What gets checked
Sole traders and side income
If you earn income outside a salary, the review covers more ground and you have longer to act.
Sole traders and small businesses get four years from the 2024-25 income year to amend, not two. Home office, vehicle, equipment, insurance, subscriptions and the cost of running the business all come into it.
A registered tax agent goes through this area of your return, line by line, at no cost to you.
A longer amendment window and a wider set of claims. Where something looks incomplete, the agent asks you about it, tells you what evidence would support the claim and only then works out whether an amendment is worth lodging.
If it is, you get the proposed position and the exact fee in writing. If it is not, you have paid nothing and you know the return was right.
