Pass your IFRS 16 audit the easy way: a finance team’s checklist

Since IFRS 16 brought most leases onto the balance sheet, lease audits have moved from a quick checkbox to a serious chunk of close-cycle work. Auditors want completeness, consistency, and a clear paper trail - across every contract, every modification, every entity.

Here’s what they actually look at, where teams usually trip, and how to walk into your next audit with everything ready.

What auditors are really checking

Strip away the jargon, and IFRS 16 audits come down to one question: does your reported lease data match reality?

To answer that, auditors typically dig into:

• Completeness - are all your leases on the books, including embedded ones?
• Classification - is each contract correctly identified as a lease (finance vs. operating where relevant)?
• Lease liabilities - are payments, discount rates, and present-value calculations accurate?
• ROU assets - initial measurement, depreciation, impairment
• Modifications and remeasurements - handled correctly when terms changed
• Disclosures - maturity analyses, weighted-average rates, reconciliations
• Reconciliation with the GL - do your lease records match what’s posted in the ledger?
• Audit trail - can you show who changed what, and when?

Miss any of these and you’re looking at adjustments, extended audit hours, or - in the worst case - material findings.

The seven steps of a clean lease audit

A structured approach beats firefighting every time. Here’s the playbook auditors follow - and the one your team should run internally before they arrive:

• Identify every lease. Pull from contracts, procurement, fixed asset registers, and expense accounts. Don’t forget embedded leases inside service agreements.
• Confirm classification. Lease or service? Operating or finance? Embedded components separated correctly?
• Validate the lease liability. Payments, discount rates, renewal/termination assumptions, present-value math.
• Check the ROU asset. Initial measurement, depreciation, impairment, treatment of incentives and direct costs.
• Review modifications and reassessments. Every contract change should trigger a remeasurement - and every remeasurement should leave a trace.
• Verify disclosures. Maturity analysis, interest expense, depreciation, short-term/low-value lease expense, total cash outflow.
• Check internal controls. Approval workflows, document management, consistent policies, full audit trail.

Run these seven yourself first. Whatever your auditor finds, you’ll already know about it.

Where finance teams lose ground

Most audit headaches don’t come from bad accounting. They come from fragmented systems and manual processes. The usual failure points:

• Lease data scattered across spreadsheets, drives, and inboxes
• Embedded leases that nobody flagged
• Discount rate assumptions undocumented or inconsistent
• Modifications handled “informally” - no remeasurement trail
• Disclosures rebuilt from scratch each year
• ERP and lease records out of sync
• No way to show who changed what

Each of these turns a 2-week audit into a 6-week audit. None of them are unsolvable.

How Onederful makes audits boring (in the best way)

Onederful is built natively into Microsoft Dynamics 365 Business Central - so lease data, calculations, journal entries, and disclosures all live in the same place as the rest of your finance data. No middleware. No re-keying. No reconciliation between systems.

Here’s what that means when audit season hits:

• Every lease, in one place. Contracts, amendments, payment schedules, and modification history - stored centrally and tied to each lease record.
• Calculations you can prove. Lease liabilities, ROU assets, depreciation, interest, remeasurements - all automated, all traceable.
• Disclosures, ready on demand. Maturity analyses, roll-forwards, weighted-average rates - generated in a few clicks, formatted to IFRS 16 (and ASC 842 and FRS 102) requirements.
• A full audit trail. Every change, every calculation, every journal entry - logged with timestamps and user IDs.
• GL alignment, built in. Journal entries post directly to your BC general ledger, so your lease records and your ledger always match.

When auditors ask “where did this number come from?” - you can show them in 30 seconds, not 30 minutes.

The bottom line

A clean IFRS 16 audit isn’t about working harder during audit season. It’s about having the right setup year-round - so when auditors arrive, the evidence is already there.
