Rental Bookkeeping 101: How to Track Income and Expenses

Separate the money first

Open one operating checking account per entity, one reserve savings account, and one card used only for property expenses. Mixed personal and rental transactions are the single largest cause of missed deductions, because reconstructing them in March means guessing. A dedicated account is the practical dividing line even when you own in your own name.

• Operating account: rent in, mortgage, taxes, insurance, and vendors out.
• Reserve account: monthly capital reserve transfer, never touched for operations.
• Security deposit account: held separately and never commingled.

Match categories to Schedule E

Use the IRS Schedule E expense lines as your category names: advertising, auto and travel, cleaning and maintenance, commissions, insurance, legal and professional fees, management fees, mortgage interest, repairs, supplies, taxes, utilities, and depreciation. When your categories match the form, tax prep becomes a copy exercise instead of a reclassification project.

Run a 30-minute monthly close

On the first business day of each month, reconcile every account, confirm rent received against the rent roll, verify no personal charges landed on the property card, file receipts by month, and update the reserve balance. Record occupancy, delinquency, and the month-end reserve balance so you have twelve real data points at year end instead of one panicked reconstruction.
