Succession Planning and Tax: What to Get Right Before You Hand Over

Handing over a family business rarely costs you tax on the day it happens. The cost comes later. That's what tax governance really means for a family business: records good enough to answer questions you won't be around for.

That's the part worth getting right, and it comes down to what you write down at the time. The ATO refreshed its guidance on 21 August 2026, which makes it a good moment to work through what a plan actually needs: the records that matter, the events that should send you back to it, and the traps in each part of a handover.

‍

Quick overview

• Succession rarely triggers tax now. It creates positions someone defends later.
• Write the plan down, even a rough one. Revisit it whenever the family or the business changes.
• Keep records of four things: who owns what, assets moving in or out, entities opened or closed, and money moving between your own entities.
• Get valuations at the time, not years afterwards.
• For a big restructure or a sale, you can agree the tax treatment with the ATO before you go ahead.

‍

Two very different journeys

Succession goes one of two ways.

• Selling the business. You exit to an outside buyer and the proceeds fund your retirement.
• Handing it to family. The business keeps going, but ownership, income and control move to the next generation.

These aren't the same problem. A sale is one event. You've got a capital gains bill to work out, concessions to test, and a decision about timing.

A family handover is different. It's dozens of small steps spread over years, and each one can be picked up and looked at on its own long afterwards.

There's no single right approach. Your plan might involve restructuring, selling assets, retirement planning and estate planning all at once. That's exactly why the paperwork matters.

‍

The four things to keep records of

Any transaction with a tax effect, now or later, needs a paper trail. Four categories cause the most trouble, and they're the ones the ATO singles out.

1. Who owns what, and what that ownership actually gives them. Not just shares or units. The rights underneath them: who gets the income, who gets the capital, and who gets the vote. These three can move separately, and in family handovers they usually do. If your family member starts receiving income years before they get control, write down that sequence as it happens.

2. Assets moving in and out. Anything you buy, sell or transfer, and every restructure. Even the ones where you claimed rollover relief and no tax was payable at the time.

3. Entities you open and close. New trusts and companies, and the ones you quietly stop using. Closing is the one people forget, because it feels like tidying up rather than a transaction.

4. Money moving between your own entities. Loans, repayments, forgiven debts, guarantees. This is the one that causes the most grief. It's where Division 7A lives, the rules that stop company money leaving tax-free. A loan you forgave and never wrote down is very hard to explain a decade later.

Get a valuation wherever value matters, and get it at the time. Working out what something was worth ten years ago is an argument. Having the valuation from back then isn't.

What this looks like in practice

Here's how it usually plays out.

You built a family business and wrote a basic succession plan years ago. Since then the business has grown and your children have grown up. They work alongside you now, and you'd like them to take over when you retire. You sit down with your adviser to map out the handover. Your adviser explains the tax consequences and raises options you hadn't considered. You settle on restructuring into a family trust, so you keep some control while pulling back from the day to day.

Then comes the part most people skip. You update the succession plan to match what you actually decided, and you keep the documents showing what happened and why. Years later, when the transactions show up in someone's tax return, the reasoning is still there.

‍

A plan isn't something you write once

Review it regularly, and straight away when things change. Three triggers matter more than the rest.

• Family relationships change. Marriage, or a relationship breaking down.
• Life happens. Illness, or new family members.
• The business changes. Structure or operations.

The first one deserves attention. A plan written assuming a child's spouse stays in the picture, or a business partner stays well, can end up somewhere nobody intended. Family law and tax law don't move together. The plan that causes the dispute is usually the one nobody has looked at since it was written.

One more thing that's easy to miss. Think about the tax consequences for the people your plan affects, not just for yourself. A structure that suits you can hand your family a problem they didn't choose and can't easily undo.

The four parts of a succession plan

Succession splits into four areas, and each one carries its own traps. Here's what to watch in each.

Transferring your business to family members.
The mechanics of a handover: changing share structures, changing a trust's trustee, appointor or beneficiaries, changing partnerships, or moving assets into new trusts. Keep the asset records too, meaning when you bought it, what it cost, what you spent improving it, and any valuations. Two traps here. Transferring business assets usually has a capital gains bill attached, and selling a business can trigger GST as well. And if you hold a pre-CGT asset, one you've owned since before 20 September 1985, check whether it still counts as one. A change in who benefits from it can quietly cost you that status.

Exiting a business.
There are two ways out: selling, or closing down part or all of the structure. Closing is the one owners treat as admin. It isn't. Winding up entities without recording why and how is a gap that shows up years later, usually when someone else has to explain it.

Retirement planning.
For business owners this comes down to two things: the small business capital gains tax concessions when you sell business assets, and running your SMSF properly if it's part of the plan. Those concessions are worth real money and the rules are strict. Check whether you qualify long before you sell, not while you're selling.

Estate planning.
The meatiest of the four, covering wills, testamentary trusts and what an executor has to do. One point is worth repeating. Die without a valid will and your assets get distributed under your state's inheritance laws, so your intentions may not be followed. Because your beneficiaries pay different rates of tax, that can also leave some of them worse off than you'd have wanted. And be wary of arrangements dressed up as estate planning that are really just tax avoidance. If someone is selling you a structure mainly on its tax outcome, that's the warning.

‍

You can settle the tax treatment first

For big transactions, restructures and business sales included, you can go to the ATO before the deal happens through early engagement and pre-lodgment agreements. In plain terms, the tax treatment gets agreed up front instead of argued about afterwards.

Most private business owners don't know this is open to them, or assume it's only for big corporates. If your plan involves a serious restructure or a sale, it's worth asking. Certainty up front is a lot cheaper than a position you have to defend later.

‍

Where to start

If you've got no plan, the first version doesn't need to be fancy. It needs to exist, and it needs to be written down.

1. Pick a direction. Sell, hand it to family, or genuinely undecided. Undecided is a fair answer. Just write it down.
2. Map what you've actually got. Every entity, who controls it, who gets the income, who gets the capital.
3. Find the holes in your records across those four categories, especially old loans between entities.
4. Get valuations where value will matter, and get them now rather than later.
5. Put a review date in the calendar, and treat any family or business change as a reason to bring it forward.

Succession is a structuring problem before it's a tax problem

Most succession conversations start too late. A sale is already on the table, or someone's health has forced the issue. By then the structure is what it is and the options have narrowed.

Started early, it pulls together several pieces at once: the company and trust structures holding the business, the tax treatment of each step, the wills and estate arrangements behind them, your SMSF if it's part of the plan, and the retirement plan the money is meant to fund. If selling looks likely, our capital gains estimator is a reasonable place to start sizing it up.

Those pieces work best designed together rather than bolted on one at a time. Get in touch if you'd like us to look at your structure and what your plan would actually mean in tax terms.
