What if the desk you’re sitting at right now could save you up to $1,500 a year in taxes? Most business owners skip this deduction because they think they don’t qualify, or they’re worried the IRS will come knocking. 

The truth is, the home office deduction is legitimate, simple to calculate, and available to most entrepreneurs.

Let’s break it down. 

How the Home Office Deduction Works

A client once told me the home office deduction wasn’t worth the time. 

In just 30 minutes, we calculated their deduction, and it came out to $3,200. This saved them $1,100 in taxes. That’s the equivalent of earning over $2,200 per hour.

The home office deduction is a tax break for people who run a business from home.

If you use part of your house, like a room or a corner, only for your business, you can deduct some of your housing costs on your taxes.

This means you can write off part of your:

• Rent or mortgage
  
• Utilities (electricity, internet, water)
  
• Property taxes
  
• Insurance
  
• Repairs and maintenance

In short, if you have a dedicated area in your home for work, you can turn some of your home expenses into tax savings.

Who Qualifies for the Home Office Deduction?

Over 90% of small business owners we talk to qualify. Here’s what the IRS requires:

1. Regular and Exclusive Use

• You must use the space regularly for business.
  
• The space must be used only for business (no mixing with personal use).
  

2. Principal Place of Business

• If you meet clients, customers, or patients at your home office, you qualify.
  
• Even if you have another office elsewhere, you can still qualify if you use your home office for substantial administrative or management activities (like bookkeeping, emails, and planning).
  
  

Two Ways to Calculate Your Deduction

The IRS gives you two methods. 

1. Simplified Method

• $5 per square foot, up to 300 sq. ft.
  
• Maximum deduction: $1,500.
  
• Easiest option with little recordkeeping.
  

2. Actual (Regular) Method

• Add up all home costs: mortgage interest, rent, property taxes, insurance, utilities, HOA dues, repairs, depreciation, lawn care, and security.
  
• Multiply by the business-use percentage: (home office sq. ft. ÷ total home sq. ft.).
  
• Example: 200 sq. ft. office in a 1,600 sq. ft. home = 12.5%. If your total home costs were $31,800, your deduction would be $3,975.
  
  

The actual method takes more effort but often produces a bigger deduction.

Where to Take the Deduction

• Sole Proprietors and Single-Member LLCs: Report on Schedule C. Use the simplified calculation directly, or file Form 8829 if using the actual method.
  
• S Corporations: Use an accountable plan. The S Corp reimburses you for the home office, creating a business deduction on the return and tax-free income for you.
  
  

Common Mistakes to Avoid

• Mixing personal and business use in the same space
  
• Not documenting square footage, expenses, and purpose
  
• Forgetting that equipment (computers, desks, cameras) is deducted separately, not through the home office deduction
  
  

Bonus: Unlocking the Mileage Deduction

Here’s a hidden perk. If your day starts and ends in your home office, trips to and from another office are no longer considered commuting (which isn’t deductible). Instead, they become business mileage, adding even more savings.

Bottom Line

The home office deduction is one of the simplest and most overlooked ways to cut your tax bill. Remember:

• Two rules: regular and exclusive use, principal place of business.
  
• Two methods: simplified ($5 per sq. ft.) or actual (business-use percentage).
  
  

Take 30 minutes to measure your space, choose your method, and document your expenses. You could be saving hundreds or thousands of dollars every year.

What if I told you that the desk that you are sitting at right now could be worth up to $1,500 a year in tax savings? And the crazy thing is most small business owners skip it because they think they don't qualify, or they're scared that the IRS is gonna come knocking. Today I'm breaking down the home office deduction and the two rules that you have to meet, the two ways to calculate it, and some of the mistakes that we see that can cost you money.

By the end, you'll know exactly how to turn your workspace into a money saving machine, the legal way.

Why the Home Office Deduction Matters

[00:00:49] Let's break down this idea of a home office. I wanna tell a little bit story. I was talking to a client many years ago, and the client says that this home office deduction, this idea of a home office deduction, it just takes too much time and is really not enough benefit.

Oh, and by the way, the IRS isn't like it is what they told me. So I talked with this client. I sat down, I asked a few questions. We spent maybe 25 minutes gathering information, and in less than a half an hour we created the home office deduction, we calculated it. We determined what that home office deduction was, and it equaled $3,200, which saved them over $1,100 in tax savings.

Imagine how powerful that can be. And so for those of you that are understanding, okay, what is the benefit of a home office deduction, really it's turning after tax spending into pre-tax spending, which I talk about all the time. These are expenses that you're gonna have no matter what. Whether you own a business or not, you're gonna have a home and you're gonna be paying for this home. But now as a business owner, you get a deduction for a portion of those expenses, the portion that you use for your business.

[00:02:05] In that example above, it took 30 minutes to determine what part of their home would qualify as a home office deduction, how much of that home qualified, as well as to add up the expenses that occurred throughout the year. That produced $1,100 in tax savings, which at an hourly rate is over $2,200 per hour.

[00:02:31] By the end of this, you'll know if you qualify for the home office deduction and how to claim it. And for those of you scared of the IRS coming after this, this is black and white in the IRS code. The IRS wants you to take advantage of this, they just don't want you to abuse it.

What is the Home Office Deduction?

[00:03:00] Basically, the home office deduction is taking a pre-tax deduction under your business for the business use of your home.

[00:03:08] This could apply whether you own your home, rent your home, whether it's an apartment, house, or condo. If you are paying to live somewhere and you use a portion of that place for your business, then you can potentially qualify.

[00:03:24] Over 90% of business owners we talk to qualify for a home office deduction. You can even qualify if you have an office outside of your home where you do normal client work, as long as you meet a couple of qualifications.

Qualification Rules

Rule 1: Regular and Exclusive Use

[00:03:57] Regular means you use the space regularly. If you walk into the space once a quarter, that’s not gonna qualify. It has to be part of your regular business duties.

[00:04:13] Exclusive means there is no personal use of the space. If you do business on your dining room table but also eat meals there, that’s not exclusive use. But if you have a dedicated bedroom or corner that you only use as your home office, that qualifies.

[00:04:53] The IRS allows exceptions such as walk-through areas or a corner of a studio apartment, as long as that area is exclusively used for business.

Rule 2: Principal Place of Business

[00:05:27] If clients, customers, or patients come there, you meet the requirement.

[00:06:13] If you have a separate physical office, it can still qualify under the administrative or management office rule. If you use your home office for substantial administrative or management activities, and you don’t do those elsewhere, it qualifies.

[00:07:42] So the rules are:

1. Regular and exclusive use
   
   
2. Principal place of business
   
   

Calculation Methods

[00:09:09] There are two methods: the simplified method and the actual method.

Simplified Method

[00:09:26] You get $5 per square foot, up to 300 square feet, for a maximum of $1,500. Easy to record, but capped at $1,500.

Actual Method

[00:10:12] Add up all home costs: mortgage interest, property taxes, rent, insurance, utilities, HOA dues, repairs, depreciation, lawn care, garbage, security, etc. Then multiply by your business use percentage.

[00:11:12] Example: total costs $31,800. Home office is 200 sq. ft. of a 1,600 sq. ft. home = 12.5%. Deduction = $3,975.

[00:12:27] Simplified method is easier. Actual method can provide larger deductions.

Where to Take the Deduction

[00:12:57] If you are a sole proprietorship or single-member LLC (no S Corp election), take it directly on Schedule C.

[00:13:41] If you are an S Corporation, you cannot take it on the S Corp return. Instead, set up an accountable plan. The S Corp reimburses you for the home office. That creates a business deduction on the S Corp return and tax-free income to you.

Common Mistakes

[00:14:35]

1. Using the office space for personal activities.
   
   
2. Not documenting measurements or expenses.
   
   
3. Misunderstanding the principal place of business rule.
   
   
4. Confusing equipment costs with the home office deduction (equipment is a separate 100% business deduction).
   
   

Wrap Up

[00:17:18] Two rules: regular and exclusive use, and principal place of business.
Two methods: simplified method ($5 per sq. ft. up to 300 sq. ft.) and actual method (business percentage of total home expenses).

Annual savings can be significant. Example: $4,000 deduction annually can save $1,500 in taxes for half an hour’s work. The home office deduction can also unlock the mileage deduction. If you start and end your day in your home office, trips to and from another office can become deductible business mileage.

Measure your workspace, choose your method, track expenses, and document everything. Whether you’ve got a fully dedicated office or just a small nook, the home office deduction can put hundreds or thousands of dollars back in your pocket each year.
