What should I do if my BAS is overdue?

A practical answer from the Affordable Bookkeeper knowledge centre.

Identify the outstanding periods, gather the records and contact your BAS or tax agent promptly. If payment is also a problem, treat that as a separate issue to discuss with the ATO or your authorised agent.

What this means in practice

Ignoring an overdue statement usually makes the record collection task harder. Start with bank and card statements, invoices, payroll reports and any ATO letters. Your agent can help prioritise the work and explain what is missing. Do not assume an extension, payment arrangement or penalty remission has been granted until it has been confirmed.

Your next steps

  • List the outstanding periods
  • Gather ATO correspondence
  • Collect complete statements
  • Agree a catch-up plan
