How do I know if my rental income qualifies as business income?
If you own one or more rental property and received rent from your tenants on a regular, consistent basis, your rental income qualifies as business income.
Example: You own a house in Cleveland and rented it out to a family all year. The family paid rent on a monthly basis throughout 2016. This qualifies as business income because you received consistent monthly payments.
If you own a house and rented it out temporarily for a short period of time, your rental income doesn't qualify as business income.
Example: You live at Muirfield Village in Dublin, Ohio and rent out your house for two weeks during the Memorial Golf Tournament. Your rental income doesn't qualify as business income because it you didn't receive regular, consistent payments throughout the year.
