NDIS / SDA property: tax for investors
This covers the tax treatment of Specialist Disability Accommodation held as an investment. It is not advice on whether SDA is a sound investment, and it does not cover NDIA registration or compliance. The 2026 Budget changes to capital gains tax and negative gearing land squarely on this asset class, so read this alongside our Federal Budget 2026-27 factsheet, which sets out those measures in full.
SDA is taxed as residential property, with two twists that change the numbers materially: the buildings are new and heavily fitted out, which makes depreciation unusually valuable, and the income can be GST-free rather than input-taxed in the right structure. Both advantages are easy to lose by buying the wrong way.

What you are actually buying
Specialist Disability Accommodation is housing built to a regulated standard for participants with extreme functional impairment or very high support needs. The tax analysis follows from three features of how it earns.
Two income streams
An SDA payment from the NDIA, plus a reasonable rent contribution from the participant. Both are rent in substance and both are assessable.
The dwelling must be enrolled
Payments depend on the property being enrolled with the NDIA in a design category and building type. An unenrolled dwelling is simply a house.
It only pays when tenanted
The SDA payment follows an eligible participant. A vacant SDA dwelling earns nothing, and the participant pool for any given design category is small.
Deductions continue only while the property is genuinely available for rent.
Holding costs stay deductible through a vacancy provided the dwelling is genuinely available and you are actively seeking an eligible tenant — keep the evidence: listings with SDA finders, provider agreements, correspondence. What does not hold up is a dwelling withdrawn from the market, held for a related party, or enrolled in a category with no local demand. Given SDA vacancies can run for many months, this is the point where an otherwise sound tax position quietly stops working, and it deserves more attention than the depreciation schedule that usually dominates the sales pitch.
Income and everyday deductions
Nothing exotic here. Both income streams are ordinary assessable income declared in the year received, and the usual rental deductions apply to the extent the property is producing that income.
Declare both streams
The NDIA payment is not a grant or a rebate. It is rent, and it is assessable in full alongside the participant’s contribution.
The usual deductions
Loan interest, provider and management fees, council rates, insurance, repairs, and body corporate levies, all on the normal rules.
Repairs versus improvement
Replacing a failed hoist restores the asset and may be deductible; upgrading the fit-out to a higher design category is capital and depreciates.
Depreciation, and the trap that removes half of it
This is where SDA genuinely differs from an ordinary rental. The building is new, so capital works are available in full, and the specialised fit-out carries far more plant and equipment value than a standard house.
Division 43: the structure
2.5% a year for 40 years on construction cost. Steady, long-dated, and it reduces your cost base for CGT, which section 5 returns to.
Division 40: the fit-out
Ceiling hoists, automated doors and windows, assistive technology, backup power, and heavy-duty climate control. Short effective lives, so the deductions land early.
Get the schedule first
Engage a quantity surveyor who has done SDA before, and do it before the first tenancy. Reconstructing a fit-out after the fact loses detail and therefore deductions.
Since 1 July 2017, second-hand plant and equipment in a residential rental cannot be depreciated by the buyer.
The rule that removed depreciation on previously used plant in residential property applies to SDA like any other house. Buy a purpose-built SDA dwelling new and the hoists, doors and backup power are all claimable. Buy the same dwelling from another investor two years later and that entire category is gone — you keep the Division 43 capital works, but the fit-out deductions that made the numbers work for the first owner do not transfer to you.
This is worth pausing on, because the promotional material for SDA tends to quote first-owner depreciation figures without saying so. It also compounds the resale problem in section 5: the second-hand buyer is valuing the same asset on materially worse tax settings than you enjoyed.
GST: the answer turns on who makes the supply
Residential rent is input-taxed: no GST on the rent, and no credits for the GST in the build. Certain NDIS supports are instead GST-free under section 38-38, which does allow credits. Which one applies to you depends on what you are supplying and to whom.
Leasing the house to a provider
That is a lease of residential premises. Input-taxed, whoever the tenant is. No credits on the construction GST.
Supplying SDA to the participant
A registered provider supplying SDA as a funded support under a participant’s plan, with a written agreement, can fall within section 38-38 and be GST-free.
The difference is not cosmetic
On a $900,000 build the GST is roughly $81,800. Recoverable in one case, a permanent cost folded into your cost base in the other.
A head lease to an approved provider does not, by itself, make your supply GST-free.
It is often said that leasing to a registered SDA provider unlocks the GST on the build. Treat that with caution. Section 38-38 attaches to a supply to the participant of a support in their plan; a landlord who supplies a house to a provider is making a different supply, and the residential premises rules are hard to escape. Recovery generally requires the investor to be the entity making the GST-free supply, which brings registration, provider obligations and a very different risk profile with it.
Two consequences follow if you do go down that path. Your rent becomes GST-free rather than input-taxed, so you are in the GST system with ongoing obligations. And a sale of new residential premises within five years is a taxable supply, with GST withheld by the buyer at settlement. Model the whole cycle, not just the credit on the build.
Capital gains tax after the 2026 Budget
The Budget of 12 May 2026 rebuilt the CGT regime, and new residential property was given an explicit choice that most other assets did not get. SDA is almost always new construction, so this matters.
Until 30 June 2027
Current rules. Individuals and trusts holding more than 12 months get the 50% discount. Companies get no discount at all.
From 1 July 2027
For most assets the discount gives way to cost base indexation with a 30% minimum tax on net capital gains.
New residential property
Investors choose between the 50% discount and indexation plus the minimum tax. Purpose-built SDA generally sits inside this carve-out.
The change bites only on gains accruing from 1 July 2027. Everything accrued before that date keeps the 50% discount.
It is easy to read “the discount is abolished” and assume a cliff on 1 July 2027. It is not one. Gains that accrued before that date keep the 50% treatment even if you sell afterwards, assets sold before it keep the current rules entirely, and pre-CGT gains accrued before then stay exempt. For a property bought today and sold in the 2030s, the answer is a blend, and the new-build choice sits on top of that. Our Budget factsheet sets out the measure in full.
Two things that reduce what you keep
Capital works come back
Every dollar of Division 43 claimed reduces your cost base, so it increases the gain on sale. It is a deferral, not a windfall — and it applies under indexation too.
A thin resale market
Your buyer is another SDA investor, on worse depreciation settings than you had, or someone who will strip the fit-out back to an ordinary house. Both cap the price.
Negative gearing: new builds keep it
The same Budget quarantined negative gearing on established residential property. From 1 July 2027 those losses are deductible only against residential property rental income or capital gains, with the excess carried forward. New builds were carved out.
The trigger time
7:30pm AEST, 12 May 2026. Established property acquired from that moment is caught. Anything acquired earlier, including contracts signed but not settled, is exempt until sold.
Eligible new builds are exempt
Losses stay deductible against other income. With SDA’s front-loaded depreciation, that is the difference between a deduction now and one deferred for years.
Super funds are outside it too
Property in superannuation funds and widely held trusts is exempt from the quarantine, with further carve-outs for build-to-rent and government housing programs.
Read the two measures together and the shape of the incentive is clear enough: the 2026 reforms push residential investment towards new stock, and purpose-built SDA is new stock by definition. That is a genuine advantage, but it is an advantage in tax, and tax has never rescued a property that cannot find a tenant.
Ownership structure and land tax
Structure decides the tax rate, who can use the losses, what land tax you pay, and whether you can borrow at all. It is close to irreversible once the contract is signed, which is why it belongs at the front of the process rather than the end.
Individual or partnership
Simplest, and the only way early losses offset salary directly. Gains taxed at your marginal rate with the 50% discount, and land tax at your own threshold.
Discretionary trust
Flexible distributions and asset protection, but losses are trapped in the trust. Watch the surcharge land tax rates that apply to trust-held land.
SMSF
Concessional rates, but bound by the sole purpose test, the in-house asset rules, and borrowing limits. No related-party occupancy, and no negative gearing against personal income.
Thresholds, trust surcharges and absentee owner surcharges vary by state and by who holds the title.
Land tax is assessed on unimproved land value every year regardless of whether the dwelling is tenanted, so it lands hardest in exactly the periods a vacancy is hurting. In Victoria the trust surcharge rates and the absentee owner surcharge both bite on common SDA structures. Some states provide exemptions or concessions for particular kinds of supported or care accommodation, and whether an SDA dwelling qualifies is a question of the specific exemption wording and the facts — it is worth asking before you buy rather than assuming either way.
Before you sign
Settle the structure first
Entity, land tax exposure and GST position decided together, before contracts. Changing your mind later means duty and CGT.
Buy new, and get the QS schedule
New construction preserves both the Division 40 claim and the new-build concessions. Commission the schedule before the first tenant moves in.
Stress-test a long vacancy
Model 6 and 12 months empty, with land tax and interest still running. If it only works fully tenanted, it does not work.
Read the projections sceptically
Check whether quoted depreciation assumes first ownership, whether GST is treated as recoverable, and what vacancy rate is built in.
How we help
We model an SDA purchase on the settings that will actually apply to you: the structure and its land tax, whether GST is genuinely recoverable in your arrangement, the depreciation profile from a real schedule rather than a brochure, and the after-tax position under both CGT paths now that new builds carry a choice. We would rather show you a deal that does not work than one that only works on paper. Talk to us before you sign.
Glossary of terms
- SDA
- Specialist Disability Accommodation: housing built to a regulated standard and funded by the NDIS for participants with extreme functional impairment or very high support needs. Funding is for the dwelling, not the support workers in it.
- SDA payment
- The amount the NDIA pays for an enrolled dwelling occupied by an eligible participant. Set by NDIA price limits according to design category, building type and location.
- RRC
- Reasonable rent contribution: the amount the participant pays towards the dwelling, generally set by reference to a proportion of their income support payments. Assessable rent in the owner's hands.
- NDIA
- The National Disability Insurance Agency, which administers the NDIS, enrols SDA dwellings and sets the price limits.
- Division 43
- Capital works deductions: 2.5% a year for 40 years on the construction cost of a residential building. Amounts claimed reduce the CGT cost base.
- Division 40

- Cost base
- What the asset cost for CGT, including acquisition and capital costs, reduced by capital works deductions claimed. The gain is proceeds less cost base.
- Quantity surveyor
