New York Prompt Payment Act: How Contractors Get Paid Faster on Public Projects

Getting paid on time is one of the biggest problems contractors and subcontractors face in New York. Late payments hurt cash flow, delay payroll, and put real strain on a business. On public construction projects, the New York Prompt Payment Act is designed to fix that.

This contractor‑focused guide explains how the Prompt Payment Act works, who it applies to, and what you can do when payment is late—without legal jargon or fluff.

What Is the New York Prompt Payment Act?

The New York Prompt Payment Act sets mandatory deadlines for payment on public construction projects. It applies to state agencies, municipalities, school districts, and public authorities.

The goal is simple: stop payment games, keep money moving down the chain, and give contractors real leverage when payment is delayed.

Who the Prompt Payment Act Protects

The Act applies to public projects only and covers:

• Prime contractors hired by public owners

• Subcontractors at all tiers

• Suppliers providing labor or materials for public work

Private construction projects are not covered. On private jobs, payment rights depend on contract language and other remedies like mechanic’s liens.

Prompt Payment Deadlines Contractors Should Know

Once a proper invoice is submitted:

• Public owner → contractor: Payment due within 30 days

• Contractor → subcontractor: Payment due within 7 days after receipt

• Final payment: Due within 30 days after project completion and acceptance

Missing these deadlines can trigger statutory interest.

What Counts as a Proper Invoice?

Payment deadlines only start after a proper invoice is submitted. In general, that means:

• Clear description of work performed or materials supplied

• Dates of work or delivery

• Contract or purchase order number

• Amount billed

• Required backup documents

Incomplete invoices delay payment. Clean paperwork gets paid faster.

What to Do When Payment Is Late

If payment doesn’t show up on time:

• Send a written demand citing the Prompt Payment Act

• Assert interest on the overdue amount

• Escalate through the public agency if applicable

• Consult counsel before delays turn into serious losses

• Good documentation—contracts, invoices, emails—wins payment disputes.

  
  

Interest on Late Payments

The Prompt Payment Act allows interest on late payments, often up to 1% per month (12% annually) unless otherwise governed by law or contract. Interest is leverage. Use it.

Common Prompt Payment Problems (Real‑World Examples)

Late Subcontractor Payment A prime contractor gets paid by a public owner but delays paying a subcontractor. After seven days, interest begins accruing and the subcontractor can enforce payment.

Invoice Rejected A contractor submits an invoice missing required backup. The payment clock doesn’t start until it’s corrected—one of the most common (and avoidable) causes of delay.

When the Prompt Payment Act Does Not Apply

The Act does not cover private projects. For private work, contractors must rely on:

• Strong contract payment clauses

• Interest provisions

• Mechanic’s liens

• Breach of contract claims

  
  

If the contract is weak, enforcement is harder.
