For rental property owners in Washington, having a solid tax strategy is key to maximizing your annual return.

Washington offers a major advantage: no state income tax. Your rental income is only taxed at the federal level, unlike landlords in states where profits are taxed twice—once by the state and again by the federal government.

This makes your tax situation simpler, but it also means federal deductions become even more important. Knowing which expenses you can deduct will help you lower your taxable income and keep more of what you earn.

This blog post walks through the key tax deductions available to Washington landlords.

Washington rental property tax deduction rules

When you own rental property in the Evergreen State, you have a unique advantage: the state does not impose an income tax. This means your rental income is only taxed at the federal level, unlike landlords in states where rental profits face both federal and state income taxes.

Since there is no state income tax, all of your rental property deductions are claimed on your federal tax return, typically using IRS Schedule E. You won’t need to manage a separate set of state-specific deductions or file a state income tax return for your rental income.

How the B&O tax exemption works for landlords

Another aspect of Washington’s tax structure that benefits landlords is the Business and Occupation (B&O) tax. 

While many businesses in the state are subject to this tax, long-term residential rentals (defined as leases of 30 days or more) are exempt. This exemption means you don’t have to worry about B&O tax filings for your rental properties, making your tax obligations simpler.

But, if you own or are considering a short-term vacation rental in Washington (defined as accommodations rented for less than 30 consecutive days) the tax situation is different. 

Short-term rentals are subject to B&O tax under the retailing classification, as well as state and local sales taxes, lodging taxes, and potentially other local taxes depending on your jurisdiction. 

If you own both long-term and short-term rentals, be sure to keep this distinction in mind.

Property tax deductions and tracking

While you won’t pay state income tax, you are still responsible for paying property taxes to your local city or county. These property taxes are fully deductible on your federal return.

There’s another important advantage for landlords regarding property taxes. While homeowners who itemize deductions on their personal residences face a cap on state and local tax (SALT) deductions—$40,000 for tax year 2025 for taxpayers with modified adjusted gross income (MAGI) at or below $500,000, with the cap phasing down to $10,000 for those with MAGI above $600,000, and increasing by 1% annually through 2029—this cap does not apply to rental properties.

As a landlord, you can deduct the full amount of property taxes you pay on your rental properties as a business expense on Schedule E, regardless of how much you pay. This can result in significant tax savings, especially if you own properties in areas with higher property tax rates like Pierce and Spokane counties.

Additional rental property tax deductions available in Washington

Washington landlords can claim a wide range of federal tax deductions that can lower your taxable rental income. Nearly every expense related to running and maintaining your rental property can be deducted. The key is keeping accurate records throughout the year so you don’t miss out on any savings.

Maximizing deductions with Schedule E

IRS Form 1040, Schedule E, is where you’ll report your rental income and expenses each year. This form acts as a roadmap for the costs you can deduct to reduce your taxes. These deductible expenses include:

• Mortgage interest: The interest portion of your rental property mortgage payments can be written off in full. Unlike your personal home mortgage, there’s no cap on how much interest you can claim for a rental property.
• Other interest: If you use a credit card or take out a loan to pay for rental property expenses, the interest on that debt counts too.
• Property taxes: As we covered earlier, the property taxes you pay on your rental can be claimed in full on Schedule E with no SALT cap restrictions.
• Insurance premiums: Premiums for landlord insurance, liability coverage, flood insurance, and other property-related policies all qualify.
• Property management fees: If you hire a property manager to oversee your rental, their fees are a business expense you can claim.
• Professional and legal services: Fees you pay to accountants, tax preparers, or attorneys for rental property matters can be written off. This includes costs for setting up or maintaining an LLC for your rental business.
• Commissions: Fees paid to real estate agents or leasing agents for finding and placing tenants.
• Cleaning and maintenance: Regular upkeep costs like lawn care, pest control, and cleaning services.
• Repairs: Costs for fixing things that break or wear out like repairing a leaky pipe, patching a hole in the wall, or replacing a broken window can be claimed in the year you pay for them.
• Supplies: Day-to-day items you need to maintain your property, such as light bulbs, air filters, smoke detector batteries, and cleaning supplies.
• Utilities: If you pay for utilities like water, electricity, gas, or trash service for your tenants.
• Travel expenses: Mileage and travel costs when you drive to your rental property for management, maintenance, or rent collection. You can use the IRS standard mileage rate or track actual vehicle expenses.
• Advertising costs: Money spent on marketing your rental, whether it’s online listings, yard signs, or newspaper ads.
• Home office: If you use part of your home exclusively and regularly for managing your rental business, you may be able to claim home office expenses.
• Depreciation: This is often the biggest deduction for landlords. It lets you write off a portion of your property’s value (not including land) over 27.5 years for residential rentals.

Depreciation: Your most valuable deduction

The IRS treats rental properties as assets that wear out over time. For residential rental properties, you can depreciate the building’s value over 27.5 years. It’s important to note that you can only depreciate the structure itself, not the land it sits on. Your property’s purchase price needs to be split between land and building value.

Here’s an example: If you bought a rental property for $400,000, and the land is valued at $100,000, you can depreciate $300,000 over 27.5 years. That works out to roughly $10,909 per year in depreciation deductions, reducing your taxable income without any out-of-pocket expense.

When you make improvements to the property like adding a new deck or renovating a bathroom, those costs also get depreciated over time, increasing your annual deduction. Keeping detailed records of your original purchase price, closing costs, and any improvements you make will ensure you’re claiming the correct depreciation amount each year. 

Repairs vs. improvements: Understanding the difference

One of the most common areas of confusion for landlords is knowing the difference between repairs and improvements. The distinction matters because it affects when and how you can deduct the expense.

Repairs are costs that keep your property in good working condition without adding significant value or extending its useful life. These expenses can be deducted in full in the year you pay for them. Examples include fixing a broken window, patching a leaky roof, repainting a room, or replacing a worn-out appliance with a similar model.

Improvements, on the other hand, add value to your property, extend its useful life, or adapt it to a new use. These costs can’t be deducted immediately. Instead, they’re added to your property’s depreciable value and written off over time, as explained in the depreciation section above. Examples include adding a new room, installing a new roof, upgrading to high-end appliances, or renovating a kitchen.

Sometimes the line between the two can be blurry. For instance, replacing a few damaged shingles is a repair, but replacing the entire roof is an improvement. Repainting a room is a repair, but adding custom built-in shelving is an improvement.
