This depends on the address of your business. If the address where the staff are located, is where the business trades from, that address will be the business place of work. If you travel to that address, the cost would not be an allowable deduction for tax purposes as it would count as simply travel from your home to your place of work. This applies even if you do some work from home.
If, however, your home is the business address then travel to your staff would be allowable.
Structuring your travel costs tax efficiently can be tricky. So feel free to contact your local TaxAssist Accountant if you would like some advice regarding this or any other tax or accounting issue.
