Hi there, @yatsz.
Reimbursement for van hire shouldn't indeed be counted as taxable income. However, we can't directly recommend a specific account for categorizing it, as the categorization will depend on your business's processes or setup.
To help you, you can refer to this article for guidance on how to categorize these types of transactions: Schedule C and Expense Categories in QuickBooks Solopreneur and QuickBooks Self-Employed. Please note that this article is U.S.-based and specific to the QuickBooks Self-Employed product, but the same principles apply to your situation.
It's also a good idea to consult your accountant regarding categorization, especially for complex transactions like this. They can help ensure that you correctly identify the appropriate account for the transaction, which will help avoid mistakes in your financial records and ensure tax compliance.
Let me know if you have any additional questions.
