Are Hot Tub Expenses Deductible for My Airbnb?

No credit card required

Yes — hot tub expenses are deductible for Airbnb and STR hosts when the hot tub is used exclusively (or primarily) for guests. The purchase cost qualifies for Section 179 immediate expensing or 5-year MACRS depreciation under IRC §179 and §162(a); ongoing maintenance, chemicals, and service contracts are fully deductible as operating expenses. If you personally use the hot tub as well, you must allocate the deduction based on business versus personal use days.

Why a Hot Tub Qualifies as a Business Deduction

A hot tub installed at an STR property is an amenity that directly supports guest bookings and revenue. Under IRC §162(a), taxpayers may deduct all ordinary and necessary expenses in carrying on a trade or business. A hot tub that attracts bookings and justifies premium nightly rates meets both tests: it is ordinary for STR properties in competitive markets, and it is necessary in the sense that it directly generates income.

The IRS has consistently held that equipment used in rental activity is depreciable business property. A hot tub is classified as 5-year MACRS property when it serves a business purpose — the same category as appliances, furniture, and other personal property used in a rental.

The Revenue Case for Hot Tubs

Data from STR platforms consistently shows that properties with hot tubs command 15–25% higher nightly rates and achieve higher occupancy, particularly in cooler climates and mountain destinations. A $6,000 hot tub with a $1,200 annual maintenance budget isn't just a luxury — it's a revenue driver, and the IRS treats it accordingly.

Installation Costs: Section 179 vs. Depreciation

Hot Tub Purchase + Installation (Section 179)

Form 4562, Part I

Under IRC §179, you can expense the full cost of the hot tub — including purchase price and installation labor — in the year it is placed in service. The 2026 Section 179 limit is $1,220,000, so virtually any hot tub qualifies. This front-loads your deduction and reduces taxable income immediately.

Example: Hot tub purchase ($5,200) + installation ($800) = $6,000. With Section 179, the full $6,000 is deductible in Year 1.

Standard 5-Year MACRS Depreciation

Form 4562, Part II

Without a Section 179 election, a $6,000 hot tub depreciates over 5 years using the half-year convention. Year 1 yields roughly $1,200; the balance spreads through year 6. This is the default if you do not elect Section 179.

Example: $6,000 hot tub → ~$1,200/year deduction across 5+ tax years under MACRS.

Ongoing Maintenance: Fully Deductible as Operating Expenses

Beyond the initial purchase, hot tubs generate recurring maintenance costs that are deductible every year as ordinary operating expenses under IRC §162(a). These go on IRS Line 27a (Other expenses):

Chemicals: Chlorine, bromine, pH balancers, shock treatments, clarifiers
Water testing supplies: Test strips, digital testers, testing kits
Filter replacements: Cartridge filters, filter cleaning solution
Service contracts: Monthly or annual maintenance contracts with a hot tub service company
Cover and cover lifter: Replacement covers, UV-damaged cover repairs, cover lifter hardware
Jets and plumbing repairs: Jet replacements, pump repairs, heater element replacements
Winterization: Annual draining, antifreeze, professional winterization service
Electricity: Hot tub electricity costs (allocate if on shared meter with the property)

Pro Tip

Set up a recurring expense entry for your hot tub chemicals and service contracts in your bookkeeping system. These small recurring costs — $50–$150/month — add up to $600–$1,800/year in deductible expenses that hosts routinely forget to track. Use a dedicated business card for all maintenance purchases.

Mixed Use: When You Also Use the Hot Tub Personally

Here is where the analysis gets nuanced. If the hot tub is at a property where you (the owner) also stay personally — a vacation cabin you rent out part of the year, for instance — you must allocate expenses between business and personal use.

The standard allocation method for mixed-use STR properties uses the following formula:

Mixed-Use Allocation Formula

Rental Days ÷ Total Use Days

Calculate the percentage of days the property (and hot tub) was used for rentals versus personal use. Apply that percentage to all hot tub costs.

Example: Property rented 200 days, personal use 30 days = 230 total use days. Business use = 200/230 = 87%. A $600 annual chemical bill → $522 deductible; $78 personal (non-deductible).

Personal Use Days Warning

Under the IRC §280A vacation home rules, if personal use exceeds 14 days or 10% of rental days (whichever is greater), your rental deductions may be limited to your rental income. Hot tub costs follow the same allocation rules as all other property expenses. Track your personal use days meticulously.

Dedicated STR Property: 100% Deductible

If the property is a dedicated STR that you never use personally — you do not sleep there, use the hot tub, or allow family members to use it for free — then 100% of all hot tub costs are deductible with no allocation required. This is the simplest scenario and the most tax-favorable.

Many STR investors specifically choose to keep dedicated rental properties completely separate from their personal use precisely to preserve full deductibility of all amenity costs.

What About a Hot Tub at Your Primary Residence?

If you rent out a room or a portion of your primary residence on Airbnb, a hot tub in the shared backyard must be allocated based on the percentage of your home used for rental purposes. This is more complex and should be discussed with a CPA familiar with IRC §280A mixed-use dwelling rules.

Frequently Asked Questions

Can I deduct a hot tub on my Airbnb taxes?

Yes. A hot tub used exclusively for Airbnb guests is deductible under IRC §162(a) as an ordinary and necessary business expense. You can depreciate it over 5 years using MACRS or expense it immediately under IRC §179. If you also use it personally, you must allocate the deduction based on business vs. personal use days.

Are hot tub chemicals and maintenance deductible?

Yes. Ongoing hot tub maintenance costs — chemicals, water testing supplies, service contracts, filter replacements, and cover repairs — are fully deductible as operating expenses under IRC §162(a). These go on IRS Line 27a as Other expenses.

What if I use the hot tub personally as well as for guests?

If you use the hot tub personally, you must allocate expenses between business and personal use. A common method is to allocate based on rental days vs. total days of use. Only the business-use percentage is deductible. Exclusive guest use — no personal use by the owner — allows 100% deductibility.

Where do I deduct hot tub installation on your tax return?

A hot tub is a depreciable asset. Claim it on Form 4562. If using Section 179, it goes in Part I of Form 4562 and flows to your tax return. Installation costs are typically capitalized as part of the asset cost. Ongoing maintenance and chemicals go on IRS Line 27a.
