For more detailed information regarding tax deductions for your home office, please see IRS Publication 587, Business Use of Your Home.
Here are some of the most frequently asked questions:
1. I manage rentals from my home, but TurboTax does not let me deduct my home office. Why not?
Passive income does not qualify for the home office deduction, and the IRS considers rental property income as passive.
To qualify for a home office deduction you would need to have a small business (Schedule C), a farm/ranch (Schedule F), or be an employee who is required by the employer to maintain a office in their home.
2. I entered the info for the home office deduction but my taxes stayed the same. How come?
Most of the expenses associated with the home office deduction cannot create or increase a loss for your business.
However, deductible mortgage interest, real estate taxes, and casualty losses can create or increase a business loss, while other expenses including rent, utilities, maintenance, and insurance cannot.
These disallowed losses can be carried over to the following year until they can be used.
3. If I have two businesses, can I take the home office deduction twice?
Yes, if you meet all of the requirements for both businesses. If you have a separate space for each business then you will just do the home office process twice.
If you have two businesses that share the same office space, then you will need to split the space and expenses between the two companies.
4. I do most of my work at the homes and businesses of my clients. Can I still take a deduction?
Probably.
Even though you perform work at clients' homes (as a plumber or IT technician, for example), if you perform administrative tasks from your home and meet the other home-office requirements, then you would likely qualify.
5. Can I claim the home office deduction for my investing activities?
Probably not.
If you are classified as a trader and meet all of the requirements for the home office deduction, then probably yes.
If you are managing your investments rather than working as a trader, then this would not be classified as a business, and you would not meet the requirements of the home office deduction.
6. As a teacher, can I deduct a home office since I work there at night and weekends?
Probably not.
If you are a classroom teacher at a school with a building then you have a normal place of business that is not your home.
However, if you taught for an internet based school and had no other place of business, then you would be able to take a deduction if you meet the other requirements.
7. I only worked part of the year from home. What can I deduct?
If you meet the office in home requirements for only part of the year, you can still take a portion of the expenses as a deduction.
For example, if you only worked half of the year from home, then you would take half of what you would take if you had do this for the entire year.
8. Do I have to depreciate my home?
No, but you might as well.
If you take the home office deduction, depreciation is allowed.
So, even if you don't use it, you will have been deemed to have taken it by the IRS. This comes into play when you sell your home and need to recapture the depreciation if you have a gain on the sale.
9. Can a percentage of my office be used in the IRS definition of exclusively?
You can use whatever portion of your home that meets the IRS exclusive requirement, even if the area is a small portion of a larger area.
