General Contractor and Trades Taxes (2026)

If you run your own jobs — as a licensed general contractor, a remodeler, an electrician, a plumber, an HVAC tech, or any skilled trade billing customers directly under your own name or your own business entity — the IRS treats you as a self-employed contractor and your work goes on Schedule C. Builders, homeowners, and general contractors who hire you issue you a 1099-NEC at year end (when payments reach $600 from any single payer). There is no tax withheld from a customer's check or a builder's draw payment. You report gross revenue on Schedule C, subtract every legitimate job cost and overhead expense, and pay self-employment tax plus federal income tax on the net. This guide assumes you bill customers directly or run your own jobs as a 1099 contractor. If you are a W-2 employee of a single GC or large contractor, this is not your guide.

Trades are a high-revenue, high-cost business. Gross can look enormous because materials flow through the books — you bill $40,000 for a kitchen remodel, $18,000 of which is cabinets and tile you ordered and the homeowner reimbursed. That $18,000 is income on Schedule C line 1 (or in COGS, depending on accounting style), and it is also a deduction. Net profit is what is left after materials, subcontractor labor, equipment, insurance, bonding, and overhead. A typical small GC running 12 to 24 jobs a year grosses $200,000 to $400,000 and nets $50,000 to $120,000. The deductions are concentrated in a few buckets — materials, sub labor, the work truck, business insurance, and tools — and getting those right is the difference between a respectable tax bill and a punishing one.

Because nobody withholds tax from a customer check or a builder draw, the IRS expects you to pay quarterly estimated payments. If you expect to owe $1,000 or more for the year, estimates are due April 15, June 16, September 15, and January 15, 2027. Contractors are notorious for spending the deposit money before realizing it has to cover materials, sub labor, and taxes — a workable discipline is to move 18 to 25 percent of every customer payment into a dedicated tax account on the day it arrives, and cut quarterly checks from there. Lower-end of that range if material pass-through is high (because gross overstates real earning power); higher end if you run lean overhead. This guide walks through the forms, the deductions specific to trades work, a worked $245,000-gross example, and the questions contractors ask most often.

Income context

Independent contractors typically receive a 1099-NEC from every builder, GC, property manager, or homeowner who paid you $600 or more during the year and issued one (homeowners often do not issue 1099s even when required, but builders and commercial customers almost always do). For 2026, the 1099-K threshold per payment network is $2,500 — meaningful for trades who get paid through Venmo Business, HomeAdvisor / Angi, Thumbtack, or any platform that routes payments through a third-party processor. Where you receive both a 1099-NEC from the customer and a 1099-K from the payment platform covering the same revenue, report the gross once on Schedule C and document the overlap in work papers. Cash payments and checks are also reportable income even if no 1099 is issued — the absence of a 1099 does not change the income's taxability, only the IRS's automated matching capability.

Material pass-through is the trickiest income-reporting wrinkle for trades. If a homeowner pays you $40,000 for a kitchen remodel and you spent $18,000 on cabinets, tile, and appliances, the entire $40,000 is Schedule C revenue and the $18,000 is a deductible cost — not a $22,000 net revenue line. Some contractors report only the net (the labor portion) on Schedule C and treat materials as a pass-through; that approach can work cleanly if and only if the materials were invoiced and paid directly by the homeowner with the contractor never taking title — but if the contractor wrote the check at the supply house and got reimbursed, the gross-and-deduct approach is the correct treatment. Misreporting causes immediate problems if the homeowner takes a tax credit (energy-efficient appliance credit, residential clean-energy credit) based on receipts that include amounts the contractor did not report as gross.

Which 1099 forms you'll see

Profession-specific deductions

Materials (lumber, cabinets, tile, fixtures, electrical, plumbing)

Materials are typically the single largest line on a trades Schedule C — often 35 to 55 percent of gross for a remodeling or new-construction operation. Lumber, framing materials, cabinets, tile, plumbing fixtures, electrical components, paint, drywall, insulation, finish hardware — anything that becomes part of the customer's project and is invoiced through to the customer is a deductible material cost. Account for materials either through Cost of Goods Sold (the inventory-style approach common when contractors carry meaningful stock) or through Supplies expense (the simpler approach when materials are bought job-by-job and used immediately). Both are correct; the IRS expects consistency, not a specific method. Track materials by job in your accounting so you can defend the deduction against the matching customer invoice. Gotcha: Materials you bought for a job but later returned to the supplier are a wash, not a deduction — the refund offsets the original purchase, net to zero. Materials sitting in inventory at year end (lumber on the shelf for next year's projects, cabinet pulls you stocked up on) are not deductible until used if you account through COGS; they are part of ending inventory. If you account through Supplies, year-end inventory is generally immaterial for tax purposes under the de minimis safe harbor — but stocking large amounts of materials right before year end and expensing them can attract scrutiny if it produces an artificially large loss. UNICAP rules under §263A do not apply to most small contractors — the small-business exemption under §263A(b)(2)(B) waives UNICAP for taxpayers with average annual gross receipts under the §448(c) threshold (approximately $30 million in 2026). (IRC §162; IRS Publication 535)

Tools and equipment (Section 179)

Hand tools (drills, saws, drivers, levels, measuring), power tools (miter saws, table saws, compressors, generators), specialty tools (pipe threaders, conduit benders, HVAC manifolds, tile saws), and ladders are deductible business property. Section 179 allows full expensing in the year of purchase up to the 2026 limit of $1.22 million — meaning a $3,500 set of new power tools is fully deductible the year you buy them rather than depreciated over five years. The election is made on Form 4562. Most trades buy enough tools each year (replacements for tools that die, additions for new specialties) that the Section 179 election produces a $3,000 to $10,000 annual deduction without any single large purchase. Gotcha: Business-use percentage matters. A tool used 50 percent or less for business does not qualify for Section 179 — you depreciate at the business-use percentage instead. A drill you also use for personal projects at home (hanging pictures, fixing the deck) is technically a mixed-use asset. Most contractors can defensibly claim 90 to 100 percent business use on professional tools given how much they get used on jobs, but be honest in the allocation. If you ever stop using a Section 179'd tool for business and convert it to personal use, recapture rules apply and you may owe tax in the year of conversion. (IRC §179; IRS Publication 946)

Heavy equipment rental (excavators, lifts, scaffolding)

Renting heavy equipment — mini-excavator for a foundation dig, articulating boom lift for a roof replacement, scaffolding for a multi-story exterior, concrete pump for a slab pour — is fully deductible as Schedule C equipment rental in the year incurred. Rental costs vary widely: a mini-ex from United Rentals runs $250 to $400 per day; a 40-foot boom lift runs $400 to $600 per day; concrete pumping is $1,500 to $3,000 for a typical residential slab. The rental company issues you an invoice and may issue a 1099-NEC if the rental company is structured to require one for above-threshold payments to a contractor account. Rental delivery and pickup charges are also deductible. Gotcha: Damage waivers and rental insurance on heavy equipment are deductible as part of the rental expense; physical damage to the equipment that you cover out of pocket (a broken arm on the excavator) is also deductible as a business loss. But fines paid for unsafe operation, equipment damage from negligent use that the rental company's insurance excludes, or fines from a job-site inspector for using equipment without required certifications are not deductible under IRC §162(f). Section 179 does not apply to rentals — only to purchased equipment you own. (IRC §162; IRC §162(f); IRS Publication 535)

Subcontractor labor (1099-NEC issued by you)

Subcontractor labor is often the second-largest line on a small-GC Schedule C — paying an electrician $4,500 to wire a remodel, a tile setter $3,200 to lay 800 square feet, an HVAC contractor $6,000 to install a new system. Each subcontractor paid $600 or more during the year requires you to collect a W-9 before paying them and issue them a 1099-NEC by January 31 of the following year. The IRS penalty for failure to file a required 1099 is $290 per missed form (2026 rate) and $580 per form if intentional disregard. Subcontractor labor is deductible on Schedule C line 11 (Contract labor) — do not bury it in Other Expenses. Gotcha: Misclassifying a worker as a 1099 subcontractor when they really function as your employee is the single highest-audit-risk pattern for small contractors. A genuine sub runs their own business, sets their own hours, supplies their own tools, and could refuse a job. A 'sub' who shows up every day at the same time, uses your tools, takes direction from you on how to do the work, and works only for you is probably an employee under IRS and DOL classification tests (Treas. Reg. §31.3401(c)-1, Rev. Rul. 87-41 twenty-factor test). Misclassification penalties include back payroll taxes, interest, and worker-related penalties. If you have a regular helper who shows up daily and works only for you, payroll and W-2 is the safer path even though it costs more than 1099. (IRC §3121; IRC §3401; Rev. Rul. 87-41; Treas. Reg. §31.3401(c)-1)

Work truck — actual expenses with Section 179 or bonus depreciation

For most contractors with a dedicated work truck, the actual-expense method beats the standard mileage rate. A $60,000 heavy-duty pickup with a service body, used 90 percent for business, generates a Section 179 expense plus actual fuel, insurance, repairs, and tires — typically $25,000 to $40,000 in first-year deductions versus the standard mileage rate of $0.725 per mile on 15,000 miles ($10,875). The 6,000-pound gross vehicle weight rating (GVWR) is the key threshold — trucks above 6,000 lbs qualify for full Section 179 up to the SUV cap ($31,300 in 2026, indexed annually — the SUV Section 179 cap is adjusted for inflation annually; verify the current limit before filing), and trucks with cargo beds longer than six feet generally qualify for unrestricted Section 179 above that cap. Tradition has it that the Ford F-250 / Ram 2500 / Chevy 2500 class is the sweet spot for Section 179 contractors. Gotcha: Once you elect actual expenses on a vehicle, you cannot switch to standard mileage in a later year for that same vehicle — locked in for the life of ownership. Business-use percentage matters: a truck used 60 percent for business gets 60 percent of the Section 179 deduction and 60 percent of the operating costs. If business use drops below 50 percent in a later year, Section 179 is partially recaptured as ordinary income. Personal use of a work truck (running family errands, hauling personal furniture, driving to the lake) reduces business-use percentage. Be honest in the allocation; a 100 percent business claim on a pickup that obviously sees personal use is indefensible. (IRC §179; IRC §168(k); IRS Publication 946)

Business insurance (general liability, workers comp, commercial auto)

Trades carry a stack of insurance: general liability ($1 million / $2 million typical, premium $700 to $3,000 per year depending on trade and revenue), workers compensation (required in most states if you have employees, optional but often required by GCs for sole proprietors, $800 to $4,000 per year), commercial auto on the work truck ($1,500 to $4,000 per year), inland marine for tools and equipment in the truck ($300 to $1,000), and trade-specific coverages like a contractor's bond. Total annual insurance for an active small contractor runs $3,000 to $10,000 and is fully deductible on Schedule C as insurance expense. Itemize by category in your bookkeeping so you can defend the mix on audit. Gotcha: Personal auto insurance on a daily-driver pickup is not deductible on Schedule C even if you sometimes use the truck for work — that is a mixed-use vehicle requiring allocation, not pure business insurance. Homeowner's insurance that includes a business-use endorsement covering tool storage at home or the home office is partially deductible as the business-use portion, but the underlying personal homeowner premium is not. Some insurance products bundle personal and business coverage (a personal umbrella with commercial extension) — split the premium per the carrier's allocation, not by guesswork. (IRC §162; IRS Publication 535)

License renewals and trade-specific certifications

Trade licenses required by your state to perform the work — electrical journeyman or master license, plumbing license, HVAC mechanical license, general contractor license, and local business licenses — all carry annual or biennial renewal fees ($100 to $500 per cycle). Continuing-education hours required to maintain the license are also deductible. The cost of a course that maintains or improves your skills in your current trade qualifies; the cost of a course that qualifies you for a new trade does not. Gotcha: Initial licensing — courses, exams, and fees to obtain a license you do not yet hold — falls under IRC §195 startup costs or is non-deductible personal education depending on whether the new license expands your existing trade or starts a new one. An electrician taking a master-electrician upgrade course is improving skills in the current trade (deductible); an electrician taking a journeyman-plumbing course is training for a new trade (not deductible until the new trade is operational, then potentially §195 startup costs). The line is fact-specific; for borderline cases, get a preparer's opinion. (IRC §162; IRC §195; Treas. Reg. §1.162-5)

Bonding (performance bonds, surety bonds, license bonds)

Many states require contractors to post a license bond (typically $5,000 to $25,000 face value, premium 1 to 3 percent of face value annually for a clean credit profile) before issuing a contractor license. Performance bonds on specific jobs (typically required on public-works projects, sometimes on large private commercial jobs) run 1 to 3 percent of the bond face value as premium. Payment bonds (guaranteeing payment to subs and suppliers) run similarly. All bond premiums are deductible Schedule C insurance expense in the year incurred. The bond protects the customer or the state, not the contractor — if a claim is paid out, the contractor owes the bond company. Gotcha: A claim paid out from a bond and recovered from the contractor is generally a deductible business loss in the year the contractor reimburses the bond company — but the underlying act (failure to complete a job, failure to pay a sub) is also a sign of business distress that needs to be addressed separately. Bond renewal premiums are straightforward Schedule C deductions; bond claim repayments require careful accounting to distinguish the deductible loss from any settlement or legal-fee components. (IRC §162; IRS Publication 535)

Job-site supplies, PPE, dumpsters, and porta-johns

Job-site supplies that are not part of the permanent installation — PPE (hard hats, gloves, safety glasses, hearing protection, fall-arrest harnesses), tarps, plastic sheeting, blue painter's tape, drop cloths, vacuum bags for the shop vac — are deductible as supplies in the year purchased. Job-site dumpsters ($400 to $700 per pull for a residential remodel) and porta-johns ($150 to $300 per month) are deductible as job costs. These are typically per-job expenses, billed to the customer as part of the project price; you deduct them on Schedule C and the customer's payment covers them as part of gross revenue. Gotcha: Dumpsters and porta-johns are job-site services, not supplies — split them properly in your accounting (supplies vs. equipment rental vs. job costs) so the deductions don't all pile up in a single bucket that looks abnormally large. PPE you also use for personal projects (a respirator you wear when refinishing your own kitchen) needs allocation; most contractors can defensibly claim 90 to 100 percent business use given how often PPE gets used on jobs. (IRC §162; IRS Publication 535)

Office at home plus project-management software

Contractors who run their estimating, scheduling, and customer communication from home maintain a home office subject to the IRS Publication 587 rules. A dedicated home office used exclusively and regularly for the business — desk, laptop, plan-review space, filing — qualifies for either the simplified method ($5 per square foot, capped at 300 sq ft and $1,500 a year) or actual expenses. Contractors typically benefit more from the actual-expense method given the larger square footage often needed for plan review. Project-management software (Buildertrend $400 to $700 per month, JobNimbus $40 to $200 per month, CompanyCam $20 to $50 per month per user, QuickBooks Online $30 to $200 per month) is deductible separately as Schedule C software expense. Gotcha: Exclusive use is exclusive. A desk in the family room where you also help the kids with homework does not qualify even if you do most of your bookkeeping there. A dedicated office or a partitioned area used only for the contracting business qualifies. The truck itself is not a home office for tax purposes — even if you do most of your customer communication from the truck cab, the home-office deduction is anchored to a portion of your principal residence under §280A, not to the truck. (IRC §280A; IRS Publication 587)

Phone (dedicated business line ideal) and communications

Trades live on the phone — customer calls, supplier orders, sub coordination, scheduling. The business-use percentage of a personal cell plan is deductible on Schedule C. A separate dedicated business phone (RingCentral, Grasshopper, or a second cell line) goes fully on Schedule C as a 100 percent business cost — the cleanest substantiation. A dedicated work line also produces cleaner customer-call records for warranty and dispute claims. Phone hardware is Section 179 expensable in the year purchased. Voicemail-to-text services, Google Workspace business email, and customer-CRM phone integrations are also deductible. Gotcha: Claiming 100 percent business use of your only smartphone is indefensible without a separate dedicated business line — the IRS will assume some personal use of an only phone. A second cell line on a family plan (an additional line dedicated to the business) at $30 to $50 a month is the cleanest path to a 100 percent business phone deduction. Cheaper than a separate carrier and produces clean monthly statements identifying the business line specifically. (IRC §162; IRC §179; IRS Publication 535)

Continuing education and code updates

Code update courses (NEC, IPC, IMC, IRC adoption cycles vary by state), OSHA 10 or 30 hour, EPA Section 608 refrigerant handling and recertification, EPA RRP lead-safe renovation certification and renewal, electrical code update courses, trade-specific specialty courses (geothermal HVAC, low-voltage systems, advanced solar installation) are all deductible CE in the year completed. Many states require periodic code-update hours to renew the trade license — those hours are unambiguously deductible. Trade-organization memberships (NAHB / HBA, NECA, ABC) and conference fees (the annual IBSx International Builders' Show, NAHB national, regional trade shows) are also deductible CE-adjacent business expenses. Gotcha: Education that qualifies you for a new trade is not deductible from your current trade's Schedule C — an electrician taking a journeyman-plumbing course is in a different lane. Travel and lodging at trade conferences are deductible only when business is the primary purpose of the trip; a four-day trade show with one day of business meetings and three days of vacation is mostly personal travel with a small business component. The IRS travel-expense rules under IRC §274 apply. (IRC §162; IRC §274; Treas. Reg. §1.162-5)

Worked example: small GC grossing $245,000 with heavy material and sub-labor pass-through

Consider a single-filing small general contractor who grosses $245,000 in 2026 across 14 jobs (mix of kitchen remodels, bathroom renovations, two additions, and a few smaller repairs). Total deductions run about $172,000: $98,000 in materials (cabinets, tile, lumber, fixtures, finish hardware passed through to customers), $42,000 in subcontractor labor (electrical, plumbing, drywall, tile setters — all properly 1099'd at year end), $12,000 in work-truck actual expenses (fuel, insurance, repairs, partial-year Section 179 on a new work truck), $7,500 in business insurance (general liability, workers comp, commercial auto), $4,500 in tools and equipment rental, $3,200 in job-site supplies and dumpsters, $2,800 in license renewals and bonding, and $2,000 in software, phone, and office overhead. Net Schedule C profit is $245,000 minus $172,000, or $73,000.

Self-employment tax is calculated on 92.35 percent of net self-employment earnings — that is the statutory adjustment that mirrors the deductible employer-share of FICA. The SE tax base is $73,000 times 0.9235, or $67,416. SE tax at the full 15.3 percent rate (well below the $184,500 Social Security wage base) is $10,315. Half of that ($5,158) is deductible above-the-line on Schedule 1, bringing adjusted gross income to $67,842. The 2026 QBI deduction at 20 percent of net earnings after the half-SE adjustment is $13,568 — construction and trades are not specified service trades or businesses (SSTBs) under §199A, so the full QBI applies cleanly even as income scales. Above the $201,750 single threshold, contractors face W-2 wage and UBIA-of-qualified-property limitations on QBI rather than the SSTB phaseout that hits agents and notaries.

After subtracting the 2026 single standard deduction of $16,100 and the $13,568 QBI deduction from AGI, taxable income lands at $38,174 — partly in the 10 percent bracket, partly in the 12 percent bracket. Federal income tax on $38,174 is approximately $4,333. Total federal tax (SE tax plus income tax) is $10,315 plus $4,333, or $14,648. Divided by the original $245,000 gross, the effective all-in federal rate is approximately 6.0 percent. The headline lesson for contractors: the gross-versus-net gap is wide because material and sub-labor pass-through inflates gross — the effective rate looks low against gross but is meaningful against net. Set aside 20 to 25 percent of every customer payment for taxes, issue 1099-NECs to every sub paid $600 or more, and reconcile material costs to customer invoices job-by-job so you can defend the deductions on audit.

FAQ

When does it make sense for a contractor to elect S-corporation taxation?

S-corp election starts to make sense when net Schedule C profit is reliably above $80,000 to $100,000 a year and you have predictable income. As a sole proprietor, every dollar of net SE income up to the $184,500 Social Security wage base is hit by the full 15.3 percent SE tax, then 2.9 percent above. As an S-corp owner-employee, you pay yourself a reasonable W-2 salary subject to payroll tax, but distributions above that salary are not subject to SE or payroll tax. On $120,000 of net contracting profit with a $65,000 reasonable salary, the S-corp typically saves $6,000 to $9,000 a year in payroll tax versus a sole prop, net of $2,000 to $4,000 in extra payroll and tax-prep fees. Under $70,000 of net profit, the payroll overhead and reasonable-compensation requirement usually eat the savings. Reasonable compensation is the IRS audit hotspot for contractor S-corps — the W-2 salary needs to look reasonable for the work performed; setting it artificially low to maximize distributions is the most common S-corp error. Get a CPA opinion before electing; a botched S-corp can be more expensive than the sole prop it replaced.

Do I have to issue 1099-NECs to my subcontractors, and what happens if I don't?

Yes — if you paid any subcontractor $600 or more during the year for services in the course of your trade or business, you must issue them a 1099-NEC by January 31 of the following year and file copies with the IRS. The 2026 penalty for failure to file a required 1099 is $290 per missed form (rising to $580 per form if the IRS deems intentional disregard). You must also collect a W-9 from the sub before paying them — the W-9 establishes the sub's taxpayer ID and exempt-from-backup-withholding status. Failing to collect a W-9 means you should withhold 24 percent backup-withholding from the payment and remit it to the IRS; almost no contractors do this, which is why the W-9-first practice is the cleaner solution. Beyond the per-form penalties, undocumented payments to subs are a high-audit-risk pattern that can trigger both 1099 penalties and worker-classification scrutiny. Treat subcontractor payments and 1099 issuance as a single bundled discipline: W-9 in before the first payment goes out, 1099 out by January 31.

Cash or accrual accounting for a material-heavy contracting business?

Cash accounting is generally simpler and is allowed for contractors with average annual gross receipts under $30 million (2026 inflation-adjusted threshold under §448). Cash basis means you recognize revenue when the customer pays and expenses when you pay — straightforward and easy to track. Accrual basis recognizes revenue when earned and expenses when incurred regardless of cash timing. For material-heavy contractors, accrual basis can produce a more accurate picture of profitability on long jobs that span the year-end boundary — you bought materials in December for a January-completion job, billed and received payment in January; cash basis puts the deduction in December and the revenue in January (creating an artificial December loss), while accrual matches them up. Most small contractors use cash basis because it's simpler and works fine for jobs that complete within a few months. Long-term construction contracts (jobs that span more than one tax year) have additional rules under IRC §460 — percentage-of-completion or completed-contract methods may apply depending on the contract type and the contractor's size. Talk to a preparer if you regularly run jobs that cross year-end.

Is mobilization travel — driving from home to a remote job site — deductible?

Travel between a regular work location and a job site is generally deductible business mileage. Travel between your home and a regular work location is commuting and not deductible. For most small contractors, the home is the principal place of business (where the office is, where supplies are stored, where bidding and customer communication happens), so trips from home to a job site qualify as business mileage. Out-of-town jobs that require overnight stays (a multi-day project two hours from home where you stay in a hotel) generate deductible travel — mileage to and from, lodging at the destination, and meals at 50 percent. If a job is within commuting distance of your principal place of business, the trip is commuting and not separately deductible (already captured in the daily commute pattern). The audit question is whether the home is genuinely the principal place of business; a contractor who runs from a separate office or shop has a different mileage profile and the home-to-shop trip is commute.

What's the riskiest part of classifying my workers as subcontractors versus employees?

The riskiest pattern is a 'sub' who functions as an employee in every respect except the 1099 form at year end. The IRS classification tests under Rev. Rul. 87-41 and the common-law agency rules focus on three categories: behavioral control (does the worker decide how to do the work, or do you direct it?), financial control (does the worker bear financial risk, have other clients, set their own rates?), and the relationship (is it ongoing or project-by-project, are there written contracts, do you provide benefits?). A regular helper who shows up to your shop every morning, uses your tools, takes direction from you on every task, works only for you, and gets paid weekly is almost certainly an employee even if you cut a check labeled '1099 sub.' Misclassification consequences include: back payroll taxes (employer's share of FICA, FUTA, state unemployment), interest on those amounts, IRC §3509 penalties (which can convert a small underpayment into a large bill), and potential exposure to back overtime under the Fair Labor Standards Act. The DOL has been increasing misclassification enforcement; state labor departments often coordinate with the IRS. If you have a regular daily helper, payroll and W-2 is the safer path even though it costs 20 to 30 percent more in payroll taxes than a 1099 arrangement — the alternative is a much larger bill if the IRS or DOL reclassifies them after the fact.
