If you rent space to run your business, an office, a studio, a workshop, a storefront, or a coworking desk or membership, the rent is a fully deductible business expense on Line 20b. A day pass or monthly coworking fee counts the same way.
Renting equipment for your business, tools, a camera, a vehicle, or machinery, is also deductible, on Line 20a. If you lease a car for business, the business-use portion of the lease is deductible under the vehicle rules.
Your personal home rent is not a business expense by itself. The way to deduct part of it is the home office deduction: if a space in your home is used regularly and exclusively for business, the regular method lets you deduct the business-use percentage of your rent, utilities, and insurance. The simplified method instead gives a flat $5 per square foot up to 300 square feet.
Keep your lease, invoices, or coworking receipts. If you use the home office route, keep the rent records and the square-footage calculation that supports your business-use percentage.
