Tanner LLC
helper active confidence: Medium status: Draft updated 2026-07-14
Summary
Tanner LLC is a Salt Lake City public accounting firm founded in 1940, with a second office in Lehi. For a founder, the useful framing is: the established local choice when you need real audit, tax, and transaction-grade accounting rather than just bookkeeping.
Impact
Accounting becomes a gating function at predictable moments: a venture round where the investor wants reviewed or audited financials, an acquisition where the buyer runs financial due diligence, an SEC-reporting obligation, or a tax structure that quietly costs the company money. A founder who waits until those moments to find a credible firm is negotiating from a weak position.
A firm that does audits, M&A due diligence, and SEC-reporting consultation can give a Utah company financials that survive outside scrutiny — which is exactly what raises and exits require.
Who They Help
From the firm's public service descriptions, Tanner LLC can help with:
- Assurance / audit — public and private company audits, employee-benefit-plan audits, reviews, and compilations.
- Transaction support — M&A due diligence and SEC reporting consultation.
- Tax — corporate, partnership, and individual tax filings and tax strategy.
- Advisory and technology — strategic planning plus technology and data-security consulting. Tanner LLC Official Website
The firm publicly emphasizes that its independence lets it give objective, agile service to "Silicon Slopes" entrepreneurs.
Best-Fit Founders
The strongest fit is a Utah company at the point where financial credibility matters to an outside party — a startup approaching a priced round that needs reviewed/audited financials, a company preparing for or going through an acquisition, a business with benefit-plan or SEC obligations, or a growth company that wants a serious local tax and advisory relationship.
It is more firm than a pre-revenue solo founder needs for basic books; that founder may start with bookkeeping plus Utah SBDC financial guidance and bring in Tanner when an audit, diligence, or complex tax question arrives.
Cost / Engagement Model
Tanner is a full-service CPA firm; audit, tax, and advisory engagements are scoped and priced per engagement, not published as packages. Founders should ask whether the immediate need is an audit, a review, a tax engagement, or advisory work, and get a scoped estimate — the cost and timeline differ sharply between, say, a compilation and a full audit. Confirm capacity around busy season.
Proof Points
- Public firm materials describe audit, due-diligence, tax, SEC-reporting-consultation, and advisory services, and membership in Allinial Global (an association of independent firms with international reach). Tanner LLC Official Website
- Utah Business press coverage describes Tanner as one of the largest locally owned public accounting firms in Utah, founded in 1940 — a date-sensitive, press-reported claim.
Good Matches
A good match is a Utah venture that has reached the stage where audited financials, transaction diligence, or sophisticated tax planning unlock the next step — a raise, an acquisition, or compliant growth. It pairs naturally with corporate counsel (e.g., Kirton McConkie) on a financing or M&A deal, where lawyers and accountants split the work.
Cautions
This page describes public capabilities; it does not claim Tanner has agreed to take on any specific client or quoted a price. Audit independence rules can limit which other services a firm provides to the same client — discuss this if you want both audit and advisory work. Verify scope, fees, and timing (especially around tax/audit busy season) before relying on the firm for a deadline.
Evidence
Open Questions
- For an early-stage company, what is the realistic cost difference between a compilation, a review, and a full audit?
- Which engagements does Tanner take on for pre-revenue startups versus later-stage companies?
- How does it compare with a national firm like Eide Bailly for a Utah company weighing local independence against national-network breadth?
