My income comes from NDIS and Child Care Subsidy payments — does the ATO already have those figures?

The money comes from the NDIA, or from the Child Care Subsidy, or from Veterans' Affairs. It arrives in batches against a claim reference rather than an invoice, the amounts are set by a price guide you did not write, and in a busy year not one dollar of it comes from anyone you would call a customer.

So the question at lodgment time is a fair one. The government paid it and the government has the record — does the ATO already have the figure, and does that make it somebody else's problem? The first half is yes. The second half is where providers get into trouble.

The agency that paid you hands the file to the ATO

The Government Payments Program is a cross-agency program the ATO runs with the Commonwealth agencies that pay service providers to deliver disability support, aged care and child care. It sits alongside the taxable payments annual report rather than replacing it: TPAR captures payments that businesses report, the GPP captures payments the paying agencies report themselves.

The collection is formal. The ATO published the current data-matching protocol on 18 October 2024 and gazetted the notice in the week commencing 14 October 2024, covering government payments data for the 2023–24 to 2025–26 financial years. The data is obtained under section 353-10 of Schedule 1 to the Taxation Administration Act 1953 — a coercive power, meaning the agencies are obliged to hand it over. As at 3 September 2026 the protocol is still listed as current on the ATO's data-matching protocols page, last updated 31 August 2026.

The agencies currently supplying data are the National Disability Insurance Agency (the NDIS), the Department of Education (Child Care Subsidy), the Department of Health, Disability and Ageing (Aged Care Subsidy and the Hearing Services Program), the Department of Veterans' Affairs (health treatment programs), the Department of Employment and Workplace Relations (VET Student Loans) and the Clean Energy Regulator (the two renewable energy schemes).

What crosses over is not a summary. The identification fields are name, address, phone, email, date of birth, service type, ABN and ACN. The transaction fields are the service provider ID, the name and type of service linked to the program, the value of payments received for the financial year, the count and type of claim, and the withholding and re-credit amount. The ATO estimated it would obtain records for approximately 60,000 service providers each financial year, of whom around 9,000 are individuals — the rest being companies, partnerships, trusts and government entities.

The last year in that range is 2025–26. That is the return sitting on most providers' desks right now.

What the file gets checked against

The protocol names four risks the program looks for, and only one of them is about the income figure. Registration: whether the provider is correctly registered for an ABN, a TFN, GST and PAYG withholding. Lodgment: whether income tax returns, business activity statements or fringe benefits tax returns are outstanding. Correct reporting: the agency's payment data compared against the taxpayer's income records. Payment: outstanding debt, and the provider's payment history and ability to meet tax and super obligations as they fall due.

That order is worth noticing, because the most common problem in this population is not an understated figure. It is a provider who has been paid for two years and has never lodged, or who crossed a registration threshold somewhere in the middle of a growth year and did not stop to check.

Where this income goes on the return

The ATO's general guidance on reporting GPP income runs entity by entity. Individuals and sole traders report it in the business and professional items schedule at item P8 Income, label O — gross payments, labour hire or other specified payments. Companies report it at item 6 Income, label C — other sales of goods and services. Partnerships and trusts report it at item 5 Income, label H — other business income. The ATO notes that reporting can vary with entity type, taxable status and other reporting obligations and income sources, so those labels are a starting point rather than a finished answer for every structure.

Two things commonly got wrong

The first: "my NDIS supports are GST-free, so this income is not taxed." GST-free is a GST answer to a GST question. A supply to an NDIS participant is GST-free only where four conditions are all met — the participant has an NDIS plan in effect, the supply is of reasonable and necessary supports specified in the statement of supports in that plan, there is a written agreement between the supplier and the participant or another person, and the supply is covered by one of the tables in the 2021 NDIS Determination. None of that touches income tax, and the ATO's position on government payments is plain: payments received from providing government services such as healthcare, disability support and child care will generally be assessable income.

The same confusion has a second edge. GST turnover is total business income less the GST included in your sales, sales to associates that are not for payment, sales not connected with an enterprise you run, input-taxed sales, and sales not connected with Australia. GST-free sales are not on that subtraction list. A book of work that is entirely GST-free still counts towards the $75,000 registration threshold, and once you are required to register you have 21 days to do it.

The second: "the ATO has the number, so a wrong return will just get corrected." The protocol says the opposite in terms — the data will not be used to initiate automated actions or activities. It is used to identify risks and trends, to inform how taxpayers are selected for engagement activities, and to enhance the data already received through TPAR. Nothing lands in your return automatically. What can arrive is a letter.

This is general information current as at 3 September 2026, not advice about a particular provider. A sole trader support worker, a company running a centre and a trust delivering aged care genuinely do not get the same answer, and taxable status changes it again.

The useful work before anything is lodged is documentary: the full-year remittance or claim statements from each paying agency, plan-manager statements where a plan is not agency-managed, and records that separate GST-free supplies from taxable ones instead of treating the deposit as one number. Our earlier pieces on whether you need to lodge a TPAR, and on the $1,000 standard deduction and why business income does not attract it, cover the questions next door. Sole trader and ABN returns and small business accounting are two of our four service areas, and the income tax calculator on this site is there while you pull the file together.
