The $1,500 simplified cap leaves money on the table for most renters. Prove it.
The simplified home office method ($5 per square foot, 300 sq ft max) exists to save recordkeeping, not to save you the most tax — for anyone paying real rent or mortgage in a high-cost area, the actual-expense method usually wins by four figures. This calculator runs both against your numbers, shows the winner and the gap, and converts the deduction into actual cash saved at your tax rates.
Freelancers and gig workers use it at tax time — or better, in January when the year can still be planned. The simplified method's $1,500 cap quietly loses to actual expenses for most renters, and seeing the gap in dollars is what makes the recordkeeping worth it.
Simplified method: $5 per square foot up to 300 sq ft, capped at $1,500. Actual method: your business percentage of real housing costs — a 150 sq ft office in a 2,000 sq ft home (7.5%) with $28,800 of rent and utilities deducts $2,160, beating simplified by $660. At the 22% bracket plus ~14.1% self-employment tax, $2,160 of deduction returns about $780 in cash.
No. The miscellaneous deduction for employee business expenses was suspended by the TCJA in 2018, and the One Big Beautiful Bill Act (2025) made that suspension permanent. The home office deduction is now self-employed only — sole proprietors, freelancers, gig workers, and single-member LLCs reporting on Schedule C.
The exclusive-use test: the space must be used regularly and only for business. A desk in the guest bedroom that hosts visitors twice a year fails; a kitchen table fails; a dedicated room or a clearly partitioned area passes. Other limits: the deduction cannot exceed business income (it cannot create a loss — actual-method excess carries forward), and homeowners using the actual method face depreciation recapture when they sell, which is the hidden cost of the bigger deduction.
