$330 a month for the lease by American Tae Kwon Do and $65 a month from a barber shop would also seem to be unrelated business income, wouldn't it? Add these sums to the Subway lease and you get $895 a month, which would be more than $10,000 a year, or more than 10 times the threshold for filing Form 990-T.
Infraction or discrepancy? Or am I overlooking something somewhere? Or is income from Tae Kwon Do, barber shops, and restaurants related to 3ABN's exempt activities in some way?
