Key Takeaways
- An A-B trust is an estate planning tool that helps married couples minimize federal estate taxes by dividing a joint trust into two separate trusts upon the death of the first spouse.
- Trust A, or the Survivor's Trust, remains revocable and under the control of the surviving spouse, while Trust B, or the Bypass Trust, becomes irrevocable and protects the deceased spouse's assets from estate taxes.
- This trust structure allows couples to utilize both spouses' federal estate tax exemptions, potentially enabling estates to pass to beneficiaries free of federal estate taxes.
- A-B trusts also provide asset protection from creditors and can be beneficial for blended families, ensuring that assets are distributed according to the couple's wishes.
What is A-B Trust?
An A-B trust, also known as a bypass trust or credit shelter trust, is an estate planning strategy designed to minimize federal estate taxes for married couples. This type of trust splits a joint trust into two separate trusts upon the death of the first spouse, allowing for strategic management of assets and tax benefits.
The A-B trust is initially created as a revocable living trust while both spouses are alive. Once one spouse passes away, the trust automatically divides into two irrevocable trusts: Trust A and Trust B. Trust A, also referred to as the Survivor's Trust, is managed by the surviving spouse, while Trust B, known as the Bypass Trust, holds the deceased spouse's assets.
- Trust A (Survivor's Trust): Remains under the control of the surviving spouse.
- Trust B (Bypass Trust): Holds the deceased spouse's share and cannot be altered.
Key Characteristics
A-B trusts possess several defining characteristics that make them a popular choice in estate planning. Understanding these key features can help you determine if this trust structure is right for your situation.
- Revocable and Irrevocable Components: Initially a revocable trust, it separates into one revocable and one irrevocable trust upon the death of a spouse.
- Tax Efficiency: The structure allows for both spouses' federal estate tax exemptions to be utilized effectively.
- Asset Control: The surviving spouse retains control over Trust A, while Trust B is managed according to the deceased spouse's wishes.
How It Works
Upon the death of the first spouse, the A-B trust automatically divides into Trust A and Trust B. Trust A contains the assets that are accessible to the surviving spouse, allowing them to manage and utilize these funds as needed. In contrast, Trust B is irrevocable and holds assets up to the federal estate tax exemption limit.
For example, if a married couple has a total estate of $20 million and the federal estate tax exemption is $13.99 million, upon the death of the first spouse, $13.99 million would transfer into Trust B. The remaining amount would remain in Trust A for the surviving spouse's management.
This structure not only helps in tax savings but also preserves the wealth for future generations. For further investment options, you might explore best bond ETFs for managing trust assets.
Examples and Use Cases
A-B trusts can be beneficial in various scenarios, particularly for couples with substantial assets or those with children from previous marriages. Here are some practical examples:
- A couple with a combined estate of $30 million creates an A-B trust. After the death of one spouse, $5.3 million goes into Trust B, while the rest remains in Trust A.
- In a blended family scenario, the deceased spouse can ensure that their children receive their intended inheritance through Trust B, thus protecting assets from being redirected to a new spouse.
- A couple can utilize an A-B trust to minimize estate taxes while ensuring that the surviving spouse has access to necessary funds for living expenses.
Important Considerations
While A-B trusts offer significant benefits, there are important considerations to keep in mind. The effectiveness of A-B trusts may fluctuate with changes in tax laws, particularly for estates that fall below the combined federal exemption limit.
For estates smaller than this limit, an A-B trust may not yield tax savings; however, it can still be advantageous for asset protection and control over beneficiary distribution. Additionally, Trust B requires a separate federal tax identification number, which may add to administrative complexity.
Overall, A-B trusts can be a valuable tool in estate planning, helping you navigate not only tax implications but also the distribution of assets according to your wishes.

Frequently Asked Questions
An A-B trust, also known as a bypass trust or credit shelter trust, is an estate planning tool that helps married couples reduce federal estate taxes. It splits a joint trust into two separate trusts upon the death of the first spouse.
An A-B trust is initially created as a revocable living trust. When one spouse dies, the trust divides into two parts: Trust A for the surviving spouse, which remains revocable, and Trust B, an irrevocable trust that holds the deceased spouse's share of assets up to the federal estate tax exemption.
The main tax benefit of an A-B trust is that it allows both spouses' federal estate tax exemptions to be utilized, potentially doubling the amount that can be passed to beneficiaries free of taxes. Trust B assets are excluded from the surviving spouse's taxable estate, protecting them from future estate taxes.
Trust A holds the surviving spouse's assets and remains under their control, allowing them to manage or amend it as needed. Trust B, however, is irrevocable and contains the deceased spouse's assets, providing income to the surviving spouse while protecting the principal from estate taxes.
The surviving spouse can receive income from Trust B assets but cannot access or change the principal except for specific needs such as health, education, maintenance, and support. This restriction helps preserve the trust's assets for future beneficiaries.
Beyond tax benefits, A-B trusts provide asset protection from creditors and legal claims against the surviving spouse. This protection remains even if the surviving spouse remarries, making it especially beneficial for blended families.
An A-B trust is typically funded during the couple's lifetime. Upon the death of one spouse, assets are allocated between Trust A and Trust B based on the federal estate tax exemption limits, ensuring optimal tax efficiency.
