The IRS (Internal Revenue Service) has multiple ways to identify whether you’re earning rental income, even if you don’t report it yourself. From tax documents and property records to online rental listings and payment platforms, the agency uses sophisticated data-matching systems to detect unreported income. Whether you rent out a property full-time, list it occasionally on Airbnb, or receive rent payments directly from tenants, the IRS can track it through various channels.

Understanding how the IRS monitors rental income is essential to stay compliant, avoid penalties, and ensure your taxes are filed correctly. This guide explains the key ways through which the IRS identifies rental income.

What is Rental Income According to the IRS?

According to the IRS, rental income is any payment you receive for the use or occupation of a property. You may deduct the property's expenses from your gross rental income in the year you pay the expenses.

Here's an example: You rent an apartment for $800 per month. In addition, you receive a security deposit from the tenants of $800 and additional fees of $50 per month for maintenance. Expenses related to this property include a mortgage payment of $400 per month, insurance, landscaping fees, and property taxes.

You may deduct the first three expenses from your rental income. For property taxes, you may deduct any property tax paid on the property during a vacancy period. If you also had to repair the furnace for $1,000, you may deduct this expense from your rental income as well.

How Does Rental Income Reporting Work?

Individual taxpayers must report rental income on their return for the year they receive it. That means you'll include rental income on your individual income tax return. While you can deduct appropriate expenses, it's your responsibility to report the rental income.

If you don't, the IRS can get rental income information from routine tax audits, real estate paperwork, public records, and whistleblower information. If you don't report rental income, you could face accuracy-related penalties, civil fraud penalties, or possible criminal charges.

How Does the IRS Track Rental Income?

The IRS tracks rental income from various sources and uses this information to verify your individual income tax return. Not claiming rental income on taxes is a reason to be flagged for an IRS audit, and if you report incorrectly, you'll have to pay fees or other penalties. How does the IRS catch unreported rental income? Common sources of rental income information for the IRS include:

Schedule E on Form 1040

You must report rental income directly to the IRS using Schedule E on Form 1040. The IRS matches data from these forms with other sources, such as landlord reports, third-party reporting services, and real estate information.

Tax Audits

Failure to report income, including rental income, is one of the biggest reasons for a tax audit. During a tax audit, the IRS reviews and examines individual accounts and finances to ensure information is reported correctly according to the tax laws and to verify the reported amount of tax is correct. Of course, this will also turn up any unreported rental income.

IRS Automated Underreporter Program

As the name suggests, this partially automated program matches your tax return against information gathered by the IRS. This extensive information includes returns and schedules that are much more detailed than W-2 and 1099 forms.

Loan or Refinance Applications

Loan or refinance applications are available to the IRS. If you were approved for a loan, this could suggest an additional property purchase that may be used as a rental property.

Property Tax Records

If you own additional properties beyond your primary residence, this will show in property tax records and is available to the IRS. It will compare your individual income tax return with property tax records. If you don't report rental income, this can become a discrepancy.

IRS Whistleblower Office

According to the IRS website, its Whistleblower Office “pays monetary awards to eligible individuals whose information is used by the IRS.” This award varies but can range from 15% to 30% of the proceeds collected based on the whistleblower's information. That is a big incentive for informants to suggest that the IRS check whether you report rental income. If your after-expenses rental income is $2,000 per month, the whistleblower could gain $3,600 to $7,200.

Common Mistakes to Avoid When Reporting Rental Income to the IRS

Ready to ensure you accurately report all rental income to the IRS? The consequences of these mistakes, including fines and penalties, can be avoided with accurate, careful reporting. Here are the most common mistakes taxpayers make when reporting rental income and how to avoid them:

Failing to Report All Income

The most obvious mistake is failing to report all income. You must include fees, deposits, and all other income received related to the rental property. Then, double-check numbers to ensure you didn't miss a zero or accidentally only reported part of the year.

Deducting Expenses that Aren't Allowed

You may only deduct expenses that are exclusively related to renting out your property. You can't add on personal expenses. For example, you may deduct landscaping expenses or repair expenses of the rental property, but you cannot deduct the same expenses for your primary residence.

Failing to Keep Accurate Records

Failing to keep accurate records of rental expenses and income can make filing accurate tax returns difficult. You'll need to go back and gather all the correct information. Otherwise, taxpayers risk filing inaccurate returns and having to pay associated penalties and fees.

Misreporting Depreciation

Taxpayers may file an incorrect basis depreciation and calculate depreciation inaccurately on an annual basis. If you incorrectly report depreciation, you must file Form 3115 to correct the depreciation error and may need the help of a certified public accountant to ensure correct depreciation calculations.

Improperly Designating Personal Use

If you use the rental property for a vacation or other personal use, you cannot deduct any expenses from the time you occupy the property. In addition, according to the IRS, you use a rental property as a private dwelling if you use it for more than 14 days or 10% of the total days you rent it to others at a fair price in a given year. That means if you stay in the rental property for two months each summer, it's considered a private dwelling, and you won't be able to take the same deductions.

Reporting Rental Income Accurately

Rental income can be a powerful additional income stream that can give you financial freedom. Protect yourself and your income by setting up systems to report all income accurately. For those wondering, “Can I get away with not paying tax on rental income?” The answer is a strong no. But you can simplify reporting and management.

It's worth getting an app or tracking software to record all rental income and expenses to stay ahead of reporting rental income. When tax time rolls around, you're prepared. With a little planning, you'll be ready to avoid common rental income reporting mistakes while enjoying long-term financial growth from real estate investments.
