About the Firm
A small firm built around your paperwork, not the other way around.
AG Accountant LLC, based in Plainfield, IL 60586, prepares personal and business tax returns, forms new LLCs and corporations, keeps small-business books current, and covers the paperwork that tends to pile up around them — QuickBooks setup, payroll, notarization, and immigration form assistance — under one roof.
Clients are individuals filing a straightforward 1040, new entrepreneurs forming their first LLC, self-employed contractors juggling estimated payments, and small businesses that need their books and payroll handled every month, not just in April. The approach is the same for all of them: understand the full picture before touching a single form.
Documents can be reviewed remotely or in person, and every engagement starts with a plain-English conversation about what you actually owe, what you're eligible for, and what's due when.
