So did the 2026-27 Federal Budget just gut the scheme that underpins your SDA investment? The headline says $37.8 billion in NDIS cuts. The NDIA's own data says SDA is tracking almost exactly to forecast. Both are true, and the gap between them is the whole story.
The short answer
Yes, the budget cut $37.8 billion from the NDIS over four years, but the cuts land on running costs (plan management, support coordination, participation budgets, fraud control), not the housing. SDA was not in the cuts: pricing carries on through the existing 2023 to 2028 SDA Pricing Arrangements cycle. The number that matters most: the NDIA forecast roughly 25,985 SDA participants by March 2026 and the actual figure came in at 25,633, so SDA is doing exactly what was expected of it. Federal SDA funding is still projected to roughly triple by 2033 on pre-budget sector analysis. And the property tax changes lean SDA's way, with two catches: a knockdown-rebuild does not count as a new build, and most SDA is positively geared anyway, so the negative gearing change barely touches it.
Investor Briefing · 2026-27 Federal Budget
The NDIS budget 2026 SDA verdict, in plain English. The Budget delivered the biggest NDIS shake-up since the scheme began, yet the NDIA's own data says SDA is tracking almost exactly to forecast. Both are true, and the gap between them is the whole story.
That is the short version. The rest of this article shows the working: what the budget actually said, why SDA sits outside the changes, where the tax shift helps and where it does not, and the two catches that matter for some SDA projects more than others.
The cuts target the running costs, not the housing
According to budget.gov.au, the NDIS reforms in the 2026-27 Budget are forecast to save $37.8 billion over four years. The Government has been clear the scheme keeps growing every year and stays Australia's largest social program outside the Age Pension. So this is slowed growth, not a wind-down. The reforms split into four areas, and not one of them touches SDA pricing or who qualifies for SDA.
Plan management and support coordination move to a commissioned model. Participants will choose from a government-procured panel rather than the open market, and consultation is coming on how home and living supports get commissioned for Supported Independent Living (SIL) participants. All of this changes how the support services get bought. None of it changes how the housing gets funded. SDA is funded separately and is not part of it.
Access shifts to functional capacity, which sharpens the SDA case. Access to the NDIS moves from a diagnosis-based test to a standardised assessment of functional capacity, and the expectation is that this tightens access at the milder end of the participant pool. SDA is defined by the NDIS Agency as housing for people with extreme functional impairment or very high support needs, which is the far end of that pool, not the milder end. A tighter functional test makes genuine SDA-eligible participants easier to identify, not harder.
Social and community participation budgets fall 30%. Budgets for social, civic and community participation supports are being cut by 30%, with reductions starting as early as 1 October 2026. A new $200 million Inclusive Communities Fund partly offsets that by funding group-based activities outside individual plans, and a new planning framework rolls out from 1 April 2027 to make plans more consistent. These are operational supports. None of them include accommodation, and SDA payments to property owners are untouched.
Fraud and oversight controls get funded. The Government is putting real money into fraud detection and provider oversight. For a legitimate, well-run SDA asset, that is quietly good news. It lifts the floor under the worst of the provider market and clears out some of the noise that has hung around the scheme.
Key fact
The $37.8 billion in NDIS savings (source: budget.gov.au, Care and Opportunity overview, 12 May 2026) comes entirely from operational supports. SDA is not named in any of the four reform pillars. Its protection comes from existing structural separation, the SDA Pricing Arrangements, not from anything the budget added.
Why SDA sits outside the cuts
Six reasons SDA sits well clear of where the savings are coming from. The first is the one most market commentary skips straight past.
The NDIA's own forecast already called this. Here is where the headline reading falls down. Everyone quotes the $37.8 billion and assumes the whole scheme, SDA included, is being reined in because costs ran away. So look at the one number that tests that assumption: did SDA actually run away?
In June 2023 the NDIA published its SDA Demand Projections. It forecast SDA participants growing from 22,873 in June 2022 to 27,022 by June 2027. Read off that curve and the implied figure for March 2026 is about 25,985 participants.
The actual figure at March 2026 was 25,633, in line with the latest quarterly data.
If it were the runaway cost the budget set out to tame, the numbers would be sprinting past forecast. They are sitting right on it. The whole NDIS budget 2026 SDA story turns on this point: the cost pressure the government is chasing lives elsewhere in the scheme, which is exactly where the four reform pillars point.
SDA is capital funding, and the budget reformed operating costs. What the budget went after is recurrent operating spend. SDA is the capital piece, the bricks and mortar of accommodation supports. The Government contracts to pay an annual amount, indexed each year, against a 20-year notional asset life, and that sits inside the SDA Pricing Arrangements, a separate document from anything the budget reformed. National Disability Services has confirmed publicly that the delivery of SDA and the delivery of SIL are separate under the NDIS.
The Pricing Review treats SDA as a saving, not a cost. The 2022-23 SDA Pricing Review, still the foundation document for SDA pricing, concluded that SDA should be treated as an investment in scheme sustainability rather than just spending. It modelled what happens if SDA prices are not maintained: about 20,131 participants miss out on the SDA they need within ten years, and that cost simply moves somewhere more expensive, hospitals, aged care, the broader housing system. The budget left that framework alone. SDA pricing runs through the 2023 to 2028 cycle as planned.
SDA participants are the cohort the budget set out to protect. Only about 6% of NDIS participants have SDA in their plans. The stated goal across the whole budget was to restore the scheme's "original intent", support for people with high and complex needs. That is the SDA cohort, almost by definition. The reforms protect support for these participants while tightening access at the milder end, and SDA participants are explicitly not in the firing line for tighter access.
Federal SDA funding is set to grow. In FY25 the federal government put about $600 million into SDA, roughly 1.2% of total NDIS spend. Pre-budget sector analysis by MA Financial, drawing on EY modelling, has that allocation roughly tripling by 2033, with more than $14 billion in capital still needed to deliver around 5,000 new dwellings by then. The 2026-27 Budget did not revise those numbers.
SDA income stays government-supported and indexed. Your SDA income comes through the NDIS at prices set in the SDA Pricing Arrangements, indexed each year. The reasonable rent contribution your participants pay, 25% of the Disability Support Pension plus Commonwealth Rent Assistance, is itself indexed, because both base payments are. So both halves of the rental income stay government-supported and CPI-linked, and neither falls inside the operational reforms.
The property tax changes lean SDA's way, with two catches
The same budget reworked how investment property is taxed in Australia. These changes apply to every property investor, not just SDA owners. They happen to land in a useful spot for SDA, though the detail matters more than the headline.
Capital gains tax moves to an indexation model. From 1 July 2027, the 50% CGT discount is replaced by an inflation-indexed cost base plus a minimum 30% tax rate on the real gain. Only gains after 1 July 2027 are affected. If you already own a property at that date, the calculation splits: gains up to 1 July 2027 keep the 50% discount, and gains from that date on fall under the new indexation regime. The official framing from budget.gov.au is that investors pay tax only on their real capital gain.
Worth being straight about this: the Treasury worked example shows the new regime landing marginally above or below the old 50% discount depending on inflation over the hold. For SDA, a long-hold asset with CPI-linked income, the indexation model fits the cash-flow profile well. Well-matched is not the same as automatically better, though. The actual outcome turns on inflation, hold period, your marginal rate, and whether you take the new-build choice, which is the next part.
New builds get to choose their tax treatment, but a knockdown-rebuild is not a new build. This is the single most important detail in the tax package for SDA owners. The Government has written in that investors in new builds can choose between the old 50% CGT discount and the new indexation regime, whichever comes out better. Negative gearing against other income also stays available on new builds. That sounds great, and it largely is. Two catches decide whether your project actually gets it.
Catch one: a new build has to add supply. Buy an old house, knock it down, put up a brand new SDA dwelling on the same block, and that does not count as a new build under the budget definition. The whole point of the carve-out is to grow the total housing stock. A knockdown-rebuild leaves the dwelling count where it started, so it does not trigger the carve-out. This will catch a fair share of SDA projects, infill sites in established suburbs especially. Whether your project adds a net new dwelling is now a tax question, not just a planning one.
Catch two: most SDA is positively geared, so the negative gearing change barely lands. Standard residential property is usually negatively geared. SDA pays you to own it. With government-supported, CPI-linked income, most SDA dwellings run positive cash flow from year one, so there is no loss to deduct in the first place. The negative gearing change is real news for owners of standard rental property. For SDA owners it mostly solves a problem you never had. The CGT change is the part to watch.
The Treasury fact sheet lists a few more exemptions worth knowing: build-to-rent developments, properties in widely-held trusts and superannuation funds, and private investors supporting Government housing programs. That last one is an interesting category to sit near, given what SDA actually is.
Established residential property comes off worse. From 1 July 2027, negative gearing is limited to new builds. Buy established housing after budget night and your losses only offset property income, not your wages. That widens the gap between new-build SDA and established residential stock, and it widens it in SDA's favour.
Key fact
A new-build SDA dwelling that adds net new supply keeps the existing 50% CGT discount and existing negative gearing rules, and can also elect the new inflation-indexed CGT regime if it produces a better result (source: budget.gov.au, Tax Reform overview, 12 May 2026). A knockdown-rebuild does not qualify.
NDIS budget 2026 SDA versus a standard rental, side by side
Put new-build SDA next to a standard established rental under the new rules and the gap is easy to see. The two get treated quite differently.
A standard established rental bought after budget night takes the changes full in the face. From 1 July 2027 its losses only offset property income, not wages, and on sale it falls under the new indexation model with the 30% minimum, no option to keep the old 50% discount. On top of that, its return leans heavily on market capital growth, which is cyclical and entirely outside your control.
SDA plays a different game. As a new-build asset, provided the project adds a net new dwelling rather than replacing one, it keeps the 50% CGT discount and existing negative gearing treatment, with the option to switch to indexation if that works out better. The negative gearing piece is largely moot, because SDA tends to run positive from year one anyway. The CGT treatment is what counts, and SDA's return rides on government-supported, CPI-linked income rather than speculative growth. That makes the after-tax outcome far less sensitive to where the property cycle happens to sit on the day you sell.
| Aspect | Established residential | New-build SDA |
|---|---|---|
| Negative gearing (post 1 Jul 2027) | Losses deductible against property income only, not wages | Rarely an issue (SDA is usually positively geared); rule retained on new builds in any case |
| Capital gains tax | New inflation-indexed model + 30% minimum, no choice | Choice of 50% discount or new inflation-indexed regime |
| Primary return driver | Speculative market capital growth (cyclical) | Government-supported, CPI-indexed rental income |
| Sensitivity to market timing | High, depends on the property cycle | Low, income-led not growth-led |
| Alignment with reform intent | Penalised (established stock) | Favoured (new supply) |
The reason the budget improves SDA's relative position is simple enough. The same legislation that makes established residential less efficient leaves new-build SDA's benefits intact and hands it a second option on top. The negative gearing and CGT changes due in 2027 were built to push capital out of established housing and into new supply. SDA is new supply. The policy and the product happen to want the same thing.
Two things to keep an eye on, neither a threat
None of this is a crystal ball, and legislation can shift on its way through the Senate. Two items are worth watching, and neither one threatens the SDA position.
SIL commissioning consultation, from July 2026. Supported Independent Living, the support service delivered alongside SDA dwellings, is moving to a commissioned model, with full implementation by July 2028. SIL is the service that sits next to SDA, not SDA itself. The reform is expected to consolidate the SIL market toward larger, better-capitalised operators, which is genuinely good for SDA owners. Your long-term tenancy outcome depends on having a viable SIL partner in the dwelling, and well-funded operators are a lot less likely to walk away.
The exposure draft on "new build". Treasury will release the draft legislation defining exactly what qualifies as a new build for the CGT and negative gearing carve-outs. A genuine net-new SDA dwelling should clear any sensible definition, but the knockdown-rebuild line is the one to confirm with your accountant once the wording lands.
The bottom line for SDA investors
The headline number, $37.8 billion, is real, and it does not touch SDA. The cuts hit the operating side of the scheme: plan management, support coordination, community participation budgets, fraud control. The capital accommodation stream, where your investment lives, is left alone. The Pricing Review framework that backs your income is still in place. The NDIA's own demand projections have SDA tracking almost exactly to forecast. Federal SDA funding is still pointed up, which is the gap our SDA investment research is built to close.
On tax, SDA comes out ahead of standard residential property, with the two catches worth repeating. If your project adds a net new dwelling, you get the new-build carve-out and the choice between the old 50% discount and the new indexation regime. A knockdown-rebuild does not qualify. And the negative gearing change largely passes SDA by, because SDA is usually positively geared in the first place.
The honest read: the NDIS budget 2026 SDA outcome strengthens the case for SDA as a long-hold property investment rather than weakening it. Government-supported, indexed income. A protected cohort. Demand on track. Favourable tax treatment for projects that add new supply. The headline was loud. The detail is calm.
Your NDIS budget 2026 SDA questions, answered
Does the NDIS budget 2026 cut SDA funding?
No. The NDIS budget 2026 SDA position is clear once you read the detail: the budget cut $37.8 billion from the NDIS over four years, but the cuts land on operating supports like plan management, support coordination and community participation budgets. SDA is capital funding and sits outside all of that. SDA pricing runs through the existing 2023 to 2028 SDA Pricing Arrangements cycle as planned.
How does the 2026-27 Federal Budget affect SDA as a property investment?
Net positive, though how positive depends on inflation and how long you hold. Your SDA income stays government-supported and CPI-indexed. The eligible cohort is protected by the move to functional-capacity assessment. Pre-budget sector analysis still has federal SDA funding tripling by 2033. And the property tax changes give new builds, which is what SDA is, the choice between the old 50% CGT discount and the new indexation regime, whichever comes out better.
What are the negative gearing changes in the 2026 Australian budget?
From 1 July 2027, negative gearing is limited to new builds. Anything held before budget night (12 May 2026) is grandfathered. Buy established housing after budget night and you can only deduct losses against property income, not your wages. For SDA owners the change barely registers, because SDA is usually positively geared, so there is no loss to offset in the first place.
Does a knockdown-rebuild SDA project qualify as a "new build" for the tax carve-outs?
No. The new-build carve-out exists to grow the total supply of housing. Demolish an existing house and build an SDA dwelling in its place and the dwelling count is unchanged, so the carve-out does not apply. The project has to add a net new dwelling. This will catch a fair share of SDA projects, infill developments in established suburbs especially.
What is the capital gains tax change in the 2026-27 budget?
From 1 July 2027, the 50% CGT discount is replaced by an inflation-indexed cost base with a minimum 30% tax rate on the real gain. Only gains after 1 July 2027 are affected. Investors in qualifying new builds, including SDA projects that add net new supply, can choose between the old 50% discount and the new indexation model.
Is SDA still a good investment after the 2026 NDIS reforms?
Yes. The reforms target operating costs, not the capital accommodation stream. SDA's government-supported, indexed income is untouched, the structural undersupply is still there (the sector estimates around $14 billion of capital needed to deliver 5,000 new dwellings by 2033), and the new property tax rules treat new builds like SDA more favourably than established stock.

Last fact-checked against the primary sources on 18 May 2026. The NDIS reforms are being legislated through the National Disability Insurance Scheme Amendment (Securing the NDIS for Future Generations) Bill 2026, introduced to Parliament on 13 May 2026 and currently working through the Senate. The negative gearing and CGT measures are also subject to legislative passage, and the exposure-draft definition of "new build" for the CGT and negative gearing carve-outs hasn't been finalised yet. Things may shift before any of this becomes law.
