Family Trust Vesting Date
Family trusts · Business owners
The family trust is one of the most common structures in Australian business, and buried in every deed is a date most owners have never read. In Western Australia, it's one you can't push past. Here's why it matters, and why timing is everything.
Trusts are everywhere in Australian business. The ATO's taxation statistics count more than a million of them, with 1,022,229 trust tax returns lodged for 2022-23 alone, and the discretionary (family) trust is the structure of choice for family enterprises right across WA. If you operate through one, your deed contains a vesting date: sometimes called the termination or perpetuity date. It's the day the trust's flexibility switches off. Most owners have never looked it up, couldn't tell you what it is, and assume it's decades away and easily moved. Often it's none of those things, and the consequences of letting it pass unnoticed can be expensive and permanent. It's one of the most overlooked issues in the whole trust structure, and one of the most fixable when it's caught early.
What the vesting date actually is
Up to the vesting date, your trustee has discretion: the power to decide, each year, who in the family receives income and capital. On the vesting date, that discretion ends automatically. From that moment the trustee simply holds the assets for whoever the deed names as the "takers on vesting", a fixed group, often a default list written decades ago. The trust doesn't necessarily wind up or disappear; what disappears is your ability to choose.
What changes the day it vests
The discretion ends
- The trustee can no longer choose who receives income or capital.
- It's locked to the "takers on vesting" in the deed, often a default list you didn't choose and may not want.
Tax on gains you haven't banked
- Depending on your deed, the takers can become absolutely entitled to the assets.
- That can trigger CGT event E5, a deemed sale at market value across the whole trust: business, property, shares.
The top-rate trap
- If no one is presently entitled to income after vesting, the trustee is taxed on it.
- And that's at the top marginal rate, not a beneficiary's lower rate.
No rewind
- Not knowing the date doesn't change the legal position, and carrying on as normal doesn't fix it.
- Once interests have vested, a court is unlikely to extend them.
The assumptions that catch people out
✕ "We'll just extend it later"
- Extending works, but only before the date, using a valid power in the deed.
- After the vesting date, that door is generally closed.
✕ "No one will notice"
- The ATO applies its vesting ruling (TR 2018/6) when it reviews a trust.
- A missed date surfaces in an audit, a sale or a succession, usually at the worst time.
The fix is simple, if you act in time
Amending the vesting date before the trust vests, using a valid power in the deed or with court approval, does not trigger CGT event E1 and does not create a new trust. The ATO confirms this directly. Done properly and in time, it's usually a straightforward, low-cost exercise.
The catches: it has to sit within WA's 80-year ceiling, the deed has to actually contain a valid power to amend, and the change needs checking for other traps such as resettlement, and beneficiary or duty issues. This is where the tax and the legal advice have to work together.
Every option you have exists before the date. After it, most of them are gone.
What to do now
- Find the date. Dig out the trust deed, the original and every variation, and locate the vesting or termination date. If you can't find it or can't read it, that alone is reason to have it reviewed.
- Check the "takers on vesting". See who the deed says inherits when the discretion ends. It's frequently a default group that no longer reflects your family or your intentions.
- Act early if it's approaching. If the date is within sight, or the deed is old and unclear, get it reviewed for a valid amendment power well ahead of the deadline, not on top of it.
- Build it into succession planning. The vesting date, the successor trustee and the eventual wind-up all belong in the same conversation as your estate and business succession.
