Why Construction Needs a Specialist CPA

Construction is one of the few industries where standard accounting rules must be significantly adapted. A general contractor managing four open jobs at once cannot run their books like a retail store or consulting firm. Each job has different owners, subcontractors, completion timelines, and retainage terms. The revenue recognition methods, cost allocation systems, and financial statement formats used in construction are purpose-built for the industry's project-based structure.

Five tax and accounting rules apply uniquely to construction businesses:

• Percentage-of-completion accounting required by IRC §460 for most long-term contracts spanning more than one tax year.
• WIP (Work-in-Progress) schedules reconciling earned revenue, billed amounts, and over-/under-billings every period — required by sureties and lenders.
• NJ prevailing wage compliance on public-works contracts with payroll documentation requirements separate from federal wage rules.
• Subcontractor 1099-NEC management with TIN verification at vendor onboarding to avoid year-end scrambling.
• Equipment depreciation under Section 179 + bonus depreciation, often paired with cost segregation when contractors own real estate.

ProAxis serves general contractors, specialty subcontractors, residential builders, and home-improvement contractors across NJ, NY, and PA. Each engagement starts with a review of the current chart of accounts, WIP schedule, and subcontractor process. Contractor onboarding often surfaces missed deductions or job costs booked to the wrong account. Results vary by contract mix, prior bookkeeping quality, and entity type — past engagement outcomes do not guarantee future ones.

Where Contractors Most Commonly Save Tax

Most contractors walk in with a tax return that misses the levers built into the code for project-based businesses. A specialist CPA looks at six places first.

• S-Corp election for contractors clearing roughly $60,000 in net profit. The election splits income between a reasonable W-2 salary and a distribution, and self-employment tax is saved on the distribution portion. Run the math on real numbers with the S-Corp savings calculator.
• Section 179 and bonus depreciation on equipment — trucks, trailers, excavators, tools, and qualifying software placed in service during the year. Heavy equipment routinely hits the Section 179 cap.
• QBI deduction (Section 199A) — a 20% deduction on qualified business income for pass-through entities. Most contractor LLCs and S-Corps qualify when taxable income sits under the annual threshold.
• NJ BAIT election for entity-level pass-through tax that bypasses the federal SALT cap. Useful for multi-member contractor entities whose NJ state tax exceeds the cap. ProAxis runs the NJ BAIT savings calculator before electing.
• Cost segregation when a contractor owns the shop, yard, or rental property used in the business. Reclassifying portions of the building into shorter-life property accelerates depreciation in the early years.
• Accountable plan reimbursements for fuel, tools, phones, and vehicle mileage. Without a written plan, the same payments are taxable wages instead of tax-free reimbursements.

These are review points a specialist runs through during onboarding, not stacked promises. Whether any apply depends on the contractor's entity type, net profit, equipment spend, and trade mix. Results vary.

What to Expect from a Specialist Contractor CPA Engagement

A standard onboarding starts with a free consultation. The contractor shares prior-year returns, the open-job list, and a sample WIP schedule if one exists. ProAxis reviews entity structure, job-cost setup, subcontractor 1099 process, and whether the prior books reconciled retainage and over-/under-billings correctly.

From there, a monthly engagement covers the recurring work: job-cost coding on every transaction, WIP updates each period, vendor 1099 tracking with TIN verification, federal 941 and NJ-927 payroll filings, prevailing-wage certifications when applicable, and clean monthly financials per job and in total. Tax planning runs in the background — quarterly estimate review, mid-year strategy check, and a year-end position review before the return is filed.

Contractors who arrive with messy prior books usually need a separate cleanup project before regular monthly work begins. ProAxis quotes that as a fixed-fee scope so the owner can decide whether to clean up a partial year or restate the prior tax return as well. The choice is driven by the size of the issue, not by a default playbook.

Common Contractor Bookkeeping Pitfalls

Most monthly books that arrive on review have one or more of the following errors. Each one quietly distorts the tax return, the per-job margin, and the numbers the contractor uses to bid the next job.

• No job in the transaction. Costs coded to "Materials" or "Subcontractors" without a Job or Customer assigned end up in a single bucket. Per-job profit becomes impossible to measure, and the WIP schedule cannot be built.
• Retainage booked as revenue too early. Retainage withheld by the owner is earned but not yet billable. Booking it in current revenue inflates the top line and distorts margin until the job closes.
• Change orders never re-baselined. When a change order is approved but the contract value in the books is not updated, every WIP calculation for that job is wrong. Over- and under-billings drift from real exposure.
• Subcontractor payments without a W-9 on file. Year-end 1099-NEC prep turns into a scramble for tax IDs that should have been collected at onboarding. Missing TINs trigger IRS backup-withholding rules.
• Equipment expensed in full when it should be depreciated. A skid steer booked to "Repairs and Maintenance" hides a fixed asset that belongs on the depreciation schedule. The tax return misses Section 179 or bonus depreciation, and the balance sheet understates real equity.
