IFRS 18 is Coming January 2027 — Transfer Pricing Data Must Start Now

Read Time: 6 minutes

The Timing Trap

IFRS 18 becomes mandatory on January 1, 2027 — six months away. Most UAE finance teams know this intellectually. Nearly none are prepared operationally.

Here’s the trap: IFRS 18 requires retrospective restatement of your 2026 comparative data. That means your 2026 financial statements, published in early 2027, must already be captured under the new standard. If you wait until December 2026 to figure out your IFRS 18 chart of accounts, you’ve already failed.

For transfer pricing teams, the stakes are even higher.

What IFRS 18 Actually Changes (And What It Doesn’t)

Let’s be precise, because the fear around IFRS 18 is often overblown.

IFRS 18 does NOT change:

• Recognition and measurement rules (those stay in IFRS 15, 16, 9, etc.)
• Your taxable income calculation under UAE Corporate Tax Law
• Transfer pricing documentation requirements

IFRS 18 DOES change:

• How you present and categorize items in the P&L
• Mandatory subtotals (operating profit, profit before financing, profit before tax)
• Disclosure depth on business segments and main business activities
• Classification of items between operating and non-operating

For transfer pricing audits, this matters because the P&L structure determines which transactions fall under “main business activity” scrutiny and which don’t. A transaction classified as non-operating in IAS 1 might become operating under IFRS 18, shifting FAR (Functional Analysis and Risk) assessment.

The Transfer Pricing Readiness Checklist

If you have related-party transactions (intercompany loans, management fees, royalties, shared services, cost allocation), start here:

1. Revalidate Your Functional Analysis (FAR)

• Under IFRS 18, “main business activity” is defined by facts, not just revenue size
• Review each transaction: is it core to operations, or peripheral?
• Document the facts that substantiate this classification
• If a transaction moves from peripheral → core (or vice versa), your comparables set may need refresh

Action: Audit your FAR memos. If they don’t explicitly cite IFRS 18 category definitions, rewrite them.

2. Reconcile Journal Entries to P&L Structure

• IFRS 18 requires a specific P&L waterfall
• Intercompany charges (management fees, interest, cost allocations) must be traced from the subledger to the P&L line they land on
• UAE FTA transfer pricing audits now demand this mapping; IFRS 18 makes it unavoidable

Action: Build a reconciliation template linking every intercompany transaction to its IFRS 18 P&L line.

3. Update Transfer Pricing Policy Documentation

• Your TPM (Transfer Pricing Method) decision for each related-party transaction must reference IFRS 18 classification
• Arm’s length range should account for the fact that comparables may shift once IFRS 18 reclassifications are published

Action: Refresh your TP policy memos. Include a section on IFRS 18 impact.

4. Prepare Comparative 2026 Data Now

• Your 2027 financial statements (published early 2028) will show 2026 comparatives under IFRS 18
• Start capturing 2026 transactions in the IFRS 18 chart of accounts *immediately*
• Run a dual-track for the next 6 months: IAS 1 for statutory purposes, IFRS 18 for working papers

Action: Set up a monthly reconciliation between IAS 1 and IFRS 18 presentations. Identify gaps early.

5. Refresh Comparables Analysis

• Comparable companies’ IFRS 18 statements will start appearing in Q1 2027
• Outdated comparables (based on IAS 1 presentations) may become unreliable post-Jan 2027
• Mark your 2025/2026 comparables set as “IAS 1 basis” — you may need to refresh in Q2 2027

Action: Plan a comparables refresh for mid-2027, after enough IFRS 18 data is publicly available.

The UAE-Specific Angle

UAE FTA transfer pricing audits have tightened noticeably since 2024. The combination of:

• Mandatory e-invoicing (live July 1, 2026)
• Strengthened master file/local file requirements
• Now, IFRS 18 reclassifications

…means your intercompany transaction audit trail is more exposed than ever. A misclassification under IFRS 18 can trigger FTA questions about whether your TP documentation was ever robust.

Example: A management fee classified as “administrative expense” under IAS 1 is reclassified as “operating expense” under IFRS 18. The FTA auditor sees the reclassification and asks: “Why wasn’t this cost in your TP policy as operating? Did you miss it, or are you shuffling to hide it?”

Prevention is all about documentation. Document the IFRS 18 reclassification before the FTA asks.

The Practical Timeline

• Now (July 2026): Finalize IFRS 18 chart of accounts and FAR memos
• Aug–Sept 2026: Dry-run 2026 Q1/Q2 data under IFRS 18 format
• Oct–Nov 2026: Finalize 2026 FY data in both IAS 1 and IFRS 18
• Dec 2026: Publish 2025 FS (under IAS 1) + prepare 2026 FS (under IFRS 18)
• Jan 2027: IFRS 18 is live; comparables start shifting

Bottom Line

IFRS 18 doesn’t break transfer pricing. It just makes the existing rules more transparent — and harder to hide mistakes.

If your transfer pricing documentation is solid, IFRS 18 is a non-event. If it’s thin, IFRS 18 is the FTA’s best friend.

Start now. The clock is ticking.
