Is Alarm Monitoring Tax Deductible?

Quick Answer: ✅ Yes — Security alarm monitoring services for business premises are fully deductible as a necessary business operating expense.

The Short Answer

Security system monitoring fees — whether for burglary alarms, fire alarms, video surveillance monitoring, or integrated security services — are 100% deductible business expenses. These services protect business assets and ensure business continuity, making them ordinary and necessary expenses. This includes monthly monitoring fees, installation costs, and equipment rentals.

IRS Rules for Deducting Alarm Monitoring

Under IRC Section 162 and IRS Publication 535, security services qualify as ordinary and necessary business expenses. Alarm monitoring protects business assets (inventory, equipment, data) and ensures business operations can continue without interruption from theft, fire, or other security incidents. The IRS recognizes security as a legitimate business concern, especially for businesses with valuable inventory, sensitive data, or high-risk locations.

How Much Can You Deduct?

Commercial alarm monitoring typically costs $15-100/month depending on system complexity and monitoring level.

How to Categorize in QuickBooks

• QBO Category: Professional Services or Operating Expenses — Security Services
• Schedule C Line: Line 17 (Legal and professional services) or Line 27a (Other expenses — "Security Services")
• Tip: If you also have security guard services, consider separate sub-accounts for "Alarm Monitoring" and "Security Guards" to track different types of security costs.

Common Mistakes to Avoid

1. Not deducting system installation costs. Unless the security system is a major capital improvement (rare for basic alarm systems), installation costs are typically deductible in the year incurred rather than depreciated.
2. Claiming false alarm fines as deductible. Fines and penalties — even for false alarms — are generally not deductible under IRC Section 162(f). Only the monitoring service itself is deductible.
3. Home office users not claiming business portion. If your home office has enhanced security monitoring due to business equipment or records, you may be able to deduct the business portion.

Record-Keeping Requirements

Keep security service contracts and agreements, monthly monitoring invoices, installation receipts, proof of payment, and documentation of business assets being protected. For high-value inventory or equipment, maintain records showing the business need for security monitoring.
