Acorn9

Acorn 9 is a tax and accounting firm serving startups, founders, business owners, property investors, and cross-border businesses. It combines AI-powered agents, which manage routine work and track deadlines, with licensed CPAs who review decisions and prepare and sign tax returns. The firm aims to deliver clear answers quickly and provide support throughout the year, rather than focusing only on tax season.

Its services span company formation and annual maintenance, bookkeeping, federal and state tax filing, sales tax, and quarterly payroll tax filings. Acorn 9 also helps with entity selection, founder stock and 83(b) elections, QSBS planning, estimated payments, and owner compensation. For businesses with more complex needs, it handles multi-entity and cross-border matters, including international information returns, FBAR reporting, state registrations, and sales tax filings. Bookkeeping services include monthly close, reconciliations, and financial reports such as investor-ready profit and loss statements, balance sheets, and forecasts. Acorn 9 presents its work as an end-to-end service, from initial setup through ongoing compliance and annual filing.
