How to set up a discretionary trust, step by step

The trust type families actually use: the trustees decide who gets what, when. Every step, every form, every official link, and the honest tax bill at each stage.

The short answer

A discretionary trust holds assets for a group of people you name, and the trustees choose how to share income and capital among them.
You set it up with a trust deed, a small starting gift, trustees you trust completely, and a registration with the tax office.
The flexibility is the point. The tax is deliberately heavy, so it saves money only when used for a real family reason.

Typical setup cost

£1,500 to £3,000

Solicitor drafted deed, UK

UK registration

Trust Registration Service

Within 90 days of creating it

Tax going in

20% above £325,000

UK lifetime charge, per person

Do it in this order

1Decide what the trust is for: school fees and children, passing down property, or holding family business shares. The purpose decides everything else.
2Choose your beneficiaries, the group who can benefit. Usually children, grandchildren and their spouses, named as a class rather than one by one.
3Choose at least two trustees. They legally own the assets and must act for the beneficiaries, not themselves. Pick people who will outlast you and say no to you.
4Instruct a solicitor to draft the trust deed, the rulebook: powers of the trustees, who can benefit, and when the trust ends. Do not use a cheap template for real money.
5Settle a small starting amount, often just £10, to bring the trust into existence. Large assets go in later, planned around the tax charges.
6Register the trust. UK: the Trust Registration Service within 90 days. US: get an EIN from the IRS. Australia: apply for a trust TFN and ABN with the ATO.
7Open a bank account in the trust's name. All trust money flows through it, never through a trustee's personal account.
8Transfer the real assets in, with advice first. In the UK, gifts above the £325,000 nil rate band are charged at 20% on the way in.
9Every year: file the trust tax return, record every distribution decision in trustee minutes, and in the UK keep the registration up to date.

Only if you want the detail

Where the money saving actually is

Assets given away more than seven years before death usually escape UK inheritance tax. A discretionary trust can hold them for the children in the meantime, under your rules.

The running tax, honestly

Trusts are taxed hard on purpose. Know the numbers before you start.

Mistakes that cost real money

These are the ones solicitors get paid to fix afterwards.

What people get told, and what is true

A discretionary trust makes the money untouchable by the tax office.

It is registered, it files returns, and it pays some of the highest rates in the system. It buys control and protection, not invisibility.

You can buy a deed template cheaply. The expensive part is fixing a badly drafted trust ten years later, usually with lawyers and a tax bill attached.

Now do it on your numbers

Reading is the easy half. The saving comes from applying this to your income, your country and this tax year, with the deadline written down.

Where this comes from

General guidance, not personal advice. Anything involving a company, a trust or another country should be checked by a qualified accountant or tax adviser before you act.
