OFFICIAL MERCURY BANK PARTNER — SEPTEMBER 2026
Form5472.online is now the official Form 5472 tax filing partner of Mercury Bank — one of the most widely used banking platforms among foreign founders and non-U.S. residents owning U.S. LLCs. Verify at mercury.com/perks/form5472
Mercury Bank serves a very specific client: the international entrepreneur who has opened a U.S. LLC to operate a business, receive payments, or build a company from outside the United States. That client has a U.S. bank account. They almost certainly have a Form 5472 filing obligation. And until now, finding the right service to handle that filing meant doing their own research in a market full of software tools, anonymous platforms, and general CPA firms that have never seen a foreign-owned disregarded entity.
When Mercury selects a partner for its perks program, it does not choose randomly. The Mercury perks program exists to connect its clients with tools and services that have been evaluated and found to be a genuine fit. Being listed as a Mercury partner is a statement about what Mercury believes its clients should use.
We think it is worth explaining what that selection means — and why it happened.
What Mercury Is
Mercury is a financial technology company that offers business banking services to startups, small businesses, and international founders. It is particularly well known in the foreign founder community — the global entrepreneurs, SaaS builders, e-commerce sellers, and digital nomads who form U.S. LLCs to access U.S. banking infrastructure and payment systems.
Mercury's client base is precisely the population that Form5472.online was built to serve. Foreign nationals owning U.S. single-member LLCs. Non-U.S. residents with reportable transactions between themselves and their companies. Founders who are expert in their own field but have never encountered Form 5472 before.
What a Mercury Partnership Means
Mercury's perks program connects its clients with services across legal, accounting, software, and operations. Being selected as a partner in this program means Mercury has decided that Form5472.online is the right service to refer its clients to for Form 5472 compliance.
That is not a small thing. Mercury's clients trust Mercury's recommendations. When a Mercury client opens the perks page and sees Form5472.online listed as the Form 5472 partner, they are receiving a referral from their bank — the institution that holds their business account and knows their company exists.
A bank that refers its clients to a tax filing service is putting its own reputation behind that referral. Mercury chose Form5472.online. That choice reflects what Mercury found when it evaluated the options available to its clients.
What We Believe Mercury Found
We cannot speak for Mercury's internal evaluation process. What we can say is what makes Form5472.online different from the other Form 5472 services in the market — and what any serious evaluation of this space would find.
A named, independently verifiable licensed CPA
Every Form 5472 return prepared through Form5472.online is prepared, reviewed, and signed by Arik Rozen, CPA, MBA — Virginia Board of Accountancy License #025991. That credential is verifiable before you pay, through a government database that has no connection to Form5472.online. Most other dedicated Form 5472 services in this market do not publish a named CPA, do not provide a license number, and cannot be independently verified.
Twenty-two years of operating history
Tax USA Inc., the entity behind Form5472.online, has been an IRS Authorized e-File Provider since 2004. That is verifiable through the IRS e-File Provider database — search Tax USA Inc., zip 11230. A service launched in 2025 or 2026 has not yet completed a single Form 5472 filing season. Form5472.online has completed more than twenty of them.
Independent customer evidence
Form5472.online has 50 independently verified customer reviews on Trustpilot, rated 4.8 out of 5. Those reviews are on a platform Form5472.online does not control, from customers who paid for the service and filed a return. That is a different category of evidence from on-site testimonials or review counts published on a provider's own website.
A service built for exactly this client
Form5472.online was built specifically for foreign-owned U.S. entities. Not adapted from a domestic tax service. Not a side offering from a general CPA firm. The registered agent fee issue, the dormant LLC trap, the pro forma Form 1120 requirement, the IRS fax submission procedure — these are the foundation of the service, not edge cases handled reluctantly.
What This Means for Mercury Clients
If you are a Mercury client with a foreign-owned U.S. LLC, you likely have a Form 5472 filing obligation every year your LLC exists. The registered agent fee your LLC pays — or that you pay personally on behalf of your LLC — is almost certainly a reportable transaction. The IRS penalty for a missing or substantially incomplete Form 5472 is $25,000 per year, automatic, with no grace period.
The Mercury partnership means you now have a direct path from your bank account to CPA-prepared Form 5472 compliance — with a service your bank has chosen to stand behind.
