Your business will need to register for GST if your annual turnover is $75,000 or more. You have a choice to register or not if it’s less than that. Mark Chapman Director of Tax Communication at H&R Block explains what you need to know.

You must register for GST if you reach the $75,000 turnover threshold or if it looks likely that you will exceed it. Once you’ve passed the turnover threshold, you must register within 21 days.

Taxi drivers and ride-sharing drivers need to register for and charge GST no matter what their turnover is. Not-for-profit organisations, by contrast, can reach a turnover of $150,000 before they are required to register.

You can register for GST online (and also apply for an ABN) via the Australian Business Register (ABR) website (www.abr.gov.au). You can also register for GST via the Business Portal on the ATO website or H&R Block can help you register.

The ABR is the central registry of Australian business information so as well as getting an ABN and registering for GST you can get a business tax file number (TFN), apply for pay-as-you-go (PAYG) withholding and register your business name.

How does the GST work?

The current rate of GST is 10%. This means that if you charge $100 for your goods or services, your customer will be charged $110. The additional $10 is the GST which needs to be paid to the ATO.

When you buy supplies for your business, you’ll be charged 10% in GST which you can claim back as a credit. At the end of each GST period – usually quarterly but occasionally monthly – you need to account for the GST you’ve collected on your sales minus any that you’ve paid (the credits) on your purchases. The difference is the amount payable (or refundable if credits on purchases exceed debits on sales). You do this by completing a business activity statement and paying the net GST to the ATO

Businesses with a turnover of less than $75,000 are given the choice of registering for GST because if a business is spending extensively on supplies, the business might want to claim the GST credits back. This is particularly the case if GST credits on purchases exceed the GST charged to customers.

GST reporting

A business activity statement (BAS) is used to report all your periodic business tax obligations and entitlements. You need to report all the GST charged on your sales and the credits on your business purchases on your BAS as well as your pay as you go (PAYG) instalments and PAYG withholding tax.

Businesses with a turnover greater than $20 million must complete a BAS on a monthly basis and other businesses can also choose to do this if they prefer (for instance, if there are cash flow advantages to your business). Otherwise, BAS forms are due quarterly.

You must lodge your BAS quarterly by the 28th day of the month following the end of the financial quarter (September, December, March, June). If you lodge monthly, your BAS must be lodged by 21 days after the end of each month.

Accounting for GST

When you make a taxable sale of more than $82.50 (including GST), your GST registered customers must be given a tax invoice in order for them to be able to claim the GST credit. If they request one and you don’t provide it at the time, you have 28 days from their request to give it to them.

Invoices need to display specific information. For sales of $1,000 or more, invoices must display:

• the words ‘tax invoice’
• the seller’s name and ABN
• date of the invoice
• buyer name and ABN or address
• a description of the items sold, the quantity and the price
• the GST amount or that the total amount includes GST.

Invoices for less than $1,000 need to have all the above but not the buyer’s details.

There are two ways to account for GST: the cash basis or the accruals basis.

Businesses with a turnover of less than $2m can choose which method they prefer. Other businesses must use the accruals basis.

If you apply the cash basis, you must account for sales and purchases in the period in which you are paid for sales or pay for purchases. The advantage of this method is that GST reporting is better aligned with cash flow, which can be helpful for small businesses.

If you apply the accruals basis, you must account for sales and purchases in the period in which you invoice sales or receive an invoice for purchases.

GST and income tax deductions

If you are able to claim an income tax deduction for something you’ve bought for the business, you can only claim for the net amount (without the GST). This is to prevent you effectively getting tax relief twice on the same amount.

If there’s no GST credit for that purchase (for example if it’s an ‘input taxed’ item), you can claim an income tax deduction for the gross amount (including the GST).

‘Input taxed’ items do not include a GST component in the price, hence a GST credit cannot be claimed. Examples of input taxed items include rent on residential premises, financial items such as loans, ATM transactions and sales of existing residential premises (excluding new homes or commercial buildings).
