Retainage vs. holdback: the difference

Retainage and holdback are the same idea wearing two different rulebooks. Both hold back a slice of every progress payment until the work is finished and proven. The difference is where the rule comes from: in the United States retainage is mostly a matter of contract and state statute, while in Canada holdback is a statutory amount that lien legislation forces the payer to withhold whether anyone likes it or not. If you have ever moved a crew across the border, or bought software that only speaks one of these dialects, that difference has probably cost you a headache. Here is what actually separates the two.

We deal with both at Quality Gypsum Services, our commercial drywall business in Calgary, Alberta, which is why SubTrade ships a calculator for each. This is the plain-language version.

The one-line answer

Retainage is the US term for money withheld from a contractor's progress payments, usually 5% to 10%, governed mainly by the contract and by state retainage law, and released when the work is accepted. Holdback is the Canadian term for the same withholding, but it is a statutory amount, most commonly 10%, that lien legislation requires the payer to retain as a fund unpaid subcontractors can claim against, and it is released after a lien period tied to substantial performance. Same purpose, different legal machinery.

Retainage in the United States

In the US, retainage lives primarily in your contract. The percentage, the schedule, and whether it steps down partway through the job are negotiated terms, layered on top of whatever the state allows.

The common structure is 5% to 10% withheld from each progress payment. Many private contracts and public jobs allow the rate to drop, say from 10% to 5%, once the project passes the halfway mark and the owner is comfortable. State law sets the outer limits: several states cap retainage on public work, some require it to be held in a separate interest-bearing account, and prompt-pay statutes govern how fast it has to be released after acceptance. Because it varies so much, the rate on the job in one state tells you nothing about the job in the next.

US retainage also rides on AIA-style billing, the G702 and G703 pay application, where the retainage line is calculated right on the face of the draw. Because the numbers differ state by state, run your own with our construction retainage calculator, which covers all fifty states plus DC.

Holdback in Canada

Canadian holdback is not negotiable in the same way, and that is the whole point. It is set by each province's lien or builders' lien legislation, so the percentage does not change from contract to contract within a province. The payer is legally required to hold it back and generally cannot waive it by contract.

The standard is 10% of the value of work done across most of the country, with Manitoba the notable exception at 7.5%. The held amount is not just security for the owner: it is a fund that unpaid subs and suppliers can lien against if someone up the chain fails to pay. Release is tied to substantial performance and a statutory lien period rather than to a contract milestone, and on large, long projects some provinces now require holdback to be released annually rather than at the very end. For the full breakdown of rates and release periods, see our guide to construction holdback by province, and run your own draw through the construction holdback calculator.

Side by side

The row that trips up cross-border subs most is the second one. A US contract can talk you down to 5% retainage; a Canadian holdback percentage is fixed by the province, so there is nothing to negotiate. Reading a Canadian holdback like a negotiable retainage term is how subs end up mis-forecasting cash on their first job north of the line.

Why the difference matters for your cash flow

Whichever name it wears, this is your money financing someone else's risk. On a $500,000 contract, a 10% withholding is $50,000 you have earned but cannot touch until release. What changes across the border is the release logic, and that changes when the cash comes back.

Under US retainage, the release often hangs on acceptance and can step down mid-project, so you may recover half of it before the job even closes. Under Canadian holdback, release is anchored to substantial performance and the lien clock, so it tends to arrive in one lump after the period expires. Same dollars, very different timing, and if your forecast assumes the wrong pattern you plan your working capital wrong.

The other trap is tax. In Canada, GST or HST on the holdback is generally not payable when you invoice; it follows when the holdback is actually released or the period expires. That timing has no clean US equivalent, so cross-border subs who treat the two identically get their remittances out of step. For how that plays out on an actual draw, see progress billing and holdback in Canada.

How to track each without losing a dollar

The practical problem is not understanding the difference, it is keeping two different release clocks straight across a stack of active jobs. A retainage step-down you forgot to bill, or a holdback whose lien period quietly expired three weeks ago, is money sitting in someone else's account because nobody was watching the date.

What works is tracking the withheld amount per job with its own release rule attached: the retainage percentage and step-down for US jobs, the statutory percentage and lien period for Canadian ones, both fed off your actual progress rather than a spreadsheet somebody updates on draw day. That way the release date is on the calendar before you need it, and the number you claim is backed by the work in place. You can see how we fold that into our progress billing tools, with the rest of the system in our construction management features.

FAQ

Is holdback the same as retainage?

They are the same concept, money withheld from progress payments until work is proven, but they follow different rules. Retainage is the US term, governed mainly by contract and state law. Holdback is the Canadian term, a statutory amount fixed by provincial lien legislation.

What is the difference between retainage and holdback?

Retainage is usually negotiable within state limits and released on acceptance, often stepping down partway through a job. Holdback is a fixed statutory percentage, most commonly 10%, that the payer must retain and release after substantial performance and a lien period. One is largely contractual, the other is set by law.

How much is retainage vs holdback?

US retainage is typically 5% to 10% and can step down mid-project. Canadian holdback is 10% across most provinces, with Manitoba at 7.5%. The US figure is a contract term within state limits; the Canadian figure is statutory.

Which one applies to my project?

The location of the work decides it. A project in the United States uses retainage under that state's rules. A project in Canada uses statutory holdback under that province's lien legislation. Cross-border subs deal with both and should track each on its own release clock.

Do Canadian holdback and US retainage get released the same way?

No. US retainage often releases on acceptance and can come back partway through the job. Canadian holdback is anchored to substantial performance and a lien period, so it usually arrives in one payment after that period expires.
