Business Tax Services

Business Tax Services

Whatever your entity, your business tax handled by one senior team. Federal, state, and the planning in between.

What you get

The engagement, in a nutshell.

Every Alpine Mar business tax services engagement is built on the same four commitments.

  • 01

    Partner Involvement

    A CPA on every engagement. No junior handoff once you sign.

  • 02

    Fixed-fee, scoped

    Scope and price agreed before we start. No hourly meter or surprise invoices.

  • 03

    Year-round attention

    We work the calendar, not just the deadline. Quarterly check-ins by default.

  • 04

    Modern finance stack

    Cloud books, AI, automation, and secure portals. Work moves faster without losing rigor.

How we work

From first call to closed loop.

Four predictable steps. No surprise scope creep, no junior handoffs, no hourly meter ticking on routine questions.

  1. Step 01

    Intro call

    An introductory call including the partner who'd run your engagement. We cover scope, timing, and fit.

  2. Step 02

    Discovery

    We look at your books, prior filings, and stack. You get a scoping memo and a flat fee.

  3. Step 03

    Engagement

    Work is delivered by a senior team. You see drafts, not silence, with weekly status by default.

  4. Step 04

    Wrap-up

    Deliverables ship with a written summary. You keep working with the same team next round.

5 star Google review
We’ve had a great experience working with Alpine Mar for our accounting and tax needs. They’ve been a strong partner for us — responsive, knowledgeable, and easy to work with, even as our business has grown more complex. I work closely with Pablo and Emily, and both have been fantastic. They’re proactive, detail-oriented, and always willing to walk through questions or help think through strategy instead of just checking boxes. It’s clear they genuinely care about doing things right and helping us stay organized and informed. Highly recommend Alpine Mar if you’re looking for a team that feels more like a partner than just an accounting firm.

Common questions

Before you book the call.

Quick answers to the things most people ask before signing on for business tax services.

How quickly can we start?

We schedule an intro call within a few business days and can begin scoping the same week.

How are fees structured?

Business Tax Services is quoted as a fixed fee with a clearly scoped deliverable, after the intro call. We don't bill by the hour for known scopes. Ongoing work (like monthly close or fractional CFO) is a flat monthly retainer.

Will I work with the same person, or get passed around?

Every engagement is partner-led. The senior CPA you meet on the intro is the one running your file. Day-to-day support comes from a senior associate, with partner sign-off on every deliverable.

Are you taking new clients?

Yes. We're actively onboarding new clients year-round, and we pace intake so every partner can hold the service standard the firm is known for.
