The construction industry is currently experiencing a boom. Thanks to strong economic conditions, multiple job opportunities, and investment from the government, the industry is projected to reach $1.8 trillion by 2023.

But in this world, nothing can be said to be certain except death and taxes. As your construction business experiences a boost in revenue, it is important to stay on top of your tax obligations or risk the scrutiny of your state’s tax authorities.

In general, when a buyer purchases something from a seller, the buyer needs to pay the sales tax, while the seller collects the tax and sends it to the relevant tax authorities. In the construction industry, however, dealing with taxes is easier said than done. For something that has a huge impact on the bottom line, rules and regulations about construction sales taxes are rarely straightforward and often confusing.

So before you get hit with an audit and incur the wrath of your state’s tax authorities, here are some general guidelines on how to deal with construction taxes. Note that the following is not intended as a legal ruling but rather a general guide to sales taxes in the construction industry. Consult your state’s revenue services department for specific information.

In general, construction services are not taxed

Most states do not require construction companies to charge a sales tax on services rendered. However, there are some states that require contractors to charge a sales tax on certain types of projects. With the rise of service-based companies, many states are considering the changes in the current business landscape and are beginning to collect taxes on some services.

The states of Alaska, Delaware, Montana, New Hampshire, and Oregon do not impose a statewide sales tax on services. Meanwhile, the states of Hawaii, New Mexico, South Dakota, and West Virginia tax services by default except for services that are specified in their state laws. The remaining 41 states along with the District of Columbia also do not tax services by default, but there are services specified by state laws that are taxed. Because each one of these states taxes different types of services, construction businesses need to review which aspects of their services are taxable and which are not. 

In general, taxability of material purchases depends on the contract

In most states, contractors need to pay a sales tax upon the purchase of materials to be used in a construction project. However, this can get a little tricky. There are a few states that treat contractors as resellers who purchase materials to transform and sell to a buyer depending on the form of contract that they use.

In general, there are two types of contracts in construction:

• Lump-sum contract – With this contract, labor, materials, supplies, overhead, and profit are all “lumped” together in one item amount. 
• Time and materials contract – With this, the stated contract amount is based on separate and itemized charges for supplies and materials and the rate of workers for their services.

Currently, Colorado, Washington, D.C., Indiana, Nebraska, and Texas require contractors to charge sales taxes on the materials section of a time and materials contract. Contractors in these places must also pay a sales tax on the purchase of materials used in lump-sum contracts. Meanwhile, the states of Arizona, Hawaii, Mississippi, and New Mexico require contractors to charge a sales tax for both lump-sum contracts and time and materials contracts.

Consult a tax professional before making a bid

Sales taxes have a huge impact on your bottom line. Depending on the type of contract you use for a project, an incorrect estimate of the sales tax may lead to a bad construction deal. So before you bid on any job, it is always a good practice to consult a tax professional to help you determine crucial information that will aid you in your decision.

It doesn’t hurt to ask questions about the taxability of some of the aspects of your business. For instance, you need to ask whether you will be treated as a reseller on a specific project and therefore need to up your bid to account for sales taxes or not. State laws may also provide exemptions as well as project-specific rules which you need to know reasonably well before making a bid.

Believe me when I say that learning about the numerous taxation rules and regulations is incredibly frustrating, especially for people who are not fluent in legalese. But at the end of the day, your due diligence can help you make better business decisions.
