NDIS Registration Guide
How to become a registered NDIS provider in 2026
The registration process end to end: whether you need to register, how the application and audit work, what it costs, how long it takes, and where applications most often stall. Written by the Splana team from registration work done inside NDIS operations.
Key date
1 October 2026 — Supported Independent Living moves into the mandatory registration group. SIL requires a certification audit, and auditor availability tightens as deadlines approach. If SIL is part of your service mix, treat preparation as a now problem, not a Q3 problem.
The seven steps to registration
Decide whether you must register
Registration is mandatory for some supports (including Specialist Disability Accommodation, Supported Independent Living, and any support involving regulated restrictive practices) and for working with NDIA-managed participants. Unregistered providers can only serve self-managed and plan-managed participants. From 1 October 2026, SIL providers move into the mandatory registration group, so the decision is already made for most SIL operations.
Choose your registration groups
Registration groups define the supports you are approved to deliver, and they set which NDIS Practice Standards you are audited against. Register for what you actually deliver — over-scoping adds audit surface and cost; under-scoping means you cannot bill for work you are doing.
Apply through the NDIS Commission portal
You create an application in the NDIS Commission Applications Portal, supply your organisation details, key personnel, outlets, and the registration groups you want. The Commission then issues an initial scope of audit document that tells you which standards apply and whether you need a verification or certification audit.
Engage an approved quality auditor
You choose and pay an approved quality auditor yourself. Verification audits (lower-risk supports) are largely a desktop review of documents. Certification audits (higher-risk supports such as SIL and SDA) add a site visit, staff interviews, and participant interviews. Quote early — auditor lead times stretch out ahead of deadlines.
Build the evidence, not just the policies
This is where most applications stall. Auditors test whether your documented system matches how the organisation actually runs: incident management, complaints, worker screening records, restrictive practice authorisations, participant plans, and continuous improvement. Downloaded policy templates fail when the records behind them do not exist.
Complete the audit and respond to findings
The auditor submits the outcome to the Commission. Non-conformities come with corrective action timeframes. Closing them out quickly is usually the difference between registration in weeks and registration in months.
Receive your registration and maintain it
The Commission makes the final decision and issues a certificate of registration, typically for three years, with a mid-term audit. Registration is not a one-off project: worker screening, incident reporting, and internal audit cadence all have to keep running.
What NDIS registration costs
Indicative Australian ranges. Auditors set their own fees, so quote at least two before committing.
NDIS Commission application
The Commission does not charge for the registration application itself.
Verification audit
Desktop review for lower-risk registration groups. Varies by auditor and scope.
Certification audit
Required for SIL, SDA and other higher-risk supports. Scales with outlets, groups and staff numbers.
Mid-term audit
Falls due around 18 months into a three-year registration period.
Internal preparation
Documentation, evidence assembly, and staff time. Usually exceeds the auditor invoice.
How long it takes
- Verification audit, documentation ready4–8 weeks
- Verification audit, documentation to rebuild2–3 months
- Certification audit (SIL, SDA, restrictive practices)3–6 months
- First-time registration with no existing system6+ months
Where the time actually goes
- Assembling evidence that matches your documented processes
- Auditor lead times, which lengthen ahead of regulatory deadlines
- Closing out non-conformities after the audit report
Frequently asked questions
How long does NDIS provider registration take?
For a verification audit with documentation already in order, four to eight weeks is realistic. Certification audits for supports like SIL typically run three to six months end to end, and longer if the evidence base has to be built from scratch or auditor availability is tight.
How much does it cost to become an NDIS provider?
The Commission charges no application fee. Your cost is the approved quality auditor: roughly $900 to $2,500 for a verification audit, and commonly $4,000 to $12,000 or more for a certification audit depending on registration groups, outlets and staff numbers. Internal preparation time is usually the larger cost.
Can I be an NDIS provider without registering?
Yes, for some supports. Unregistered providers can work with self-managed and plan-managed participants, but not NDIA-managed participants, and cannot deliver supports that require registration such as SDA, SIL, or supports involving regulated restrictive practices.
What is the difference between verification and certification audits?
Verification is a desktop review of your documents and is used for lower-risk registration groups. Certification is a deeper audit against the full NDIS Practice Standards and includes a site visit plus staff and participant interviews. Your registration groups determine which one applies.
What changes for SIL providers on 1 October 2026?
SIL providers move into the mandatory registration group, meaning SIL cannot be delivered without registration from that date. Because SIL triggers a certification audit, providers who start preparation close to the deadline risk auditor availability becoming the binding constraint.
What are the most common reasons registration applications stall?
Evidence gaps rather than missing policies: incident and complaint records that do not match the documented process, incomplete worker screening registers, restrictive practice authorisations that are not current, and no demonstrable continuous improvement cycle.
