ATO Bas Statement Interest Free Payment Plan
The Tax Office has arrangements for small businesses to pay off activity statement amounts without interest over a period of 12 months if certain qualifying criteria are met.
This is in addition to automatic arrangements for payment plans which can be actioned for debts under $200,000.
The stated criteria for an interest-free arrangement are:
- annual turnover of less than $2 million
- activity statement debt of $50,000 or less, overdue for 12 months or less
- no more than one payment plan default within the last 12 months
- no outstanding activity statement lodgments
- cannot obtain finance (such as a loan) through normal business channels
- can demonstrate ongoing viability.
Payment plans can be setup or managed by contacting the Tax Office online or by phone (or via a tax agent).
The contact links and further details are on this page: Tax Office Payment Plans.
Then to change a plan to interest-free, the ATO advise you to contact their business enquiry line (linked below):
At the time of writing, the business enquiry line published on the page linked above is 13 28 66 between the hours of 8am to 6pm (AEST) Monday to Friday.
The actual due dates for each of your lodgment periods are as advised to you by the Tax Office in the Business Portal, or on the paper form if you still receive it.
The Tax Office encourages electronic lodgment and offers an a conditional 2-week lodgment extension (beyond the Standard due date) for quarterly non-large business electronic self-preparing lodgers.
Electronic lodgements of BAS returns
The Tax Office is pushing hard for some form of electronic lodgement as the default method, instead of paper returns. Once an electronic lodgment has been made by an entity, the Tax Office will discontinue any further issue of paper forms for completion of future returns.
(Note: For information regarding tax return lodgement dates see tax return lodgment dates)
BAS Statement Return Lodgement Dates (Quarterly)
Full payment is also normally due on the normal lodgment date, unless the Tax Office has agreed to a specific arrangement.
BAS Form Generation Dates
Pre-filled forms are usually generated several weeks in advance of the period-end date, and electronic lodgers notified in the portal and by email. Paper forms distributed via snail mail necessarily take a little longer. Click this link to see the BAS form generation dates published by the Tax Office.
Quarterly due dates (other than for the December period due in February) ending on the 28th of the month are generally eligible for an automatic 2-week extension if lodged using online services or via a registered agent – see full eligibility requirements here.
Thus for the June 2020 quarter BAS statement the standard due date of 28 July 2020 is automatically extended until 11 August 2020.

Lodgement Dates – the general rules
The general position with regard to due dates is that from the end of the respective periods:
- quarterly returns must be lodged within 28 days (section 31.8) , and
- monthly returns must be lodged within 21 days (section 31.10)
* Quarterly returns with an original due date of 28th lodged electronically generally qualify for an automatic 2 week extension of time.
Eligibility conditions do not include large businesses and monthly lodgers – with the exception of small businesses lodging monthly with a tax agent – the December due date of 21 January is extended to 21 February.
Penalties are normally automatically calculated for late lodgment.
In general, where the due date falls on a weekend or public holiday, it is automatically moved to the next business day.
See Lodgment and payment dates on weekends or public holidays
Withdrawal of paper BAS returns
From 1 July 2014, once an electronic statement has been lodged through any channel, the Tax Office will no longer issue paper BAS forms. Larger businesses (as defined by a turnover test) must lodge electronically.
Large companies –reform to timing of tax instalments
From 1 January 2014 tax payments arrangements for large companies changed, with the commencement of monthly payments, instead of quarterly. See Larger businesses turnover test and further information here.
Amending BAS returns – correcting errors
GST and fuel tax credits errors can be corrected without penalty on either a current or future BAS return (your choice), subject to time and value limits, and provided you are not already subject to compliance action from the Tax Office.
There are two types of GST errors: credit errors and debit errors. Credit errors can be corrected on a later BAS within time limits.
Debit errors can be corrected on a later BAS within certain time and value limits, and generally only if compliance activity by the Tax Office is not already under way.
The time limit is 4 years.
To correct a GST error, the amount must be included at boxes 1A or 1B on the later BAS.
Records and notes must be kept to explain the correction.
If the correction falls outside the time or value limits, then the BAS return for the period of the correction must be revised, potential leading to penalties plus interest.
See a full explanation and requirements from the Tax Office here: Correcting GST errors.
News (from 1 July 2018): Small businesses automatic penalty relief – once in 3 years – for entities with turnover under $10 million. “Inadvertent” errors discovered by the Tax Office during an audit, will not attract a penalty. This concession cannot be applied for; The Tax Office will automatically grant relief during and audit, not more than once every three years. See details here.
