Can I write off my home office?
TL;DR
Yes, you can write off your home office if it is used exclusively and regularly for your business.
Detailed Answer
Where to Put It on the Tax Form
You report this deduction on Form 8829, Expenses for Business Use of Your Home, which you submit with your Schedule C, Profit or Loss From Business.
Real World Example
For instance, if you are a freelance graphic designer and use a room in your home exclusively and regularly for your business, you can write off a portion of your home expenses, such as mortgage interest, property taxes, and utilities. The amount would be based on the percentage of your home that the office occupies.
Calculation Required
A calculation is required for this deduction.
To calculate the deduction, you need to determine the percentage of your home used for business. This is typically calculated by dividing the square footage of the office by the total square footage of the home. This percentage is then applied to eligible home expenses to determine the deductible amount.
Audit Risk & Documentation Tips
This deduction can increase your audit risk, so it's important to keep detailed records. Document the square footage of your office and your entire home, and keep receipts for all home expenses. If you're an employee, also keep records showing that you use the home office for the convenience of your employer.
