What Is Retainage in Construction? A Plain Guide for Contractors

Few things confuse new contractors more than seeing a payment come in short on purpose. You finished the work, you billed for it, and the check is missing five or ten percent. That held-back slice is retainage, and it is a normal part of construction. Understanding how it works, and how to track it, is the difference between expecting that money and being blindsided by a cash crunch. Here is the plain version.

What retainage is

Retainage, sometimes called retention, is a portion of each progress payment that the owner or general contractor holds back until the job is far enough along or fully complete. The idea is to give them leverage: the money is an incentive for the contractor to finish the work and fix any problems before getting paid in full. It is usually 5 to 10 percent, spelled out in the contract, and it applies to each payment along the way.

It flows downhill

On most projects retainage is held at every level. The owner holds it from the general contractor, and the general contractor in turn holds it from the subcontractors. So if you are a sub, money is being kept from you. If you are a general contractor, money is being kept from you by the owner while you are keeping it from your subs. That is why the same job can have retainage moving in two directions at once.

Why it hurts cash flow

Here is the real pain. Retainage is money you have already earned, often money you have already spent to earn, since you paid for the labor and materials. But you do not get it until much later, sometimes months after your part of the work is done. A contractor running on thin margins can be profitable on paper and still struggle to make payroll, because a chunk of every job is sitting in someone else's account waiting on a final sign-off.

When you finally get it back

Retainage is typically released when the work is substantially complete and the punch list, the final fixes and touch-ups, is cleared. On a long project that can be well after you finished your scope. Tracking what is owed, on which jobs, and when it should be released is how you keep that money from quietly going uncollected.

Tracking it on your books

The clean way to handle retainage is to keep it separate rather than burying it in your regular receivables and payables. Money being held back from you is retainage receivable. Money you are holding from your subs is retainage payable. Keeping those in their own accounts, tracked by job, means you always know exactly how much is outstanding and from whom. This is part of solid job costing, where every dollar is tied to the job it belongs to.

One more note: a few states limit how much retention can be held on private projects, and the caps vary, so it is worth checking the rules in the state where you work.

Retainage at tax time

The tax timing of retainage can get technical. Depending on your accounting method and the contract, income may be recognized when it is earned rather than when the cash actually arrives, which can affect what you report and when. The rules here are genuinely nuanced, so retainage is a good thing to raise with your accountant rather than guess at.

How Vuuv helps

Retainage is easy to lose track of precisely because it is money that is not in your account yet. Vuuv's Projects tools tie costs and billing to each job, so the amounts being held back stay visible instead of slipping out of mind, and you can see what each project still owes you before it disappears into a stack of paperwork.
