Net rental income is what you keep after you subtract your property expenses from the rent you collect

If you rent out a house, apartment, or other property, net rental income is the money left over once you pay for everything it costs to own and maintain that property. You collect rent from tenants, then subtract mortgage interest, property taxes, insurance, repairs, maintenance, utilities you pay, property management fees, and other costs tied directly to the rental. What remains is your net rental income — the actual profit from the property.

This matters because net rental income is what you report to the IRS on your tax return, not the gross rent you collected. The IRS lets you deduct legitimate property expenses, which can significantly lower your taxable income from rentals. Understanding which expenses count and how to track them helps you know your true profit and prepare accurate tax documents.

Key Takeaways

  • Net rental income equals gross rent collected minus all property-related expenses you actually paid during the year.
  • You can deduct mortgage interest (but not principal), property taxes, insurance, repairs, maintenance, utilities, and property management fees.
  • Depreciation is a non-cash deduction that lowers your taxable rental income even though you did not spend money that year.
  • Capital improvements like a new roof have different tax treatment than repairs and must be depreciated over many years rather than deducted in one year.
  • Tracking expenses throughout the year with receipts and records makes tax time simpler and protects you if the IRS questions your deductions.

Expenses you can subtract from gross rent

The IRS allows you to deduct any expense that is ordinary and necessary to operate your rental property. This includes mortgage interest (though not the principal portion of your payment), property taxes, homeowners insurance, liability insurance, and flood insurance if required. You can also deduct the cost of repairs — fixing a leaky roof, patching drywall, replacing a broken window, or repainting a wall.

Utilities you pay on behalf of tenants count as deductible expenses. If you cover water, gas, electricity, trash, or internet as part of the rental agreement, subtract those bills. Property management fees, if you hire someone to collect rent and handle tenant issues, are fully deductible. Advertising costs to find tenants, legal fees for lease disputes, and accounting fees for tax preparation related to the rental also reduce your net income.

Smaller items add up too: supplies like paint and cleaning materials, pest control services, lawn care, snow removal, and condo or HOA fees all count. Keep receipts and invoices for everything, organized by category and date. Many landlords use a spreadsheet or rental property accounting software to track these throughout the year rather than scrambling to find receipts in December.

The difference between repairs and capital improvements

A repair fixes something that is broken or worn out and returns it to its original condition. You can deduct the full cost in the year you pay for it. Patching a roof leak, replacing broken windows, repainting interior walls, fixing a furnace, or replacing damaged flooring are repairs.

A capital improvement adds value to the property, extends its useful life, or adapts it to a new use. Examples include a new roof (not a patch), a new HVAC system, adding a room, installing new plumbing, or upgrading electrical wiring. You cannot deduct the full cost in one year. Instead, you depreciate it — you deduct a portion of the cost each year over many years (typically 27.5 years for residential rental property). This is a slower deduction, but it still lowers your taxable income over time.

The line between the two can be fuzzy. If you replace one shingle, that is a repair. If you replace the entire roof, that is a capital improvement. If you patch drywall, that is a repair. If you renovate an entire room, that is likely a capital improvement. When you are unsure, a tax professional or accountant familiar with rental properties can advise you on how the IRS would treat a specific expense.

How depreciation works in rental income calculations

Depreciation is a deduction for the wear and tear on your building and its systems over time. You do not write a check for depreciation — it is a non-cash deduction that the IRS allows to account for the fact that buildings age and lose value. For residential rental property, you depreciate the building itself (not the land) over 27.5 years.

To calculate depreciation, you need the purchase price of the property, the portion of that price that was the building (not the land), and the date you placed it in service as a rental. A tax professional or depreciation schedule can walk you through this. The annual depreciation amount is the same each year, and you claim it on Schedule E (the IRS form for rental income and loss).

Depreciation lowers your taxable rental income in the years you own the property. However, when you sell the property, the IRS recaptures the depreciation you claimed — you pay tax on it at that time. This is called depreciation recapture. It does not eliminate the benefit of the deduction, but it is important to understand that the tax is deferred, not erased.

Calculating net rental income step by step

Start with the total rent you collected from tenants during the year. This is your gross rental income. If a tenant paid late or you forgave part of the rent, only count what you actually received. If you collected a security deposit, do not count it as income — it belongs to the tenant unless you keep it for damages.

Next, list every expense you paid related to the property: mortgage interest, property taxes, insurance, repairs, maintenance, utilities, property management fees, advertising, legal and accounting fees, and any other ordinary costs. Add them all up. Then subtract the total expenses from your gross rental income. The result is your net rental income before depreciation.

Finally, subtract your annual depreciation amount. This gives you your taxable net rental income — the figure you report to the IRS. If your expenses and depreciation exceed your rent collected, you have a rental loss, which may offset other income on your tax return (subject to passive loss limitations). Keep detailed records of every number you use in this calculation, because the IRS may ask to see them.

Why net rental income matters for taxes and financial planning

The IRS requires you to report rental income on your personal tax return using Schedule E. You must report your gross rent and your deductible expenses, and the IRS calculates your net rental income from there. If you underreport income or claim expenses you did not actually pay, you risk an audit and penalties. Accurate records protect you.

Net rental income also affects other parts of your taxes. If you have a rental loss, it may reduce your taxable income from your job or other sources — but only up to certain limits. High-income taxpayers face passive loss limitations that prevent them from using rental losses to offset other income. A tax professional can explain how your specific situation works.

For financial planning, knowing your true net rental income tells you whether the property is actually profitable. A property that collects $24,000 in annual rent might have $20,000 in expenses, leaving only $4,000 in net income — a 17 percent return on rent collected. Understanding this helps you decide whether to keep the property, refinance it, or sell it.

Common expenses landlords forget to deduct

Many landlords miss deductions because they do not realize the expense counts. If you travel to the property to handle maintenance or meet with contractors, you can deduct mileage at the IRS rate (which changes yearly). If you use part of your home as an office to manage the rental, you may deduct a portion of your home office expenses. Professional fees — accountants, lawyers, property managers — are all deductible.

Tenant screening costs, background checks, and credit reports count. Eviction costs and court fees are deductible. If you provide furniture or appliances as part of the rental, the cost of those items can be depreciated. Pest control, landscaping, snow removal, and trash service are deductible. Homeowners association fees for condos or townhouses are deductible. Many landlords also forget to deduct bank fees for rental accounts or interest on loans taken out to improve the property.

The key is that the expense must be ordinary and necessary to operate the rental. Personal expenses — your own meals, your car payment, your home internet if you use it partly for personal reasons — are not deductible. When in doubt, ask a tax professional or check IRS Publication 527, which covers rental income and expenses in detail.

Frequently Asked Questions

Can I deduct the principal portion of my mortgage payment?

No. Only the interest portion of your mortgage payment is deductible. The principal is a return of your own money and does not reduce your taxable income. Your mortgage statement or lender should show you how much of each payment goes to interest versus principal. In the early years of a mortgage, most of the payment is interest, so the deduction is larger.

What if I have negative net rental income — a loss?

If your expenses exceed your rent, you have a rental loss. You can use this loss to reduce your taxable income from other sources, but there are limits. The IRS passive loss rules prevent high-income taxpayers from using rental losses to offset wages or business income. If you actively manage the property (not just own it), you may be able to deduct up to $25,000 in losses per year if your income is below certain thresholds. A tax professional can explain your specific situation.

Do I need to track expenses if I use a property manager?

Yes. Even if a property manager collects rent and pays bills, you are responsible for reporting accurate income and expenses to the IRS. Ask your property manager for a detailed accounting of all rent collected and all expenses paid on your behalf. Keep copies of invoices, receipts, and bank statements. You are ultimately liable for the accuracy of your tax return.

Can I deduct a loss on a property I just bought?

You can deduct losses from the year you place the property in service as a rental. If you bought it in December and rented it out, you deduct expenses from December forward. If you bought it but did not rent it out until the next year, you start deducting expenses in the year you actually began renting it. The property must be held for the production of income to may have access to.

What records should I keep?

Keep receipts, invoices, and bank statements for every expense you deduct. Organize them by category and date. Keep records of rent collected — lease agreements, cancelled checks, or bank deposits. If you claim depreciation, keep the original purchase documents and the depreciation schedule. The IRS generally has three years to audit your return, so keep records for at least that long, though seven years is safer for rental properties.
