Server instructions

Educational US tax reference tools from Arc & Ledger Accounting. Arc & Ledger is not a CPA firm; its practitioners are not licensed by the State of California as certified public accountants, and the services it offers do not require a California state license. Use these tools to explain an IRS notice or tax document, screen general filing and reporting rules, and calculate clearly labeled estimates. The tools do not prepare or file a return, transmit data to a tax authority, create an engagement, sell a service, or replace review by a qualified tax professional. Do not ask for Social Security numbers, tax account numbers, bank details, passwords, or documents. Treat every result as general information and verify it against the cited official authority before the user acts.
