Completed Contract Method

Overview: The Completed Contract Method for 2026 Tax Planning

The Completed Contract Method (CCM) is a specialized accounting method primarily utilized within the construction industry. It allows businesses to defer the recognition of income and expenses associated with long-term contracts until the project is substantially complete. This deferral can significantly impact a company's cash flow and tax liability, making it a crucial consideration for eligible contractors and developers. Recent legislative changes, particularly the One Big Beautiful Bill Act (OBBBA) passed in July 2025, have expanded the applicability of CCM, especially for residential construction contracts, making it even more relevant for the 2026 tax year and beyond [1] [2].

What is the Completed Contract Method?

The Completed Contract Method (CCM) is an accounting approach where all revenues and related expenses from a long-term contract are recognized only when the contract is fully completed. Unlike the Percentage of Completion Method (PCM), which recognizes income and expenses as work progresses, CCM defers all financial recognition until the project reaches substantial completion. This method is particularly beneficial for projects with uncertain timelines or costs, as it aligns income recognition with the finalization of the project, potentially improving cash flow by delaying tax payments [3] [4].

Historically, the use of CCM was restricted to specific types of contracts, primarily home construction contracts involving four or fewer units, or by small contractors meeting certain gross receipts thresholds. However, the OBBBA has significantly broadened its scope, allowing more residential construction projects to qualify. This expansion is a game-changer for many in the construction sector, offering new opportunities for tax planning and financial management [1] [2].

Who Qualifies for the Completed Contract Method?

Eligibility for the Completed Contract Method has been expanded for the 2026 tax year due to the OBBBA. Generally, the following criteria determine who qualifies:

• Construction Contracts: The method is primarily for long-term construction contracts.
• Residential Construction Contracts: Under the OBBBA, eligibility for residential construction contracts has been significantly expanded. A contract qualifies as a residential construction contract if at least 80% of the estimated total costs (at the time the contract is entered into) are attributable to the construction or improvement of real property that is expected to be used as dwelling units. This includes apartments, condominiums, senior living facilities, student housing, and even mixed-use developments where the residential component meets the 80% threshold [2].
• Small Contractors: Even before OBBBA, small contractors could use CCM for certain contracts. A small contractor is generally defined as one whose average annual gross receipts for the three taxable years preceding the current tax year do not exceed a specific threshold (for 2026, this threshold is subject to inflation adjustments, but was $25 million for tax years beginning after 2017) [4]. For these contractors, CCM can be used for any construction contract that is expected to be completed within two years.
• Home Construction Contracts: Contracts for the construction of dwelling units (e.g., houses, townhouses) that are not part of a larger residential project (i.e., four or fewer units) have historically qualified for CCM [1] [4].

It is crucial for taxpayers to carefully assess their contracts against these criteria, especially the 80% cost attribution rule for residential construction, to ensure eligibility [2].

How to Claim the Completed Contract Method

Claiming the Completed Contract Method involves specific accounting and reporting procedures. Taxpayers must adopt CCM as their accounting method for eligible long-term contracts. This typically requires:

• Method Adoption: For new businesses or those entering into qualifying contracts for the first time, CCM can be adopted as an initial accounting method.
• Change in Accounting Method: If a business previously used a different method (like PCM) and now qualifies for and wishes to use CCM due to the OBBBA expansion or other reasons, they generally need to file Form 3115, Application for Change in Accounting Method, with the IRS. This form is used to request permission to change an accounting method and may involve adjustments under Section 481(a) [5].
• Record Keeping: Meticulous record-keeping is essential. Businesses must clearly identify and track residential construction contracts in their work-in-progress (WIP) schedules, separating them from non-qualifying projects. Consistent and well-documented methodologies are required to confirm that at least 80% of the original estimated project costs qualify as residential construction [2].
• Tax Reporting: Income and expenses from contracts accounted for under CCM are reported on the business's tax return (e.g., Form 1120 for corporations, Form 1065 for partnerships) in the tax year the contract is completed. Schedule UTP (Uncertain Tax Position Statement) might be relevant for certain large corporations.

Consulting with a tax professional is highly recommended to navigate the complexities of adopting or changing to the CCM and ensuring proper compliance.

2026 Limits, Amounts, or Rates

For the 2026 tax year, the primary consideration for the Completed Contract Method (CCM) revolves around the expanded eligibility criteria rather than specific monetary limits or rates directly tied to the deduction itself. The key changes are primarily qualitative, focusing on which contracts now qualify for CCM under the One Big Beautiful Bill Act (OBBBA) [1] [2].

While there isn't a direct 'limit' on the amount of deduction, the ability to defer income recognition effectively defers tax payments. The most significant 'amount' related to 2026 is the expanded scope for residential construction contracts: those where at least 80% of the estimated total costs are attributable to residential property [2]. For small contractors, the gross receipts threshold for using CCM for contracts expected to be completed within two years remains a critical factor. This threshold, which was $25 million for tax years beginning after 2017, is subject to inflation adjustments for 2026. Taxpayers should consult the latest IRS guidance for the precise inflation-adjusted figure [4].

Common Mistakes That Cost Taxpayers Money

While the CCM offers significant tax advantages, several common mistakes can lead to costly errors and potential IRS scrutiny:

• Misinterpreting Eligibility: Incorrectly assuming a contract qualifies for CCM, especially regarding the 80% residential cost threshold or the definition of a 'small contractor.' This can lead to improper deferral of income and subsequent penalties [2] [4].
• Inadequate Record-Keeping: Failing to maintain detailed records that substantiate the classification of contracts as residential construction or small contracts. Poor documentation makes it difficult to defend the use of CCM during an audit [2].
• Improper Change in Accounting Method: Not filing Form 3115 when transitioning from PCM or another method to CCM. Any change in accounting method requires IRS approval [5].
• Inconsistent Application: Applying CCM inconsistently across similar projects or failing to apply it uniformly within a single project. Consistency is key to IRS compliance.
• Ignoring Look-Back Rules (where applicable): While the OBBBA has provided relief from look-back rules for certain residential construction contracts, it's crucial to understand when these rules still apply to other long-term contracts. The look-back method generally requires taxpayers to pay or receive interest on the difference between the tax computed using estimated contract price and costs, and the tax computed using actual contract price and costs [6].
• Failure to Monitor Gross Receipts: For small contractors, exceeding the gross receipts threshold can disqualify them from using CCM, necessitating a change in accounting method [4].

IRS Code Section Reference

The primary Internal Revenue Code (IRC) section governing long-term contracts and the Completed Contract Method is IRC Section 460 - Long-Term Contracts. Specifically:

• IRC Section 460(a): Generally requires taxpayers to use the Percentage of Completion Method (PCM) for long-term contracts.
• IRC Section 460(e): Provides exceptions to the general rule, allowing the use of the Completed Contract Method for certain contracts, including home construction contracts and certain small construction contracts [4].

Treasury Regulations, particularly Treas. Reg. §1.460-3(b), provide further guidance on these exceptions and the application of the CCM [4].
