The envelope arrives. Or the email. Or the text from your accountant saying the ATO has been in touch about the 2022 return. Suddenly something signed off three years ago is back, with questions, and the response window is short.
You ring your accountant. They say they will look at it. A week later, a half-answer comes back with a quote for the work. Maybe they handle the matter, maybe they refer you out. Either way, it is now expensive, stressful, and on the clock.
ATO matters resolve faster, with much less penalty exposure, when the responder has done it before. Audit work is the same technical work as preparing a return, just in reverse, under deadline pressure, with the ATO on the other side. Trinity has handled hundreds over twenty-three years; the work is repetitive, and the experience compounds.
