# Australia Independent NDIS Support Worker & Allied Health Sole Trader Guide: ABN Invoice, 0% GST-Free (`s 38-38`) & ATO `88c/km` Deductions (2025–26)

**Short answer: Under A New Tax System (Goods and Services Tax) Act 1999 (s 38-38 Disability Support and s 38-10 Allied Health) and ITAA 1997 (s 8-1 and Div 28), this australia ndis support worker sole trader abn invoice gst guide covers three critical rules: most written-agreement NDIS supports and recognized allied health services are GST-free (0% GST), meaning a GST-registered sole trader charges $0 GST while claiming 100% of Label 1B GST credits on car, fuel, iPad, and insurance costs; client-to-client travel is deductible at 88 cents/km; and every $100 missed costs $32 to $47.**

## Why do Plan Managers reject independent NDIS support worker invoices—and how does `s 38-38` GST-Free status give you cash BAS refunds?

Over `150,000` independent disability support workers, occupational therapists (`OTs`), speech pathologists, physiotherapists, exercise physiologists, psychology/counselling practitioners, and support coordinators operate as **ABN sole traders** across Sydney, Melbourne, Brisbane, Perth, and Adelaide—either billing **Plan-Managed** and **Self-Managed NDIS participants** directly or working through platforms like **Mable**.

Two mistakes cost independent NDIS and allied health sole traders thousands of dollars every year under [Australian Taxation Office (ATO)](https://www.ato.gov.au/businesses-and-organisations/gst-excise-and-indirect-taxes/gst/in-detail/your-industry/health/national-disability-insurance-scheme) rules:

1. **Missing Mandatory NDIS Plan-Manager Fields (`48-Hour Payment Delay vs Rejection`):** Plan managers (`My Plan Manager`, `Plan Partners`, `NIB Thrive`, `Leap in!`) use automated optical scanners. If your PDF invoice is missing your **11-digit ABN**, the **participant's full name and NDIS number**, the **exact NDIS Support Catalogue item number** (e.g., `01_011_0107_1_1` *Assistance with Self-Care Activities — Standard Weekday Daytime*), the **date and hours delivered**, or a clear **`$0.00 GST (GST-Free)`** line, the invoice is automatically quarantined.
2. **The `s 38-38` GST-Free Cash Refund Advantage (`Label 1B` on Simpler BAS):** Under **GST Act section 38-38** (and **section 38-10** for listed allied health professions), NDIS supports are **GST-free (`0%`)** when four conditions are met: (a) the participant has an active NDIS plan in effect; (b) the support is of a kind determined by the Disability Services Minister; (c) it is reasonable and necessary in the participant's plan; and (d) it is made under a **written Service Agreement** stating the support is a reasonable and necessary support specified in the participant's plan.
   - Because **GST-free supplies still count toward the `$75,000` GST turnover threshold** and are *not* input-taxed, once you register for GST (voluntarily under `$75,000` or mandatorily at `$75,000+`), you charge **`0%` GST** on your NDIS invoices (`Label 1A = $0`), yet claim **`100%` of the `1/11th` GST (`Label 1B`)** you paid on fuel, car servicing, iPads, Mable platform fees, and insurance—receiving a **quarterly cash refund from the ATO**!
3. **Evaluability Hypothesis (`Hsee, 1996`) & Loss Aversion ($\lambda \approx 2.25$):** At the **`30%` + `2%` Medicare Levy (`32%`)** or **`37%` + `2%` (`39%`)** Australian resident tax bracket, every **`$100` in unrecorded client-to-client kms, Worker Screening renewals, or PPE dockets** costs you **`$32.00 to $39.00` in extra ATO income tax** (plus **`$9.09` in lost `Label 1B` GST credits** if GST-registered!).

| **Home office for shift progress notes, clinical case notes & NDIS invoicing** | **Home Office Expenses** | **`70 cents per hour`** (`2025–26` ATO Revised Fixed Rate method) or actual business % of power, internet & phone | **`A$224` tax saved** on `1,000 hrs` (`A$700` deduction) |

## How do you bill NDIS Provider Travel (Time vs Non-Labour Kilometres) on your invoice?

Under the **NDIS Pricing Arrangements and Price Limits (`PAPL`)**, billing for travel requires separating **Provider Travel — Time** from **Provider Travel — Non-Labour Costs (Kilometres)** on two distinct invoice lines:

1. **Line 1 — Core / Capacity Building Support Delivered:**
   - Example: `01_011_0107_1_1 — Assistance with Self-Care Activities (Standard Weekday Daytime: 07/11/2026, 09:00–13:00, 4.0 hrs @ $67.56/hr) — $270.24 (GST-Free)`
2. **Line 2 — Provider Travel (Time, capped by MMM zone):**
   - Up to **30 minutes** in Metro/Regional areas (**MMM 1–3**) or **60 minutes** in Remote areas (**MMM 4–5**) travelling directly to the participant (must be agreed in the Service Agreement).
3. **Line 3 — Provider Travel — Non-Labour Costs (Activity-Based Transport / Kilometres):**
   - Use the dedicated NDIS transport support code (such as `01_799_0107_1_1` or `04_590_0125_6_1` for community participation kilometres, typically billed at **`$0.97/km`** per Service Agreement) when driving a participant to appointments or community activities.
   - **Important ATO Tax Rule:** Any per-kilometre reimbursement (`$0.97/km`) paid to you by an NDIS participant or Plan Manager must be included in your **assessable business income** on your tax return—and you then offset it by claiming your **`88 cents/km` (`2025–26`)** or **12-week logbook** deduction!

Check the full vehicle rules in [Australia Car Expenses Cents per Km](/keel/australia-car-expenses-cents-per-km/) and [Australia ATO Car Logbook Guide](/keel/australia-ato-car-logbook/).

## How does the ATO Personal Services Income (`PSI`) rule apply if `80%+` of your income comes from one client or agency?

If you work under an ABN as an independent support worker or allied health contractor, check the **[ATO Personal Services Income (`PSI`) rules](/keel/australia-ato-personal-services-income-psi-sole-trader-guide/)**:
- If you support **multiple independent NDIS participants**, advertise your services publicly (or on Mable/local directories), and maintain your own `$10M+` Public Liability & Professional Indemnity policy, you typically pass the **Unrelated Clients Test** and operate as a **Personal Services Business (`PSB`)**.
- However, if `80% or more` of your ABN income comes from a **single labour-hire agency or single NDIS provider** where you simply work rostered shifts at an hourly rate without supplying equipment or rectifying defects, PSI rules may restrict certain home-occupancy or spouse-payment deductions (though your client-to-client car travel, insurances, and Worker Screening fees remain deductible).

## Worked example: 2025–26 ATO tax return + Simpler BAS refund for an independent NDIS support worker earning `A$82,000`

Suppose a GST-registered independent NDIS support worker in Brisbane bills **`A$82,000` (`0%` GST-Free under `s 38-38`)** across 5 plan-managed and self-managed participants:
- **Gross Assessable Business Income (`Item P8`):** **`A$82,000`** (`Label G1 = A$82,000`, `Label 1A GST on Sales = A$0`)
- **Allowable Business Deductions (`A$14,890` ex-GST) + `Label 1B` Cash BAS Refunds (`A$890`):**
  - **Participant-to-Participant & Community Transport Driving (`5,000 km × 88c/km`):** `A$4,400`
  - **Mable Platform Fees (`A$5,200` ex-GST + `A$520` GST refunded on BAS):** `A$5,200`
  - **iPad Pro & Sensory/Mobility Aid Kit under `A$20,000` Instant Asset Write-Off (`A$1,850` ex-GST + `A$185` GST refunded):** `A$1,850`
  - **Public Liability & Indemnity Insurance, First Aid/CPR, Worker Screening & PPE (`A$2,460` + `A$185` GST):** `A$2,460`
  - **Home Office Progress-Note Administration (`1,400 hrs × 70c/hr`):** `A$980`
- **Total ATO Income Tax + Medicare Levy + BAS Refund Benefit:** **`A$5,655` in combined cash tax savings and quarterly BAS refunds**!

## Frequently asked questions

**Do independent NDIS support workers charge 10% GST on invoices?**
Usually **no (`0%` GST-Free)**, provided you have a **written Service Agreement** with the participant confirming the support is a reasonable and necessary support specified in their active NDIS plan and the service is listed in the **GST-Free Supply (National Disability Insurance Scheme Supports) Determination** under **GST Act section 38-38** (or is a recognized allied health service under **section 38-10**). Always mark those lines **`GST-Free ($0.00 GST)`**.

**Should I register for GST voluntarily if my NDIS turnover is under $75,000?**
Often **yes**! Because NDIS supports under **s 38-38** are **GST-free (`0%`)** rather than input-taxed, registering for GST voluntarily means you still charge your NDIS participants **`0%` GST**, but you can file a quarterly Simpler BAS to claim back **`100%` of the `1/11th` GST (`Label 1B`)** you paid on fuel, car servicing, tyres, iPads, phones, and Mable fees—turning your BAS into a **cash refund** every quarter.

**What happens if my NDIS invoice is missing my 11-digit ABN?**
Under the **Taxation Administration Act 1953 (`Schedule 1, s 12-190`)**, a business or Plan Manager paying an invoice over **`A$75` (excluding GST)** that does not display a valid 11-digit ABN is legally required to withhold **`47%` (`No-ABN Withholding`)**—or freeze payment until a compliant ABN invoice is supplied.

**Can I claim driving from my home to my first NDIS participant of the day?**
Under **ATO Ruling `TR 95/15` and `ITAA 1997 Div 28`**, travel from your home to your **first client's house** is non-deductible private commuting *unless* you are required to transport bulky therapy/mobility equipment (like a portable massage table, hoist, or large sensory/physio kit) that cannot be stored at the client's site, OR you are an itinerant worker shifting between multiple workplaces daily under **TR 95/34**. However, **every kilometre driven directly from Participant A's home to Participant B's home, and every kilometre transporting a participant in the community, is 100% deductible at `88 cents/km` (`2025–26`)**.

**Can I deduct coffees or meals bought for myself while accompanying an NDIS participant on a community outing?**
No. Under **Section 8-1 of the Income Tax Assessment Act 1997**, the ATO strictly classifies food, coffee, and drink consumed by a support worker during a regular daytime shift (even when sitting at a café or restaurant alongside a participant during a community access outing) as a **private non-deductible living expense**—unless you are travelling overnight away from home for work.

**How do I create NDIS line-item invoices and track 88c/km participant trips on iPhone?**
Download **[Keel on the App Store (`$0/mo` Core — 100% Unlimited)](https://apps.apple.com/us/app/keel-invoice-maker-receipts/id6786659713?ppid=8470921a-830e-47a3-abf5-bf0b1cce24ac&pt=127772795&ct=blog_fatura_au-ndis-support-worker-gst&mt=8)**—no trial clock, no credit card, and no bank login required (*you are completely free to keep using your current spreadsheets, or email **mert@usekeelapp.com** and we will set up your NDIS support codes, participant list, and expense records in `.keel` format for `100% Free`*!).
