Tax-Exempt Construction Materials in Tennessee:How Contractors Assume the Exemption Applies—And End Up Paying for It Anyway

By: Benjamin Adams

A Hypothetical

From April 1 through August 29, 2025, Timber Lake Builders handled a $2.4 million renovation of a Shelby County community center owned by a 501(c)(3) nonprofit. Everyone assumed the same thing: because the owner was tax-exempt, the material purchases would be too. They were wrong.

Timber Lake Builders purchased materials in its own name—some through company accounts, others by employees using that same assumption. By project closeout, most costs were paid and no one had addressed tax. That is often when the problem surfaces.

In Tennessee, a tax-exempt owner does not automatically make construction materials tax-exempt. Contractors are frequently treated as the taxable user and consumer. The result is lost margin, accounting issues, or disputes over who should have carried the tax.

The Basic Tennessee Rule

The key issue is purchase structure—not owner status.

Tennessee recognizes exemptions for certain entities under Tenn. Code Ann. § 67-6-322. But this does not create a blanket exemption for all construction materials. When materials are installed into real property, the contractor is usually treated as the user and consumer, and therefore owes the tax.

So the real question is:

•       Who bought the materials?

•       Who paid for them?

•       Who held title?

A project can involve an exempt client and still produce taxable purchases.

Why Contractors Get This Wrong

The most common mistake is assuming “exempt owner = exempt materials.”

In Tennessee, that is not enough. If the contractor buys and installs the materials, the contractor is typically taxed—even on nonprofit jobs. Even “owner-furnished” materials are not a guaranteed solution. The state focuses on the actual transaction structure, not labels.

The Narrow Exceptions That Actually Matter

Church construction

Church projects may qualify for exemption if the church is the purchaser, pays directly, and holds title. If the contractor is the buyer, the exemption usually fails.

Private nonprofit colleges and universities

Direct purchases by qualifying institutions may exempt the state portion of tax—but contractors may still owe local use tax.

Direct federal purchases

The exemption applies only when the federal agency: 

•       Buys directly

•       Takes title directly

•       Pays with public funds

Contractor reimbursement arrangements generally do not qualify.

What Usually Causes the Exemption to Fail

•       Contractor is the buyer

•       Wrong payment source (e.g., personal cards with reimbursement)

•       Invoice trail contradicts intent

•       Overreliance on “owner-furnished” labels

•       Treating exemption certificates as a cure-all

If the purchase structure is wrong, the exemption fails—regardless of intent.

What Needs to Be Verified Before Materials Are Bought

Before materials are ordered, confirm:

•       Purchaser of record

•       Payment source

•       Ownership/title before installation

•       Applicable exemptions (if any)

Failing to align these early leads to consistent (and expensive) issues later.

What the File Should Show

If claiming an exemption, the documentation must support it:

• Purchase order

• Invoice

• Exemption certificate (or federal documentation, if applicable)

• Payment method

• Delivery/title structure

All records must tell the same story. If they don’t, Tennessee will not infer the exemption.

Pass or Fail? Five Real-World Examples

1.     Contractor purchases materials  taxable

2.     Church directly purchases and pays  may qualify

3.     Employee uses personal card  taxable

4.     Federal agency is direct buyer  likely exempt

5.     University direct purchase  partial exemption (state only)

Common Tennessee Mistakes

•       Treating all nonprofit exemptions the same

•       Focusing on owner status instead of transaction structure

•       Relying solely on exemption certificates

•       Addressing tax too late in the project

Contractor Verification Checklist

Before treating materials as tax-exempt on a Tennessee job, check these items:

    Confirm purchaser of record before procurement begins.

    Identify the specific exemption being claimed.

    Do not rely only on the owner’s exempt status.

    Confirm who will pay the vendor and what funds will be used (no personal funds).

    For church jobs, confirm that the church is buying the materials for church-owned property and church use.

    For private nonprofit college or university jobs, confirm whether the result is only a partial exemption.

    For federal jobs, confirm direct agency purchase, direct title, and direct payment with public funds.

    Make sure the purchase order, invoice, certificate, and payment trail all tell the same story.

    Train project managers, field staff, and accounting staff that an exempt project is not automatically an exempt material purchase.

Bottom Line

Tax-exempt construction-material purchases in Tennessee, are real but narrow. Most failures occur because:

•       The contractor purchased the materials

•       The wrong funds were used

•       The documentation did not support the structure

The key rule is simple: exemption depends on how the purchase is made, not who the customer is.
