H&CO LLP is a Miami-based CPA firm that focuses on helping businesses with global tax compliance. When you look at hco.com, the first thing that stands out is the domain age: 24 years is exactly what you'd expect from an established professional services firm. That history, combined with a clean Google Web Risk report and no blacklist appearances, tells you this isn't a fly-by-night operation.
Most legitimate CPA firms have clear contact information, an About page, and social media links — H&CO has all of those. They also publish privacy and terms pages, which is appropriate for a business that may handle sensitive financial information. So on the surface, there's nothing to suggest hco.com is a scam.
However, the technical setup has a couple of rough edges. The site accepts old, insecure TLS versions, and there are quite a few external scripts and hidden page elements. For a CPA firm, that's more of a 'worth watching' detail than a dealbreaker — it could just be analytics and marketing tools that aren't perfectly configured. If you need to share sensitive data with H&CO, you might want to confirm they use a secure client portal rather than relying on the website's form alone.
Overall, hco.com checks the boxes for a real business with a long track record. It's not the cleanest site security-wise, but nothing here should stop you from reaching out to them through the contact info on their site.
