Simple Trusts vs. Complex Trusts

A trust can be a useful tool in your estate planning, allowing you to remove assets from probate and potentially minimize estate and gift taxes. It helps ensure the management of trust assets on behalf of beneficiaries and in accordance with your wishes. 

There are different types of trusts you can establish, with some more specialized than others. This is especially evident when comparing simple vs. complex trusts. Knowing how these broad categories of trusts compare can help you choose the right option for your estate plan.

A financial advisor can help you create a trust and develop your estate plan.

What Is a Trust?

A trust is a type of legal entity created under your state’s laws to manage your assets. The person who creates a trust is a grantor, and they have the right to transfer assets into the trust.

They can also choose one or more trustees to oversee the trust. The trustee’s job is to manage assets in accordance with the grantor’s specifications on behalf of one or more trust beneficiaries.

For example, you might set up a trust to hold assets that you want distributed among your three children when you pass away. Another option is to choose your favorite charitable organization as the beneficiary of your trust.

There are many different types of trusts, each serving a different purpose: 

• Revocable trust. A grantor can change their revocable trust during their lifetime. If you have this type of trust and want to add assets to it or change the beneficiaries, you can do so while you’re still living. 
• Irrevocable trust. An irrevocable trust involves a permanent transfer of assets.
• Grantor trust. In a grantor trust, the trust creator retains certain powers over the trust, including rights to the trust’s assets and income. The trust creator may include trust assets in the estate when they pass away. 
• Non-grantor trust. With a non-grantor trust, the trust creator has no interest or control over trust assets. Trust assets are generally excluded from the trust creator’s estate at their death.

Benefits of Trusts in Estate Planning

Trusts can serve a number of functions with significant benefits for an estate plan. 

There are several benefits of creating a trust:

• Pass specific assets to your chosen beneficiaries
• Avoid probate for certain assets
• Manage estate tax
• Limit gift tax liability
• Protect assets from creditors
• Ensure the continued care of a special needs beneficiary
• Receive the proceeds of your life insurance policy

Some of these scenarios may call for a simple trust, while others may require a more specialized trust. However, when it comes to choosing between simple trusts vs. complex trusts, do not forget to account for the corresponding tax liability.

Simple Trust Explained

A simple trust is a type of non-grantor trust. 

To be classified as a simple trust, it must meet certain criteria from the IRS. 

• The trust must distribute earnings annually from its assets to beneficiaries.
• No principal distributions are made.
• There are no charitable distributions.

With this type of trust, trust income is taxable to the beneficiaries, even if they don’t withdraw income from the trust. The trust reports its income to the IRS annually and may deduct any amounts distributed to beneficiaries.

While the trust itself must pay capital gains tax on earnings, a simple trust is also permitted to take a $300 exemption. ¹

Understanding Complex Trusts

A complex trust also has certain criteria it must meet. 

In order for a trust to be complex, it must do one of the following each year:

• Refrain from distributing all of its income to trust beneficiaries
• Distribute some or all of the trust’s principal assets to beneficiaries
• Make distributions to charitable organizations

There are also other rules to keep in mind before choosing a complex trust. 

First, the trust cannot distribute any principal unless all income has been distributed for the year first. Ordinary income takes first place in the distribution line ahead of dividends, and the trust must distribute dividends before capital gains. 

Once the trust meets these conditions, it can distribute the principal. However, all distributions must be equitable to all trust beneficiaries receiving them.

Complex Trust Taxation

Any trust that doesn’t meet the guidelines for a simple trust is considered a complex trust. 

Complex trusts can take deductions when calculating taxable income for the year. This deduction equals the amount of any income the trust must distribute for the year. 

A complex trust qualifies for an annual $100 exemption.

Simple Trusts vs. Complex Trusts: Which Is Better?

When it comes to simple and complex trusts, one isn’t necessarily better than the other. The type of trust that ultimately works best for you depends on its purpose.

• Income. A simple trust is fairly straightforward in the distribution and taxation of assets and income. A complex trust, on the other hand, can offer greater flexibility in estate planning if you have a high net worth or multiple beneficiaries.
• Level of control. When comparing trust options, consider whether you want to retain control or simply hold an interest in the assets you transfer into it. If you choose a simple or complex trust, you’re choosing a non-grantor trust. This means you’ll no longer have an interest in the trust assets. 

Talking to an estate planning attorney or financial advisor can help you decide which type of trust may work best for your financial situation.

Tax Reporting and Administration Differences

Simple and complex trusts follow different reporting standards, which affect the cost and time required for administration. 

Reporting Requirements

Both trusts must file Form 1041 each year, but the reporting burden often diverges once distributions and income categories are involved.

Trustees of simple trusts typically deal with a narrower set of tax issues because the trust must distribute all income annually. Meanwhile, complex trusts involve more administrative steps because the trustee may need to track retained income, principal distributions and any charitable transfers. 

Each action can affect how much of the trust’s income is taxable to beneficiaries versus taxable to the trust itself. This requires careful accounting and may increase the need for professional tax support.

Investment Oversight

Investment oversight can also differ between the two. 

A simple trust often follows a more predictable investment strategy because all income must pass through annually. A complex trust, however, may require more active management if principal distributions are allowed or if the trustee must plan around large charitable gifts or multiple beneficiaries with differing needs.

Recordkeeping obligations tend to expand under a complex trust because the trustee must carefully document discretionary decisions. These notes show compliance with fiduciary duties and help prevent disputes among beneficiaries.

Simple trusts, by contrast, have fewer decision points, making documentation requirements more limited and easier to manage.

Example: Taxation Between Simple vs. Complex Trusts

Consider a trust holding investments that generate $50,000 in annual income. Comparing income tax under simple and complex trust rules highlights the practical differences between the two structures.

Simple trust rules follow a general process.

• The trust must distribute all $50,000 of income to its beneficiaries by the end of the year.
• The trust takes a distribution deduction equal to that full amount, reducing the trust’s taxable income to zero before applying its $300 exemption.
• The beneficiaries, in turn, report the full $50,000 as taxable income on their own returns, taxed at each individual’s personal tax rate.

Under complex trust rules, the trustee may retain a portion of that income rather than making a full distribution.

Suppose the trustee distributes $30,000 to beneficiaries and retains $20,000 within the trust. The trust takes a distribution deduction for the actual $30,000 distribution, and beneficiaries must pay that amount on their individual tax returns.

The remaining $20,000 retained in the trust is subject to the trust’s tax rate, which is typically much more compressed than individual tax brackets. This means the trust reaches the highest marginal rate at a much lower income threshold than an individual would.

This compression is one of the most important practical differences between the two structures. Trusts hit the top federal tax bracket at a relatively low income level compared to individuals. Therefore, with a complex trust, retaining income instead of making distributions can sometimes result in a higher overall tax bill, even when the same income is generated in both scenarios.

The decision of how much to retain versus distribute under a complex trust is not purely about taxes. A trustee may have legitimate reasons to withhold income, such as protecting a beneficiary from mismanaging a large distribution or complying with the grantor’s specific instructions.

However, the tax consequence is real and worth factoring into the trust’s annual administration.

Bottom Line

The main difference between simple trusts and complex trusts lies in the distribution of income and assets and their tax liability. When deciding between a simple and a complex trust, be sure to carefully consider the size of your estate, the nature of its assets and your wishes for their management. It’s critical that you understand applicable tax requirements before creating either type of trust so you can determine how the trust will best fit into your larger estate plan.

Tips for Estate Planning

• Estate planning can get complex quickly. There’s a lot to consider and it may make sense for you to speak to a financial advisor to make sure that you’ve thought through everything properly. SmartAsset’s free tool matches you with vetted financial advisors who serve your area, and you can have free introductory calls with your advisor matches to decide which one you feel is right for you. If you’re ready to find an advisor who can help you achieve your financial goals, begin now.
• While trusts can offer numerous benefits, creating one doesn’t necessarily mean you don’t also need a last will and testament. You can use a will to distribute assets that you don’t want to include in a trust. Or you could create a pour-over will to transfer assets into a trust.
