TinyBAS Due Dates — free Simpler BAS countdown for Australian sole traders

A single offline HTML page Australian sole traders can bookmark.

It shows the next standard Simpler BAS due date (28 February / 28 April / 28 July / 28 October), a live countdown, the coming quarter schedule, and optional links to TinyBAS if you later want a running G1 / 1A / 1B ledger.

Double-click duedates.html. Works from file://. No account. Dates use your computer’s clock.

Not tax advice. Not an ATO product. Standard quarterly dates only — confirm on ato.gov.au before you lodge.

If you want the ledger that sits under those dates, TinyBAS is a one-time A$19 download: https://payhip.com/b/Bsukb
