Can a Texas Direct Payment permit holder issue a direct pay exemption certificate to a contractor building a pipeline under a lump-sum contract?

Plain-English summary

A contractor building a pipeline under a lump-sum contract for a customer who holds a Texas Direct Payment permit asked the Comptroller whether that customer could issue a direct pay exemption certificate on the job.

The Comptroller walked through the fundamentals of contractor taxation first: building new structures or repairing/remodeling residential realty makes you a "contractor," and labor for new construction of realty is never taxable regardless of contract type. The contract type then determines how MATERIALS are taxed. Under a lump-sum contract, the contractor is treated as the consumer of all materials it incorporates into the customer's property — meaning the contractor pays sales/use tax directly to its own suppliers when it buys those materials (as well as tax on consumable supplies and any equipment it buys, leases, or rents for the job), and the lump-sum charge billed to the customer is not itself taxed. Because the tax is already collected upstream at the supplier level, the direct pay holder must NOT issue a direct pay exemption certificate on a lump-sum job — there's no remaining materials tax for the certificate to defer. Under a separated contract, by contrast, the contractor is treated as the retailer of the incorporated materials, collecting sales tax from the customer based on the agreed contract price for those materials (the separately stated labor charge stays untaxed) — and it's only in THIS scenario that the direct pay permit holder may issue a direct pay exemption certificate in lieu of paying that materials tax, per Rule 3.288.

Applying this to the taxpayer's facts: since the pipeline contract with the Direct Payment permit holder was a lump-sum contract, the contractor could not accept a direct payment exemption certificate. The letter closes with an important structural point: separated invoices alone do not convert a lump-sum contract into a separated contract. To count as separated, the underlying CONTRACT itself must separately state the materials and labor charges, or specifically require that the invoices separate them — invoice formatting after the fact doesn't retroactively change the contract's classification.

What this means for you

Contractors working for Direct Payment permit holders

Check your CONTRACT's classification, not just your invoice format, before accepting a direct pay exemption certificate. If your underlying agreement is a lump-sum contract, a direct pay certificate is off-limits regardless of how your invoices are itemized — you've already paid (or will pay) the materials tax to your own suppliers.

Direct Payment permit holders hiring contractors

You may only issue a direct pay exemption certificate to a contractor performing a genuinely separated contract. Issuing one on a lump-sum job is improper, since the contractor already bears the materials tax upstream.

Accountants and tax professionals

This letter reinforces a recurring, easy-to-miss trap: businesses sometimes assume that itemizing an invoice after the fact reclassifies a contract from lump-sum to separated. It doesn't — the classification lives in the contract's own terms, and that's what should be reviewed before advising on direct pay eligibility.

Common questions

Q: Can a Direct Payment permit holder issue a direct pay exemption certificate to a contractor on a lump-sum contract?
A: No — on a lump-sum job, the contractor already pays materials tax to its own suppliers, so there's no materials tax left to defer with a direct pay certificate.

Q: When CAN a direct pay exemption certificate be used?
A: Only on a separated contract, where the contractor acts as retailer of the incorporated materials and would otherwise collect sales tax from the customer on those materials.

Q: Does separating charges on an invoice convert a lump-sum contract into a separated one?
A: No — the underlying contract itself must separately state (or require separating) the materials and labor charges for the arrangement to count as separated.

Q: Can other contractors or direct pay permit holders rely on this exact letter?
A: No. This is a Texas STAR letter ruling binding on the Comptroller only for the taxpayer it addresses (34 Tex. Admin. Code Rules 3.1, 3.10); confirm your own contract's classification with a tax professional.

From: Emilio Lerma
To: **
Subject: Separated Contracts

Dear **:

I am responding to your e-mail regarding a lump sum contract to build a
pipeline for a Texas Direct Payment permit holder.

If you are building new structures or are repairing and remodeling residential
realty, you are considered a contractor. The type of contract you execute will
determine how the tax on materials is treated. The labor for new construction
of realty is not taxable.

Under a lump-sum contract, a contractor is considered the consumer of all
materials incorporated into a customer's property. As a consumer, a contractor
must pay tax to suppliers at the time the incorporated materials are purchased.
The contractor also pays sales and use tax on consumable supplies and all
equipment bought, leased, and rented for use on the job. The lump sum charge to
the customer is not taxable. Therefore under a lump-sum contract, the direct
pay holder must not issue a direct pay exemption because the sales tax on the
materials to be incorporated would be paid by the contractor to the supplier of
the materials.

Under a separated contract, a contractor is considered the retailer of all
materials physically incorporated into the realty. As a retailer, separated
contractors must collect sales tax from the customer based on the agreed upon
contract price of the incorporated materials. The separately stated charge for
labor is not taxable. The direct pay permit holder may issue a direct pay
exemption certificate in lieu of the sales tax on the incorporated materials.

Direct payment permit holders may not issue a direct payment exemption
certificate to a contractor performing a lump sum contract. Direct payment
exemption certificates may be issued to contractors performing separated
contracts. See Rule 3.288 concerning Direct Payment Procedures and
Qualifications.

Since your contract with the direct pay permit holder is a lump-sum contract,
you may not accept a direct payment exemption certificate. Separated invoices
do not change a lump-sum contract into a separated contract. The contract must
separately state the charges for the materials from the charges for the labor
or specifically require the separation of charges in the invoices to be
considered a separated contract.

This opinion is rendered based on the facts presented. Other facts though
similar, may yield different results.
