Chimney sweeping is one of the highest-margin trades in the home services industry. Materials cost is only 5-15% of revenue (brushes, rods, and drop cloths are reusable; chimney caps and liners are marked up when sold to customers). Labor is the primary cost, and for a solo operator, that labor is the owner’s time. The deduction profile is dominated by vehicle costs, inspection equipment, and marketing. From a tax standpoint, chimney sweeping isn’t a specified service trade or business (SSTB), so the full QBI deduction under IRC 199A is available regardless of income level.

What deductions can a solo chimney sweep claim?

Hypothetical example

Round numbers. A solo chimney sweep, Year 1 of operations. Performs 400 cleanings/inspections per year at $200 average, plus 50 cap installations at $400 average.

Revenue:

Cleaning/inspection: 400 x $200 = $80,000
Cap installations: 50 x $400 = $20,000
Liner installations: 10 x $3,500 = $35,000
Repairs: 30 x $500 = $15,000
Total revenue: $150,000

Year 1 equipment purchases:

HEPA vacuum	$1,500	Bonus depreciation
Thermal camera	$2,000	Bonus depreciation

Year 1 tax calculation:

Gross profit: $136,500
Operating expenses: $18,200
Equipment depreciation (bonus): $58,500
Net profit: $59,800

Tax (single filer, sole proprietor):

SE tax: $59,800 x 92.35% x 15.3% = $8,449
Income tax (after deductions): approximately $4,800
QBI savings: approximately $2,600
Total tax: approximately $10,649
Effective rate: 17.8%

Year 2 (no major equipment purchases):

Revenue: $150,000
COGS: $13,500
Operating expenses: $18,200
Depreciation: $1,000 (small tools only)
Net profit: $117,300
Total tax: approximately $28,500
Jump from Year 1: $10,649 to $28,500

The high margin (78% gross margin on cleaning) means that once equipment is depreciated, a large portion of revenue flows directly to taxable profit.
