Deductible Amount
$2.40K
Business Use

Your 200 sq ft office represents 10.0% of your 2000 sq ft home, making $2,400 of your $24,000 annual home expenses deductible.
The IRS offers two methods for calculating your home office deduction. The Regular Method uses your actual home expenses multiplied by the business use percentage. The Simplified Method allows $5 per square foot, up to a maximum of 300 sq ft ($1,500).
Your deduction is limited to your gross business income. To qualify, your home office must be used regularly and exclusively for business purposes.

Regular Method = Annual Home Expenses × (Office SF ÷ Total Home SF); Simplified Method = min(Office SF, 300) × $5
The Regular Method calculates deduction based on your business use percentage of actual home expenses. The Simplified Method provides a flat $5 per square foot up to a 300 square foot maximum.
The IRS offers two methods for calculating home office deductions, and the best choice depends on your specific situation. The Regular Method calculates a percentage of actual home expenses based on office size, while the Simplified Method offers a flat $5 per square foot.
The Simplified Method saves time and record-keeping effort but is capped at $1,500 (300 sq ft × $5). For home offices with high expenses or larger spaces, the Regular Method often provides a significantly larger deduction.
You can switch between methods each tax year, so it's worth calculating both annually to maximize your deduction. The Regular Method also allows depreciation deductions that the Simplified Method does not.

Direct expenses (used only for office) are fully deductible. Indirect expenses (benefiting entire home) are deductible based on business use percentage. This includes mortgage interest or rent, utilities, insurance, repairs, maintenance, depreciation, and association fees. Some expenses like lawn care typically don't qualify.
Yes, you can switch methods from year to year. However, if you use the Simplified Method, you cannot deduct depreciation that year, and you cannot carry over any depreciation to future years for those years you use the Simplified Method.
The space must be used regularly and exclusively for business. A desk in a living room that's also used for personal activities typically doesn't qualify. However, a dedicated room or clearly defined space used only for work meets the requirement. Daycare facilities have an exception to the exclusive use rule.
