Renting out residential property is considered a source of income, not employment. This income should be declared to the Inland Revenue Department at the end of the year. Since it's not classified as employment activity, you don't need to fill out a self-employed engagement form for this. However, if you consider this property renting as your main source of income for tax and national insurance purposes, then you should submit an "Engagement Form - Self Employed” to Jobsplus.
