NDIS accounting is not standard small business accounting. The complexity of NDIS financial management catches many new providers off guard, leading to compliance breaches, cash flow problems, and ATO issues that are entirely avoidable. HCPA has supported 10,500+ businesses through NDIS registration and operations, with $2B+ facilitated across our consulting engagements. With 27+ years of leadership in the disability and aged care sector, our consultants have seen every financial mistake NDIS providers make, and we know how to prevent them. Our 99% approval rate across registration and compliance engagements reflects the rigour we apply to every aspect of provider operations, including financial systems.
This guide covers the NDIS-specific accounting requirements every registered provider needs to understand: GST treatment, NDIA payment claims, record-keeping obligations, payroll, and financial reporting. Whether you are starting an NDIS business or have been operating for years, getting your financial systems right protects your registration and your bottom line.
Why NDIS Accounting Is Different
Three features make NDIS accounting fundamentally different from standard business accounting: mixed GST treatment across service types, the unique NDIA payment claim system, and the strict record-keeping requirements tied to the NDIS Practice Standards. Providers who apply standard small business accounting practices to their NDIS operations routinely encounter problems in all three areas.
The mixed GST treatment alone creates significant complexity. Some NDIS services are GST-free, others are not, and the distinction depends on how the service is delivered, who delivers it, and what it covers. Getting this wrong means either overcharging participants (who then cannot use their full plan budget) or undercharging the ATO (which triggers compliance issues at BAS time).
Add to this the NDIA’s payment claim system, which operates outside normal accounts receivable processes, and the audit trail requirements that the NDIS Practice Standards impose, and you have an accounting environment that requires either specialist knowledge or specialist software, or ideally both. Setting up your financial systems correctly from day one is far less costly than fixing them after an audit finding or ATO review.
GST Treatment for NDIS Services
Most disability supports delivered under the NDIS are GST-free under Division 38 of the A New Tax System (Goods and Services Tax) Act 1999. Specifically, Subdivision 38-D covers supplies of disability services that meet defined criteria. This means you do not charge GST on these services, and participants’ plan funds are not eroded by a 10% tax. However, not all services an NDIS provider might deliver are automatically GST-free, and the boundaries are not always intuitive.
Which Services Are GST-Free
GST-free status under Subdivision 38-D applies to services that meet all of the following conditions: the service is supplied to a person with disability, it is delivered by a registered NDIS provider, and it is covered by the participant’s NDIS plan. The following support types are typically GST-free when delivered under an NDIS plan:
- Personal care and daily living assistance (Core Supports)
- Community participation supports
- Support coordination and specialist support coordination
- Allied health therapy services (occupational therapy, speech pathology, physiotherapy, psychology)
- Behaviour support services
- Supported Independent Living (SIL)
- Transport assistance funded under a participant’s plan
- Assistive technology and home modifications (when funded under the plan)
Which Services Are NOT GST-Free
Services delivered outside the NDIS plan, or services that are clearly not disability supports, are typically taxable at the standard 10% GST rate. Common examples include:
- Administrative consulting or business services not related to participant support
- Non-disability-related transport (such as general taxi services)
- Services delivered to people who are not NDIS participants
- Sale of goods that are not assistive technology (e.g., general retail items)
- Training or consulting services delivered to other organisations (not to participants)
Mixed Supply Considerations
Many NDIS providers also deliver services that are not NDIS-funded. For example, a provider might deliver NDIS-funded occupational therapy (GST-free) alongside private-pay occupational therapy for clients who are not NDIS participants (standard GST applies). This creates a “mixed supply” situation that requires careful separation in your accounting system. Every service type you deliver needs to be correctly coded as either GST-free or taxable. Your accountant or bookkeeper must understand the Division 38 framework, not just standard GST rules. Misclassification in either direction creates problems: underpayment of GST is an ATO compliance issue, and overcharging GST to NDIS participants can be a breach of the NDIS Pricing Arrangements.
NDIS Billing: Line Items, Service Bookings, and Claims
Understanding the NDIS billing workflow from service delivery to payment receipt is essential for cash flow management. The process works differently from standard invoicing and requires familiarity with several NDIS-specific concepts.
Line Item Billing Explained
NDIS billing uses a line item system where every service you deliver is matched to a specific support item reference number from the NDIS Pricing Arrangements and Price Limits document. Each line item has a defined maximum price, a unit of measure (typically per hour, per day, or per item), and rules about when it can be claimed. For example, “Assistance with Daily Life – Standard – Weekday Daytime” has a different support item number and price limit than “Assistance with Daily Life – Standard – Saturday.” Your billing system must track these line items precisely. Using the wrong support item code results in rejected claims and delayed payments.
Service Bookings vs Claims
A service booking is the mechanism that reserves funding in a participant’s plan for your services. For agency-managed participants, you create a service booking in the myplace provider portal that allocates a portion of the participant’s plan budget to your organisation. Claims are then submitted against that service booking as you deliver services. You cannot claim against a participant’s plan without an active service booking. If your service booking expires or runs out of allocated funds, claims will be rejected. Monitoring service booking balances and renewing them before they expire is a critical cash flow management task.
PRODA and the NDIS Payment Claim System
NDIA payments flow through the PRODA (Provider Digital Access) system, which connects to the myplace provider portal. This is where you submit payment requests for services delivered to agency-managed participants. Understanding how this system works is fundamental to your cash flow.
Payment claims must be submitted with the correct support item reference numbers from the NDIS Pricing Arrangements and Price Limits document, which the NDIA updates annually (typically on 1 July). Using the wrong support item code results in rejected claims. Claims must be submitted within the timeframes specified in the NDIS Price Guide (typically within 90 days of service delivery, though this varies). Late claims can be rejected, resulting in unrecoverable revenue loss.
Reconciling NDIA remittances against your claims requires a clear process. The NDIA pays in bulk batches, and matching payments back to individual claims is a routine but important bookkeeping task. Unreconciled claims can mask underpayments, rejected items, or billing errors. Your accounting software should facilitate this reconciliation efficiently. The NDIS Commission’s audit requirements include documentation that supports every payment claim, so your records must be complete and accessible.
Billing Differences: Agency, Plan, and Self-Managed Participants
Your billing process differs significantly depending on the participant’s plan management type, and your accounts receivable system must handle all three models.
Agency-managed participants are billed directly through PRODA/myplace. You submit payment requests to the NDIA, and funds are deposited into your nominated bank account, typically within 3-5 business days. This is the most straightforward cash flow model but requires PRODA access and correct support item coding for every claim.
Plan-managed participants are billed through their plan manager, not directly to the NDIA. You invoice the plan manager, who pays you from the participant’s plan funds. Payment timelines vary by plan manager, typically 10-30 days. Maintain a clear debtors ledger for outstanding plan manager invoices and follow up promptly on late payments. Plan managers are obligated to pay registered providers within a reasonable timeframe under their own NDIS obligations.
Self-managed participants pay you directly, then claim reimbursement from the NDIA themselves. This gives you the most efficient payment option in theory (upfront payment before service delivery is permitted), but you carry the risk of non-payment if the participant does not have funds available. Clear service agreements with self-managed participants, specifying payment terms, are essential.
Record-Keeping Requirements Under the NDIS Practice Standards
The NDIS Practice Standards require registered providers to maintain complete and accurate financial records that support every payment claim. This means a clear audit trail from service delivery to payment claim to bank receipt. Your records must be sufficient for an approved quality auditor to verify your billing accuracy and compliance during your certification or surveillance audit.
At minimum, your record-keeping system should capture: service delivery records (date, time, support worker, participant, service type), participant service agreements (approved supports and budgets), payment claims (submitted claims with support item codes and amounts), and remittance records (NDIA and plan manager payments received). These records must be stored securely and be accessible for at least 7 years, consistent with standard Australian business record-keeping requirements under the ATO’s retention rules.
What the NDIS Commission May Request During Audits
During certification and surveillance audits, approved quality auditors may request access to the following financial records:
- Service delivery logs matching specific participants and date ranges
- Copies of participant service agreements showing agreed supports and pricing
- Evidence that charges are within NDIS Price Guide limits
- Reconciliation of claims submitted against services delivered
- Evidence of financial viability (current financial statements, cash flow projections)
- Payroll records demonstrating correct employee classification and award compliance
- Insurance certificates (public liability, professional indemnity, workers’ compensation)
For comprehensive guidance on your documentation obligations, see our resource on NDIS policies and procedures. Aligning your financial record-keeping with your broader compliance documentation framework is the most efficient approach.
Financial Reporting for NDIS Practice Standard Compliance
The NDIS Practice Standards include requirements under the Governance and Operational Management module that directly affect your financial reporting. Providers must demonstrate financial viability as a condition of registration. This means your organisation must be able to show it has the financial resources to deliver the services it is registered to provide.
Financial Viability Requirements
The NDIS Commission assesses financial viability during registration and at each audit. Evidence of financial viability typically includes:
- Current profit and loss statements
- Balance sheet showing assets and liabilities
- Cash flow statements or projections
- Evidence of adequate insurance coverage
- Evidence that employee entitlements (wages, superannuation, leave) are being met
Larger NDIS providers (particularly those structured as companies limited by guarantee, incorporated associations, or organisations above certain revenue thresholds) may be required to produce annual audited financial statements. Check your registration conditions and your governing legislation (e.g., the Australian Charities and Not-for-profits Commission Act 2012 for registered charities) to confirm your specific reporting obligations.
Payroll: SCHADS Award and Support Worker Obligations
Support workers in the NDIS sector are typically covered by the Social, Community, Home Care and Disability Services (SCHADS) Award (MA000100). This is one of Australia’s most complex modern awards, with multiple pay classifications, penalty rate structures, and allowance provisions. Getting SCHADS payroll wrong exposes you to Fair Work Act liability and can result in significant underpayment claims.
Key SCHADS Award Obligations
Critical payroll requirements under the SCHADS Award include:
- Pay classifications: Workers must be classified at the correct pay level (Level 1 through Level 8) based on their qualifications, experience, and duties. A support worker with a Certificate III in Individual Support holding responsibilities beyond basic personal care may be at Level 2 or higher, not Level 1.
- Penalty rates: Saturday work attracts 150% of the base rate. Sunday work attracts 200%. Public holidays attract 250%. Evening work (after 8pm) and night work attract additional loadings. These rates apply to all hours worked during the relevant period, not just overtime hours.
- Broken shift allowance: If a worker’s shift includes an unpaid break of more than one hour (common in community-based disability support where there is a gap between morning and afternoon clients), the broken shift allowance applies.
- Travel time between participants: Time spent travelling between participant locations during a shift is paid work time, not unpaid time. Travel costs (per-kilometre reimbursement) must also be paid where the worker uses their own vehicle.
- Sleepover rates for SIL: Supported Independent Living (SIL) often involves sleepover shifts. The SCHADS Award specifies a sleepover allowance plus additional payments if the worker is required to perform work during the sleepover period.
- Superannuation: Currently 11.5% of ordinary time earnings (increasing to 12% on 1 July 2025 as per the legislated schedule). Superannuation must be paid on time to the worker’s nominated fund to avoid the Superannuation Guarantee Charge.
The NDIS workforce relies heavily on casual employees, and the casual conversion provisions of the SCHADS Award require careful management. Regular casuals who have worked consistent hours for 12 months have the right to request permanent employment. Payroll compliance is not just a legal obligation but also a staff retention issue: workers who are underpaid or incorrectly classified leave for providers who manage payroll correctly. Invest in payroll software configured specifically for the SCHADS Award, or engage a payroll service with NDIS sector experience.
BAS Obligations: Quarterly, Monthly, and STP
NDIS providers lodge Business Activity Statements (BAS) on the same quarterly or monthly cycle as other GST-registered businesses. Providers with an annual GST turnover of $20 million or more must lodge monthly. Most NDIS providers lodge quarterly.
Input Tax Credits for GST-Free Businesses
Even though most of your revenue is GST-free, you can still claim input tax credits (ITCs) on business expenses that carry GST. Common claimable expenses include office rent, software subscriptions (Xero, NDIS billing software), motor vehicle costs, professional development and training, marketing and advertising, accounting and legal fees, and office supplies. Many NDIS providers miss this, effectively leaving ATO refunds unclaimed.
The ITC calculation for mixed-supply businesses (GST-free and taxable) uses an apportionment method. Your accountant will calculate the creditable proportion based on your taxable vs. GST-free revenue mix. Ensure your accounting system correctly tracks GST on purchases to support accurate BAS lodgement.
PAYG Withholding
As an employer, you must withhold PAYG tax from employee wages and remit it to the ATO via your BAS. The amount withheld depends on each employee’s tax file declaration and their earnings. Ensure your payroll system calculates withholding correctly, particularly for employees with multiple jobs or salary sacrifice arrangements.
Single Touch Payroll (STP) Phase 2
All NDIS providers must report payroll information to the ATO via Single Touch Payroll (STP) Phase 2. STP Phase 2 requires detailed reporting of gross earnings, tax withheld, superannuation, allowances (including the broken shift and travel allowances common in NDIS payroll), and leave balances. Your payroll software must be STP Phase 2 compliant and configured to report SCHADS Award-specific allowances correctly. Non-compliance with STP obligations can result in penalties from the ATO.
Accounting Software and NDIS Billing Integration
The three most widely used accounting platforms among NDIS providers are Xero, MYOB, and QuickBooks. All three can be configured to handle NDIS-specific requirements, including GST-free income coding and SCHADS payroll. Xero has the broadest ecosystem of NDIS-specific add-ons and integrates with several NDIS billing platforms, making it the most popular choice for providers of all sizes.
End-to-End Billing Workflow with NDIS Software
For providers delivering more than a handful of services per week, manual billing quickly becomes unsustainable. NDIS-specific software platforms automate the billing workflow from service delivery to payment receipt:
- ShiftCare: A rostering and billing platform designed for disability and aged care providers. Support workers log shifts via a mobile app, and ShiftCare automatically generates NDIS-compliant invoices with the correct support item codes and rates. It integrates with Xero and MYOB for automatic accounting synchronisation.
- Lumary: A Salesforce-based NDIS management platform used by larger providers. Lumary handles rostering, service delivery recording, NDIS billing (including automatic PRODA claim submission for agency-managed participants), and financial reporting. It integrates with Xero for accounting.
- SupportAbility: An NDIS practice management platform that handles participant records, service delivery tracking, NDIS billing, and reporting. Integrates with Xero and MYOB.
- Brevity: A purpose-built NDIS software platform covering rostering, case notes, billing, and PRODA integration. Designed for small to mid-sized providers.
The typical end-to-end workflow is: support worker logs shift in NDIS software, the software generates a claim using the correct support item code and rate from the current Price Guide, claims for agency-managed participants are submitted to PRODA automatically (or in a batch), invoices for plan-managed participants are generated and sent to the plan manager, and all transactions sync to your accounting software (Xero/MYOB) for reconciliation and BAS reporting. This automation eliminates manual data entry errors and ensures claims are submitted within the 90-day window.
Choosing an Accountant for Your NDIS Business
Not every accountant understands NDIS accounting. The nuances of Division 38 GST treatment, SCHADS Award payroll, PRODA reconciliation, and NDIS Practice Standard financial reporting requirements are specialist knowledge areas. When selecting an accountant for your NDIS business, look for:
- NDIS industry experience: Ask how many NDIS provider clients they currently service. An accountant with 10+ NDIS clients will have encountered the common issues and know how to handle them efficiently.
- Understanding of the SCHADS Award: Your accountant should know the SCHADS Award pay classifications, penalty rate structures, and allowance provisions. If they have never heard of the SCHADS Award, they are not the right fit.
- Familiarity with NDIS billing software: An accountant who understands how ShiftCare, Lumary, or SupportAbility integrates with Xero or MYOB can set up your chart of accounts correctly from the start.
- Experience with NDIS audit requirements: Your accountant should be able to prepare financial documentation that satisfies NDIS Practice Standard audit requirements, not just ATO requirements.
Typical accounting costs for NDIS providers range from $3,000 to $8,000 per year for small providers (sole traders and small companies) and $10,000 to $25,000+ per year for larger providers with complex payroll and multiple service locations. Bookkeeping services are additional and typically range from $500 to $2,000 per month depending on transaction volume.
Common NDIS Accounting Mistakes to Avoid
The most common NDIS accounting mistakes are predictable and preventable:
- Misclassifying GST on NDIS services: Charging or recording GST on GST-free disability supports, or failing to charge GST on non-NDIS services. Both create ATO compliance issues and potential underpayments or overpayments.
- Not reconciling NDIA remittances against submitted claims: The NDIA pays in bulk batches. If you do not match each payment to specific claims, you will not detect rejected claims, partial payments, or billing errors until it is too late to correct them.
- Late NDIS billing: Claims submitted after the 90-day window are typically rejected. This represents unrecoverable revenue. Providers who bill weekly or fortnightly avoid this issue entirely.
- Poor SCHADS payroll compliance: Incorrect pay classifications, missed penalty rates, unpaid travel time, or incorrectly calculated sleepover allowances. Each of these creates Fair Work liability and potential back-pay claims.
- Inadequate record-keeping: Financial records that cannot support individual payment claims during an audit. If an auditor asks for the service delivery record behind a specific claim and you cannot produce it, this is a compliance finding.
- Not separating NDIS and non-NDIS revenue streams: Providers who deliver both NDIS-funded and privately funded services must separate these revenue streams clearly in their accounting. Commingling makes GST calculations, BAS lodgement, and financial reporting significantly more complex and error-prone.
- Missing input tax credits: Failing to claim ITCs on business expenses because “we are a GST-free business.” You are entitled to ITCs on GST-inclusive purchases regardless of whether your revenue is GST-free.
