Choosing the Regular Method
Someone with a larger home office and higher expenses might benefit from sticking with the regular method of determining the home office deduction. With the regular method, there is no limit on the amount of office space used for business. You determine the deduction by figuring out the percentage of your home used for business.
Claiming your home office deduction using the regular method doesn’t stop at the home itself. You can use your business use calculation to determine how much of the following can be deducted for business use as well:
- Mortgage (or rent) payment
- Utility costs
- Homeowners (or renters) insurance premiums
For example, if your home is 2,500 square feet and your home office is 400 square feet, you use 16% of your home for business. You are allowed to add up 16% of your housing payments, utility costs and insurance premiums to use as your home office deduction.
You can divide up your home-related deductions between Schedule A and a business Schedule C or Schedule F, whichever you use. It’s also possible to deduct a portion of the home’s depreciation when you use the regular method. Although if your home has appreciated by the time you sell, some of the deduction will be recaptured, meaning the IRS will view the gain as ordinary income.
If your deduction amount is larger than your gross income from the business use of your home, it’s possible to carry the excess amount to the next year. So if your deduction comes to $3,500, but your gross income from the use of your home amounts to $3,000, you can’t claim that “extra” $500, but you can carry it over to next year. This is a feature that isn’t possible with the simplified method.
Using the regular method can result in a larger tax deduction depending on your situation, but it also requires more attentive record keeping and calculation.
