemptions to be used.
Step 5: Meet Legal and Tax Requirements
The trust may have filing and reporting obligations based on state law and tax rules. The trustee is responsible for meeting all legal and tax requirements throughout the life of the trust, including proper reporting of income and distributions.
Before creating a bypass trust, consult an estate planning attorney and a financial advisor to review the implications, costs, and potential benefits.
What Are the Types of Bypass Trusts?
Bypass trusts are used in estate planning to transfer wealth in a tax-efficient way while supporting surviving family members. There are several types, each designed for different goals.
Credit Shelter Trust (CST)
Also called a bypass trust, a credit shelter trust allows both spouses to use their federal estate tax exemptions. When the first spouse dies, assets up to the exemption limit are placed in the trust. The surviving spouse can benefit from the trust. The assets in the trust are not subject to estate taxes at the second spouse’s death.
Family Trust (or AB Trust)
A family trust, or AB trust, divides the estate into two parts when the first spouse dies:
- A Trust: Typically holds assets for the surviving spouse.
- B Trust: Holds assets intended to pass to heirs.
This structure can help maximize estate tax exemptions and preserve wealth for beneficiaries.
Generation-Skipping Trust (GST)
A generation-skipping trust transfers assets directly to grandchildren, bypassing the children’s generation. It is designed to reduce estate taxes across multiple generations. A GST can provide income or principal distributions to family members, based on the trust terms.
Each type of bypass trust serves a specific purpose and has features suited to different estate strategies. Federal estate tax laws can change and may vary by state, so review your options with a qualified professional.
Estate planning includes many types of trusts designed for different situations. Understanding your options can help you choose the structure that aligns with your goal.
What Are the Benefits of a Bypass Trust?
A bypass trust offers several benefits for married couples, including:
- Tax Minimization: Allows both spouses to use their individual estate tax exemptions, which can reduce or eliminate estate taxes after the second spouse’s death. Assets placed in the trust, including any growth, are generally protected from estate taxes at that time.
- Providing for Surviving Spouse: Can create a steady income for the surviving spouse to help support financial stability. Depending on the trust terms, the spouse may also access the principal for specific needs, such as healthcare or living expenses.
- Wealth Preservation: Helps protect trust assets from the creditors of the surviving spouse and heirs. Also allows the grantor to control how and when assets are distributed, which can help prevent irresponsible spending.
- Ensuring the Intended Inheritance: Helps confirm that assets pass to chosen beneficiaries, such as children from a prior marriage. It can also keep family assets, such as a business or property, within the family.
- Legal Protections: Depending on state law, trust assets may be protected from creditors of the surviving spouse or heirs. The trust also provides clear legal instructions for managing and distributing assets, which can reduce disputes.

What Are the Potential Drawbacks of a Bypass Trust?
Although a bypass trust can offer meaningful tax and asset protection benefits, there are also trade-offs to consider:
- Complexity and Cost: Creating a bypass trust requires legal guidance, which can be expensive. Ongoing management, tax filings, and possible legal updates add complexity and may increase costs.
- Limited Access to Capital: The surviving spouse may have limited access to the principal, depending on the trust terms. The rules set at creation can be rigid and may not adjust to changing needs.
- Potential for Conflicts: Disagreements can arise, especially in blended families where the interests of a surviving spouse and stepchildren differ. Conflicts over trustee decisions or distributions may lead to tension or legal action.
- Regulatory Changes: Updates to tax laws, including estate tax exemptions, can affect how well the trust works. Legal changes may require revisions to maintain compliance and tax efficiency.
- Investment Challenges: The trustee must follow the trust’s investment guidelines, which may limit flexibility. Managing risk and return while providing income and preserving principal can be difficult.
Careful structuring can help maximize the advantages of a bypass trust while limiting potential downsides. Before moving forward, it is wise to review your goals with an estate planning attorney and a financial professional to determine whether this approach fits your situation.
How Much Does a Bypass Trust Cost?
The cost to establish and maintain a bypass trust varies based on location, estate complexity, and professional fees. Below is a general overview of the common costs.
Setup Costs
- Legal Fees: An attorney drafts the trust agreement. Fees can range from a few thousand dollars to tens of thousands, depending on the complexity of the trust document and whether the attorney charges an hourly or flat fee.
- Filing Fees: Some jurisdictions charge fees to file trust documents with the appropriate agency.
Ongoing Costs
- Trustee Fees: Trustees charge either a flat annual fee or a percentage of trust assets. The amount depends on the trustee and the size and complexity of the trust.
- Investment Management Fees: If trust assets are professionally managed, fees may apply. These are often based on a percentage of assets under management or a flat fee.
- Administrative Costs: Ongoing expenses may include accounting, tax preparation, and recordkeeping.
- Taxes: Income generated by trust assets is generally subject to income tax. Taxes may be paid by the trust or the beneficiary, depending on how the trust is structured.
Additional Costs
- Auditing and Compliance Costs: Some trusts require audits or ongoing compliance reviews, depending on the terms and jurisdiction.
- Dissolution Costs: When the trust ends, fees may apply for distributing assets and formally closing the trust.
Because costs vary, request detailed estimates from attorneys, trustees, and other professionals before moving forward.
Is a Bypass Trust Right for You?
Whether a bypass trust makes sense depends on your estate size, family situation, and long-term goals.
When a Bypass Trust May Be Helpful
- Estate Tax Implications: If your estate exceeds the federal estate tax exemption, a bypass trust can help reduce estate taxes. It can shield assets and future appreciation from taxation.
- Blended Families: A bypass trust can provide for a surviving spouse while preserving assets for children from a prior marriage. It also allows you to control how and when assets are distributed.
- Asset Protection: Trust assets may be protected from creditors of heirs and, in some cases, a surviving spouse. This may also reduce exposure to legal claims.
- Wealth Transfer Goals: It can help pass down specific assets, such as a family business, according to your wishes.
- Charitable Giving: A bypass trust can include structured charitable contributions and potential tax advantages.
When a Bypass Trust May Be Less Appropriate
- Smaller Estates: If your estate is well below the federal exemption amount, the cost and complexity may outweigh the tax benefits.
- Desire for Simplicity: If you prefer direct transfers to heirs, a trust may add unnecessary complexity.
- Need for Flexibility: Trust terms can limit access and control over assets.
- Capital Gains Considerations: Assets inherited directly often receive a step-up in basis, which may reduce capital gains tax if sold.
- Retirement Income Needs: If you expect to use a large portion of your assets during retirement, placing them in a trust may restrict access.
A bypass trust is not right for everyone. Speak with an estate planning attorney and a financial advisor to review the costs, benefits, and long-term impact before making a decision.

Frequently Asked Questions
What happens to a bypass trust if the surviving spouse remarries?
If a surviving spouse remarries, the bypass trust assets are not directly affected. However, remarriage can influence estate planning decisions, including tax exemptions, beneficiary rights, trustee designations, and overall coordination of the estate plan. Reviewing the trust with an experienced attorney can help address these new considerations and protect the trust’s assets.
Can I revoke a bypass trust?
Whether you can revoke a bypass trust depends on its terms. Most are irrevocable and cannot be changed once created, though some may allow limited updates, such as changes to trustees or investments. Fully revoking an irrevocable bypass trust would eliminate its tax advantages, so careful planning is important before setting one up.
What is the difference between a bypass trust and a marital trust?
A bypass trust uses the deceased spouse’s estate tax exemption to shelter assets immediately, while a marital trust defers estate taxes until the surviving spouse dies. A marital trust gives the surviving spouse full access and control, whereas a bypass trust limits access and may include other heirs as beneficiaries. Both avoid probate, but they differ in tax treatment, control, and how assets are distributed after death.
What is the difference between a bypass trust and a survivor's trust?
A bypass trust is designed to reduce estate taxes by using available exemptions and placing limits on how assets are accessed and distributed, often continuing beyond the surviving spouse’s lifetime. A survivor’s trust focuses on managing assets for the surviving spouse, typically allows full access to the principal, and usually ends at the spouse’s death. While both provide asset management, only the bypass trust offers added estate tax planning benefits.
