Insurance is usually the largest deductible expense for security companies, especially those providing armed guard services. General liability, workers’ compensation, professional liability, and commercial auto premiums can add up to tens of thousands per year. Armed security operations pay significantly more for coverage than unarmed services, and every dollar of those premiums is deductible. If you carry an umbrella policy on top of that, same thing.

Uniforms and protective equipment are fully deductible. This includes shirts, pants, jackets, badges, patches, body armor, duty belts, and boots. Cleaning and maintenance costs for uniforms also count. If you provide branded gear to your guards, that’s a business expense whether you purchase or lease it.

Firearms, ammunition, holsters, safes, and gun cleaning supplies are all deductible for armed security operations. So is range time used for training and qualification. These costs are easy to overlook because they often come out of pocket at retail shops and ranges without formal invoicing. Track every purchase.

New York State requires security guards to complete pre-assignment training, on-the-job training, and annual in-service training. The costs you pay for guard training and NY State Security Guard licensing fees are deductible. This includes the application fees, fingerprinting, and any courses required to maintain compliance. If you send supervisors to additional certifications like CPR, first aid, or fire safety, those qualify too.

Vehicle expenses for patrol cars and response vehicles are deductible. You can use actual expenses including fuel, maintenance, insurance, and depreciation, or the standard mileage rate. For a company running marked patrol vehicles, the actual expense method almost always makes more sense. GPS tracking systems and dashcams installed in those vehicles are deductible as well.

Background checks and drug testing are legitimate business expenses that security companies run constantly. Pre-employment screening, periodic re-checks, and any third-party verification services you use all count. These add up quickly when you’re onboarding guards regularly.

Guard management and scheduling software is deductible. Platforms like TrackTik, Silvertrac, or Birdseye help with shift scheduling, incident reporting, GPS check-ins, and client reporting. Monthly subscription fees, setup costs, and any hardware like checkpoint tags are all deductible. Communication equipment including two-way radios, earpieces, chargers, and repeaters also qualifies.

Bonding costs deserve attention. Many NYC contracts require your company to be bonded, and those bond premiums are a deductible business expense. The same goes for any permit or registration fees the city or state requires you to maintain.

The problem most security companies run into is that these expenses get lumped together or missed entirely on a basic profit and loss statement. When uniforms, background checks, and licensing fees all land in “miscellaneous” or “other expenses,” you lose visibility into your actual cost structure and risk missing deductions at tax time.
