Most general contractors and trades businesses at $300K–$800K revenue overpay by $15,000 to $40,000 a year. Not because they're cheating themselves — because nobody walked them through the five moves that actually fit a contractor's life. Here they are.
Based on real PilePilot scans for trades clients. Your mileage will vary based on entity, truck purchases, and whether your work involves custom design.
These are the strategies that actually move money — not the "did you remember mileage?" stuff every tax prep service mentions and stops there.
Buy a new F-250, Transit, or Sprinter for the business and write the whole thing off in year one. Heavy trucks >6,000 lbs GVWR get the biggest break. Tools, ladders, compressors, scaffolding, lifts all qualify too. This alone often justifies the equipment purchase.
Read the full breakdown → §1361At $180K of profit, a contractor's SE-tax bill is ~$24K. S-corp election with a reasonable W-2 of $90K–$100K cuts that nearly in half. Set up payroll once, save every year after. The single biggest move for an established trades business.
Read the full breakdown → §3121(b)(3)(A)Teen running materials, cleaning job sites, doing data entry for invoices? They're employees. Pay them up to the standard deduction tax-free, shift income from your bracket to theirs. Document the work. Real wages for real work — a clean strategy.

Read the full breakdown → §41If you're doing custom design-builds, developing new fabrication techniques, prototyping a unique waterproofing method, or running CAD-driven cabinet shops — portions of your labor cost qualify for the federal R&D credit. Most contractors don't realize this applies to them.

James had been running his GC business as a single-member LLC for nine years. Revenue had grown steadily, but he was writing checks to the IRS that hurt and he couldn't tell why. His tax preparer ran TurboTax Self-Employed and called it done. PilePilot's strategy scan pulled four big moves in the first pass plus one nobody had ever mentioned.
Move 1: The truck. James bought a 2025 F-250 in March for $72,800 to replace his 2018 work truck. His prior preparer was going to depreciate it over 5 years. PilePilot flagged it for §179 ($30,500 cap on heavy SUVs/trucks) plus 60% bonus depreciation on the remaining basis. $56,180 deducted in year one instead of $14,560. That's a $13,000+ tax shift right there.
Move 2: S-Corp election. At $184K of profit, the SE-tax savings were obvious. PilePilot generated the late S-Corp election under Rev. Proc. 2013-30, set reasonable wages at $98,000 (defensible for a Philly GC running a small crew), and pulled the remaining profit as a distribution. $14,600 in SE-tax savings, year one alone.
Move 3: His son Marcus on payroll. Marcus (16) had been riding along on Saturdays, hauling materials, running the supply truck. Now he's a part-time W-2 employee at $11,400/yr — under the standard deduction, tax-free to him, deductible to the S-corp. Plus he started a Roth IRA out of his wages.
Moves 4 + 5: Augusta + R&D. James hosts his three-person crew at his house for quarterly planning meetings — fair market rental rate $1,800/day in his neighborhood, 8 days a year = $14,400 deducted by the S-corp, received tax-free by James personally. And his shop does fully custom cabinet design with CAD prototyping — PilePilot flagged ~$38K of labor cost as potentially R&D-qualifying, generating a $3,800 federal credit (plus PA state credit).
Year-one total tax savings: $43,260. James used the cash flow to put a 20% down payment on a second work truck instead of financing 100%.
Plain answers, grounded in the IRS code. No legalese.
Heavy trucks and SUVs over 6,000 lbs GVWR (most full-size work trucks, F-250s, Sprinter vans, Transits) qualify for §179 expensing up to $30,500 in 2026 plus bonus depreciation on the rest. Smaller pickups still qualify for §179 but with a lower cap. Track business-use percentage carefully — under 50% kills the deduction.
Anything you buy and consume on a job — drywall, lumber, fittings, paint, screws — is COGS or supplies. Tools (drills, saws, ladders, generators) are §179 / depreciable if over the de minimis threshold. PilePilot's contractor template separates tool purchases from materials automatically.
If they bring their own tools, set their own hours, work for multiple GCs, and you don't tell them how to do the job — 1099 is generally appropriate. If they're effectively your employee with daily direction, 1099 is risky. Misclassification penalties are steep. When in doubt, ask a qualified tax professional — and yes, PilePilot is built by one.
Once your net profit (after paying subs and materials) is around $80K, S-corp election starts saving real money on self-employment tax. Most established GCs and trades businesses with $300K+ revenue are leaving $8K–$20K a year on the table by staying a sole prop or single-member LLC. See the full breakdown →
Yes — if you're doing custom design-builds, prototyping new construction methods, testing materials, or developing proprietary processes (like a unique waterproofing system or a custom CNC fabrication workflow), portions of your labor cost can qualify. Not for cookie-cutter remodels, but for genuinely innovative work — and even kitchen-cabinet shops doing CAD work can qualify.
