The SMSF LRBA Deadline: What Triggers Grandfathering, and Do You Still Have Time?

Updated 2 July 2026

If your fund is mid-purchase right now, you’ve probably already run the anxious arithmetic: can we possibly settle before the ban lands on 10 August? Almost everyone asking that question is measuring against the wrong date. And for most, that’s the relief, because the date they’re losing sleep over isn’t the one that decides anything. You don’t have to settle before 10 August. You have to know one thing about your contract.

The short answer: Grandfathering of an existing SMSF limited recourse borrowing arrangement (LRBA) turns on the contract exchange date — not the settlement date. An arrangement where the contract was entered into before the new rules commence is protected, even if settlement happens afterwards. And the deadline is now fixed: the ban commences 10 August 2026 — the 45th day after the Treasury Laws Amendment (Tax Reform No. 1) Act 2026 received Royal Assent on 26 June 2026. If you are mid-transaction, the single most important thing you can do is confirm your exchange date against that date. Precisely, not approximately.

This is the question with the shortest fuse, so let me be exact about the dates that matter and the one most people get wrong.

Key dates at a glance

Date	What it is
26 June 2026	Royal Assent — Treasury Laws Amendment (Tax Reform No. 1) Act 2026 (Act No. 49, 2026)
10 August 2026	Commencement of the LRBA change (Schedule 5) — the 45th day after Assent
Your contract exchange date	The date that decides whether your arrangement is grandfathered
Your settlement date	Does not decide grandfathering — can fall after 10 August 2026 and still be fine
Your finance approval date	Not the trigger either

Key takeaways

– The trigger is contract exchange, not settlement. An arrangement entered into before 10 August 2026 is protected even where settlement falls later. This is now confirmed in the Act itself, not just commentary. – Settlement date is the wrong cutoff, and it’s the error people panic over. A deal that exchanged in time but settles after commencement is still fine. – The deadline is fixed: 10 August 2026. No longer “around mid-August”. The Act’s commencement table sets it as the 45th day after the 26 June Royal Assent. – Finance approval is not the trigger either. Neither loan pre-approval nor formal approval determines grandfathering. The exchanged contract does. – Refinancing a pre-commencement LRBA is preserved — by the Act. The statute expressly carves out maintaining or refinancing a borrowing entered into before commencement (more below). – Mid-stream arrangements get transitional protection, but it’s dated and document-specific. Vague “I think we’re fine” is not a position; the exchange date on the contract is.

Why exchange, not settlement, is the date that counts

Grandfathering protects arrangements genuinely entered into before the law changed — and in property, you enter into the deal at exchange of contracts, when both parties are bound. Settlement, weeks or months later, is the completion of a commitment already made.

This is no longer a matter of interpretation. The Act’s own transitional provision (Schedule 5, item 2) puts it beyond doubt — the change does not apply where:

“the acquisition of the asset … happens under an arrangement entered into before that commencement (even if the settlement for the acquisition of the asset happens after that commencement).”

That distinction is costing people money in the forums right now. Trustees mid-purchase see “ban commences 10 August” and assume that if they can’t settle by then, the deal is dead. For most, that is the wrong fear. If contracts exchanged before commencement, the arrangement is grandfathered and can settle afterwards on its existing terms. The panic is real; the premise behind it usually isn’t.

The three dates people confuse — and which one actually governs

Three dates get blurred into one anxious question. Only one governs.

1. Finance approval date. Pre-approval and formal approval feel decisive because that’s where the stress lives. They are not the grandfathering trigger. A fund can hold approval and still be caught if contracts didn’t exchange in time; a fund can have exchanged and be protected while finance is still being finalised.

2. Settlement date. The completion date. It does not determine grandfathering. A protected arrangement can settle after 10 August 2026.

3. Contract exchange date. This is the one. Exchange before 10 August 2026, and the arrangement is grandfathered. The contract — and the date on it — is the document that decides your position.

So the practical instruction is narrow and clear: find your contract, find the exchange date, and compare it to 10 August 2026. Everything else is noise until that comparison is made.

What “commencement” actually means here

Commencement is not a round number someone picked, and it is no longer an estimate. The Act’s commencement table sets Schedule 5 — the LRBA change — to commence on the 45th day after Royal Assent. Royal Assent was 26 June 2026, which fixes commencement at 10 August 2026.

That precision matters for a decision this consequential. In the fortnight after the deal was announced, the date genuinely was uncertain, and careful commentary (this page included) said so. It isn’t uncertain now — it is set in the enacted Act. What remains worth confirming is your side of the equation: the exchange date on your specific contract, and whether your arrangement’s documents support a pre-commencement position.

Refinancing an existing LRBA — now settled

One question had advisers and lenders genuinely unsure for a fortnight: can you still refinance an existing residential LRBA after the change? Much of the early commentary hedged it, because the ATO hadn’t ruled. The Act answers it directly. The transitional provision says the change does not apply to an arrangement:

“for maintaining (or refinancing) a borrowing of money under another arrangement entered into before that commencement.”

So refinancing a pre-commencement residential LRBA stays within the borrowing exception — you are not forced to sit on your existing loan and rate for the life of the arrangement. (The preserved case is refinancing a borrowing entered into before commencement. A brand-new residential borrowing after 10 August 2026 is still caught.)

If you’re mid-transaction right now

Here is the sequence that actually protects a position, in order:

1. Locate the contract and confirm the exchange date. Not approval, not the settlement booking — exchange. 2. Compare it to 10 August 2026. If exchange predates commencement, you are in grandfathered territory. 3. Confirm the arrangement’s documents are consistent — the holding (bare) trust, the LRBA terms, and the security all need to line up with a pre-commencement arrangement. 4. Get the timing confirmed before you act on it. “Probably fine” is not a structure. The dates are decisive, and they reward precision.

A worked example, anonymised: a trustee mid-purchase nearly walked away from an in-train arrangement because they couldn’t settle before the change. On checking the contract, exchange had already occurred — the deal sat inside the grandfathering window and could complete on its existing terms. The value at risk was a viable position abandoned over the wrong date, not any breach.

The cost of acting on the wrong date

Two mistakes cost real money here, and they pull in opposite directions.

The first is giving up too early — abandoning a grandfathered arrangement because you measured against settlement instead of exchange. That surrenders a position the law would have protected.

The second is assuming you’re safe when you’re not — treating a deal as grandfathered when contracts hadn’t actually exchanged before 10 August 2026, or when the documents don’t support it. That risks the arrangement and, worse, the fund’s complying status.

Both errors come from the same root: deciding on a half-remembered date instead of the exchange date on the actual contract. When the fuse is this short, precision is the whole strategy.

Frequently asked questions

If the clock is running on your deal

This is the one page on the site with a real deadline behind it. Commencement is 10 August 2026 — weeks away, not months — and the date on your contract, not your loan, decides whether your arrangement is protected. Acting on a half-remembered date is the expensive mistake here, in both directions.

The clean next step is narrow: confirm your exchange date against 10 August 2026 before you assume either way. A structuring conversation does exactly that — you leave knowing whether you’re inside the window or not, and what that means for settlement. This isn’t about rushing a settlement. It’s about knowing which date governs before you decide anything.
