What gets checked
Working from home
The working from home rules have changed several times in recent years. Many returns still use the old ones.
A rate per hour, a fixed rate, or actual costs. Which method was used, whether the hours were recorded and whether separate items such as a desk or monitor were claimed on top all change the outcome.
A registered tax agent goes through this area of your return, line by line, at no cost to you.
Hours at home, the method used and the rules that have changed more than once. 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.

Which method was used
Fixed rate and actual cost methods produce different figures and need different records.

Hours and records
The reviewer checks what evidence exists for the hours claimed and whether it meets the requirement for that year.

Equipment on top
Some items can be claimed separately from the hourly rate. Some are already included in it. This is the most common mistake.
