What Are the Primary Deductions for LLC Rental Properties?

When you own rental property through an LLC, the IRS permits numerous deductions that directly reduce your taxable rental income. The most valuable deductions fall into two categories: operating expenses and capital cost recovery (depreciation). Understanding which expenses qualify is crucial for maximizing tax efficiency while maintaining audit protection.

Operating expenses are costs incurred to generate rental income during the current tax year. These deductions are available immediately and include property management fees, maintenance and repairs, insurance premiums, utilities, HOA dues, and advertising costs for finding tenants. For 2026, the threshold for distinguishing repairs (deductible) from improvements (capitalized) remains unchanged, making proper documentation essential.

Mortgage interest represents one of the largest deductible expenses for most rental property owners. Unlike mortgage principal payments, which reduce your equity but aren’t tax-deductible, interest payments are fully deductible in 2026. Property taxes also qualify as direct deductions, though they’re subject to the $40,000 SALT cap for 2026 under current rules.

Operating Expenses That Qualify for Deduction

• Mortgage Interest: Fully deductible in 2026; principal payments are not deductible.
• Property Taxes: Deductible but capped at $40,000 annually under 2026 SALT limitations for incomes under $500,000.
• Insurance: Homeowners, liability, and loss-of-rent insurance are fully deductible for rental properties.
• Utilities: If you pay utilities, they’re deductible; if tenants pay, document this arrangement carefully.
• Maintenance and Repairs: Routine repairs that keep property in working condition are deductible; major renovations may require capitalization.
• Property Management Fees: Completely deductible in 2026, whether you hire a company or use software services.
• Professional Services: CPA fees, tax preparation, and accounting services for rental activities are fully deductible.

Home Office and Travel Deductions for LLC Management

If you maintain a dedicated home office exclusively for managing your rental properties, you can deduct a portion of rent, utilities, and office supplies. The IRS allows either actual expense or simplified method ($5 per square foot, maximum 300 square feet). Travel to inspect properties, meet with contractors, or consult with tax professionals is also deductible if properly documented.

Expense Category	2026 Treatment	Documentation Required
Mortgage Interest	Fully Deductible	Form 1098 from lender
Property Taxes	Deductible (SALT capped at $40,000)	Property tax bill and payment receipts
Repairs	Fully Deductible	Invoices and payment records
Improvements	Capitalized (Depreciated)	Detailed capital expenditure records
Insurance	Fully Deductible	Annual insurance statements

How Does Depreciation Work for Rental Properties?

Depreciation is one of the most powerful deductions available to rental property owners. The IRS recognizes that buildings lose value over time and permits you to deduct that estimated loss of value annually. For residential rental property, the depreciable life is 27.5 years under the Modified Accelerated Cost Recovery System (MACRS). This means a property with a $250,000 depreciable building value generates approximately $9,091 in annual depreciation deductions for 2026.

The key distinction in calculating depreciation is separating land value from building value. Land never depreciates for tax purposes because it doesn’t wear out. A professional appraisal or assessment can help establish the initial allocation. For example, if you purchase a rental property for $350,000 with 30% allocated to land and 70% to the building, only the $245,000 building value qualifies for depreciation in 2026.

MACRS Depreciation Methods for Residential Rental Property

The Modified Accelerated Cost Recovery System (MACRS) for residential rental property is relatively straightforward. Under straight-line depreciation for 27.5-year property, you deduct an equal percentage of the depreciable basis each year. The calculation is simple: divide the depreciable basis by 27.5 to get the annual deduction.

For 2026 acquisitions, the first-year depreciation must be adjusted for the month of acquisition. If you purchase a rental property in June 2026, you only deduct depreciation for the remaining seven months of that tax year. The IRS Publication 946 provides detailed depreciation schedules and calculation methods for various property types and acquisition dates.

Land vs. Building Allocation for Maximum Deductions

Maximizing your depreciation deduction starts with properly allocating your purchase price between land and building. The higher the building allocation, the larger your annual depreciation deduction. Several methods can support this allocation: professional property appraisals, assessed property tax values, previous appraisals, insurance valuations, or contractor estimates of construction costs.

For 2026 tax purposes, maintaining documentation of how you determined this allocation is essential. The IRS may challenge aggressive allocations that heavily favor the building component. A reasonable approach is using the ratio of land-to-building values from local property assessments, which typically allocate 20-40% to land depending on location and property type.

What Is Cost Segregation and How Can It Maximize Deductions?

Cost segregation is an advanced tax strategy that can dramatically accelerate your depreciation deductions in 2026. Instead of depreciating the entire property over 27.5 years, a cost segregation study breaks down the property into individual components, many of which qualify for shorter depreciable lives. For example, appliances, flooring, and fixtures may depreciate over 5-7 years instead of 27.5 years, generating significantly larger first-year deductions.

The process involves hiring specialized engineers and tax professionals to conduct a detailed analysis of your property. They identify materials, construction methods, and component costs, then allocate these to the appropriate IRS asset categories. A typical cost segregation study on a $500,000 residential rental property might identify $80,000-$120,000 of costs that can be reclassified to 5-7 year property, creating an additional $15,000-$25,000 in first-year deductions beyond standard depreciation.

Eligible Property Components for Accelerated Depreciation

• Appliances: Typically 5-7 years; includes HVAC systems, water heaters, built-in appliances.
• Flooring: Vinyl, tile, laminate, and carpet depreciate faster than the building structure.
• Fixtures: Light fixtures, plumbing fixtures, and built-in cabinets qualify for accelerated schedules.
• Landscaping and Site Improvements: Paving, fencing, and drainage systems often qualify for 15-year property.
• Sidewalks and Exterior Elements: Many exterior improvements qualify for shorter depreciable lives than the main structure.

The cost of a comprehensive cost segregation study typically ranges from $3,000-$8,000 depending on property size and complexity. For a property generating $20,000+ in accelerated deductions, this represents an excellent return on investment. The IRS permits cost segregation retroactively, meaning you can claim it for properties purchased in 2024-2025 when you file 2026 returns.

Bonus Depreciation and Section 179 Considerations for 2026

In 2026, certain property components may qualify for bonus depreciation or Section 179 expensing, allowing immediate deductions rather than spreading them over years. While primary residential buildings don’t qualify for bonus depreciation, certain property improvements and equipment may. Consulting with a professional tax strategy advisor ensures you’re capturing every available 2026 deduction opportunity.

How Do Passive Activity Rules Affect Your Deductions?

One of the most significant limitations on rental property deductions is the passive activity loss rule. Unless you meet specific criteria, the IRS limits your ability to deduct rental losses against wages or business income from other sources. For 2026, if you’re not considered a real estate professional, you can deduct a maximum of $25,000 in rental losses annually, with this allowance phasing out for taxpayers with modified adjusted gross income (MAGI) between $100,000-$150,000.

This limitation exists because the IRS considers rental real estate to be a passive activity—you’re not actively involved in day-to-day operations. However, there are important exceptions and strategies available for 2026. Understanding whether you qualify as a real estate professional is crucial, as this designation eliminates passive activity loss limitations entirely.

Qualifying as a Real Estate Professional in 2026

To qualify as a real estate professional for 2026 tax purposes, you must meet two strict IRS requirements. First, more than half of your personal services during the tax year must be performed in real property trade or business activities. Second, you must materially participate in such activities by performing more than 750 hours of work during the year. These hours include time spent managing, maintaining, and improving rental properties.

The 750-hour threshold is often achievable for full-time real estate investors. To document this qualification, maintain detailed time records showing hours spent on property inspections, tenant communications, maintenance coordination, accounting, and strategic planning. Simply owning properties isn’t sufficient; you must actively participate in their operation.

If you qualify as a real estate professional, the passive activity loss rules don’t apply. You can deduct all rental losses against other income, subject only to general loss limitation rules. This can generate significant tax savings for 2026 if your properties produce losses due to large depreciation deductions exceeding actual cash expenses.

Suspended Losses and Carryforward Rules

If you can’t deduct all your rental losses in 2026 due to passive activity limitations, the unused losses aren’t lost permanently. Instead, they’re suspended and carried forward indefinitely, deductible when you have sufficient passive activity income in future years or when you finally sell the property. Upon sale of the rental property, all accumulated suspended losses become deductible in the year of sale.

Taxpayer Status	2026 Loss Limitation	Material Participation Required
Not Real Estate Professional	$25,000 (phases out at higher income)	No (classified as passive)
Real Estate Professional	No passive activity limitation	Yes (750+ hours required)
Active Real Estate Investor	$25,000 (with conditions)	Yes (significant involvement)

What About the 2026 SALT Deduction Cap for Rental Properties?

The SALT deduction cap significantly impacts rental property owners in high-tax states. For 2026, the maximum SALT deduction is $40,000 annually for married couples filing jointly ($20,000 for single filers). This cap combines your deductions for state income taxes, local property taxes, and sales taxes. For rental property owners, this typically means property taxes consumed a substantial portion of the $40,000 allowance.

The SALT cap wasn’t anticipated to expire after 2025, making it a permanent feature of the tax code affecting 2026 planning. Property owners in California, New York, New Jersey, and other high-tax states are significantly impacted. With property taxes ranging from 0.5%-2% of property value annually, owners of properties valued at $1-2 million quickly exhaust the $40,000 cap.

Strategic Planning to Maximize SALT Deduction for Rental Properties

For 2026, several strategies can help maximize your SALT deduction benefit. First, if you have significant mortgage interest and property taxes, consider whether itemizing provides more benefit than the standard deduction ($31,500 for married filing jointly). Second, understand how pass-through entity (PTE) elections in your state can convert individual property taxes into deductible business taxes that escape the $40,000 cap.

In certain states like New York, California, and Illinois, pass-through entity tax elections allow you to elect into a special tax regime where the entity (LLC, S-Corp) pays a state tax on business income. This creates a state tax credit for your owners while potentially preserving their federal SALT deduction beyond the $40,000 cap. The mechanics vary significantly by state, requiring careful planning.

SALT Deduction for Mortgage Interest vs. Property Taxes

An important distinction: mortgage interest on rental properties is NOT subject to the SALT cap. You can deduct all mortgage interest paid on rental property loans regardless of the SALT cap. Only property taxes, state income taxes, and sales taxes count toward the $40,000 limitation for 2026. This makes mortgage interest deductions particularly valuable for high-income rental property owners who exceed the SALT cap.

Can You Claim Qualified Business Income Deduction on Rental Income?

The qualified business income (QBI) deduction, established under the Tax Cuts and Jobs Act and continuing through 2026, allows eligible taxpayers to deduct up to 20% of their qualified business income from pass-through entities. For rental property owners, this creates an additional deduction opportunity beyond traditional depreciation and operating expenses. However, eligibility depends on how your rental activity is structured and operated.

Generally, passive rental income from a simple lease arrangement doesn’t qualify for the QBI deduction in 2026. However, if you provide significant services (arranging repairs, negotiating tenant terms, managing property actively), your rental activity may qualify as a business rather than passive rental activity. Additionally, certain real estate service businesses qualify for the QBI deduction without the same limitations.

Eligibility Requirements and W-2 Wage Limitations for 2026

The QBI deduction for 2026 has income-based limitations and complexity regarding W-2 wages and depreciable property. For taxable income below $364,200 (married filing jointly), the basic QBI deduction of 20% applies. For income above this threshold, limitations based on W-2 wages paid and qualified property basis apply. Many rental activities don’t involve W-2 wages, which can limit the QBI deduction at higher income levels.

For real estate developers, real estate agents, or property managers who actively operate rental businesses, the QBI deduction often applies. The key determination is whether the IRS views your activity as a business versus passive rental. Proper documentation of active involvement, strategic decision-making, and business management strengthens your position for 2026 QBI claiming.

 

Uncle Kam in Action: Real Estate Investor Unlocks $28,500 in Deductions Through Cost Segregation

Client Snapshot: Marcus, a real estate investor managing a portfolio of four residential rental properties across a mid-Atlantic state, consistently reinvested profits into property acquisition. His portfolio generated approximately $145,000 in annual rental income from four multi-unit properties.

Financial Profile: With $1.2 million in total property value, annual rental revenue of $145,000, and significant mortgage debt, Marcus faced substantial tax liability despite property expenses. His modified adjusted gross income was approximately $195,000, putting him above the passive activity loss phase-out threshold.

The Challenge: Marcus was capturing standard depreciation deductions but leaving significant tax savings on the table. His accountant had been using basic MACRS depreciation over 27.5 years for all properties, and his newest acquisition (purchased in 2025) generated only $7,200 in annual depreciation. Additionally, his MAGI exceeded $150,000, completely eliminating his $25,000 passive activity loss allowance. He needed a strategy to convert his properties’ positive cash flow into tax efficiency.

The Uncle Kam Solution: Our team recommended a comprehensive strategy for 2026 combining cost segregation with real estate professional status evaluation. For Marcus’s newest property acquisition of $380,000, we commissioned a cost segregation study that identified $92,000 of components with shorter depreciable lives (5-7 year property). This reclassification generated first-year accelerated depreciation of $16,750 beyond the $8,100 standard depreciation. Simultaneously, we documented Marcus’s time investment in property management activities—inspections, tenant coordination, maintenance oversight, and financial analysis—establishing 920 hours of material participation, qualifying him as a real estate professional for 2026.

This combination eliminated his passive activity loss limitations and maximized his cost segregation benefit. For 2026, his total depreciation deductions increased from an estimated $32,400 (standard depreciation only) to approximately $49,150 (standard plus cost segregation accelerated component).

The Results:

• Tax Savings: $28,500 in additional deductions at his marginal tax rate of 32% generated approximately $9,120 in federal tax savings for 2026, with additional state tax savings of $1,710.
• Investment: The cost segregation study ($4,800) and tax planning consultation ($1,200) represented a total 2026 investment of $6,000.
• Return on Investment (ROI): The $10,830 in combined federal and state tax savings represented a 1.8x return on the $6,000 investment in the first year alone, with the accelerated depreciation benefit extending through 2050.

This is just one example of how our proven tax strategies have helped clients achieve substantial savings and financial success in real estate investing. For Marcus, converting his passive losses into business deductions through professional status and leveraging cost segregation’s accelerated schedules transformed his tax picture entirely. The strategies deployed in 2026 will continue providing benefits across his entire portfolio for decades.

Frequently Asked Questions

Can I Deduct Losses from Rental Properties in 2026?

Yes, but with limitations. If you’re not a real estate professional, you can deduct a maximum of $25,000 in rental losses annually in 2026, provided your modified adjusted gross income doesn’t exceed $100,000. The allowance phases out at higher income levels, reaching zero at $150,000 MAGI. If you qualify as a real estate professional (750+ hours of material participation), passive activity loss limitations don’t apply, and you can deduct all rental losses.

Is Depreciation Recaptured When I Sell My Rental Property?

Yes, depreciation recapture is an important consideration for 2026 planning. When you sell a rental property, all depreciation deductions claimed are recaptured at a 25% tax rate, which is higher than the long-term capital gains rate of 15-20%. This doesn’t eliminate the benefit of depreciation deductions during ownership (you still reduce your taxable income annually), but it’s important to understand this tax cost when planning property sales.

How Do I Know If My Expense Is a Repair or Improvement for 2026?

The distinction is crucial for 2026 deductions. A repair maintains property in its current condition and is immediately deductible. An improvement enhances property value, extends its useful life, or adapts it to a new use, and must be capitalized and depreciated. For example, fixing a leaky roof is a repair; replacing the entire roof structure is an improvement. When expenses exceed $2,500, enhanced recordkeeping and potentially professional guidance from your tax advisor becomes valuable.

Can I Deduct Mortgage Principal Payments on Rental Properties?

No, mortgage principal payments are never tax-deductible. However, the interest portion of your mortgage payment is fully deductible in 2026. In early years of mortgage repayment, interest comprises the majority of your payment. Your lender provides a statement (Form 1098) detailing the interest portion paid annually, which you claim as a deduction on your tax return.

What Documentation Should I Keep for 2026 Rental Property Deductions?

The IRS requires substantiation for all deductions claimed. Maintain a file containing: property purchase documentation and allocation of land vs. building, mortgage statements showing annual interest paid (Form 1098), property tax bills and payment receipts, insurance policy documents and premium receipts, invoices and receipts for all repairs and improvements, contractor and vendor statements, property management records, and documentation of personal time investment if claiming real estate professional status. Keep these records for at least three years (seven years is safer for substantiation).

How Does the SALT Cap Affect My Rental Property Strategy for 2026?

The $40,000 SALT cap in 2026 significantly impacts high-income rental property owners in high-tax states. If your property taxes and state income taxes exceed $40,000, you can’t deduct the excess. To optimize your strategy, focus on maximizing depreciation and mortgage interest deductions (which have no limitations), investigate pass-through entity tax elections in your state, and consider whether bundling multiple years of deductions (SALT and business expenses) makes itemizing versus taking the standard deduction more advantageous.

Should I Conduct a Cost Segregation Study for My Rental Property?

A cost segregation study is worthwhile if your property meets these criteria: (1) significant depreciable basis ($200,000+), (2) recent acquisition or substantial renovation that generates enough accelerated depreciation to offset the study cost ($3,000-$8,000), and (3) sufficient tax liability to benefit from additional depreciation deductions. For most rental property investors with properties valued at $300,000 or more, a cost segregation study generates positive ROI within the first year.

Can I Claim Home Office Deductions Related to Rental Property Management in 2026?

Yes, if you maintain a dedicated home office exclusively for rental property management, 2026 rules permit deductions. You can use the actual expense method (deducting actual utility costs, rent, insurance allocable to the office) or the simplified method ($5 per square foot, maximum 300 square feet). To claim this deduction, the office must be used regularly and exclusively for property management—a desk in the living room doesn’t qualify, but a separate study used entirely for managing your rental business does.
