Understanding Form 8829: Your Guide to Home Office Deductions
Okay, so you’re running a business from your home? That’s fantastic! But did you know that you could potentially save some serious money on your taxes by deducting home office expenses? This is where Form 8829 comes in. This form can feel a little intimidating, so let’s break it down together. It’s not as scary as it looks, I promise!
What Exactly is the Home Office Deduction?
Before diving into the specifics of Form 8829, let’s talk about the home office deduction itself. Basically, if you use part of your home regularly and exclusively for business, you can deduct a portion of your home-related expenses. This could be a dedicated room, or a specific area, and isn’t just for working at a desk but also for operating your business. Think of it as the IRS saying, “Okay, your home is also your office, so let’s acknowledge that when it comes to your taxes.”
Who Can Use Form 8829?
Not everyone gets to take this deduction! Here’s who generally can:
- Self-Employed Individuals: This is the most common group. If you run your own business, are a freelancer, or an independent contractor, this is for you.
- Partners in a Partnership: If you’re part of a partnership that operates from your home, you might be eligible.
- Certain S-Corporation Shareholders: If you’re a shareholder who works for the S-Corp in your home office you may be able to take this deduction.
Important Note: Employees who work remotely for a traditional company are generally not eligible for the home office deduction. Unfortunately, tax laws changed in 2017 that suspended this, at least through 2025. If your boss doesn’t require you to work from home or is for the company’s convenience rather than yours, you can’t take the deduction, even though you’re working from home. This is a big change so keep it in mind when doing your taxes.
The “Regular and Exclusive” Use Test
To qualify for the home office deduction, the IRS requires that you meet specific criteria:
- Regular Use: You must use the area for business on a regular basis. It can’t be just an occasional thing.
- Exclusive Use: This space must be solely for business. It can’t double as the guest room on the weekend, or a playroom in the afternoon. If it’s also for personal use then it won’t qualify as a home office for the IRS.
Special Circumstance for Daycares: There’s an exception for daycare providers! If you operate a daycare in your home, different rules apply. You don’t have to use the space exclusively for business, but you still need to meet the regular use test.
How Does Form 8829 Work?
Now, let’s look at how Form 8829 helps you actually figure out how much you can deduct. The form is designed to calculate the business percentage of your home’s expenses.
-
Determining Your Home Office Space:
- You will measure the square footage of your home office area.
- Then measure the total square footage of your home.
- Divide the square footage of the office by the square footage of your home to get a percentage of your home dedicated to business use.
- For example, if your office is 200 sqft, and your home is 2000 sqft, then 200/2000 = 0.1 or 10%. You use that percentage to deduct your expenses.
-
Gathering Your Home Expenses: You will gather up your qualifying home expenses. These typically include:
- Mortgage Interest
- Home Insurance
- Utilities (like electricity, gas, water, internet)
- Repairs and Maintenance
- Depreciation (if you own your home)
-
Calculating Deductible Expenses:
- You’ll multiply all of the above expenses by the percentage determined in step one. For example, if you pay $1000 in monthly utilities and your business percentage is 10% then you can deduct $1000 * 0.1 = $100 as a business expense.
- The form helps you organize and calculate these expenses.
-
Limits on the Deduction: There are limitations on how much you can deduct.
- Your home office deduction cannot create a business loss. This means the deduction can’t be more than your business income.
- If your deduction is limited, you can carry over the disallowed amount to future years.
The Simplified Option
Good news! The IRS offers a simplified option for claiming the home office deduction. Instead of calculating all those detailed expenses, you can use a standard rate of $5 per square foot of your home office, up to a maximum of 300 square feet. That means you can deduct a maximum of $1,500.
This simplified method is generally easier and is a good option for many people, but you should determine which method provides the best outcome for your taxes.
When to Use the Simplified Option:
- You don’t want the headache of tracking every little expense
- You want a quicker calculation
- Your home office is on the smaller side
When to Use the Regular Method:
- You have significant home expenses
- Your business percentage is high
- You want to maximize your deduction.
Form 8829 – Step-by-Step
The form itself is broken down into sections. Here is a very general overview of what you will need to complete the form:
- Part I: Details of your home office. You’ll input the total square footage of your home and the square footage of your home office and calculate the percentage of your home that is dedicated to business use.
- Part II: Direct expenses. Here you put all of your expenses that are incurred that are solely for the business space itself, for example a new paint job or a repair on your home office window.
- Part III: Indirect expenses. This is where you input your expenses associated with the general house expenses, that can be deducted. Some of the most common expenses are mortgage interest, insurance, utilities, repairs, and depreciation. These will be multiplied by the percentage you found in Part I to find the deductible amount.
- Part IV: Calculation of allowable deduction. The form will go through a few other calculations and figure out your deduction.
The exact instructions on the IRS website are the best place to learn how to properly complete this form but always consult with a tax professional before filing.
Common Mistakes to Avoid
- Mixing personal and business use: Remember, the area must be used exclusively for business.
- Forgetting to calculate depreciation: If you own your home, you can deduct a portion of its depreciation. It’s a little complicated, so it might be worth consulting a tax professional.
- Claiming the deduction if you’re not eligible: If you are a traditional employee you are most likely not eligible for this deduction, but there are exceptions, so check to be certain.
- Not keeping detailed records: Keep receipts and records of all home expenses.
- Confusing the simplified method with the regular method: Choose one for the entire year.

- Depreciation: A way to deduct the cost of assets over time. You can deduct a portion of the cost of your home through depreciation.
- Self-Employment Tax: This tax is due for income earned through your business and may be reduced by business deductions like the home office deduction.
