About this tool

Tax Deadline Calendar

For an Australian small business, the compliance year isn't one deadline — it's dozens, scattered across the ATO and eight state and territory revenue offices. BAS, PAYG instalments, Single Touch Payroll finalisation, superannuation guarantee, FBT returns, payroll tax reconciliations and income tax lodgements all fall due on their own schedules, and the exact dates shift depending on whether you lodge yourself or through a tax agent, whether you report monthly or quarterly, and which state you employ people in. Missing one isn't just admin friction — late lodgement can trigger ATO penalties and interest. The Tax Deadline Calendar pulls these obligations into a single, ordered view built around your entity type and location, so nothing important sits in a blind spot.

How it works

You tell the tool three things — what kind of taxpayer you are (company or trust, sole trader or partnership, employer with a payroll focus, or an individual), which state or territory you operate in, and which financial year you want to see. From those inputs it assembles the set of obligations that actually apply to you: an individual sees income tax only, while a company or employer sees the full stack of BAS, PAYG, STP, super, FBT and the correct state payroll tax reconciliation. Each entry lists the due date, a plain-English description of what has to be lodged or paid, and the relevant late-lodgement consequence. You can toggle obligation types on and off to focus the view, and export the whole set as an .ics calendar file — complete with advance reminders — that drops straight into Outlook, Google Calendar or Apple Calendar. The dates reflect standard quarterly lodgement schedules and current official figures rather than anything hard-coded and forgotten; the tool itself flags that they move for monthly lodgers, tax-agent clients, substituted accounting periods, and any date landing on a weekend or public holiday.

Who it’s for

Australian small business owners, sole traders and office managers who juggle multiple ATO and state compliance obligations and want them all mapped to one exportable calendar rather than tracked in their heads.

  • Consolidates the key Australian tax and compliance dates — BAS, PAYG, STP, super guarantee, FBT, payroll tax and income tax — into a single chronological view tailored to your entity type and state.
  • Filters obligations to what actually applies: an individual sees income tax only, while a company or employer sees the full lodgement stack plus the correct state payroll tax reconciliation.
  • Exports the whole calendar as an .ics file with built-in advance reminders, so every deadline lands in Outlook, Google or Apple Calendar rather than living in someone's memory.

Frequently asked questions

Do I need a different calendar if I lodge through a tax agent instead of myself?

Often, yes — tax-agent clients frequently get later concessional due dates than self-lodgers for returns like FBT and company income tax. The tool builds around standard self-lodger schedules and flags where agent dates differ, so treat it as a baseline reference and confirm your specific concessional dates with your agent or the ATO.

Why does the payroll tax date change depending on my state?

Payroll tax is a state and territory tax, not a federal one, so each jurisdiction runs its own annual reconciliation with its own revenue office and its own due date. The calendar shows the reconciliation for the state you select, which is why choosing the right location matters if you employ staff — and if you have payroll across multiple states, each one has its own separate obligation.

What actually happens if I miss a lodgement deadline?

It depends on the obligation, but the ATO can apply a failure-to-lodge penalty that accrues over time up to a cap for a small entity, plus interest on any unpaid amount; unpaid super and late payroll tax carry their own charges and interest. Each entry in the tool notes the relevant consequence so you can see what's at stake, but the practical answer is that most penalties are avoidable simply by having the date in front of you early.
