Concrete and Masonry Business Entity: LLC or S Corporation for a Crew-Based Contractor With a Winter Shutdown

Concrete and masonry contractors arrive at the entity question with a payroll already running and a season that stops in November — both of which shape the answer. The structures (the LLC cost guide): a single-member LLC on Schedule C — self-employment tax on all net profit, no owner payroll, one return; an LLC electing S status — a reasonable salary through the payroll the crew already uses, remaining profit distributed free of payroll tax, at the cost of Form 1120-S, the incremental payroll cost of adding the owner (small), shareholder-basis tracking, and the state's S corporation layer; a partnership for co-owners; the C corporation, rarely at this scale. The liability layer first: concrete and masonry work generates completed-operations claims (the slab that cracks, the retaining wall that fails, the foundation that settles) and jobsite injury exposure — the LLC (or corporation) is the structure regardless of the tax election, with the insurance (general liability with completed-operations coverage, workers' compensation, commercial auto, umbrella) carrying what the entity doesn't; the tax election sits on top of the liability decision. The reasonable-salary question for a working owner-foreman: the IRS expects the owner to be paid what a comparable employee would earn for the services performed — for a concrete contractor who runs the crew, finishes the pours, estimates, and manages the business, the market comparison is to a working foreman or superintendent in the local construction market, adjusted for the owner's management and sales roles — a figure that for most owner-operators lands in the US$60,000-to-US$95,000 range depending on the market, the crew size, and the specialty (a masonry contractor doing custom stonework commands more); documented with market data and the owner's actual roles, revisited annually, and set honestly because a salary well below a foreman's market wage is the S corporation's audit issue. The saving: payroll tax avoided on the distribution portion (profit above salary) — a contractor netting US$180,000 with a US$80,000 salary saves payroll tax on US$100,000 (about US$14,000 before the election's costs, with the wage base approached); a contractor netting US$110,000 with a US$75,000 salary saves payroll tax on US$35,000 (about US$5,000). The crew-payroll advantage: a concrete contractor with a crew already runs federal and state withholding, unemployment insurance, workers' compensation, quarterly 941s, W-2s, and — on public jobs — certified payroll; adding the owner as an employee costs almost nothing incremental, so the S election's real costs are the 1120-S and the basis tracking, and the profit threshold at which the election pays is lower than for a solo tradesperson creating a payroll for one (the appliance repair and chimney sweep entity guides show the solo case). The winter shutdown: work stops from late November through February or March in northern markets — no pours, no revenue, and the S corporation's owner salary still due on the payroll schedule; the options are a reserve built in the season (the estimated-tax guide's reserve discipline applied to salary), a seasonal salary schedule (higher payroll in season, lower in winter — permissible if the annual total is reasonable and documented, with the crew's own seasonal layoffs as the parallel), or a steady base with a season-end bonus in November (payroll-taxed, timed to the cash); a contractor who already manages crew payroll through the shutdown (unemployment claims, seasonal layoffs, rehires in March) has the cash-planning muscle, and the owner's salary joins that plan. The equipment interaction: concrete contractors buy equipment in lumps — a skid steer year, a truck year — and bonus depreciation on those purchases (the deductions guide) depresses that year's profit; the election's arithmetic runs on normalized profit (a typical year), and the election's effective date can follow a write-off year so the first S corporation year shows the profit the election is meant to shelter. The qualified business income deduction: concrete and masonry is not a specified service trade, so the 20% deduction applies at all income levels subject to the wage-and-property limitation — satisfied easily by a contractor with crew payroll and equipment; the S election's effect is the standard trade (the salary leaves the QBI base, costing 20% of the salary in deduction; the W-2 wages — the crew's and the owner's — support the limitation), outweighed by the payroll-tax saving above the threshold. The profit bands, for a crew-based contractor: net profit under about US$90,000 — Schedule C (the distribution portion above a foreman's salary is small, even with the payroll advantage); US$90,000 to US$140,000 — the worksheet, with the payroll advantage tipping many contractors in this band toward the election; above US$140,000 — the election usually wins, and the analysis is the salary level, the state layer, and the winter salary schedule. The co-owner case: two partners in a concrete business (common — a finisher and a mason, or two brothers) face two salaries against the shared profit, with the partnership's self-employment tax on both shares as the comparison and the S election adding two W-2s to the crew payroll; the partnership's guaranteed payments and the S corporation's salaries are the parallel structures. The public-work wrinkle: prevailing-wage jobs set the crew's wages by the wage determination — and an owner who works on a public job is, as an S corporation employee, subject to the same certified payroll reporting for hours worked on the job, a compliance item the Schedule C owner doesn't have (the owner's own hours on a prevailing-wage job are the owner's, not an employee's, under Schedule C) — a small administrative point that the certified-payroll process absorbs. The annual re-run: profit swings with the construction market and the equipment cycle; the election is revisited each January with the coming season's salary schedule and cash plan.

Key takeaways

• The LLC is the liability decision — completed-operations and jobsite exposure make it non-negotiable; the S election is the tax decision on top of it.
• The crew payroll is the S election's advantage: adding the owner to a running payroll costs almost nothing, so the profit threshold is lower than for a solo tradesperson.
• Reasonable salary for a working owner-foreman is a foreman's or superintendent's market wage adjusted for management — typically US$60,000–95,000 — documented and revisited.
• The winter shutdown needs a salary plan: a season-built reserve, a documented seasonal salary schedule paralleling the crew's layoffs, or a steady base with a November bonus.
• Normalize for equipment years; not a specified service trade — the QBI deduction applies at all levels with the limitation easily met.
• Profit bands: under US$90,000 — Schedule C; US$90,000–140,000 — the worksheet, tipping toward the election; above US$140,000 — usually elect.

Fifteen minutes each January before the season starts.

Worked example

Two concrete contractors in the same northern market. Contractor one: an owner-operator with a two-person crew, netting US$105,000 in a normal year, mostly residential flatwork. Reasonable salary for a working foreman in his market: about US$68,000. Distribution portion: US$37,000; payroll tax saved: about US$5,400. Election costs: the 1120-S plus the small incremental cost of adding himself to the crew's payroll — a few thousand — and the winter plan (a US$4,000 monthly base through the shutdown, funded from a season reserve). Net: modestly positive; he elects, because the payroll already exists and the reserve discipline is one he already runs for the crew's seasonal layoffs. Contractor two: a masonry and concrete firm with a six-person crew, custom stonework, municipal sidewalk contracts, netting US$210,000 in a normal year (this year's skid steer and truck purchases depressed it — the worksheet uses the normalized figure). Reasonable salary for a working superintendent-owner with a stonework specialty: about US$92,000. Distribution portion: US$118,000; payroll tax saved: about US$15,000 (the wage base approached). Election costs: the 1120-S and basis tracking — the payroll runs for six already, with certified payroll on the municipal work absorbing the owner's hours on those jobs. QBI: the salary leaves the base; the crew's W-2 wages satisfy the limitation many times over. Winter plan: a US$5,500 monthly base through the shutdown from a reserve built in the season, and a US$26,000 bonus in November when the last pours are billed. Net saving: low five figures annually. He elects, effective the year after the equipment write-offs, with the salary memo and the seasonal schedule in the file. Both elected — the crew payroll made the election cheap enough at US$105,000 that the solo appliance technician at the same profit would not have reached.

The IRS states that "S corporations are corporations that elect to pass corporate income, losses, deductions, and credits through to their shareholders for federal tax purposes." Shareholder-employees who perform services must be paid reasonable compensation as wages before distributions, and the election is made on Form 2553. — Internal Revenue Service, S corporations, https://www.irs.gov/businesses/small-businesses-self-employed/s-corporations

The IRS states that "the deduction allows eligible taxpayers to deduct up to 20 percent of their QBI, plus 20 percent of qualified real estate investment trust (REIT) dividends and qualified publicly traded partnership (PTP) income," subject to limitations that depend on taxable income and the type of trade or business. — Internal Revenue Service, Qualified business income deduction, https://www.irs.gov/newsroom/qualified-business-income-deduction

Practitioner note

The concrete contractor's S election is cheaper than most trades' because the crew payroll already runs — adding the owner is the 1120-S and a basis schedule — and it needs a winter plan the year-round trades don't, because the salary is due in January when nothing is pouring. Our worksheet normalizes for the skid-steer years, sets the salary from a working foreman's market wage, and writes the winter salary schedule into the same plan the crew's seasonal layoffs already follow; the LLC, meanwhile, is not a tax decision at all in a trade whose slabs can crack.
