ATO Tax Invoice Requirements 2026: A$82.50 & A$1,000 Rules for Sole Traders

Short answer: Under Australian Taxation Office (ATO) tax invoice requirements (GST Act 1999 s 29-70), a GST-registered sole trader must issue a tax invoice within 28 days of a customer’s request for any taxable sale over A$82.50 (including GST). Tax invoices under A$1,000 require 7 statutory details—including the words “Tax Invoice”, your 11-digit ABN, the date, item descriptions, and the 10% GST amount—while tax invoices of A$1,000 or more must also display the buyer’s identity or ABN.

Whether you are a licensed electrician in Sydney, a plumber in Brisbane, or an independent consultant in Melbourne, ATO tax invoice requirements govern two sides of your business every day: how you bill commercial clients so your invoices are paid without 47% No-ABN withholding, and which supplier dockets allow you to claim 10% GST credits (Label 1B) on your quarterly Simpler BAS.

Below is the complete 2026–27 breakdown of the official ATO tax invoice rules, comparing the A$82.50, under A$1,000, and A$1,000 or more thresholds, plus what to put on your invoice if you are not registered for GST.

What are the 3 ATO tax invoice thresholds ($82.50, <$1,000, and ≥$1,000)?

Under Section 29-70 of the A New Tax System (Goods and Services Tax) Act 1999, the Australian Taxation Office divides taxable sales into three dollar tiers based on the GST-inclusive total of the invoice:

ATO Invoice Tier (GST-Inclusive)	Mandatory Elements Required by the ATO	Impact on Buyer’s Simpler BAS (Label 1B GST Credit)
Tier 1: A$82.50 or less (A$75.00 ex-GST)	A formal tax invoice is not required to claim a GST credit; a cash register docket, EFTPOS receipt, or supplier invoice is sufficient	Buyer can claim the 1/11th GST credit on Label 1B using an ordinary receipt or bank/docket proof
Tier 2: Over A$82.50 to under A$1,000	Must show all 7 standard ATO Tax Invoice elements: (1) “Tax Invoice”, (2) Seller’s identity, (3) Seller’s 11-digit ABN, (4) Issue date, (5) Brief description of items, (6) GST amount (or “Total price includes GST”), and (7) Extent to which each sale is a taxable supply	Buyer must hold a valid Tax Invoice at the time of lodging their BAS to claim the GST credit at Label 1B (seller must issue within 28 days of request)
Tier 3: A$1,000 or more (incl. GST)	All 7 elements above PLUS (8) the buyer’s identity (legal/business name) or the buyer’s 11-digit ABN	A hardware-store counter docket over A$1,000 that only says “Cash Sale” without your business name or ABN fails Tier 3 unless your trade account prints your name/ABN on the invoice
Non-GST Registered Sole Trader (<$75k turnover)	Must NOT say “Tax Invoice” (title it “Invoice”), must show your 11-digit ABN, and state “No GST has been charged”	Prevents 47% PAYG No-ABN Withholding on invoices over A$75 while keeping you compliant with GST law

What are the 7 mandatory fields on an ATO tax invoice under A$1,000?

When a GST-registered sole trader issues a bill between A$82.51 and A$999.99 (including GST), the document must clearly show seven pieces of information:

1. Document Title (“Tax Invoice”): The words Tax Invoice must be stated prominently—usually at the top right or top left of the PDF.
2. Seller’s Identity: Your legal name (e.g., Lachlan Reid) or your ASIC-registered business name (e.g., Reid Coastal Electrical).
3. Seller’s 11-Digit Australian Business Number (ABN): Verified on ABN Lookup. Without an active ABN on any sale over A$75 ex-GST, a business client must withhold 47% under PAYG No-ABN rules.
4. Date the Invoice Was Issued: The calendar issue date (which determines the BAS quarter for accrual taxpayers, while cash-basis sole traders use the payment date).
5. Brief Description of Each Item Sold: Including the quantity (where applicable) and the price—for example, “Supply & install 2× 10A weatherproof double power points — $380.00 ex-GST”.
6. The GST Amount Payable (10%): You can either show the exact GST dollar amount for each item, or—if the GST is exactly 1/11th of the total price—include a clear statement that “Total price includes GST” alongside the total GST dollar figure.
7. The Extent to Which Each Sale Is a Taxable Supply: Essential on mixed-supply invoices where some lines carry 10% GST and others are GST-free (for example, re-charging a GST-free statutory council or government inspection fee alongside taxable trade labour).

What extra rule applies to ATO tax invoices of A$1,000 or more?

Once the total invoice reaches A$1,000.00 or more (including GST), the ATO requires an eighth mandatory field:

• The Buyer’s Identity or 11-Digit ABN: Your tax invoice must display the client’s full legal or business name (for example, Harbourside Strata Management Pty Ltd) or their 11-digit ABN, plus the quantities of each item listed.

Why this catches tradies out at Bunnings, Reece, or Sydney Tools: If you buy A$1,320 (incl. A$120 GST) of Milwaukee power tools or copper pipe over the counter and the thermal register docket only prints “Tax Invoice — Cash Customer” without your name or 11-digit ABN, that docket technically fails the A$1,000+ ATO buyer-identity requirement. Always swipe your PowerPass / Trade Account card so your business name and ABN are printed on every purchase over A$1,000.

Worked $AUD comparison: Under A$1,000 vs. A$1,000+ vs. Non-GST Sole Trader Invoice

Here is how three different Australian sole trader invoices look in practice for the 2026–27 financial year:

Invoice Scenario	Subtotal (Ex-GST)	10% GST Line	Total Payable ($AUD)	Required ATO Invoice Wording & Fields
1. GST-Registered Tradie (< A$1,000 Callout)	A$600.00	A$60.00	A$660.00	Title: TAX INVOICE · Seller Name & 11-digit ABN · Date · Item description · "Total includes $60.00 GST"
2. GST-Registered Builder (≥ A$1,000 Progress Claim)	A$4,500.00	A$450.00	A$4,950.00	Title: TAX INVOICE · Seller Name & ABN · Buyer Legal Name & ABN · Quantities & itemised lines · A$450.00 GST
3. Non-GST Registered Sole Trader (< A$75k Turnover)	A$600.00	A$0.00	A$600.00	Title: INVOICE (never “Tax Invoice”) · Seller Name & 11-digit ABN · "No GST has been charged"

How do eInvoicing (Peppol) and Recipient Created Tax Invoices (RCTIs) fit in?

• Recipient Created Tax Invoices (RCTIs): In commercial construction, mining, and subcontracting, a principal contractor may issue the tax invoice on your behalf under a written RCTI agreement—covered in our Australian Recipient Created Tax Invoice (RCTI) guide.
• 5-Year ATO Record Retention: Under Section 382-5 of Schedule 1 to the Taxation Administration Act 1953, you must keep all issued tax invoices and supplier dockets for 5 years in English (or an accessible electronic format such as PDF/photo)—see our ATO 5-year record-keeping guide for sole traders.

Frequently asked questions

When is a tax invoice required in Australia?

Under Section 29-70 of the A New Tax System (Goods and Services Tax) Act 1999, a GST-registered sole trader or business must issue a compliant tax invoice within 28 days of a customer requesting one for any taxable sale of more than A$82.50 (including GST) (A$75.00 excluding GST). For sales of A$82.50 or less, a standard cash register docket, EFTPOS receipt, or invoice is sufficient for the buyer to claim a GST credit on their quarterly BAS.

What if a supplier invoice is over A$82.50 but has missing tax invoice details?

Under Australian Taxation Office guidelines, if a supplier’s document is missing a required tax invoice element—such as their 11-digit ABN or the words “Tax Invoice”—you should first ask the supplier to issue a compliant tax invoice within 28 days. If they do not, the ATO allows you in limited circumstances to treat the document as a tax invoice by verifying the missing details on ABN Lookup (abr.business.gov.au), provided the supplier was actively registered for GST on the transaction date.

Can I issue a tax invoice if I have an ABN but am not registered for GST?

No. If your annual GST turnover is under the A$75,000 registration threshold and you are not registered for GST, you must title your bill “Invoice” rather than “Tax Invoice”, display your 11-digit ABN prominently so commercial clients do not withhold 47% under PAYG No-ABN rules, and include the statement “No GST has been charged” above the total.

What extra detail is required on an ATO tax invoice of A$1,000 or more?

When the total price of a taxable supply is A$1,000.00 or more (including GST), the tax invoice must include all seven standard ATO tax invoice fields plus the buyer’s identity (full legal or registered business name) or the buyer’s 11-digit ABN, along with the quantity or volume of each item supplied. Always swipe your trade card at hardware suppliers so purchases over A$1,000 print your business name and ABN.

How long must Australian sole traders keep tax invoices and supplier dockets?

Under Section 382-5 of Schedule 1 to the Taxation Administration Act 1953, Australian sole traders must retain all issued customer tax invoices and incoming supplier dockets for 5 years from the date the record was prepared or the transaction was completed, whichever is later. Digital PDF invoices and clear smartphone photos of thermal hardware dockets fully satisfy ATO electronic record-keeping standards.
