Invoicing for NDIS support workersin Australia

Most NDIS supports are GST-free when a few conditions are met, which changes what your invoice needs to show. Add a plan manager who checks your invoice against the NDIS price schedule before you get paid, and NDIS invoicing has its own shape that a generic sole-trader template does not cover.

No credit card required - 5 free invoices a month. This page is general information, not tax or legal advice - check the NDIS and the ATO for the rules that apply to your situation.

The three ways an NDIS participant's plan is managed, and who you invoice

Sourced directly to ndis.gov.au's own pages for each management type, checked 28 September 2026.

Plan typeSelf-managedWho you invoiceThe participant directlyWhat that means for youThe NDIS pays the participant, who then pays you from their own funding. You can be an unregistered provider, and there is no maximum price - you and the participant negotiate the rate directly.
Plan typePlan-managedWho you invoiceThe participant's plan managerWhat that means for youYou send your invoice to the plan manager, who checks it, claims from the NDIS, then pays you. You can still be an unregistered provider - but your rate has to sit within the NDIS Pricing Arrangements and Price Limits for that support.
Plan typeNDIA-managed (agency-managed)Who you invoiceYou cannot invoice the NDIA directly as an unregistered providerWhat that means for youThe NDIS itself pays providers directly for this funding type, and those providers must be registered with the NDIS Quality and Safeguards Commission. Unregistered providers cannot be used for NDIA-managed supports.

Unregistered providers can invoice self-managed and plan-managed participants. They cannot invoice the NDIS directly for NDIA-managed supports. Most sole-trader support workers work with self-managed or plan-managed participants for exactly this reason. Separately, providers delivering Supported Independent Living or operating an NDIS digital platform became subject to mandatory registration from 1 July 2026 - ndis.gov.au, checked 28 September 2026. That specific change does not apply to general community support work unless you deliver one of those two services.

GST - the part that differs most from other sole-trader invoicing

The ATO states a supply to an NDIS participant is GST-free if all of these are met (you must also be registered for GST for the question to arise at all):

01

Reasonable and necessary

The supply is of a reasonable and necessary support specified in the statement of supports in the participant's NDIS plan.

02

A written agreement

There is a written agreement between you and the participant, or whoever manages their plan and funding, made before you deliver the support.

03

Covered by the Determination

The specific support is covered by one of the tables in the GST-free Supply (NDIS Supports) Determination 2021.

If any of those three is not met, for example no written agreement exists, the support may not qualify as GST-free. Source, ato.gov.au, checked 28 September 2026.

The written agreement is not just a tax formality. It can also set your rate, cancellation terms and travel charges in writing, which is useful if a plan manager or self-managed participant later queries an invoice.

Notes

Support delivered per NDIS plan; written service agreement dated 3 Jun 2026. Invoiced to the participant's plan manager on the participant's behalf - participant name withheld from this invoice per the service agreement. Every line on this invoice is GST-free under s38-38 of the GST Act, which is why no GST line appears below - see the GST-free conditions on this page.

Thank you for your business!

Maria is GST-registered, so the heading reads "TAX INVOICE", even though every line on this document is GST-free. Invio's heading follows the business's own GST-registration status, not whether any particular invoice happens to carry GST. The document itself only shows a GST line when an invoice actually carries GST, so on an entirely GST-free invoice like this one, that row does not appear at all - the reasoning for the GST-free total, and who the invoice is really for, are written into the invoice's own Notes instead.

What this invoice should carry

Business details

Your name or trading name, ABN, phone and email. No NDIS registration number is needed if you are unregistered and invoicing a self-managed or plan-managed client - only registered providers show one.

Invoice identifiers

A sequential invoice number, the issue and due dates, and who you are billing - the participant directly (self-managed) or their plan manager (plan-managed), never the NDIS directly if you are unregistered.

Support and line items

Each support type on its own line, referencing the service agreement, with hours or units delivered. Travel, if agreed in the service agreement, sits on its own line. Note the amount is GST-free and why.

Pricing check

For plan-managed invoices, your rate should sit within the current NDIS Pricing Arrangements and Price Limits for that support category - plan managers check this before paying. Self-managed participants can agree a rate above or below those limits directly with you, since the maximum prices only apply to NDIA- managed and plan-managed supports.

Common mistakes

MistakeNo written service agreement before the support startsWhy it costs youWithout it, the GST-free treatment under s38-38 may not apply, and there is no documented rate if a dispute arises later.
MistakeInvoicing the NDIS directly for NDIA-managed support while unregisteredWhy it costs youUnregistered providers can invoice a self-managed participant or a plan manager, not the NDIS itself for agency-managed supports.
MistakeCharging GST on a support that should be GST-freeWhy it costs youOvercharges the participant or plan manager and creates a reconciliation problem at tax time for both sides.
MistakeA rate above the NDIS Price Limit sent to a plan managerWhy it costs youPlan managers check invoices against the price schedule before paying - an above-cap rate on a plan-managed invoice is likely to be queried or only partly paid.
MistakeNo reference to the service agreement on the invoiceWhy it costs youMakes it harder for a plan manager to verify the claim quickly, which slows down payment.

Common questions about NDIS invoicing

Do I need to charge GST on NDIS support work?
Usually not, if you are registered for GST and all of these are true: the support is a reasonable and necessary support specified in the participant's NDIS plan, there is a written agreement in place, and the support is covered by the NDIS GST-free Supply Determination. If any of those is missing, standard GST rules can apply once you are registered and over the threshold.
What is the difference between invoicing a participant, a plan manager and the NDIS?
A self-managed participant pays you directly from funds the NDIS has already paid them. A plan manager checks your invoice against the price schedule and pays you after claiming from the NDIS on the participant's behalf. NDIA-managed funding is paid by the NDIS to registered providers only - an unregistered provider cannot invoice it directly.
Do I need to be a registered NDIS provider to invoice as a sole trader?
Not for self-managed or plan-managed participants - both allow unregistered providers. You must be registered to be paid for NDIA-managed (agency-managed) supports, and separately if you deliver Supported Independent Living or operate an NDIS digital platform, both of which became subject to mandatory registration from 1 July 2026.
What has to be in my written service agreement for GST-free treatment to apply?
It must show a legally binding obligation for you to deliver the support, and state that the support is one of the reasonable and necessary supports specified in the participant's NDIS plan. It can be a single document or a combination of documents, including emails, letters, receipts or invoices, and can be electronic.
Can I charge above the NDIS Price Limits?
The maximum prices in the NDIS pricing schedules only apply to NDIA-managed and plan-managed supports. A self-managed participant can agree a rate with you above or below those limits directly.
Does Invio print "TAX INVOICE" on a support-work invoice that is entirely GST-free?
Yes, if your business is GST-registered. Invio's heading follows the business's own GST-registration status, not whether a particular invoice happens to carry any GST - so a GST-registered support worker's invoice still reads "TAX INVOICE" even when every line is GST-free.
