We subleased half our office after downsizing. How should we separate rent income and lease costs?
Subleasing Unused Office Space: Business Records. A specific owner scenario, the facts that change the answer, and the records needed for a tax review.

Track the sublease receipts and related costs separately, then determine proper reporting and allocations. Passing rent money to the head landlord does not automatically make the subtenant's payment disappear from the books.
A specific business-owner situation
A company retains its full office lease but sublets half the space after downsizing. The subtenant pays a share of utilities and rent. The business needs a clear record of receipts, allocated costs and continuing obligations.
Illustrative example, not a client result.
What to establish before filing
- Confirm subletting authority and terms with counsel.
- Separate sublease receipts from company operating sales.
- Allocate supported shared costs and track deposits.
Which fact changes the answer?
A refundable subtenant deposit differs from prepaid rent or a utility reimbursement. Read the actual terms and retain those balances separately rather than applying one netting policy to every receipt.
A mistake to avoid
Netting subtenant cash directly against rent can obscure gross receipts, deposits and amounts the business still owes.
Records that support the decision
- Head lease.
- Sublease.
- Space and utility allocation.
- Payment and deposit records.
The decision to document
Request a sublease accounting and tax schedule. Reconcile it monthly so ending the sublease does not leave unidentified deposits or unpaid utilities in the operating accounts.
