SMSF tools

Standalone calculators for the numbers trustees check most. Each one cites the statute it applies and shows its working. They report the rules; they do not know your circumstances. Free, and nothing to sign.

45-day rule checker

ITAA 1936 s 160APHO

Division 296 estimator

ITAA 1997 Div 296

Splits realised earnings across the $3m and $10m tiers, final-law mechanics, in proportion to the balance in each band.

$138,000 additional tax

The rules behind these calculators are written up one by one, worked example first, statute cited, in SMSF rules, as arithmetic.
