Rental income is the money that a property owner receives in exchange for letting another person or business use their property. This income includes rental payments received in advance, late payments, and current payments received. In addition to that, money received for lease cancellations and refunded security deposits are also treated as rental payments. Any extra payments from renters for services that a landlord typically offers. For example, cleaning communal areas, hallways, and utility expenses includes hot water, heating, broadband, and water. Making arrangements for the property’s repairs or, if you charge any non-refundable deposits for your property, all these will be considered in your rental income tax in the UK. As will any money that is leftover from a returnable deposit at the end of the tenant’s lease.
