If someone has mentioned "TPAR" to you and you nodded along without actually knowing what it means, you're not alone. Most small business owners outside the accounting world only hear the term when their BAS agent asks for subcontractor details — or when they get an ATO penalty notice.

Here's everything you actually need to know, without the jargon.

What is a TPAR?

TPAR stands for Taxable Payments Annual Report. It's a report you submit to the Australian Taxation Office (ATO) once a year, listing all the subcontractors you paid during the financial year.

For each subcontractor, you need to report:

• Their name and ABN (Australian Business Number)
• Their address
• The total amount you paid them (including GST)
• The GST included in those payments

The ATO uses this information to cross-check that your subcontractors are declaring the income you paid them. It's essentially the ATO's way of catching contractors who don't report cash jobs.

Who needs to lodge a TPAR?

Not every business needs to lodge one. The TPAR applies to businesses that pay contractors for specific types of services.

If your business paid subcontractors for any of the following, you almost certainly need to lodge:

• Building and construction — builders, concreters, electricians, plumbers, tilers, carpenters, landscapers
• Cleaning — commercial and domestic cleaning businesses
• Courier and delivery — courier companies, freight operators
• IT services — software developers, IT consultants, tech contractors
• Security services — security guards, alarm monitoring contractors

The rule is based on the type of service, not the size of your business. If a sole-trader builder paid one subcontractor $500 to do some labouring, that still needs to be reported.

If you're genuinely unsure, the ATO's TPAR eligibility checker takes about 2 minutes to complete.

When is TPAR due?

28 August every year, covering the financial year that just ended (1 July to 30 June).

There are no extensions. The ATO automatically applies failure-to-lodge penalties for missed or late reports. As of March 2025, the ATO began actively issuing penalties for overdue TPARs — over the past five years they've issued $18 million in fines to more than 11,000 businesses.

What changed in August 2025?

Before August 2025, you could lodge a TPAR by mailing a paper form to the ATO. That option was permanently removed from 28 August 2025.

All TPAR lodgements must now be made electronically, either:

1. Via ATO Online Services for Business (free, but requires myGovID and RAM setup)
2. Via SBR-enabled accounting software like Xero, MYOB, or QuickBooks
3. Through a registered BAS agent (they lodge on your behalf)

If you were relying on paper lodgement, you need to switch methods now.

What information do you actually need?

For each contractor you paid, you need:

| Detail | What it is | |--------|-----------| | ABN | Their Australian Business Number | | Name | Legal business name or individual name | | Address | Business or residential address | | Total paid | Gross amount paid including GST | | GST withheld | Usually $0 unless you withheld for no-ABN situations |

The hardest part for most businesses isn't the lodgement — it's collecting this information from subcontractors. Many subcontractors don't respond to requests for their ABN, and some aren't sure of their own business address or legal trading name.

---

What happens if you don't lodge?

The ATO matches TPAR data against contractor income tax returns. If your contractors aren't declaring what you paid them, the ATO notices — and often flags your business for review in the process.

For the business that didn't lodge: the ATO applies a Failure to Lodge (FTL) penalty. For small businesses, this is currently $313 per 28-day period the report is overdue (up to a maximum based on your entity size). It adds up quickly.

The hardest part is collecting the data

The actual lodgement process takes about 10 minutes once you have the data. The problem is getting clean, accurate subcontractor details in time.

Most businesses do one of three things:

1. Email or text subbies asking for their details — and spend weeks chasing non-responses
2. Pay their BAS agent to chase the data — expensive and still slow
3. Guess based on old invoices — and end up with wrong ABNs that trigger ATO errors

SubbieLodge was built specifically for this problem. You create a collection campaign, send subbies a link, and they fill in their own details. ABNs are validated against the ATO register in real time. You download the ATO-format CSV and lodge it yourself or hand it to your BAS agent.

Summary

• A TPAR is a report listing all subcontractors you paid, submitted to the ATO by 28 August each year
• It applies to businesses in building, cleaning, IT, courier, and security
• Paper lodgement was eliminated in August 2025 — digital only from now on
• The hard part is collecting clean subcontractor data before the deadline
• Penalties for missing it start at $313 per 28-day period and compound quickly

If you haven't lodged before and you pay subcontractors — check the ATO eligibility tool today, not the week before August 28.
