How to register for a tax return deadline extension*

Answer a couple of qualifying questions
Tell us about your tax return history so we can assess whether you may qualify for an extended lodgment date. If your prior year tax returns are up to date and you haven’t yet lodged your 2026 tax return, you may be eligible for an extension. Typically, our existing clients are granted a tax extension.
