Electrical contracting is a high-demand, license-required trade with strong growth drivers from EV charger installations, solar panel work, home automation, and the broader electrification trend. The business is NOT a Specified Service Trade or Business (SSTB) under IRC 199A, meaning the full 20% QBI deduction applies at all income levels. Material costs are moderate (15-25% of revenue for service work, 25-40% for new construction), placing electrical work between service-heavy trades (plumbing repair, HVAC service) and material-heavy trades (roofing). Licensing requirements (journeyman or master electrician license) create a barrier to entry that supports higher hourly rates and limits competition. A licensed electrician’s billable rate ($75-$150/hour) is among the highest in the residential trades.

✓Key takeaway

Electrical contractor tax profile:

SSTB classification: NOT an SSTB

Electrical installation, repair, and service is a trade service
Full QBI deduction at all income levels
No phase-out above $266,950 (single) / $533,900 (MFJ)

Revenue model:

Service/repair call: $150-$500
Panel upgrade (100 to 200 amp): $2,000-$4,000

Generator installation: $5,000-$15,000
New construction (per house): $5,000-$15,000
Commercial electrical: $10,000-$100,000+ per project
Smart home/automation: $2,000-$10,000
Average solo electrician: $100,000-$250,000/year
Small company (2-3 employees): $300,000-$800,000/year

Revenue mix (residential service focus):

Revenue Stream	% of Total	Margin
Service/repair calls	30-40%	55-70%
Panel upgrades	15-20%	40-55%
EV charger installs	10-15%	45-60%
Generator installs	10-15%	35-45%
New construction	10-20%	25-35%
Lighting/ceiling fans	5-10%	50-65%

Cost structure (solo electrician):

Materials: 15-25% of revenue
Van/vehicle operating: 5-8%
Insurance: 3-5%
Tools: 1-2%
Licensing/continuing education: 1%
Net margin: 55-70%

Major investments:

Equipment	Cost	Section 179
Service van (cargo)	$30,000-$50,000	Yes (over 6,000 lbs)
Van shelving/organization	$2,000-$4,000	Yes
Power tools (drill, saw, etc.)	$1,000-$3,000	Yes
Test equipment (multimeter, circuit tracer, etc.)	$500-$2,000	Yes
Wire pulling equipment	$500-$1,500	Yes
Conduit bender set	$300-$800	Yes
Generator (for job sites)	$500-$2,000	Yes
Total solo	$35,000-$63,000

S-Corp analysis:

Licensed electricians command high wages as employees ($50,000-$75,000)
This higher salary benchmark reduces the S-Corp distribution (and savings)
S-Corp break-even: approximately $65,000-$75,000 net profit
At $130,000 net: S-Corp saves approximately $4,500-$5,500/year
Reasonable salary: $50,000-$65,000 (master electrician running own business)

How should an electrical business be structured for taxes?

Hypothetical example

Round numbers. A solo master electrician. Year 2. Single filer. Residential service and installations.

Revenue: $200,000

Service calls (300 at $300 avg): $90,000
Panel upgrades (15 at $3,000): $45,000
EV charger installs (20 at $2,000): $40,000
Generator installs (3 at $8,000): $24,000
Miscellaneous: $1,000

Expenses: $50,000

Materials: $30,000
Van operating: $8,000
Insurance: $4,000
Tools/equipment: $2,000
License/CE: $500
Marketing: $3,000
Phone/software: $1,500
Home office: $1,000

Net profit: $150,000

Sole proprietorship:

SE tax: $150,000 x 92.35% x 15.3% = $21,186
QBI: $150,000 x 20% = $30,000
Taxable: $150,000 - $10,593 - $15,000 - $30,000 = $94,407
Income tax: $15,635
Total: $36,821
Effective rate: 24.5%

S-Corp ($60,000 salary):

FICA: $60,000 x 15.3% = $9,180
Distribution: $150,000 - $60,000 - $4,590 = $85,410
QBI: $85,410 x 20% = $17,082
Taxable: $145,410 - $15,000 - $17,082 = $113,328
Income tax: $18,786
S-Corp costs: $2,500
Total: $30,466
Effective rate: 20.3%

S-Corp saves: $6,355/year

Reasonable salary justification for electricians:

Master electricians earn $55,000-$80,000 as employees (BLS)
Journeyman electricians earn $40,000-$60,000
$60,000 for a master electrician running a service business is defensible
The remaining $85,410 reflects business reputation, customer relationships, licensing value, and equipment investment

EV charger installation as a growth driver: EV charger installations are one of the fastest-growing revenue streams for residential electricians:

Average installation: $1,500-$3,000 (Level 2, NEMA 14-50 or hardwired)
Material cost: $300-$800 (charger, wire, breaker)
Labor: 3-6 hours
Margin: 45-60%
Federal tax credit for the customer: 30% of cost (up to $1,000) under IRC 30C
The customer’s tax credit doesn’t affect your revenue but creates demand

Growth rate: EV charger installs grew 40-60% year-over-year in 2023-2025. A solo electrician doing 20 EV installs/year at $2,000 each = $40,000 in additional revenue. At 55% margin = $22,000 net profit.

Licensing as an economic moat: The master electrician license is one of the strongest competitive advantages in the trades:

Takes 4-8 years of apprenticeship + journeyman experience
Exam pass rates: 50-70% (difficult)
Limits competition (you can’t just “start an electrical business” without the license)
Supports higher hourly rates ($75-$150/hr vs. $40-$75 for unlicensed trades)
The licensing cost and continuing education are deductible

For tax purposes, if you sell the business, the license doesn’t transfer. But the customer list, reputation, phone number, and trained employees DO transfer, and those intangible assets are valued (and amortized by the buyer under IRC 197).
