PAYG instalment amounts calculated and lodged correctly.
For businesses with PAYG instalment obligations, we calculate the instalment amount based on your income, track payments, and handle amendments if your income changes. Instalments are calculated and lodged alongside your BAS.
The short answer
An Instalment Activity Statement is the form used to report and pay PAYG income tax instalments to the ATO during the year, letting a business pay its tax progressively rather than in a single amount at year-end. It’s one function of BAS & Tax Compliance within your Finance Hub — part of a connected back office.
The Challenge
Common problems we solve
Instalments stay on the ATO's prior-year figure even though this year's income is different
In a lower-income year, cash is tied up paying instalments that are larger than they need to be
Under-paying instalments leaves an unexpected gap at year-end
The IAS and the accountant's tax planning are not coordinated
What's Included
Here's what you receive
Instalment Calculation
Your PAYG instalment calculated with reference to current-year income, not just the prior-year figure the ATO defaults to.
Variation Lodgement
Where current income differs materially from the assessment, a varied instalment lodged so the amount you pay fits the year.
Payment Tracking
Instalment payments tracked and recorded so you always know what has been paid towards the year's tax.
Accountant Coordination
IAS aligned with your accountant's view of your overall tax position so the instalments and final return work together.
Reconciliation
Instalments reconciled through the year, keeping the year-end tax position clear rather than a surprise.
Why It Matters
How it works
An Instalment Activity Statement is how businesses with PAYG instalment obligations pay their income tax progressively through the year rather than in one lump at year-end. The ATO usually sets an instalment amount based on your prior-year tax, but that figure does not always match how the current year is actually going. If your income has fallen, paying the old amount ties up cash you may need; if it has risen, paying too little leaves a larger bill waiting at year-end. We track your current-year income and calculate the instalment so it reflects where the business is now. Where the current year differs materially from the assumption behind your assessment, we can lodge a varied instalment so you are paying an amount that fits, and coordinate with your accountant so the IAS aligns with your overall tax position. Payments are tracked and reconciled, which keeps year-end straightforward.
