A company monitors customers' Wide Area Networks (WAN) from Texas for a flat monthly fee per monitored device, occasionally performing remote repairs itself (about 10% of the time) at no extra charge, with other repairs referred to third-party carriers or equipment vendors who bill the customer separately. Is the monthly monitoring charge taxable, does it matter that the customer isn't charged extra when a repair happens, and how does location (Texas vs. out-of-state customers) affect the answer?

Plain-English summary

A network-monitoring company ("ABC") monitors customers' Wide Area Network (WAN) connectivity from its Texas facility, serving customers both in Texas and out-of-state. ABC bills a flat monthly fee per monitored device. When ABC detects a problem, it fixes it remotely itself about 10% of the time (at no extra charge to the customer); the rest of the time it refers the problem to a third-party carrier or equipment vendor, who bills the customer directly and separately for any repair. ABC asked the Comptroller to confirm its tax treatment, specifically arguing that since its monitoring fee doesn't change based on whether a repair happens, the "real essence" of the service is monitoring — so shouldn't the whole charge be nontaxable? It also asked about sourcing rules for out-of-state customers and which address (billing, ABC's location, or the customer's device location) controls local tax.

The Comptroller's answer: it depends on where any repair actually happens, not on how the charge is structured.

• Monitoring related to a repair of a customer's LAN or WAN is subject to Texas state and local sales tax if the repair is performed IN Texas — the fact that the customer isn't billed an extra amount for that repair does NOT change the monitoring charge's tax treatment.
• The same monitoring/repair function is NOT subject to Texas tax when the repair is performed OUTSIDE Texas.

The Comptroller also attached a copy of a prior 1997 letter to the same client, addressing the earlier version of this same monitoring arrangement. That 1997 letter found that pure monitoring charges — where the monitoring company's contract does not call for it to make repairs itself, and any necessary repairs are billed separately by someone else — were not subject to sales tax as a telecommunications service, data processing, or repair of real/tangible property. That 1997 letter flagged one exception: if the monitoring service required the provider to be licensed by the State Board of Private Investigators, the charges would become taxable as a security service.

What this means for you

Network monitoring / managed IT service providers

Whether your monitoring charge is taxable in Texas can hinge on a fact you might not think to track: whether YOUR company (not a third party) performs any repair, and if so, whether that repair happens in Texas. If you occasionally perform in-Texas remote repairs as part of an otherwise flat monitoring fee, the entire monitoring charge tied to that repair becomes taxable — bundling the repair into a flat fee doesn't insulate it. If repairs are always handled and billed separately by a third party (carrier or equipment vendor), your pure monitoring charge may stay nontaxable, per the 1997 letter attached here — unless your monitoring work requires a private investigator license, which flips it to a taxable security service.

Businesses buying network monitoring services from a Texas-based provider

If your provider performs repairs itself as part of the service, ask where those repairs are actually performed — that location, not your own billing address, is what the Comptroller looks to for taxability when a repair is involved.

Accountants and tax professionals

This letter is a useful contrast pair with the attached 1997 letter to the same taxpayer: the same monitoring service can be taxable or not depending on a subtle change in facts — specifically, whether the monitoring company itself performs any of the repair work, and where. It's also a good illustration that "the charge doesn't change based on whether a repair happens" is not a winning argument against taxability once the provider is the one performing repairs.

Common questions

Q: Is a flat monthly network monitoring fee taxable in Texas if the provider occasionally performs remote repairs at no extra charge?
A: Yes, if the repair is performed in Texas — the monitoring charge becomes taxable, and the fact that no separate charge was billed for the repair doesn't change that.

Q: What if the repair happens outside Texas?
A: The same monitoring/repair function is not subject to Texas tax when the repair is performed outside Texas.

Q: Is pure network monitoring (with no repairs performed by the monitoring company) taxable?
A: Per the 1997 letter referenced in this ruling, no — unless the monitoring service requires the provider to be licensed by the State Board of Private Investigators, in which case it becomes taxable as a security service.

Original ruling text

June 21, 2001

Dear **:

Your client, ** (ABC), provides Wide Area Network connectivity
monitoring for their customers.

Once the problem is isolated, ABC will fix the problem remotely, if possible.
This occurs about ten percent of the time. If not, the problem is referred to
the IXC (International Exchange Frame Carrier) for circuit correction, or to
equipment vendors for hardware correction/replacement. All acts are remotely
performed by a third party, there are no direct, on-sight services performed by
ABC. Referrals to equipment vendors is a service that is covered by a
maintenance contract, which will correct the problem at no charge. If the
customer will be charged for the repair, the equipment vendor charges the
customer directly for the repair (not ABC) on a time and material basis.

The cost for the monitoring service is currently invoiced based upon a monthly
fee for each customer device that is monitored. The monthly fee is invoiced
separately to the customer for the monitoring, detection and correction, and
the vendor maintenance contract, if applicable. If ABC performs any repairs,
the customer is not charged for the repairs. The service is performed from your
client's location in CITY A, Texas for customers located both in Texas and
out-of-state. All of ABC's servers are located in CITY A.

You ask that I confirm what portions, if any, of your clients services are
subject to Texas sales tax. You ask "Since our client's charge to monitor the
customer's network is not impacted by the fact that a repair may be performed
(10% of the time), wouldn't the entire charge be non-taxable (i.e., 5% Rule?).
The real essence of the service is to monitor the network." You ask if
customers located out of state would be exempt from sales tax on the total
charges since they would be deriving the benefit outside of Texas? Also, if the
applicable local taxes for sales to Texas based customers is based on client's
billing address, ABC's address in CITY A, and/or the location of the customer's
device?

Response: Monitoring related to a repair of a customer's LAN or WAN is subject
to Texas tax and CITY A city sales tax if the repair is performed in Texas. The
fact that the customer is not charged an additional amount for the repair does
not alter the tax treatment of the monitoring charge. The same function related
to repairs performed outside Texas is not subject to Texas state or local tax.

I am enclosing a copy of a 1997 letter written to your client.

Dear **:

This is in response to your question about the tax treatment of charges for
monitoring a nationwide "Wide Area Network" (WAN) from your facilities in CITY
A, Texas.

The WAN consists of the data communications lines and equipment needed to
connect a customer's "Large Area Network" (LAN) to the WAN. Your firm makes a
single monthly charge for monitoring the WAN. The contract does not call your
firm to make direct or remote software or hardware repairs. Such repairs, if
necessary, are made for a separate charge. The majority of problems encountered
involve third-party carrier facilities in which case, your firm notifies the
affected carrier of the problem.

Your charges for monitoring are not subject to sales tax as telecommunications
service, data processing, or repair of either real or tangible property. Some
monitoring services require the service provider to be licensed by the State
Board of Private Investigators. If that is the case, your charges would be
subject to sales tax as a security service.

On March 4, 1997 you sent me an email saying that you had attempted to reach
them but had been unsuccessful. I was out of the office that week, but
responded the following Monday by email with their telephone number of
463-9922.

This opinion is rendered based on the facts presented. If there are additional
or different facts, the opinion may change.

You may call me toll free at 1-800-531-5441, ext. 3-4680. The direct line is
512/463-4680. You may also write to Tax Policy, Comptroller of Public Accounts.
