Hey Product Hunt 👋 Yesterday was Tax Day. If you're a crypto holder in the US, you might have spent the last few weeks wrestling with a Form 8949 that just wouldn't balance. Or realizing at the last minute that your 1099-DA doesn't match what your tool says. Or filing an extension because the math simply doesn't work. You're not alone. I was in that situation a year ago. I'm Franklin, a new American immigrant (EB1A extraordinary ability) and the solo founder of dTax. I bought my first Bitcoin back in 2012. Fourteen years later, in 2026, I filed my first US tax return — and every existing crypto tax tool failed me. My story wasn't simple: early Bitcoin holder, multi-chain DeFi positions going back years, cross-border income, a brand-new US tax residency, and wallet trails across exchanges that don't even exist anymore. I tried CoinTracker. I tried Koinly. I hired two senior CPAs, one of them with a serious crypto reputation. Nobody could give me a correct return. So I built dTax. Not because I wanted to start another SaaS — because I had no other choice. I taxed my own money to get the engine right, then realized millions of people have the same problem: early holders, DeFi natives, new immigrants, cross-border earners, CPAs serving complicated clients. What makes dTax different • AI-native, not a CSV importer: dTax's AI assistant reads your real transaction data and cites actual IRS rulings — no hallucinations. • Real-time regulation tracking: We monitor SEC, IRS, HMRC, ATO, JFSA, and more, 365 days a year. Your report always reflects the latest law, not a 2023 training cutoff. Rev. Proc. 2024-28 per-wallet basis is implemented and on by default. • 22 chains, 26 exchanges, 13 cost-basis methods: Including UK Section 104 pooling, Japan 総平均法, Spain FIFO, India VDA. The hard cases. • Open source (AGPL-3.0): The first open-core crypto tax tool. You can self-host, audit the code, and own your data forever. github.com/dTaxLab/dtax • Bootstrapped: No investors. No VC term sheets. Just my own savings and my own Bitcoin. When you pay dTax, you're paying a founder — not a VC return. Pricing that respects you • Free forever: 50 transactions/day, 5 AI chats/day — enough for most beginners. • Pro: $49/year or $199 lifetime (yes, literally lifetime — I'm committing to this). • CPA: $499/year for professionals managing client portfolios. What I'd love from you today 1 Try it at getdtax.com — import a wallet, ask the AI a question, break something. 2 Tell me what's wrong — I'll read every comment today and respond personally. 3 If Tax Day was ugly for you, I genuinely want to know what your tool failed at. That's how dTax gets better. I'm here all day. Ask me anything about crypto tax, being a new immigrant founder, bootstrapping without VC, or why I think the big players are about to lose this category. Thanks for having me. 🙏 — Franklin, founder of dTax
