If you own stocks, ETFs, mutual funds, or brokerage accounts, then this stocks and living trusts guide is for you. Your investment portfolio should be an important part of your estate plan. Many San Diego families create a revocable living trust but forget to properly transfer investment accounts into the trust — potentially exposing loved ones to California probate and unnecessary tax issues later.
For investors, estate planning is about more than simply avoiding probate. Proper planning with stocks and living trusts can also help preserve wealth, simplify inheritance, protect beneficiaries, and maximize valuable tax benefits like the step-up in cost basis after death.
Whether you are a retiree, business owner, physician, or long-term investor, working with an experienced Carmel Valley trust attorney can help ensure your stocks and brokerage accounts are coordinated with your overall estate planning goals.
Why Investors Use Revocable Living Trusts
A revocable living trust is one of the most common estate planning tools used in California.
A properly drafted trust allows you to:
- Avoid California probate
- Maintain privacy
- Plan for incapacity
- Simplify inheritance process for your loved ones
- Coordinate investment assets
- Preserve potential tax advantages for your heirs
Many San Diego residents hold substantial wealth in:
- Brokerage accounts
- Individual stocks
- ETFs
- Mutual funds
- Tech company stock
- RSUs and investment portfolios
Without proper trust funding, these assets may still require probate even if a living trust exists.
Can Stocks Be Held in a Trust?
Yes. Stocks and brokerage accounts, other than your unvested stock options and sometimes private company stock, can usually be transferred into a revocable living trust.
This process is commonly called “trust funding.”
Instead of holding the account individually, ownership changes from:
John Smith
to
John Smith, Trustee of the Smith Family Trust dated January 1, 2026
You still maintain full control over the investments while alive.
You can continue to:
- Buy and sell stocks
- Manage investments
- Receive dividends
- Trade normally
- Change investment strategies
The trust simply becomes the legal owner of the account.
Why Putting Stocks in a Trust Matters
1. Avoid California Probate
California probate can be expensive and time-consuming.
If investment accounts remain outside the trust when someone dies, the family may still need probate court involvement before beneficiaries gain access.
For families with large investment accounts, probate fees can become substantial because California statutory probate fees are based on gross asset value.
A properly funded trust can allow a successor trustee to manage and distribute investments without court supervision.
This is one reason many families seek help from a San Diego estate planning attorney before retirement or after significant investment growth.
2. Simplify Incapacity Planning
If you become incapacitated, your successor trustee can step in to help manage brokerage accounts and investments without requiring a conservatorship proceeding.
For active investors or retirees who closely monitor portfolios, this flexibility can be extremely important.
3. Preserve Privacy
Unlike probate proceedings, revocable living trusts generally remain private.
Your stock holdings, beneficiaries, investment values, and inheritance instructions are not typically exposed in public court records.
The Step-Up in Cost Basis: A Major Tax Benefit for Investors
One of the biggest estate planning advantages for investors in the contexts of stocks and living trusts is the step-up in cost basis after death.
What Is Cost Basis?
Cost basis is generally the original purchase price of an investment.
For example:
- You buy stock for $25,000
- Years later it grows to $250,000
Your basis remains $25,000.
If you sold during your lifetime, you could owe capital gains taxes on the $225,000 gain.
What Happens After Death?
When appreciated stocks pass to heirs after death, the tax basis is often adjusted to the fair market value on the date of death.
This is called a step-up in basis.
Example
Imagine a San Diego investor purchased NVIDIA stock years ago for $15,000.
At death, the shares are worth $400,000.
If the beneficiaries inherit the stock:
- Their new basis may become $400,000
- If they immediately sell near that value, capital gains taxes could be minimal or eliminated
This can erase decades of built-in taxable gain.
For long-term investors, the savings can be significant.
Does a Revocable Living Trust Preserve the Step-Up in Basis?
Yes — with a few exceptions, the rule is that assets held in a revocable living trust receive a step-up in cost basis after death.
Many investors mistakenly believe transferring stocks into a trust eliminates tax advantages. Generally, that is not true for revocable living trusts.
California Community Property Rules Can Increase Tax Savings
California community property laws can create additional tax advantages for married couples.
In many situations, when one spouse dies, both halves of community property assets may receive a full step-up in basis.
This can apply to:
- Stocks
- Real estate
- Investment portfolios
Example
A married couple purchases stock for $100,000.
Years later, the account grows to $1 million.
At the first spouse’s death, the entire account may receive a new $1 million basis under California community property rules.
If the surviving spouse later sells near that value, capital gains taxes could be dramatically reduced.
This is one reason careful trust drafting is extremely important for married investors in California.
Common Estate Planning Mistakes Investors Make
Forgetting to Fund the Trust
Creating a trust alone is not enough.
If brokerage accounts are never retitled into the trust, probate may still be required.
Gifting Appreciated Stocks During Lifetime
Some parents gift stocks to children during life to “avoid taxes,” but this can unintentionally create large capital gains liability.
Example
- Parent buys stock for $20,000
- Stock grows to $300,000
- Parent gifts shares to child during life
The child usually inherits the parent’s original $20,000 basis.
If sold, the taxable gain could still be $280,000.
In many situations, inheriting appreciated stock after death provides a far better tax result because of the step-up in basis.
Failing to Coordinate Beneficiary Designations
Investment accounts, retirement accounts, and trusts should all work together as part of a coordinated estate plan.
Improper beneficiary designations can create unintended tax and inheritance consequences.
Should Retirement Accounts Go Into a Trust?
Usually no.
Accounts such as:
- IRAs
- 401(k)s
- Roth IRAs
- 403(b)s
are not retitled into a revocable living trust during a person’s life.
Instead, retirement account planning is generally handled through:
- Beneficiary designations
- Trust beneficiary planning
This area is highly technical and should be reviewed carefully with a qualified estate planning attorney.
Estate Planning for Investors in San Diego
For many California families, investment accounts eventually become one of the largest components of their estate.
A comprehensive estate plan should coordinate:
- Trust funding
- Brokerage account titling
- Tax planning
- Beneficiary designations
Working with an experienced Carmel Valley trust attorney can help ensure your trust and investment accounts are structured properly under California law.
Frequently Asked Questions
Can I still trade stocks if they are in my trust?
Yes. You maintain full control of investments as trustee of your revocable living trust during your lifetime.
Do stocks in a trust still receive a step-up in basis?
In most revocable living trust situations, yes. Appreciated stocks often receive a new basis equal to fair market value at death.
Do retirement accounts receive a step-up in basis?
No. Retirement accounts are governed by different tax rules.
Can a trust help avoid capital gains taxes?
A revocable trust itself does not eliminate capital gains taxes, but proper estate planning may help preserve valuable step-up in basis treatment for heirs.
What happens if brokerage accounts are not transferred into the trust?
Those accounts may still need to go through California probate depending on how they are titled, whether they have transfer on death beneficiary nominations, and the total value of the estate.
