Keeping GST records is about to get easier.

New laws introduced by the Government, taking effect on 1 April 2023, have modernised the GST rules for invoicing and record keeping.

You'll no longer need to keep a single physical document holding the supply information, such as a tax invoice, credit note, or debit note. Your transaction records, accounting systems and contractual documents may, in combination, contain all the information you need to support the figures in your GST returns.

You can find more information in the handy online tool under 'Taxable supply information (currently called tax invoices)'.

New terms will come into effect.

The definition of taxable supplies has not changed.

'Taxable supply information' refers to the minimum set of information buyers and sellers need to keep as evidence of a transaction.

Taxable supply information includes tax invoices, but it can also include information held in other forms, such as supplier agreements, contracts, and bank statements.

Sellers can provide taxable supply information to a customer using an automated direct exchange between the buyer's and seller's software, for example PEPPOL eInvoicing:

The taxable supply information you need to provide or keep depends on the value and the type of supply. You can find more information in the handy online tool under ''Taxable supply information (currently called tax invoices)'.

Currently, a valid tax invoice must include the words 'tax invoice' in a prominent place.

You will not need to change the wording of the GST documents your business uses to reflect the new terms. For example, you may continue to provide taxable supply information in a single document marked as a 'tax invoice', however you are not required to include this wording when providing taxable supply information.

The taxable supply information you need to supply or keep depends on the value and the type of supply.

Our handy online tool will help you decide on the records you need to keep when you buy or sell goods or services.
