NDIS Provider Bookkeeping: What You Need to Know
Running a business as an NDIS provider comes with a unique set of financial obligations — from understanding how GST applies to NDIS funding, to managing payroll for support workers and meeting the record-keeping requirements of both the ATO and the NDIS Commission. This guide covers what every NDIS provider needs to know to keep their books in order.
1. Registered vs. unregistered NDIS provider — does it affect your bookkeeping?
The first thing to understand is whether you are a registered or unregistered NDIS provider. This affects who can access your services — and has some implications for your financial administration.
| Provider Type | Who they can support | Regulated by |
|---|---|---|
| Registered provider | Plan-managed, Agency-managed & Self-managed participants | NDIS Quality and Safeguards Commission |
| Unregistered provider | Self-managed and Plan-managed participants only | General consumer law; some Commission obligations still apply |
Regardless of your registration status, your tax and bookkeeping obligations with the ATO remain the same. The NDIS Quality and Safeguards Commission is a good starting point for understanding compliance requirements, while the NDIS website has clear guidance on how to become a provider.
2. Is NDIS funding taxable income?
Yes. Payments you receive for providing NDIS supports are ordinary income and must be declared in your tax return. This applies whether you operate as a sole trader, company, partnership, or trust.
The fact that the money comes from the NDIS does not change your ATO reporting obligations. You still need to track all income received, issue invoices or service agreements, and keep records that support your tax return.
If you are a sole trader providing NDIS supports as your main source of income, you are running a business — and all standard small business tax obligations apply, including GST registration if you meet the threshold.
3. GST and NDIS services — what's taxable and what's not?
This is one of the most commonly misunderstood areas for NDIS providers. The rules depend on the specific type of support you are delivering.
GST-free NDIS supports
Certain NDIS supports are GST-free under the ATO's NDIS GST guidance. Generally, a supply of supports under a participant's NDIS plan is GST-free if:
- The supply is made under an NDIS plan
- The supply is made to an NDIS participant
- The supply is of a kind that can be funded or provided under the NDIS
- The participant has a reasonable and necessary funding allocation for that support
Taxable NDIS supplies
Not all NDIS-related income is GST-free. Administration fees, training services provided to staff rather than participants, and commercial activities that sit outside the scope of a participant's plan may attract GST. Always check the ATO guidance or speak with a registered BAS agent if you are unsure whether a specific supply is GST-free or taxable.
Getting the GST classification wrong on your BAS is one of the most common — and costly — bookkeeping mistakes for NDIS providers. If you are overclaiming GST-free treatment, the ATO can require you to remit the difference plus interest.
Do you still need to lodge a BAS?
Yes, if your total GST turnover (including GST-free supplies) reaches $75,000 per year, you must register for GST and lodge a BAS. GST-free income still counts toward your registration threshold — it just means you won't collect GST on those sales or remit it to the ATO.
For a clear breakdown of the GST registration rules, see the ATO's GST registration guide.
4. The NDIS Price Guide and your invoicing
NDIS-registered providers must charge at or below the rates set in the NDIS Pricing Arrangements and Price Limits (previously known as the Price Guide). Unregistered providers have more flexibility, but plan managers and participants will generally expect pricing to be reasonable and aligned with NDIS rates.
From a bookkeeping perspective, this means your invoices need to:
- Reference the correct NDIS support category and line item
- Clearly state whether GST applies (or that the supply is GST-free)
- Include a valid tax invoice if GST is charged and the amount is $82.50 or more
- Be dated and retained as part of your business records
NDIS participants or their plan managers use your invoices to submit claims to the NDIS portal. Inaccurate invoices lead to delayed or rejected payments — so getting this right matters for your cash flow, not just compliance.
5. Payroll for NDIS providers — support worker obligations
Many NDIS providers employ support workers, either directly or via a combination of employees and contractors. Payroll obligations are one of the most complex areas to manage correctly.
Award rates and minimum entitlements
Most support workers in the NDIS sector are covered by the Social, Community, Home Care and Disability Services (SCHADS) Award. This award sets minimum pay rates, penalty rates for weekend and evening work, overtime, and leave entitlements. The Fair Work Ombudsman provides detailed guidance on employer obligations under the SCHADS Award.
Single Touch Payroll (STP)
If you employ staff, you are required to report payroll information to the ATO every time you run a pay run through Single Touch Payroll (STP). This includes wages, tax withheld, and superannuation information. STP Phase 2 is now mandatory and requires additional detail such as income type, country of tax residency, and disaggregated gross income reporting.
Superannuation
As an employer, you must pay superannuation contributions of 11.5% of ordinary time earnings (rising to 12% from 1 July 2025) for all eligible employees. Super must be paid at least quarterly by the quarterly super due dates — not just at year-end. Late super payments attract a Superannuation Guarantee Charge (SGC), which is non-deductible and carries additional penalties.
Contractors vs. employees
Some NDIS providers engage support workers as contractors rather than employees. The ATO has clear rules about when a worker is an employee for tax purposes — regardless of what your contract says. Misclassifying employees as contractors (known as "sham contracting") can result in significant back-pay, penalties, and ATO audit risk. The ATO's employee vs. contractor decision tool is a useful starting point.
6. Record-keeping requirements for NDIS providers
NDIS providers face two sets of record-keeping requirements — one from the ATO and one from the NDIS Commission. It is important not to confuse them.
ATO record-keeping requirements
The ATO requires you to keep records that support your income, expenses, and GST claims for a minimum of five years. This includes:
- Tax invoices for all business purchases and sales
- Bank statements and receipts
- Payroll records, including pay slips and STP reports
- PAYG withholding records
- Superannuation payment records
- BAS lodgement records
Full details are in the ATO's record-keeping guide for businesses.
NDIS Commission requirements
Registered NDIS providers also have separate obligations under the NDIS Practice Standards and the NDIS Code of Conduct. These cover participant records, incident reporting, and documentation of support delivery — separate from your financial records.
A common mistake is treating NDIS Commission record-keeping as a separate concern from bookkeeping. In practice, they overlap — participant service agreements, support notes, and invoices all serve as evidence in both financial audits and Commission reviews.
7. Common bookkeeping mistakes NDIS providers make
7.1 Mixing personal and business finances
NDIS funding must be managed carefully. Keeping a dedicated business bank account — separate from your personal accounts — makes reconciliation straightforward and is essential if you are ever audited.
7.2 Incorrect GST treatment on invoices
Charging GST on GST-free supports, or failing to include GST when it does apply, creates problems at BAS time. Every invoice should be reviewed to confirm whether the supply is GST-free or taxable before it goes out.
7.3 Paying super late
Super due dates fall quarterly — 28 October, 28 January, 28 April, and 28 July. Late payments attract the SGC, which cannot be claimed as a tax deduction and adds a significant administrative burden. Paying on time, every time, is far simpler than managing an SGC liability.
7.4 Not reconciling NDIS portal payments to invoices
NDIS payments come through the NDIS portal (for agency-managed participants) or from plan managers, and do not always arrive at the same time as the invoice. Keeping a clear reconciliation of what has been invoiced, what has been received, and any outstanding amounts is essential for accurate financial reporting.
7.5 Failing to account for travel and overtime correctly
Under the SCHADS Award, travel time between clients and overtime rates must be paid correctly. These costs need to be tracked per employee and reflected accurately in your payroll. The Fair Work record-keeping requirements specify exactly what must appear on pay slips and in your payroll records.
