How easy is it to compare your two activities ?
If your business involves a second type of service, then this category is for you! It will enable you to easily track and compare these two types of income 🕵🏻.
Are you an ophthalmologist (VAT-exempt) who also offers cosmetic procedures (subject to VAT) ? Are you a lawyer offering BAJ services (0% VAT) or acting as a property administrator (VAT exempt) ? In this case, your activity involves services with two different VAT rates. Prefer to use two different categories for your income.
💡 Use the "secondary service" category when you have two types of income in your business. In particular, to distinguish between income with different VAT rates.
