Is a Home Security System Tax Deductible?

Most people can’t deduct their home security system from their taxes, but there are ways a security system can help you save. First, you can often get a discount on your home insurance if you buy a security system. And second, security systems pay for themselves if you think about what they protect: Yourself, your family, and your most valuable possessions. Here are our favorites:

When a Home Security System Is Tax Deductible

Of course, there are some exceptions if you want to write off your home security system expenses. We outline them below.

  • Home use vs. business use: If you use your home for business, then you may be able to deduct your home security system. However, this only applies if your home is the principal place of business, so it doesn’t apply to remote employees of larger organizations. Your home needs to be the main place where you meet and deal with customers, clients, or patients (detached structures on your property count as well).1 The security system must cover all of the doors and windows in your home, and you can only deduct the part of the system covering your place of business. You can also deduct any expenses you incurred to monitor or maintain the system. Most people will do a depreciation deduction for the cost of the security system relating to their office, or where they do business exclusively.2

FYI: Getting one of the best home security systems for business is a great way to work from home safely, but be sure to check whether you need a permit for your home security system.

  • Rental properties: If you rent a home to do business in, you can deduct the cost of the security system you use there. Again, this rental needs to be your primary place of business. Learn more about the best home security systems for renters.
  • Detached buildings: Some people work on their properties but in detached buildings like garages (or, if you’re like us, a garage with a smart door that you can control remotely). If that’s the case, you can deduct expenses related to its furnishings and structure, given you use it exclusively and regularly for your business.3

Deduction Limits

If you use part of your home, rental, or detached structure exclusively and regularly for business, you’ll be able to deduct your home security system, but only partially. For example, if you have a security system installed throughout your home, including your office, you can only deduct the equipment, monitoring, and maintenance in your office as a percentage of your entire house. You can calculate this percentage by either comparing your office’s square footage to your home’s total square footage or counting the rooms.

How To Save Money on a Home Security System

The cost of home security systems can get pretty high, depending on how much coverage and monitoring you want. However, aside from a tax deduction, there are several ways to save:

Did You Know: Nearly half of U.S. adults have had packages stolen from their homes, according to our Black Friday package theft study. One way to save money is to avoid package theft by implementing security systems, security cameras, or video doorbells or by having packages sent to Amazon lockers rather than your home.

  • Choose long-term contracts. If you’re signing up for professional monitoring or paid storage, signing a longer contract can help you save money versus a month-to-month option.
  • Only secure entry points. One way to save money on your home security system is to buy less equipment, securing only your doors and windows.
  • Only cover the first floor. While it’s safer to include security sensors on your second-floor doors and windows as well, your first floor will be sufficient, most likely. After all, it’ll be hard for thieves to access your second floor without going through the first, unless you have an outdoor second-story porch that’s easily climbable.
  • Self-monitor. If you’re OK with taking 100 percent of the responsibility for your home’s security, you can get a home security system with no monthly fees. You’ll self-monitor your system for free, paying for equipment only.
  • Use no cameras or cheap cameras. You can either opt for just sensors and no cameras or buy cheap security cameras. The cheapest cameras we’ve tested out are from the company Wyze, whose indoor security cameras start at just $20. Learn more about Wyze camera pricing.

  • Buy an affordable system. Systems can range from around $30 for a single sensor to hundreds of dollars for more involved packages. However, there are many affordable security systems on the market, so you don’t need to spend a ton on equipment.
  • Check for military or senior discounts. Many companies offer discounts for seniors or those in the military, so check for these before purchasing if you’re in one of these groups.
  • Get a discount on homeowner’s insurance. Even if you can’t deduct your home security system from your tax return, you can probably get a discount on your homeowner’s insurance, ranging from 2 to 15 percent total. On average, that saves homeowners $310 a year!5


So there you have it, the lowdown on deducting your home security system from your taxes. Doing your taxes is usually not a straightforward process, and if you work out of your home, it may be even more complicated. The easiest way to make sure you’re getting all the deductions you deserve, if you’re not using an accountant, is to use tax software. We use TurboTax, personally, although there are many other free and affordable options on the market. These days, nearly everything is automated, so why shouldn’t your taxes be as well?
