Siding installation is a materials-heavy trade with moderate equipment needs. Materials typically run 35-45% of revenue, with the type of siding driving the cost (vinyl is cheapest, fiber cement is mid-range, metal and wood are highest). The defining piece of equipment is the brake machine (metal bender) used to fabricate custom trim, flashing, and metal siding panels on site. Beyond that, the tool requirements are relatively modest: nail guns, scaffolding, cutting tools, and a service vehicle. Siding installation isn’t a specified service trade or business (SSTB) under IRC 199A, so the full QBI deduction applies at all income levels.

How does siding type affect your tax deductions?

Hypothetical example

Round numbers. A siding installer completes 25 jobs per year. Comparison of three specializations:

Vinyl specialist:

Average job: $12,000
Materials: $4,200 (35%)
Labor: $3,600
Overhead allocation: $1,200
Net profit per job: $3,000 (25%)
Annual revenue: $300,000
Annual net profit: $75,000
Tax (sole proprietor): approximately $17,700
Effective rate: 23.6%

Fiber cement specialist:

Average job: $20,000
Materials: $8,000 (40%)
Labor: $5,000
Overhead allocation: $2,000
Net profit per job: $5,000 (25%)
Annual revenue: $500,000
Annual net profit: $125,000
Tax (sole proprietor): approximately $35,700
S-Corp tax (salary $65,000): approximately $27,200
S-Corp savings: $8,500/year

Cedar/premium specialist:

Average job: $30,000
Materials: $13,500 (45%)
Labor: $7,500
Overhead allocation: $3,000
Net profit per job: $6,000 (20%)
Annual revenue: $750,000 (may need 3-4 crew members)
Annual net profit: $150,000
Tax (sole proprietor): approximately $44,700
S-Corp tax (salary $70,000): approximately $33,500
S-Corp savings: $11,200/year

The deduction pattern: Higher-end siding (cedar, metal) has higher materials cost per job but also higher total revenue and profit. The S-Corp break-even ($70,000-$85,000 net profit) is reached sooner with premium materials because per-job profit is higher.

Equipment depreciation impact (Year 1): A siding installer who buys a truck ($45,000), brake machine ($8,000), scaffolding ($5,000), trailer ($8,000), and tools ($4,000) = $70,000 total. At 100% bonus depreciation, the $70,000 deduction saves $27,510 at the 39.3% combined rate.
