Frequently Asked Questions
Yes, renters can claim the home office deduction. Instead of mortgage interest and property taxes, you can deduct a portion of your rent. Use the same business percentage calculation. You can also deduct renter's insurance, utilities, and repairs. However, you cannot depreciate rental property you don't own.
If you use the actual expense method and claim depreciation, you must recapture depreciation when you sell. This means paying tax on depreciation claimed at a maximum 25% rate. The home office portion may also affect your $250,000/$500,000 capital gains exclusion. The simplified method generally avoids these complications.
Generally no, since 2018. The Tax Cuts and Jobs Act suspended unreimbursed employee expenses, including home office, through 2025. This may change in 2026. However, self-employed individuals, independent contractors, and business owners can still claim. If you're both an employee and have a side business, you can claim for the business portion.
Yes, but with limitations. The home office deduction cannot create or increase a business loss. You can carry forward unused deductions to future profitable years. This rule prevents using home office to generate artificial losses. The IRS also looks for profit motive—consistent losses may trigger hobby loss rules.
If both use the space for separate businesses, you can each claim a portion based on your exclusive use time/area. Document usage schedules. If you have a joint business, claim once on that business return. Never double-deduct the same space. Proper documentation of separate business use is crucial for shared spaces.
Claiming non-exclusive space. The #1 audit trigger is claiming a space that's also used personally. A home office must be used exclusively and regularly for business. A guest bedroom/office combination doesn't qualify. Other common mistakes: poor documentation, unrealistic square footage, and not understanding depreciation recapture.
