A commercial monitoring company separately bills clients for security-system monitoring and fire-alarm-system monitoring, subcontracting the actual monitoring to its parent company. Are separately stated charges for monitoring a fire alarm system taxable the same way as security system monitoring charges, and what about the telecommunications lines used to run both?

Plain-English summary

This letter is a follow-up clarification on an earlier ruling request. The taxpayer, a Delaware corporation operating in Texas with no offices elsewhere, markets commercial protection monitoring services — burglar alarm and fire alarm monitoring — and also sells monitoring equipment, warranties, and system design/installation, all billed separately from the monthly monitoring charges. The taxpayer subcontracts the actual system design, installation, and monitoring work to its Parent Corporation, which does the monitoring using computer hardware at Parent's Texas location (in a city and MTA taxing district). The taxpayer asked for a ruling on how Texas state and local sales tax applies to its separately stated security-system monitoring charges versus its separately stated fire-system monitoring charges.

The Comptroller's answer draws a clean line: separately stated charges for monitoring FIRE alarm systems are not subject to state and local sales tax, while charges for monitoring SECURITY systems are taxable. The two must be billed and tracked separately to get this split treatment — the ruling is about separately stated charges specifically.

There's a telecom wrinkle on top of that: the telecommunications services Parent uses to perform the monitoring are themselves relevant. Parent may buy the dedicated lines used to perform both fire and security monitoring tax-free for resale, but it must then self-assess and remit sales tax on the portion of that telecom usage attributable to fire alarm monitoring — even though the fire alarm monitoring service itself is nontaxable, the underlying telecom capacity used to deliver it is not automatically exempt just because the end service is.

What this means for you

Commercial security/fire monitoring companies

Bill fire alarm monitoring and security system monitoring as separately stated line items — only the fire alarm monitoring charge itself escapes state and local sales tax, and only if it's genuinely broken out from the security monitoring charge.

Companies subcontracting monitoring to an affiliated parent using shared telecom lines

Buying dedicated telecom lines tax-free for resale doesn't mean all downstream usage stays untaxed — the portion of that telecom capacity used for a nontaxable service (fire alarm monitoring) still requires the buyer to self-assess and remit tax on that portion, separate from how the end monitoring service itself is taxed.

Accountants and tax professionals

A useful two-layer example: (1) fire alarm monitoring vs. security monitoring are taxed differently even within the same commercial protection business, and (2) the telecom inputs used to deliver a nontaxable service can still generate their own separate tax obligation via self-assessment on a resale-certificate purchase.

Common questions

Q: Is monitoring a fire alarm system taxable in Texas?
A: No, when separately stated from other monitoring charges.

Q: Is monitoring a security/burglar alarm system taxable?
A: Yes.

Q: If a company buys telecom lines tax-free for resale to monitor both fire and security systems, does it owe any tax on those lines?
A: Yes — it must self-assess and remit sales tax on the portion of the telecom usage attributable to fire alarm monitoring, even though the fire alarm monitoring service itself isn't taxable.

Q: Can I rely on this letter for my own monitoring business billing?
A: No. It's rendered based on the specific facts presented and can be relied on only by the taxpayer to whom it was issued; other facts, even if similar, may produce a different result.

Citations and references

No specific Tax Code section or numbered Comptroller rule is quoted in the body of this letter; the answer applies the Comptroller's general policy distinguishing taxable security monitoring from nontaxable fire alarm monitoring, and the standard resale/self-assessment mechanic for telecom lines supporting a nontaxable service.

Original ruling text

July 21, 1999

Dear Mr. **:

Thank you for your recent letter which is restated in part with response below.

Thank you for you June 22,1999 response to our request for letter ruling. Based
on your letter and our telephone conversations, clarification of one issue is
requested. For your convenience, I have included a copy of our original letter
ruling request and your reply.

FACTS:

Taxpayer is a Delaware Corporation physically located in Texas. Taxpayer
conducts business from their Texas location and currently has no offices or
employees outside the state. The Taxpayer is an affiliate member of Parent
Corporation ("Parent") which has sales and use tax nexus in all states.

Taxpayer's Business

Taxpayer's primary business activity involves marketing commercial protection
monitoring services ("services") such as burglar and fire alarm monitoring.
Taxpayer may also generate revenue from the sale of monitoring equipment, the
sale of optional warranties, design and installation of monitoring systems and
other contracted services such as loss prevention. Equipment sales, warranty
sales, design and installation of security systems, and other contracted
services are billed separately from the monthly monitoring charges. When
taxpayer bills for design and installation, no segregation is made between
design charges and installation charges. Customers may purchase equipment
directly from the Taxpayer or lease the equipment through a third party leasing
company.

Taxpayer subcontracts security system design, security system installation,
security system monitoring, and other contracted services to Parent. Parent
monitors security systems utilizing computer hardware at the Parent's Texas
location. The Parent is located in a city and MTA taxing district which impose
sales tax. Parent bills Taxpayer for services rendered.

ISSUE:

** requests a ruling on the application of Texas state and local
sales and use tax on separately stated security monitoring services and
separately stated fire system monitoring services.

Response: Separately stated charges for monitoring fire alarm systems are not
subject to state and local sales tax while charges for monitoring security
systems are subject to tax.

I should also point out that the portion of telecommunications services used by
Parent to monitor fire alarm systems will be subject to sales tax. Parent may
purchase dedicated lines used to perform both functions tax free for resale,
but must self assess and remit sales tax on the portion attributable to fire
alarm monitoring.

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