You set up the fund years ago, with help from an accountant or a financial planner. The annual return shows up like clockwork. You sign it, you send it back. The fund ticks along.
Then a contribution gets coded incorrectly. A property purchase happens without the right LRBA structure. A pension transition uses a template that does not quite fit your situation. The audit raises a flag. The ATO sends a letter. Suddenly the fund you trusted needs unwinding work that should have been spotted years ago.
SMSFs are a different discipline to small business tax. Same accountant credentials, very different rules. Trinity manages over four hundred funds and the work is its own practice: structure, contribution caps, LRBA compliance, pension phase, audit defence. Done weekly, the patterns become visible. Done occasionally, small mistakes accumulate.
