New NDIS 90 Day Claiming Rule: What Participants and Providers Need to Know
Currently, NDIS claims and reimbursement requests can be submitted up to two years after a support has been delivered, however this process is now changing.
The NDIA is introducing a new claiming rule that will significantly reduce how long participants and providers will have to submit NDIS claims.
This rule will come into effect for all NDIS participants, whether they are plan managed, self-managed or NDIA-managed.
What's changing in December?
From 1 December 2026, all claims and reimbursements must be submitted to the NDIA within 90 days of the date of the item being purchased or the service being delivered.
Invoices submitted after this period will not be paid by the NDIA unless exceptional circumstances apply.
Importantly, the 90-day timeframe is measured from the date the support was delivered or the item purchased, not the date the invoice was created or sent.
The timer starts on the day the support is provided.
Processing times – NDIA and Plan Partners
It’s also important to know that the 90-day cutoff is the date the invoice must be submitted to the NDIA for processing, which is not the same as the date you submit the invoice to Plan Partners.
While we always aim to process every invoice as fast as we can, our processing times may vary, due to:
- Line-item requirements (Assistive Technology or Short-Term Accommodation).
- We may need to ask the participant or provider for more information.
- The participant may need to approve the invoice.
- We may need to help fix a mistake or error with the invoice.
- We could also be waiting for a response from the participant or provider.
All these things need to happen before we submit the invoice to the NDIA and must all happen within the 90 days, so make sure to factor in this additional time.
What does this mean for participants?
Before 1 December
- If you have any outstanding older invoices and/or reimbursement requests, submit them now. Do not delay, as any claims with a service/purchase date older than 90 days will not be processed and paid post 1 December 2026.
After 1 December
- 90-day claiming limit will apply to all payments and reimbursements.
- Participants should submit reimbursement requests and invoices as soon as possible after supports have been received or an item purchased.
- Provide any supporting documentation that may be required to reduce delays.
- Remember that our processing times are part of the 90-day timeframe.
What does this mean for providers?
Before 1 December
- If you have any outstanding older invoices, submit them now. Do not delay, as any claims with a service/purchase date older than 90 days will not be processed and paid post 1 December 2026.
After 1 December
- 90-day claiming limit will apply to all payments and reimbursements.
- Remember that our processing times are part of the 90-day timeframe.
- Review your invoicing processes to ensure claims are submitted promptly.
- Regular invoicing helps reduce the risk of claims approaching or exceeding the new 90-day limit. It also supports faster payments and helps minimise the likelihood of additional NDIA reviews.
- The NDIA recommends submitting invoices within 14 days of the support being delivered. This may mean a change to how frequently providers process invoices and encouraged to update this before 1 December 2026.

Exceptional circumstances
The NDIA may consider a late claim where exceptional circumstances have prevented it from being submitted on time, which will generally not include scenarios like standard administrative delays.
Find out more about exceptional circumstances here (see section 5).
Important points for future claiming
Whether you're a participant seeking reimbursement or a provider submitting invoices, the key message is simple: do not delay submitting claims for completed supports.
- Submit outstanding claims now
If you have any outstanding claims with service dates older than 90 days, we encourage you to submit them now before the new rules take effect on 1 December 2026. - Remember our processing times are part of the 90 days
Allow time for our invoice processing times, which may include requesting clarifying information or customer approvals. - Submit your invoices regularly
