Self-Storage Deductions: The Building and the Cost Segregation, the Gates and the Paving, the Tenant Insurance Commission, the Lien Sale, the Boxes and Locks Florida Taxes, and the Rent It No Longer Does

A self-storage facility is real estate with a service business running on top of it — a building depreciated over decades, surrounded by gates, fencing, paving, cameras, and lighting that depreciate much faster, and an office that sells boxes, locks, and tenant insurance. The deductions follow the components; the income includes rent, fees, commissions, and the occasional lien sale; and since October 2025 Florida no longer taxes the rent itself.

The building and the cost segregation study

The storage buildings are nonresidential real property, depreciated over 39 years. A cost segregation study separates the components with shorter lives: perimeter fencing, gates and access control, paving and drainage, exterior lighting, signage, landscaping, security cameras, and the office's furnishings — 5-, 7-, and 15-year property eligible for 100 percent bonus depreciation when acquired after January 19, 2025. On a newly built or newly purchased facility the study can move 20 to 35 percent of the cost into those classes, producing a large first-year deduction. Climate-controlled units' HVAC is a building system, treated under the improvement rules.

Gates, software, and the office

Access control systems, management software, online rental platforms, cameras, intercoms, and the office's computers are equipment or subscriptions; payment processing fees are deducted from gross. Golf carts and maintenance equipment are equipment. The resident or site manager is an employee, with any on-site apartment a fringe benefit under the lodging-on-premises rules.

Income beyond rent

| Source | Treatment | |---|---| | Unit rent | Rental income from real property | | Late fees, lock-cut fees, administrative fees | Income | | Tenant insurance or protection plan commissions | Income; a facility that sells its own protection plan has service income | | Truck rental commissions | Income | | Lien sales of abandoned units | Proceeds are income; the unpaid rent written off is not a deduction for a cash-method owner that never reported it | | Retail: boxes, tape, locks, packing supplies | Taxable sales; inventory deducted as sold |

Florida sales tax: the rent and the retail

Florida taxed rentals of commercial real property, including self-storage units, until the tax was repealed effective October 1, 2025. For rental periods beginning on or after that date, unit rent carries no state sales tax or county surtax. Retail sales of boxes and locks remain taxable, and the facility registers for that line. Tenant insurance sold as an agent for an insurer follows the insurer's rules; a facility's own protection plan is a service. Vehicle, RV, and boat storage spaces are different: rentals of parking or storage spaces for motor vehicles and of docking or storage spaces for boats were excluded from the repeal and generally remain taxable at 6 percent plus any county surtax.

Rental trade or business, and the deduction

A self-storage facility is a rental real estate business for the passive loss rules — losses are passive unless the owner is a real estate professional or meets an exception — and for the qualified business income deduction it generally qualifies as a trade or business because the facility provides substantial services: an office, a manager, security, retail, and tenant turnover. At higher incomes the deduction is capped at the greater of 50 percent of the facility's W-2 wages or 25 percent of those wages plus 2.5 percent of the unadjusted basis immediately after acquisition of its depreciable property — the building and its components, not the land — which for a facility is large.

Insurance, taxes, and the rest

Property insurance, liability, and workers' compensation for the staff are deductible. Property taxes and the tangible personal property tax on equipment are deductible. Marketing — online listings, signage, the website — is advertising.

Worked example. An owner buys a 400-unit facility for $6.2 million: $900,000 to land (not depreciable), $5.3 million to buildings and improvements. A cost segregation study reclassifies $1.45 million into 5-, 7-, and 15-year property — gates, fencing, paving, lighting, cameras, office — deducted in full under bonus depreciation in year one. Rent of $1.1 million carries no Florida sales tax after October 2025; retail sales of $38,000 are taxable. Tenant insurance commissions add $42,000, late fees $31,000, and four lien sales $6,800. Two site staff are on payroll. The owner, who also holds other rentals, treats the facility as a trade or business for the qualified business income deduction; the year-one bonus depreciation likely produces a loss that reduces the qualified business income from the owner's other businesses (any net loss carries forward), and from year two the deduction's limits are met through the facility's wages and building basis.

The IRS explains: “The underlying incentive for preparing these studies for Federal income tax purposes is the significant tax benefits derived from using shorter recovery periods and accelerated depreciation methods (including bonus depreciation pursuant to IRC § 168(k) and § 179 deductions) for computing depreciation deductions.” — Internal Revenue Service, Publication 5653, Cost Segregation Audit Technique Guide, https://www.irs.gov/pub/irs-pdf/p5653.pdf

The Department of Revenue explains: “This means no state sales tax or discretionary sales surtax applies to rent or license fees for rental or occupancy periods beginning on or after October 1, 2025. Examples of commercial rentals subject to the repeal include rentals of commercial office or retail space, warehouses, and self-storage units.” — Florida Department of Revenue, Tax Information Publication 25A01-04, Sales Tax on Commercial Rentals Repealed Effective October 1, 2025, https://floridarevenue.com/taxes/tips/Documents/TIP_25A01-04.pdf
