If some of your expenses are shared between personal and business use, you can still claim these expenses, but you are only allowed to claim the portion of your costs relating to business use. Estimating this can be tricky, so we have written a blog post about categorising your side business expenses here.
Once you have split your expenses between personal and business use, you will need to log them in the Earnr app. You can do so by creating a manual transaction for the part of the transaction relating to your side business.
In the app, navigate to the 'Transactions' tab
Tap on the 'Add transactions' button at the top of the page
Select 'Manually add a transaction'
Enter the transaction details, adding only the part of the transaction relating to your side business under 'Amount'.
You can also split your expenses in the app to split any side business expenses you have classified.
