Is charging a client to integrate their software onto a company's web-hosting server a taxable data processing service, and does the seller's cash-basis sales tax reporting matter?

Plain-English summary

A company that generally keeps its books on the accrual method, but uses the cash method for sales tax collection/remittance, had a professional services engagement to integrate a client's software onto the company's internet site, plus separate web-hosting and maintenance components. Believing the integration work was a nontaxable "professional services" engagement, the company billed the large project in phases without ever charging, collecting, or remitting sales tax on it. The company asked the Comptroller to confirm the integration piece really was nontaxable, and if not, when tax should be paid.

The Comptroller disagreed with the "pure professional services" characterization. Because the integration charges were for placing the client's software on the company's own server — and no software was actually sold to the client — the integration work was found to be solely related to and performed in connection with the company's taxable data processing service (i.e., the web hosting/data storage). As such, the integration charges are part of that taxable service, not a stand-alone nontaxable professional-services engagement. The letter notes that 20% of data processing service charges are excluded from the tax base for services performed on or after October 1, 1999 — so the practical tax base is 80% of the total charge, not the full amount.

On the accounting-method question: Rule 3.302(a)(1) confirms retailers may use a cash basis, an accrual basis, or any other generally recognized accounting method that correctly reflects their business operations for sales and use tax reporting — but a retailer wanting to use something other than a pure cash or accrual system, or an uncommon accounting system, needs prior written Comptroller approval. If the company reports on a cash basis (as it apparently did here), it owes tax when it actually collects the taxable amounts from its customer — meaning back taxes on this project would be measured against when payments were actually received, not when the invoices were issued.

What this means for you

Web hosting, integration, and IT services companies

Don't assume that calling something "professional services" makes it nontaxable if it's really tied to a taxable data processing service like web hosting. If your integration/setup work exists to get a client's software running on your own server as part of a hosting arrangement, expect the whole engagement (minus the 20% data-processing exclusion) to be taxable, not just the hosting fee.

Companies with large, phased engagements spanning taxable and nontaxable components

Break out genuinely separate components (like this contract's hosting/maintenance vs. integration) clearly, but recognize that "professional services" framing doesn't automatically exempt work that's substantively part of a taxable data processing engagement.

Accountants and tax professionals

Two independent takeaways here: (1) the 20% data-processing exclusion (post-October 1, 1999) applies to the taxable base for services like this integration/hosting arrangement, and (2) Rule 3.302(a)(1) permits cash, accrual, or another generally recognized method for sales tax reporting, but any non-standard system needs prior written Comptroller approval — relevant when calculating any back-tax exposure on a project like this one.

Common questions

Q: Is software integration for a web hosting client taxable in Texas?
A: Yes, if the integration is performed in connection with placing the client's software on your own server as part of a taxable data processing/hosting service — even though you're not selling software to the client.

Q: How much of a data processing charge is actually taxed?
A: 20% of data processing service charges are excluded from the tax base for services performed on or after October 1, 1999, so 80% of the charge is generally taxable.

Q: Can a retailer use the cash basis for sales tax reporting even if its books are kept on accrual?
A: Yes — Rule 3.302(a)(1) allows retailers to use a cash basis, accrual basis, or other generally recognized accounting method for sales tax purposes, though a non-standard system requires prior written Comptroller approval.

Q: If tax is owed retroactively, when is it measured from?
A: For a retailer on the cash basis, tax is reported when the taxable amounts are actually collected from the customer, not when billed.

Q: Can any web hosting or IT company rely on this specific letter?
A: Not directly. 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 structure and accounting method with a tax professional.

Original ruling text

January 17, 2001

Dear **:

Thank you for your recent letter concerning sales tax reporting procedures.

Your company uses the accrual method of accounting. However, for purposes of
collecting and remitting sales tax, the cash method is used. You have entered
into a professional services agreement for one of your clients to integrate
your client's software to their Internet site. The custom programming you are
performing does not create any software the client will own. The contract also
includes hosting of their website and maintenance, which are separate
components of this engagement and will be taxed as this service is incurred.
The integration consists solely of professional services. Due to the large size
of this project, you have been billing the client in phases. Since professional
services are not subject to sales tax, you have not billed, collected or
reported sales tax on this contract. It is your view that the integration
component of this contract is a professional services engagement that is not
taxable. You ask that I determine if the contract is taxable and, if so, when
any taxes should be paid.

Response. Your "integration" charges appear to be for placement of your
client's software on your server. In doing so, you will not sell any software
to your client. The integration appears to be solely related to and performed
in connection with the taxable data processing (web hosting or data storage).
As such it is part of the taxable service. As you may be aware, 20% of data
processing services are excluded from the tax base when performed on or after
October 1, 1999.

If you are on the cash basis of reporting for sales tax, you would report tax
when the taxable amounts are collected from your customer. Rule 3.302(a)(1)
states; "for sales and use tax purposes, retailers may use a cash basis, an
accrual basis, or any generally recognized accounting basis that correctly
reflects the operation of their business. Retailers who wish to use an
accounting system to report tax that is not on a pure cash or accrual basis or
that is not a commonly recognized accounting system should obtain prior written
approval from the comptroller. "

different facts, the opinion may change. You may call me toll free at
