Frequently asked questions
Is the NDIS 90 day claim rule already in force?
Not yet. It is part of the Securing the NDIS for Future Generations Bill 2026, introduced on 14 May 2026, and is scheduled to apply from 1 December 2026 if the Bill passes as drafted. Until then the current claiming window of up to two years still applies. Confirm the enacted commencement date against health.gov.au and the NDIA before relying on it.
When does the 90-day clock start counting?
It is expected to run from the date the support was delivered, not the invoice date or the date you get paid. Each session or shift has its own deadline, so a support delivered on 1 December has a separate 90-day window from one delivered on 15 December, even on the same invoice. Track deadlines at the line-item level and confirm the exact trigger in the final rules.
What happens if a claim is rejected close to the 90-day deadline?
A rejection does not reset the clock. If a claim bounces for a data error on day 80, you may have only the remaining days of the original window to correct and resubmit before the line item expires. This is why claiming within days of delivery — not at month-end — is the safest approach; it leaves buffer for fixing rejected claims.
Can I invoice the participant if I miss the 90-day window?
No. Charging a participant privately for an NDIS support you failed to claim in time risks breaching the NDIS Code of Conduct and your service agreement. A missed claim is lost revenue, not a debt you can transfer to the participant. The only protection is claiming promptly.
Does the rule affect plan-managed claims differently?
Yes, in effect. If you invoice a plan manager, they still have to lodge the claim with the NDIA, so your invoice date is not the claim date. A late invoice eats into their window and can forfeit your payment. Send invoices to plan managers quickly and confirm how they track the 90-day deadline.
