What expenses can a security services company deduct?

Security companies carry expenses that most small businesses don’t, and many of those costs are fully deductible. The challenge is that owners often miss deductions that are specific to the industry because they don’t show up on generic lists of business write-offs.

Uniforms and branded apparel are deductible, including patches, badges, name plates, and any alterations. If you provide uniforms to employees, the full cost is a business expense. Cleaning and maintenance of those uniforms counts too. Body armor and protective gear fall into the same category.

Firearms, holsters, ammunition, duty belts, flashlights, handcuffs, batons, pepper spray, and tasers are all deductible equipment expenses. For armed security companies, these costs add up fast. If firearms are used exclusively for business, the full purchase price is deductible. Ongoing maintenance, cleaning supplies, and storage costs qualify as well.

Licensing and training are significant line items in this industry. State guard agency licenses, individual guard cards, firearms permits, CPR and first aid certifications, de-escalation training, and continuing education are all deductible. If you pay for employee training or reimburse employees for licensing fees, those are business expenses too.

Vehicle expenses hit hard for patrol companies. You can deduct actual expenses like fuel, maintenance, insurance, and depreciation on patrol vehicles. Vehicle wraps and light bar installations count. If guards use personal vehicles, you can reimburse mileage at the IRS standard rate and deduct that reimbursement.

Insurance premiums deserve special attention because they tend to be one of the largest expenses a security company carries. General liability, professional liability, workers comp, and commercial auto insurance are all deductible. Armed security companies pay significantly higher premiums, which makes tracking and deducting every dollar even more important.

Background checks and drug screenings for new hires are deductible. So are the costs of posting job listings. Given the turnover rates in the security industry, these recruiting costs can be substantial over the course of a year.

Guard management and scheduling software, two-way radios, GPS tracking systems, surveillance equipment, and mobile reporting apps are all deductible. Communication equipment in particular is easy to overlook because it often gets purchased piecemeal throughout the year.

Other commonly missed deductions include bonding costs, alarm monitoring fees if you provide that service, office and dispatch space, and professional memberships like ASIS International. If you bid on contracts, the costs of preparing proposals and any required bid bonds are deductible.

The key is capturing all of these expenses consistently throughout the year rather than scrambling at tax time. Facility service companies like security firms benefit from having a chart of accounts built around their actual cost structure so nothing slips through the cracks. Working with Dodge County bookkeepers who understand your industry means your books reflect the true cost of operations and you’re not leaving deductions on the table.

More Questions

How do I allocate supplies across multiple cleaning jobs?

For standard cleaning supplies, per-job allocation usually isn't worth the effort. Expense them as a general direct cost. Only track supplies to specific jobs when you're using specialty products where the cost is significant enough to affect job profitability.

How do residential cleaners handle customer deposits?

Customer deposits are liabilities, not revenue. Record them in an unearned revenue account when you collect the money, then move the amount to revenue only after the cleaning is completed.

Read answer

Should an engineering firm use project-based or hourly billing?

It depends on how well-defined the scope is. Fixed-fee billing works best for repeatable deliverables with clear boundaries, while hourly billing protects you on open-ended or consulting work. Most engineering firms use both.

How do I calculate gross profit margin on a janitorial contract?

Subtract your direct costs (labor, supplies, travel, and equipment depreciation) from the contract revenue, then divide by revenue. Most janitorial operators target 30-40% gross margin to cover overhead and leave room for profit.

Do I need to 1099 my subcontractors as a roofer?

Yes, in most cases. Any individual or single-member LLC you paid $600 or more via check or ACH during the year needs a 1099-NEC. Corporations are generally exempt.
