Our Credentials

Backed by an
IRS Enrolled Agent

Not every tax preparer can speak for you when the IRS has questions. An Enrolled Agent can — in any state, on any tax matter, without limitation.

  • Represent you in IRS examinations, appeals, and collections
  • Licensed federally — not limited to one state's clients
  • Required to complete continuing education every year
  • Held to the ethics standards of IRS Circular 230
What is an Enrolled Agent?
An enrolled agent (EA) is a federally licensed tax practitioner with unlimited rights to represent taxpayers before the Internal Revenue Service. They hold the highest credential awarded by the IRS, allowing them to handle any tax matter, for any client, in any U.S. state.

Our Process

How we work together

Five steps from first conversation to year-round support — with everything after step one happening inside your secure portal.

  1. Connect

    A conversation about your business, then a short questionnaire so we understand the details.

  2. Portal invite

    We set up your secure account and walk you through two-factor sign-in.

  3. Share documents

    Upload statements and records to the portal — never to email — and message us there with questions.

  4. We prepare

    Reconciled, reviewed, and explained in plain language before anything is filed.

  5. Ongoing support

    Reminders ahead of every deadline, notes when tax law changes affect you, and answers year-round.

Who We Serve

Accounting built for your kind of business

Most of our clients run businesses with fewer than twenty people — sole proprietors, LLCs, S-Corps and C-Corps alike. Here's where we spend most of our time.

Don't see yours? We've worked across a lot of industries — ask us.

Our Story

Numbers handled with care,
people treated like neighbors

Copper & Vine started with a straightforward idea: small business owners deserve an accountant who picks up the phone, explains the why, and treats a set of books like it belongs to a person rather than an account number.

We're based in Missoula, Montana, and we can work with clients in any state. The Montana part isn't a limitation — it's just where we are, and it shapes how we work: directly, plainly, and without the runaround.
