I built this because small business owners either have to use oversimplified calculators that don't handle real IRS rules, or pay for expensive accounting software just to get a depreciation schedule.

This handles: - All MACRS GDS property classes (3, 5, 7, 10, 15, 20, 27.5, 39 year) - Section 179 deductions ($1.25M limit for 2025) - Bonus depreciation (40% for 2025) - Luxury vehicle caps - Real property with mid-month conventions - PDF/CSV export

Free tier: 5 calculations/month. Pro ($14/mo): unlimited + saved schedules. Business ($29/mo): client management + Form 4562 worksheets for accountants.

Built with React, Supabase, Stripe, hosted on Replit. Happy to answer questions about the tax logic or tech stack.
