Prompt Payment to Subcontractors: Business and Professions Code section 7108.5 requires a prime contractor or subcontractor to pay a subcontractor its share of each progress payment no later than seven days after receiving that payment, unless agreed otherwise in writing. Violation is a cause for disciplinary action and carries a penalty payable to the subcontractor of 2 percent of the amount due per month for every month payment is not made, with attorney fees and costs to the prevailing party in a collection action. Where there is a good faith dispute the statute allows withholding of no more than 150 percent of the disputed amount. That is a bookkeeping deadline, and it is only survivable if the payables file is already complete when the money arrives.
Statutory Waiver and Release Forms: California prescribes four release forms in the Civil Code: conditional waiver and release on progress payment under section 8132, unconditional on progress payment under 8134, conditional on final payment under 8136, and unconditional on final payment under 8138. Each section provides that the waiver and release is null, void and unenforceable unless it is in substantially the statutory form. A conditional release only takes effect once payment actually clears, while an unconditional release gives up the rights on signature. Knowing which one belongs with which payment, collecting it and filing it against the right job is routine bookkeeping work that quietly protects a lot of money.
Preliminary Notice on the Receivable Side: Civil Code section 8200 requires most claimants who do not contract directly with the owner, including subcontractors, lower tier subs, material suppliers and equipment lessors, to serve a preliminary notice to preserve mechanics lien, stop payment notice and payment bond claim rights, and the notice reaches back only 20 days before it is given. We are not attorneys and we do not serve notices. What we maintain is the record the deadline runs off: first furnishing date, contract and change order amounts, what has been billed, what has been paid and what is being held, by job and by tier.
Public Works Contractor Registration: On California public works, contractors and subcontractors generally must be registered with the Department of Industrial Relations under Labor Code section 1725.5, with registration renewed annually. Labor Code section 1771.1 governs the effect on bidding and award, and a subcontractor's failure to be registered is grounds under Public Contract Code section 4107, with the awarding authority's consent, to substitute a registered subcontractor in its place. Registration status therefore belongs in your vendor record next to the insurance expiry date, checked before award and again before payment, not discovered when a compliance officer asks.
Oakland Construction and Demolition Debris Rules: Oakland requires a recycling plan submitted through the city's online system, 100 percent recycling of materials including asphalt, concrete, rock, sand, gravel, plant debris and clean fill, and a minimum 65 percent recycling rate for other materials. Any service provider transporting C&D debris from an Oakland project must hold a fully executed non-exclusive franchise agreement with the city, and the city assesses fines for missing the recycling rate or using unauthorized haulers or facilities. That turns disposal into a vendor approval question. We check the hauler before the bill is entered and keep the weight tickets attached to the transaction.
Oakland Business Tax Certificate: Oakland requires every person conducting business activity in the city to obtain an annual business tax certificate and pay the business tax, and a business based outside Oakland can still be covered if it does business inside the city, which catches plenty of contractors headquartered elsewhere in the East Bay. Measure T, approved by voters in November 2022, replaced the old business tax chapter with a tiered progressive structure based on gross receipts and business sector, effective January 1, 2023. The bookkeeping answer is to tag revenue with the jurisdiction of the work when the invoice is entered.
Subcontractor Reporting and Worker Classification: For payments made in calendar year 2026 the federal reporting threshold for Forms 1099-NEC and 1099-MISC rose from 600 dollars to 2,000 dollars under the tax law signed in July 2025, indexed for inflation from 2027. The higher threshold does not reduce the record keeping, since you still need accurate vendor totals to know who crosses it, and the income is taxable regardless. Alongside that, California applies a strict test to whether a worker is an employee or an independent contractor, and misclassification is expensive. We collect W-9s before the first payment and track payments by vendor and job all year.
