What’s the go with PAYG instalments?

Jess Sluggett • January 28, 2025

Pay As You Go (PAYG) instalments are regular payments toward your current year tax liability. The aim of them is to put aside money toward your tax bill so that when you lodge your tax return there isn’t as much to pay.

Often referred to as just ‘ instalments ’, these tax payments can apply to individuals, companies and superannuation funds earning business and/or investment income.

Individuals earning solely salary and wage income won’t have to pay instalments because tax is withheld from each payment. People and entities who are making losses also won’t have to pay instalments as they generally will not have a tax bill at the end of the year.

So, who does need to pay instalments?

The ATO will start issuing instalments for individuals if:

  • You have business or investment income of $4,000 or more in your last tax return, or
  • You had tax payable of $1,000 or more in your last tax return, or
  • The ATO estimates you will have tax of $500 or more for the current year.

Companies and super funds will need to pay instalments if:

  • There was income of $2 million or more in the last tax return, or
  • The ATO estimates the company will have tax of $500 or more for the current year.

How are the amounts payable calculated?

Instalment amounts can either be calculated by the ATO or calculated by the taxpayer.

Where the ATO calculates the amount payable, a payment slip is provided by the ATO, and payment just needs to be made. Usually there are no forms to be completed or lodged.

If the payment amount seems too high or too low, it is possible to vary the amount payable.

Where the taxpayer chooses to calculate their own instalment amount, income needs to be calculated and then a percentage rate is applied to work out how much to pay. A form needs to be lodged as well, and the payment made by the due date.

Payment frequency

Instalments can be paid monthly, quarterly or annually, with quarterly being most common. Quarterly instalments are due as follows:

  • Q1 September – 28 October
  • Q2 December – 28 February
  • Q3 March – 28 April
  • Q4 June – 28 July

Primary producers are often given the option to pay just two instalments – one in April and one in July.

Monthly instalments may apply to large entities, often with income of more than $20 million per year. These are due on the 21 st day of the following month (i.e. January is due on 21 February).

Annual instalments can also be an option for taxpayers with lower tax payable amounts.

Delivery of instalments

This is where things get a little bit tricky with the ATO. In the past, instalments were all orange forms that were posted out, and some still are. They were easy to identify!

The ATO is now pushing for more digital communication, and their preference is for myGov, ‘ATO Online’ and ‘Agent digital’ delivery methods.

The problem we are finding with digital delivery is that clients aren’t finding out about their instalments until right on the due date, or when the instalment becomes overdue (hello text message from the ATO!).

If you are set up for myGov (personal) or ATO Online (business) delivery, please make sure to check your notifications. The myGov app is a great place to do this as it is right in the palm of your hand. ATO Online often sends an email to the contact person on the account.

For taxpayers the ATO have registered for ‘Agent Digital’, there is currently no notifications being sent to clients or accountants. This is resulting in a lot of overdue notices being issued because we don’t know instalments have been issued – and neither do clients!

The team at GTP are working on how to capture these instalments and provide notifications to clients. Unfortunately, there are no easy answers with the ATO! In the meantime, if you feel you may have an instalment due but haven’t heard anything, contact your accountant to check in.

In today's fast-paced business environment, technology can assist by simplifying financial workflows, saving time, and improving overall business performance. That said, deploying technology without a strategy can actually hold a business back. Here are 7 best practices which apply to medium enterprises on this subject. 1. Embrace Cloud-Based Accounting Software Not especially new… but cloud-based Accounting software offers a wide range of features, including automated invoicing, expense tracking, and financial reporting. With real-time access to financial data, leaders can make informed decisions quickly and precisely. Cloud accounting can also reduce the administrative workload and give leaders better visibility into the state of the business. 2. Automate Repetitive Tasks The usual candidates for automation are data entry, invoice processing, payroll calculations, and other repetitive processes. Often this requires automating workflows between different apps (using Zapier, for example) because no single application does everything. In addition to time saving, automation reduces errors, which can be expensive to fix. 3. Implement Online Payment Solutions Online payment solutions allow customers to pay invoices electronically, reducing the need for manual payment processing. Most solutions integrate with Accounting software, further simplifying financial management. In most cases, customers also prefer this approach… and improved customer satisfaction is always a good thing! 3. Utilise Financial Dashboards Financial dashboards provide a visual representation of key financial metrics, so leaders can quickly assess the financial health of the business. This leads to making decisions based on data, versus gut feeling. Different businesses should track different metrics depending on their business goals. 4. Invest in Cybersecurity Cybersecurity is a growing threat. Solutions include implementing firewalls, using secure passwords, and regularly updating software. A data breach can be devastating for a business, including losing the trust of customers when their sensitive information is compromised. 5. Leverage AI Artificial intelligence (AI) streamlines financial management processes by analysing financial data to identify patterns and trends, providing valuable insights. AI-powered tools also automate tasks such as fraud detection and risk assessment. 6. Stay Updated with Regulatory Changes Regulatory compliance is critical in financial management. Compliance management software helps leaders stay up to date ensuring compliance, while avoiding costly penalties. Automation helps businesses simplify and enhance financial management processes. How can you streamline your financial workflows and focus on growing your business?

Achieving “Financial Independence” has always been considered the main aim for investors. Many investors become impatient, or they try to get there too quickly. As a result, they may lose discipline and have to start from scratch again. For many it is like chasing a rainbow they never reach, which could be due to a range of reasons. For those that do succeed, in most cases, it is due to using some basic investment principles, combined with a large dose of discipline. Below are 10 Finance and Investing tips, in no particular order, which should be considered as part of a long-term strategy towards financial independence. 1. Insure your income Your future income earning potential, especially in your early working life, will have a value greater than most assets you own. It therefore makes sense to insure it via an effective income protection policy. If due to illness or injury you were unable to work and lost your regular income, you would be putting all of your long-term financial strategy at risk. These premiums are also tax deductible. 2. Set aside 10% of your income – invest it If you can get in this habit early, then it just becomes automatic. Each time your income increases, the value of your 10% also increases. Invest it for the long-term and let the power of compounding take over! 3. Spend less than you earn Should not need to explain this one, but getting in this habit early, will make your life so much less stressful! 4. The best time to invest is always yesterday Procrastination is the greatest enemy of those seeking financial independence. What are you waiting for? Passive income cannot start until you start investing. There is an abundance of low-cost methods now to start investing into markets, so you really do not have an excuse. 5. Do not try and time the market In reality, timing the market is too hard. If you are worried the market might fall, then spread your initial investment over a number of dates and purchase prices so you can get a spread of purchase costs. If you are investing in sharemarkets, yes, they will fall in value!!!! They always do, but they go up as well. If markets do fall, see that as an opportunity to buy in at a cheaper price. 6. Count your money – regularly! Every month, quarter or six months, keep a schedule of the value of your investment assets (bank accounts, shares, superannuation, rental property, etc). Also keep a record of your liabilities (home loan, credit card, investment loan, personal loans for vehicles, caravans, etc). Measure your net asset position and record which way this is trending. You will know pretty quickly if you are heading the right way. If your net asset position is heading south, you need to change your approach, urgently. If it is continually heading in the right direction, then keep up the discipline, but reward yourself where possible! 7. Use the power of compounding This is the eighth Wonder of the World (ask Albert Einstein!). The power of long-term regular investment may not be apparent at the outset of your investing life, but I can guarantee later in life you will always be thankful for those little acorns (investments) you planted 20, 30 & 40 years ago. Example – put $10,000 away each year for 40 years, earn a 7% return over this time and now have $2,136,000. This capital base can generate over $100,000pa each year in income now! Do some Googling and find a compounding interest calculator! 8. Understand risk. Not investing is just as risky as investing! There are many who will not invest in the sharemarket “because it is too risky.” The share market can be volatile, which means there is definitely a short-term risk due to changes in value. But you need to understand how volatility works. There are also risks in only investing in bank deposits in the long-term. Your Term Deposit balances will remain capital guaranteed, but after taking into account inflation, the value of your deposit actually “loses” value. There are risks everywhere, which include volatility, inflationary, diversification and liquidity risk. But there are ways to address each risk. 9. Become financially literate and realistic You owe it to yourself to not put your head in the sand about investment and finance. Most of the characteristics of being a great long-term investor are based on common sense and discipline. There are some wonderful, basic books to get you started. The Richest Man in Babylon by George S Clason, Rich Dad Poor Dad by Robert Kyosaki, The Millionaire Next Door by Thomas J Stanley. You do not need an International Economics degree to understand these books, but they are great foundations you can use to get you into great investing habits. 10. Tax deductions do not make you wealthy I still see a lot of investments advertised or promoted as providing the investor with huge tax deductions, providing tax savings. My first reaction is a big red flag. Large tax deductions, normally mean tax losses and/or cash outlays. A net tax loss on an investment, does allow you to claim a tax deduction, but you only get back your tax deduction multiplied by your marginal tax rate. You are still likely to be out of pocket. Understand what you are getting yourself into long term. I hope these tips can help you on your investing journey! They have helped me!

What is Medicare levy? The Medicare levy is a small tax most Australians pay to help fund our public health system. It’s 2% of your taxable income and is automatically included in your total tax payable at tax time. Who pays the Medicare levy? Most Australian residents will pay the 2% Medicare Levy, once their income reaches the Medicare threshold as in the chart below. For most taxpayers once they earn $27,222 they will start paying some form of Medicare. However, in certain cases, you might get a reduction or even an exemption from the Medicare levy. For instance, if you meet specific conditions such as being a low-income earner, foreign resident or having a medical exemption, you may qualify for a reduced rate or full exemption.
