Inherited IRA Split Between Siblings in California: What Families Need to Know

Inherited IRA Split Between Siblings in California: What Families Need to Know

When a parent passes away and leaves an IRA to multiple children, it can bring both financial opportunity and emotional stress.

One of the most common questions families in California ask is:

“How does an inherited IRA get split between siblings — and how are we taxed?”

The rules are straightforward once you understand them. But timing and tax strategy can make a big difference — especially in a high-tax state like California.

Let’s walk through it clearly.

Step 1: The Beneficiary Form Controls Everything

An IRA does not follow a will.

It passes according to the beneficiary designation listed with the financial institution.

If the account names:

Two siblings at 50% each

Three siblings at 33% each

That’s how it gets divided — regardless of what the will says.

The beneficiary form is what matters.

Step 2: Each Sibling Should Open a Separate Inherited IRA

After the original owner passes away, the IRA should typically be split into separate inherited IRAs, one for each sibling.

This is important because:

• Each sibling controls their own withdrawals
• Each sibling controls their own investment decisions
• Each sibling is responsible for their own taxes
• There’s less potential for family conflict.

If the account is not split properly, withdrawal rules can become complicated.

The 10-Year Rule in California

Under current federal law, most non-spouse beneficiaries must withdraw the entire inherited IRA within 10 years.

Each sibling:

• Has their own 10-year timeline
• Can choose when to withdraw within that window
• Pays taxes individually on their distributions (if traditional IRA).

You do not all have to withdraw at the same time.

How Taxes Work in California

This is where many families are surprised.

If the inherited IRA is a traditional IRA, withdrawals are usually:

• Taxed federally
• Taxed by California as regular income.

California does not provide special tax treatment for inherited IRA distributions.

That means if one sibling withdraws $200,000 in a single year, that amount is added to their taxable income — and California income tax can be significant.

If the inherited IRA is a Roth IRA, qualified withdrawals are generally:

• Tax-free federally
• Not taxed by California.

But the 10-year rule still applies.

Example: Three Siblings in California

Let’s say a parent leaves a $900,000 traditional IRA to three children.

Each sibling receives $300,000.

Sibling A withdraws everything in one year → potentially large federal and California tax bill.

Sibling B spreads withdrawals over 10 years → possibly lower total tax impact.

Sibling C waits until later years when income is lower → may reduce taxes further.

Each sibling can make their own decision once accounts are properly split.

Common Mistakes California Families Make

Here are mistakes I see frequently:

Not splitting the account quickly

Waiting too long to understand the 10-year deadline

Withdrawing too much in high-income years

Assuming all siblings must move together

Ignoring California tax impact.

Because California has higher income tax rates than most states, withdrawal timing really matters.

What If One Sibling Wants Cash Immediately?

That’s very common.

Once the IRA is divided:

Each sibling controls their own inherited IRA.

There’s no requirement that distributions be equal in timing — only equal in percentage ownership.

This often reduces family tension.

Emotional Reality

When siblings inherit money from a parent, emotions can run high.

Sometimes there’s pressure to:

Keep investments the same

Move quickly

Avoid uncomfortable money conversations.

But clarity early prevents conflict later.

A simple review of the rules can bring peace of mind.
