Do you need to register for GST?

Compare your GST turnover with the ATO threshold: $75,000 for a business, $150,000 for a non-profit organisation.

Registration is required once GST turnover reaches the threshold, and taxi or ride-sourcing drivers must register whatever their turnover.

How GST works in Australia, and where ProfitBooks fits.

GST is a 10% tax on most goods and services sold in Australia, run by the Australian Taxation Office (ATO). Here is what the ATO asks of a registered business, and what ProfitBooks does for each part.

10% on most sales

GST is charged on most goods, services and other items sold or consumed in Australia. Some sales are GST-free. Registered businesses include GST in their prices and claim credits for the GST in their business purchases.

ATO: How GST works ↗
In ProfitBooks

Each item carries its GST treatment, so taxable and GST-free lines can sit on one invoice and the GST adds up correctly.

Register at $75,000 turnover

You must register when your GST turnover is $75,000 or more, or $150,000 for a non-profit. Taxi and ride-sourcing drivers register whatever their turnover. You need an ABN first, and you have 21 days to register once you are required to.

ATO: Registering for GST ↗
In ProfitBooks

Start on the free plan before you register. Add your ABN when it arrives, and keep your customers' and suppliers' ABNs on their contacts.

Tax invoices within 28 days

If a customer asks for a tax invoice, you must give one within 28 days, except for very small sales. It shows that it is a tax invoice, your identity and ABN, the date, what you sold, the GST and which items are taxable. Larger sales also need the buyer's identity or ABN.

ATO: Tax invoices ↗
In ProfitBooks

Invoices show the GST on taxable lines, your business details and the customer's ABN from their contact. Email them as a PDF, a format the ATO accepts.

GST goes on your BAS

On the business activity statement (BAS) you report total sales at G1, GST on sales at 1A and GST credits on purchases at 1B. Amounts are whole dollars, rounded down.

ATO: BAS summary labels ↗
In ProfitBooks

G1, 1A and 1B are worked out from your invoices and bills. ProfitBooks does not lodge with the ATO: you lodge, or your BAS agent does.

Quarterly for most small businesses

Most small businesses report and pay GST quarterly. Businesses with a very large GST turnover report monthly, and businesses registered by choice can report annually.

ATO: When to report and pay GST ↗
In ProfitBooks

Run your GST report for any period: a month, a quarter or the financial year.

Cash or accruals basis

On a cash basis you report GST in the period you are paid or you pay. On an accruals basis you report it in the earlier of the period you invoice, are invoiced or pay.

ATO: Identify your accounting basis ↗
In ProfitBooks

Set your GST accounting basis to cash or accruals, and the BAS figures follow it.

GST accounting in Australia: your questions

What is the best GST accounting software for small businesses in Australia?

ProfitBooks is a good fit for Australian small businesses that want GST tax invoicing, bookkeeping, bank reconciliation and BAS-ready GST figures in one cloud app. It applies GST to taxable sales, handles GST-free and input-taxed items, and has a free plan with no time limit. You do not need accounting training to use it.

Is ProfitBooks suitable for sole traders, tradies and small businesses in Australia?

Yes. Sole traders, tradies, cafes, retailers, contractors and growing small businesses use it for the same jobs: tax invoices with their ABN, expenses with GST credits, bank reconciliation and the GST figures for the BAS. You run your books from a browser or the iOS and Android app, with nothing to install.

Does ProfitBooks help with GST and BAS?

Yes. ProfitBooks records the GST on every tax invoice and purchase bill and prepares the GST figures for your BAS, including G1 total sales, 1A GST on sales and 1B GST on purchases. It does not lodge with the ATO. You lodge the BAS yourself, or give your BAS agent or accountant access to review and lodge it.

Do I need to be registered for GST to use ProfitBooks?

No. You can set up your books and send invoices on the free plan before you register. The ATO says you must register once your GST turnover reaches the GST threshold, and you need an ABN first. When your registration comes through, add your ABN in ProfitBooks so it appears on your tax invoices.

How much does ProfitBooks accounting software cost in Australia?

ProfitBooks has a free Startup plan with no time limit: 1 user, 10 invoices a month, 50 customers and 10 products. Paid plans add more invoices, more users, payroll, multi-currency and auditor access. There are no per-invoice charges. Prices on this page are shown in US dollars, and the full comparison is on the pricing page.

How is ProfitBooks different from MYOB or desktop accounting software?

ProfitBooks runs in the cloud, so you open the same books from any browser or phone instead of one computer with the software installed. It is made for owners who are not accountants: GST is applied as you invoice and 50+ reports update live. Your BAS agent logs in instead of waiting for a backup file.

How does bank reconciliation work in ProfitBooks?

Download your statement as a CSV or Excel file from online banking and upload it to ProfitBooks. Each line is matched to an invoice, bill or expense you have recorded, and anything unmatched is flagged for review. Missing sales or purchases are caught before you prepare your BAS. A month of transactions usually takes about 15 minutes.

Can my BAS agent or accountant work in ProfitBooks with me?

Yes, on paid plans. Invite your BAS agent, bookkeeper or accountant as a user with the access you choose, such as read-only access to reports at BAS time. You and your team keep working in the same live books, so nobody emails spreadsheets. The free Startup plan has one user.

Is my business financial data safe in ProfitBooks?

Yes. ProfitBooks stores your data on secure cloud servers with encryption, automatic backups and role-based access. You decide who sees what: staff can raise invoices without seeing your profit and loss, and your accountant can view reports. Because the books are in the cloud, a lost laptop does not mean lost records.
