Flooring installation is a construction trade that isn’t a Specified Service Trade or Business (SSTB) under IRC 199A. Whether the business installs hardwood, LVP, tile, carpet, or epoxy, the full 20% QBI deduction is available at any income level. The business model involves significant material costs (often 40-50% of the job price), specialized tools, and a work vehicle, all of which create substantial deduction opportunities.

✓Key takeaway

Flooring installer tax structure:

SSTB status: NOT an SSTB. Flooring installation is physical construction/trade work. Full QBI deduction available at any income level.
Material costs. Flooring materials (hardwood, tile, LVP, carpet, adhesives, underlayment, transitions, trim) are a major expense. For a $5,000 flooring job, materials might be $2,000-$2,500. This is cost of goods sold (or materials and supplies for businesses under $30M using the simplified method).
S-Corp threshold. For solo flooring installers, the break-even is approximately $70,000-$90,000 in net profit (after materials). Material costs reduce net profit significantly, so the S-Corp threshold occurs at higher revenue levels than service-only businesses.
Reasonable salary:
- Solo flooring installer: $40,000-$55,000
- Installer with 1-2 helpers: $50,000-$65,000
- Flooring company owner (multiple crews): $65,000-$90,000
Equipment deductions:
- Tile saws ($500-$3,000), miter saws, table saws, nailers, knee kickers, power stretchers
- Floor scrapers, moisture meters, leveling tools
- Work van or truck (Section 179 if GVWR > 6,000 lbs)
- Knee pads, safety equipment, work clothing with company branding
Insurance. General liability (covers damage to the client’s property during installation), commercial auto, workers’ comp (if employees). Flooring installers have moderate workers’ comp rates compared to roofing or electrical.

What does a flooring installer’s tax picture look like?

Hypothetical example

Round numbers. A solo flooring installer (S-Corp) specializing in hardwood and LVP installation. Revenue: $160,000.

Revenue: $160,000

Expenses:

Materials (supplied by installer, 45% of revenue): $72,000
Work van (fuel, insurance, maintenance): $7,000
Tools and equipment: $3,000
Insurance (GL + commercial auto): $3,500
Marketing (Google, Angi, referral fees): $4,000
Phone and software: $1,200
Licensing and CE: $300
Owner salary: $50,000
Employer FICA: $3,825

Total expenses: $144,825 K-1 income: $15,175

This is a low K-1. The material costs consumed 45% of revenue, and the owner salary took another 31%. The S-Corp benefit here is minimal because K-1 income is only $15,175.

Alternative: higher-margin installer (labor-only, customer supplies materials):

Revenue: $120,000 (labor only, lower total revenue)
No material costs (customer buys flooring directly)
Expenses (van, tools, insurance, marketing, phone): $18,700
Owner salary: $50,000
K-1 income: $51,300
QBI deduction: $51,300 x 20% = $10,260
S-Corp FICA savings: approximately $4,500

Key insight: the business model (materials included vs. labor-only) dramatically affects the tax picture. A labor-only flooring installer with $120,000 in revenue has a higher K-1 income ($51,300) than a materials-included installer with $160,000 in revenue ($15,175). The S-Corp is more beneficial for the labor-only model because a larger portion of income flows to K-1 (avoiding FICA).

Recommendation: for flooring installers who supply materials, the S-Corp may not be worth the compliance cost unless revenue exceeds $200,000 (where net profit after materials would be high enough to benefit). For labor-only installers, the S-Corp becomes beneficial at lower revenue levels ($100,000+).

Illustrative numbers only, not a real client and not advice for your facts.

When does it make sense to elect S-Corp taxation for my LLC?

The general rule of thumb is when your net self-employment income consistently exceeds $40,000-50,000 annually. Below that, the S-Corp’s added compliance costs (payroll processing, quarterly payroll tax filings, a separate corporate return) often exceed the FICA savings. The calculation is straightforward: an S-Corp pays FICA only on the owner’s reasonable salary, not on distributions above that salary. If your LLC earns $100,000 and a reasonable salary is $60,000, you save roughly $6,120 in self-employment tax on the $40,000 distributed as profit (15.3% x $40,000). Subtract $2,000-3,000 in added compliance costs for payroll and the separate S-Corp return, and you net $3,000-4,000 in annual savings. File Form 2553 by March 15 for a calendar-year election, or within 75 days of forming the LLC for a mid-year start.
