Percentage of Completion Accounting for Contractors
A deep dive into the Percentage of Completion (PoC) method for construction revenue recognition. Learn how to maintain ASC 606 compliance and calculate WIP correctly.
The Percentage of Completion (PoC) method is an accounting practice where revenue and expenses from long-term contracts are recognized progressively based on the stage of completion. Unlike the completed contract method, PoC allows contractors to match revenue with the actual work performed during a specific period. Under ASC 606, this is typically measured by the 'cost-to-cost' method, which compares costs incurred to date against total estimated project costs. Accurate PoC accounting is essential for maintaining WIP (Work in Progress) reports and ensuring financial statements reflect true profitability.Quick Answer: What is Percentage of Completion (PoC)?
Introduction to PoC in Modern Construction
For construction firms, financial clarity is often obscured by the long-tail nature of projects. A project started in October may not finish until the following August, creating a dilemma: when do you recognize the 'win'? In the world of construction finance, the Percentage of Completion (PoC) method is the gold standard for answering this question. It provides a real-time snapshot of financial health, satisfies lenders, and ensures compliance with the Financial Accounting Standards Board (FASB).
As experts in job costing for contractors, Scaffold Bookkeeping understands that PoC is more than just a formula—it is the backbone of your balance sheet. This guide explores the technical nuances of ASC 606, IRS thresholds, and practical calculations to keep your bookkeeping audit-ready.
The Shift to ASC 606: Revenue from Contracts with Customers
The implementation of ASC 606 fundamentally changed how contractors view revenue. While the term 'Percentage of Completion' is still widely used in the field, the GAAP (Generally Accepted Accounting Principles) framework now refers to this as 'Revenue Recognition Over Time.'
The Five-Step Model
To apply PoC under ASC 606, contractors must follow five specific steps:
- Identify the contract: Highlighting the obligations between the contractor and the client.
- Identify performance obligations: Determining if a project is one large obligation or several distinct ones (e.g., design vs. build).
- Determine the transaction price: The total expected revenue, including change order management considerations.
- Allocate the price: Assigning revenue to each performance obligation.
- Recognize revenue: Recording revenue as (or when) the contractor satisfies the performance obligation.
For most contractors, the 'Over Time' recognition is triggered because the customer controls the asset as it is being created (e.g., a building on the client’s land) or the contractor is creating a specialized asset with no alternative use and has a right to payment for work performed.
How to Calculate Percentage of Completion: The Cost-to-Cost Method
The most common and accurate way to measure progress is the Cost-to-Cost Method. This formula relies on your WIP reports and accurate job costing.
The Formula:
Step 1: Determine Percentage Complete
(Actual Costs Incurred to Date) / (Total Estimated Costs at Completion) = % Complete
Step 2: Calculate Earned Revenue
(% Complete) x (Total Contract Price) = Revenue to Recognize
Practical Example:
Imagine a $1,000,000 commercial renovation project. Your initial estimate for total costs is $800,000.
- At the end of Q1, you have incurred $200,000 in costs.
- Calculation: $200,000 / $800,000 = 25% complete.
- Revenue Recognized: 25% of $1,000,000 = $250,000.
If you have only billed the client $200,000 at this stage, you are under-billed by $50,000. This is an asset on your balance sheet because you have earned the money but haven't invoiced it yet. Conversely, if you billed $300,000, you are over-billed (a liability). Understanding these gaps in over/under billing is critical for cash flow management.
IRS Requirements and Tax Implications
While GAAP requires PoC for many financial statements, the IRS has its own set of rules regarding which contractors must use it for tax purposes and who can opt for the Completed Contract Method (CCM).
The Small Contractor Exception
Under the Tax Cuts and Jobs Act (TCJA), contractors with average annual gross receipts of $29 million or less (adjusted for inflation) for the three prior years are generally exempt from the requirement to use PoC for long-term construction contracts. These 'small contractors' can use the CCM, which allows them to defer taxes until the project is finalized. However, even if you qualify for CCM for taxes, your bank or bonding agent will likely require PoC-based financial statements to assess your creditworthiness.
Large Contracts
For contractors exceeding the $29 million threshold, PoC is mandatory for the majority of long-term contracts. Furthermore, the IRS requires the Look-Back Rule (Form 8697), which forces contractors to recalculate their tax liability based on actual final costs rather than the estimates used during the project. If you underestimated profits, you may owe interest to the IRS; if you overestimated, you may receive a refund.
Integrating PoC with Job Costing and WIP
PoC is only as accurate as the data feeding it. If your field team isn't reporting labor hours or material deliveries accurately, your percentage of completion will be skewed. This is where WIP reporting becomes the essential tool.
A robust WIP report includes:
- Contract Amount (Revised for change orders)
- Estimated Total Costs
- Total Costs to Date
- Percentage Complete
- Earned Revenue
- Actual Billings
- Over/Under Billed amounts
- Projected Profit/Loss
At Scaffold Bookkeeping, we help contractors set up their QuickBooks for construction to automate these calculations, ensuring that the 'Total Estimated Costs' are reviewed monthly by project managers to account for price fluctuations in materials or labor shortages.
The Risks of Inaccurate PoC Accounting
Inaccurate estimates are the primary danger of the PoC method. There are two main types of errors:
- Profit Fade: When a project looks profitable early on, but as costs rise toward the end, the profit margin 'fades.' This often results from underestimating the final 'punch list' phase.
- Front-Loading: Aggressive revenue recognition early in a project to make financial statements look better. This can lead to a 'cash crunch' later in the project when costs continue but revenue has already been 'spent' on the books.
To mitigate these risks, contractors should utilize AIA billing standards, which provide a structured Schedule of Values that aligns well with PoC progress tracking.
Conclusion: Why Professional Bookkeeping Matters
Managing the Percentage of Completion method requires a sophisticated understanding of both construction operations and technical accounting standards. Transitioning from simple cash-flow tracking to full PoC/WIP reporting is often the catalyst that allows a subcontractor to become a prime contractor. It builds trust with sureties, provides clarity for owners, and ensures that tax seasons are stress-free.
Scaffold Bookkeeping specializes in navigating these complexities. Whether you are dealing with Washington State B&O taxes or trying to reconcile your over/under billings, our team provides the specialized oversight your construction business deserves.
Frequently Asked Questions
What is the difference between PoC and Completed Contract Method?
PoC recognizes revenue and expenses incrementally as work progresses, whereas the Completed Contract Method (CCM) defers all revenue and expense recognition until the project is 100% finished. CCM is generally only used by smaller contractors for tax purposes, while PoC is required by GAAP for most construction firms.
How does ASC 606 affect construction contracts?
ASC 606 shifted the focus to 'performance obligations' and 'transfer of control.' For contractors, this means revenue is recognized as they satisfy their obligation to the customer, usually measured by the cost-to-cost method. Scaffold Bookkeeping ensures your contracts are structured to comply with these FASB standards.
What is the 'Cost-to-Cost' method in construction?
It is the most common way to calculate the percentage of completion. It involves dividing the actual costs incurred to date by the total estimated costs of the project. This percentage is then applied to the total contract price to determine earned revenue.
Why do bonding companies require PoC financial statements?
Bonding companies use PoC statements because they provide a much more accurate view of a contractor's ongoing financial obligations and profitability. It reveals whether a contractor is over-billing (using future project funds for current expenses) or under-billing (leaving cash on the table).
Is a WIP report required for small contractors?
While contractors with average annual gross receipts under $25 million may be exempt from certain IRS requirements for the Percentage of Completion Method, they are still generally required to use it if they have audited financial statements or require bonding (Source: 26 USC §460(e)).
How often should a WIP report be updated?
To comply with accurate financial reporting standards and provide timely data for management, a WIP report should ideally be updated monthly to coincide with the closing of the books (Source: FASB ASC 606).
What is the 'Cost-to-Cost' method in a WIP report?
The cost-to-cost method is a way to determine the percentage of completion by comparing total costs incurred to date against total estimated costs for the project (Source: 26 USC §460(b)(1)).
What is What Is WIP Reporting in Construction & Why It Matters?
What Is WIP Reporting in Construction & Why It Matters is a critical financial process in construction that helps contractors track costs, ensure compliance, and maintain profitability across projects. It requires specialized knowledge of construction accounting principles and regulatory requirements.
Why is What Is WIP Reporting in Construction & Why It Matters important for construction companies?
What Is WIP Reporting in Construction & Why It Matters ensures accurate financial reporting, regulatory compliance with IRS and state requirements, and provides the data needed for informed business decisions. Without proper management, contractors risk financial penalties and lost profitability.
What is the primary difference between over-billing and under-billing in construction?
Over-billing occurs when a contractor invoices more than the earned revenue based on the percentage of completion. In contrast, under-billing happens when a contractor has incurred more costs or performed more work than they have invoiced for, meaning their costs exceed their billings.
Why is percentage of completion (POC) method important for construction accounting?
The Percentage of Completion (POC) method is crucial because it aligns revenue recognition with the progress of construction projects, as required by GAAP. This method accurately reflects a company's financial performance over the long duration of a project, rather than waiting until project completion.
What are the risks associated with excessive over-billing?
While initial over-billing can improve cash flow, excessive over-billing carries risks such as 'job borrowing,' where funds from one project are used to finance another, potentially leading to liquidity crises. It can also lead to legal issues on federal contracts if progress payments are not commensurate with work performed (Source: FAR 32.503-6).
How do unapproved change orders contribute to under-billing?
Unapproved change orders contribute significantly to under-billing when work is performed before the change order is formally approved and priced. This means costs are incurred without corresponding invoicing, creating a revenue gap. In Washington State, performing work beyond a contract scope without proper notice can even jeopardize payment rights (Source: RCW 60.04.021).
What role does the balance sheet play in reflecting over-billing and under-billing?
On the balance sheet, over-billing (Billings in Excess of Costs) is recognized as a current liability because the contractor has received payment for work not yet performed. Conversely, under-billing (Costs in Excess of Billings) is treated as a current asset, representing earned revenue that has been incurred but not yet invoiced (Source: FASB ASC 606-10-45-1, FASB ASC 606-10-45-2).
How can contractors improve cash flow management in relation to their billing practices?
Contractors can improve cash flow by ensuring timely and accurate billing based on earned revenue, negotiating favorable payment terms, and efficiently managing change orders. Regularly monitoring job costing and project financial health, perhaps with the help of <a href="/learning-center/construction-cash-flow-management-prevention">Scaffold Bookkeeping</a>, can also prevent billing discrepancies.
What are the specific IRS requirements for revenue recognition methods like Percentage of Completion?
The IRS provides guidance for income recognition methods, particularly for long-term contracts. For tax purposes, contractors may be required to use the Percentage of Completion method for certain contracts, especially those that are not considered 'small construction contracts,' which have specific gross receipts tests (Source: IRS Publication 538, Long-Term Contracts).
What is ASC 606 for construction companies?
ASC 606 is an accounting standard that provides a five-step model for construction companies to recognize revenue from contracts with customers. It requires revenue to be recognized over time as the company satisfies performance obligations, typically using an input method like costs incurred to date.
How does ASC 606 change revenue recognition for contractors?
ASC 606 replaced prior industry-specific guidance, moving to a principles-based five-step model. Key changes include a focus on transferring control of goods/services, detailed guidance on variable consideration, and enhanced disclosure requirements, aiming for greater consistency and comparability across the industry.
What are the five steps of ASC 606 revenue recognition?
The five steps are: 1) Identify the contract with a customer; 2) Identify the performance obligations in the contract; 3) Determine the transaction price; 4) Allocate the transaction price to the performance obligations; and 5) Recognize revenue when (or as) the entity satisfies a performance obligation (Source: FASB ASC 606-10-25-1).
Why is 'over time' revenue recognition important in construction?
Most construction projects qualify for 'over time' revenue recognition because the customer simultaneously receives and consumes the benefits as the contractor performs, or the contractor creates an asset controlled by the customer, or the contractor has an enforceable right to payment for work completed. This accurately reflects the ongoing value transfer in long-term projects.
What is variable consideration in construction contracts under ASC 606?
Variable consideration refers to amounts in a contract that can change due to factors like change orders, claims, incentives, or penalties. Under ASC 606, contractors must estimate variable consideration and include it in the transaction price only to the extent that it is probable a significant reversal in revenue recognized will not occur (Source: FASB ASC 606-10-32-11).
How does ASC 606 impact WIP schedules?
Under ASC 606, WIP schedules are still critical but serve to reconcile costs and billings against recognized revenue and costs of earnings. They help identify over- or under-billing positions by comparing revenue recognized under the five-step model to actual project costs and customer billings (Source: GAAP, ASC 606-10-45-1).
Where can a construction company find expert help with ASC 606?
Construction companies can find expert help with ASC 606 implementation and compliance through specialized construction accounting and bookkeeping firms like Scaffold Bookkeeping. These firms offer expertise in setting up robust job costing systems, ensuring accurate financial reporting, and navigating the complexities of the standard.
