What must a tax invoice include in Australia?

A tax invoice must show that it is intended as a tax invoice (the words 'Tax Invoice'), the seller's identity and ABN, the date, a description of the items sold including quantity and price, the GST amount (or a statement that the total includes GST), and — for sales of $1,000 or more — the buyer's identity or ABN. This generator enforces every element before letting you download.

When do I need to include the buyer's details?

When the sale is $1,000 or more (including GST), the invoice must also show the buyer's identity or their ABN. The generator watches your total and makes the buyer fields mandatory the moment you cross the threshold.

How do GST-free items appear on a tax invoice?

If every line is taxable, the invoice can simply state 'Total includes GST of $X'. If the invoice mixes taxable and GST-free lines, it must show which items carry GST — this generator switches to a per-line GST column automatically. If everything is GST-free, it states that no GST has been charged.

How is the GST rounded on invoices?

GST is rounded to the nearest cent (half up). On multi-line invoices you may round per line or on the total, as long as the method is consistent. This generator rounds per line and builds the totals from the same line values, so the maths always reconciles to the cent.

Is my invoice data uploaded anywhere?

No. The generator runs entirely in your browser: the preview, the ABN validation, the maths and the PDF all happen on your device. Drafts save to your own browser's local storage and you can export the invoice as a local JSON file. After the page loads, it makes no network requests at all.

// Why this tool exists

Most invoice templates aren't actually compliant.

An Australian tax invoice has to show specific things — the words "Tax Invoice", your identity and ABN, the date, what was sold with quantities and prices, the GST presented the right way for taxable, mixed or GST-free sales, and the buyer's identity once a sale reaches $1,000. Most templates leave one of those out, and most online generators upload your client data to someone's server. This one enforces every requirement live before it lets you download, validates your ABN with the real checksum, rounds GST exactly, and never sends a byte anywhere — the whole thing runs on your device.

// Questions

Straight answers.

What must a tax invoice include?

Seven things: that it's intended as a tax invoice (the words "Tax Invoice"), your identity, your ABN, the issue date, what was sold — description, quantity, price — the GST amount or a statement that the total includes GST, and for sales of $1,000 or more, the buyer's identity or ABN. The checklist above maps to these one-for-one, and the download stays locked until they all pass.

When are the buyer's details mandatory?

From $1,000 including GST. The generator watches your running total and flips the buyer requirement on automatically the moment you cross it — you'll see the "Buyer" pill switch from optional to required.

How are GST-free lines shown?

Mark any line GST-free and the invoice adapts: all-taxable invoices state "Total includes GST of $X"; mixed invoices switch to a per-line GST column so it's clear which items carry GST; fully GST-free invoices state that no GST has been charged. That's the ATO's expected presentation for each case.

How is GST rounded?

Per line, to the nearest cent, half up — and the totals are built from those same line values, so the invoice always reconciles exactly. Want to double-check a figure? The GST calculator uses the identical arithmetic.

Where does my data go?

Nowhere. Preview, validation, maths and the PDF all happen in your browser. Drafts autosave to your own browser's storage; "Save .json" downloads a file to your machine that you can load back later. After the page loads, the tool makes no network requests at all.

Is this legal or tax advice?

No — it's a formatting and calculation tool built to the ATO's published requirements (verified 26 Aug 2026). For special arrangements — RCTIs, agency billing, industry-specific rules — talk to the ATO or your accountant.
