Getting started with tax invoices

What is a tax invoice and when should you send one? This straightforward guide explains the basics for new business owners.

The goods and services tax (GST) is part of the way we do business in Australia.

Tax invoices record the amount of GST paid in a transaction.

The ATO has strict rules and requirements for businesses creating tax invoices.  

The good news is your business can use tax invoices to claim GST credits on purchases.

In this article, we’ll cover:  

  • simple tax invoice explanation 

  • when you need to issue a tax invoice  

  • what to include in a tax invoice  

  • keeping tax invoices for GST credits

  • other common questions  

What is a tax invoice?

A tax invoice is a type of invoice created to record the amount of GST paid on a transaction.

Businesses registered for GST need to create tax invoices upon request from customers.

To stay compliant, tax invoices must include specific details set by the ATO. 

Why are tax invoices necessary?

Tax invoices are important to create and collect because they are:  

  • proof of GST charged 

  • records of GST paid

When do I need to send a tax invoice to a customer?  

As a GST-registered business, if a customer requests a tax invoice, you must provide one within 28 days, unless it is for a sale of $82.50 (including GST) or less.  

Tax invoice vs. receipt vs. regular invoice: What’s the difference? 

Purpose of receipts, invoices, and tax invoices 

While they look similar, receipts, invoices, and tax invoices have different functions: 

Regular invoices 

Receipts 

Tax invoices 

A payment request

Proof of purchase  

Evidence of GST charged on a taxable sale

Tax invoice vs. regular invoice 

While regular invoices request payment, tax invoices are for GST purposes. As a result, tax invoices are subject to stricter ATO requirements. 

If you're not registered for GST, regular invoices don't need tax information.

Regular invoices without GST information should not include the words ‘tax invoice'.  

Tax invoice vs. receipt 

While they might seem similar on the surface, tax invoices and receipts are not the same.

Similarities between tax invoices and receipts:

  • Sellers create both tax invoices and receipts

  • Sellers give receipts or tax invoices to buyers (customers)

  • Receipts and tax invoices both show items purchased

The key difference between a tax invoice and a receipt is that tax invoices have stricter ATO requirements.

A receipt can serve as a tax invoice only if it meets the ATO tax invoice requirements.

Tax invoice requirements 

ATO tax invoice requirements vary depending on the sale price. 

Tax invoice requirements for sales under $1,000 

Tax invoices for sales under $1,000 must include each of the following items:

  • a clear statement that the document is a tax invoice 

  • the seller's identity (business name) 

  • seller's ABN 

  • issue date 

  • itemised list – brief description of items sold, including quantity (if applicable), and the price 

  • GST amount payable (if any) – can be shown separately or, if the GST amount is exactly 1/11 of the total price, as a statement which says, 'Total price includes GST.' 

  • the extent to which each sale on the invoice is a taxable sale 

Tax invoice requirements for sales of $1,000 or more 

In addition to the seller's identity, tax invoices of $1,000 or more also need to include the buyer’s identity or ABN.  

If a tax invoice meets the requirements for sales of $1,000 or more, you can use it for sales of lesser amounts.    

See visual example of tax invoice for $1,000 or more.

Example of a tax invoice over $1,000 showing all required ATO details, including seller and buyer information, GST amount, itemised list, and total price.

The tax invoice example includes essential details, such as:

  • GST included in each line item 

  • a clear statement that the sale is fully taxable (using the text 'The total price includes GST')

  • the buyer’s identity

  • the seller’s identity

Using eInvoicing to send tax invoices 

Invoicing software simplifies invoicing with reusable templates. Invoices are ready to send fast, with the right information for GST compliance. Plus, you have automatic records for sales that include GST, ready at tax time.  

Why should I request tax invoices for my business purchases?  

Tax invoices can allow you to claim credit for GST paid on business purchases. Since GST is 10% of the price of goods or services, tax credits can add up!  

As a business owner, you can request tax invoices from your suppliers. Organised digital records make it easier to claim the credits you’re entitled to. 

Learn more about GST reimbursements and credits.  

Why should I keep tax invoice records?   

You need to keep tax invoices for the following reasons:  

  1. Written evidence of business expenses from your suppliers 

  2. Written evidence of income with GST included in sales 

How long do tax invoices need to be kept for ATO compliance? 

According to the ATO, you must keep tax invoice records for 5 years.  

Record-keeping methods 

Traditionally, you would need to request and file paper-based tax invoices. These days, online accounting and reporting tools can help to keep records long-term. 

Digital bookkeeping tools 

Keep organised digital records so you’re ready for tax time.  

Platforms like MYOB can automatically calculate your tax and GST. Plus, MYOB can lodge your tax reports direct to the ATO. 

With the MYOB Assist app, snap photos of tax invoices on the go or upload images from your camera roll.

How to handle the rounding of GST in Australian tax invoices 

In some instances, the amount of GST will include a fraction of a cent. In these cases, special rounding rules apply. Where there’s more than one taxable sale on a tax invoice, the ATO has two rules: 

  1. total invoice rule  

  2. taxable sale rule 

Customers and their suppliers don't need to use the same rounding rules. 

Total invoice rule  

Under the total invoice rule, you can follow these steps: 

  1. calculate the total 

  2. round GST for each taxable sale to the nearest cent (rounding 0.5 cents upwards) 

Or, in cases where the taxable sales for every item include GST of exactly 1/11 of the price, you can follow these steps: 

  1. add up the GST-exclusive value of each taxable sale 

  2. calculate GST on that amount 

  3. round to the nearest cent (rounding 0.5 cents upwards). 

Taxable sale rule  

For the taxable sale rule, follow these steps: 

  1. you work out the amount of GST for each individual taxable sale 

  2. add up these individual amounts  

  3. round the total to the nearest cent 

Can a purchaser (or recipient) issue a tax invoice? 

Typically, a seller produces the tax invoice. However, in some circumstances, the buyer can issue the tax invoice. The ATO calls this a Recipient Created Tax Invoice (RCTI).  

When can I create an RCTI? 

If you are intending to create an RCTI as the purchaser, you can only do so if: 

  • you and the seller are both registered for GST 

  • you and the seller both agree (in writing) that you will issue the tax invoice, rather than the seller 

  • the agreement is current and effective at the time you issue the RCTI 

  • the Commissioner has determined that the type of goods or services sold under the agreement can be invoiced using an RCTI. 

If you don’t meet all these requirements, you must request tax invoices from the seller. 

Common mistakes to avoid 

Even experienced business owners can slip up with GST record-keeping. Avoid these common mistakes to stay compliant: 

Mistakes to avoid 

Ways to stay compliant 

Failing to provide tax invoices within 28 days of a customer request 

Use invoicing software to make invoicing faster and easier. 

Use a mobile invoicing app to send invoices direct from your phone. 

Forgetting to claim GST credits 

Use financial reporting software that lodges direct to the ATO.  

Work with a qualified financial advisor to ensure you claim all the credits you’re entitled to.

Not requesting tax invoices

Request tax invoices for all business purchases over $82.50 (including GST). 

Losing or missing tax invoices 

Use expense management tools to record tax invoices on the spot.

Use a mobile receipt capture app to take photos of tax invoices on the spot. 

Discarding tax invoice records too early 

Use cloud accounting software to securely store tax invoice records for 5 years. 

Issuing RCTIs without meeting ATO criteria 

Only create RCTIs if you meet all ATO criteria.

Keep a record of the written agreement enabling you to create the RCTI.
