The important part, without fine print: what Sumalis is, what it is not, and what happens with your data.
Sumalis is an educational project of free tools about U.S. finances and business structures, created by Onell Lanfranco — Certified Public Accountant (Argentina), IRS Tax Preparer (PTIN) and Florida Notary Public — as part of the onell.us / emprendenus.com ecosystem.
The calculators and content on this site are general educational estimates. They do not constitute tax, legal, accounting or immigration advice, and using them does not create a professional-client relationship. Tax rules change: always verify current-year figures and review your case with a professional before making decisions.
We take care to keep tables (brackets, rates, caps) current and cite sources where relevant, but we do not guarantee the absence of errors or applicability to your particular situation. You use this site at your own responsibility.
The calculators run entirely in your browser: the numbers you enter are not sent to any server or stored. The site uses aggregate traffic metrics to understand which tools are used; we do not sell or share personal data. If you email us, we use your address only to reply.
The site links to onell.us, emprendenus.com and occasionally to official sources (IRS, FinCEN) or external providers. Each has its own terms and policies.
Questions about these terms: [email protected].
