Compare the Simplified Method vs. Actual Expenses to maximize your tax savings.
Home Business Percentage:0%
Simplified Method Deduction ($5/sqft):$0
Actual Expenses Deduction:$0
How the Home Office Deduction Works
If you use a portion of your home exclusively and regularly for business, the IRS allows you to deduct expenses related to that space. This applies whether you own or rent your home, and whether you live in a house, apartment, or condo.
There are two primary ways to calculate this deduction:
Simplified Method: You claim a flat rate of $5 per square foot of home office space, up to a maximum of 300 square feet ($1,500 total). This method is significantly easier for record-keeping.
Actual Expenses Method: You calculate the percentage of your home used for business and apply that percentage to home-related costs like mortgage interest, rent, utilities, and insurance.
Realistic Example:
Sarah uses a 200 sq. ft. room in her 2,000 sq. ft. home as her primary office (10%). Her annual expenses (rent, utilities, insurance) total $30,000.
– Simplified Method: 200 sq. ft. × $5 = $1,000 deduction.
– Actual Method: 10% of $30,000 = $3,000 deduction.
In this case, the Actual Method saves Sarah significantly more on her taxes.
Eligibility Requirements
To qualify for the deduction, your home office must meet two main criteria:
Regular and Exclusive Use: You must use a specific area of your home only for your trade or business. If you use your dining table for work during the day and dinner at night, that area does not qualify.
Principal Place of Business: Your home office must be the primary location where you conduct business or meet with clients/patients.
Which Method Should You Choose?
If your home office is small and your home expenses are low, the Simplified Method is usually better because it requires less paperwork. However, for those living in high-cost-of-living areas with large mortgages or high rent, the Actual Expenses method often provides a much larger tax break.
