Window cleaning is a high-margin, low-capital business where the vehicle is almost always the largest deductible expense. Equipment costs are modest compared to other trades (a full setup runs $3,000-$8,000 vs. $50,000+ for an HVAC installer or plumber). That means tax planning for window cleaners centers on the vehicle deduction, the right entity structure, and making sure every supply and operating expense gets captured.

✓Key takeaway

Major deductions for window cleaning businesses:

Equipment (Section 179 or de minimis safe harbor):

Water-fed pole systems: $1,500-$5,000 (deduct in full under de minimis safe harbor if under $2,500, or Section 179 if higher)
Squeegees, scrapers, extension poles: $200-$500 each
Pressure washer (for exterior/commercial): $500-$3,000
Ladders (extension and step): $300-$1,500
Safety harnesses and anchor systems (high-rise): $500-$2,000
Bucket, holster, and belt systems: $100-$300

Supplies (ordinary and necessary, deduct as incurred):

Cleaning solutions and detergents: $500-$2,000/year
Towels, rags, microfiber cloths: $200-$500/year
Replacement rubber, blades, and tips: $300-$800/year
Gloves, shoe covers, drop cloths: $200-$400/year

Vehicle (usually the largest single deduction):

Standard mileage rate (2025): 70 cents per mile
At 15,000-20,000 business miles/year: $10,500-$14,000 deduction
OR actual expenses: fuel, insurance, maintenance, depreciation (pro-rated for business use percentage)
Van or SUV over 6,000 lbs GVWR qualifies for Section 179 (up to $31,300 for SUVs, unlimited for vans and trucks)
A cargo van ($30,000-$45,000) is the typical window cleaning vehicle and qualifies for full Section 179

Insurance:

General liability: $500-$1,500/year
Commercial auto: $1,200-$3,000/year
Workers’ comp (if employees): 5-8% of payroll (low-risk classification)

Invoicing/payment processing: 2.5-3.5% per transaction
Route optimization software: $20-$50/month

What does a window cleaning owner’s Year 1 tax look like?

Hypothetical example

Round numbers. A sole proprietor starts a window cleaning business. Revenue: $120,000 (first full year). Files as single.

Revenue: $120,000

Deductions:

Vehicle (18,000 miles x $0.70): $12,600
Equipment purchased (water-fed pole, squeegees, pressure washer, ladders): $6,000
Cleaning supplies: $1,500
General liability insurance: $1,000
Commercial auto insurance: $2,000
Marketing (Google Ads, vehicle wrap, website): $8,000
Software (CRM, invoicing): $1,800
Phone (business portion): $600
Uniforms and protective gear: $500
Total deductions: $34,000

Net profit: $86,000

Self-employment tax: $86,000 x 92.35% x 15.3% = $12,141 Income tax (single, standard deduction $15,750, QBI deduction ~$17,200):

Taxable income: $86,000 - $6,071 (half SE tax) - $15,000 - $17,200 = $47,729
Federal income tax: approximately $5,600
Total federal tax: $17,741 (effective rate: 20.6%)

S-Corp analysis at $86,000 net: Window cleaning has low workers’ comp rates (5-8% of payroll), so the S-Corp break-even is around $70,000 net income.

Reasonable salary: $45,000
FICA on salary: $6,885 (employee + employer)
Workers’ comp on salary: $2,700 (6% estimate)
Distribution: $86,000 - $45,000 - $2,700 = $38,300 (no FICA)
FICA savings: $12,141 - $6,885 = $5,256
Less workers’ comp cost: ($2,700)
Less S-Corp admin costs: ($1,500)
Net annual savings from S-Corp: approximately $1,056

At $86,000 net, the S-Corp saves about $1,000/year after accounting for workers’ comp and admin costs. The savings grow significantly at $100,000+ net income. Below $70,000 net, the S-Corp is not worth the complexity for window cleaning businesses.
