Garage door repair and installation is a trades business with a clear service model: emergency spring replacements, opener installations, panel replacements, and new full-door installations. Revenue per call is high ($200-$800 for repairs, $800-$2,500+ for new installations), and the business scales with technician count and marketing spend. For tax purposes, garage door repair isn’t a specified service trade or business (SSTB) under IRC 199A, which means the qualified business income (QBI) deduction has no income-based phase-out.

✓Key takeaway

Garage door repair tax structure:

SSTB status: NOT an SSTB. Garage door repair and installation is a skilled trade. The QBI deduction (up to 20% of qualified business income) applies at all income levels, with no phase-out based on taxable income.

Sole proprietorship / single-member LLC (default):

Net profit reported on Schedule C
Self-employment tax: 15.3% on net income (12.4% Social Security up to $176,100 in 2025, 2.9% Medicare on all income)
QBI deduction: up to 20% of net income
Simple, low-cost, no payroll required

S-Corp (LLC with S election):

Owner pays themselves a reasonable W-2 salary
Reasonable salary for a garage door technician-owner: $45,000-$65,000 depending on market, volume, and whether the owner still does installations
Profit above salary is distributed as S-Corp distributions (no FICA)
FICA savings on the distribution amount

S-Corp break-even for garage door repair:

Workers’ comp: 5-10% of payroll (moderate risk, working at heights, heavy doors)
S-Corp admin costs: $1,000-$2,000/year (payroll service, additional tax return)
Break-even: approximately $70,000-$80,000 net income
Below $70,000: the FICA savings do not cover the additional costs
At $100,000 net: approximately $3,000-$4,000/year in net savings
At $150,000 net: approximately $7,000-$9,000/year in net savings

What does the S-Corp save for a garage door repair business?

Hypothetical example

Round numbers. A sole proprietor garage door repair business. Net profit: $120,000. Single filer.

As sole proprietorship:

SE tax: $120,000 x 92.35% x 15.3% = $16,942
QBI deduction: $120,000 x 20% = $24,000
Taxable income: $120,000 - $6,471 (half SE) - $15,000 (standard deduction) - $24,000 (QBI) = $74,529
Income tax: approximately $11,500
Total tax: $28,442

As S-Corp (reasonable salary: $55,000):

FICA on salary: $8,415 (employee + employer)
Workers’ comp on salary: $4,400 (8% estimate)
Distribution: $120,000 - $55,000 - $4,400 = $60,600
FICA on distribution: $0
QBI (distribution only for S-Corp): $60,600 x 20% = $12,120
Taxable income: $55,000 + $60,600 - $15,000 - $12,120 = $88,480
Income tax: approximately $14,000
S-Corp admin costs: $1,500
Total tax + costs: $28,315

Net S-Corp savings: approximately $127/year

At 8% workers’ comp, the S-Corp barely breaks even at $120,000 net profit because the insurance cost eats most of the FICA savings. The rate varies by state and claims history:

Revised (workers’ comp at 5%):

Workers’ comp: $55,000 x 5% = $2,750
Distribution: $120,000 - $55,000 - $2,750 = $62,250
FICA savings: $16,942 - $8,415 = $8,527
Less workers’ comp: ($2,750)
Less admin: ($1,500)
Net savings: $4,277/year

The workers’ comp rate is the deciding factor. At 5%, the S-Corp saves $4,277. At 8%, it barely breaks even. Garage door repair owners should get their actual workers’ comp rate before making the S-Corp election.

Key revenue drivers affecting the tax picture:

Spring replacement: $200-$400 (high margin, 30-minute job)
Opener installation: $300-$600 (moderate margin, 1-2 hour job)
Full door replacement: $800-$2,500 (includes materials, lower margin percentage but higher dollar profit)
A busy owner-operator doing 6-8 calls/day at an average of $350/call generates $500,000+ annual revenue
With 1-2 employees: net profit to the owner can exceed $150,000

At $150,000+ net profit, the S-Corp clearly saves money even with higher workers’ comp rates.
