ERISA 401(k) and 403(b) plan audits

The mandatory audit, finally made painless.

Ledgerline is a specialist audit firm for 401(k) and 403(b) plans, launching for the upcoming season. We pull payroll data straight from the source and reconcile it against your recordkeeper’s records ourselves, so you provide far less, and the audit is built to move in weeks, not months.

The problem today

Right now, the annual 401(k) audit is a four-month chore.

Mid-market plan sponsors are required to get one every year, and most dread it. The work is slow, the back-and-forth is endless, and it all lands at once.

01

Slow by default

Roughly four months of requests, reviews, and follow-ups before anything is signed.

02

The endless PBC list

A document request list that never seems to end, with the same items chased again and again.

03

A seasonal scramble

Everything collides into one deadline, so every year ends in a last-minute crunch.

04

A low-priority chore

Generalist firms treat plan audits as a side task, so the sponsor feels like an afterthought.

Our approach

We do the heavy lifting, so you barely feel the audit.

We pull and reconcile plan data directly from recordkeeper and payroll systems, so you'll provide a fraction of what a generalist asks for, and the audit moves at the pace of software, not paperwork.

We pull your payroll data, not request it

Connect your payroll provider once and your census and payroll register come straight from the source. Your recordkeeper's year-end package goes on the same checklist, so you're never digging up files that already live somewhere.

Everyone uploads their piece, no one's asked twice

HR, your TPA, and your finance lead each get a link to only what's theirs, and they upload directly, on their own time. Nothing gets requested twice, and no one's stuck relaying documents they can't answer for.

We tie it out, so you don't assemble anything

We reconcile your contributions across payroll, the trust, and the recordkeeper ourselves. You hand over source data, not assembled schedules. The tie-out is our job, not yours.

Why a specialist

Purpose-built for the 401(k) and 403(b) plan audit.

ERISA 401(k) and 403(b) plan audits are among the most standardized audits there are. By focusing on them exclusively, we're building a firm that is faster, more accurate, and more predictable than generalists.

One audit, deeply understood

Every part of our process is shaped around a single, repeatable workflow, not a generic audit template.

Every record, not a sample

Our testing runs on the whole population instead of a sample: every participant, pay period, distribution, loan, fee and journal entry in your plan's records, on the same timeline.

Predictable by design

A specialist process means fewer surprises, clearer timelines, and a year that doesn't end in a scramble.

For TPAs and recordkeepers

Less work for your team. Not less audit.

We work alongside TPAs and recordkeepers. We make the audit easier on everyone who supplies documents, without making it any lighter: testing covers the plan’s whole population, not a sample.

How we work with TPAs and recordkeepers

A referral you can stand behind

A thorough audit that runs smoothly reflects well on whoever recommended it.

We ask for what you hold, once

Your team sees only its own items, and we work from the data you already maintain.

We'll never compete with you

We do one thing: the plan audit. Your administration and recordkeeping relationships stay yours.

Who's behind it

Experienced, licensed auditors, with the engineering to make the audit painless.

The people building Ledgerline pair real Big-Four assurance depth with the engineering background to build a faster audit process, so you get serious audit credibility and a modern, low-hassle experience, as one team.

As we approach launch, we're assembling a founding team of experienced ERISA and employee-benefit-plan auditors to stand behind every engagement.

Before you ask

Questions a careful sponsor asks.

We're pre-launch and building deliberately. Here's how we're thinking about the things that matter most to a CFO.

Does my plan even need an audit?

Generally, plans with 100 or more participants with balances (with some nuance under the 80-to-120 rule) are required to file audited financial statements with Form 5500. We'll help you confirm where your plan stands.

How will you handle our data?

We're building on a security-first foundation, with encryption in transit and at rest and least-privilege access to payroll connections. We'll share our full security posture as we approach launch.

Are you independent of my other providers?

Yes. We do one thing, the plan audit, and maintain independence from your recordkeeper, TPA, and advisors so the audit stays objective.

Our vision

Building the specialist firm for mandated assurance, starting with 401(k).

Tens of thousands of plans are required to be audited each year by law, and the experience has barely changed in decades. The most standardized, most mandatory audit is exactly where a modern, specialist firm should begin.

Founded by Tunde Adewole and Junhyuk Lee, Ledgerline is building that firm now, and launching for the upcoming audit season.
