Are asphalt roads subject to state sales tax

As a starting point, it’s important to understand that in most cases, the completed asphalt road itself is not subject to state sales tax. This is because roads are typically considered real property improvements rather than tangible personal property. Real property improvements are generally exempt from sales tax as they become part of the land and are not considered a sale of goods.

However, this general rule is subject to numerous exceptions and variations depending on state-specific regulations, project types, and other factors.

Factors Influencing Taxation of Asphalt Roads

Several key factors determine whether components of asphalt road construction may be subject to state sales tax:

  1. Materials vs. Labor: While the finished road may not be taxable, the materials used in construction might be subject to sales tax in many states.
  2. Contractor Status: The tax treatment can depend on whether the contractor is considered the end-user of the materials or if they’re purchasing them on behalf of a tax-exempt entity.
  3. Public vs. Private Projects: Roads constructed for government entities often have different tax implications compared to those built for private use.
  4. Maintenance and Repair: The tax treatment of road maintenance may differ from new construction, potentially subjecting some repair work to sales tax.
  5. State-Specific Regulations: Each state has its own set of laws and regulations governing the taxation of road construction materials and services.

State-by-State Analysis of Asphalt Road Taxation

I always ensure I’m up-to-date on state sales tax regulations for asphalt roads, as it directly impacts our project budgets and bidding processes. I’ve found that understanding the nuances of tax exemptions for public works projects can save our company significant amounts on material costs. When planning new road construction, I carefully consider how each state’s tax policies might affect our choice of suppliers and overall project feasibility. Let’s examine how different states approach the taxation of asphalt road construction:

Washington State: Rule 171 and RCW 82.04.050

Washington State provides a clear example of how specific a state’s regulations can be regarding road construction taxation. Rule 171 makes clear that only those items that are actually “part of” the road system, its lighting system, or its drainage system are exempt from retail sales tax. This rule, along with RCW 82.04.050, establishes a retail sales tax exclusion for public road improvements.

Key points of Washington’s approach:

  • Items that become an integral part of the road structure are exempt from sales tax.
  • Materials used temporarily during construction but not becoming part of the road may be taxable.
  • The distinction between “part of” the road and auxiliary items is crucial for tax purposes.


California generally exempts materials used in road construction from sales tax when the road becomes part of real property. This approach aligns with the general principle that real property improvements are not subject to sales tax.

New York

New York State exempts road materials from sales tax when used in capital improvement projects. This exemption applies to materials that become a permanent part of the road structure.


In Texas, road construction is considered a non-taxable service. However, contractors may owe tax on materials used in the construction process. This creates a situation where the service is exempt, but the inputs may be taxable.


Florida exempts road materials from sales tax when they become part of real property improvements. This aligns with the state’s general approach to real property improvements and sales tax.


Illinois takes a different approach, generally subjecting materials used in road construction to sales tax. However, certain exemptions may apply, particularly for government projects.


Michigan provides a sales tax exemption for materials used in government construction projects, including roads. This exemption is designed to reduce the cost of public infrastructure projects.

The Benefits of Understanding Asphalt Road Taxation

While the complexity of state sales tax as it applies to asphalt roads may seem daunting, there are several benefits to gaining a thorough understanding of this topic:

  1. Improved Project Budgeting: Accurate knowledge of tax implications allows for more precise cost estimations and budgeting for road construction projects.
  2. Enhanced Compliance: Understanding the specific regulations in each state helps contractors and project managers ensure full compliance with tax laws, avoiding potential penalties or legal issues.
  3. Cost Savings Opportunities: In states with exemptions for certain materials or project types, knowing how to properly apply these exemptions can lead to significant cost savings.
  4. Competitive Advantage: Companies with a strong grasp of tax implications can potentially offer more competitive pricing on projects.
  5. Better Public Resource Allocation: For government entities, understanding tax exemptions for public road projects can lead to more efficient use of public funds.

Best Practices for Navigating Asphalt Road Taxation

To effectively manage the tax implications of asphalt road construction, consider the following best practices:

Consult with Tax Professionals: Work with accountants or tax attorneys who specialize in construction tax law in your state.

Maintain Detailed Records: Keep comprehensive documentation of all material purchases, labor costs, and project details to support tax calculations and potential audits.

Understand Exemption Certificates: Familiarize yourself with any applicable exemption certificates for tax-exempt projects or entities in your state.

Stay Informed on Law Changes: Tax laws can change, so stay up-to-date on any new regulations affecting road construction in your state.

Implement Strong Accounting Practices: Use robust accounting systems that can accurately track taxable and non-taxable expenses related to road construction projects.

Please Note: Terms like “bituminous roads” or “blacktop” may be used interchangeably with “asphalt roads” in tax regulations.

The Future of Asphalt Road Taxation

As infrastructure needs continue to grow and evolve, likely, state tax laws regarding asphalt roads will also change. Some potential future developments to watch for include:

  • Increased standardization: There may be efforts to create more uniform tax treatments across states to simplify compliance for companies operating in multiple jurisdictions.
  • Environmental considerations: As sustainability becomes more important, there may be tax incentives introduced for using eco-friendly materials or construction methods in road projects.
  • Technology impact: The integration of smart technologies into road systems may lead to new tax considerations for these enhanced infrastructure elements.

My journey with asphalt began by studying civil engineering and learning about core pavement materials like aggregate, binder and additives that compose this durable and versatile substance. I gained hands-on experience with production processes including refining, mixing and transporting during my internships, which opened my eyes to real-world uses on roads, driveways and parking lots. Over the past decades, I have deepened my expertise in asphalt properties like viscosity, permeability and testing procedures like Marshall stability and abrasion. My time with respected construction companies has honed my skills in paving techniques like milling, compaction and curing as well as maintenance activities like crack filling, resurfacing and recycling methods. I'm grateful for the knowledge I've gained about standards from Superpave to sustainability best practices that balance longevity, cost and environmental friendliness. It's been an incredibly rewarding career working with this complex material to build the infrastructure future.
