How Much Is The Next GST Payment – ATO Due Dates And Guide
Australian businesses anticipating their next Goods and Services Tax obligation face a system where instalment amounts derive from prior financial performance rather than current period estimates. The Australian Taxation Office determines quarterly payment obligations using data submitted in your most recent tax return, issuing these calculations on activity statements at the end of each quarter.
Unlike standard billing cycles, these instalments follow the Australian financial year quarters, with specific due dates falling 28 days after each period concludes. Entities lodging through registered tax agents receive automatic extensions, though certain quarters exclude this benefit due to holiday scheduling.
How is the GST instalment amount calculated?
| Default Rate Types | Quarter Due Dates | Calculation Basis | Access Portal |
|---|---|---|---|
| GIC (5%) or Flat (7%) | 28 Oct, 28 Feb, 28 Apr, 28 Jul | Prior year GST turnover | ATO Calculator |
- Prior-Year Basis: Instalments derive from your latest tax return submission, not current quarter performance.
- Quarterly Distribution: ATO issues activity statements at each quarter’s end with pre-calculated amounts.
- No Separate Lodgment: Payment satisfies the requirement; lodging the instalment notice itself is unnecessary.
- Variation Option: Businesses may vary amounts if actual GST liability differs from estimates.
- Zero Turnover Exception: Entities reporting no activity may qualify for nil payment periods.
- Large Business Monthly: Entities exceeding $20 million annual GST turnover must report monthly.
- Agent Extensions: Electronic lodgment through registered agents triggers automatic two-week deadline extensions.

The subsequent quarter ending December falls due on , accounting for the holiday period without additional extensions. Full scheduling details appear in the ATO GST Instalments Guide.
Monthly Obligations for Large Enterprises
Entities generating $20 million or more in GST turnover must transition to monthly Business Activity Statement cycles. These submissions fall due on the 21st day of the month following the reporting period, with no provision for tax agent extensions.

Businesses lodging electronically through registered tax agents automatically receive a two-week extension for Q1 and Q3 quarters, shifting deadlines to 25 November and 26 May respectively. Q2 retains the 28 February deadline regardless of lodgment method.
Can you vary your GST instalment rate?
Adjusting for Liability Changes
When your actual GST liability diverges from the ATO estimate, you may submit a variation by lodging your activity statement before the instalment due date. This adjustment ensures payments align with current trading conditions rather than historical data. Specific variation procedures are outlined in the ATO Variation Guide.
To vary your instalment amount, complete the relevant section on your activity statement and lodge it by the standard due date. The revised amount replaces the ATO estimate for that quarter.
Minimum Instalment Thresholds
While the system accommodates adjustments, businesses should maintain documentation supporting the varied figure. The ATO may apply general interest charges to shortfalls if varied instalments prove insufficient against final assessed liabilities.
How do you pay your GST instalment?
Reviewing Your Assessment
Access your pre-calculated instalment amount through the ATO online services portal or myGov. The figure appears on your quarterly activity statement or instalment notice, reflecting the ATO’s assessment of your tax position based on prior submissions. Payment options and methods are detailed in the BAS Payment Guide.
Remitting the specified amount by the due date satisfies your obligation. You are not required to lodge the instalment notice separately—payment alone completes the quarterly requirement.

How does the GST instalment system fit into broader Australian tax obligations?

While specific registration thresholds depend on annual turnover criteria defined in tax legislation, the instalment system automatically activates for registered entities meeting activity statement requirements.
