I'm a subcontractor — why has my income started appearing in my tax return by itself?

You subcontract — framing, site cleans, delivery runs, IT jobs on your own ABN. Every year you add up the invoices yourself, put a figure into the business income section, and hope you haven't missed a payer. This year you log in and some of those payments are already sitting there, with the paying business named next to each one.

That is new, and it is deliberate. It is also where two opposite mistakes get made in the same week: treating the pre-filled figures as your income total, and lodging before they have arrived at all.

What actually changed

Pre-fill has expanded for individuals in business at tax time 2026, and the headline change is that Taxable payments annual report data now flows into your return. Businesses in six service industries have been required for years to report what they pay contractors: building and construction, cleaning, courier, road freight, IT, and security, investigation or surveillance. Government entities report their contractor payments and their grants as well. Until now that information sat on the ATO's side of the desk. Now it is put in front of you while you prepare the return.

Two limits on who sees it. It reaches individual contractors only — if you subcontract through a company, trust or partnership, none of this pre-fills. And myTax populates a maximum of 20 fields, so if more than 20 businesses paid you during the year, the last field carries the aggregate of everything else rather than a name-by-name list.

28 August is the date that matters, not 1 July

The paying business has to lodge its TPAR by 28 August each year. Which means most TPAR data only becomes available after 28 August — the ATO says so plainly, and spells out the consequence of going early: lodging in July or early August means this information may not appear yet, which can lead to omissions, the need for amendments, and repayment of refunds later.

Repayment of refunds is the part worth sitting with for a moment. An amendment that adds income you didn't know had been reported doesn't just tidy up the return — it can turn money that has already been spent into a debt. Self-lodgers have until 31 October, which leaves a comfortable window between the data landing and the deadline. Waiting costs nothing.

What the figures are, and what they aren't

For each payer the pre-fill shows the payer's name and ABN, the date the information became available, whether it is an original or an amended report, the gross amount paid, GST, and tax withheld — the withholding appears for information only and is not pre-filled into a field.

Two notes attached to that gross figure do most of the work. The gross amount includes GST if GST was charged. And amounts you invoiced but were not actually paid during the financial year are not included, because TPAR is reported on a cash basis.

The payment information also isn't mapped to a specific label. It arrives as a summary in the Taxable payments section, with prompting in myTax to help you report it at the right label, and the ATO describes the benefit as placing business income into the correct labels with GST excluded. So the number in the summary and the number that belongs in your return are related rather than identical, and reconciling the two is the job that hasn't gone away.

The first mistake: treating the summary as your income total

There is a long list of payments a business does not report in its TPAR, and every item on it is a hole in your pre-fill. Payments for materials only. Labour that is incidental to a supply of materials. Invoices still unpaid at 30 June. Workers engaged under a labour hire or on-hire arrangement. Payments to employees, which go through Single Touch Payroll instead. Payments where no ABN was quoted, which are reported another way. And private, domestic work — a homeowner renovating their own main residence has nothing to report, so that job is invisible to the pre-fill and entirely assessable to you.

Then there is your own accounting. If you return business income on an accruals basis, cash-basis pre-fill will not match your books, and the ATO has built a path for exactly that: choose the Other reason code and type Accruals in the text box provided. That is the shape of the whole feature — you can check, update and confirm anything before you lodge, but if you change a pre-filled amount you will be asked to select a short reason code explaining why.

The second mistake: assuming a gap means it isn't taxable

Cash jobs and private clients are the obvious version of this, and the ATO leaves no room in it: pre-fill isn't a complete picture, you still need to include all other income not reported through TPAR, and good record keeping remains essential even with the expanded pre-fill.

There is a quieter version too. Only high-quality data is pre-filled, but all of the data may be used for compliance purposes at a later time. A payment that didn't make it into your summary is not a payment the ATO has no record of. The reporting system exists, in the ATO's own words, to identify contractors who are not meeting their tax obligations and to make sure businesses aren't disadvantaged by competitors who don't declare all their income.

This is general information current as at July 2026, not advice about your business. If you subcontract in any of those six industries, the practical order is short: total your income from your own records first, lodge after 28 August, and then use the pre-fill as a check against what you built rather than as the source of it. Where the two disagree, the reason is usually a timing difference or a payer's data entry, and both are far easier to sort out while the year is still fresh in your head.
