What counts as rental income and what doesn't

Rental income is any money a tenant pays you for the right to live in or use your property. This includes the monthly rent itself, but also late fees, pet fees, parking fees, and utility reimbursements if your lease requires the tenant to pay you back for those costs. Security deposits do not count as income in the year you receive them — they belong to the tenant until you return them or use them to cover damage.

Payments for things outside the lease also count. If a tenant pays you to break the lease early, that money is rental income. If you charge for a lease renewal or for permission to sublet, those are rental income too. Anything the tenant pays you beyond the base rent, as long as it's tied to their occupancy or use of the property, goes into your rental income calculation.

Money you receive that is not rental income includes security deposits you return, loan proceeds if you borrow against the property, and insurance payouts for damage. These are not income because they do not represent money earned from renting the property.

Key Takeaways

  • Rental income includes base rent, late fees, pet fees, parking fees, and utility reimbursements — anything a tenant pays you tied to their occupancy.
  • Security deposits are not income when you receive them, only if you keep part or all of them to cover damage or unpaid rent.
  • To calculate annual rental income, add up all payments received in the calendar year, then subtract any refunded security deposits.
  • Vacancy periods reduce your actual income but do not change how you report what you did receive — report only money that actually came in.
  • Keep records of every payment, including the date, amount, tenant name, and what it was for, because the IRS may ask to see them.

The basic formula for annual rental income

Start with the rent you actually received in the calendar year, not the rent you were owed. If a tenant paid January through November but skipped December, you count only what came in. If you collected a late payment in January that was owed in December of the previous year, it counts in the year you received it.

Add every other payment: late fees, pet fees, parking fees, utility reimbursements, lease-break fees, lease-renewal fees, anything else the tenant paid you. Then subtract any security deposits you returned to tenants during that year. The result is your rental income for the year.

The formula looks like this:

(Monthly rent received + all other tenant payments) − (security deposits returned) = Annual rental income

This is the number you report to the IRS on Schedule E if you file taxes as an individual, or on your business tax return if you operate as an LLC or corporation.

Handling security deposits correctly

A security deposit is money held in trust. When the tenant moves out, you either return it or use it to cover unpaid rent, damage beyond normal wear, or cleaning costs — depending on what your lease and state law allow. Only the portion you keep counts as income, and only in the year you decide to keep it.

If you receive a $1,500 security deposit in March and return $1,500 in August, neither amount is income. If you receive $1,500 and return $1,200 because the tenant left damage, the $300 you kept is income in the year you made that decision. If you return $1,200 but hold $300 pending a dispute, that $300 does not become income until the dispute is resolved and you decide to keep it.

Keep a separate record for each security deposit: the date received, the tenant name, the amount, the date returned or kept, and the reason if you kept any part of it. This protects you if the IRS questions your income figures, and it also protects you if a tenant disputes whether you returned their deposit.

Accounting for vacancies and unpaid rent

Months when the unit sits empty do not reduce your rental income — you straightforward report zero for those months because you received zero. If your lease calls for $1,500 per month and the unit was vacant for two months, you do not subtract $3,000 from your income. You report only the rent you actually collected.

Unpaid rent also does not reduce your income in the year it was owed. If a tenant owes you $1,500 for December but never pays, you do not report that $1,500 as income. You report it only if and when you collect it, or if you write it off as a bad debt on your tax return (which requires specific IRS rules to be followed).

This is called the cash method of accounting, and it is the most common way landlords report rental income. You report money when it comes in, not when it is owed. Some landlords use the accrual method instead, which reports income when it is owed rather than when it is received, but this requires IRS permission and is less common for small landlords.

Recording payments month by month

Create a straightforward record for each property showing the month, the tenant name, the base rent received, any other payments received, and the total for that month. At the end of the year, add up all the months. This becomes your annual rental income before you subtract any refunded security deposits.

Your record does not have to be fancy. A spreadsheet with columns for date, tenant, rent, late fees, pet fees, parking fees, other payments, and notes works fine. A notebook where you write down each payment as it arrives also works. What matters is that you can show the IRS where the number came from if they ask.

If you use accounting software or a property management platform, it usually tracks this for you and can generate a report at year-end. If you collect rent by check or bank transfer, your bank statements also serve as a record of what came in.

Adjustments for properties with multiple units

If you own a duplex, triplex, or apartment building, calculate rental income for each unit separately, then add them together. This makes it easier to track which unit is vacant, which tenant paid late, and which unit generates the most income. It also helps if you sell one unit later — you will have clear records of its income history.

If you rent out part of your home (such as a room or an accessory dwelling unit), the same rules explore. Any money a tenant pays you for that space counts as rental income. If you provide utilities or internet as part of the rent, you do not add those as separate line items — they are already part of the rent amount.

If you own a property with both residential and commercial tenants, separate the income by type. Residential rental income and commercial rental income may be reported on different tax forms, so keeping them apart from the start saves time at tax time.

What to do with your rental income calculation

Once you have your annual rental income total, you use it to calculate your taxable rental profit. From your rental income, you subtract your rental expenses: mortgage interest (not principal), property taxes, insurance, repairs, maintenance, utilities you pay, property management fees, advertising for tenants, and depreciation. The result is your taxable rental income or loss.

You report this on Schedule E (Form 1040) if you file individual taxes, or on the appropriate business tax form if you operate as an LLC, S-corporation, or C-corporation. Your accountant or tax software will guide you through this step, but they need your accurate rental income number to start with.

If you have questions about whether a specific payment counts as rental income, or whether you can deduct a specific expense, a tax professional who works with landlords can review your situation. The IRS also publishes Publication 527 (Residential Rental Property) and Publication 587 (Business Use of Your Home), which cover these rules in detail.

Frequently Asked Questions

Do I count rent a tenant owes me but hasn't paid yet?

No. Using the cash method (which most landlords use), you report rent only when you actually receive it. If a tenant owes you $1,500 for December but pays in January, you count it in January's income, not December's. If they never pay, you do not report it as income unless you later collect it or formally write it off as a bad debt.

What if I collect rent in advance for next year?

Money you collect in advance is still income in the year you receive it, not the year it covers. If a tenant pays you $3,000 in December to cover January, February, and March of next year, that $3,000 is income in December. This is true even though the tenant has not yet occupied the space for those months.

Can I deduct the mortgage payment from my rental income?

No. You deduct only the interest portion of your mortgage payment, not the principal. Principal is a return of your own money, not an expense of renting the property. Your mortgage statement or lender can tell you how much of each payment is interest versus principal. You also cannot deduct property taxes or insurance from your rental income — these are separate deductions.

How do I handle rent paid in cryptocurrency or other non-cash forms?

You report the fair market value of what you received on the day you received it. If a tenant pays you in cryptocurrency worth $1,500 on the day of payment, you report $1,500 as rental income. If they pay you in goods or services, you report the fair market value of those goods or services. Keep a record of what was paid, when, and what its value was on that date.

Do I need to report rental income if I only rented the property for part of the year?

Yes. Report all rental income you received, even if you owned the property for only a few months. If you bought a rental property in June and collected rent from June through December, you report that income. If you sold a rental property in September, you report the rent collected through September. The number of months does not matter — report what you actually received.
