The trend: security spending is no longer optional
A Wall Street Journal report describes how security budgets have expanded following heightened concerns around executive protection, physical security upgrades, and cybersecurity. While the story focuses on large companies, the same spending categories show up in small businesses—just at a different scale.
- Hiring security consultants or risk assessors
- Installing cameras, access control, monitoring, or alarm systems
- Paying for cybersecurity software, monitoring, or incident response support
- Meeting insurance-related compliance or vendor requirements tied to security controlsPrimary source

How the IRS looks at security costs
Most security spending falls under the general rule for business deductions: expenses must be ordinary and necessary to be deductible. In plain English, the expense should be common in your industry and helpful to your business operations.
Good news
Many security and cybersecurity costs are ordinary operating expenses and can be deductible in the year paid.
What causes issues
Misclassifying equipment as an expense, failing to document business purpose, or treating personal protection like a business cost.

1) Deductible security expenses (most common)
Many security-related services are typically deductible when they support business operations, including:
- Contracted security services and guard services
- Cybersecurity subscriptions, monitoring, and managed security services
- Risk assessments and security consulting
- Alarm monitoring and response servicesPlanning note
Keep invoices, contracts, and a short internal memo showing why the expense is business-related. Good documentation lowers audit risk.
2) Capitalized security costs (timing matters)
When security spending creates or improves an asset, it may need to be capitalized and recovered through depreciation rather than deducted immediately. Common examples include cameras, access control systems, and physical infrastructure upgrades.
- Surveillance camera systems
- Secure access installations
- Reinforced doors or controlled-entry infrastructureWhy small businesses get stuck
They expense everything in the year paid without separating equipment (asset) from monitoring/service (expense). That can create reclassifications later.
Depreciation reference

3) Executive security can trigger taxable income
This is where many businesses make avoidable mistakes. If security is provided primarily for personal protection, the IRS may treat it as a taxable fringe benefit to the individual—similar to additional compensation.
More likely taxable
Personal bodyguards without a documented business risk, security tied to lifestyle, or no policy/risk assessment supporting necessity.
More defensible
Documented business-related security need, company policy, and independent risk assessment supporting the business necessity.

4) Cybersecurity costs and 2025 compliance reality
Cybersecurity is one of the most common “security spend” categories for small businesses. Tax treatment often depends on what you’re purchasing:
- **Software subscriptions and monitoring:** typically operating expenses
- **Breach response and remediation services:** often deductible (facts matter)
- **Hardware/system upgrades:** may require capitalization and depreciationQuick win
Ask your bookkeeper to separate “Cybersecurity (software/services)” from “IT equipment (assets)” so tax reporting is clean at year-end.
2025 planning checklist for small businesses
Before filing your 2025 return, confirm these items are handled correctly:
- Security costs are split correctly between **expense vs. depreciable asset**
- Any owner/executive security has **documented business justification**
- Depreciation elections are aligned with **cash flow and taxable income**
- Cybersecurity costs are classified consistently (software vs hardware vs improvements)
- Payroll/fringe benefit rules are considered where security could be personalNot sure if your security spend is deductible—or creating payroll exposure?
Security costs can lower taxable income, but the classification and documentation have to be clean. If you want a quick review, we can help you separate expenses vs assets, flag any fringe benefit risk, and set up categories that make your 2025 filing smoother.
In a short call, we can: identify what’s deductible now vs depreciable, reduce audit and reclassification risk, and clean up bookkeeping categories for 2025.
Best for: owners, professional firms, closely held companies, and businesses with upgraded systems or executive protection spending.
