The Estate Tax Freeze: Why Your US Brokerage Account Gets Locked After Death

If you own US stocks or ETFs through a broker like Interactive Brokers, here’s what nobody explains until it’s too late: when you die, that account doesn’t simply pass to your heirs. It gets locked. No trading, no withdrawals, nothing, until the broker receives clearance from the IRS.

This is often called the estate tax freeze. It’s not your broker being difficult. It’s your broker protecting itself, and it affects many Israelis and Americans living in Israel who hold US investments.

What is the estate tax freeze?

The estate tax freeze is the period after an account holder’s death when a US broker refuses to release assets until the IRS issues a transfer certificate (often called a Form 5173 transfer certificate). Until then, heirs can’t access, sell, or move the investments, even if no estate tax is owed.

Why do brokers freeze accounts after death?

Here’s the mechanic most people miss. The moment someone dies, US tax law places an automatic lien on their entire estate. There’s no assessment and no notice; it simply attaches (IRC §6324).

Whoever holds the property afterward, whether a broker, a bank, or an heir, can be held personally liable for unpaid estate tax, up to the value of what they hold. The regulation says this applies to anyone in “actual or constructive possession” of the property (26 CFR §301.6324-1(a)(1)).

Now put yourself in the broker’s seat. If it releases your account to your heirs and estate tax later turns out to be owed, the IRS can come after the broker. So brokers follow a separate regulation that tells them exactly how to protect themselves: obtain a transfer certificate from the IRS first (26 CFR §20.6325-1). That certificate is the IRS confirming the tax has been paid or isn’t owed, and that the assets can be released.

In one sentence: the broker holds your assets until it’s legally safe, not because the IRS ordered a freeze, but because the transfer certificate is the only way it knows it’s protected.

Who is affected by the estate tax freeze?

It depends on citizenship.

Non-US citizens living outside the US (including Israelis)

The threshold is brutal: just $60,000 in US-situated assets, such as US stocks and ETFs. Above that, an estate tax return (Form 706-NA) is required before the transfer certificate can be issued. And because the US has no estate tax treaty with Israel, Israeli residents don’t get treaty relief that investors in some other countries receive.

The IRS states that processing can take 12 to 18 months once it has all the necessary documentation.

US citizens living abroad (including Americans in Israel)

The tax picture is very different. US citizens receive the full federal estate tax exemption (about $15 million for deaths in 2026), so very few actually owe anything.

But the freeze can still happen. Brokers often still want IRS sign-off before releasing the account, even when no tax is due. Citizenship changes whether you owe the tax. It doesn’t automatically spare your heirs the paperwork.

Can a broker promise not to freeze your account?

No broker, Israeli, American, or otherwise, can reliably promise to skip this. It isn’t their call. It’s built into federal tax law and the liability rules that come with it. If a platform tells you it won’t freeze your account, ask where that’s written down, because the regulations point the other way.
