Home Office Deduction: Who Qualifies and How It Works
The home office deduction is for space you use regularly and exclusively for business. Learn the tests, the two methods and why remote employees differ.
The short answer
What is the home office deduction?
The home office deduction lets some people deduct part of their home costs when they use a space in the home regularly and exclusively for business.
It is meant for people running a business from home, not for anyone who simply works from the couch. The space must be a real part of the home set aside for the work, such as a spare room, a corner that is clearly separate, or a detached studio.
Like other business deductions, it lowers your business profit. For the self-employed, that also lowers the profit used to figure self-employment tax. It does not create a refund from nothing, and it must be supported by your facts.
The tests
Who qualifies for the home office deduction?
To qualify, the space must generally meet two tests: it must be used regularly and exclusively for your trade or business, and it must be your principal place of business or otherwise meet an IRS exception.
"Exclusively" is the test people stumble over. A guest bedroom that doubles as an office, or a dining table you work at during the day, usually does not qualify. There are limited exceptions for things like storing inventory or running a daycare in the home.
Your home can be your principal place of business when you do your administrative and management work there and have no other fixed location where you do substantial work of that kind. Many contractors, consultants and online sellers meet this idea, but the details matter.
- The space is used regularly, not just occasionally
- It is used only for the business, with no personal use
- It is your main place for business or where you meet clients
- It is part of your home, or a separate structure on the property
Employees
Can I deduct a home office if I work from home for an employer?
Generally, employees cannot deduct a home office on their federal return, even when they work from home full time.
For a number of years this deduction has generally not been available to employees. Because the law can shift, we confirm the current rule each year before we prepare a return.
Someone who is self-employed, or has a business as well as a job, may still qualify for the business. If a job and a side business use the same space, only the business use can count. Alabama has its own income tax rules, and we check how the state treats the deduction for you.
Calculating
What is the difference between the simplified and regular methods?
The simplified method uses a flat IRS rate per square foot of qualifying space, while the regular method figures the actual share of your home expenses.
The table gives the general picture. You can usually choose the method year by year, so run the numbers both ways.
| Feature | Simplified method | Regular method |
|---|---|---|
| How it is figured | A set rate times the office square footage | Business percentage of actual home costs |
| Records needed | Square footage of the space | Bills, mortgage or rent, insurance and more |
| Form | Worksheet, included on the return | Form 8829 |
| Depreciation | Not claimed separately | Included for owners |
Both methods have limits tied to the income from the business. The IRS sets the rate and limits, and they can change.
Watch outs
What are the risks and records for a home office deduction?
The main risks are claiming a space that is not used exclusively, and claiming a deduction without records to support it.
Keep the square footage of the office and of the home, photos if you can, and the bills that show your costs. See receipts and expense tracking for a simple way to hold onto them.
If you own your home and use the regular method, part of the depreciation you claim can affect the tax when you later sell. That is an important trade-off, and it is worth understanding before you decide. Our guide on taxes when you sell your home covers the sale side.
The deduction is not a red flag by itself when it is honest and supported. The problems come from overstated space or personal use. Other costs of the business are covered in business expense deductions.

Answers
Questions about home office deduction
Can I claim a home office if I rent?
Yes, renters may qualify if the space meets the tests. The regular method uses a share of rent and utilities, while the simplified method uses square footage.
Does my office have to be a separate room?
Not always, but the space must be clearly identifiable and used only for the business. A defined area can qualify. A shared area that is also used personally usually cannot.
Can I deduct internet and phone with a home office?
Those may be deductible business expenses on their own, for the business share of use. They do not require a home office deduction. Mixed-use costs need a reasonable split.
Does using a home office raise my audit risk?
We cannot predict audits. A properly documented deduction is allowed when you meet the tests. The problems come when it is overstated or unsupported, so keeping good records matters.
What if I only work at home part of the year?
The space generally needs to be used regularly for the business during the time you claim. If your use began or ended partway through the year, the deduction may need to be prorated.
Can I claim a home office for a side business if I have a job?
Possibly. The side business is treated as its own activity, and the space used for it can qualify if it meets the tests. The job itself does not count for an employee.
