Starting an architecture firm comes with significant upfront costs, but the IRS allows you to deduct many of them. This guide covers the complete list of tax write-offs for new architecture firms, with realistic 2026 figures and practical steps to claim them. From software subscriptions to professional fees, you can reduce your taxable income and keep more of your revenue.

Example: If your home office is 200 square feet and your home is 2,000 square feet, you can deduct 10% of your rent or mortgage interest, utilities, and internet.
