Keep Detailed Records for Every NDIS Service
Accurate documentation underpins compliance and faster resolution of ATO or NDIA enquiries. Maintain service agreements, invoices, and evidence of support delivery (dates, hours/units, support type, location). Include the participant’s details, ABN (and third‑party ABN if plan managed), item codes, amounts, and any GST component. Good records help validate claims and withstand audits; poor records risk repayment of funds and delays. Adopt secure storage and retain records for at least five years. Align your templates with NDIA invoice requirements and the ATO’s business record‑keeping rules to meet tax and super obligations.
Quick checklist (NDIS invoices):
- Participant and provider identifiers, item numbers, dates, quantity, total (AUD)
- Claim type (e.g., travel, non‑face‑to‑face) and GST if applicable
- Evidence of delivery (logs/notes/rosters)
Understand GST‑Free vs Taxable NDIS Supplies
Many NDIS supports are GST‑free when all conditions are met: the participant’s plan is in effect; the supply is a reasonable and necessary support listed in the plan; there is a written agreement identifying the participant and the supports; and the supply is covered by the NDIS GST Determination. If any requirement is not satisfied (e.g., support exceeds plan scope or no written agreement), GST may apply. Review mixed supplies and update accounting systems to apply GST correctly.
Action points:
- Keep signed service agreements (or combined written evidence)
- Confirm supports against the plan’s statement of supports
- Map item codes to GST status in your ledger/ERP
If Delays Happen: Know Your Rights on Interest Charges
Where payment or ruling delays lead to General Interest Charge (GIC), you can request remission. The ATO considers circumstances such as natural disasters, illness, or factors outside your control, and the steps you took to mitigate delay. From 1 July 2025, GIC/SIC are no longer deductible, increasing the cost of carrying tax interest—so early engagement and documentation are vital. Decisions are discretionary; provide evidence and propose a payment plan to strengthen your case.
Private rulings: The ATO aims to issue rulings within 28 days once all information is provided; communicate proactively if matters are complex or timeframes slip.
Getting NDIS tax treatment right—especially GST on supports, invoicing, and GIC remission—protects cash flow and compliance. If you’re unsure whether a service is GST‑free, how to structure service agreements, or how to respond to ATO enquiries, engage an accountant. We’ll help you apply Australian taxation law correctly, prepare compliant invoices and records, and manage any ATO interactions so your lodgements are accurate and on time (in AUD).
