Key Takeaways

• Rental income includes more than just monthly rent — advance rent, security deposits applied to final rent, and payments for canceling a lease are all reportable in the year received.
• Most ordinary and necessary expenses related to the rental activity are deductible, but the distinction between repairs (currently deductible) and improvements (capitalized and depreciated) is one of the most important and most commonly misapplied rules.
• Depreciation on residential rental property uses a 27.5-year straight-line recovery period, and it begins when the property is placed in service — not when the first tenant moves in.
• Personal use of a rental property changes the tax treatment significantly, and properties used for both personal and rental purposes must allocate expenses between the two uses.

Common Mistakes to Avoid

• Treating a major improvement (such as a new roof or kitchen renovation) as a current-year repair expense instead of capitalizing and depreciating it.
• Failing to begin depreciation in the year the property is placed in service, which results in under-claiming depreciation in early years and a messy catch-up later.
• Ignoring the personal use rules for vacation or mixed-use properties, which can limit or eliminate rental deductions.
• Not reporting rental income from short-term rentals or Airbnb-style platforms, which the IRS actively tracks through Form 1099-K reporting.

Section-by-Section Summary

What counts as rental income and why the definition is broader than monthly rent

Publication 527 explains that rental income includes all payments received for the use or occupation of property. This goes beyond monthly rent to include advance rent (taxable in the year received regardless of the period it covers), lease cancellation payments, and expenses paid by the tenant that are the landlord’s obligation. If a tenant pays for a repair that the landlord would normally handle, that payment is income to the landlord and a deductible expense. The publication walks through several examples to illustrate these rules.

How security deposits and advance rent are classified

Security deposits are not income when received if the landlord plans to return them at the end of the lease. However, if any part of the deposit is kept — to cover damage or final rent — that amount becomes income in the year it is retained. Advance rent, by contrast, is always income in the year received, even if it covers a future period. This timing distinction catches many landlords off guard, especially those who collect first and last month’s rent upfront. Understanding the classification rules prevents both over-reporting and under-reporting. For how rental income fits into the overall return, see our guide on how Form 1040 tax returns work.

Which rental expenses are generally deductible

The publication lists common deductible expenses including mortgage interest, property taxes, insurance, management fees, advertising, utilities (if paid by the landlord), and travel to the rental property for maintenance or management purposes. These are reported on Schedule E. The publication also explains that expenses must be ordinary (common in the rental business) and necessary (appropriate for the activity) to qualify. Expenses related to finding a first tenant before the property is placed in service may need to be treated differently than ongoing operating expenses.

Why repairs and improvements are treated differently

This is one of the most important distinctions in the entire publication. Repairs maintain the property in its current condition and are deductible in the year paid. Improvements add value, prolong the life, or adapt the property to a new use and must be capitalized and depreciated over 27.5 years. Painting a room is a repair; adding a room is an improvement. Fixing a leak is a repair; replacing the entire plumbing system is an improvement. The IRS looks at the nature and scope of the work, and misclassification is one of the most common audit adjustments for rental property owners.

How depreciation changes the taxable result

Depreciation allows the landlord to deduct a portion of the property’s cost each year over a 27.5-year period using the straight-line method under MACRS. The land is not depreciable — only the building and improvements. The publication explains how to determine the depreciable basis (generally cost minus land value), how to calculate the first-year deduction using the mid-month convention, and why depreciation must be claimed even if the property generates a loss. Failing to claim depreciation does not preserve the basis — the IRS adjusts basis for depreciation allowed or allowable, which means unclaimed depreciation still reduces the basis when the property is sold.

How personal use and mixed-use property affect the rules

When a property is used for both personal and rental purposes, the publication explains how to allocate expenses. If personal use exceeds the greater of 14 days or 10% of rental days, the property is treated as a personal residence and rental deductions are limited to rental income (no rental loss can be claimed). If the property is rented for fewer than 15 days during the year, no rental income needs to be reported and no rental expenses can be deducted. These rules are particularly important for vacation homes, second homes, and short-term rental properties.

How Publication 527 works with Publication 925 and Publication 946

Publication 527 covers the income and expense rules specific to residential rental property, but it works in coordination with other publications for loss limitations and depreciation. Publication 925 explains the passive activity loss rules that determine whether a rental loss can be deducted against other income (the $25,000 special allowance for active participants is a key exception). Publication 946 provides detailed depreciation tables and explains MACRS in depth. For landlords who also hold rental property through partnerships, see our guide on how K-1s work.

How landlords should use the publication as a practical operating guide

Publication 527 is best used as a year-round reference rather than just a filing-time resource. Landlords should consult it when acquiring a new property (to establish depreciable basis), when making significant repairs or improvements (to classify the expense correctly), and when considering personal use of a rental property (to understand the allocation rules). The publication’s practical examples make it one of the more accessible IRS publications for non-professionals managing their own rental properties.

How to Use This Publication

Start with the income sections to ensure all rental receipts are properly categorized. Then review the expense sections, paying particular attention to the repair vs. improvement distinction. Set up depreciation correctly from the year the property is placed in service. If the property has any personal use, read the mixed-use rules before claiming deductions.

In practice, Publication 527 is the core reference for individual landlords reporting on Schedule E. It does not cover commercial property or properties held in business entities, but for residential rental properties held directly, it covers nearly every common scenario.
