• Calculate home office deduction (simplified method: $5 per square foot, up to 300 sq ft; or actual expense method)
• Review equipment purchases (computers, cameras, software) for Section 179 deduction (up to $1,220,000 in 2026) or depreciation
• Compile business travel receipts (mileage, flights, hotels) and apply the 2026 standard mileage rate of $0.67 per mile
