Changes to minimum tax to add $2.6 billion over five years for feds: PBO

The parliamentary budget officer says the federal government's proposed changes to the alternative minimum tax will generate an additional $2.6 billion in revenue over five years.

The tax aims to ensure high-income earners and trusts don't pay disproportionately less in taxes than other taxpayers. 

The Liberal government proposed in the 2023 budget changes to the alternative minimum tax so that the highest income earners pay the greatest share of the revenue generated from the tax.

The changes, which come into effect in January 2024, would increase the minimum tax from 15 per cent to 20.5 per cent.
