A Contractor’s Guide to Getting It Right
Choosing the right construction accounting methods determines how accurately you track profitability across projects. Unlike retail or service businesses, contractors must match revenue to specific jobs over extended timelines. This makes method selection a strategic decision — not just a compliance checkbox.
TYS Advisors help contractors across United States, implement the accounting methods that minimize tax liability while keeping bonding companies satisfied. With over 60 years of combined construction accounting experience, we’ve seen firsthand how the wrong method creates costly problems.

The Three Primary Construction Accounting Methods
1. Percentage of Completion Method (PCM)
The Percentage of Completion Method recognizes revenue based on how much work you’ve finished. For example, if a $2 million project is 35% complete, you report $700,000 in revenue. The IRS requires this method under Section 460 for most contracts exceeding two years.
PCM provides the most accurate financial picture at any point during a project. Bonding companies prefer it because it reflects real economic activity. However, it demands rigorous cost tracking. Every labor hour, material purchase, and subcontractor invoice must connect to a specific job and cost code.
Most importantly, PCM ties your tax liability to project progress. Overstating completion accelerates taxes owed. Understating it creates compliance risk during audits. Therefore, accurate progress estimates are essential.
2. Completed Contract Method (CCM)

The Completed Contract Method defers all revenue recognition until a project finishes. This approach benefits smaller contractors who qualify under the IRS gross receipts threshold (currently $29 million averaged over three years).
CCM simplifies reporting because you don’t need to estimate completion percentages. Additionally, it can defer tax liability to future periods. However, bonding companies often view CCM financial statements with skepticism. Your balance sheet may not reflect your true financial position during active projects.
Contractors using CCM should understand the trade-off clearly. You gain simplicity and potential tax deferral. In return, you sacrifice financial transparency on active work.
3. Cash Basis Accounting
Cash basis accounting records revenue when you receive payment and expenses when you pay bills. It’s the simplest method available. Small contractors and specialty trades often start here because it requires minimal accounting infrastructure.
However, cash basis has significant limitations for growing contractors. It doesn’t match costs to specific projects. As a result, you cannot determine individual job profitability. Furthermore, bonding companies and banks rarely accept cash-basis financial statements for surety or credit decisions.
Understanding Construction Expenses Accounting
Regardless of which method you choose, construction expenses accounting requires project-level detail that general bookkeeping cannot provide. Every expense falls into one of several categories that affect your job cost reports and financial statements differently.
Direct costs include labor, materials, equipment rental, and subcontractor payments tied to specific jobs. These costs flow directly to individual project budgets. Indirect costs — like insurance, office rent, and administrative salaries — must be allocated across projects using a consistent methodology.
Construction cost accounting also requires tracking committed costs. When you sign a subcontract or material purchase order, those committed dollars affect your projected job profitability. Ignoring commitments leads to nasty surprises at project completion.
How to Choose the Right Method
Several factors determine which construction accounting method fits your business:
- Annual gross receipts — Contractors above $29 million must use PCM for long-term contracts.
- Contract duration — Short-term projects (under 12 months) offer more flexibility in method selection.
- Bonding requirements — If you need surety bonds, PCM provides the financial transparency bonding companies expect.
- Tax planning goals — CCM may defer taxes, but PCM spreads liability more evenly across project timelines.
- Growth trajectory — Contractors planning rapid growth should adopt PCM early to avoid costly method changes later.
TYS Advisors evaluates each contractor’s unique situation before recommending a method. In many cases, we find that contractors are using the wrong method — either leaving tax savings on the table or creating compliance exposure.
Frequently Asked Questions
Q: What are the main construction accounting methods?
A: The three primary methods are the Percentage of Completion Method (PCM), the Completed Contract Method (CCM), and cash basis accounting. PCM recognizes revenue as work progresses and is required by the IRS under Section 460 for most large contracts. CCM defers revenue until project completion, while cash basis records income when payment is received.
Q: How does construction expenses accounting differ from standard expense tracking?
A: Construction expenses accounting tracks every cost at the project level, connecting labor, materials, equipment, and subcontractor payments to specific jobs and cost codes. Standard expense tracking only categorizes costs by type or department. This project-level detail is essential for determining individual job profitability, preparing WIP schedules, and satisfying bonding company requirements.
Q: Why do bonding companies prefer the Percentage of Completion Method?
A: Bonding companies prefer PCM because it shows the contractor’s real financial position on active projects. Under the Completed Contract Method, revenue and profit remain hidden until projects finish. PCM-based WIP schedules reveal overbillings, underbillings, and projected margins — giving surety underwriters the transparency they need to assess risk accurately.
Q: When should a construction company switch accounting methods?
A: Consider switching methods when your gross receipts approach the IRS threshold ($29 million average), when bonding companies request PCM-based statements, or when your current method no longer reflects your true financial position. Method changes require IRS approval through Form 3115. TYS manages this process regularly for growing contractors.
