"I'd love to take the home office deduction, but my house is just too small."
Actually, it might not be. Many people picture a home office as an entire spare bedroom with a desk, bookshelves, and a computer. The IRS doesn't require that.
In fact, your qualifying office space could be surprisingly small.
The IRS doesn't focus on how large your office is. It focuses on how you use it.
If you have an area in your home that is used exclusively for business and it qualifies as your principal place of business, you may qualify for the home office deduction. That exclusive-use rule is important.
If the same space is used for personal activities, you may lose the deduction.
The article I recently read discussed using nothing more than the footprint of a floor-standing file cabinet, roughly three square feet. The idea is simple.
Use that cabinet only for business records and business supplies. When you need to work, pull up a table or desk nearby to complete your administrative work. When you're finished, the table can be moved, but the business area remains dedicated to your business.
It's certainly not what most people picture when they think of a home office.
Many people assume the biggest benefit of a home office deduction is writing off part of their utilities, mortgage interest, rent, or property taxes. Those deductions can certainly help. But for many business owners, an even bigger benefit is the mileage deduction.
When your home qualifies as your principal place of business, trips from your home office to another business location may become business miles instead of commuting miles. Under the rules discussed in the article, that change can create a significant deduction over the course of a year.
For someone who drives to clients or another office regularly, those miles can add up quickly.
What Makes Your Home the Principal Place of Business?
This is where people often get confused. Simply answering a few emails at your kitchen table doesn't qualify.
Generally, your home office should be the place where you perform your administrative or management activities, such as:
- Scheduling appointments
- Keeping your books
- Paying bills
- Ordering supplies
- Preparing reports
- Handling business records
If those tasks are performed in your home office and you don't have another fixed location where you perform substantial administrative work, your home office may qualify as your principal place of business.
Don't Push the Rules
Like many tax strategies, this one depends on documentation and following the rules. Trying to stretch the definition of "exclusive use" or claiming personal space as business space can create problems if you're ever audited.
The goal isn't to claim the largest deduction possible. The goal is to claim the deduction you're legally entitled to.
Don't assume your home is too small for a home office deduction. Sometimes the obstacle isn't the size of the house. It's simply not knowing the rules.
A surprisingly small space could open the door to deductions you didn't realize were available.
