IRS & Business Best Practices
Capital Improvement vs Repair
In many states (such as New York and New Jersey), capital improvements to real property are exempt from sales tax when backed by a completed exemption certificate (e.g., Form ST-124), whereas repair and maintenance work is taxable (TODO_VERIFY specific state contractor sales tax rules).
Prompt Payment Acts
Federal and many state Prompt Payment Acts mandate payment terms for contractors and subcontractors within specific windows (typically 14-30 days).
Frequently Asked Questions
What must be included on a commercial contractor invoice?
A contractor invoice should include your business and license number, client/general contractor details, project job site address, client Purchase Order (PO) or contract number, clear separation of labor and materials, and payment milestone terms.
How does sales tax apply to construction labor vs materials?
In many states, contractors are treated as consumers of materials, paying sales tax upon purchasing supplies, and do not charge sales tax to the client for capital improvements. In other states, materials billed to the customer are taxable unless a valid exemption certificate (e.g., resale or capital improvement) is provided.
What are Prompt Payment Acts and how do they protect contractors?
Federal and most state Prompt Payment Acts mandate statutory payment timelines (typically 14 to 30 days from invoice submission) for construction projects, entitling contractors to interest penalties if payments are unreasonably withheld.
What is retainage and how is it reflected on an invoice?
Retainage is a percentage (typically 5% to 10%) of the payment withheld by the owner or general contractor until project completion and final punch list sign-off. If retainage applies, show the retainage deduction clearly before the net payable total.
