Superannuation (Building a Stronger and Fairer Super System) Imposition Bill 2026

# Superannuation (Building a Stronger and Fairer Super System) Imposition Bill 2026 ## What it does This law adds a new tax on investment earnings inside super funds. Most people will pay an extra 15% tax on their fund's earnings, while those with very large balances (over a certain threshold) pay 15% on regular earnings plus an additional 10% on the excess earnings from their large balance. ## Why it matters This is a direct hit to super returns for many Australians—your fund's investment income will be taxed more heavily, which means slower growth over time. It's designed to fund other government priorities, but it reduces what you'll have when you retire. ## Key details - **The tax rate**: 15% on most superannuation earnings; an extra 10% applies to earnings above the "very large balance" threshold (this term is defined in existing tax law but not spelled out in this bill) - **When it starts**: The law kicks in on the first of January, April, July or October after it gets Royal Assent—so the exact date depends on when the Governor-General signs it off - **Who's affected**: Anyone with a superannuation fund, but the extra 10% layer only hits those with very large balances stashed away
