Arc & Ledger Tax Tools is a set of free, read-only tax calculators and explainers built by an Enrolled Agent enrolled to practice before the IRS. Decode an IRS notice, check FBAR/FATCA obligations, compare LLC vs S-Corp, estimate quarterly taxes and IRS penalties, check ITIN eligibility, compare US formation states, and more. Every answer is general information (not tax advice) and can hand you off to a human Enrolled Agent if you want personal help. Especially useful for US small businesses, international founders, and anyone who just received an IRS letter. No account or login required.
