Show HN: ProfiTree – Find Hidden Tax Savings in Your Investment Portfolio
I’ve been building ProfiTree, a tool to help investors—especially those managing their own portfolios—spot tax savings that are easy to miss.
If you're an active trader, it flags disallowed losses from wash sales that can quietly wipe out your tax benefits. If you're a long-term/passive investor, it surfaces opportunities to harvest losses you might not realize are there.
I started this after realizing I had personally missed out on tax savings just because I didn’t have visibility. ProfiTree connects securely to your brokerage (via SnapTrade – read-only access), analyzes your past trades, and highlights where you could have saved—and how to avoid missing out in the future. No transactions are ever made, it’s just insights and guidance.
It's still in early phase, but I’d love your feedback on:
Does this feel useful for the way you invest?
1. Is the value prop clear?
2. What would make this a “must-use” during tax season?
Appreciate you giving it a look https://www.profitree-tax.com
