Fence installation is a construction trade with a materials-heavy revenue model. A typical residential fence job runs $3,000-$8,000, with materials (wood, vinyl, aluminum, chain link, posts, concrete) representing 40-50% of the invoice. The remaining 50-60% covers labor, equipment, and profit. For tax purposes, fence installation isn’t a specified service trade or business (SSTB) under IRC 199A, so the QBI deduction applies at all income levels.

✓Key takeaway

Fence installation tax structure:

SSTB status: NOT an SSTB. Full QBI deduction available regardless of income.

Revenue model affects tax planning:

Materials: 40-50% of revenue (deducted as COGS or supplies)
Labor (if employees): 15-25% of revenue
Equipment and vehicle: 5-10% of revenue
Net profit to owner: 15-30% of revenue
A $500,000 revenue fence company may net $75,000-$150,000 to the owner

Workers’ compensation:

Fence installation (NCCI code 6400 or similar): 8-15% of payroll depending on state
Lower than concrete/roofing but higher than many service businesses
The rate applies to the owner’s salary in an S-Corp

S-Corp break-even: approximately $80,000-$100,000 net income (varies by workers’ comp rate)

Equipment (mostly modest):

Post hole digger/auger: $500-$3,000
Concrete mixer (portable): $300-$1,000
Compactor: $500-$2,000
Truck and trailer: $30,000-$60,000 (Section 179 if truck over 6,000 lbs GVWR)
Saws (miter, circular, reciprocating): $200-$500 each
Hand tools: $500-$2,000 total

What does the S-Corp save for a fence installation business?

Hypothetical example

Round numbers. A sole proprietor fence installer. Revenue: $400,000. Materials: $180,000 (45%). Labor (2 employees): $80,000. Other expenses (vehicle, insurance, marketing, tools): $40,000. Net profit: $100,000. Single filer.

As sole proprietorship:

SE tax: $100,000 x 92.35% x 15.3% = $14,130
QBI deduction: $100,000 x 20% = $20,000
Taxable income: $100,000 - $7,065 - $15,000 - $20,000 = $57,935
Income tax: approximately $7,700
Total tax: $21,830

As S-Corp (reasonable salary: $50,000):

FICA on salary: $7,650
Workers’ comp on owner salary: $50,000 x 10% = $5,000
Distribution: $100,000 - $50,000 - $5,000 = $45,000
QBI: $45,000 x 20% = $9,000
Taxable income: $50,000 + $45,000 - $15,000 - $9,000 = $71,000
Income tax: approximately $9,800
S-Corp admin: $1,500
Total tax + costs: $23,950

S-Corp is MORE EXPENSIVE by $2,120/year at $100,000 net with 10% workers’ comp.

At $130,000 net:

Sole prop SE tax: $18,355
S-Corp FICA: $7,650
Workers’ comp: $5,000
FICA savings: $10,705
Less workers’ comp + admin: ($6,500)
Net savings: $4,205/year

At $80,000 net:

FICA savings: $4,290
Workers’ comp + admin: $6,500
Net cost: ($2,210)

The S-Corp break-even for fence installation is around $110,000-$120,000 net income with 10% workers’ comp. This is higher than many business owners expect. The materials-heavy model means revenue must be much higher than the net profit suggests, and the workers’ comp cost on the owner’s salary offsets a significant portion of the FICA savings.

Seasonality matters: Fence installation is seasonal in northern climates (March-November). Revenue peaks in May-August (homeowners want fences for summer). Q1 and Q4 are slow. Use the annualized income method or S-Corp payroll withholding to match tax payments to revenue timing.

What tax deductions are specific to construction businesses?

Construction businesses can deduct job-site costs including materials, subcontractor payments, equipment rental, permits, and bonding fees as cost of goods sold or direct expenses. Tools and small equipment under $2,500 per item can be expensed immediately under the de minimis safe harbor election (Treas. Reg. 1.263(a)-1(f)). Larger equipment qualifies for Section 179 or bonus depreciation. Construction vehicles (dump trucks, excavators, concrete mixers) fall into the 5-year MACRS class. Employee-related costs unique to construction include safety training, PPE, union dues paid on behalf of workers, and travel to remote job sites when the site is temporary (expected to last less than one year under IRC 162(a)). Warranty reserves for callback work can be deducted when the work is performed, not when the reserve is established, unless you elect the recurring-item exception under IRC 461(h)(3).
