Grove Hopper is a research tool with reminders and document preparation. We prepare your appeal documents and you review, sign, and file them yourself. We never file or represent anyone, and we are not attorneys, accountants, or a tax firm. Dates and rules here come from the official pages linked above and can change; check your notice and your county's site before you file.
