2023-24 Key Dates for Common Lodgements

As we welcome the 2023-2024 financial year, now is a great time to get ahead and familiarise yourself with the key dates for common lodgements. We have prepared a list of these dates below, but please note that this list is not extensive - there may be other lodgements depending on your specific circumstances or industry.


Single Touch Payroll (STP) Finalisation / Payment Summary

  • Lodge / finalise by 14 July

Single Touch Payroll finalisation declarations will need to be lodged to the ATO by 14 July each year. Please ensure that your Single Touch Payroll finalisation declaration(s) are lodged to the ATO via your payroll software.

For employers that are still reporting payment summaries, generally, you must give each of your workers a payment summary by 14 July each year, even if the withheld amount is nil.

You do not need to provide your employees with payment summaries for information you report and finalise through Single Touch Payroll.


Employers must pay super for eligible employees on time in order to avoid the super guarantee charge. This applies from the day your employees start working for you.

Super payments are due quarterly. Please refer to the table below for the payment due dates.



Payment due date


1 July – 30 September

28 October


1 October – 31 December

28 January

28 April

28 July

When a super due date falls on a weekend or public holiday, your contribution must be received by the fund on or before the next business day.

You can also make payments/contributions more frequently than quarterly (i.e. fortnightly or monthly). If you choose to do so, please ensure that you pay your total super guarantee (SG) contribution for the quarter by the due date.

If you have missed or made late super payments, you may need to pay the superannuation guarantee charge (SGC).

Superannuation Guarantee Charge Statement

Employers who do not pay minimum super contributions by the due date must pay the super guarantee charge (SGC) and lodge a SGC statement by the relevant date below:

Please note that the super guarantee charge is not tax deductible.

Tips For Meeting Your Due Dates

Please find below some tips on how to meet your deadlines and avoid the dreaded ATO letter/phone call to follow up late lodgements or payments:

  1. Set up recurring events or tasks in your email/online calendar. Set a reminder for a week before the due date.
  2. Set time aside to add the due dates relevant to your business in a physical calendar. Perhaps place the physical calendar in clear sight. BLG team members can help ensure that you have all the key dates accounted for, just ask us.
  3. If you have a bookkeeper, request that they remind you of when your lodgements are coming up.
