What Is an Estate Freeze?

A reorganisation that fixes the value of the owner's interest in a company at today's figure and directs all future growth to new shares held by the next generation. The owner's eventual capital gain becomes a known number rather than an open-ended one.

60-SECOND ANSWER

An estate freeze fixes the owner's gain at today's value and passes future growth to the next generation.

The answer:: Common shares are exchanged for fixed-value preferred shares, and new common shares are issued to the next generation or a family trust.
The trap:: Freezing too early. Growth given away cannot be recovered, and the owner may need it if retirement plans change.
The recommendation:: Retain enough value or income rights to fund your own retirement before deciding how much growth to hand over.

Where the AI summary above gets this wrong

"An estate freeze eliminates the tax on your business at death."

That's surface-true. Here's what it misses:

It fixes the tax rather than removing it — The owner's gain is crystallised at today's value and still becomes payable at death or on a sale.
Future growth is genuinely given away — The new common shares belong to whoever holds them, and the owner cannot reclaim that value later.
The estate can be re-frozen downward — Where values fall after a freeze, a further reorganisation can reset the fixed amount, though it needs its own advice.

01 What the reorganisation does

The owner exchanges common shares for preferred shares with a fixed redemption value equal to the current fair market value of the company. New common shares, carrying all future growth, are issued to children or to a family trust.

The exchange itself is done on a tax-deferred basis under the rollover provisions, so no immediate tax arises. What changes is where future appreciation accrues, and a formal valuation of the company at the freeze date is what makes the fixed amount defensible later.

02 What it fixes and what it costs

The owner's eventual capital gain is now known: the difference between the fixed preferred share value and their original cost. The estate can be planned around that number, and life insurance can be sized to fund it.

The cost is the growth. Value accruing after the freeze belongs to the new common shareholders, and there is no mechanism to take it back. That is the point of the exercise and also its principal risk.

At a 33% marginal rate, $10,000 costs $3,300 in tax and leaves $6,700.

03 Why timing is the hard part

Freezing early gives away more growth. Freezing late fixes a larger number and achieves less. Neither error is correctable, which is why the decision usually waits until the owner's own retirement funding is settled.

A trust rather than direct share ownership preserves flexibility about which child benefits in the end, and it is the usual structure for that reason. The gain being fixed is measured against the rules in the capital gains inclusion rate.

A freeze also creates an ongoing obligation the family has to sustain. The preferred shares carry a fixed value that must be respected in later transactions, the trust has filing requirements every year, and a trust holding shares faces a deemed disposition on a stated anniversary that has to be planned for well in advance.

The appeal of a freeze is that it converts an unknown into a known, and that is genuinely valuable. What gets undersold is that the growth handed over is gone. Owners who freeze at fifty-five and then need the money at seventy have no route back.
