What is Retainage in Construction?
Retainage is the portion of a contract price (typically 5% to 10%) intentionally withheld from progress payments until a project is substantially complete.
In construction projects, retainage refers to the portion of payments that project owners or general contractors temporarily withhold from contractors or subcontractors. Sometimes referred to as ‘construction retention’ or a ‘holdback,’ this practice is intended to incentivize contractors to meet contractual obligations and complete a project to agreed-upon standards. By retaining a percentage of each payment, owners maintain leverage to address quality issues, incomplete work, or disputes before releasing the full payment.
Retainage is common on many, if not most, construction projects. While the practice of retainage has long been a staple of both public and private construction, statutory regulation was traditionally focused on public works. In recent years, however, more than 30 states have enacted statutes specifically governing retainage on private projects.
Note on Terminology: While the U.S. construction industry typically uses the word retainage, international markets and many modern software platforms use the term construction retention. Both refer to the same financial practice of withholding funds to ensure project completion.
Typically, owners or general contractors will specify the retainage percentage in the contract—historically 10%, though a 5% cap is now the legal maximum in many states, including California and New York, or such other amount as the applicable law requires. According to terms outlined in the contract, withheld funds are only released after specific conditions are met, such as completing inspections, addressing punch lists, or obtaining lien waivers.
Although generally discussed in terms of owners and general contractors, the practice of retainage on a construction project may also impact subcontractors and suppliers of materials.

Retainage Laws
Retainage practices are subject to federal and/or state laws, which are designed to achieve fairness and prevent abuse.
Federal Retainage Laws
Direct federal construction contracts—those where a federal agency, such as the Department of Defense, is the project owner—are governed by the Federal Acquisition Regulation (FAR). The FAR serves as the primary set of regulations pertaining to the acquisition of goods and services by federal agencies, including construction projects and their payment practices. It applies to acquisitions beyond the construction field, though, so contractors should focus on the provisions that specifically apply to construction.
Several aspects of retainage are explicitly addressed within the FAR, including:
- Retainage Percentage – The Government may withhold up to 10% of progress payments if the Contracting Officer determines that satisfactory progress has not been achieved. For work deemed substantially complete, or distinct project phases that are finalized, payments may be made without additional retainage.
- Progress Payments – Progress payments are made on the basis of work completed and are usually paid monthly or more frequently. Contractors are required to provide detailed support for payments, including itemized progress information, subcontractor payment statuses, and other data.
- Conditions for Retainage Release – Retainage can be released earlier than project completion if the Contracting Officer determines that satisfactory progress has been made. Furthermore, once the work is substantially complete, the Contracting Officer is generally required to release all remaining withheld funds to the contractor, keeping only an amount deemed necessary to protect the government’s interest until final acceptance.
- Certified Requests – Contractors must submit certified payment requests. This certification must explicitly state that all payments due to subcontractors and suppliers from previous progress payments have been made and that timely payments will be made from the proceeds of the current payment request.
State Retainage Laws
State retainage laws govern projects within their jurisdictions and typically distinguish between state-funded public projects and privately funded projects. Public projects often have stricter regulations to ensure accountability for taxpayer funds.
The retainage laws that apply to state-funded projects may differ from those that apply to other public entities, such as counties, municipalities, and boards of education. Retainage rates may also vary across different types of state-funded projects, with differing rates for highway construction projects than for other types of construction, for example.
Private projects generally allow more flexibility, but the parties to those projects must still comply with any applicable state laws.
- Retainage Caps – For state-funded projects, retainage is often capped to protect contractor cash flow while maintaining owner security. States that include retainage limits in their statutes are roughly divided between those that cap retainage at 5% and those that cap it at 10%, with a slightly larger number of states imposing a 5% cap. New Mexico prohibits retainage for most publicly and privately funded projects, while California caps retainage on private projects at 5% as of 2026. On private projects in other states, retainage caps are generally negotiable unless otherwise specified by state law. Some states that do not specify retainage caps for private projects do have laws regarding other aspects of retainage.
- Timelines for Retainage Release – Many state laws identify specific deadlines for releasing retainage on state-funded projects. The states that do so tend to tie the release to things such as acceptance, completion, and final payment. California mandates release within 60 days of completion for public works and 45 days of completion for private projects, while Florida requires public entities to release retainage within 20 business days of the creation of the project’s punch list. Private projects may be governed by state law and, if they are not, the parties are bound by the terms of the contract.
- Escrow Requirements – Some states, including Connecticut, Louisiana, Michigan, Ohio, and Tennessee, require retainage for certain state-funded public projects to be held in interest-bearing escrow accounts, providing additional security for contractors. This requirement does not typically extend to private projects, although some states, such as Tennessee and Louisiana, do mandate interest-bearing escrow accounts for private construction retainage.
- Prompt Payment Acts – The federal government and most states (with the exception of New Hampshire) have Prompt Payment Laws. These laws address the required timing of payments as well as penalties for late retainage payments. They often include provisions requiring general contractors to promptly release retainage to subcontractors after receiving it from the project owner. More than half the states require prompt payment on private projects as well.
While public projects tend to be more tightly regulated than private projects, contractors must carefully review state retainage laws and contract terms for all projects to ensure compliance, especially when operating across multiple jurisdictions.
Relationship Between State & Federal Retainage Laws
The relationship between federal and state retainage laws depends on the contract type and the source of project funding. For direct federal procurement contracts, the Federal Acquisition Regulation (FAR) takes precedence and controls caps, progress payment schedules, and conditions for release. While the FAR includes specific subcontractor protections under the Prompt Payment Act—such as mandatory payment timelines and notice requirements—it does not set a statutory cap on retainage between prime contractors and subcontractors. Consequently, state laws may still apply to these subcontracts to limit withholding percentages.
State laws govern retainage for state-funded public projects, privately funded projects, and many federally assisted projects managed by state agencies. These laws may include requirements for caps, timelines, and escrow accounts. Contractors working on projects funded jointly by federal and state sources must navigate these overlapping provisions.
When operating across multiple jurisdictions or on complex projects, contractors should work closely with project owners and legal advisors to confirm which laws apply and how to address potential conflicts. While the project’s contract typically outlines the specific terms, these provisions must comply with applicable state or federal statutes. In many jurisdictions, such as New York and California, mandatory 5% retainage caps are non-waivable and automatically override any conflicting or excessive retainage terms found in the contract.
Retainage in Construction Contracts
Retainage terms in construction contracts define how funds are withheld and released, ensuring they adhere to statutory requirements. These terms must align with current compliance standards, and typically address several key components:
Holding Retainage
Typically, an owner will withhold retainage from the general contractor, who is likely to withhold retainage from subcontractors. The contract or applicable state laws generally specify where retainage is to be held and whether interest will accrue. In some jurisdictions, for example, retainage must be placed in an interest-bearing escrow account by law, while in others, interest may only apply as a statutory penalty if the funds are not released within the required timeframe.
Retainage Percentages
Contracts specify the portion of each payment withheld as retainage, which is increasingly capped at 5% depending on the jurisdiction. Public projects follow federal or state mandates, while private contracts allow for negotiated terms in states without statutory caps.
Conditions for Retainage & Retention Release
Retainage is released after contractors meet defined milestones and closeout requirements, including:
- Substantial completion – when the project is sufficiently complete to be used for its intended purpose.
- Completion of punch list items – the resolution of all minor defects or incomplete work identified during the final walkthrough.
- Final acceptance – when the owner or architect confirms the project has passed final inspections and complies with all project specifications.
- Payment resolution – when lien waivers have been submitted and it is verified that all payments for labor and materials have been addressed.
- Confirmation of subcontractor payments – as required in specific contracts or under state prompt payment laws.
Common Retainage Contract Terms
Beyond these essentials, contracts often include provisions to address cash flow and flexibility:
- Tiered Retainage Reductions – Retainage percentages may decrease as the project nears completion.
- Partial Retainage Release for Subcontractors – Subcontractors may receive retained funds after completing their portion of the work, even if the larger project continues.
- Retainage Alternatives – Although retainage is common in construction contracts and often mandated for public works, there are alternatives that may be permissible in certain jurisdictions or by private agreement.
Retainage terms vary depending on the project type and jurisdiction, and contractors should review them closely to understand their obligations and payment schedules.
Potential Alternatives to Retainage
In some cases, contractors may be able to substitute one of the following alternatives to retainage:
- Retainage bond – A retainage bond specifically allows a contractor to receive full progress payments by providing a bond in place of cash withholding.
- Alternate security – A bank letter of credit, commonly a standby letter of credit, may be more cost-effective than a bond, while guaranteeing available funds in the event of a failure by the contractor. United States Treasury bonds or other similarly low-risk investments may also be used in place of retainage if a project owner agrees.
- Escrow account for retainage – Unlike the alternatives mentioned above, this option is very similar to standard retainage withholding, except that the funds are placed into an escrow account managed by a third party. An escrow account allows the contractor to earn interest on the money being held, which is typically released to them along with the principal upon project completion.
- Negotiated approach – Although not a real retainage replacement, the party from whom retainage will be withheld may be able to negotiate to achieve a lower overall percentage, or a decreasing retainage amount as project milestones are achieved.
Retainage Impacts
Retainage clearly impacts multiple parties on any construction project. Those impacts are not uniform. Some parties are generally thought to benefit from retainage, while it may be a detriment to others.
- Owner – Widely recognized as the party that receives the most benefit from retainage, owners can use it to manage project risks and quality control.
- Contractor – In an industry known for its tight profit margins, retainage can negatively impact the cash flow of contractors, and others down the chain, because they will be required to pay all of the expenses they incur as a result of the project (wages, supplies, equipment), while being required to wait—sometimes for long periods—for payment in full.
- Subcontractor – Subcontractors often feel the most significant impact from retainage, particularly those who complete their portion of work in the early stages of a project. However, many modern contracts and state prompt payment laws now provide for ‘line-item’ release, which allows subcontractors to receive their retainage shortly after their specific work is accepted rather than waiting for the entire project to conclude.
- Supplier of materials – While some material suppliers may have retainage withheld, many operate under standard commercial terms that require full payment shortly after delivery, and in some jurisdictions, material-only suppliers are exempt from retainage by law. For those who are subject to it, however, the impact is significant; they may incur all production and delivery costs at the start of a project but be forced to wait until the final stages of the job to receive their remaining balance.
Sample Retainage Clause
Here is a sample retainage clause that might appear in a construction contract. Keep in mind that as of 2026, retainage laws have changed significantly in several jurisdictions so it is critical to tailor the language to comply with current local regulations and mandatory escrow requirements. This sample retention release language can be modified to fit your specific project needs and local jurisdiction.

Retainage Example
To better understand how retainage works in practice, consider a $5 million commercial construction project. A general contractor (GC) is hired to oversee the construction of an office building. The project owner and GC agree to a 5% retainage clause in their contract—reflecting statutory caps now common in major markets—meaning 5% of every progress payment will be withheld until specific conditions are met.
The GC submits monthly invoices to the project owner for work completed. In the first month, the GC invoices the owner for $500,000 worth of completed work. With retainage applied, the owner withholds $25,000 and pays the GC $475,000. This process repeats each month as progress payments are made, and by the end of the project, the owner has withheld a total of $250,000 in retainage. These funds provide the owner with financial security, incentivizing all contractual obligations to be met before the full payment is released.
The GC, in turn, applies a similar 5% retainage to its payments to subcontractors to comply with flow-down requirements. When a plumbing subcontractor invoices the GC for $100,000 in the first month of the job, the GC withholds $5,000 and pays the subcontractor $95,000, creating a cascading effect. This encourages subcontractors to fulfill their commitments, but it also delays cash flow across the construction hierarchy.
Once the project reaches final completion—after the owner conducts inspections and verifies that the GC has resolved all punch list items, submitted lien waivers, and met all other contract conditions—the owner releases the full $250,000 retainage to the GC. The GC then disburses the subcontractors’ retainage, typically within a strict timeframe required by prompt payment laws.
For larger projects or phased completions, retainage may be released in stages. The plumbing subcontractor’s retainage could be released upon the completion and inspection of their portion of the work, even if the rest of the building is still under construction. This flexibility helps mitigate cash flow pressures while maintaining accountability.
Although retainage provides necessary financial protection for project owners, it can strain cash flow for contractors and subcontractors. These parties must carefully manage their finances to handle delayed payments and plan in advance for retainage release timelines.
Accounting for Retainage
Retainage is tracked as either a liability or an asset, depending on whether it is withheld from subcontractors or retained by the project owner. In construction accounting, these balances are treated differently based on who withholds the funds.
- Retainage Payable – These are funds withheld by a contractor from payments to subcontractors. They are recorded as a liability in the contractor’s ledger until the funds are released.
- Retainage Receivable – These are funds withheld from the contractor by the project owner. They are recorded as an asset on the contractor’s balance sheet; however, under ASC 606, the associated revenue is typically recognized as performance obligations are satisfied, rather than when the funds are actually paid out.
Because revenue is generally recognized as work progresses rather than when the retainage is released, managing these balances effectively is critical for maintaining an accurate picture of a company’s financial health. This can be challenging—especially when dealing with large projects, multiple projects, or projects spanning multiple jurisdictions with varying retainage laws.
Retention accounting requires precision in tracking and reporting these balances. Most contractors rely on specialized software to track retention release timelines and ensure liquidity is managed properly. Accounting tools like CMIC and NetSuite automate retainage payable and retainage receivable management, reducing administrative overhead.
Software for Retainage Accounting
Modern construction accounting platforms simplify retainage management by offering specialized features that automate processes, verify compliance, and improve accuracy. Some of the key capabilities of these tools include:
- Retainage Tracking – Many platforms offer tools to monitor retainage balances across projects, helping contractors maintain awareness of withheld amounts. These tools often include dashboards that provide real-time updates on payment statuses, outstanding balances, and upcoming deadlines.
- Automated Retainage Calculations – The calculation of retainage amounts, whether based on fixed percentages, tiered reductions, or specific milestones, is handled seamlessly by accounting software. This ensures consistency with contract terms and reduces human error.
- Retainage Billing and Invoicing Tools – Retainage software simplifies invoicing by generating retainage-specific invoices or incorporating withheld amounts into standard forms like AIA G702 and G703. These tools also track submission statuses and payment requests, integrating seamlessly with broader accounting workflows to ensure efficiency and compliance.
- Compliance Monitoring – Tools designed to support compliance help contractors track escrow requirements, calculate interest on retained funds, and generate reports for audits or legal needs. These features ensure alignment with relevant laws.
- Escrow Account Management – Where retainage laws require escrow accounts, software solutions track the deposited amounts and accrued interest. Contractors can use this functionality to streamline documentation and meet obligations for retainage release.
- Multi-Project Functionality – For contractors managing numerous projects, retainage features allow adjustments for varying state laws and contract-specific retainage terms. This functionality simplifies oversight across diverse jurisdictions and project types.
- Integration with Job Costing – Many retainage tools integrate with job costing systems, enabling contractors to track withheld amounts alongside project work. This provides a clearer view of how retainage impacts cash flow and liquidity without distorting the total project budget or the associated cost codes used to record work performed.
Retainage plays a critical role in balancing financial security and contractual obligations in construction projects. Accurate tracking, streamlined processes, and adherence to legal requirements ensure that withheld funds are handled efficiently and fairly. By combining disciplined accounting practices with modern software solutions, contractors can navigate the complexities of retainage while maintaining financial stability and fostering trust with project stakeholders.
