Question 1

What is the difference between a subcontractor and an employee?

Accepted Answer

A subcontractor is an independent business that performs work for another contractor under a contract — they control their own methods, supply their own tools, set their own schedule, carry their own insurance, and pay their own self-employment taxes. An employee, by contrast, works under the direction and control of an employer who withholds payroll taxes, provides workers' compensation coverage, and typically supplies the tools and workspace. The IRS uses a multi-factor common-law control test, the Department of Labor uses an economic reality test, and many states (notably California under AB 5) apply a stricter ABC test. Misclassifying an employee as a subcontractor can result in back taxes, unpaid overtime, penalties, and class-action exposure.

Question 2

How does the IRS test whether someone is properly classified as an independent subcontractor?

Accepted Answer

The IRS evaluates classification using three categories: behavioral control (does the hiring party control how the work is performed), financial control (does the worker have a meaningful investment, opportunity for profit and loss, and the ability to work for other clients), and the type of relationship (written contracts, employee-style benefits, permanency, and whether the work is a key aspect of the business). No single factor is decisive. A solid subcontractor agreement that documents independence, requires the sub to carry insurance and use its own tools, allows the sub to take other jobs, and ties payment to deliverables rather than hours strengthens the classification. File Form SS-8 if you need an official IRS determination, but most contractors prefer to draft carefully and avoid scrutiny.

Question 3

What is a lien waiver and when should I require one from my subcontractor?

Accepted Answer

A lien waiver is a signed document in which a subcontractor (or their suppliers) gives up the right to file a mechanic's lien against the project property in exchange for payment. There are four common variants: conditional and unconditional, partial and final. Best practice is to require a conditional progress lien waiver before issuing each progress payment, and a final unconditional lien waiver before releasing retainage at project completion. Several states — including California, Texas, and Florida — have statutory lien waiver forms that must be used to be enforceable. Skipping lien waivers exposes the prime contractor and the owner to double-payment claims if the sub fails to pay its own workers or suppliers.

Question 4

How should indemnification be structured in a subcontract?

Accepted Answer

Indemnification provisions allocate the risk of third-party claims arising out of the subcontractor's work. A typical clause requires the sub to defend, indemnify, and hold harmless the prime contractor (and the owner as additional indemnitee) from claims arising out of the sub's negligence, willful misconduct, or breach of contract. Many states have anti-indemnity statutes that limit or prohibit a sub's obligation to indemnify the prime for the prime's own negligence — California Civil Code § 2782 voids such 'Type I' indemnities in most construction contracts. Use a 'comparative fault' or 'to the extent caused by' indemnity to stay within the law in those states, and always pair indemnification with an additional insured endorsement on the sub's CGL policy.

Question 5

What insurance should I require from my subcontractors?

Accepted Answer

At a minimum, require commercial general liability (CGL) insurance with limits of at least $1 million per occurrence and $2 million aggregate, automobile liability of $1 million combined single limit, statutory workers' compensation for all employees, and employer's liability of $500,000 or more. For higher-risk trades or larger projects, layer on a $5 million excess/umbrella policy and require professional liability for design-build subs. Always require the sub to name the prime contractor and the owner as additional insureds on a primary, non-contributory basis (ISO endorsements CG 20 10 and CG 20 37 are the standards), waive subrogation against you, and provide certificates and endorsements before mobilization. Re-verify coverage annually and at renewal.

Question 6

What payment terms are typical in a subcontractor agreement?

Accepted Answer

Most construction subcontracts use monthly progress billing tied to a schedule of values, with payment due 10 to 30 days after the prime contractor receives payment from the owner — a 'pay-when-paid' clause. Some subcontracts use 'pay-if-paid' language that makes owner payment a condition precedent to the sub being paid; courts in California, New York, and several other states refuse to enforce pay-if-paid clauses as written, treating them as pay-when-paid timing provisions. Retainage of 5% to 10% is commonly held until substantial completion. Federal prime contracts under the Prompt Payment Act require flowdown of strict payment timing to subs (7 days from prime payment), and many states have similar prompt-payment statutes for public projects.

Question 7

What are the biggest risks for prime contractors when using subcontractors?

Accepted Answer

The largest exposures are joint employer liability (under the Fair Labor Standards Act and the NLRA, a prime can be held responsible for a sub's wage and hour violations), worker classification claims (back taxes and benefits if a sub's workers are reclassified as the prime's employees), mechanic's lien claims by unpaid sub-tier subs and suppliers, OSHA multi-employer worksite citations, and quality and warranty exposure if the sub's work fails after the project closes. Mitigation tools include a tightly drafted subcontract with strong indemnity and insurance provisions, vendor pre-qualification, lien waiver tracking, regular safety audits, and adequate retainage. Many large primes now require subs to enroll in subcontractor default insurance (SDI / SubGuard) instead of payment and performance bonds.

Question 8

Can a subcontractor hire its own subcontractors (sub-subs)?

Accepted Answer

Generally yes, but the prime subcontract should require the sub to obtain the prime contractor's prior written approval before hiring lower-tier subs and to flow down all material terms — including insurance, indemnity, lien waiver, safety, and payment provisions — to those sub-subs. The prime should also retain audit rights and the right to communicate directly with sub-tier subs in the event of a payment dispute. Federal subcontracts under the FAR mandate flowdown of specific clauses (FAR 52.244-6 and others) to lower-tier subs. Without proper flowdown, a prime contractor can be exposed to lien claims, bond claims, and direct liability from workers it never hired.

Question 9

What is a pay-if-paid clause and is it enforceable?

Accepted Answer

A pay-if-paid clause states that the prime contractor's receipt of payment from the owner is a condition precedent to the prime's obligation to pay the subcontractor — meaning if the owner never pays, the sub never gets paid. This shifts the credit risk of the owner from the prime to the sub. Several states have refused to enforce pay-if-paid clauses on public-policy grounds or have construed ambiguous language as a mere pay-when-paid timing clause: California (Wm. R. Clarke Corp. v. Safeco), New York (West-Fair Electric Contractors v. Aetna), and North Carolina by statute. Other states enforce them strictly if the language is clear and unambiguous. If you intend to use a pay-if-paid clause, draft it explicitly using words like 'condition precedent,' but understand its enforceability varies by state.

Question 10

Does the subcontractor need a contractor's license?

Accepted Answer

Yes, in most states. A subcontractor performing licensed trade work — electrical, plumbing, HVAC, general construction above a dollar threshold — must hold the appropriate state contractor's license, and many states (including California, Nevada, Arizona, and Florida) bar an unlicensed contractor from suing to collect on the contract or even forcing return of money already paid. Verify license status through the state contractor licensing board before contract execution and keep a copy of the certificate in the project file. Federal projects under the Davis-Bacon Act and Service Contract Act may also require certified payroll, EEO compliance, and registration in SAM.gov.

Question 11

What happens if the subcontractor abandons the job?

Accepted Answer

A well-drafted subcontract addresses abandonment as an event of default, giving the prime contractor the right to terminate, take over the work, complete it with another sub, and back-charge the abandoning sub for excess completion costs. Notice and cure provisions are typically required — usually 48 to 72 hours of written notice giving the sub a chance to remedy — unless the subcontract permits immediate termination for emergency or safety reasons. The prime should document the abandonment carefully, mitigate damages by procuring replacement labor promptly, and preserve the right to recover from the sub's performance bond (if any) or subcontractor default insurance. Termination for default also triggers the prime's right to withhold remaining payments and pursue the sub's surety.

Question 12

How long should I keep records of a completed subcontract?

Accepted Answer

Keep the executed subcontract and related project records for at least the longer of (a) the applicable statute of limitations for breach of contract in your state (typically 4 to 6 years for written contracts), (b) the statute of repose for construction defects (often 6 to 15 years from substantial completion), and (c) any tax recordkeeping requirement. For federal prime contracts, FAR 4.703 requires retention of subcontract files for 3 years after final payment (longer for some categories). Practical best practice is 10 years from project completion, which covers most claims windows in most states. Store records in a way that preserves daily reports, change orders, RFIs, lien waivers, and inspection records — these are the documents that win construction disputes.
