What did Parliament do this year? 2025 Tax legislation status summary

Written by: Sheoni Dunlop | Senior Trainer (Tax) | TaxBanter

You could be forgiven for thinking that Parliament has not done a lot in respect of tax legislation for the 2025 calendar year.

To be fair, given we had the Federal election this year, there were not a lot of sitting days.

Parliament last sat on 27 November 2025 and the next sitting day is expected to be 3 February 2026.

The table included below provides a summary of:

  • Tax related Bills that were introduced in 2024 and either lapsed or received Royal Assent in 2025
  • Tax related Bills that were introduced in 2025 and what their status was as at 4 December 2025


Keep in mind that even though the table shows that the Bill introduced in 2024 proposing to impose the Div 296 tax is not proceeding, the Treasurer has announced changes to the proposed Div 296 measures:
