Understanding PAYG Instalments.

If you're running a business or earning investment income, you’ve likely come across the term PAYG instalments — but many people still aren’t clear on what they are, how they work, or why they're important.


In this article, we break down PAYG instalments and explain what you need to know to stay on top of your tax obligations, avoid penalties, and manage your cash flow with confidence.

 

What are PAYG instalments?

PAYG (Pay As You Go) instalments are regular pre-payments of your tax, made throughout the financial year. They’re designed to help individuals and businesses avoid a big tax bill at the end of the year, by splitting the bill into smaller payments throughout the year.


The system applies if you earn income that hasn’t had tax withheld — for example:

  • Business income (as a sole trader, company, or trust).
  • Investment income (such as rent, dividends, or interest).

Instead of paying your full tax bill at tax time, you pay portions in advance, based on the income you earned last year.

 

How do you know if you’re in the PAYG system?

“How did I get here!?”. This is a question a lot of people have.


You’re automatically enrolled into the system based on your tax return. The ATO will notify you if you’ve entered the PAYG instalment system. This typically happens after you lodge your tax return, and the ATO determines that your income meets the threshold for PAYG.

 

The ATO automatically adds people to the PAYG system if:

  • Your business or investment income is over $4,000 (individuals).
  • You had at least $1,000 in tax payable on your last return.
  • You're not already paying enough tax via PAYG withholding (like employee wages).

If you’re unsure, check your myGov account, or speak with us — we can check your ATO account and confirm your PAYG status.

 

How are PAYG instalments calculated?

Your instalment amount is based on your last lodged tax return. The ATO uses your reported income to estimate your likely tax bill and then splits it into quarterly payments. For example, if your 2023 return showed $60,000 in business income, the ATO will estimate your 2024 tax and issue PAYG instalments based on that.


This is helpful — but not always perfect. If your income is higher or lower this year, you may want to vary the instalment amount.

 

If you’re going to vary your instalment, do it early.

If your income has changed — up or down — you can vary your PAYG instalment to better match your current situation. But there’s a catch… You must lodge the variation before the due date of the instalment.


For example, if your next instalment is due 28 April, you must submit the variation before that date. Once the deadline passes, the amount is locked in — even if your actual income is lower than expected.


Also, varying too low without reasonable basis may result in interest charges or penalties, so always check with your Accountant before adjusting.

 

When are PAYG instalments due?

If you’re in the PAYG instalment system, you usually need to pay quarterly on the 28th of July, October, January, and April. So, four times a year, by or on the 28th of those months. It’s essential to make your payment on time — missing a deadline can result in interest charges or penalties from the ATO.

 

Where to find your PAYG instalment notice.

The ATO won’t always send you a letter in the mail. If you’re an individual or sole trader, your PAYG instalment notices will appear in your myGov account, under your linked ATO services. You must check your myGov inbox each quarter. If you don’t, you could easily miss a payment date — and that can cost you.

If you run a business and use a tax agent or BAS agent, the notice can also be accessed through your business portal or agent’s portal. However, you must check your myGov account and business portal.

 

Opting out of PAYG instalments (spoiler alert: you can’t).

Many clients ask us whether they can opt out of PAYG instalments. The short answer is: no — you can’t simply opt out for convenience.

However, in certain cases, you can request to be removed from the PAYG instalment system entirely. This usually applies if your business or investment income has dropped below the ATO’s threshold and is not expected to return to that level. You or your Accountant can make this request to the ATO, and if they accept it, you may be taken out of the system. Alternatively, if your next tax return shows income below the threshold, the ATO may automatically remove you.

 

The bottom line.

PAYG instalments help smooth out your tax payments across the year — but they only work if you stay on top of the due dates, check your myGov notifications, and update your payment amounts if your income changes.

Starting a business is an exciting milestone, but the paperwork can quickly become overwhelming. At Ascent Accountants, we often see new business owners get caught in the "registration trap"—either registering for everything at once (and creating unnecessary admin) or missing critical deadlines that lead to penalties. Knowing which registrations are mandatory and which are optional depends on your business structure, turnover, and whether you have a team. Here is our high-level guide to the essential registrations you need to consider. 1. The Foundations ABN & TFN. Australian Business Number (ABN): Your ABN is your business’s unique 11-digit identifier. While not strictly compulsory for everyone , you almost certainly need one. Without an ABN, other businesses must withhold 47% of any payments they make to you. Tax File Number (TFN): Sole Traders: You use your personal TFN. Companies, Partnerships, and Trusts: You must apply for a separate business TFN. 2. Tax Registrations (ATO) Goods and Services Tax (GST): You must register for GST if your business has a GST turnover of $75,000 or more ($150,000 for non-profits). If you drive a taxi or provide ride-sourcing services (like Uber), you must register regardless of your turnover. Fuel Tax Credits: If your business uses fuel in heavy vehicles, machinery, or for other eligible activities, you can claim a credit for the excise or customs duty included in the price. Note: You must be registered for GST before you can register for Fuel Tax Credits. 3. Employer obligations when hiring a team. If you’re moving from a "solo-preneur" to an employer, your registration requirements change significantly: PAYG withholding: You must register for Pay As You Go (PAYG) withholding before you make your first payment to employees or certain contractors. This allows you to withhold tax from their wages and send it to the ATO. Superannuation: You don't "register" for super in the traditional sense, but you have a legal obligation to pay the Superannuation Guarantee (currently 12% on July 1, 2025) for eligible employees. We recommend setting up a Superannuation Clearing House to streamline these payments. On 1st July 2026, super will be required to be paid each payday. Workers’ compensation insurance: This is a mandatory insurance policy for almost all employers in Australia. It protects you and your employees in the event of a work-related injury. Each state has different rules; for example, in WA, you must have a policy if you employ anyone defined as a "worker." 4. Business Identity: ASIC If you want to trade under anything other than your own legal name (e.g., "John Smith" vs. "Smith’s Landscaping"), you must register the name with the Australian Securities and Investments Commission (ASIC). Our advice? Don’t over-register too early. We often see clients register for GST before they reach the $75k threshold. While this allows you to claim GST credits on your setup costs, it also means you must lodge regular Business Activity Statements (BAS). Speak with us before you hit "submit" on your registrations. We can help you determine the most tax-effective timing for your specific situation. Contact the team today.

When you find your dream home, the process often feels like a whirlwind of inspections, mortgage documents, and packing boxes. Most buyers are diligent about checking for termites or structural cracks, but there is one significant risk that a physical inspection can’t uncover: legal defects in the property’s title. When it comes to real estate, one of the most effective ways to safeguard your equity is through Title Insurance. What is title insurance? Unlike standard home and contents insurance—which covers future events like fires, storms, or theft—Title Insurance is a specialised policy that protects you against existing but unknown legal risks that occurred before you bought the property. It is a one-off premium paid at the time of settlement that provides cover for as long as you own the home. Despite its value, statistics suggest only about 50% of buyers currently opt-in. How it works: real-world scenarios. Title insurance steps in when "discrepancies" surface after you’ve already moved in. Here are the most common ways it protects you: Illegal building work & conversions: It’s common to find a garage that was converted into a bedroom or a deck built without council approval. If the local council discovers this later and demands you bring it up to code or demolish it, Title Insurance can cover the legal and construction costs. Boundary & encroachment issues: Imagine discovering your fence, garage, or driveway is actually sitting on your neighbour’s land or Crown land. The cost of surveys, new building plans, and reconstruction can be staggering. Title insurance handles these expenses. Unpaid rates or taxes: If the previous owner left behind land tax or council rate debts that weren't discovered during settlement, the policy can cover these outstanding costs. Planning & zoning violations: Protection against loss if you cannot live in the house because it doesn't comply with local zoning laws. Is it worth It? These problems often stay hidden for years. You might buy a house that looks perfect, only to find out it has issues when you apply for your own renovation permits. For a relatively low, one-time fee, Title Insurance offers "peace of mind for your purchase." However, it is not a substitute for due diligence. Before you sign: Consult your conveyancer: They can help you finalise the policy during the settlement process. Research the provider: Ensure the company has a strong history of payouts and longevity in the market. Review the coverage: Understand what is specific to your property type (e.g., strata vs. green title). The Ascent perspective. From a financial planning standpoint, an unexpected $20,000 council-ordered demolition or a boundary dispute can derail your investment strategy. Title insurance is a small price to pay to ensure your property remains a secure asset rather than a legal liability. Are you planning a property purchase? Talk to the team at Ascent Property Co and Ascent Accountants to ensure your tax and financial structures are as solid as the roof over your head.

From 1 July 2026, the way employers make superannuation guarantee (SG) contributions will change. The Australian Taxation Office (ATO) has introduced Payday Super . This reform requires employers to pay super at the same time they pay employees’ wages. This is a significant update to the timing of super payments, and it’s important that your payroll processes and software are prepared well before the new rules commence. For full details, including eligibility and exceptions, see the ATO’s information on Payday Super. Key changes. Current requirements. Under the existing system, employers can make Super Guarantee payments to an employee’s fund up to 28 days after the end of the quarter. SG can be paid quarterly or more frequently (for example, monthly), and the current quarterly due dates are 28 October, 28 January, 28 April, 28 July. From 1 July 2026 Under the new Payday Super regime, Super Guarantee payments must be paid to an employee’s super fund at the same time as paying qualifying earnings (QE) — that is, on the employee’s payday . The payment must be received by the super fund within 7 business days of payday. There are limited exceptions to this 7-day deadline, such as for new employees. What you should do now. To ensure compliance with the new requirements, we recommend the following steps: 1. Review your payroll software and processes Confirm that your current systems can support on-payday super payments. If updates or changes are required, plan for implementation well in advance of July 2026. 2. Adjust internal procedures Update payroll calendars and workflows to align with the new payment timing, and ensure responsibilities and deadlines within your team are clear. 3. Seek advice if needed If you are unsure how the changes affect your business, or if your current setup requires modification, please contact us! We are here to help. 4. Review business cashflow. Ensure that the business cashflow will allow you to pay the superannuation on time, each payday. If not, you’ll need to put plans in place. We’re here to support you. These changes will affect all employers with staff and will require planning and preparation. If you have any questions or need assistance reviewing your systems and processes, please get in touch with the Ascent team.
