Hi and welcome to Just Answer!If you are roommates - and each pay his.her share of common expenses - there is no rental income for you - and nothing is reported on your tax return. Based on your information - you as a responsible person combine yours and your roommate's expenses in order to make payments to the landlord.If you have a separate sub rent agreement - and collect rental income - the situation would be different - and such income would need to be reported along with rental expenses.If your roommate pays separately for the storage unit which is used solely by you - that would be considered as your income.
I realized that I said I don't collect it but I do. I get the Lot rent statement, divide it by 2 and ask him to give me a check in my name for that amount. I then write a check to the Landlord myself for the Lot rent. But I figured since we are splitting it 50/50 that it was ok and I guess by your answer it is. There is no sub lease agreement. But I am the one renting the Storage Unit, its in my name only. I pay the rent for that storage unit. I am asking my roommate to pay 1/2 of that storage unit rent. by your answer I guess I'd have to report that as rental income. Since I am renting at much lower then 'what normally someone would rent at' I assume just on line 21 of the return?
If the storage unit is rented by you only under a separate agreement - but is paid partially by another person - we need to identify the reason you are paid. Based on your information - that is a part of sublease payment and that person pays you because he/she is your roommate.If that is correct - you must include the full payment and deduct the amount you pay to the landlord for the part you subleased (not used by you personally). It will be reported on schedule E and net income will be reported on form 1040 line 17.
