Pool service is a route-based business where the two dominant expense categories are chemicals (15-25% of revenue) and vehicle costs (10-15% of revenue). Unlike most trade businesses where labor is the overwhelming input, pool service has a meaningful materials component because every visit consumes chlorine, acid, algaecide, or other treatment products. This makes accurate chemical tracking important for both tax deductions and job costing. The vehicle is the second-largest deduction, as pool technicians drive between accounts all day. A solo operator servicing 50-70 pools typically drives 15,000-25,000 business miles per year, worth $10,500-$17,500 at the 70 cent standard mileage rate (2025).

✓Key takeaway

Pool service deductions:

Chemicals and supplies (COGS, 15-25% of revenue):

Salt (for salt chlorine generators): $200-$500/year
Specialty chemicals (stain removal, metal sequestrant, phosphate remover): $300-$1,000/year
Test reagents and strips: $200-$500/year
Total chemicals: $4,000-$12,000/year depending on pool count and pool types

Service vehicle (van or truck): $20,000-$45,000
Chemical storage tank/rack system: $500-$2,000
Pool vacuum (portable): $200-$600

Vehicle and route expenses:

Standard mileage: 70 cents per mile (2025)
50 pools, average 5 miles between stops = 250 miles/week x 50 weeks = 12,500 miles (route only)
Add driving to first/last pool from home office: 3,000-5,000 miles/year
Total: 15,000-20,000 business miles = $10,500-$14,000 deduction
If using actual expenses: fuel + maintenance + insurance + depreciation, prorated by business use percentage

Converts the first drive of the day from commuting (not deductible) to business mileage (deductible)
Simplified method: $5/sqft, max $1,500

What does a pool service owner’s tax picture look like?

Hypothetical example

Round numbers. A solo pool technician servicing 55 residential pools. Weekly maintenance at $175/month average. Single filer.

Revenue:

Source	Amount
Weekly maintenance (55 x $175 x 12)	$115,500
Pool openings (45 pools x $300)	$13,500
Pool closings (45 pools x $300)	$13,500
Repairs (filters, pumps, heaters)	$15,000
Chemical delivery (add-on)	$3,500
Total revenue	$161,000

Deductions:

Category	Amount
Chemicals and supplies	$24,000
Parts for repairs (customer cost, marked up)	$8,000
Vehicle mileage (18,000 miles x $0.70)	$12,600
Insurance (GL + vehicle + equipment)	$3,500
Marketing (Google Ads + website)	$5,000
Phone (80% business)	$960
Software (scheduling, invoicing)	$600
CPO renewal (prorated)	$100
Home office (simplified, 200 sqft)	$1,000
Uniforms, safety equipment	$400
Total deductions	$56,160

Tax calculation (sole proprietor):

Net profit: $161,000 - $56,160 = $104,840
SE tax: $104,840 x 92.35% x 15.3% = $14,812
SE deduction: ($7,406)
QBI deduction: $104,840 x 20% = ($20,968)
Taxable: $104,840 - $7,406 - $20,968 - $15,000 = $61,466
Income tax: approximately $8,600
Total tax: $23,412
Effective rate: 14.5% of revenue

If the tech buys a new service van (over 6,000 lbs, $35,000):

Bonus depreciation: $35,000 (but can’t use standard mileage in the same year for this vehicle)
Switch to actual expenses for this vehicle: fuel ($4,500) + maintenance ($1,200) + insurance ($2,000) + depreciation ($35,000) = $42,700
Replaces the $12,600 mileage deduction with $42,700 actual expenses
Net additional deduction: $30,100
Tax savings: $30,100 x 33% = approximately $9,933 in Year 1
Year 2 (no depreciation remaining): actual expenses drop to approximately $7,700, LESS than standard mileage would have been
Decision: standard mileage is often better for pool service long-term because routes generate high mileage, and the 70 cent rate includes depreciation. The actual method wins in Year 1 only if buying a heavy vehicle.

Route acquisition: If the tech buys a 20-pool route for $42,000 (12x monthly of $3,500):

Amortized over 15 years: $42,000 / 15 = $2,800/year
Tax savings: $2,800 x 33% = $924/year for 15 years
The route adds $42,000/year in recurring revenue
Payback period: approximately 12 months (before tax savings)
