Rental Income vs Expenses: How Landlords Make (or Lose) Money

Rental income is the rent you collect from tenants. Expenses are everything you pay out—mortgage, insurance, utilities, repairs, and more. When income is greater than expenses, you have positive cash flow; when expenses are greater, you're losing money. Tracking both is how you know where you stand—and it's what you need at tax time.

What Counts as Rental Income?

Most of your income is rent—the monthly amount your tenant pays. You may also have income from application fees, late fees, or pet rent, depending on your lease and state rules. For tax purposes, all of it is generally taxable unless a specific exception applies. If you're just starting out, see What Is a Rental Property? and What Does a Landlord Do? for the big picture.

What Counts as Expenses?

Expenses are the costs of owning and operating the rental. Common ones: mortgage interest (not principal), property tax, insurance, utilities (if you pay them), repairs and maintenance, property management fees, advertising, and legal or professional fees. Keeping a clear list helps you deduct the right things at tax time. For what to save and how long, read What Records to Keep as a Landlord.

Cash Flow and Profit

Cash flow is the money left over after you pay expenses from rental income in a given period (e.g. each month). Positive cash flow means you have money left; negative means you're paying out more than you take in. Profit (for tax purposes) is your rental income minus allowable expenses over the year—so you can have positive cash flow but still show a loss for taxes (e.g. after depreciation). Both numbers matter: cash flow for your wallet, profit for your return.

Why Tracking Every Dollar Matters for Taxes

The IRS expects you to report all rental income and only deduct expenses you can document. For official guidance, see the IRS topic on rental income and expenses. If you track income and expenses as you go, you're ready when tax season comes—and you don't miss deductions or overstate income. You can do this in a spreadsheet or with property management software that tracks rent and expenses automatically. For what reports to run—income and expense by property, P&L, and tax-ready export—see Property Management Accounting: Reports, P&L, and Owner Statements.
