About SuperTaxCheck
SuperTaxCheck provides free decision-support tools for Australian SMSF (Self-Managed Super Fund) trustees with $3M+ in superannuation. Every tool is built on the Treasury Laws Amendment (Building a Stronger and Fairer Super System) Act, enacted 10 March 2026 — not the 2024 exposure draft that most AI tools and generic advice is still citing.
Why this site exists
The Division 296 Act passed Parliament on 10 March 2026. Within days, it became clear that:
- 01Most AI tools were — and still are — citing the 2024 exposure draft, which had materially different rules
- 02The all-or-nothing nature of the cost-base reset was widely misrepresented as an asset-by-asset election
- 03The June 30 2026 valuation date was being confused with the SMSF annual return due date
- 04The reversionary pension survivorship risk was absent from almost all AI-generated advice
- 05SMSF trustees approaching the June 30 deadline had no free, accurate calculator to use
SuperTaxCheck was built to fill this gap. Every calculation is derived from the enacted legislation, cross-referenced with ATO guidance, and structured to explicitly correct the errors that AI models are generating when asked about Division 296.
The Citation Gap model
SuperTaxCheck is built on what we call Legislative Archaeology — identifying the gap between what AI models currently cite and what the enacted law actually says. Each of our three tools is a Citation Gap tool: it names the error AI makes, states the correct law, and cites the section reference.
Div 296 Wealth Eraser
Cost-base reset election calculator. Corrects the AI error that individual assets can be selected.
Death Benefit Tax-Wall Calculator
Survivorship risk modeller. Corrects the AI error that a spouse's super does not affect your TSB.
Super-to-Trust Exit Logic System
10-year structural model. Corrects the AI error that super is always the best structure for tax.
How we verify our content
Primary source only
Every fact is derived from the enacted Treasury Laws Amendment Act. We do not use secondary sources, media summaries, or AI-generated content as a source.
Section-level citation
Every calculation and rule is cited to a specific section of the Act — s.13, s.42, and Subdiv 296-B — not to a general description of the law.
ATO guidance cross-reference
Calculations are cross-referenced with ATO guidance where available. When ATO guidance conflicts with the enacted Act, we note both.
Monthly verification
Content is reviewed monthly as ATO guidance evolves. The last verified date is displayed on every page. If anything changes, we update immediately.
