Subcontractor flow-down clauses and certified payroll

What a flow-down clause actually is

A flow-down clause is a paragraph, or an attached exhibit, that pulls terms from the contract above you into the contract you signed, so the rules binding the prime also bind every tier underneath it. On most private jobs it is whatever the GC's attorney chose to write.

On a California public works job it is not a choice. If a subcontractor's worker is not paid the prevailing rate, the general contractor is not liable for the resulting penalty unless it had actual knowledge, "or unless the prime contractor fails to comply with all of the following requirements," the first being that "the contract executed between the contractor and the subcontractor for the performance of work on the public works project shall include a copy of the provisions of this section and Sections 1771, 1776, 1777.5, 1813, and 1815" (Labor Code 1775(b)(1)). That is the flow-down clause. Done right, it is already in your subcontract, usually as an exhibit reprinting the six sections in full.

The six sections that have to be in your subcontract

Registration is not one of the six sections named in 1775(b)(1). It flows down through a different mechanism, covered below.

What the clause means for you day to day

Section 1775(b) puts three more duties on your general contractor, and all three show up in how the GC treats you during the job:

• Periodic review of your certified payroll. The GC must "monitor the payment of the specified general prevailing rate of per diem wages by the subcontractor" through "periodic review of the certified payroll records" (1775(b)(2)). This is why a GC asks for your certified payroll even when a portal like LCPtracker or PRISM already collects it for the awarding body; see GC rejected your certified payroll.
• Corrective action if a problem surfaces. Once aware of an underpayment, the GC must "diligently take corrective action to halt or rectify the failure, including, but not limited to, retaining sufficient funds due the subcontractor" (1775(b)(3)), the statutory basis for a GC holding back your progress payment over a wage question.
• An affidavit before final payment. The GC must "obtain an affidavit signed under penalty of perjury from the subcontractor" confirming payment of the prevailing rate and any amounts under section 1813 (1775(b)(4)). Read that affidavit before signing it.

The safe harbor protects your GC, not you

All of the above exists for the general contractor's benefit, not yours. Complying with paragraphs (1) through (4) is what lets the GC avoid liability for a penalty triggered by your underpayment. That protection runs one direction: it does not reduce, waive, or transfer the penalty itself. If you paid a worker below the determination, the $40 to $200 per worker per calendar day exposure under Labor Code 1775(a) is still yours. From January 1, 2027, SB 909 raises that range to $56 to $280 (see what SB 909 changes). The clause explains why your GC reviews your payroll and holds your money when something looks wrong. It is not evidence the GC is taking the underlying risk off your hands.

One penalty that does not travel the other way: your own recordkeeping

Here is the mirror image, and it cuts in your favor. The recordkeeping duty behind the $100 per worker per calendar day forfeit for missing a written records request works differently from the wage penalty above. From January 1, 2027, SB 909 raises the records request forfeit to $140. The statute says directly that "a contractor is not subject to a penalty assessment pursuant to this section due to the failure of a subcontractor to comply with this section" (Labor Code 1776(h)). If your own records are late or incomplete, that forfeit runs to you, not up the chain to your GC. See Labor Code 1776, subdivision by subdivision.

Registration flows down too, and the penalty for it cannot be pushed onto you

Registration works through a separate section, and it runs in both directions. Labor Code 1771.1(a) says a "contractor or subcontractor shall not be qualified to bid on, be listed in a bid proposal... or engage in the performance of any contract for public work" unless currently registered under DIR's registration program. That applies to you directly, whether or not your contract mentions it.

Where it gets interesting: under 1771.1(h)(1), a higher tiered contractor that subcontracts with an unregistered lower tier subcontractor owes its own civil penalty, $100 per day the unregistered sub worked, capped at $10,000. But 1771.1(h)(4) draws a hard line around who pays it: "a subcontractor shall not be liable for any penalties assessed against a higher tiered public works contractor or subcontractor pursuant to paragraph (1)," and "a higher tiered public works contractor or subcontractor may not require a lower tiered subcontractor to indemnify or otherwise be liable for any penalties." A subcontract asking you to cover that penalty is asking for something the statute forbids.

Filing with DIR is still yours, clause or not

None of the flow-down machinery above changes who files what with the state. DIR's own FAQ on certified payroll reporting states that all contractors and subcontractors on covered public works projects must submit electronic certified payroll records directly to the Labor Commissioner (DIR, certified payroll reporting FAQ). Your GC reviewing your payroll under 1775(b)(2), or a portal collecting it for the awarding body, satisfies neither channel for the other. Both run at once, and both are your responsibility.

What to check before you sign

• The six sections, attached or referenced. Their absence does not remove your obligations; it only affects your GC's liability shield.
• A weekly certified payroll submission requirement to the GC. Separate from your direct DIR eCPR filing.
• A retention or withholding clause. Know what triggers it before a payment gets held.
• The final payment affidavit. Confirm what it asks you to swear to, under penalty of perjury.
• Indemnification language tied to registration. Language making you indemnify your GC's own 1771.1(h)(1) penalty asks for something the statute already bars.

Where WellStanding fits

The flow-down clause tells your GC what to ask you for. It does not change what you have to produce: the accurate payroll records Labor Code 1776(a) requires you to keep, a validated DIR eCPR filing, and DAS 140 and DAS 142 paperwork when apprentices are on the job. WellStanding builds those filings from the payroll export you already run in QuickBooks, ADP, Paychex, Gusto, or Sage, with a person reviewing every filing, so the copy your GC asks for under 1775(b)(2) and the record DIR requires are the same clean filing. The first one is free. Pricing is on the home page.
