Pool service businesses have a cost structure dominated by vehicle expenses and chemicals. A pool tech visits 8-15 pools per day, driving between accounts in a route pattern, making the vehicle the most-used business asset. Chemicals (chlorine, muriatic acid, calcium hypochlorite, salt, stabilizer) are consumed at every stop and represent 10-15% of revenue. Equipment costs are moderate (a pool pole, vacuum, test kit, and basic tools cost $2,000-$5,000 to start), with specialty items like variable-speed pumps, salt chlorine generators, and automated chemical feeders available as upsell opportunities. The combination of high mileage, regular chemical purchases, and a dedicated service vehicle makes the pool service business’s deduction profile straightforward but substantial.

✓Key takeaway

Pool service deduction categories:

Vehicle expenses (the largest deduction): Pool techs drive more per customer than almost any service trade (short hops between pools all day, every day).

Metric	Amount
Pools serviced per day	10-15
Miles between pools (avg)	3-5
Daily miles	30-75
Working days per year	250
Annual business miles	7,500-18,750
Standard mileage deduction (70 cents)	$5,250-$13,125

Most pool service trucks/vans are over 6,000 lbs GVWR (loaded with chemicals, equipment, and tools):

Ford E-250/E-350 van: over 6,000 lbs = full Section 179
Chevy Express: over 6,000 lbs = full Section 179
Toyota Tacoma/smaller trucks: CHECK GVWR (may be under 6,000 lbs)

Chemicals (10-15% of revenue):

Chemical	Monthly Cost (80 pools)	Annual
Liquid chlorine (sodium hypochlorite)	$300-$600	$3,600-$7,200
Muriatic acid	$100-$200	$1,200-$2,400
Calcium hypochlorite (granular)	$50-$150	$600-$1,800
Stabilizer (cyanuric acid)	$50-$100	$600-$1,200
Salt (for salt pools)	$50-$100	$600-$1,200
Algaecide, clarifier, specialty	$50-$100	$600-$1,200
Total chemicals	$600-$1,250/month	$7,200-$15,000

All chemicals consumed on customer pools are deductible as supplies in the year purchased. Bulk purchases of chlorine stored in the truck are deductible when purchased (not when used) for cash-basis small businesses under the de minimis safe harbor.

Equipment:

Equipment	Cost	Life/Depreciation
Pool poles (telescoping, multiple)	$100-$300	Replace annually (deduct as supplies)
Vacuum head and hose	$100-$300	Replace 1-2x per year
Test kit (Taylor K-2006 or digital)	$50-$200	Replace annually
Leaf rake, wall brush, tile brush	$50-$150	Replace as needed
Backwash hose, garden hose	$50-$100	Replace as needed
Chemical storage containers	$100-$300	Last 3-5 years
Pool pump (for repairs/replacement sales)	$500-$2,000	Section 179 if sold separately
Chemical feeder/automation controller	$500-$2,000	Section 179
Pressure washer (deck cleaning add-on)	$300-$800	Section 179
Total equipment startup	$1,850-$6,150

Other deductions:

Category	Annual Amount
Insurance (GL + commercial auto)	$2,000-$4,500
Phone/internet (business %)	$600-$1,200
Pool service software (PoolBrain, Skimmer, Service Autopilot)	$300-$1,200
Marketing (door hangers, yard signs, Google Local)	$1,000-$3,000
Uniforms (company shirts, hats)	$200-$500
CPO certification (Certified Pool Operator)	$300-$400 (every 5 years)
Licensing (state/county pool contractor)	$100-$500
Subcontractor payments (vacation coverage)	Varies

What does the full deduction picture look like?

Hypothetical example

Round numbers. A pool service sole proprietor. Year 2. 80 weekly accounts at $150/month average. Single filer.

Revenue: 80 pools x $150/month x 12 months = $144,000 Plus repair/equipment sales: $16,000 Total revenue: $160,000

Expenses:

Category	Amount
Chemicals	$12,000
Vehicle (standard mileage, 15,000 mi x $0.70)	$10,500
Insurance (GL + auto)	$3,500
Equipment replacement/repair parts	$3,000
Subcontractor (vacation weeks)	$2,400
Software (Skimmer + QuickBooks)	$900
Marketing	$1,800
Phone/internet	$1,000
Uniforms	$400
CPO certification (amortized)	$80
Accounting/bookkeeping	$1,200
Total expenses	$36,780

Net profit: $123,220

Tax (sole proprietor):

SE tax: $123,220 x 92.35% x 15.3% = $17,404
Income tax: approximately $14,500
QBI deduction: $123,220 x 20% = $24,644 (saves $5,422)
Total tax: $26,482

With S-Corp ($55,000 salary):

FICA: $55,000 x 15.3% = $8,415
Income tax: approximately $14,500
QBI deduction: same $24,644 (below threshold, no W-2 wage limit)
S-Corp admin: $2,500
Total: $19,993

S-Corp savings: $6,489/year

Actual expense method vs. standard mileage: Pool service vehicles are heavily used (daily routes, chemical loading, wear). Actual expenses may be higher:

Actual Expense	Annual Cost
Gas ($4.00/gal, 12 mpg, 15,000 mi)	$5,000
Insurance (commercial auto)	$2,500
Repairs/maintenance	$3,000
Depreciation (Section 179 in Year 1, MACRS after)	$5,000-$7,000
Tires (replace every 18 months in pool service)	$800
Registration/fees	$300
Total actual expenses	$16,600-$18,600

Actual expenses ($16,600-$18,600) vs. standard mileage ($10,500): actual expenses are $6,100-$8,100 higher. For a dedicated pool service vehicle (100% business use), the actual expense method almost always produces a larger deduction because of the high maintenance/repair costs and fuel consumption of driving stop-and-go routes all day.

Important: if the vehicle was first used for the standard mileage method, the owner can switch to actual expenses in a later year. But if actual expenses (with MACRS depreciation) were used first, the owner Can’t switch to standard mileage for that vehicle.

Route density as a tax factor: A tight route (3 miles between pools): 30 miles/day, $5,250/year mileage deduction A spread-out route (7 miles between pools): 70 miles/day, $12,250/year mileage deduction

The spread-out route generates $7,000 more in deductions but also costs $3,500 more in fuel. Net tax benefit of the longer route: $7,000 x 25% tax savings = $1,750, minus $3,500 fuel = negative $1,750.

Conclusion: route density saves money (lower fuel, faster service, more pools per day). The higher mileage deduction on spread routes doesn’t compensate for the actual cost of driving more. Optimize routes for density, not deductions.
