Florida small business owners who own commercial or residential rental property sit at the intersection of business taxation and real estate tax law. Depreciation, property expense deductions, cost segregation, and the passive activity rules all interact to create both opportunities and constraints. Florida's no-state-income-tax advantage amplifies the value of federal tax strategies on rental income. Here's the complete picture for 2026.
Residential rental property depreciates over 27.5 years (straight-line); commercial rental property over 39 years. Depreciation creates paper losses that shelter rental income from current federal tax. Example: Florida commercial building (building value $600,000) generates $15,385/year in depreciation ($600,000 ÷ 39). If rent collected is $50,000/year and operating expenses (mortgage interest, taxes, insurance, maintenance) are $35,000, pre-depreciation income is $15,000. After depreciation, taxable rental income is essentially zero — while the property generates positive cash flow. Florida has no state rental income tax.
Health coverage and your tax strategy
Cost segregation studies reclassify components of commercial real estate from 39-year property to 5-, 7-, or 15-year property — dramatically accelerating depreciation in early years. Personal property (carpeting, lighting fixtures, appliances): 5–7 years. Land improvements (parking lots, landscaping, signage): 15 years. A cost segregation study on a $2M Florida commercial building typically reclassifies $400,000–$600,000 of the value into shorter-lived categories, generating $200,000–$400,000 in additional first-year depreciation under bonus depreciation rules. Cost segregation studies cost $5,000–$15,000 but pay for themselves many times over for mid-size commercial properties.
Rental losses are generally 'passive' — they can only offset passive income, not active W-2 wages or business income. Exception 1: $25,000 passive loss allowance — taxpayers who actively participate in rental activities and have AGI under $100,000 can deduct up to $25,000 of rental losses against other income (phases out at $150,000 AGI). Exception 2: Real Estate Professional — taxpayers who spend more than 750 hours per year in real estate activities, and more hours in real estate than in any other profession, can treat rental losses as active (unlimited offset against other income). This status is extremely valuable for high-income Florida business owners with significant rental portfolios.
Short-term rentals (average guest stay under 7 days) may qualify as active business income (not passive rental) if the owner provides significant services. This is a double-edged sword: active income means rental profits are subject to SE tax (15.3%), but losses are active losses deductible against other income. Florida also imposes sales tax (6% + county surtax) on short-term rental income — properties rented for fewer than 6 months at a time are subject to Florida sales and transient rental taxes. County tourist development taxes (1%–6%) also apply. Short-term rental operators must register with Florida DOR and collect/remit these taxes.
Florida is the only state that imposes sales tax on commercial rent. Landlords must collect 6% + county surtax on commercial lease payments and remit to the DOR monthly. This is the landlord's obligation — it must be charged to tenants and separately stated in the lease. Commercial tenants should ensure their lease explicitly identifies the tax separately. For a tenant paying $5,000/month in rent, the sales tax adds $300–$430/month. This recurring cost is unique to Florida commercial real estate and directly affects rental property economics and tenant negotiations.
