Updated California Sales and Use Tax Guidance for Construction and Restaurant Equipment Contractors

The California Department of Tax and Fee Administration (CDTFA) has recently updated its guidance on the application of sales and use tax to transactions involving building construction contractors, subcontractors, and restaurant equipment contractors. These updates, published in CDTFA Publication 9, Construction and Building Contractors (February 2025, ¶408-016), provide crucial clarifications that impact tax compliance and financial planning for businesses operating in these sectors.

Key Updates in CDTFA Publication 9

The revised guidance includes significant clarifications regarding how sales and use tax applies to:

1. Material vs. Fixtures vs. Machinery and Equipment
   • Materials: Items that become an inseparable part of real property remain taxable to the contractor at the time of purchase.
   • Fixtures: Defined as items that are accessory to a building and do not lose their identity when installed, fixtures are generally taxable upon sale or installation.
   • Machinery and Equipment: In some cases, these items may be considered tangible personal property, triggering different tax obligations compared to materials and fixtures.
2. Tax Treatment for Subcontractors
   • The new guidelines reinforce that subcontractors should carefully distinguish whether they perform as retailers or consumers of construction materials.
   • If a subcontractor functions as a retailer, they must obtain a seller’s permit and collect sales tax reimbursement from their customers.
   • When acting as a consumer, use tax liability applies at the time of purchase.
3. Restaurant Equipment Contractors
   • The updated publication provides more detailed direction on the treatment of installed restaurant equipment, such as stoves, refrigeration units, and exhaust systems.
   • Certain equipment bolted, cemented, or otherwise affixed to real property may be considered a fixture rather than tangible personal property, altering the tax implications.

Compliance Implications for Contractors

• Recordkeeping: Contractors and subcontractors must maintain clear records distinguishing between materials, fixtures, and equipment to ensure proper tax reporting.
• Contract Structuring: The taxability of a transaction often hinges on contract terms. Understanding whether a job is a lump sum contract (where the contractor is considered the consumer) or a time-and-materials contract (where tax applies differently) is critical.
• Seller’s Permit Considerations: Contractors that sell fixtures or restaurant equipment should ensure they have the necessary seller’s permits and are collecting and remitting tax correctly.
• Audit Preparedness: With increased scrutiny from tax authorities, businesses should proactively ensure that their invoices, purchase records, and sales documentation align with CDTFA guidelines to avoid potential penalties.
• Industry-Specific Considerations: Businesses involved in specialty contracting, such as electrical, plumbing, or HVAC, should review whether recent changes impact how their purchases and installations are taxed.

Next Steps for Contractors and Businesses

With the updated guidance now in effect, contractors and restaurant equipment suppliers should:

• Review Existing Contracts: Determine whether changes in tax treatment necessitate contract modifications or renegotiations.
• Train Accounting Teams: Ensure finance and accounting personnel understand the revised tax treatment to prevent costly compliance errors.
• Consult Tax Experts: Given the complexities of California sales and use tax, consulting a tax professional can help ensure the accurate application of the latest regulations.
• Evaluate Pricing Strategies: Contractors should assess whether tax obligations affect pricing structures and how they present tax-related costs to clients.
• Stay Updated on Future Changes: The CDTFA continues to refine tax policies, so staying informed about future updates can help businesses avoid unexpected liabilities and maintain compliance.

Looking Forward

The CDTFA’s updated guidance offers critical insights into the taxation of construction and restaurant equipment transactions. Contractors and subcontractors should take proactive steps to align their tax practices with the new regulations to avoid compliance issues and optimize tax obligations. The evolving tax landscape highlights the importance of continuous education and strategic financial planning to ensure businesses remain competitive and compliant.
