Window Cleaning Deductions: The Water-Fed Pole and the Pure Water System, the Lifts and the Rope Access, the Route, the Residential Jobs Florida Doesn't Tax and the Commercial Jobs It Does

Window cleaning runs from a van with a water-fed pole and a tank of deionized water, or from a swing stage on the side of a tower. The residential side is job by job; the commercial side is a route of storefronts, offices, and buildings on monthly or quarterly contracts. Florida taxes the second and not the first — nonresidential cleaning is a taxable service — so the invoices are split from the start.

Equipment and supplies

| Item | Treatment | |---|---| | Water-fed pole systems, deionization and reverse osmosis units, tanks, pumps | Equipment; Section 179 or bonus depreciation, or the de minimis safe harbor by cost | | Ladders, standoffs, fall protection | Equipment or supplies by cost | | Rope access rigs, descenders, bosun's chairs, swing stages (owned) | Equipment; rentals are an expense | | Squeegees, scrubbers, scrapers, towels, soap, resin for the deionization unit | Supplies, deducted when bought | | Vans and trucks over 6,000 pounds gross vehicle weight | Deducted in full the first year with 100 percent bonus depreciation (property acquired after January 19, 2025) when used more than 50 percent for business; actual-expense method |

Resin replacement for pure water systems and pump repairs are maintenance; a new deionization unit is equipment.

Crews and classification

Technicians who work the company's route in its vans with its equipment are employees — payroll, withholding, unemployment, and workers' compensation at Florida's four-employee threshold for non-construction work — window cleaning is not among the construction classes in Florida's workers' compensation rules. High-rise and rope-access work may be classified differently for workers' compensation and carries training requirements under the safety regulations; the certifications are deductible. Solo cleaners with their own gear who take overflow are contractors, reported on Form 1099-NEC once payments to one reach $2,000 in a year (the threshold for payments made after 2025).

The commercial route

Storefront and office contracts — weekly, monthly, quarterly — are recurring income, billed as serviced or prepaid. Prepaid annual contracts are income when received by a cash-method company. Property management companies that pay the company $2,000 or more in a year issue Forms 1099-NEC — unless the company is a corporation, including an S corporation, since payments to corporations are generally exempt from the form. Route software, scheduling, and invoicing subscriptions are deducted as paid.

Insurance

General liability (the cracked pane, the fall onto a customer's car), commercial auto, inland marine on the equipment, and workers' compensation are deductible. High-rise and rope-access work requires limits and endorsements that building owners specify, and the premium follows the height.

Florida sales tax: commercial is taxable

Nonresidential cleaning services are taxable in Florida, and the Department of Revenue's cleaning rule lists window cleaning, interior or exterior, among its examples — so windows of offices, storefronts, restaurants, and other nonresidential buildings are taxable. Residential window cleaning — a house, an apartment building, a residential condominium unit or tower, and the common areas of those residential buildings — is not taxable. A company that serves both registers, collects on every commercial invoice, and keeps residential invoices separate. Pressure washing is the exception: the same rule says power washing a building's exterior, or a parking lot or garage, is not taxable as a cleaning service. The company itself pays sales tax on the supplies and equipment it buys, because a cleaning service is the consumer of what it uses.

Seasonality and the storm

Residential demand peaks in spring and before the holidays; commercial routes are steady. After a hurricane, salt and debris on glass across a region produce a surge of both. The annualized method on Form 2210 handles the surge; the prior-year safe harbor handles a normal year.

Worked example. A window cleaning company runs three vans with water-fed systems and a two-person rope-access team. It buys a $9,800 pure water system and a $54,000 van, both deducted in full; rope-access gear totals $6,200 (expensed). Its revenue is $420,000 commercial (taxable — collected and remitted) and $140,000 residential (exempt). Seven technicians are on payroll with workers' compensation; the rope-access team's certifications are deducted. Three property management companies issue 1099-NECs. Its high-rise liability endorsement adds $11,000 to the premium.

Florida's sales tax rule on cleaning services provides: “Residential cleaning services are not taxable. Charges for cleaning residential facilities used as living accommodations for persons, such as detached or single family dwellings, apartments, duplexes, triplexes, quadraplexes, residential condominiums, residential cooperatives, residential time-share units, beach cottages, nursing homes, and mobile home parks, and the common areas of those residential facilities, are not subject to tax.” — Legal Information Institute, Fla.

The IRS explains: “P.L. 119-21, commonly known as the One Big Beautiful Bill Act, reinstated the 100% special depreciation allowance for certain qualified property acquired and placed in service after January 19, 2025 (including long production period property and certain aircraft), and certain specified plants bearing fruits and nuts planted or grafted after January 19, 2025.” — Internal Revenue Service, Publication 946 (2025), How To Depreciate Property, https://www.irs.gov/publications/p946
